Defined as sexually explicit material that elicits erotic thoughts, feelings, and behaviours, internet pornography is a prevalent form of media that may facilitate problematic use and craving for engagement. Research suggests that superordinate cognitions and information processing, such as desire thinking and metacognition, are central to the activation and escalation of craving in addictive behaviours. The current study aimed to contribute to the literature by testing the proposed metacognitive model of desire thinking and craving in a sample of problematic pornography users, while revising the model by incorporating negative affect...

PURPOSE: Bladder cancer (BC) is a common disease with disparate treatment options and variable outcomes. Despite the disease's high prevalence, little is known of the lived experience of affected patients. National patient experience surveys suggest that those with BC have poorer experiences than those with other common cancers. The aim of this review is to identify first-hand accounts of the lived experiences of diagnosis through to survivorship. METHOD: This is a systematic review of the qualitative evidence reporting first-hand accounts of the experiences of being diagnosed with, treated for and surviving bladder cancer...

Over the past few decades, the hazards associated with the extensive use of organictin compounds have become an issue of extreme concern, while at present the effects of these substances on amphibians remain poorly understood. In the present study, we chose azocyclotin, one of common use acaricides in China. We focused on sexual development and steroidogenesis disrupting effects of azocyclotin in the Xenopus laevis. Tadpoles were exposed to azocyclotin (0.05 and 0.5μg/L) for long-term (4 months) study. Results showed that exposure to azocyclotin caused developmental toxicity, including decreased survival, body weight, body length, gonadosomatic index, hepatosomatic index and female phenotype...

An estimated 800 000 suicide deaths occur worldwide. The global suicide rate is 11.4 per 100 000 population; 15.0/100 000 for males and 8.0/100 000 for females. Globally, suicide is the second leading cause of death in 15-29 year olds. In a collaborative effort to reduce the high rates of suicide and mental health problems among youth across Europe, the European Union 7th Framework funded the Saving and Empowering Young Lives in Europe (SEYLE) project. SEYLE is a randomized controlled trial (RCT) aimed to promote mental health and healthy lifestyles, while preventing psychopathology and suicidal behaviours among adolescents...

OBJECTIVE: The aim was to analyse those syndromes without fever in travellers who return from tropical regions evaluated at our Department of Infectology and Tropical Medicine. Clarifying these conditions intends to reach earlier diagnoses and, perhaps, to avoid the emergence and spread of imported diseases, as well as to establish appropriate preventive measures. METHODS: An observational descriptive transversal study was performed, selecting those patients who returned from tropical regions without fever (n = 281), amongst all travellers evaluated in our department between 1998 and 2013...

BACKGROUND: Risk-reducing mastectomy (RRM) in patients at high risk has become more available and the rates of both bilateral (BRRM) and contralateral (CRRM) procedures are increasing. For women opting for RRM, psychosocial well-being, body image and sexuality are known to be important patient-reported outcomes. The aim of the present study was to investigate baseline health-related quality of life (HRQoL) and emotional distress (anxiety and depression) as predictors of body image and sexuality two years after RRM in women undergoing CRRM and BRRM...

Many aquatic animals grow into colonies of repeated, genetically identical, modules (zooids). Zooid interconnections enable colonies to behave as integrated functional units, while plastic responses to environmental changes may affect individual zooids. Plasticity includes the variable partitioning of resources to sexual reproduction, colony growth and maintenance. Maintenance often involves regeneration, which is also a routine part of the life history in some organisms, such as bryozoans. Here we investigate changes in regenerative capacity in the encrusting bryozoan Cryptosula pallasiana when cultured at different seawater pCO2 levels...

Unlike sexual reproduction, apomixis encompasses a number of reproductive strategies, which permit maternal genome inheritance without genetic recombination and syngamy. The key biological features of apomixis are the circumvention of meiosis (i.e., apomeiosis), the differentiation of unreduced embryo sacs and egg cells, and their autonomous development in functional embryos through parthenogenesis, and the formation of viable endosperm either via fertilization-independent means or following fertilization with a sperm cell...

This study builds on and extends previous research on nativity variations in adolescent health and risk behavior by addressing three questions: (1) whether and how generational status and age at migration are associated with timing of sexual onset among U.S. adolescents; (2) whether and how family instability mediates associations between nativity and sexual debut; and (3) whether and how these associations vary by gender. We find that first- and second-generation immigrant youth initiate sexual activity later than native youth...

The scientific understanding of fear and anxiety-in both normal and pathological forms-is presently limited by a predominance of studies that use male animals and Pavlovian fear conditioning-centered paradigms that restrict and assess specific behaviors (e.g., freezing) over brief sampling periods and overlook the broader contributions of the spatiotemporal context to an animal's behavioral responses to threats. Here, we use a risky "closed economy" system, in which the need to acquire food and water and the need to avoid threats are simultaneously integrated into the lives of rats, to examine sex differences in mitigating threat risk while foraging...

In the sexually reproductive organisms, gametes are produced by meiosis following a limited mitotic amplification. However, the intrinsic program switching cells from mitotic to meiotic cycle is unclear. Alternative polyadenylation (APA) is a highly conserved means of gene regulation and is achieved by the RNA 3'-processing machinery to generate diverse 3'UTR profiles. In Drosophila spermatogenesis, we observed distinct profiles of transcriptome-wide 3'UTR between mitotic and meiotic cells. In mutant germ cells stuck in mitosis, 3'UTRs of hundreds of genes were consistently shifted...
