Differences in perceived popularity and social preference between bullying roles and class norms.

The aim of this study was to examine differences in perceived popularity and social preference of bullying roles and class norms. In total, 1,339 students (48% girls) participated: 674 primary school (M = 10.41 years, SD = 0.

Depressive symptoms, ruminative thinking, marijuana use motives, and marijuana outcomes: A multiple mediation model among college students in five countries.

Background: Previous studies have evidenced that rumination and drinking motives may mediate the association between depressive symptoms and alcohol outcomes. The present study cross-culturally examined whether a similar mediation model may extend to marijuana. Specifically, we tested distinct rumination facets (problem-focused thoughts, counterfactual thinking, repetitive thoughts, and anticipatory thoughts) and marijuana use motives (social, coping, expansion, conformity, enhancement) as double-mediators of the paths from depressive symptoms to marijuana outcomes (use and consequences).

Structural and biochemical characterization of iminodiacetate oxidase from Chelativorans sp. BNC1.

Ethylenediaminetetraacetate (EDTA) is the most abundant organic pollutant in surface water because of its extensive usage and the recalcitrance of stable metal-EDTA complexes. A few bacteria including Chelativorans sp. BNC1 can degrade EDTA with a monooxygenase to ethylenediaminediacetate (EDDA) and then use iminodiacetate oxidase (IdaA) to further degrade EDDA into ethylenediamine in a two-step oxidation.

Peripheral changes in immune cell populations and soluble mediators after anti-PD-1 therapy in non-small cell lung cancer and renal cell carcinoma patients.

Patients with non-small cell lung cancer (NSCLC) and renal cell carcinoma (RCC) have shown benefit from anti-PD-1 therapies. However, not all patients experience tumor shrinkage, durable responses or prolonged survival, demonstrating the need to find response markers. In blood samples from NSCLC and RCC patients obtained before and after anti-PD-1 treatment, we studied leukocytes by complete blood cell count, lymphocyte subsets using flow cytometry and plasma concentration of nine soluble mediators, in order to find predictive biomarkers of response and to study changes produced after anti-PD-1 therapy.

Methods: This Phase II single-arm trial was designed to recruit 17 patients with relapsed penile cancer. The primary endpoint was objective (complete + partial) response rate (ORR; Response Evaluation Criteria in Solid Tumours [RECIST] v1.

Bedside to bench: defining the immunopathogenesis of psoriatic arthritis.

Psoriatic arthritis (PsA) is an immune-mediated, systemic inflammatory disorder. PsA can present with heterogeneous clinical features. Advances in understanding the immunopathogenesis of PsA have helped to facilitate the development of agents targeting specific components of the dysregulated inflammatory and immune responses relevant to PsA.

Post-traumatic stress and marijuana outcomes: The mediating role of marijuana protective behavioral strategies.

The present study investigated the mediating role of protective behavioral strategies for marijuana (PBSM) on the relationship between posttraumatic stress disorder (PTSD) and marijuana outcomes (i.e. marijuana use frequency, marijuana use quantity, cannabis use disorder (CUD) symptoms, and marijuana-related problems).

Human intracerebroventricular (ICV) injection of autologous, non-engineered, adipose-derived stromal vascular fraction (ADSVF) for neurodegenerative disorders: results of a 3-year phase 1 study of 113 injections in 31 patients.

We have chosen to test the safety of human intracerebroventricular (ICV) brain injections of autologous non-genetically-modified adipose-derived stromal vascular fraction (ADSVF). In this IRB-approved trial, 24 patients received ICV ADSVF via an implanted reservoir between 5/22/14 and 5/22/17. Seven others were injected via their ventriculo-peritoneal shunts.

Moral Injury, Substance Use, and Posttraumatic Stress Disorder Symptoms Among Military Personnel: An Examination of Trait Mindfulness as a Moderator.

Mindfulness-based approaches have been suggested as possible methods to treat moral injury in military personnel. However, empirical research has yet to evaluate if mindfulness acts as a protective factor for the possible negative effects of moral injury, such as alcohol use, drug use, or posttraumatic stress disorder (PTSD) symptoms. In this study, we investigated if five facets of mindfulness (i.

Prevalence of Mental Health Problems and Willingness to Participate in a Mindfulness Treatment: An Examination among Veterans Injured in Combat.

Numerous studies have demonstrated that combat-exposed military veterans are at risk for numerous psychiatric disorders and rates of comorbid mental health and substance use disorders are high. Veterans wounded in combat are a particularly high-risk group of military veterans, however treatment services are often underutilized among this group and it is unclear whether an online treatment program that targets emotional and physical distress (including mental health symptoms and substance use disorders) would be appealing to Veterans wounded in combat. The goal of the current study was to conduct formative research on whether veterans wounded in combat would be interested in an online mindfulness-based treatment to help them cope with emotional and physical discomfort.

Negative marijuana-related consequences among college students in five countries: measurement invariance of the Brief Marijuana Consequences Questionnaire.

Background And Aims: The 21-item Brief Marijuana Consequences Questionnaire (B-MACQ) has been shown to be a valid measure to assess negative marijuana-related consequences among US college students. The present study aimed to: (a) examine measurement invariance of the B-MACQ among college student marijuana users in five countries, (b) evaluate latent mean differences on the B-MACQ as a function of sex and country if invariance is met and (c) compare criterion-related validity across different countries and sex.

Design: Instrumental study.

Short- and long-term outcomes of arterial reconstruction on recipient splenic artery in adult liver transplantation. Single-center prospective study 25 years after first description.

Several techniques have been proposed for liver transplantation with inadequate hepatic artery (HA) anastomosis. We aimed to analyze outcomes of arterial reconstruction with the splenic artery (SA). This was a prospective study of our experience with recipients who underwent arterial anastomosis on the SA compared with patients who underwent standard HA.

Cross-cultural examination of college marijuana culture in five countries: Measurement invariance of the Perceived Importance of Marijuana to the College Experience Scale.

Marijuana internalized norms, measured by the Perceived Importance of Marijuana to the College Experience Scale (PIMCES; 8 items), has been found to be distinct from marijuana descriptive/injunctive norms and to be a unique robust predictor of marijuana-related outcomes among college students, yet the role of these beliefs has not been studied outside the U.S. Using confirmatory factor analysis, the present work examined the level of measurement invariance (i.

Transcriptional activation by MafR, a global regulator of Enterococcus faecalis.

Proteins that act as global transcriptional regulators play key roles in bacterial adaptation to new niches. These proteins recognize multiple DNA sites across the bacterial genome by different mechanisms. Enterococcus faecalis is able to survive in various niches of the human host, either as a commensal or as a leading cause of serious infections.

Antifungal Activity of Eugenol Derivatives against .

is a worldwide spread fungus that causes the grey mold disease, which is considered the most important factor in postharvest losses in fresh fruit crops. Consequently, the control of gray mold is a matter of current and relevant interest for agricultural industries. In this work, a series of phenylpropanoids derived from eugenol were synthesized and characterized.

Insomnia symptoms, cannabis protective behavioral strategies, and hazardous cannabis use among U.S. college students.

Previous research has reported that sleep problems longitudinally predict both onset of cannabis use and cannabis-related problems. However, the mediators of this relationship remain unclear. The present study examined (a) the concurrent relationship between insomnia symptoms and hazardous cannabis use and (b) examined whether use of protective behavioral strategies (PBS) for cannabis mediated this relationship among college student cannabis users.

Terrestrial diet influences mercury bioaccumulation in zooplankton and macroinvertebrates in lakes with differing dissolved organic carbon concentrations.

Dietary uptake is a key step in conveying both toxic mercury (Hg; particularly as highly bioavailable methylmercury, MeHg) and essential dietary biochemicals, such as polyunsaturated fatty acids (PUFA), across trophic levels within aquatic food webs. Using stable isotopes and fatty acids we evaluated the role of food sources in size-fractioned plankton and littoral macroinvertebrates for the bioaccumulation of total Hg and MeHg in six oligotrophic and one mesotrophic Swedish lakes with differing concentrations of dissolved organic carbon (DOC). We found that the consumption of both algal and terrestrial diets (assessed by PUFA and long-chain saturated fatty acids, respectively) predicted >66% of the Hg concentration variability in meso- (100-500 μm) and macrozooplankton (>500 μm) in oligotrophic lakes.

Marijuana protective behavioral strategies and marijuana refusal self-efficacy: Independent and interactive effects on marijuana-related outcomes.

Separately, research has identified use of marijuana protective behavioral strategies and marijuana refusal self-efficacy to be protective factors associated with less marijuana use and associated harms. To date, these factors have not been examined together. Using a large sample of college students recruited from 10 U.

Cyanobacteria as regulators of methylmercury production in periphyton.

Biotic mercury (Hg) methylation appears to depend on factors such as microbial activity and the concentration and bioavailability of Hg to the Hg-methylating organisms. Recently, the presence of cyanobacteria has been linked with high methylmercury (MeHg) concentrations. The aim of this work was to test MeHg production in microcosms, in relation to the amount of periphytic cyanobacteria, dissolved organic matter (DOM) and phosphorus concentrations, as well as periphytic primary production rates.

The Relationship Between Social Anxiety and Alcohol and Marijuana Use Outcomes Among Concurrent Users: A Motivational Model of Substance Use.

Background: College students with more social anxiety symptoms are particularly vulnerable to problematic alcohol and marijuana use given their susceptibility for elevated anxiety symptoms in social settings combined with the normative nature of substance use. Existing research has established substance use as coping motivated for these students when examining alcohol and marijuana use problems separately. The next step is to determine whether students with more social anxiety who use both substances do so for similar or different reasons.

When Humans Met Superbugs: Strategies to Tackle Bacterial Resistances to Antibiotics.

Bacterial resistance to antibiotics poses enormous health and economic burdens to our society, and it is of the essence to explore old and new ways to deal with these problems. Here we review the current status of multi-resistance genes and how they spread among bacteria. We discuss strategies to deal with resistant bacteria, namely the search for new targets and the use of inhibitors of protein-protein interactions, fragment-based methods, or modified antisense RNAs.
