Several studies have confirmed that maltreatment and abuse in childhood are related to conduct problems. Less is known about such relationships with concurrent adversities in adolescence and, also, when compared with other severe adversities and possible multiple additive effects. The study encompassed a community population of 4881 adolescents 15-16 years of age 50.1 % boys and 49.9 % girls. Youth with and without conduct problem scores within the deviant range on the Strength and Difficulties Questionnaire (SDQ) was compared on 12 concurrent adversities. Based on self-reports, 4.4 % of the adolescents had conduct problem scores within the deviant range and more girls (5.1 %) than boys (3.7 %). In the deviant conduct problem group, 65.1 % had experienced two or more concurrent adversities compared with 26.3 % of youths in the non-deviant group (OR 5.23, 95 % CI 3.91-7.01). Likewise, the deviant conduct problem group was from 1.71 to 8.43 times more at the risk of experiencing the different adversities. Parental mental health problems and experiences of violence were multivariately strongest associated with conduct problem scores within the deviant range on the SDQ. A strong multiple additive relationship with adversities was found. Two-thirds of youth with SDQ conduct problem scores within the deviant range reported two or more concurrent adversities. Clinicians should seek information about kinds and amount of possible traumatic adversities in youth with conduct problems and offer evidence based treatment.

Objective: To investigate the association between the perception of expressed emotion and psychopathology of school-going adolescents in a non-clinical sample. Methods: The cross-sectional field study was conducted in Kocaeli, Turkey, and comprised high-school students during the 2014-15 school years. Data was collected using the Information Collection Form, Strengths and Difficulties Questionnaire and Shortened Level of Expressed Emotion Scale. SPSS 21 was used for data analysis. Results: Of the 487 subjects, 295(60.57%) were girls and 192(39.43%) were boys. The overall median age was 16 (inter-quartile range: 15-17 years). There were significant positive relationships between the scales in terms of emotional problems (p<0.001), behavioural problems (p<0.001), Attention-deficit/hyperactivity disorder (p<0.001), and peer relationship problems (p<0.001). There was also a negative significant relationship between pro-social behaviours and expressed emotion (p<0.001). Conclusion: The concept of perceived expressed emotion in non-clinical adolescents is useful in alarming clinicians and preventing mental disorders.

This study proposes and tests a new model that seeks to explain associations between religion, spirituality and health outcomes among adolescents. Specifically, we test for mediating effects of perceived spirituality on religion-health relations. Using data from the 4-H Study of Positive Youth Development, we find that perceived spirituality mediates religion-health relations, but that varies based on youths' conceptualisation of spirituality. With findings confirming that perceived spirituality potentially promote youths' psychosocial health, we offer some future research directions and implications regarding relations between youths' spirituality, religion and health behaviours.

Purpose The aim of this study is to find out the overall prevalence rates for the major forms of abuse among adolescents in the Kingdom of Saudi Arabia and the differences in prevalence by age, gender and living arrangement. Methods The cross-sectional study was conducted in secondary high schools in five of the 13 main regions of Kingdom of Saudi Arabia during 2012. Through a multistage stratified sampling technique, a sample (n = 16 939) of adolescents (15-19 years) were identified and invited to participate. The ISPCAN Child Abuse Screening Tool-Child was used for data collection. The previous year's occurrence of violence exposure, psychological, physical and sexual abuse, and neglect were assessed. Results Nearly 90% of the adolescents were between 16 and 18 years of age, and over 80% were cared for by both of their biological parents. Annual prevalence of various forms of abuse in the year before the 2012 assessment ranged between 0.10 and 0.65, with the lowest rate for sexual abuse and the highest for psychological abuse. Significantly, greater rates of all forms of abuse/exposure were found when participants lived with their mother or father only (versus with both), and even greater rates for all when they lived with their biological parent and a step-parent. Rates for violence exposure, psychological abuse and neglect were significantly greater for girls, and rate of sexual abuse was greater for boys. Conclusions More attention should be given to the effect of adolescent maltreatment particularly among girls. In addition, sexual abuse prevention programme should be targeted among boys.

Background Studies of children with food allergy typically only include the mother and have not investigated the relationship between the amount of allergen needed to elicit a clinical reaction (threshold) and health-related quality of life (HRQL). Our aims were (i) to compare self-reported and parent-reported HRQL in different age groups, (ii) to evaluate the impact of severity of allergic reaction and threshold on HRQL, and (iii) to investigate factors associated with patient-reported and parent-reported HRQL. Methods Age-appropriate Food Allergy Quality of Life Questionnaires (FAQLQ) were completed by 73 children, 49 adolescents and 29 adults with peanut, hazelnut or egg allergy. Parents (197 mothers, 120 fathers) assessed their child's HRQL using the FAQLQ-Parent form. Clinical data and threshold values were obtained from a hospital database. Significant factors for HRQL were investigated using univariate and multivariate regression. Results Female patients reported greater impact of food allergy on HRQL than males did. Egg and hazelnut thresholds did not affect HRQL, but lower peanut threshold was associated with worse HRQL. Both parents scored their child's HRQL better than the child's own assessment, but whereas mother-reported HRQL was significantly affected by limitations in the child's social life, father-reported HRQL was affected by limitations in the family's social life. Severity of allergic reaction did not contribute significantly to HRQL. Conclusion The risk of accidental allergen ingestion and limitations in social life are associated with worse HRQL. Fathers provide a unique perspective and should have a greater opportunity to contribute to food allergy research.

Pre-ejection period (PEP) reactivity to reward has been posited as a specific index of behavioral approach and incentive motivation, suggesting it might be uniquely associated with the affective and motivational deficits of anhedonia. This study evaluated PEP reactivity to a reward task as a predictor of depressive symptoms among adolescents, examining global depressive symptoms as well as specific anhedonic and nonanhedonic symptoms clusters. Participants included 76 adolescents, ages 11-15 years (52% female). This study found marginal support for an association between PEP reactivity to reward and concurrent anhedonia symptoms, but no association with nonanhedonic or the global scale. Findings are discussed in terms of potential associations between peripheral psychophysiological measures and dopaminergic functioning and also the utility of this measure for future research on anhedonia.

Several studies have recently demonstrated that the volumes of specific brain regions are reduced in children and adolescents with post-traumatic stress disorder (PTSD) compared with those of healthy controls. Our study investigated the potential association between early traumatic experiences and altered brain regions and functions. We conducted a systematic review of the scientific literature regarding functional magnetic resonance imaging and a meta-analysis of structural magnetic resonance imaging studies that investigated cerebral region volumes in pediatric patients with PTSD. We searched for articles from 2000 to 2014 in the PsycINFO, PubMed, Medline, Lilacs, and ISI (Web of Knowledge) databases. All data regarding the amygdala, hippocampus, corpus callosum, brain, and intracranial volumes that fit the inclusion criteria were extracted and combined in a meta-analysis that assessed differences between groups. The meta-analysis found reduced total corpus callosum areas and reduced total cerebral and intracranial volumes in the patients with PTSD. The total hippocampus (left and right hippocampus) and gray matter volumes of the amygdala and frontal lobe were also reduced, but these differences were not significant. The functional studies revealed differences in brain region activation in response to stimuli in the post-traumatic stress symptoms/PTSD group. Our results confirmed that the pediatric patients with PTSD exhibited structural and functional brain abnormalities and that some of the abnormalities occurred in different brain regions than those observed in adults.

Childhood maltreatment is strongly associated with depression, which is characterized by reduced reactivity to reward. Identifying factors that mitigate risk for depression in maltreated children is important for understanding etiological links between maltreatment and depression as well as improving early intervention and prevention. We examine whether high reward reactivity at behavioral and neurobiological levels is a marker of resilience to depressive symptomology in adolescence following childhood maltreatment. A sample of 59 adolescents (21 with a history of maltreatment; Mean Age = 16.95 years, SD = 1.44) completed an fMRI task involving passive viewing of emotional stimuli. BOLD signal changes to positive relative to neutral images were extracted in basal ganglia regions of interest. Participants also completed a behavioral reward-processing task outside the scanner. Depression symptoms were assessed at the time of the MRI and again 2 years later. Greater reward reactivity across behavioral and neurobiological measures moderated the association of maltreatment with baseline depression. Specifically, faster reaction time (RT) to cues paired with monetary reward relative to those unpaired with reward and greater BOLD signal in the left pallidum was associated with lower depression symptoms in maltreated youth. Longitudinally, greater BOLD signal in the left putamen moderated change in depression scores over time, such that higher levels of reward response were associated with lower increases in depression over time among maltreated youths. Reactivity to monetary reward and positive social images, at both behavioral and neurobiological levels, is a potential marker of resilience to depression among adolescents exposed to maltreatment. These findings add to a growing body of work highlighting individual differences in reactivity to reward as a core neurodevelopmental mechanism in the etiology of depression.

While exposure to adverse family experiences (AFEs), subset of adverse childhood experiences (ACEs), has been associated with childhood obesity, less is known about the impact of exposures to each type of AFE. Using 2011-2012 National Survey of Children's Health data, we evaluated associations between exposure to individual AFEs and overweight/obesity status in children 10 years or older, adjusting for socio-demographic factors. Caregivers reported their child's height, weight, and exposure to nine AFEs; body mass index (BMI) was classified by Center for Disease Control and Prevention's (CDC) guidelines. At Mayo Clinic, we calculated frequencies and weighted estimates of socio-demographic factors and AFEs. Unadjusted and adjusted weighted multinomial logistic regression models were employed to assess the independent associations of each AFE and the different AFE composite scores with BMI category. Exposure to two or more AFEs was independently associated with increased odds of overweight (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.13, 1.56) and obese (OR, 1.45; 95% CI, 1.21, 1.73) status after adjustment for age, household income, parents' education-level, race and sex. Death of parent (OR, 1.59; 95% CI, 1.18, 2.15) and hardship due to family income (OR, 1.26; 95% CI, 1.06, 1.50) were independently associated with obesity status with adjustment for other AFEs and socio-demographic factors. Our results suggest that, in addition to cumulative exposure to AFEs, exposure to certain childhood experiences are more strongly associated with childhood obesity than others. Death of parent and hardship due to family income are individual AFEs, which are strongly predictive of obesity. (C) 2016 Elsevier Inc. All rights reserved.

BackgroundIncreasing evidence supports that mentalization deficits may have a role in the genesis of young age depression; however, few studies examined this issue in clinical populations. MethodsOutpatients aged 14-21, suffering from various psychiatric disorders, were assessed using the Mentalization Questionnaire (MZQ), the Beck Depression Inventory (BDI), and the Childhood Trauma Questionnaire (CTQ), using data from age-matched healthy students for comparison. The relationship between CTQ, MZQ, and BDI scores was examined at the cross-sectional level, including mediation analyses, and longitudinally, in a subsample who underwent a psychotherapy intervention. ResultsOf 83 subjects, 33 (39.8%) had mentalization levels that were 1 standard deviation below those of comparison subjects. In the whole sample, the levels of mentalization were inversely associated with BDI (r=-.68, p<.001) and CTQ scores (r=-.30, p=.006). Moreover, MZQ scores mediated a large part of the effect of childhood trauma on depression (total effect: 10.6, 95% CI: 5.3, 15.9; direct effect: 6.5, 95% CI: 2.1, 10.8; indirect effect: 4.1, 95% CI: 1.5, 7.4). This effect was almost entirely explained by the Affect Regulation subscale. In patients re-evaluated after four sessions (n=37), the decrease in BDI scores correlated with the increase in MZQ scores (r=.40, p=.02). ConclusionsIn a juvenile clinical sample, deficits of mentalization abilities were associated with the severity of depression and explained part of the depressogenic effects of childhood trauma.

Social network sites (SNSs) are relatively new phenomena, and the relationship between SNSs and psychopathology remains unclear. The purpose of this study was to evaluate the type of SNSs depressed adolescents use and the incidence of depressive disclosure on SNSs among them. The study was designed to be cross-sectional. The sample consisted of 53 adolescents diagnosed with depressive disorder, as confirmed by K-SADS-PL, and 55 non-depressed adolescents. The Children's Depression Inventory, Social Anxiety Scale and Social Network Use Questionnaire were administered. The primary finding was that the amount of time spent on the Internet and on SNSs was significantly higher among depressed adolescents than non-depressed adolescents. Additionally, depressed adolescents reported significantly higher disclosure of anhedonia, worthlessness, guilt, loss of concentration, irritability and thoughts of suicide on SNSs. The intensity of the depression sharing was significantly higher in the depressed group. Depressed young people use social networks to express their symptoms. Adolescents' disclosure on social networks may be able to guide relatives, friends and mental health professionals.

Introduction: Attention-deficit/hyperactivity disorder (ADHD) and anxiety are frequently comorbid disorders associated with different types of abnormal performance on neuropsychological tests. Although some studies have shown that comorbid anxiety alters ADHD test performance, results inconsistently show both improvements and worsening of different abilities, with failures to replicate across different anxiety disorders. Alternatively, trait anxiety may reflect a more stable influence on ADHD test performance than various diagnosable anxiety disorders. Method: To better understand the possible enhancing or deleterious effects of anxiety on ADHD cognitive impairments, this study examined the effect of individual differences in trait anxiety measured by the Multidimensional Anxiety Scale for Children (MASC) on a battery of computerized, rapid-performance tests measuring attention and impulsivity-related performance in 98 Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-IV) Combined-Subtype ADHD adolescents and 123 healthy controls. It was hypothesized that trait anxiety would attenuate response inhibition and attention deficits in ADHD. Results: ADHD-diagnosed adolescents with higher trait anxiety performed better on indices of sustained attention, reaction time, and motor variability, and had altered overall test-performance strategy, while response inhibition was affected in both ADHD and non-ADHD. Conclusions: This study provides the first evidence that pathological levels of anxiety are not needed to see differences in ADHD neuropsychological test performance. Instead, mildly elevated trait anxiety confers a protective influence by reducing the degree of impairment seen in ADHD. These findings suggest that better performing ADHD adolescents might have optimized levels of cortical arousal, and raise new questions about how best to identify the neurobiological substrates responsible for the beneficial effects.

BackgroundNeglect is often overlooked in adolescence, due in part to assumptions about autonomy and misinterpretation of behaviors being part of normal adolescent development. Emotional maltreatment (abuse or neglect) has a damaging effect throughout the lifespan, but is rarely recognized amongst adolescents. Our review aims to identify features that adolescents experiencing neglect and/ or emotional maltreatment report. MethodA rapid review methodology searched 8 databases (1990-2014), supplemented by hand searching journals, and references, identifying 2,568 abstracts. Two independent reviews were undertaken of 279 articles, by trained reviewers, using standardised critical appraisal. Eligible studies: primary studies of children aged 13-17 years, with substantiated neglect and/ or emotional maltreatment, containing self-reported features. Results19 publications from 13 studies were included, demonstrating associations between both neglect and emotional maltreatment with internalising features (9 studies) including depression, post traumatic symptomatology and anxiety; emotional maltreatment was associated with suicidal ideation, while neglect was not (1 study); neglect was associated with alcohol related problems (3 studies), substance misuse (2 studies), delinquency for boys (1 study), teenage pregnancy (1 study), and general victimization for girls (1 study), while emotionally maltreated girls reported more externalising symptoms (1 study). Dating violence victimization was associated with neglect and emotional maltreatment (2 studies), while emotional abuse of boys, but not neglect, was associated with dating violence perpetration (1 study), and neither neglect nor emotional maltreatment had an association with low self-esteem (2 studies). Neither neglect nor emotional maltreatment had an effect on school performance (1 study), but neglected boys showed greater school engagement than neglected girls (1 study). ConclusionsIf asked, neglected or emotionally maltreated adolescents describe significant difficulties with their mental health, social relationships, and alcohol or substance misuse. Practitioners working with youths who exhibit these features should recognize the detrimental impact of maltreatment at this developmental stage, and identify whether maltreatment is a contributory factor that should be addressed.

Background: Rumination predicts depression in adults and adolescents. The development of rumination has been linked to parenting practices, but only limited research has investigated this and research has tended to rely on self-report parenting measures. Aims: To investigate the relationship between female adolescent rumination and maternal modelling, criticism and positivity using an observational measure of parental behaviour. Method: A cross-sectional design was used. Daughters aged 16-18 years and their mothers (n = 154 dyads) completed questionnaire measures of rumination and affect. Mothers of girls with rumination scores in the upper and lower quartile (both n = 26) also completed the Five Minute Speech Sample, which was used to measure maternal criticism and positivity. Results: Mothers of low rumination girls made significantly more positive comments about their daughters than the mothers of high ruminators. Mothers made very few critical comments. Self-reported rumination was not correlated in mothers and daughters, suggesting a lack of support for the potential role of modelling. Conclusion: Overall, low maternal positivity was associated with rumination in female adolescents. There was no evidence that maternal rumination or criticism were associated with adolescent rumination. The results suggest a number of implications for future research, including the need for prospective longitudinal studies using observational parenting measures.

An Internet-based relapse prevention supplement to adolescent substance abuse treatment programming is a promising modality to reinforce treatment gains and enhance recovery; however, an evidence base is lacking. To assess the efficacy of the online Navigating my Journey (NmJ) program. 129 adolescent-aged participants (ages 13-23) receiving substance abuse treatment participated in a randomized parallel group study comparing two conditions: experimental (NmJ) versus attention control (viewed wellness articles from the Nemours Foundation at their discretion). Participants in the experimental condition were asked to complete 12 core lessons over 3 months. Lesson content was developed to teach evidence-based relapse prevention skills. Data were collected at four time points: baseline, 1-month follow up, 3-month follow up, and 6-month follow up. We used a linear mixed modeling approach to test for differences between conditions on each outcome. Participants in the experimental condition reported a significantly greater increase in motivation to reduce or not misuse drugs from baseline to 3-month follow up and from baseline to 6-month follow up, compared to the control participants. Participants in the experimental condition also reported a greater decrease in drug use score from baseline to 3-month follow up, compared to the control participants. An analysis of age as a potential moderator suggested that the intervention may be more effective for older adolescents. Greater use of the program was associated with greater self-efficacy and lower self-reported substance use over time. Relapse prevention treatment with adolescents may be facilitated by theory-based online interventions. NCT02125539.

Carotenoids are plant secondary metabolites that comprise two main groups: carotenes and xanthophylls. The latter group includes zeaxanthin which is synthesized by beta-carotene hydroxylase catalyzing the hydroxylation of the beta-rings of beta-carotene molecules. To develop tools to alter carotenoid biosynthesis in plants, we isolated a cDNA clone encoding a candidate beta-carotene hydroxylase, CrtH1, from the flower petals of Adonis aestivalis. CrtH1 protein has homology to beta-carotene hydroxylases from other organisms, and possesses the four histidine motifs conserved in this family of enzymes. Sequence analysis predicted the presence of a putative plastid transit peptide at the amino terminus and four transmembrane helical regions. Southern-blot analysis showed CrtH1 to be encoded by a multicopy gene family with at least three members in A. aestivalis. Analysis of CrtH1 transcript abundance by Northern blotting indicates it is highly expressed in flower petals, roots and stems, with relatively low expression in leaves and developing seeds. CrtH1 was able to catalyze the formation of zeaxanthin and its intermediate precursor beta-cryptoxanthin from beta-carotene in functional assays conducted in E. coli. Expression of CrtH1 in Arabidopsis thaliana wild type and a mutant deficient for endogenous beta-carotene hydroxylases enhanced the biosynthesis of violaxanthin in the seeds.

The cDNA AmphiARF , encoding a novel member of ARF family was for the first time identified from the gut cDNA library of amphioxus Branchiostoma becheri tsingtauense . The deduced amino acid sequence includes the motifs involved in GTP binding (DVGG, NKQD and SAK) and hydrolysis (GXDXXGK), and a glycine at position 2 for N-terminal myristoylation, which are all characteristic of ARFs. However, it has a 46 amino acid C-terminal extension (positions 183-227), which was not found in any ARF family previously described including ARF-like proteins. This suggests that AmphiARF is a new member of ARF family, which was also supported by the phylogenetic analysis. It is highly likely that the extended C-terminal of AmphiARF is a novel addition occurring after cephalochordate/vertebrate split. Northern blotting analysis revealed that AmphiARF transcript was present in all tissues examined, consistent with the involvement of ARFs in the fundamental role like vesicular trafficking of proteins.

In whole cell patch-clamp recordings, we characterized the L-type Ca2+ currents in bovine adrenal zona fasciculata (AZF) cells and explored their role, along with the role of T-type channels, in ACTH- and angiotensin II (ANG II)-stimulated cortisol secretion. Two distinct dihydropyridine-sensitive L-type currents were identified, both of which were activated at relatively hyperpolarized potentials. One activated with rapid kinetics and, in conjunction with Northern blotting and PCR, was determined to be Ca(v)1.3. The other, expressed in approximately one-half of AZF cells, activated with extremely slow voltage-dependent kinetics and combined properties not previously reported for an L-type Ca2+ channel. The T-type Ca2+ channel antagonist 3,5-dichloro-N-[1-(2,2-dimethyl-tetrahydro-pyran-4-ylmethyl)-4-fluoro-piperidin-4-ylmethyl]-benzamide (TTA-P2) inhibited Ca(v)3.2 current in these cells, as well as ACTH- and ANG II-stimulated cortisol secretion, at concentrations that did not affect L-type currents. In contrast, nifedipine specifically inhibited L-type currents and cortisol secretion, but less effectively than TTA-P2. Diphenylbutylpiperidine Ca2+ antagonists, including pimozide, penfluridol, and fluspirilene, and the dihydropyridine niguldipine blocked Ca(v)3.2 and L-type currents and inhibited ACTH-stimulated cortisol secretion with similar potency. This study shows that bovine AZF cells express three Ca2+ channels, the voltage-dependent gating and kinetics of which could orchestrate complex mechanisms linking peptide hormone receptors to cortisol secretion through action potentials or sustained depolarization. The function of the novel, slowly activating L-type channel is of particular interest in this respect. Regardless, the well-correlated selective inhibition of T- and L-type currents and ACTH- and ANG II-stimulated cortisol secretion by TTA-P2 and nifedipine establish the critical importance of these channels in AZF cell physiology.

Background Although it has been well established that atrial natriuretic peptide gene-disrupted (ANPS(-/-)) mice are a useful model of salt-sensitive hypertension, surprisingly little is known about the control of their intrarenal renin-angiotensin system (RAS) and pressure-natriuresis mechanism, key components in blood pressure, fluid and electrolyte regulation. The aim of this study was to determine whether ANP disruption results in changes in the renal and adrenal local RAS and the acute pressure natriuresis mechanism. Methods Renal and adrenal renin, angiotensin type 1 (AT(1))((A and B)) and angiotensin type 2 (AT(2)) receptor messenger RNA expression levels were determined by northern blotting or real time reverse transcriptase polymerase chain reaction. Plasma aldosterone and renal and adrenal angiotensin II peptide levels were determined by radioimmunoassay. To examine the acute pressure natriuresis response, changes in renal interstitial hydrostatic pressure (RIHP) were assessed after manipulations of renal arterial pressure (RAP) in anaesthetized mice. Results Renal and adrenal renin mRNA and angiotensin II levels were lower in ANPS(-/-) and (+/-) mice compared with (+/+) mice. ANP(-/-) mice also had greater renal AT(1A) and adrenal AT2 mRNA levels compared with the other genotypes. RAP and RIHP were significantly higher in (-/-) mice compared with (+/+) mice. Furthermore, there was a blunted slope of the RAP-RIHP relationship after increases in RAP in ANP(-/-) mice. Conclusion These data indicate that ANP disruption results in a blunting of the dynamic properties of the acute pressure-natriuresis mechanism at increased levels of RAP, as well as a reduced expression of renal and adrenal local RAS.

Background: Anaphylaxis is a life-threatening emergency of which reliable epidemiological data are lacking. This study aimed to analyze how quickly patients presenting with anaphylaxis were treated in emergency and whether treatment followed the European Academy of Allergy and Clinical Immunology (EAACI) guidelines. Methods: Patient data were collected between April 2009 and April 2013. Emergency doctors completed a questionnaire for adult patients presenting at the emergency department (ED) of the St. Pierre hospital in Brussels with anaphylaxis. Inclusion criteria were based on the Sampson criteria of anaphylaxis. Data were analyzed using a Microsoft Excel database. Results: About 0.04% (100/230878) of all emergency visits in adults presented with anaphylaxis. 64% of patients received their first medical help later than 30 min after symptom onset. 67% of patients received adrenaline, 85% oral antihistamines, and 89% received IV glucocorticosteroids. 46/100 patients were discharged directly from the ED, of which 87% received further medical prescriptions for self-administration: 67% corticosteroids, 83% antihistamines, and 9% intramuscular adrenaline. 74% were instructed to consult an allergologist for adequate diagnosis. 54/100 patients were hospitalized. Conclusion: The majority of patients were treated according to the EAACI guidelines for management of anaphylaxis, but only a minority received the recommended adrenaline auto-injector for self-administration at discharge. Because the majority of patients received medical help later than 30 min after symptom onset, adrenaline auto-injector prescription is a necessity. The low rate of doctors prescribing adrenaline auto-injectors in the ED setting underlines the need to train doctors of various backgrounds in prevention and treatment of anaphylaxis and the close collaboration with allergologists.

BACKGROUND: Allergy immunotherapy can result in systemic allergic reactions and even life-threatening anaphylaxis requiring epinephrine administration. OBJECTIVE: The objective of this study was to describe epinephrine use in the clinical trial development programs of 3 rapidly dissolving sublingual immunotherapy tablets (SLITtablets; Merck & Co., Inc., Kenilworth, NJ/ALK, Horsholm, Denmark/Torii Pharmaceutical Co., Ltd., Tokyo, Japan). METHODS: Data on epinephrine use were collected from 13 timothy grass SLIT-tablet trials (MK-7243; <= 2800 bioequivalent allergen units/75,000 SQ-T dose, n =2497; placebo, n = 2139), 5 short ragweed SLIT-tablet trials (MK-3641; <= 12 Amb a 1-U, n =1725; placebo, n =770), and 11 house dust mite (HDM) SLIT-tablet trials (MK-8237; <= 12 SQ-HDM; n=3930; placebo, n =2246). RESULTS: In grass SLIT-tablet trials, epinephrine was used 13 times (grass SLIT-tablet, n =10; placebo, n =3). Eight administrations were for grass SLIT-tablet-related adverse events (AEs): 4 for systemic allergic reactions and 4 for local mouth and/or throat swelling. In ragweed SLIT-tablet trials, epinephrine was used 9 times in 8 subjects (ragweed SLIT-tablet, n =7; placebo, n =1 =2 administrations for protracted anaphylaxis]). Four administrations were for ragweed SLIT-tablet-related AEs: 1 for systemic allergic reaction and 3 for local mouth and/or pharynx/throat swelling. In HDM SLIT-tablet trials, epinephrine was administered 13 times (HDM SLIT-tablet, n =8; placebo, n =5). Four administrations were for HDM SLITtablet- related AEs: 1 for systemic allergic reaction and 3 for local events. Of the 16 epinephrine administrations for events related to SLIT-tablet treatment, 11 occurred within the first week of treatment (7 administrations on day 1) and 5 were subject self-administered. CONCLUSIONS: Epinephrine administrations in response to SLIT-tablet-related reactions in clinical trials are uncommon, typically occur within the first week of treatment, and are rarely self-administered. All SLIT-tablet-related events treated with epinephrine were nonserious. (C) 2016 American Academy of Allergy, Asthma & Immunology

3 beta-Hydroxysteroid dehydrogenase type II deficiency (3 beta HSD2) congenital adrenal hyperplasia is a rare cause of ambiguous genitalia, resulting in abnormal virilisation in both 46XY and 46XX. We describe a case of 46XY ambiguous genitalia that was misdiagnosed as androgen insensitivity syndrome. The correct diagnosis was made after adrenarche. Genotyping demonstrated compound heterozygosity in two alleles, the previously described c.244G >A (p.Ala82Thr), and a novel 931C >.T(p. Gln311*) variant. We suggest that adrenarche unmasked the condition by driving cortisol production to rates that caused the mutant 3bHSD2 enzyme to become rate limiting for cortisol production. This case illustrates how markedly different the effects of this condition may be on androgen production compared with glucocorticoid and mineralocorticoid production. It also demonstrates how current guidelines based on urinary steroids and cortisol sufficiency may not arrive at the correct diagnosis, and underlines the importance of gene testing in the work-up of disorders of sexual differentiation.

Background: Attachment anxiety and avoidance have been found to be associated with worry. A substantial body of research suggests that intolerance of uncertainty (IOU) is a phenomenon which predicts level of worry, yet the relationship between attachment, IOU and worry remains to be investigated. Methods: The present study recruited 281 participants from the community within Australia to complete an online survey incorporating the Intolerance of Uncertainty Scale, the Experiences in Close Relationships Scale-Revised, and the Penn State Worry Questionnaire. Results: The analyses revealed attachment anxiety and attachment avoidance were positively correlated with IOU, and that attachment anxiety, attachment avoidance and IOU were positively correlated with worry. Furthermore, IOU was found to mediate the relationship between attachment anxiety and worry, even when attachment avoidance was entered as a covariate. By contrast, for the relationship between attachment avoidance and worry, intolerance of uncertainty only mediated the association if attachment anxiety was ignored. Conclusions: The results of the study suggest that IOU may play a key role in the relationship between adult attachment difficulties and the experience of worry. These findings may have significant implications for the conceptualisation and psychological treatment of attachment related difficulties. (C) 2017 Elsevier Ltd. All rights reserved.

Context: Psychosocial factors can impact lung transplant outcomes. However, it is currently unknown whether abuse survivorship influences lung transplant survival. Objective: To characterize the abuse history of adult lung transplant patients and determine whether such history is associated with mortality. Patients and Other Participants: Adult lung transplant recipients evaluated from 2000 to 2004. Main Outcome Measures: The main outcome was post-lung transplantation survival. The secondary outcomes included demographic, transplantation, or psychological assessment differences between those with a history of abuse survivorship and those without. Results: Thirty-three lung transplant recipients (35.5% male, median age: 55 years) were included. A history of abuse survivorship was common (24.2%) and was associated with decreased survival following lung transplantation (P = .003). There was no difference in sex, marital status, or smoking history between abuse survivors and those who denied being the victim of abuse. Abuse survivors had a higher Personality Assessment Screener total score, a measure of maladaptive personality traits (P = .02). Conclusion: Abuse survivorship is common in lung transplant patients and associated with increased posttransplant mortality and increased maladaptive personality traits. This preliminary evidence suggests that lung transplant patients should be screened for abuse history and provided with appropriate treatment of survivorship issues to potentially improve their health outcomes from transplantation.

Background: Symptom clusters have not previously been explored among individuals with atrial fibrillation of any type. Objective: The purpose of this study is to determine the number of symptom clusters present among adults with chronic atrial fibrillation and to explore sociodemographic and clinical factors potentially associated with cluster membership. Methods: This was a cross-sectional secondary data analysis of 335 Australian community-dwelling adults with chronic (recurrent paroxysmal, persistent, or permanent) atrial fibrillation. We used self-reported symptoms and agglomerative hierarchical cluster analysis to determine the number and content of symptom clusters present. Results: There were slightly more male (52%) than female participants, with a mean (SD) age of 72 (11.25) years. Three symptom clusters were evident, including a vagal cluster (nausea and diaphoresis), a tired cluster (fatigue/lethargy, weakness, syncope/dizziness, and dyspnea/breathlessness), and a heart cluster (chest pain/discomfort and palpitations/fluttering). We compared patient characteristics among those with all the symptoms in the cluster, those with some of the symptoms in the cluster, and those with none of the symptoms in the cluster. The only statistically significant differences were in age, gender, and the use of antiarrhythmic medications for the heart cluster. Women were more likely to have the heart symptom cluster than men were. Individuals with all of the symptoms in the heart cluster were younger (69.6 vs 73.7 years; P = .029) than those with none of the symptoms in the heart cluster and were more likely to be on antiarrhythmic medications. Conclusion: Three unique atrial fibrillation symptom clusters were identified in this study population.

This review discusses the unmet needs of patients with attention deficit/hyperactivity disorder (ADHD) who are transitioning into adulthood. Although awareness and recognition of ADHD in children, adolescents, and adults have improved in recent years, there is often an interruption in management of the disorder when adolescent patients transition to adult health care services. This review has the following objectives: (1) to identify key issues patients with ADHD (with or without an early diagnosis) face during transition into adulthood; (2) to review the current clinical practice and country-specific approaches to the management of the transition into adulthood for patients with ADHD; (3) to discuss challenges facing clinicians and their patients when drug treatment for ADHD is initiated; (4) to review current ADHD guidelines on transition management in Hong Kong, Singapore, South Korea, Turkey, and Africa; and (5) to examine economic consequences associated with ADHD. The review suggests that the transition period to adult ADHD may be an underresearched and underserved area. The transition period plays an important role regarding how ADHD symptoms may be perceived and acted upon by adult psychiatrists. Further studies are needed to explore the characteristics of the transition period. If only a fraction of adolescents go on to have mental disorders during adulthood, especially ADHD, it is crucial to identify their characteristics to target appropriate interventions at the beginning of the course of illness. There continues to be low recognition of adult ADHD and a severe lack of medical services equipped to diagnose and care for patients with ADHD transitioning from child to adult services.

Recent studies have examined non-suicidal self-injury in community and clinical samples, but there is no published research on non-suicidal self-injury in individuals with autism spectrum disorder. This lack of research is surprising, since individuals with autism spectrum disorder have high rates of risk factors for non-suicidal self-injury, including depression and poor emotion regulation skills. Using an online survey, we examined non-suicidal self-injury methods, frequency, severity, functions, and initial motivations in adults with autism spectrum disorder (n=42). We also compared their non-suicidal self-injury characteristics to those of a gender-matched group of adults without autism spectrum disorder (n=42). Of the participants with autism spectrum disorder, 50% reported a history of non-suicidal self-injury. This proportion is higher than non-suicidal self-injury rates previously reported for college students, adult community samples, and adolescents with autism spectrum disorder, which suggests that adults with autism spectrum disorder have increased risk for engaging in non-suicidal self-injury. Women with autism spectrum disorder were significantly more likely to endorse non-suicidal self-injury, relative to men with autism spectrum disorder. A history of non-suicidal self-injury was not related to current depression or emotion dysregulation for the participants with autism spectrum disorder. Non-suicidal self-injury characteristics among the adults with autism spectrum disorder were similar to non-suicidal self-injury in adults without autism spectrum disorder. These preliminary findings highlight the need for increased awareness and further research about non-suicidal self-injury within autism spectrum disorder.

Field programmable gate arrays (FPGAs) have established themselves as one of the preferred digital implementation platforms in a plethora of current industrial applications, and extensions and improvements are still continuously being included in the devices. This paper reviews recent advancements in FPGA technology, emphasizing the novel features that may significantly contribute to the development of more efficient digital systems for industrial applications. Special attention is paid to the design paradigm shift caused by the availability of increasingly powerful embedded (and soft) processors, which transformed FPGAs from hardware accelerators to very powerful system-on-chip (SoC) platforms. New analog resources, floating-point operators, and hard memory controllers are also described, because of the great advantages they provide to designers. Software tools are being strongly influenced by the design paradigm shift, which requires fromthem a much better support for software developers. Focusing mainly on this issue, recent advancements in software resources [intellectual property (IP) cores and design tools] are also reviewed. The impact of new FPGA features in industrial applications is analyzed in detail in three main areas, namely digital real-time simulation, advanced control techniques, and electronic instrumentation, with focus on mechatronics, robotics, and power systems design. The way digital systems are being currently designed in these areas is comprehensively reviewed, and a critical analysis of how they could significantly benefit from new FPGA features is presented.

Research documents how exposure to adversity in childhood leads to negative health outcomes across the lifespan. Less is known about protective factors - aspects of the individual, family, and community that promote good health despite exposure to adversity. Guided by the Resilience Portfolio Model, this study examined protective factors associated with physical health in a sample of adolescents and adults exposed to high levels of adversity including child abuse. A rural community sample of 2565 individuals with average age of 30 participated in surveys via computer assisted software. Participants completed self-report measures of physical health, adversity, and a range of protective factors drawn from research on resilience. Participants reporting a greater burden of childhood victimization and current financial strain (but not other adverse life events) had poorer physical health, but those with strengths in emotion regulation, meaning making, community support, social support, and practicing forgiveness reported better health. As hypothesized, strengths across resilience portfolio domains (regulatory, meaning making, and interpersonal) had independent, positive associations with health related quality of life after accounting for participants' exposure to adversity. Prevention and intervention efforts for child maltreatment should focus on bolstering a portfolio of strengths. The foundation of the work needs to begin with families early in the lifespan.

Background: Given growing numbers of older adults with mental and substance use disorders (MSUDs), this study examined the association between ten types of adverse childhood experiences (ACEs) and lifetime MSUDs among those aged 50+. Methods: Data (N=14,738 for the 50+ age group) came from the 2012 to 2013 National Epidemiologic Survey on Alcohol and Related Conditions. Using multivariable binary logistic regression analyses, we examined relationships between ten ACEs and six lifetime MSUDs (major depressive disorder (MDD) and anxiety, post-traumatic stress, alcohol use, drug use, and nicotine use disorders). Gender differences were examined using tests of interaction effects and gender-separate logistic regression models. Results: Of the sample, 53.2% of women and 50.0% of men reported at least one ACE. For both genders, parental/other adult's substance abuse was the most prevalent (22.6%), followed by physical abuse, and emotional neglect. Child abuse and neglect and parental/other adult's mental illness and substance abuse had small but consistently significant associations with MSUDs (e.g., odds ratio = 1.28, 95% CI= 1.12-1.46 for parental/other adult's substance misuse and MDD). Although the relationship between total number of ACEs andMSUDs was cumulative for both men and women, the associations of physical abuse, sexual abuse, emotional neglect, and parental separation/divorce with MSUDs were stronger among men. Conclusions: This study underscores the significant yet modest association between ACEs and lifetime MSUDs in late life. More research is needed to investigate why ACEs seem to have greater effects on older men and to discern the sources of gender differences in ACEs' effects.

Background: Adverse childhood experiences (ACEs) have been associated with an increased risk of a variety of diseases, including cancer. However, research has largely ignored how ACEs impact cancer screening, a potential intermediate outcome. As such, the present study examined the association between ACEs and ever and recent use of Papanicolaou (Pap) test, among women aged 21 and older. Materials and Methods: Analyses used the 2009 Tennessee Behavioral Risk Factor Surveillance System (n = 1527) to model odds of ever and recently (within the last 3 years) engaging in Pap tests screening from nine different adversities. Bivariate and multivariate logistic regression models were run to accomplish this. Results: In bivariate and multivariate models, living in a household in which adults treated each other violently increased odds of ever receiving a Pap test. In bivariate models, physical and sexual abuse was associated with decreased odds of receiving a recent Pap test. After accounting for confounders, only the latter association remained significant. Conclusions: Results highlight a potential mechanism by which early childhood experiences can impact the development of cervical cancer. Providers of care should consider modifications to their screening practices, including screening for child abuse, to better serve all women.

Substantial research shows that early adversity, including child abuse and neglect, is associated with diminished health across the life course and across generations. Less well understood is the relationship between early adversity and adult socioeconomic status, including education, employment, and income. Collectively, these outcomes provide an indication of overall life opportunity. We analyzed data from 10 states and the District of Columbia that used the adverse childhood experiences (ACE) module in the 2010 Behavioral Risk Factor Surveillance System to examine the association between ACEs and adult education, employment, and income. Compared to participants with no ACEs, those with higher ACE scores were more likely to report high school non-completion, unemployment, and living in a household below the federal poverty level. This evidence suggests that preventing early adversity may impact health and life opportunities that reverberate across generations. Current efforts to prevent early adversity might be more successful if they broaden public and professional understanding (i.e., the narrative) of the links between early adversity and poverty. We discuss our findings within the context of structural policies and processes that may further contribute to the intergenerational continuity of child abuse and neglect and poverty.

Adverse childhood experiences (ACEs) have been linked to increased use of tobacco products later in life. However, studies to date have ignored smokeless tobacco products. To address this, data from the 2011 Behavioral Risk Factor Surveillance System, which interviewed adults 18 years and over (N = 102,716) were analyzed. Logistic regression models were fit to estimate odds ratios of ever smoking, current smoking and current smokeless tobacco use in relation to ACEs. Results showed that less than 4 % of respondents currently used smokeless tobacco products, while 44.95 and 18.57 % reported ever and current smoking, respectively. Physical abuse (OR 1.40; 95 % CI 1.14, 1.72), emotional abuse (OR 1.41; 95 % CI 1.19, 1.67), sexual abuse (OR 0.70; 95 % CI 0.51, 0.95), living with a drug user (OR 1.50; 95 % CI 1.17, 1.93), living with someone who was jailed (OR 1.50; 95 % CI 1.11, 2.02) and having parents who were separated or divorced (OR 1.31; 95 % CI 1.09, 1.57) were associated with smokeless tobacco use in unadjusted models. After accounting for confounders, physical abuse (OR 1.43; 95 % CI 1.16, 1.78), emotional abuse (OR 1.32; 95 % CI 1.10, 1.57), living with a problem drinker (OR 1.30; 95 % CI 1.08, 1.58), living with a drug user (OR 1.31; 95 % CI 1.00, 1.72) and living with adults who treated each other violently (OR 1.30; 95 % CI 1.05, 1.62) were associated with smokeless tobacco use. Living with someone who was mentally ill (OR 0.70; 95 % CI 0.53, 0.92) was associated with smokeless tobacco use after accounting for confounders and all ACEs. Results indicated that some childhood adversities are associated with use of smokeless tobacco products. Special attention is needed to prevent tobacco use of different types among those experiencing ACEs.

Objective: To ascertain efficacy and tolerability of carbamazepine (CBZ), sodium valproate (VPA), lamotrigine (LTG) and levetiracetam (LEV) using the UKAED register (www.ukaed.info). Methods: Patients on CBZ (n=91), VPA (n=61), LTG (n=105), LEV (n=72) and healthy control subjects (CTR) on no medication (n=51) were extracted. All patients had anonymously provided information on seizure type and frequency and completed the Liverpool Adverse Event Profile (LAEP). Results: The number of seizure-free patients in the last 4 weeks was overall CBZ/VPA /LTG/LEV=60%/79%/67%/67%, for generalized epilepsy was CBZ/VPA/LTG/LEV=67%/89%/65%/94%, and for localization-related epilepsy was CBZ/VPA/LTG/LEV=59%/71%/67%/57%. Mean LAEP scores were CBZ/VPA/LTG/LEV/CTR=42.21/39.66/39.86/43.01/29.69. The mean LAEP was significantly higher in patients reporting depression and in patients with active epilepsy than in patients without depression and remission. Central nervous system (CNS) adverse effects including memory problems, difficulty concentrating, depression, unsteadiness, restlessness, feelings of anger, shaky hands and dizziness were significantly more frequent in CBZ, VPA, LTG and LEV than in CTR. The feeling of anger was significantly more frequent in LEV, and depression was significantly more frequent in CBZ compared to the other drugs. Conclusion: In this Internet-based register of self-reported efficacy and tolerability, CBZ, VPA, LTG and LEV were similar. Self-reported CNS adverse effects were significantly more frequent than in controls. In addition, anger was associated with LEV and depression with CBZ. Confounding factors were depression and uncontrolled epilepsy.

Background: Aeluropus lagopoides is a salt and drought tolerant grass from Poaceae family, distributed widely in arid regions. There is almost no information about the genetics or genome of this close relative of wheat that stands harsh conditions of deserts. Objectives: The main aim of this research was to isolation and characterization of salt and drought inducible genes from A. lagopoides by Differential Display Amplified fragment length polymorphism (DD-AFLP) method. Material and Methods: In this research A. lagopoides was grown under salt or drought conditions and after modifying the DD-AFLP method several fragments were isolated and after nomination their induction was studied by reverse northern blotting. Results: DD-AFLP led to the improvement of a non-radioactive method for which many parameters were optimized. Having screened approximately 1600 transcript-derived fragments, 1.4 percent of them showed varied expression levels in response to high salt or drought treatments. The relative abundance of twenty one selected differentially expressed fragments was inspected by reverse northern blotting that affirmed the potential of this applied method. Sequence comparisons revealed that some of the isolated genes are involved in osmotic adjustment, regulation of transcription, cation transportation and stress responses. These data clearly show that the modified DD-AFLP method was a successful and reliable approach for the isolation of differentially expressed genes.

We had previously reported that Vibrio hollisae produces aerobactin in response to iron starvation. In the present study, we identified in V hollisae ATCC33564 the aerobactin system cluster which consists of eight genes, hatCDB, iucABCD and iutA. The hatCDB genes encode proteins homologous to components of bacterial ATP binding cassette transport systems for ferric aerobactin. The iucABCD and iutA orthologs code for aerobactin biosynthesis enzymes and the ferric aerobactin receptor, respectively. In accordance with their iron-regulated expression, putative Fur box sequences were found within the respective promoter regions of hatC, iucA and iutA. The monocistronic iutA transcript was detected by northern blotting. Moreover, phenotypic comparison between the wild-type strain and its targeted gene disruptants supported the biological functions that were expected for the respective operons and genes on the basis of the homology search. The arrangement of the aerobactin gene clusters thus far found in Vibrio and enterobacterial species was compared and discussed from an evolutionary point of view. (c) 2006 Elsevier SAS.

Active Electronically Scanned Array (AESA) technology will enable next generation radars achieve better jamming resistance capability and low probability of intercept by spreading their emissions over a wide frequency range. These radars systems consist of a large number of transmit/receive modules (TRMs) which are electronically scanned in a tight time-synchronized manner. This requires digital control to move closer to the radio front end on the antennas. Other emerging technologies, such as cognitive radars and MIMO radars, will continue to drive the need for complex timing, synchronization, and high mix RF and digital measurement requirements. To meet these challenges, radar engineers will need a platform based approach which delivers capabilities such as multi-channel phase aligned measurements over wide bandwidths and high-throughput streaming. This paper discusses the fundamentals of AESA radars and trends in radar systems. It analyzes the impact of these trends on test system architecture and explains how the advances in PXI modular instrumentation can meet these challenging requirements.

Obesity continues to be a major global problem. Various cancers are related to obesity and proper understanding of their aetiology, especially their molecular tumour biology is important for early diagnosis and better treatment. Genes play an important role in the development of obesity. Few genes such as leptin, leptin receptor encoded by the db (diabetes), pro-opiomelanocortin, AgRP and NPY and melanocortin-4 receptors and insulin-induced gene 2 were linked to obesity. MicroRNAs control gene expression via mRNA degradation and protein translation inhibition and influence cell differentiation, cell growth and cell death. Overexpression of miR-143 inhibits tumour growth by suppressing B cell lymphoma 2, extracellular signal-regulated kinase-5 activities and KRAS oncogene. Cancers of the breast, uterus, renal, thyroid and liver are also related to obesity. Any disturbance in the production of sex hormones and insulin, leads to distortion in the balance between cell proliferation, differentiation and apoptosis. The possible mechanism linking obesity to cancer involves alteration in the level of adipokines and sex hormones. These mediators act as biomarkers for cancer progression and act as targets for cancer therapy and prevention. Interestingly, many anti-cancerous drugs are also beneficial in treating obesity and vice versa. We also reviewed the possible link in the mechanism of few drugs which act both on cancer and obesity. The present review may be important for molecular biologists, oncologists and clinicians treating cancers and also pave the way for better therapeutic options.

ObjectiveThe aim of our study was to investigate, in bipolar patients, whether affect lability was associated with suicidal ideation incidence during 2-year follow-up, and which subtype of affect lability was associated with suicidal ideation. MethodA total of 319 euthymic or mildly depressed bipolar outpatients recruited in the French FondaMental Advanced Centres of Expertise for Bipolar Disorder were divided into two subgroups according to the occurrence of suicidal ideation during a 2-year follow-up. Affect lability was assessed by the French version of the Affect Lability Scale. ResultsBipolar patients with high affect lability were more likely to report suicidal ideation during follow-up, even after adjustment for age, study level, rapid cycling, current depression level, anxiety disorder, and lifetime history SA (OR = 2.47; 95% CI [1.15-5.30], P = 0.01). The risk of suicidal ideation increased with the level of affect lability. More specifically, the propensity to switch from neutral to elation affect, from anxious to depressive affect (or inversely), and from neutral to anger affect predicted suicidal ideation. ConclusionReducing affective lability could become a new therapeutic target of suicidal prevention in bipolar disorder.

Objective: To examine the association between gestational age (GA) at birth across the normal GA spectrum (37-41 weeks) and the temperament and health of 3-month old infants.Methods: The sample comprised 242 low-risk mothers and infants without chronic illnesses or severe pregnancy complications. Infant temperament was defined by three constructs: Negative Affectivity (NA), Extraversion, and Regulation, assessed by parents' reports on the Infant Behavior Questionnaire. Infants' health was defined as the number of nonroutine doctors' visits attended by the infants since their release from the hospital after birth. Analyses employed a continuous measure of GA to assess outcomes across GAs and a categorical measure (37, 38, 39-41 weeks GA) to examine contrasts.Results: Extraversion was positively related to GA primarily due to the lower scores of infants born at 37 weeks compared to infants born at 39-41 weeks GA. NA showed a similar effect. The odds of infants born at 37 weeks attending a nonroutine medical visit were 2.8 times that of infants born full-term.Discussion: Infants born at 37 weeks GA express less affect and use more nonroutine medical services than do infants born at 39-41 weeks GA. The findings underscore the importance of considering the risks of pregnancy prolongation with the developmental risk associated with early-term delivery.

Background: The ability to recognize emotional expression is essential for social interactions, adapting to the environment, and quality of life. Emotion recognition is impaired in people with Alzheimer's disease (AD), thus rehabilitation of these skills has the potential to elicit significant benefits. Objective: This study sought to establish whether emotion recognition capacity could be rehabilitated in people with AD. Methods: Thirty-six participants with AD were assigned to one of three conditions: an experimental group (EG) that received 20 sessions of rehabilitation of emotion recognition and 20 sessions of cognitive stimulation therapy (CST), a control group (CG) that received 40 sessions of CST, and a treatment as usual group (TAU). Results: A positive treatment effect favoring the EG was found; participants were better able to correctly identify emotions (p = 0.021), made fewer errors of commission (p = 0.002), had greater precision of processing (p = 0.021), and faster processing speed (p = 0.001). Specifically, the EG were better able to identify sadness (p = 0.016), disgust (p = 0.005), and the neutral expression (p = 0.014), with quicker processing speed for disgust (p = 0.002). These gains were maintained at one month follow-up with the exception of processing speed for surprise, which improved. Conclusion: Capacity to recognize facial expressions of emotions can be improved through specific rehabilitation in people with AD, and gains are still present at a one month follow up. These findings have implications for the design of rehabilitation techniques for people with AD that may lead to improved quality of life and social interactions for this population.

In response to Palermo (2016, Australian Psychologist, in press) comments, some aspects of the target paper are further elaborated here. In particular, given Palermo's timely emphasis on the potential social and cultural implications of research demonstrating the beneficial consequences of negative affect, the historical background, and practical implications of the experimental evidence are elaborated. Furthermore, the reviewer also comments on the applicability of alternative theoretical conceptualizations to the data reported here, and this issue also receives further attention. Overall, it is concluded that there is now strong and convergent evidence for the often beneficial consequences of mild negative affect, and these findings deserve serious consideration in practical applications of psychology, and in our conceptions of what represents a healthy and balanced emotional life. Embracing and accepting periods of negative affectivity should be recognised as a normal and healthy part of the human condition, and the cultural bias towards positive affect should be tempered by an appreciation of the adaptive benefits of dysphoria.

The subtle relationship between feeling and thinking, affect and cognition has fascinated philosophers and writers since time immemorial, yet, empirical research on this topic was relatively neglected by psychologists until recently. There have been many claims emphasising the beneficial cognitive and behavioural consequences of positive affect. Many recent works suggest that negative affect may also facilitate optimal performance in many situations, consistent with evolutionary theories suggesting the adaptive signalling function of various affective states. This paper reviews traditional and current psychological theories linking affect to social thinking and behaviour. A variety of empirical studies from our laboratory will also be presented, demonstrating that in many situations, negative affect promotes optimal performance in cognitive and social tasks, including tasks such as memory, social judgements, motivation, and strategic interpersonal behaviours. These results will be interpreted in terms of a dual-process theory that predicts that negative affect promotes a more accommodative, vigilant, and externally focused thinking strategy. The relevance of these findings for recent affect-cognition theories will be discussed, and the practical implications of negative affect promoting improved social thinking and performance in a number of applied fields will be considered.

Background: One in twenty-five people suffer from a mood disorder. Current treatments are sub-optimal with poor patient response and uncertain modes-of-action. There is thus a need to better understand underlying mechanisms that determine mood, and how these go wrong in affective disorders. Systems biology approaches have yielded important biological discoveries for other complex diseases such as cancer, and their potential in affective disorders will be reviewed. Scope of review: This review will provide a general background to affective disorders, plus an outline of experimental and computational systems biology. The current application of these approaches in understanding affective disorders will be considered, and future recommendations made. Major conclusions: Experimental systems biology has been applied to the study of affective disorders, especially at the genome and transcriptomic levels. However, data generation has been slowed by a lack of human tissue or suitable animal models. At present, computational systems biology has only be applied to understanding affective disorders on a few occasions. These studies provide sufficient novel biological insight to motivate further use of computational biology in this field. General significance: In common with many complex diseases much time and money has been spent on the generation of large-scale experimental datasets. The next step is to use the emerging computational approaches, predominantly developed in the field of oncology, to leverage the most biological insight from these datasets. This will lead to the critical breakthroughs required for more effective diagnosis, stratification and treatment of affective disorders. (C) 2016 Elsevier B.V. All rights reserved.

Individuals can apply different processing strategies to deal with situations they encounter. One central question in social-cognition research refers to the factors that determine reliance on different processing strategies. Parting from a functional perspective, which holds that processing strategies need to be adjusted to the requirements of the situation, we argue that individuals' mood carries information about the benign versus problematic nature of the situation and thus that mood can regulate cognitive processing. Focusing on mental abstraction, we propose that positive mood contributes to a processing style characterized by reliance on prior knowledge in the form of general knowledge structures, whereas negative mood elicits a processing style characterized by attention to details and consideration of new situation-specific information.

Most broadly neutralizing antibodies (BNAbs) elicited in response to HIV-1 infection are extraordinarily mutated. One goal of HIV-1 vaccine development is to induce antibodies that are similar to the most potent and broad BNAbs isolated from infected subjects. The most effective BNAbs have very high mutation frequencies, indicative of the long periods of continual activation necessary to acquire the BNAb phenotype through affinity maturation. Understanding the mutational patterns that define the maturation pathways in BNAb development is critical to vaccine design efforts to recapitulate through vaccination the successful routes to neutralization breadth and potency that have occurred in natural infection. Studying the mutational changes that occur during affinity maturation, however, requires accurate partitioning of sequence data into B-cell clones and identification of the starting point of a B-cell clonal lineage, the initial V(D)J rearrangement. Here, we describe the statistical framework we have used to perform these tasks. Through the recent advancement of these and similar computational methods, many HIV-1 ancestral antibodies have been inferred, synthesized and their structures determined. This has allowed, for the first time, the investigation of the structural mechanisms underlying the affinity maturation process in HIV-1 antibody development. Here, we review what has been learned from this atomic-level structural characterization of affinity maturation in HIV-1 antibodies and the implications for vaccine design.

Alterations in mitochondrial respiration contribute to the development and progression of cancer via abnormal biogenesis, including generation of reactive oxygen species. Ubiquinol-cytochrome c reductase hinge protein (UQCRH) consists of the cytochrome bc1 complex serving respiration in mitochondria. In the present study, we analyzed UQCRH abnormalities in hepatocellular carcinoma (HCC) and its association with clinical outcomes of patients. UQCRH expression in HCC was determined via semiquantitative and quantitative real-time reverse transcriptase polymerase chain reaction of 96 surgically resected HCC tissues positive for hepatitis B virus surface antigen. UQCRH was frequently overexpressed in HCC tissues (46.8%, based on 2.1-fold cutoff). UQCRH overexpression was observed in HCCs with larger tumor size, poorer differentiation, or vascular invasion. Kaplan-Meier analysis revealed significantly shorter overall (P=0.005) and recurrence-free survival (P=0.027) in patients with tumors overexpressing UQCRH. The prognostic impact of UQCRH was significant in subgroups of patients divided according to the -fetoprotein (AFP) level. The patient subgroup with higher AFP levels (20ng/mL) exhibited significant differences in 5-year overall (18.5% vs. 67.9%) and recurrence-free survival rates (11.1% vs. 46.4%) between groups with and without UQCRH overexpression. In contrast, no marked survival differences were observed between subgroups with lower AFP levels (<20ng/mL). Multivariate analysis defined UQCRH as an independent poor prognostic factor. Conclusively, our results indicate that UQCRH overexpression is correlated with poor outcomes of HCC patients. Furthermore, in patients grouped as high risk based on elevated AFP, lack of UQCRH overexpression could be a useful indicator for clinical treatment.

Recent forecasts suggest that African countries must triple their current electricity generation by 2030. Our multicriteria assessment of wind and solar potential for large regions of Africa shows how economically competitive and low-environmental-impact renewable resources can significantly contribute to meeting this demand. We created the Multicriteria Analysis for Planning Renewable Energy (MapRE) framework to map and characterize solar and wind energy zones in 21 countries in the Southern African Power Pool (SAPP) and the Eastern Africa Power Pool (EAPP) and find that potential is several times greater than demand in many countries. Significant fractions of demand can be quickly served with "no-regrets" options-or zones that are low-cost, low-environmental impact, and highly accessible. Because no-regrets options are spatially heterogeneous, international interconnections are necessary to help achieve low-carbon development for the region as a whole, and interconnections that support the best renewable options may differ from those planned for hydropower expansion. Additionally, interconnections and selecting wind sites to match demand reduce the need for SAPP-wide conventional generation capacity by 9.5% in a high-wind scenario, resulting in a 6-20% cost savings, depending on the avoided conventional technology. Strategic selection of low-impact and accessible zones is more cost effective with interconnections compared with solutions without interconnections. Overall results are robust to multiple load growth scenarios. Together, results show that multicriteria site selection and deliberate planning of interconnections may significantly increase the economic and environmental competitiveness of renewable alternatives relative to conventional generation.

X-linked agammaglobulinemia (XLA) has been associated with a broad range of infections, but enteroviral disease represents one of the most damaging infections. The risk of enteroviral infection in XLA is lower now than in the setting of intramuscular immunoglobulin or in patients without immunoglobulin replacement, but the rate of infection has not declined significantly in the era of intravenous immunoglobulin replacement. Enteroviruses can cause inflammation of nearly every organ, but in XLA, infections often manifest as dermatomyositis or chronic meningoencephalitis. Difficulty and delay in recognizing symptoms and lack of specific therapy contribute to the poor outcomes. Furthermore, cerebrospinal fluid detection of enteroviruses is not very sensitive. Reluctance to perform brain biopsies can lead to significant delays. The other feature compromising outcomes is the lack of specific therapy. High-dose peripheral and intraventricular immunoglobulin have been used, but failure is still common. New antienteroviral drugs are in development and show promise for immunodeficient patients with life-threatening infections with enterovirus.

This paper presents a 1V -70dB THD audio Automatic Gain Control (AGC) circuits. The proposed AGC is based on feedback topologies and the gain is digital controlled. A pi-type resistors network is used in the Programmable Gain Amplifier (PGA) as the passive feedback device to realize gain linearity in decibels and increase the gain accuracy. The hysteresis comparator eliminate the chattering effects when the output signal of Peak Detector changes rapidly around the threshold. The design is implemented in 0.18 mu m CMOS and occupies an active area of 0.41mm2. The power consumption of AGC is about 0.17mW at 1V supply voltage. The gain of PGA in the AGC loop ranges from 0dB to 40dB in 2dB step with gain error not more than 0.2dB. The integrated noise in the audio range (20 Hz similar to 20 kHz) is 2.28 mu VRMS when the gain is set at 40dB. The total harmonic distortion (THD) is below -70dB over the audio frequencies at 0.4-Vpp differential output.

Background: Age might affect the change in care needs in patients with hepatocellular carcinoma after treatment during their transition process from hospital to home. However, there have been no studies that focus on this. Objective: The aim of this study is to examine changes in unmet supportive care needs in young (G65 years old) and elderly (Q65 years old) groups of patients with hepatocellular carcinoma from before discharge to 2 months after discharge. Methods: A longitudinal prospective study design was used with recruited participants at a teaching hospital in Taiwan. Data were collected 3 times: within 3 days before discharge and at 1 and 2 months after discharge. A set of questionnaires was used to assess participants' levels of supportive care needs, symptom distress, anxiety, and depression. Results: A total of 104 patients completed the data collection process. Supportive care needs decreased monthly after discharge, with health system and information being the domain with the highest level of unmet needs in the 2 groups. The young group had a higher level of overall unmet needs before discharge, but they had a lower level of overall needs compared with the elderly group after 2 months of discharge. Conclusions: Age could be a significant potential factor to affect change in unmet needs during transition. Implications for Practice: Comprehensive assessment in care needs especially in the health system and information and physical and daily living domains before discharge is recommended to design personalized education programs before discharge.

The proportion of workers in their 50s, 60s, and 70s is larger than ever before. Current work-force trends indicate global increases in retirement ages and that many individuals are working until later ages than in decades past, and older people are applying for jobs and at later ages. Research to date on age discrimination in selection has focused primarily on disparate treatment or intentional discrimination. However, based on accumulated knowledge about age-related changes in cognitive and physical abilities as well as changes in personality and work motivation across the life course, we suggest that more attention be paid to the possibility of age-based subgroup differences on selection procedures, manifested as adverse impact and differential prediction. We provide recommendations to guide future human resource management research and practice. (C) 2016 Elsevier Inc. All rights reserved.

Objective: Patients over 60 years of age have higher mortality and morbidity after major liver resections. Nitric oxide (NO) derived from the catalytic activity of Nos2 plays a beneficial role in liver regeneration (LR) after partial hepatectomy (PH). In this experiment, we evaluated the effect of Nos2 knockout (KO) on LR in aged mice after PH. Materials and Methods: In this experimental study, 52 two-year-old Nos2 KO and 46 the same age wild-type (WT) C57BL/6J mice were subjected to 2/3 PH. Liver tissues were collected at 11 time points after PH. Mice survival ratio and liver coefficient (liver-weight/ body-weight) was calculated. Transcript and protein levels were estimated by reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR) and Western blot, respectively. Results: The aged Nos2 KO mice had lower survival ratio (P=0.039) and liver coefficient (P=0.002) at the termination phase. Nos2 transcript level was obviously increased after PH in WT mice and undetected in the Nos2 KO mice. During LR, the expression at the transcript level of Cyclin D1, Cyclin A2 and Cyclin B1 and protein expression level of proliferation marker Ki67 and proliferation-associated transcription factors JNK1, NF-kB and STAT3 were decreased or delayed. The expression of pro-apoptotic proteins, CAS-PASE3, CASPASE9 and BAX, was increased in the Nos2 KO mice. Conclusion: Decreased survival ratio and impaired LR in aged Nos2 KO mice is probably due to decreased liver cell proliferation and increased liver cell apoptosis.

The health benefits of playing football and the importance of exercise and social contact for healthy ageing are well established, but few older adults in the UK take enough exercise. Football is popular, flexible in format and draws players into engrossing, effortful and social exercise, but the physical demands of play at full speed may make it unsustainable for some older adults. Restricted to walking pace, will play still be engaging? Will health benefits be retained? Will physical demands remain manageable? This pilot study aims to investigate: (1) the experience of older adults playing walking football every week, is it sustainable and rewarding, (2) the intensity and locomotor pattern of walking football, (3) the scale and nature of walking football health benefits and (4) possible cognitive benefits of playing walking football through measures of processing speed, selective and divided attention and updating and inhibition components of executive function. 'Walking football' and 'waiting list' groups were compared before and after 12 weeks of one-hour per week football. Walking football was found to be engaging, sustainable for older adults and moderately intensive; however, selective health and cognitive benefits were not found from this brief intervention.

The question of specific properties of life compared to nonliving things accompanied biology throughout its history. At times this question generated major controversies with largely diverging opinions. Basically, mechanistic thinkers, who tried to understand organismic functions in terms of nonliving machines, were opposed by those who tried to describe specific properties or even special forces being active within living entities. As this question included the human body, these controversies always have been of special relevance to our self-image and also touched practical issues of medicine. During the second half of the twentieth century, it seemed to be resolved that organisms are explainable basically as physicochemical machines. Especially from the perspective of molecular biology, it seemed to be clear that organisms need to be explained solely by the chemical functions of their component parts, although some resistance to this view never ceased. This research program has been working quite successfully, so that science today knows a lot about the physiological and chemical processes within organisms. However, again new doubts arise questioning whether the mere continuation of this analytical approach will finally generate a fundamental understanding of living entities. At the beginning of the twenty-first century the quest for a new synthesis actually comes from analytical empiricists themselves. The hypothesis of the present paper is that empirical research has been developed far enough today, that it reveals by itself the materials and the prerequisites to understand more of the specific properties of life. Without recourse to mysterious forces, it is possible to generate answers to this age-old question, just using recent, empirically generated knowledge. This view does not contradict the results of reductionistic research, but rather grants them meaning within the context of organismic systems and also may increase their practical usefulness. Although several of these properties have been discussed before, different authors usually concentrated on a single one or some of them. The paper describes ten specific properties of living entities as they can be deduced from contemporary science. The aim is to demonstrate that the results of empirical research show both the necessity as well as the possibility of the development of a new conception of life to build a coherent understanding of organismic functions.

Important energy reductions can be achieved in the building sector by providing occupants with feedback about their energy-consumption levels. Recent studies link the success of energy-feedback methods to the level of occupant engagement with people in their social circles and the resulting peer pressure to conform to certain social norms. Despite promising results, the literature remains limited in scope to individual rather than groups of buildings. This has limited the design of feedback initiatives leveraging social connections that exist, or that can be induced, within and between buildings. The current paper addresses the identified gap by proposing a multilayer agent-based model that serves as a test bed to simulate and optimize feedback methods applied on any building stock (e.g.,community and city). Monte Carlo and sensitivity analyses show that connecting occupants of different buildings, while increasing their engagement with the feedback mechanism, can lead to energy reductions exceeding 10%. The findings confirm the role of social networks in energy-conservation diffusion, setting the stage for large-scale and socially engaging energy-conservation initiatives.

Extensively employed in reproductive science, the term fetal-maternal interface describes how maternal and fetal tissues interact in the womb to produce the transient placenta, purporting a theory of pregnancy where mother', fetus', and placenta' are already-separate entities. However, considerable scientific evidence supports a different theory, which is also elaborated in feminist and new materialist literatures. Informed by interviews with placenta scientists as well as secondary sources on placental immunology and the developmental origins of health and disease, I explore evidence not of interfacing during pregnancy, but of intra-action, or the mutual emergence of entities in simultaneous practices of differentiation and connection. I argue that attending to evidence that can be figured as intra-action enables us to recognize, account for, and attend to diffuse responsibilities for fetal-maternal outcomes that extend beyond mothers to the biosocial milieus of pregnancy. In reimaging the intra-action of placentas, a new understanding of what constitutes a healthy pregnancy' becomes possible.

Background: The collection of subgingival plaque samples with paper points is time-consuming and accident-sensitive. However, the collection of saliva is simple and contains pathogens of all intraoral surfaces. The aim of this study is to investigate whether a sampling strategy with mouthrinse (mouthrinse sample [MSP]; test) leads to results comparable with standard sampling method (multiple site test from the deepest pocket of each quadrant [MT4]; control). Methods: In 50 patients with periodontitis, subgingival plaque was sampled from the deepest pocket of each quadrant by using paper points and by gaining saliva with saline mouthrinse. Analysis was performed using a commercially available polymerase chain reaction test for 11 periodontal pathogens. Results: Detection frequency of Aggregatibacter actinomycetemcomitans (MT4/MSP: 42%/36%), Porphyromonas gingivalis (78%/66%), Tannerella forsythia (98%/84%), Treponema denticola (94%/74%), Parvimonas micra (86%/62%), Campylobacter rectus (90%/76%), Eubacterium nodatum (64%/30%), Prevotella intermedia (58%/54%), and Eikenella corrodens (90%/82%) was higher with MT4 than MSP. For Fusobacterium nucleatum (100%/100%), there was no difference between test and control. Only detection frequency of Capnocytophaga species (68%/74%) was higher with MSP than MT4. Differences were significant for P. gingivalis, T. forsythia, T. denticola, P. micra, C. rectus, and E. nodatum. Conclusions: There is no significant difference between MT4 and MSP for detection frequency of key pathogen A. actinomycetemcomitans. Key pathogens P. gingivalis, T. forsythia, T. denticola, P. micra, C. rectus, and E. nodatum show statistically higher detection frequencies with MT4.

This paper proposes a probabilistic optimization method that produces optimal bidding curves to be submitted by an aggregator to the day-ahead electricity market and the intraday market, considering the flexible demand of his customers (based in time dependent resources such as batteries and shiftable demand) and taking into account the possible imbalance costs as well as the uncertainty of forecasts (market prices, demand, and renewable energy sources (RES) generation). The optimization strategy aims to minimize the total cost of the traded energy over a whole day, taking into account the intertemporal constraints. The proposed formulation leads to the solution of different linear optimization problems, following the natural temporal sequence of electricity spot markets. Intertemporal constraints regarding time dependent resources are fulfilled through a scheduling process performed after the day-ahead market clearing. Each of the different problems is of moderate dimension and requires short computation times. The benefits of the proposed strategy are assessed comparing the payments done by an aggregator over a sample period of one year following different deterministic and probabilistic strategies. Results show that probabilistic strategy reports better benefits for aggregators participating in power markets.

This paper examines the association between the Great Recession and four measures of the risk for maternal child abuse and neglect: (1) maternal physical aggression; (2) maternal psychological aggression; (3) physical neglect by mothers; and (4) supervisory/exposure neglect by mothers. It draws on rich longitudinal data from the Fragile Families and Child Wellbeing Study, a longitudinal birth cohort study of families in 20 U.S. cities (N = 3177; 50% African American, 25% Hispanic; 22% non-Hispanic white; 3% other). The study collected information for the 9 year follow-up survey before, during, and after the Great Recession (2007-2010). Interview dates were linked to two macroeconomic measures of the Great Recession: the national Consumer Sentiment Index and the local unemployment rate. Also included are a wide range of socio-demographic controls, as well as city fixed effects and controls for prior parenting. Results indicate that the Great Recession was associated with increased risk of child abuse but decreased risk of child neglect. Households with social fathers present may have been particularly adversely affected. Results also indicate that economic uncertainty during the Great Recession, as measured by the Consumer Sentiment Index and the unemployment rate, had direct effects on the risk of abuse or neglect, which were not mediated by individual-level measures of economic hardship or poor mental health.

A growing body of research suggests that bipolar spectrum disorders (BSDs) are associated with high aggression. However, little research has prospectively examined how aggression may affect time to onset of hypomanic/manic versus major depressive episodes. In a longitudinal study, we tested the hypothesis that aggression would prospectively predict a shorter time to the onset of hypomanic/manic episodes and a longer time to the onset of major depressive episodes, based on the behavioral approach system theory of BSDs. Young adults (N=120) diagnosed with cyclothymia, bipolar II disorder, or bipolar disorder not otherwise specified were followed every 4 months for an average of 3.55 years. Participants completed measures of depressive and manic symptoms, family history of mood disorder, impulsivity, and aggression at baseline and were followed prospectively with semistructured diagnostic interview assessments of hypomanic/manic and major depressive episodes and treatment seeking for mood problems. Cox proportional hazard regression analyses indicated that overall, physical, and verbal aggression predicted a longer time to major depressive episode onset, even after controlling for baseline depressive and manic symptoms, family history of mood disorder, treatment seeking for mood problems, and impulsivity. Aggression, however, did not significantly predict time to onset of hypomanic/manic episodes, controlling for the same covariates. The findings suggest that approach-related behaviors may be utilized to delay the onset of major depressive episodes among people with BSDs.

Fipronil is an important member of the phenylpyrazole group of insecticides and is widely used for various crops and vegetables to control insects, thereby exposing birds, animals, and humans to fipronil. Currently, there is limited information on the effects of fipronil exposure in Japanese quail. Therefore, our aim was to assess the reproductive toxicological effects of fipronil in the Japanese quail in a 15-day gavage study and then its recovery over a period of 60 days. Fipronil-administration led to significant losses in both feed intake and body weight. Whereas, the gonadosomatic index was not affected, and histological changes observed in the testes were reversible, particularly by day 45 and day 60 of recovery. Cloacal gland atrophy, reduced foam quantity and a reduction in fertility, sexual and aggressive behaviors, and serum testosterone with elevated estradiol (E2) hormone levels were also observed. All these changes gradually reversed during various recovery periods. Further, alterations in hepatic vitellogenin (Vtg) and estrogen receptor alpha (ER alpha) gene expression, assessed by quantitative polymerase chain reaction, were also observed. Specifically, ER alpha 1 was induced after fipronil administration, while the Vtg transcript was elevated during both exposure and recovery periods. Our results showed that fipronil exposure has a profound negative influence on reproductive traits in the male Japanese quail and exhibits an estrogenic activity that can raise the incidence of infertility in males. Nevertheless, most of the changes could be reversed after a recovery period of 30-45 days. (C) 2016 Elsevier Ltd. All rights reserved.

Although previous studies in inmates, forensic and psychiatric samples suggest the relation between childhood trauma and suicide behavior as well as between childhood trauma and violent delinquency, the understanding of possible underlying mechanisms is still fragmentary. In a naturalistic study design, we tested if suicidal attempts and violent crimes are differently associated with adverse childhood experiences and levels of appetitive aggression in male forensic psychiatry inpatients. Adverse childhood experiences and appetitive aggression styles were collected by means of self-report measures, suicide attempts were taken from the medical history and violent crimes were appraised by official court records. The data were analyzed by the means of generalized linear models. Results revealed that appetitive aggression and adverse childhood experiences were significant predictors of suicide attempts, whereas violent crimes were associated solely with appetitive aggression. Suicide attempts and violent delinquency in forensic patients seem to be both positively associated with high levels of appetitive aggression, whereas their etiological pathways might differ with regard to adverse childhood experiences. Considering these interrelations to a greater extent might improve both diagnostics and treatment of forensic patients. (C) 2016 Elsevier Ireland Ltd. All rights reserved.

Sphingomyelin phosphodiesterase 3 (Smpd3), which encodes neutral sphingomyelinase 2 (nSMase2), is a key molecule for skeletal development as well as for the cytodifferentiation of odontoblasts and alveolar bone. However, the effects of nSMase2 on the cytodifferentiation of periodontal ligament (PDL) cells are still unclear. In this study, the authors analyzed the effects of Smpd3 on the cytodifferentiation of human PDL (HPDL) cells. The authors found that Smpd3 increases the mRNA expression of calcification-related genes, such as alkaline phosphatase (ALPase), type I collagen, osteopontin, Osterix (Osx), and runt-related transcription factor (Runx)-2 in HPDL cells. In contrast, GW4869, an inhibitor of nSMase2, clearly decreased the mRNA expression of ALPase, type I collagen, and osteocalcin in HPDL cells, suggesting that Smpd3 enhances HPDL cytodifferentiation. Next, the authors used exome sequencing to evaluate the genetic variants of Smpd3 in a Japanese population with aggressive periodontitis (AgP). Among 44 unrelated subjects, the authors identified a single nucleotide polymorphism (SNP), rs145616324, in Smpd3 as a putative genetic variant for AgP among Japanese people. Moreover, Smpd3 harboring this SNP did not increase the sphingomyelinase activity or mRNA expression of ALPase, type I collagen, osteopontin, Osx, or Runx2, suggesting that this SNP inhibits Smpd3 such that it has no effect on the cytodifferentiation of HPDL cells. These data suggest that Smpd3 plays a crucial role in maintaining the homeostasis of PDL tissue.

Background: Dendritic cells (DCs) form a key link between innate and adaptive immune responses. The aim of this study is to analyze presence and distribution of immature (im) and mature (m) DCs in gingival tissue samples obtained from patients diagnosed with aggressive periodontitis (AgP), chronic periodontitis (CP), and clinically healthy periodontium (control group). Methods: Gingival tissue samples obtained from patients with: 1) AgP (aged= 35 years); and 3) control group (aged >18 years) (n = 10 per group) were collected. Two-way analysis of variance and posterior Fisher least significant difference test were used to observe differences between the means of cells positively marked for imDC (S100, CD1a, and CD207) and mDC (CD208) immunomarkers. Results: imDCs were more numerous in AgP than CP and control groups, being statistically significant only for S100+ cells. Conversely, mDCs were visualized in higher numbers in CP than AgP and control groups (both P <0.05). Considering frequency of immunostained cells, the number of S100+ cells was greater than CD207+ and CD1a+ cells, followed by a lesser number of CD208+ cells, in all groups. Conclusions: Considering that the ability of DCs to regulate immunity is dependent on DC maturation, results suggest that predominance of imDCs appears to be involved in AgP pathogenesis, probably due to lack of ability to induce immune cell activation. Further studies are necessary to elucidate the role of DC maturation in regulating immune responses in periodontal disease.

Fragile x syndrome (FXS) is the most common form of inherited mental retardation disease. This is caused due to expansion of CGG triplet in 5'-untranslated region of fragile x mental retardation 1 (FMR-1) gene. In most of the cases, abnormally large size of the CGG repeat (>200) undergoes hypermethylation, which in turn silences the FMR-1 gene causing thereby complete lack of its protein product called fragile x mental retardation protein (FMRP). Lack of FMRP due to gene silencing or production of faulty protein due to point mutation in KH2 domain of FMRP alters the translational process in neurons and leads to expression of mental retardation phenotype on the patients. The FMRP is expressed ubiquitously in all tissues; however, it is predominantly expressed in neurons and testis. It possesses heterogeneity and is found in many isoforms due to alternative splicing of the FMR-1 transcript. Based on our data from the Western-, slot-, Northern blotting and immunohistochemical studies, we report here the down regulation of Fmr-1 gene and FMRP in mice brain in age-dependent manner. The present finding is important in respect to FMRP-dependent various brain functions i.e., learning, memory, cognition etc. that decrease with advancing age.

Background: Early life stress (ELS) and addiction are related to age-related diseases and telomere shortening. However, the role of telomere length (TL) in crack cocaine addiction remains unknown. The purpose of this study was to investigate the TL in a sample of crack cocaine dependent-women who reported an ELS history and in a community-based sample of elderly women as a reference group for senescence. Methods: This study included treatment seeking crack cocaine dependents women (n = 127) and elderly women without a psychiatric diagnosis (ELD, n = 49). The crack cocaine sample was divided in two groups according to their Childhood Trauma Questionnaire (CTQ) scores: presence of history of childhood abuse and neglect (CRACK-ELS) and absence of ELS history (CRACK). TL was assessed by T/S ratio obtained from peripheral blood DNA using quantitative PCR assay. esults: CRACK and CRACK-ELS subjects exhibited shortened TL in comparison to the ELD group, despite their younger age. Among crack cocaine sample, CRACK-ELS group had significantly shorter telomeres than the CRACK group. Correlation analysis within crack cocaine group indicated that TL was negatively correlated with emotional abuse scores. Conclusions: These results support previous findings associating telomere shortening with both ELS and drug addiction. This study suggests new evidence of a distinct biological phenotype for drug-dependent women with ELS. The results support the biological senescence hypothesis underpinning ELS experience.

Significance: With the growing population of baby boomers, there is a great need to determine the effects of advanced age on the function of the immune system. Recent Advances: It is universally accepted that advanced age is associated with a chronic low-grade inflammatory state that is referred to as inflamm-aging, which alters the function of both immune and nonimmune cells. Mononuclear phagocytes play a central role in both the initiation and resolution of inflammation in multiple organ systems and exhibit marked changes in phenotype and function in response to environmental cues, including the low levels of pro-inflammatory mediators seen in the aged. Critical Issues: Although we know a great deal about the function of immune cells in young adults and there is a growing body of literature focusing on aging of the adaptive immune system, much less is known about the impact of age on innate immunity and the critical role of the mononuclear phagocytes in this process. Future Directions: In this article, there is a focus on the tissue-specific monocyte and macrophage subsets and how they are altered in the aged milieu, with the hope that this compilation of observations will spark an expansion of research in the field.

Rationale: Leukocyte telomere length (LTL) is a biological marker of aging, and shorter LTL is associated with adverse cardiovascular outcomes. Reduced regenerative capacity has been proposed as a mechanism. Bone marrow-derived circulating progenitor cells are involved in tissue repair and regeneration. Objective: Main objective of this study was to examine the relationship between LTL and progenitor cells and their impact on adverse cardiovascular outcomes. Methods and Results: We measured LTL by quantitative polymerase chain reaction in 566 outpatients (age: 63 +/- 9 years; 76% men) with coronary artery disease. Circulating progenitor cells were enumerated by flow cytometry. After adjustment for age, sex, race, body mass index, smoking status, and previous myocardial infarction, a shorter LTL was associated with a lower CD34+ cell count: for each 10% shorter LTL, CD34+ levels were 5.2% lower (P< 0.001). After adjustment for the aforementioned factors, both short LTL (< Q1) and low CD34+ levels (< Q1) predicted adverse cardiovascular outcomes (death, myocardial infarction, coronary revascularization, or cerebrovascular events) independently of each other, with a hazard ratio of 1.8 and 95% confidence interval of 1.1 to 2.0, and a hazard ratio of 2.1 and 95% confidence interval of 1.3 to 3.0, respectively, comparing Q1 to Q2-4. Patients who had both short LTL (< Q1) and low CD34+ cell count (< Q1) had the greatest risk of adverse outcomes (hazard ratio = 3.5; 95% confidence interval, 1.7-7.1). Conclusions: Although shorter LTL is associated with decreased regenerative capacity, both LTL and circulating progenitor cell levels are independent and additive predictors of adverse cardiovascular outcomes in coronary artery disease patients. Our results suggest that both biological aging and reduced regenerative capacity contribute to cardiovascular events, independent of conventional risk factors.

One of the most significant reliability issues in switching-mode power supplies is electrolytic capacitor degradation caused by aging. This paper proposes an output voltage transient analysis method to detect capacitor wear-out at the output stage of a step-down dc-dc converter. Changes in the converter output voltage dynamics are evaluated by analyzing the output voltage step response with respect to a decrease in the capacitance. The sensitivity of the method is assessed with respect to parameter variations using an equivalent main circuit model. The feasibility of the presented method is verified by experimental tests using a converter prototype. The results show that the presented method is practical and adequate for detecting capacitor degradation in various operating conditions.

The detection of degradations and resulting failures in electronic components/systems is of paramount importance for complex industrial applications including nuclear power reactors, aerospace, automotive, and space applications. There is an increasing acceptance of the importance of detection of failures and degradations in electronic components and of the prospect of system-level health monitoring to make a key contribution to detecting and predicting any impending failures. This paper describes a parametric system identification-based health-monitoring method for detecting aging degradations of passive components in switch-mode power converters (SMPCs). A nonparametric system response is identified by perturbing the system with an optimized multitone sinusoidal signal of the order of mVs. The parametric system model is estimated from nonparametric system response using recursive weighted least-square (WLS) algorithm. Finally, the power-stage component values, including their parasitics, are extracted from numerator and denominator coefficients based on the assumed Laplace system model. These extracted component values provide direct diagnostic information of any degradation or anomalies in the components and the system. A proof of concept is initially verified on a simple point-of-load (POL) converter but the same methodology can be applied to other topologies of SMPC.

Background-Circulating levels of chemerin are significantly higher in hypertensive patients and positively correlate with blood pressure. Chemerin activates chemokine-like receptor 1 (CMKLR1 or ChemR23) and is proposed to activate the "orphan" G protein-coupled receptor 1 (GPR1), which has been linked with hypertension. Our aim was to localize chemerin. CMKLR1, and GPR1 in the human vasculature and determine whether 1 or both of these receptors mediate vasoconstriction. Methods and Results-Using immunohistochemistry and molecular biology in conduit arteries and veins and resistance vessels, we localized chemerin to endothelium, smooth muscle, and adventitia and found that CMKLR1 and GPR1 were widely expressed in smooth muscle. C9 (chemerin149-157) contracted human saphenous vein (pD(2)=7.30 +/- 0.31) and resistance arteries (pD(2)=7.05 +/- 0.54) and increased blood pressure in rats by 9.1 +/- 1.0 mm Hg at 200 nmol. Crucially, these in vitro and in vivo vascular actions were blocked by CCX832, which we confirmed to be highly selective for CMKLR1 over GPR1. C9 inhibited cAMP accumulation in human aortic smooth muscle cells and preconstricted rat aorta, consistent with the observed vasoconstrictor action. Downstream signaling was explored further and, compared to chemerin. C9 showed a bias factor=approximate to 5000 for the Gi protein pathway, suggesting that CMKLR1 exhibits biased agonism. Conclusions-Our data suggest that chemerin acts at CMKLR1, but not GPR1, to increase blood pressure. Chemerin has an established detrimental role in metabolic syndrome, and these direct vascular actions may contribute to hypertension, an additional risk factor for cardiovascular disease. This study provides proof of principle for the therapeutic potential of selective CMKLR1 antagonists.

Biofilm formation usually increases antimicrobial resistance capacity of Staphylococcus aureus, which poses considerable challenges to successful eradication of staphylococcal infections. Very little is known about the biofilm-forming capacity and antibiotic resistance pattern of dominant S. aureus clonal lineages in China. In this study, the disk diffusion method and the microtiter plate assay were, respectively, performed to determine the antibiotic resistance and biofilm-forming capacity of 84 different S. aureus isolates belonging to 10 dominant clonal lineages in China. It was shown that isolates of different clonal lineages had obvious variations in biofilm-forming capacity. Resistance to individual antibacterial agents was most frequently observed to erythromycin (72.6%) and azithromycin (72.6%). Then, all tested isolates were further screened for the presence of 16 resistance genes by polymerase chain reaction (PCR), and no significant correlation was found between clonal lineage and the distribution of resistance genes. Overall, our results indicate that biofilm producers of S. aureus have a greater likelihood to carry more antibiotic resistance genes than non-biofilm producers (p<.01), further implying that biofilm may promote the dissemination of antibiotic resistance determinants. Practical applicationsStaphylococcus aureus is the leading cause of nosocomial infections and often associated with food poisoning worldwide. Biofilm formation of S. aureus influences the efficacy of antimicrobial therapy and promotes the persistence of infections; however, the knowledge about biofilm formation capacity of isolates belonging to different clonal lineages is little. Therefore, this study on biofilm formation capacity and antibiotic resistance pattern of dominant S. aureus clonal lineages could help to fix this information gap.

Gene editing technologies are a group of recent innovations in plant breeding using molecular biology, which have in common the capability of introducing a site-directed mutation or deletion in the genome. The first cases of crops improved with these technologies are approaching the market; this has raised an international debate regarding if they should be regulated as genetically modified crops or just as another form of mutagenesis under conventional breeding. This dilemma for policymakers not only entails issues pertaining safety information and legal/regulatory definitions. It also demands borrowing tools developed in the field of social studies of science and technology, as an additional basis for sound decision making.

BACKGROUNDWeeds can be a greater constraint to crop production than animal pests and pathogens. Pre-emergence herbicides are crucial in many cropping systems to control weeds that have evolved resistance to selective post-emergence herbicides. In this study we assessed the potential to evolve resistance to the pre-emergence herbicides prosulfocarb + S-metolachlor or pyroxasulfone in 50 individual field Lolium rigidum populations collected in a random survey in Western Australia prior to commercialisation of these pre-emergence herbicides. RESULTSThis study shows for the first time that in randomly collected L. rigidum field populations the selection with either prosulfocarb + S-metolachlor or pyroxasulfone can result in concomitant evolution of resistance to both prosulfocarb + S-metolachlor and pyroxasulfone after three generations. CONCLUSIONSIn the major weed L. rigidum, traits conferring resistance to new herbicides can be present before herbicide commercialisation. Proactive and multidisciplinary research (evolutionary ecology, modelling and molecular biology) is required to detect and analyse resistant populations before they can appear in the field. Several studies show that evolved cross-resistance in weeds is complex and often unpredictable. Thus, long-term management of cross-resistant weeds must be achieved through heterogeneity of selection by effective chemical, cultural and physical weed control strategies that can delay herbicide resistance evolution.

The Arabidopsis thaliana bZIP60 (AtbZIP60) transcription factor regulates stress signaling. However, its molecular mechanism remains to be elucidated. In this investigation, cell suspension cultures of two different plant species rice (Oryza sativa L.) and white pine (Pinus strobes L.) were transformed using Agrobacterium tumefaciens strain LBA4404 harboring pBI-AtZIP60. Integration of the AtbZIP60 gene into the genome of rice and white pine has been confirmed by polymerase chain reaction (PCR), southern blotting, and northern blotting analyses. Six transgenic cell lines from O. sativa and three transgenic cell lines from P. strobus were used to analyze the salt, drought, and cold tolerance conferred by the overexpression of the AtbZIP60 gene. Our results demonstrated that expression of the AtbZIP60 gene enhanced salt, drought, and cold tolerance in rice and white pine transgenic cell lines. In rice, transcription factor AtbZIP60 increased expression of Ca2+-dependent protein kinase genes OsCPK6, OsCPK9, OsCPK10, OsCPK19, OsCPK25, and OsCPK26 under treatment of salt, drought, and cold. These results demonstrated that overexpression of the AtbZIP60 gene in transgenic cell lines improved salt, drought, and cold stress tolerances by regulating expression of Ca2+-dependent protein kinase genes. Overexpression of the AtbZIP60 gene could be an alternative choice for engineering plant abiotic stress tolerance.

An efficient transformation system for Chinese cabbage cotyledon explants was developed using Agrobacterium tumefaciens strains LBA4404 harbouring the plasmid pMOG411 and the plasmid pBin Omega SCK respectively. Various factors affecting the transformation efficiency and subsequent regeneration were identified. The age of seedlings, growth conditions and status of Agrobacterium suspension, preculture of explants, cocultivation time, ratio between Agrobacterium and explants, acetosyringone and concentration of kanamycin had a significant influence on transformation frequency and plant regeneration. The presences of the antibacterial peptide gene and the cowpea trypsin inhibitor gene in those selected shoots in kanamycin medium were confirmed by PCR, Southern blotting and Northern blotting, The frequency of regeneration from cotyledons was analyzed in eight parental lines of Chinese cabbage and five lines were suitable for obtaining transformed plants, among which Qingmaye C and Qingmaye D were more responsive than other lines.

'Mexican' lime (Citrus aurantifolia Swingle) was transformed with constructs that contained chimeric promoter-gus gene fusions of phloem-specific rolC promoter of Agrobacterium rhizogenes, Arabidopsis thaliana sucrose-H+ symporter (AtSUC2) gene promoter of Arabidopsis thaliana, rice tungro bacilliform virus (RTBV) promoter and sucrose synthase l (RSs1) gene promoter of Oryza sativa (rice). Histochemical beta-glucuronidase (GUS) analysis revealed vascular-specific expression of the GUS protein in citrus. The RTBV promoter was the most efficient promoter in this study while the RSs1 promoter could drive low levels of gus gene expression in citrus. These results were further validated by reverse transcription real-time polymerase chain reaction and northern blotting. Southern blot analysis confirmed stable transgene integration, which ranged from a single insertion to four copies per genome. The use of phloem-specific promoters in citrus will allow targeted transgene expression of antibacterial constructs designed to battle huanglongbing disease (HLB or citrus greening disease), associated with a phloem-limited Gram-negative bacterium.

To improve the transformation efficiency of wheat (Triticum aestivum L.) mediated by Agrobacterium tumefaciens, we explored the possibility of employing the basal portion of wheat seedling (shoot apical meristem) as the explants. Three genotypes of wheat were transformed by A. tumefaciens carrying beta-1, 3-glucanase gene. After vernalization, the seeds to be transformed were germinated. When these seedlings grew up to 2 similar to 5 cm, their coleoptile and half of the cotyledon were cut out, and the basal portions were infected by A. tumefaciens. A total 27 T-0 transgenic plants were obtained, and the average transformation efficiency was as high as 9.82%. Evident segregation occurred in some of the T-1 plants, as was indicated by PCR and Southern blotting analysis. Investigation of the T-2 plants revealed that some transformed plants had higher resistance to powdery mildew than the controls. Northern blotting revealed that beta-1, 3-glucanase gene was normally expressed in the T-2 plants, which showed an increased resistance to powdery mildew. The results above indicate that the exogenous gene has been successfully integrated into the genome of wheat, transmitted and expressed in the transgenic progeny. From all the results above, it can be concluded that Agrobacterium inoculum to the basal portion of wheat seedling is a highly efficient and dependable transformation method. It can be developed into a practicable method for transfer of target gene into wheat.

Constantly elevated temperatures cause an array of physio-biochemical changes in tomato (Lycopersicum esculentum Mill.) which make the fruit ripen quickly and up to 50 % yield loss. The development of tomato cultivars, using genetic engineering approaches which delay ripening, offers a new way to keep tomatoes healthy under heat stress. Over-expression of small heat shock protein gene, viscosity 1 (vis 1) plays a role in increasing juice viscosity, early ripening and tissue soften which emphasizes the importance of this gene in premature ripening. The aim of this work was therefore to develop a useful system for silencing the vis1 gene using small interfering RNA strategy. Agrobacterium strain GV3101 harbouring the binary vector pICBV19 containing the gus and bar genes was used to adapt the transformation process in this study. The primers were designed to amplified the first exon of the vis 1 gene and the amplified fragment was used for cloning into the pFGC5941 at XhoI/NcoI site at sense orientation then additional fragment was subsequently cloned at BamHI/XbaI to form sense/antisense cloned fragment interrupted by the CHSA-intron Agrobacterium strain LBA4404 with the binary vector pFGC5941 which harbors vis1 gene under the control of the 35S promoter containing bar gene under the control of a mannopine synthase 2'(Mas2') as selectable marker, was used to reduce the expression of vis1 gene in fruit. Polymerase chain reaction (PCR), RT-PCR and northern blotting analysis were applied to detect putative transgenic plants. Significantly, silencing of vis 1 gene was potently occur and new transgenic tomato cultivars were produced with enhanced ripening qualities for recommendation for growing under heat stress.

To induce virus resistance in tobacco and rice we constructed hairpin RNA expression system harbouring inverted repeat fragments of coat protein cDNA of Potato virus Y (PVY) or Rice stripe virus (RSV). These structures were driven by three promoters [cauliflower mosaic virus 35S (CaMV 35S), polyubiqutin gene of maize (Ubi), and Pharbitis nil leucine zipper gene (PNZIP)] which have different tissue-specific activity. PVY resistance ratios were 65.18, 24.33 and 83.54 % in transgenic tobacco plants harboring p35S-PVY, pUbi-PVY and pPNZIP-PVY. RSV resistance was 16.21, 28.61 and 29.33 % in transgenic rice plants harboring p35S-RSV, pUbi-RSV and pPNZIP-RSV. Northern blotting and GUS assay demonstrated that virus resistance levels were related to promoter activity. Therefore, choice of the more effective and tissue-specific promoter to reinforce transcription of hpRNAs will favour the cultivation of highly virusresistant transgenic plants.

Potato is one of the main targets for genetic improvement by gene transfer. The aim of the present study was to establish a robust protocol for the genetic transformation of three dihaploid and four economically important cultivars of potato using Agrobacterium tumefaciens carrying the in vivo screenable reporter gene for green fluorescent protein (gfp) and the marker gene for neomycin phosphotransferase (nptII). Stem and leaf explants were used for transformation by Agrobacterium tumefaciens strain LBA4404 carrying the binary vector pHB2892. Kanamycin selection, visual screening of GFP by epifluorescent microscopy, PCR amplification of nptII and gfp genes, as well as RT-PCR and Southern blotting of gfp and Northern blotting of nptII, were used for transgenic plant selection, identification and analysis. Genetic transformation was optimized for the best performing genotypes with a mean number of shoots expressing gfp per explant of 13 and 2 (dihaploid line 178/10 and cv. 'Baltica', respectively). The nptII marker and gfp reporter genes permitted selection and excellent visual screening of transgenic tissues and plants. They also revealed the effects of antibiotic selection on organogenesis and transformation frequency, and the identification of escapes and chimeras in all potato genotypes. Silencing of the gfp transgene that may represent site-specific inactivation during cell differentiation, occurred in some transgenic shoots of tetraploid cultivars and in specific chimeric clones of the dihaploid line 178/10. The regeneration of escapes could be attributed to either the protection of non-transformed cells by neighbouring transgenic cells, or the persistence of Agrobacterium cells in plant tissues after co-cultivation.

The Arabidopsis thaliana bZIP60 (AtbZIP60) transcription factor regulates stress signaling, pathogen defense, and flower development. However, molecular mechanism involved in plant salt tolerance via overexpression of transcription factor AtbZIP60 is elusive. In this investigation, cell suspension cultures of four different plant species cotton (Gossypium hirsutum L.), Virginia pine (Pinus virginiana L.), white pine (Pinus strobus L.), and Arabidopsis (Arabidopsis thaliana) were transformed via Agrobacterium tumefaciens LBA4404 harboring pBI-AtZIP60. Integration of AtbZIP60 into the genome of G. hirsutum, P. virginiana, P. strobes, and A. thaliana has been confirmed by polymerase chain reaction, Southern blotting, and northern blotting analyses. Six transgenic cell lines from each of four species were used to analyze the salt tolerance conferred by the overexpression of AtbZIP60. Our results demonstrated that expression of AtbZIP60 enhanced salt tolerance of transgenic cells in all transgenic lines, and that improved salt tolerance was associated with increased activities of both H+-ATPase and acid phosphatase and decreased lipid peroxidation (thiobarbituric acid reactive substances) in transgenic cell lines from cotton (Gh1, Gh2, Gh3, Gh4, Gh5, and Gh6), Virginia pine (Pv1, Pv2, Pv3, Pv4, Pv5, and Pv6), white pine (Ps1, Ps2, Ps3, Ps4, Ps5, and Ps6), and Arabidopsis (At1, At2, At3, At4, At5, and At6). This investigation demonstrated that the expression of AtbZIP60 gene in transgenic cell lines reduced salt-induced oxidative damage by increasing the activities of both H+-ATPase and acid phosphatase, and that the overexpression of AtbZIP60 gene could be valuable for engineering plant salt tolerance.

The Arabidopsis thaliana bZIP60 (AtbZIP60) transcription factor regulates stress signaling. However, its involvement in plant salt tolerance is not fully understood. In this investigation, cell suspension cultures of three different plant species: tobacco (Nicotiana tabacum), rice (Oryza sativa L.), and slash pine (Pinus elliottii Engelm.) were transformed via Agrobacterium tumefaciens LBA4404 harboring pBI-AtbZIP60deltaC. Integration of AtbZIP60deltaC into the genome of tobacco, rice, or slash pine has been confirmed by polymerase chain reaction, Southern blotting, and Northern blotting analyses. Six transgenic cell lines from each of three species were used to analyze the salt tolerance conferred by the overexpression of AtbZIP60deltaC. Our results demonstrated that expression of AtbZIP60deltaC enhanced salt tolerance of transgenic cells in all transgenic lines and that improved salt tolerance was associated with increased activities of both ascorbate peroxidase and superoxide dismutase, and decreased lipid peroxidation (thiobarbituric acid reactive substances). This investigation has demonstrated that the expression of AtbZIP60deltaC gene in transgenic cell lines attenuated salt-induced oxidative damage by increasing the activities of antioxidant enzymes and the overexpression of AtbZIP60deltaC gene could be an alternative choice for engineering plant salt tolerance.

The aim of the present study was to produce marker-free transgenic potato resistant to PVY by using a construct generating self-complementary hairpin RNAs. The method has two steps: 1) establishing a robust protocol for the genetic transformation of economically important cultivars of potato by using gfp and nptII genes; 2) applying the protocol for the transfer of marker-free hairpin construct and analysis of transgenic plants by PCR. In the first step internodes were transformed by Agrobacterium tumefaciens LBA4404 with pH82892 construct. Kanamycin, visual screening of GFP, PCR of nptII and gfp as well as RT-PCR and Southern blotting of gfp and Northern blotting of nptII were used for transgenic plant selection. Good regeneration and transformation efficiency were obtained for the cvs. Baltica and Desiree while the cvs. Agave and Delikat showed lower figures. In the second step A. tumefaciens with construct: 35SCaMV enhancer and promoter, two repeated inverted PVY-CP sequences separated by an intron and pAnos terminator was used Regenerated plants without selection, were analysed by PCR using primers in the: 35S promoter, promoter and hairpin region, or in both repeated PVY-CP sequences. A large number of transgenic plants were identified for the most responsive cv. Baltica (17 out of 33) and Desiree (23 out of 66), but only I for the cv. Agave (out of 3) and none for the cv. Delikat. This simple two-step strategy might be applied to generate marker-free transgenic plants in other cvs. or plant species.

The disciplinary structure of research on complex problems related to human activities is supported by the fundaments of the social, life, and hard sciences. In this work, we looked at the development of scientific research in the field of biofuels, as a sustainable source of energy, searching for references regarding its scientific roots and social relevance. Scientific communications on biofuels published between 1998 and 2007 were analyzed using a combination of bibliometric methods and text mining techniques. This field of research was characterized as interdisciplinary, with marked social relevance. Our bibliometric analysis shows that, in this research subject, 132 different, interacting fields of knowledge overlap, with dominance of Chemistry, Engineering and Agricultural Sciences. Through the use of text mining techniques, this field was configured into three groups of Disciplinary Dimensions. The first and most influential group includes the Agricultural Sciences, Social Sciences, and Environmental Sciences. The second group, which gives the field its technological basis, includes Chemistry, Engineering, and Microbiology. The third group includes disciplines with emerging involvement in the field of biofuels: Biology and Biochemistry, Animal and Plant Sciences, Molecular Biology and Genetics, Economics, Material Sciences, Nanosciences and Nanotechnology, Geosciences, Physics, Humanities, Multidisciplinary Sciences, Mathematics, and Computer Sciences. This study suggests that the first group of Disciplinary Dimensions conforms to the elements that socially validate the progress of research in the field of biofuels. This study also proposes a metric that can be used to measure the interdisciplinarity and the social framing of any other research field.

The transport sector is one of the main sources of greenhouse gases, adding in Spain near a quarter of the total national emissions, the majority in road transport. Therefore, road contribution to climate change should be mitigated to achieve the proposed goals in the fight against climate change. Policies and strategies suggest several preventive mitigation options, but have paid little attention to compensatory mitigation. We have conducted a theoretical case study in a Spanish province, Segovia, estimating the carbon dioxide emissions in the road network between 2015 and 2050, and analysing different compensation possibilities through conservation agriculture, agroforestry, afforestation and hedgerow plantation. We have calculated carbon sequestration in the reference period and costs per tonne for each option, estimating the budget range of offsetting road carbon emission, and funding possibilities, especially through fuel taxes. The paper demonstrates that offsetting carbon emissions produced by roads in this area is technically possible and highly desirable, unifying carbon sequestration, biodiversity improvement and rural development. The main challenge is funding, which depends largely on the political will and the awareness of the citizens. (C) 2017 Elsevier B.V. All rights reserved.

African horse sickness (AHS) is a fatal disease of equids relevant to the global equine industry. Detection of AHS virus (AHSV) during outbreaks has become more rapid and efficient with the advent of group specific reverse transcriptase quantitative polymerase chain reaction (GS RT-qPCR) assays to detect AHSV nucleic acid. Use of GS RT-qPCR together with recently described type specific (TS RT-qPCR) assays cannot only expedite diagnosis of AHS but also facilitate further evaluation of the dynamics of AHSV infection in the equine host. A potential limitation to the application of these assays is that they detect viral nucleic acid originating from any AHS live attenuated vaccine (LAV), which is the vaccine type routinely administered to horses in South Africa. The aim of this study was to contrast the dynamics and duration of the RNAaemia to the serological responses of horses following immunization with a commercial polyvalent AHSV-LAV using GS and TS RT-qPCR assays and serum neutralisation tests. The results of the study showed extended RNAemia in vaccinated horses, and that more horses tested positive on GS RT-qPCR with lower Cq values after receiving the AHSV-LAV containing types 1, 3 and 4 prior to the vaccine containing types 2, 6, 7 and 8, rather than when the vaccine combinations were reversed. Furthermore, lower Cq values were obtained when vaccines were administered 4 weeks apart as compared with a longer interval or 12 weeks apart. These findings are of particular relevance in regions where AHSV-LAVs are used as the use of these vaccines may complicate the accurate interpretation of diagnostic testing results.

BACKGROUND The time of progression towards AIDS can vary greatly among seropositive patients, and may be associated with host genetic variation. The NR1I2 (PXR) gene, a ligand-activated transcription factor, regulates the transcription immune pathway genes and can therefore be targets of viral replication mechanisms influencing time of progression to AIDS. OBJECTIVE To verify the association of single nucleotide polymorphisms (SNPs) rs3814057, rs6785049, rs7643645, and rs2461817 in the NR1I2 (PXR) gene with progression to AIDS in HIV-1 infected patients. METHODS Blood samples were obtained from 96 HIV-1 positive individuals following informed consent. DNA was isolated and genotyped through real time polymerase chain reaction (PCR) for the presence of SNPs in the NR1I2. Questionnaires on socio-demographic features and behaviors were answered and time of progression to AIDS was estimated based on medical chart analysis. FINDINGS Patients with the GG genotype for rs7643645 were shown to be related with a more rapid disease progression when compared to GA and AA genotypes. This result was maintained by the Multivariate Cox Regression considering sex, ethnicity, and presence of HLA-B*57, HLA-B*27, and CCR5del32 polymorphisms. MAIN CONCLUSIONS Recent studies reported the expression of the nuclear receptors in T-Lymphocytes, suggesting their possible role in the immune response. In addition, nuclear receptors have been shown to inhibit the HIV replication, although no such mechanism has been thoroughly elucidated to date. This is the first time an association between NR1I2 polymorphism and time of progression to AIDS is reported and supports an apparent relationship between the gene in the immune response and identifies another genetic factor influencing AIDS progression.

Background: The presence of gross deletions in the human immunodeficiency virus nef gene (g Delta nef) is associated with long-term nonprogression of infected patients. Here, we investigated how quickly genetic defects in the nef gene are associated with Korean Red Ginseng (KRG) intake in 10 long-term slow progressors. Methods: This study was divided into three phases over a 20-yr period; baseline, KRG intake alone, and KRG plus highly active antiretroviral therapy (ART). nef gene amplicons were obtained using reverse transcription polymerase chain reaction (PCR) and nested PCR from 10 long-term slow progressors (n = 1,396), and nested PCR from 36 control patients (n = 198), and 28 ART patients (n = 157), and these were then sequenced. The proportion of g Delta nef, premature stop codons, and not in-frame insertion or deletion of a nucleotide was compared between three phases, control, and ART patients. Results: The proportion of defective nef genes was significantly higher in on-KRG patients (15.6%) than in baseline (5.7%), control (5.6%), on-KRG plus ART phase (7.8%), and on-ART patients (6.6%; p < 0.01). Small in-frame deletions or insertions were significantly more frequent among patients treated with KRG alone compared with controls (p < 0.01). Significantly fewer instances of genetic defects were detected in samples taken during the KRG plus ART phase (7.8%; p < 0.01). The earliest defects detected were g Delta nef and small in-frame deletions after 7 mo and 67 mo of KRG intake, respectively. Conclusion: KRG treatment might induce genetic defects in the nef gene. This report provides new insight into the importance of genetic defects in the pathogenesis of AIDS. (C) 2017 The Korean Society of Ginseng, Published by Elsevier Korea LLC.

Background: CSF PCR is the standard diagnostic technique used in resource-rich settings to detect pathogens of the CNS infection. However, it is not currently used for routine CSF testing in China. Knowledge of CNS opportunistic infections among people living with HIV in China is limited. Methods: Intensive cerebrospiral fluid (CSF) testing was performed to evaluate for bacterial, viral and fungal etiologies. Pathogen-specific primers were used to detect DNA from cytomegalovirus (CMV), herpes simplex virus (HSV), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), human herpesvirus 6 (HHV-6) and John Cunningham virus (JCV) via real-time polymerase chain reaction (PCR). Results: Cryptococcal meningitis accounted for 63.0% (34 of 54) of all causes of meningitis, 13.0% (7/54) for TB, 9.3% (5/54) for Toxoplasma gondii. Of 54 samples sent for viral PCR, 31.5% (17/54) were positive, 12 (22.2%) for CMV, 2 (3.7%) for VZV, 1 (1.9%) for EBV, 1 (1.9%) for HHV-6 and 1 (1.9%) for JCV. No patient was positive for HSV. Pathogen-based treatment and high GCS score tended to have a lower mortality rate, whereas patients with multiple pathogens infection, seizures or intracranial hypertension showed higher odds of death. Conclusion: CNS OIs are frequent and multiple pathogens often coexist in CSF. Cryptococcal meningitis is the most prevalent CNS disorders among AIDS. The utility of molecular diagnostics for pathogen identification combined with the knowledge provided by the investigation may improve the diagnosis of AIDS related OIs in resource-limited developing countries, but the cost-efficacy remains to be further evaluated.

Three novel differential amplifier topologies using double gate a-IGZO TFTs on flexible substrate are presented in this paper. The designs exploit positive feedback and a load with self-biased top gate to achieve the highest static gain in single stage a-IGZO amplifiers reported to date. After fabrication, the three amplifiers exhibit respectively a static gain of 14 dB, 21.5 dB, and 30 dB, with a bandwidth of 2 kHz, 400 Hz, and 150 Hz. Also, for each circuit the input referred noise has been measured to be 420 mu V-rms, 195 mu V-rms, and 146 mu V-rms, respectively. Based on these results, the a-IGZO amplifier providing the highest gain is suitable as front-end for heart rate measurements and, with some further optimization verified in simulation, can also be used for other bio-potential applications, like electro hysterogram and electro cardiogram.

Typical variable air volume (VAV) terminals spend the majority of time at their minimum airflow set points. These are often higher than the minimum ventilation requirements defined by code, resulting in excess energy use and a risk of over-cooling the spaces. We developed and tested a time-averaged ventilation (TAV) control strategy in an institutional building on the UC Berkeley campus to address this issue. Whenever a zone does not require cooling, TAV alternates the VAV damper between partially open and fully closed so that the average airflow matches a predefined ventilation setpoint. Compared to the existing, base case scenario using single-max VAV logic, this strategy reduced the mean zone airflow fraction from 0.44 to 0.27 during the intervention period. The corresponding reductions in average heating, cooling, and fan power were 41%, 23%, and 15% respectively. In addition to being programmed directly in a native control system, TAV may be applied via sMAP as a low-cost retrofit strategy in any building that has a BACnet network and direct digital control (DDC) to each VAV terminal.

Numerous studies have reported an association between fine particulate matter (PM2.5) and human health. Often these relationships are influenced by environmental factor that varies spatially and/or temporally. To our knowledge, there are no studies in Canada that have considered energy generation and fuel sales as PM2.5 effects modifiers. Determining exposure and disease-specific risk factors over space and time is crucial for disease prevention and control. In this study, we evaluated the association of PM2.5 with diabetes, asthma, and High Blood Pressure (HBP) incidence in Canada. Then we explored the impact of the energy generation and fuel sales on association changes. We fit an age-period-cohort as the study design, and We applied an over-dispersed Poisson regression model to estimate the risk. We conducted a sensitivity analysis to explore the impact of variation in clean energy rates and fuel sales on outcomes changes. The study included 117 health regions in Canada between 2007 and 2014. Our findings showed strong association of PM2.5 with diabetes, asthma, and HBP incidence. A two-year increase of 10 mu g/m(3) in PM2.5 was associated with an increased risk of 534% (95% CI: 2.28%; 12.53%) in diabetes incidence, 2.24% (95% CI: 0.93%; 538%) in asthma incidence, and 8.29% (95% CI: 3.44%; 19.98%) in HBP incidence. Our sensitivity analysis findings suggest higher risks of diabetes, asthma and HBP incidence when there is low clean energy generation. On the other hand, we found lower risk when we considered high rate of clean energy generation. For example, considering only diabetes incidence, we found that the risk in health regions with low rates of clean electricity is approximately 700% higher than the risk in health regions with high rates of clean electricity. Furthermore, our analysis suggested that the risk in regions with low fuel sales is 66% lower than the risk is health regions with low rates of clean electricity. Our study provides support for the creation of effective environmental health public policies that take into account the risk factors present in Canadians health regions. (C) 2017 Elsevier B.V.

Effectively analyzing and then treating energy-related air pollution requires examining every factor, from the pollution source to the end of treatment. This paper applies index decomposition analysis and a whole process treatment perspective to identify the factors facilitating air pollution reduction across three stages: source prevention, process control, and end-of-pipe treatment. Empirical research using data from China's Jiangsu Province and its 13 cities reveals differences in local approaches to pollution prevention. At the provincial level, end-of-pipe treatment remains the primary approach to control air pollution emissions, indicating that the pattern of "pollute first, govern later" has not yet been fundamentally reversed. At the city level, 13 cities can be divided into four types, based on their approach to air pollution treatment: the leading type, process-dependent type, end-dependent type, and lagging type. Of these, 7 cities are using multiple control approaches, reflecting the comprehensive effect of whole process treatment. The Jiangsu Province should consider further strengthening effective whole process air pollution treatment models, by transitioning to pollution control, adjusting industrial structure, promoting technological progress, and consuming clean energy.

The paper presents the design and some results for an experimental platform aimed to control the air pressure inside a small tank. The basic idea is to allow to the control algorithm to select an appropriate characteristic of the controller driving the air compressor, from an available set. In this first approach, the goal is to make functional the hardware circuits and to design the software support inside an Integrated Development Environment with a Very High Level Programming Language. After some functional tests, future work is intended to implement artificial intelligent based algorithms in order to exploit the multicharacteristics features with a fuzzy decisions set for selecting an optimal control. The main parts of the controller are an industrial pressure sensor, a PIC (TM) 16F877 microcontroller from Microchip (TM) and the air pressure part consisting, mainly, from a car compressor and a small tank. Additional elements make the operation safe. The solution with the microcontroller is put in operation in parallel with another one, using an industrial digital controller from Honeywell (TM). The platform is intended both for research activities, dealing with all kind of control algorithms implemented in software, associated with pneumatic systems, and for academic purpose, joining in an unique structure sensors, microelectronics, interface techniques, industrial controllers, motors, pneumatic elements and software.

BACKGROUNDFilling creams can provide an adequate substrate for spoilage yeasts because some yeasts can tolerate the high osmotic stress in these products. To discover the source of spoilage of a cream-filled baked product, end products, raw materials, indoor air and work surfaces were subjected to microbiological and molecular analyses. The efficacy of disinfectants against spoilage yeasts was also assessed. RESULTSThe analyses on end products revealed the presence of the closest relatives to Zygosaccharomyces bailii with counts ranging from 1.40 to 4.72logcfug(-1). No spoilage yeasts were found in the indoor air and work surfaces. Polymerase chain reaction-denaturing gradient gel electrophoresis analysis, carried out directly on filling creams collected from unopened cans, showed the presence of bands ascribed to the closest relatives to Z.bailii sensu lato, although with counts<1logcfug(-1). Susceptibility testing of yeast isolates to disinfectants showed a significantly lower effect of 10% alkyl dimethyl benzyl ammonium chloride. Different responses of isolates to the tested disinfectants were seen. CONCLUSIONTo guarantee the quality of end products, reliable and sensitive methods must be used. Moreover, hygiene and the application of good manufacturing practices represent the most efficient way for the prevention and minimization of cross-contamination.

The l(1)-optimal digital autopilot needed to control of the roll for an aircraft under an arbitrary unmeasured disturbances is addressed in this paper. This autopilot has to achieve a desired lateral motion control via minimizing the upper bound on the absolute value of the difference between the given and true roll angles. It is ensured by means of the two digital l(1)-optimal controllers of PI type The main result consists in establishing the fact that this controller can be robust in the presence of parametric and nonparametric uncertainties.

Autoimmune regulator (Aire) is essential in the perinatal period to prevent the multiorgan autoimmunity. Here we show that Aire-regulated single positive thymocyte trafficking in neonatal period is critical for thymic egress. Reduced thymic emigration was found in Aire(-/-) mice during neonatal period, leading to enhanced homeostatic expansion of peripheral T cells as early as 2 weeks of age. In neonatal Aire(-/-) mice, thymic expression of CCR7 ligands were dramatically reduced, resulting in decreased thymocyte motility and thymocyte emigration. This reduction of thymic egress in Aire(-/-) mice was alleviated beyond 3 weeks of age by an early upregulation of S1P(1) signaling. As the numbers and quality of thymic emigrants are essential for the establishment and maintenance of peripheral tolerance, the reduced thymic emigration during neonatal period may deteriorate autoimmunity caused by the emigration of autoreactive T cells.

BACKGROUND: Characterizing associations between the upper and lower airways is important for asthma management. OBJECTIVES: This study aimed to assess the determinants of incomplete asthma control in patients with allergic rhinitis (AR) and asthma. METHODS: Multiple factors including age, sex, atopy, smoking history, medication use, Asthma Control Questionnaire (ACQ) score, FEV1, fraction of exhaled nitric oxide (F-ENO), and rhinitis questionnaire score were examined. AR was defined by rhinitis symptoms and the sensitization to inhaled allergens. ACQ was used to dichotomize the subjects into the incompletely controlled group (ACQ score >= 0.75) and the well-controlled group. The factors that contribute to incomplete asthma control were assessed by a multivariate analysis. RESULTS: A total of 260 patients with AR and asthma were enrolled and 108 patients (42%) were classified as incomplete asthma control. The incompletely controlled group was older (P<.05), and had more airflow limitation, more airway inflammation, and more severe rhinitis symptoms (all P<.001). In contrast, the well-controlled group was more likely to be taking nasal corticosteroids (NCSs) (P<.01). In a multivariate model adjusted by age, asthma treatment, airflow limitation, and FENO, persistence and severity of rhinitis (odds ratio [OR], 2.57; 95% CI, 1.41-4.70, and OR, 2.00; 95% CI, 1.10-3.65) and nonuse of NCSs (OR, 3.83; 95% CI, 1.50-9.81) were independently associated with incomplete asthma control. CONCLUSIONS: The persistence and severity of AR and the use of NCSs were associated with the level of asthma control in patients with AR and asthma. Further studies are required to determine whether appropriate treatment of rhinitis would improve asthma control. (C) 2016 American Academy of Allergy, Asthma & Immunology
