BACKGROUND: Current Chinese studies continue to view male homosexuality through a disease focused lens which pays limited attention to socio-cultural aspects of sexual behavior and HIV transmission. This qualitative study aimed to investigate how socio-cultural factors influence gay men's sexual beliefs and behaviors in contemporary China, and their implications for HIV epidemic. METHODS AND FINDINGS: Qualitative methodology was used in this study. During 2015-2016, in-depth interviews were conducted with 61 self identified gay men in Jiangxi, Henan, Heilongjiang, Guangdong, Jiangsu provinces and Chongqing municipality of China...

Organisms living in polar waters must cope with an extremely stressful environment dominated by freezing temperatures, high oxygen concentrations and UV radiation. To shed light on the genetic mechanisms on which the polar marine ciliate, Euplotes nobilii, relies to effectively cope with the oxidative stress, attention was focused on methionine sulfoxide reductases which repair proteins with oxidized methionines. A family of four structurally distinct MsrB genes, encoding enzymes specific for the reduction of the methionine-sulfoxide R-forms, were identified from a draft of the E...

Pain sensitivity and risk of chronic pain can be influenced by past experience. Childhood stress/adversity has been associated with chronic pain, mood disorders, and altered disease vulnerability decades later. As the rate of preterm birth and survival at earlier gestational ages increases, and advances in peri-operative care and surgery allow more complex surgical interventions to be performed in neonates, evaluation of treatment 'success' must extend beyond acute morbidity and mortality to encompass effects on subsequent neurodevelopmental outcome, and also sensory, cognitive and behavioral responses to pain in later life...

ATP-binding cassette transporter A1 (ABCA1) mediates cholesterol efflux to lipid-free apolipoproteins and regulates the generation of high density lipoproteins. Previously, we have shown that lack of Abca1 significantly increases amyloid deposition and cognitive deficits in Alzheimer's disease model mice expressing human amyloid-β protein precursor (APP). The goal of this study was to determine if ABCA1 plays a role in memory deficits caused by amyloid-β (Aβ) oligomers and examine neurite architecture of pyramidal hippocampal neurons...

Established tumors build a stressful and hostile microenvironment that blocks the development of protective innate and adaptive immune responses. Different subsets of immunoregulatory myeloid populations, including dendritic cells, myeloid-derived suppressor cells (MDSCs) and macrophages, accumulate in the stressed tumor milieu and represent a major impediment to the success of various forms of cancer immunotherapy. Specific conditions and factors within tumor masses, including hypoxia, nutrient starvation, low pH, and increased levels of free radicals, provoke a state of "endoplasmic reticulum (ER) stress" in both malignant cells and infiltrating myeloid cells...

BACKGROUND: Parents of children with autism spectrum disorder (ASD) frequently report poor psychological well-being. Positive reappraisal coping (PRC) is a coping strategy which offers a protective effect from anxiety and depression. However, the association between PRC and the psychological distress in parents of children with ASD has yet to be established. AIM: This study examines the association between PRC and the psychological distress in parents of children with ASD...

To maintain homeostatic equilibrium, living organisms have evolved complex adaptation systems that control an array of behavioural, autonomic, neuroendocrine and immune responses. One of the important switches The master switch of this system is the hypothalamic hormone corticotropin-releasing hormone (CRH), which together with a family of related peptides (urocortins, UCNs) orchestrate stress-coping responses that reinstate homeostasis. Persistent disturbances in the homeostatic equilibrium either due to inadequate or persistently uncontrolled responses have been associated with pathogenic mechanisms of disease...

Microcystin-LR (MCLR) and copper are commonly found in eutrophic water bodies because of eutrophic run-offs, cyanobacterial blooms, and copper algicide applications. However, the ecotoxicological risk of their combination remains unknown. This study investigated the effect of MCLR, Cu, and their mixture on the growth and physiological responses of Vallisneria natans. Results showed that the combined toxicity of them was concentration dependent. Synergistic effects were elicited at low concentrations of MCLR and Cu exposure (≤0...

Ervin Gul, A Nuray Karanci
This study aimed to examine the roles of personality traits, traumatic event types, coping, rumination, and social support in explaining posttraumatic stress symptoms (PTS) and posttraumatic growth (PTG) in a representative community sample of 498 Turkish adults. The results of 2 multiple regression analyses showed that PTS was associated with neuroticism, experiencing events involving intentional/assaultive violence, intrusive and deliberate rumination, and fatalistic coping. In contrast, PTG was related to conscientiousness, openness to experience, injury/shocking and sudden-death type of events, deliberate rumination, problem-solving coping, and perceived social support...

BACKGROUND: The social environment the mother experiences during pregnancy and lactation can powerfully influence the offspring's behavioural profile. Our previous studies in wild cavies show that two different social environments during pregnancy and lactation bring about different behavioural strategies of male offspring later in life: An unstable social environment leads to a behavioural camouflage strategy, hypothesised to be beneficial at times of socially challenging situations...

Daily activities within an ant colony need precise temporal organization, and an endogenous clock appears to be essential for such timing processes. A clock drives locomotor rhythms in isolated workers in a number of ant species, but its involvement in activities displayed in the social context is unknown. We compared locomotor rhythms in isolated individuals and behavioral rhythms in the social context of workers of the ant Camponotus rufipes. Both forager and nurse workers exhibited circadian rhythms in locomotor activity under constant conditions, indicating the involvement of an endogenous clock...

BACKGROUND: Chagas disease (CD) profoundly affects the social and emotional dimensions of patients' lives, and disproportionately impacts poor, marginalized populations in Latin America. Biomedical treatment for CD fails to reach up to 99% of the people affected, and in any case seldom addresses the emotional health or socioeconomic conditions of patients. This study examines patient strategies for coping with CD in the department of Santa Cruz, Bolivia. METHODOLOGY: In this ethnographic study, semistructured interviews took place from March-June 2013 with 63 patients who had previously tested positive for CD...

Posttraumatic stress disorder (PTSD) represents one of the most common mental health disorders, particularly among veterans, and is associated with significant distress and impairment. This highly debilitating disorder is further complicated by common comorbid psychiatric disorders, such as substance use disorders (SUD). Individuals with PTSD and co-occurring SUD also commonly present with secondary symptoms, such as elevated depression. Little is known, however, about how these secondary symptoms are related to treatment outcome...

BACKGROUND: In cancer care settings, family caregivers often experience negative or little communication with the health professionals, and this negative communication and limited health-related information causes psychological distress in family caregivers to cancer patients. AIM: The first aim of this research is to investigate the relationship between communication with health professionals and psychological distress in family caregivers. The second aim is to investigate the mediating effects of self-efficacy in this hypothetical model...

BACKGROUND: Global efforts have increased facility-based childbirth, but substantial barriers remain in some settings. In Nigeria, women report that poor provider attitudes influence their use of maternal health services. Evidence also suggests that women in Nigeria may experience mistreatment during childbirth; however, there is limited understanding of how and why mistreatment this occurs. This study uses qualitative methods to explore women and providers' experiences and perceptions of mistreatment during childbirth in two health facilities and catchment areas in Abuja, Nigeria...

BACKGROUND: First-episode psychosis most often has its onset during late adolescence. In caring for the young person, families endure high levels of stress and depression. Meanwhile, the social networks of families often erode. Our group has previously shown that family cognitive behaviour therapy (CBT) leads to significantly improved perceived stress compared with specialist first-episode treatment as usual; however, there are well-known barriers to the dissemination of effective family interventions...

OBJECTIVE: This study estimates the effect of a targeted early childhood intervention program on global and experienced measures of maternal well-being utilizing a randomized controlled trial design. The primary aim of the intervention is to improve children's school readiness skills by working directly with parents to improve their knowledge of child development and parenting behavior. One potential externality of the program is well-being benefits for parents given its direct focus on improving parental coping, self-efficacy, and problem solving skills, as well as generating an indirect effect on parental well-being by targeting child developmental problems...

Curiosity, the tendency to engage in novel and challenging opportunities, may be an important source of resilience for those at risk for suicide. We hypothesized that curiosity would have a buffering effect against risk conferred by multiple sources of distress, whereby curiosity would be associated with reduced suicidal ideation and increased coping efficacy. As part of a larger intervention trial designed to improve coping skills and reduce suicidal ideation, 117 military veterans with suicidal ideation completed measures of curiosity and distress (perceived stress, depression, anxiety, and sleep disturbances) at baseline, and completed measures of suicidal ideation and coping efficacy (to stop negative thoughts, to enlist support from friends and family) at baseline and 3-, 6-, and 12-week follow up...
