Dysregulation of oxygen hemodynamic responses to synaptic train stimulation in a rat hippocampal model of subarachnoid hemorrhage

We investigated microvascular reactivity to synaptic train stimulation after induction of subarachnoid hemorrhage in adult rats, analyzing tissue oxygen levels [pO2] in intact hippocampus. In control rats, hippocampal pO2 averaged 11.4 mm Hg whereas hemodynamic responses averaged 13.1 mm Hg (to a 25 s train). After subarachnoid hemorrhage (at 2 days), we recorded a dramatic elevation in baseline pO2 in the hippocampus (to 68.4 mm Hg) accompanied by inverted pO2 responses to synaptic train stimulation (−9.46 mm Hg). These significant changes in baseline hippocampal pO2 and inverted pO2 responses after subarachnoid hemorrhage indicate severe alterations of neurovascular coupling and neuronal viability.
Mothers’ and fathers’ involvement in intervention programs for deaf and hard of hearing children

Abstract Purpose: Parental involvement in the rehabilitation process of deaf and hard of hearing (DHH) children is considered vital to children's progress. Today, fathers are more likely to be involved in their children’s care. Nevertheless, father involvement has been understudied and relatively little is known about their involvement in families with children who are deaf or hard of hearing. In addition, there are scant data on the correlates of parents’ involvement. This study explored similarities and differences in parental involvement between mothers and fathers in intervention programs for their D/HH children and tested a set of personal and social contextual variables that posited to affect parental involvement in a unique socio-cultural group. Methods: Thirty Israeli-Arab couples (mothers and fathers) of young D/HH children took part. Each parent completed four self-report measures of parental involvement, parenting stress, parental self-efficacy, and social support. Results: Mothers were significantly more involved than fathers in their child's intervention. Specifically, they report on higher interest and attendance and overall being more actively engaged with professionals in the child’s intervention. Both mothers and fathers had a rather passive style of involvement in their child's intervention. Parental self-efficacy and informal and formal social support were associated with father involvement. For mothers, only formal social support was associated with involvement. Conclusion: For the Israeli-Arab population, the findings underscore the differences between mothers’ and fathers’ multiple dimensions of involvement in the intervention program of their D/HH children and their predictors. The results suggest important avenues for prevention and intervention activities when working with families of children who are D/HH. Implications for rehabilitation Parental involvement in intervention programs for children who are deaf or hard of hearing (D/HH) is vital to children's progress and an essential component of implementing family-centered service provision. Understanding of both mothers and fathers multiple dimensions of involvement and the factors that facilitate or hinder their parental involvement in their children’s intervention programs, will equip professionals to better support parents of D/HH children aligned with the principles of family centered care service delivery. Mothers and fathers style of involvement reflects on gaps between the goals of family centered care and their implementation in the realities of everyday practice. The experiences and behaviors of mothers and fathers should not be seen as interchangeable.
The effect of plasma treatment and tightness factor on the low-stress mechanical properties of single jersey knitted wool fabrics

The effects of atmospheric pressure plasma treatment and the tightness factor on the low-stress mechanical properties of weft-knitted wool fabrics were evaluated using the Kawabata Evaluation System for Fabric (KES-F). The statistical analysis showed that the plasma treatment and the tightness factor had significant effects on the fabric low-stress mechanical properties (p-value < 0.05). Plasma-treated fabrics showed significantly higher bending and shear rigidity and hysteresis, compression energy, thickness, compressibility, surface friction and lower compression resilience and geometrical roughness values compared with untreated fabrics. An increase in the fabric tightness factor significantly increased fabric thickness, bending and shear rigidity and hysteresis, and decreased tensile extensibility and geometrical roughness. The relationship between primary handle attributes evaluated by Wool HandleMeter and KES-F mechanical properties was also investigated. The results confirmed a highly linear correlation between these two sets of data, where rough/smooth and hard/soft attributes evaluated by the Wool HandleMeter had the highest correlation with bending rigidity, shear properties and bending hysteresis, as measured by the KES-F.
The effect of the motion of the Sun on the light-time in interplanetary relativity experiments

In 2002, a measurement of the effect of solar gravity upon the phase of coherent microwave beams passing near the Sun was carried out by the Cassini mission, allowing a very accurate measurement of the PPN parameter γ. The data have been analysed with NASA's Orbit Determination Program (ODP) in the Barycentric Celestial Reference System, in which the Sun moves around the centre of mass of the solar system with a velocity v⊙ of about 15 m s−1; the question arises: what correction does this imply for the predicted phase shift? After a review of the way the ODP works, we set the problem in the framework of Lorentz (and Galilean) transformations and evaluate the correction; it is several orders of the magnitude below our experimental accuracy. We also discuss a recent paper (Kopeikin et al 2007 Phys. Lett. A 367 276), which claims wrong and much larger corrections, and clarify the reasons for the discrepancy.
Distance to invasive heart centre, performance of acute coronary angiography, and angioplasty and associated outcome in out-of-hospital cardiac arrest: a nationwide study

Aims To evaluate whether the distance from the site of event to an invasive heart centre, acute coronary angiography (CAG)/percutaneous coronary intervention (PCI) and hospital-level of care (invasive heart centre vs. local hospital) is associated with survival in out-of-hospital cardiac arrest (OHCA) patients. Methods and results Nationwide historical follow-up study of 41 186 unselected OHCA patients, in whom resuscitation was attempted between 2001 and 2013, identified through the Danish Cardiac Arrest Registry. We observed an increase in the proportion of patients receiving bystander CPR (18% in 2001, 60% in 2013, P < 0.001), achieving return of spontaneous circulation (ROSC) (10% in 2001, 29% in 2013, P < 0.001) and being admitted directly to an invasive centre (26% in 2001, 45% in 2013, P < 0.001). Simultaneously, 30-day survival rose from 5% in 2001 to 12% in 2013, P < 0.001. Among patients achieving ROSC, a larger proportion underwent acute CAG/PCI (5% in 2001, 27% in 2013, P < 0.001). The proportion of patients undergoing acute CAG/PCI annually in each region was defined as the CAG/PCI index. The following variables were associated with lower mortality in multivariable analyses: direct admission to invasive heart centre (HR 0.91, 95% CI: 0.89–0.93), CAG/PCI index (HR 0.33, 95% CI: 0.25–0.45), population density above 2000 per square kilometre (HR 0.94, 95% CI: 0.89–0.98), bystander CPR (HR 0.97, 95% CI: 0.95–0.99) and witnessed OHCA (HR 0.87, 95% CI: 0.85–0.89), whereas distance to the nearest invasive centre was not associated with survival. Conclusion Admission to an invasive heart centre and regional performance of acute CAG/PCI were associated with improved survival in OHCA patients, whereas distance to the invasive centre was not. These results support a centralized strategy for immediate post-resuscitation care in OHCA patients.
Particle number size distributions in urban air before and after volatilisation

Abstract. Aerosol particle number size distributions (size range 0.003–10 μm) in the urban atmosphere of Augsburg (Germany) were examined with respect to the governing anthropogenic sources and meteorological factors. The two-year average particle number concentration between November 2004 and November 2006 was 12 200 cm−3, i.e. similar to previous observations in other European cities. A seasonal analysis yielded twice the total particle number concentrations in winter as compared to summer as consequence of more frequent inversion situations and enhanced particulate emissions. The diurnal variations of particle number were shaped by a remarkable maximum in the morning during the peak traffic hours. After a mid-day decrease along with the onset of vertical mixing, an evening concentration maximum could frequently be observed, suggesting a re-stratification of the urban atmosphere. Overall, the mixed layer height turned out to be the most influential meteorological parameter on the particle size distribution. Its influence was even greater than that of the geographical origin of the prevailing synoptic-scale air mass. Size distributions below 0.8 μm were also measured downstream of a thermodenuder (temperature: 300 °C), allowing to retrieve the volume concentration of non-volatile compounds. The balance of particle number upstream and downstream of the thermodenuder suggests that practically all particles >12 nm contain a non-volatile core while additional nucleation of particles smaller than 6 nm could be observed after the thermodenuder as an interfering artifact of the method. The good correlation between the non-volatile volume concentration and an independent measurement of the aerosol absorption coefficient (R2=0.9) suggests a close correspondence of the refractory and light-absorbing particle fractions. Using the "summation method", an average diameter ratio of particles before and after volatilisation could be determined as a function of particle size. The results indicated that particles >60 nm contain a significantly higher fraction of non-volatile compounds, most likely black carbon, than particles
Differences in Adolescent Emotion Regulation and Impulsivity: A Group Comparison Study of School-Based Recovery Students

ABSTRACT Background: Recovery high schools (RHS) vary in organization and operating philosophy, but are designed to support the unique needs of students struggling with substance use disorders (SUD). Previous research on youth risk taking behaviors suggests emotion regulation is a key predictor of outcomes. Specifically, the ability to respond in adaptive rather than maladaptive ways is often associated with challenges of impulsivity, poor distress tolerance, and adolescent substance use. Objectives: The current study considers data from RHS students in order to answer research questions concerning impulsivity and emotion regulation of youth working to change their risk trajectories in comparison to group of typically developing youth. Methods: Participants (n = 114) in the study were composed of students enrolled in 3 RHS programs and a comparison group of similar aged youth (15–20 years) without an identified SUD. Data collection occurred through an anonymous online survey set of four measures of reactivity and impulsivity, emotion regulation, and parent and peer influence, as well as an online version of the Stroop Inhibitory Control Task. Results: Participants in the three RHS groups reported decreased emotion regulation abilities, increased impulsivity and increased peer influence when compared to the comparison group; differential effects within RHS are presented. Conclusions/Importance: Results are consistent with the extant literature that difficulty regulating emotions is associated with an increased risk for substance abuse and suggests these difficulties persist in early recovery. Results also suggest the need to better understand how different operating philosophies of programs influence student outcomes and the recovery process.
Toxicological role of an acyl glucuronide metabolite in diclofenac‐induced acute liver injury in mice

The acyl glucuronide (AG) metabolites of carboxylic acid‐containing drugs are potentially chemically reactive and are suggested to be implicated in toxicity, including hepatotoxicity, nephrotoxicity and drug hypersensitivity reactions. However, it remains unknown whether AG formation is related to toxicity in vivo. In this study, we sought to determine whether AG is involved in the pathogenesis of liver injury using a mouse model of diclofenac (DIC)‐induced liver injury. Mice that were administered DIC alone exhibited significantly increased plasma alanine aminotransferase levels, whereas mice that were pretreated with the UDP‐glucuronosyltransferase inhibitor (−)‐borneol (BOR) exhibited suppressed alanine aminotransferase levels at 3 and 6 h after DIC administration although not significant at 12 h. The plasma DIC‐AG concentrations were significantly lower in BOR‐ and DIC‐treated mice than in mice treated with DIC alone. The mRNA expression levels of chemokine (C‐X‐C motif) ligand 1 (CXCL1), CXCL2 and the neutrophil marker CD11b were reduced in the livers of mice that had been pretreated with BOR compared to those that had been administered DIC alone, whereas mRNA expression of the macrophage marker F4/80 was not altered. An immunohistochemical analysis at 12 h samples revealed that the numbers of myeloperoxidase‐ and lymphocyte antigen 6 complex‐positive cells that infiltrated the liver were significantly reduced in BOR‐ and DIC‐treated mice compared to mice that were treated with DIC alone. These results indicate that DIC‐AG is partly involved in the pathogenesis of DIC‐induced acute liver injury in mice by activating innate immunity and neutrophils.

A Comparative Study about Risk Factors Influencing Suicide Ideation between Korean and Multicultural Adolescents

Purpose: In South Korea, suicide mortality has rapidly increased, so it has become a major public health concern. Multicultural adolescents are regarded as a high-risk group due to their situation. In this study, we compared the prevalence and risk factors of suicide ideation between Korean and multicultural adolescents. Methods: Data from the eleventh Korean Youth Risk Behavior Web-based Survey (2015), collected by the Korean Centers for Disease Control and Prevention, were statistically analyzed using the descriptive statistics and multivariate logistic regression. The total participants were 63,376 in numbers. They were composed of 62,649 (98.9%) Korean and 727 (1.1%) multicultural adolescents. Results: I found that the prevalence of suicide ideation was significantly higher among the multicultural adolescents (15.8%) compared with those of Korean (11.3%). The risk factors of suicide ideation in the Korean group were co-residence without family, poor perceived health status, depressive mood, high stress level, poor perceived happiness level, and experience of violence. Conversely, the risk factors of the multicultural group were smoking, depressive mood, and experience of violence. Conclusion: These findings suggest that appropriate and practical prevention strategies should focus on psychological and environmental factors in order to prevent suicide ideation and reduce suicide behavior in Korean and multicultural adolescents.
The Relative Contribution of Symptomatic and Asymptomatic Plasmodium vivax and Plasmodium falciparum Infections to the Infectious Reservoir in a Low-Endemic Setting in Ethiopia

Background The majority of Plasmodium vivax and Plasmodium falciparum infections in low-endemic settings are asymptomatic. The relative contribution to the infectious reservoir of these infections compared to clinical malaria cases is currently unknown. Methods We assessed infectivity of passively recruited symptomatic malaria patients (n = 41) and community-recruited asymptomatic individuals with microscopy-detected (n = 41) and polymerase chain reaction (PCR)-detected infections (n = 82) using membrane feeding assays with Anopheles arabiensis mosquitoes in Adama, Ethiopia. Malaria incidence and prevalence data were used to estimate the contributions of these populations to the infectious reservoir. Results Overall, 34.9% (29/83) of P. vivax- and 15.1% (8/53) P. falciparum-infected individuals infected ≥1 mosquitoes. Mosquito infection rates were strongly correlated with asexual parasite density for P. vivax (ρ = 0.63; P < .001) but not for P. falciparum (ρ = 0.06; P = .770). Plasmodium vivax symptomatic infections were more infectious to mosquitoes (infecting 46.5% of mosquitoes, 307/660) compared to asymptomatic microscopy-detected (infecting 12.0% of mosquitoes, 80/667; P = .005) and PCR-detected infections (infecting 0.8% of mosquitoes, 6/744; P < .001). Adjusting for population prevalence, symptomatic, asymptomatic microscopy-detected, and PCR-detected infections were responsible for 8.0%, 76.2%, and 15.8% of the infectious reservoir for P. vivax, respectively. For P. falciparum, mosquito infections were sparser and also predominantly from asymptomatic infections. Conclusions In this low-endemic setting aiming for malaria elimination, asymptomatic infections were highly prevalent and responsible for the majority of onward mosquito infections. The early identification and treatment of asymptomatic infections might accelerate elimination efforts.
The thousand-andone cryptographers

Chaum’s Dining Cryptographers protocol crystallises the essentials of security just as other famous diners once captured deadlock and livelock: it is a benchmark for security models and their associated verification methods. Here we give a correctness proof of the Cryptographers in a new style, one in which stepwise refinement plays a prominent role. Furthermore, our proof applies to arbitrarily many Diners: to our knowledge we are only the second group to have done that. The proof is based on the Shadow Security Model which integrates noninterference and program refinement: with it, we try to make a case that stepwise development of security protocols is not only possible but actually is quite a good idea. It benefits from more than three decades’ of experience of how layers of abstraction can both simplify the design process and make its outcomes more likely to be correct.
Inequity in contraceptive care between refugees and other migrant women?: a retrospective study in Dutch general practice

Background Female refugees are at high risk of reproductive health problems including unmet contraceptive needs. In the Netherlands, the general practitioner (GP) is the main entrance to the healthcare system and plays a vital role in the prescription of contraceptives. Little is known about contraceptive care in female refugees in primary care. Objective To get insight into GP care related to contraception in refugees and other migrants compared with native Dutch women. Methods A retrospective descriptive study of patient records of refugees, other migrants and native Dutch women was carried out in five general practices in the Netherlands. The prevalence of discussions about contraception and prescriptions of contraceptives over the past 6 years was compared in women of reproductive age (15-49 years). Results In total, 104 refugees, 58 other migrants and 162 native Dutch women were included. GPs in our study (2 male, 3 female) discussed contraceptives significantly less often with refugees (51%) and other migrants (66%) than with native Dutch women (84%; P < 0.001 and P = 0.004, respectively). Contraceptives were less often prescribed to refugees (34%) and other migrants (55%) than to native Dutch women (79%; P < 0.001 and P = 0.001). Among refugees from Sub-Saharan Africa, contraception was significantly less often discussed (28.9%) compared with refugees from other regions (67.8%; P < 0.001). More refugees and other migrants had experienced unwanted pregnancies (14% respectively 9%) and induced abortions (12% respectively 7%) than native Dutch women (4% respectively 4%). Conclusion Contraceptives were significantly less often discussed with and prescribed to refugees and other migrant women compared with native Dutch women. More research is needed to elicit the reproductive health needs and preferences of migrant women regarding GP's care and experiences in discussing these issues. Such insights are vital in order to provide equitable reproductive healthcare to every woman regardless of her background.
Hypothalamic Glial-to-Neuronal Signaling during Puberty: Influence of Alcohol

Mammalian puberty requires complex interactions between glial and neuronal regulatory systems within the hypothalamus that results in the timely increase in the secretion of luteinizing hormone releasing hormone (LHRH). Assessing the molecules required for the development of coordinated communication networks between glia and LHRH neuron terminals in the basal hypothalamus, as well as identifying substances capable of affecting cell-cell communication are important. One such pathway involves growth factors of the epidermal growth factor (EGF) family that bind to specific erbB receptors. Activation of this receptor results in the release of prostaglandin-E2 (PGE2) from adjacent glial cells, which then acts on the nearby LHRH nerve terminals to elicit release of the peptide. Another pathway involves novel genes which synthesize adhesion/signaling proteins responsible for the structural integrity of bi-directional glial-neuronal communication. In this review, we will discuss the influence of these glial-neuronal communication pathways on the prepubertal LHRH secretory system, and furthermore, discuss the actions and interactions of alcohol on these two signaling processes.
Spreading of Pandemic Vibrio parahaemolyticus O3:K6 and Its Serovariants: A Re-analysis of Strains Isolated from Multiple Studies

In China, V. parahaemolyticus has been a leading cause of foodborne outbreaks and bacterial infectious diarrhea since the 1990s, and most infections have been associated with the pandemic V. parahaemolyticus O3:K6 and its serovariants. However, a comprehensive overview of the sero-prevalence and genetic diversity of the pandemic V. parahaemolyticus clone in China is lacking. To compensate for this deficiency, pandemic isolates in both clinical and environmental Chinese samples collected from multiple studies were analyzed in this study. Surprisingly, as many as 27 clinical pandemic serovariants were identified and were widely distributed across nine coastal provinces and two inland provinces (Beijing and Sichuan). O3:K6, O4:K68, and O1:KUT represented the predominant clinical serovars. Only four environmental pandemic serovariants had previously been reported, and they were spread throughout Shanghai (O1:KUT, O3:K6), Jiangsu (O3:K6, O4:K48), Zhejiang (O3:K6), and Guangdong (O4:K9). Notably, 24 pandemic serovariants were detected within a short time frame (from 2006 to 2012). The pandemic isolates were divided into 15 sequence types (STs), 10 of which fell within clonal complex (CC) 3. Only three STs (ST3, ST192, and ST305) were identified in environmental isolates. Substantial serotypic diversity was mainly observed among isolates within pandemic ST3, which comprised 21 combinations of O/K antigens. The pandemic O3:K6 serotype showed a high level of sequence diversity, which was shared by eight different STs (ST3, ST227, ST431, ST435, ST487, ST489, ST526, and ST672). Antimicrobial susceptibility testing revealed that most isolates shared similar antibiotic susceptibility profiles. They were resistant to ampicillin but sensitive to most other drugs that were tested. In conclusion, the high levels of serotypic and genetic diversity of the pandemic clone suggest that the involved regions are becoming important reservoirs for the emergence of novel pandemic strains. We underscore the need for routine monitoring to prevent pandemic V. parahaemolyticus infection, which includes monitoring antimicrobial responses to avoid excessive misuse of antibiotics. Further investigations are also needed to delineate the specific mechanisms underlying the possible seroconversion of pandemic isolates.
