Parental‐genome dosage effects on the transcriptome of F1 hybrid triploid embryos of Arabidopsis thaliana

Genomic imprinting in the seed endosperm could be due to unequal parental-genome contribution effects in triploid endosperm tissue that trigger parent-of-origin specific activation and/or silencing of loci prone to genomic imprinting. To determine whether genomic imprinting is triggered by unequal parental-genome contribution effects, we generated a whole-genome transcriptome dataset of F1 hybrid triploid embryos (as mimics of F1 hybrid triploid endosperm). For the vast majority of genes, the parental contributions to their expression levels in the F1 triploid hybrid embryos follow a biallelic and linear expression pattern. While allele-specific expression (ASE) bias was detected, such effects were predominantly parent-of-origin independent. We demonstrate that genomic imprinting is largely absent from F1 triploid embryos, strongly suggesting that neither triploidy nor unequal parental-genome contribution are key triggers of genomic imprinting in plants. However, extensive parental-genome dosage effects on gene expression were observed between the reciprocal F1 hybrid embryos, particularly for genes involved in defence response and nutrient reservoir activity, potentially leading to the seed size differences between reciprocal triploids. We further determined that unequal parental-genome contribution in F1 triploids can lead to overexpression effects that are parent-of-origin dependent, and which are not observed in diploid or tetraploid embryos in which the parental-genome dosage is balanced. Overall, our study demonstrates that neither triploidy nor unequal parental-genome contribution is sufficient to trigger imprinting in plant tissues, suggesting that genomic imprinting is an intrinsic and unique feature of the triploid seed endosperm.
Differences in Pharmacy Interventions at a Psychiatric Hospital: Comparison of Staff Pharmacists, Pharmacy Faculty, and Student Pharmacists

Purpose Previous evidence suggests psychiatric pharmacists have improved patient symptoms and provide valuable information. However, there are limited recent data regarding clinical pharmacists performing interventions in a psychiatric setting and its effects on costs. Additionally, there are no data that differentiate between psychiatric hospital staff pharmacists' (HSP), faculty clinical pharmacists' (FCP), and student pharmacists' (SP) interventions. Therefore, the objective of this study is to evaluate and describe interventions made by HSPs, FCPs, and SPs in a psychiatric hospital and cost savings. Methods A retrospective review of interventions made in a psychiatric hospital over 18 months was performed. Descriptive statistics and cost analysis were also determined through Pharmacy OneSource. Results A total of 2,220 interventions were made. Among HSPs (n = 4), there were 1,734 interventions including clarifications of orders (n = 592) and MAR discrepancies (n = 385). FCPs (n = 2) contributed 358 interventions consisting of dose recommendations/adjustments (n = 78), drug lab/level recommendations (n = 47), and therapeutic recommendations (n = 37). Additionally, SPs (n = 27) made 128 interventions including patient medication history (n = 31), drug information (n = 30), and counseling patients (n = 25). Annual cost savings were estimated at $125,500 with approximately 90% contributed by HSPs. Conclusion Pharmacy personnel contributed a considerable amount of interventions providing a cost savings to the hospital. Also, HSPs provided a greater number of interventions resulting in decreased costs. In our setting, HSPs, FCPs, and SPs contribute different clinical therapeutic interventions that may optimize patient care.
Upstream kinases of plant SnRKs are involved in salt stress tolerance

Summary Sucrose non‐fermenting 1‐related protein kinases (SnRKs) are important for plant growth and stress responses. This family has three clades: SnRK1, SnRK2 and SnRK3. Although plant SnRKs are thought to be activated by upstream kinases, the overall mechanism remains obscure. Geminivirus Rep‐Interacting Kinase (GRIK)1 and GRIK2 phosphorylate SnRK1s, which are involved in sugar/energy sensing, and the grik1‐1 grik2‐1 double mutant shows growth retardation under regular growth conditions. In this study, we established another Arabidopsis mutant line harbouring a different allele of gene GRIK1 (grik1‐2 grik2‐1) that grows similarly to the wild‐type, enabling us to evaluate the function of GRIKs under stress conditions. In the grik1‐2 grik2‐1 double mutant, phosphorylation of SnRK1.1 was reduced, but not eliminated, suggesting that the grik1‐2 mutation is a weak allele. In addition to high sensitivity to glucose, the grik1‐2 grik2‐1 mutant was sensitive to high salt, indicating that GRIKs are also involved in salinity signalling pathways. Salt Overly Sensitive (SOS)2, a member of the SnRK3 subfamily, is a critical mediator of the response to salinity. GRIK1 phosphorylated SOS2 in vitro, resulting in elevated kinase activity of SOS2. The salt tolerance of sos2 was restored to normal levels by wild‐type SOS2, but not by a mutated form of SOS2 lacking the T168 residue phosphorylated by GRIK1. Activation of SOS2 by GRIK1 was also demonstrated in a reconstituted system in yeast. Our results indicate that GRIKs phosphorylate and activate SnRK1 and other members of the SnRK3 family, and that they play important roles in multiple signalling pathways in vivo.

Periapical Bone Healing After Apicoectomy With and Without Retrograde Root Filling With Mineral Trioxide Aggregate: A 6-year Follow-Up of a Randomized Controlled Trial. J Endod. 2016 Apr;42(4):533-537 INTRODUCTION: In cases of posttreatment periapical disease, retreatment may be necessary. To choose the most appropriate retreatment method, knowledge of the long-term prognosis is important. Surgical endodontic retreatment (SER) is a relevant treatment method. This study assessed changes in outcome from 1 to 6 years after surgery. METHODS: The SER was performed on teeth randomly allocated to have an MTA root-end filling (MTA group) or smoothing of the orthograde gutta-percha filling after apicoectomy (GP group). Patients participating in the 1-year follow-up were reinvited for a 6-year clinical and radiographic examination. Three observers assessed treatment outcome both clinically and radiographically from the 1-year and 6-year follow-up examination. RESULTS: At the 6-year follow-up, 39 of 52 teeth were available and examined (75% participation rate). In the MTA group, 16 of 19 teeth (86%) and in the GP group 11 of 20 teeth (55%) were assessed as successful (P 1⁄4 .04). In the MTA group and the GP group, 80% and 90%, respectively, of teeth assessed as successful at the 1-year follow-up remained successful. All unsuccessful teeth in the MTA group (3 teeth) were lost because of vertical root fracture. CONCLUSIONS: The proportion of healed cases was larger in the MTA group than in the GP group at both the 1-year and 6-year follow-up. Findings indicate that a 1-year follow-up may not be sufficient in assessing the long-term outcome of surgical endodontic retreatment. With a longer follow-up, other factors not directly related to the endodontic treatment may be relevant for a successful outcome. This needs further investigation in larger patient samples.
Exploring family relationships through associations of comfort, relatedness states, and life closure in hospice patients: A pilot study

Abstract Objective: Research at the end of life tends to focus on the dying patient's symptoms, often overlooking issues associated with family interactions. However, many families struggle just to maintain or initiate these valuable connections. The purpose of our pilot study was to explore family relationships at the end of life and investigate associations among perceived comfort, relatedness states, and life closure. Method: This descriptive study used a cross-sectional design, and a convenience sample (n = 30; 18 women; mean age = 71 years) was recruited from patients admitted to a large not-for-profit hospice in northeastern Ohio. In-person interviews using the Hospice Comfort Questionnaire, Relatedness States Visual Analog Scales, and the Life-Closure Scale provided data for analyses. Results: Family interactions that were not associated with the physical tasks of caregiving were related to life closure (r = 0.36, p = 0.001), and life closure and comfort were highly correlated (r = 0.69, p < 0.001). Participants residing in an inpatient setting had higher levels of involvement (t[18] = –2.07, p = 0.05) and comfort in relationships (t[28] = –2.06, p = 0.05) than those in the home setting. Significance of Results: This is the first known study investigating the associations among comfort, relatedness, and life closure at the end of life. The majority of participants had high levels of involvement and comfort in their relationships, and they preferred interactions that required minimal effort. Studies that focus on both patients' and family members' perceptions of relationships are needed as well as outcome studies that test simple interventions.
Research activity of specialist registrars

AIMS AND METHOD There has been much discussion about the productivity and training value of protected research sessions at specialist registrar (SpR) level. We used questionnaire survey to investigate the research experience of senior psychiatric SpRs and first-year psychiatric consultants in Scotland. RESULTS The survey had an 80% response rate. Two-thirds of respondents were able to take protected research sessions, and a similar proportion had published research work during their higher training. Specific difficulties in conducting research are identified and discussed. CLINICAL IMPLICATIONS Scottish SpRs in psychiatry are usually able to protect research sessions, but experience difficulties with lack of experience, resources and supervision. Almost a third of those near the end of their training have published nothing. It is important to explore options other than research projects to gain relevant research experience.
Why are children and adolescents referred for psychiatric assessment without fulfiling diagnostic criteria for any psychiatric disorder?

BACKGROUND Clinicians often experience that children are referred for psychiatric evaluation without fulfiling the diagnostic criteria of any psychiatric disorders. This study investigates factors that might lead children to psychiatric referral without any psychiatric disorder. METHOD Children/adolescents who were referred for psychiatric assessment (referred group) (n = 418, mean age = 10.82 years, SD = 3.81) and a control group (n = 48, mean age = 10.38 years, SD = 3.77) were evaluated by the Mini International Neuropsychiatric Interview Kid (MINI Kid) and the Erfassung der Lebensqualität Kindern und Jugendlichen (Measure of Quality of Life for Children and Adolescents). The referred group was further divided into two subgroups: referred subgroup without MINI Kid diagnosis (n = 61) and referred subgroup with MINI Kid diagnosis (n = 357). Subjects less than 18 years old were included and there was no lower age limit. RESULTS Attention-deficit/hyperactivity disorder (ADHD) symptoms significantly increased the odds for referral as social phobia symptoms significantly decreased the odds for psychiatric referral. Regarding quality of life (QoL), the control group showed significantly less impairment when compared with the referred group; the two referred subgroup with and without diagnosis did not differ significantly. CONCLUSIONS ADHD symptoms, even in a subthreshold level and impaired QoL represent risk factors for psychiatric referral in children. Secondary prevention of children should target to screen subthreshold ADHD symptoms and QoL.
The Pepper Mannose-Binding Lectin Gene CaMBL1 Is Required to Regulate Cell Death and Defense Responses to Microbial Pathogens1[C][W][OA]

Plant mannose-binding lectins (MBLs) are crucial for plant defense signaling during pathogen attack by recognizing specific carbohydrates on pathogen surfaces. In this study, we isolated and functionally characterized a novel pepper (Capsicum annuum) MBL gene, CaMBL1, from pepper leaves infected with Xanthomonas campestris pv vesicatoria (Xcv). The CaMBL1 gene contains a predicted Galanthus nivalis agglutinin-related lectin domain responsible for the recognition of high-mannose N-glycans but lacks a middle S-locus glycoprotein domain and a carboxyl-terminal PAN-Apple domain. The CaMBL1 protein exhibits binding specificity for mannose and is mainly localized to the plasma membrane. Immunoblotting using a CaMBL1-specific antibody revealed that CaMBL1 is strongly expressed and accumulates in pepper leaves during avirulent Xcv infection. The transient expression of CaMBL1 induces the accumulation of salicylic acid (SA), the activation of defense-related genes, and the cell death phenotype in pepper. The G. nivalis agglutinin-related lectin domain of CaMBL1 is responsible for cell death induction. CaMBL1-silenced pepper plants are more susceptible to virulent or avirulent Xcv infection compared with unsilenced control plants, a phenotype that is accompanied by lowered reactive oxygen species accumulation, reduced expression of downstream SA target genes, and a concomitant decrease in SA accumulation. In contrast, CaMBL1 overexpression in Arabidopsis (Arabidopsis thaliana) confers enhanced resistance to Pseudomonas syringae pv tomato and Alternaria brassicicola infection. Together, these data suggest that CaMBL1 plays a key role in the regulation of plant cell death and defense responses through the induction of downstream defense-related genes and SA accumulation after the recognition of microbial pathogens.
A systematic review of studies on psychosocial late effects of childhood cancer: Structures of society and methodological pitfalls may challenge the conclusions

High survival rates after childhood cancer raise attention to possible psychosocial late effects. We focus on predictors of psychosocial outcomes based on diagnosis, treatment, demography, somatic disease, and methodological problems. Overall, survivors evaluate their health‐related quality of life to be normal or even better than controls, although virtually all diagnostic subgroups report psychosocial impairment. Central nervous system tumor survivors have significant psychosocial problems. Negative outcomes were associated with cranial radiation therapy, female gender, and young age at diagnosis. Significant methodological problems hamper current knowledge. Systematic registration of psychosocial and somatic problems at diagnosis and prospectively through protocols is needed.

Validação do mini-questionário de qualidade de vida em hipertensão arterial (MINICHAL) para o português (Brasil)

BACKGRAOUND: The assessment of quality of life has been considered an essential parameter in understanding the impact of arterial hypertension. OBJECTIVE: To translate into portuguese, cross-culturally adapt and validate the questionnaire specific for the assessment of quality of life known as "Mini Cuestionario de Calidad de Vida en Hipertension Arterial" (MINICHAL). METHODS: Two independent translations of MINICHAL were made into brazilian portuguese. Later, these two translations were harmonized yielding a version that was back-translated into the source language. This version was revised by a committee of judges and the new version was tested in a pilot study. After the cross-cultural adaptation, the final version of the instrument was administered to a sample of 300 patients. The psychometric properties of the questionnaire such as reliability and construct validity were analyzed. The internal consistency of the instrument was measured by Cronbachs alpha coefficient. RESULTS: In the brazilian version of MINICHAL, Cronbachs alpha coefficients of internal consistency reliability were 0.88 for the Mental Status domain and 0.85 for the Somatic Manifestations domain. As to content validity, the judges assessment attained a high level of agreement (75.44%). The factor analysis confirmed both domains, with differences in one item which was included in factor 2. The control group presented significant differences relative to hypertensive patients (t=4.86, gl=276.8, p< 0.001). CONCLUSION: The brazilian version of MINICHAL was successfully validated and represents a useful and reliable instrument for assessing the quality of life of brazilian hypertensive patients.
Arabidopsis MPK3 and MPK6 Play Different Roles in Basal and Oligogalacturonide- or Flagellin-Induced Resistance against Botrytis cinerea1[W]

Mitogen-activated protein kinases (MAPKs) are fundamental components of the plant innate immune system. MPK3 and MPK6 are Arabidopsis (Arabidopsis thaliana) MAPKs activated by pathogens and elicitors such as oligogalacturonides (OGs), which function as damage-associated molecular patterns, and flg22, a well-known microbe-associated molecular pattern. However, the specific contribution of MPK3 and MPK6 to the regulation of elicitor-induced defense responses is not completely defined. In this work we have investigated the roles played by these MAPKs in elicitor-induced resistance against the fungal pathogen Botrytis cinerea. Analysis of single mapk mutants revealed that lack of MPK3 increases basal susceptibility to the fungus, as previously reported, but does not significantly affect elicitor-induced resistance. Instead, lack of MPK6 has no effect on basal resistance but suppresses OG- and flg22-induced resistance to B. cinerea. Overexpression of the AP2C1 phosphatase leads to impaired OG- and flg22-induced phosphorylation of both MPK3 and MPK6, and to phenotypes that recapitulate those of the single mapk mutants. These data indicate that OG- and flg22-induced defense responses effective against B. cinerea are mainly dependent on MAPKs, with a greater contribution of MPK6.
Myosin XI-Dependent Formation of Tubular Structures from Endoplasmic Reticulum Isolated from Tobacco Cultured BY-2 Cells1[W][OA]

The reticular network of the endoplasmic reticulum (ER) consists of tubular and lamellar elements and is arranged in the cortical region of plant cells. This network constantly shows shape change and remodeling motion. Tubular ER structures were formed when GTP was added to the ER vesicles isolated from tobacco (Nicotiana tabacum) cultured BY-2 cells expressing ER-localized green fluorescent protein. The hydrolysis of GTP during ER tubule formation was higher than that under conditions in which ER tubule formation was not induced. Furthermore, a shearing force, such as the flow of liquid, was needed for the elongation/extension of the ER tubule. The shearing force was assumed to correspond to the force generated by the actomyosin system in vivo. To confirm this hypothesis, the S12 fraction was prepared, which contained both cytosol and microsome fractions, including two classes of myosins, XI (175-kD myosin) and VIII (BY-2 myosin VIII-1), and ER-localized green fluorescent protein vesicles. The ER tubules and their mesh-like structures were arranged in the S12 fraction efficiently by the addition of ATP, GTP, and exogenous filamentous actin. The tubule formation was significantly inhibited by the depletion of 175-kD myosin from the S12 fraction but not BY-2 myosin VIII-1. Furthermore, a recombinant carboxyl-terminal tail region of 175-kD myosin also suppressed ER tubule formation. The tips of tubules moved along filamentous actin during tubule elongation. These results indicated that the motive force generated by the actomyosin system contributes to the formation of ER tubules, suggesting that myosin XI is responsible not only for the transport of ER in cytoplasm but also for the reticular organization of cortical ER.
Dynamic Alternations in Cellular and Molecular Components during Blossom-End Rot Development in Tomatoes Expressing sCAX1, a Constitutively Active Ca2+/H+ Antiporter from Arabidopsis1[W][OA]

Although calcium (Ca) concentration in cellular compartments has been suggested to be tightly regulated, Ca deficiency disorders such as blossom-end rot (BER) in tomato (Solanum lycopersicum) fruit may be induced by abnormal regulation of Ca partitioning and distribution in the cell. The objectives of this work were to analyze the effects of high expression of the constitutively functional Arabidopsis (Arabidopsis thaliana) Ca2+/H+ exchanger (sCAX1) tonoplast protein in tomato fruit on cellular Ca partitioning and distribution, membrane integrity, and the transcriptional profile of genes potentially involved in BER development. Wild-type and sCAX1-expressing tomato plants were grown in a greenhouse. Wild-type plants did not develop BER, whereas sCAX1-expressing plants reached 100% BER incidence at 15 d after pollination. The sCAX1-expressing fruit pericarp had higher total tissue and water-soluble Ca concentrations, lower apoplastic and cytosolic Ca concentrations, higher membrane leakage, and Ca accumulation in the vacuole of sCAX1-expressing cells. Microarray analysis of healthy sCAX1-expressing fruit tissue indicated down-regulation of genes potentially involved in BER development, such as genes involved in membrane structure and repair and cytoskeleton metabolism, as well as up-regulation of genes that may have limited BER damage expansion, such as genes coding for heat shock proteins, glutathione S-transferases, and peroxidases. The results indicate that the high expression of the sCAX1 gene reduces cytosolic and apoplastic Ca concentrations, affecting plasma membrane structure and leading to BER symptom development in the fruit tissue.
