Despite the exacerbating HIV transmission among migrant men who have sex with men (MSM) in China, few epidemiological studies explore their HIV testing/risk profiles. We sought to explore sociodemographic/behavioral correlates of HIV/syphilis and HIV testing among migrant MSM. A study was conducted among 3,588 HIV-uninfected MSM. Participants were recruited via short message services, peer referral, web-advertisement and community outreach. HIV/syphilis infections were lab-confirmed. Migrant MSM were more likely to be HIV-infected compared to local MSM...

BACKGROUND: Garzê and Aba form the second largest Tibetan-inhabited area of China. Blood services have never been reported for this region before. OBJECTIVE: To assess the current situation and analyse whether a safe and adequate blood supply has been developed in both Garzê and Aba. METHODS: We conducted a longitudinal survey covering the period 2011-2016. The subjects of interest were recruited from non-remunerated voluntary donation, blood testing, clinical transfusion practices and infrastructure of local blood service systems...

Between February 2015 and 2016, samples of the Indo-Pacific goldspotted spinefoot Siganus punctatus were taken from local fish markets, feeding sites and nursery grounds on the main island of Pohnpei, Micronesia, to ascertain sexual pattern, reproductive seasonality, age, growth and mortality. Microscopic examinations of gonads identified two seasonal peaks in reproduction: February to May and September to December, with evidence of some spawning activity in most months. Ripe females were observed 4 days on either side of the new moon...

BACKGROUND: Many pathogens secrete effector molecules to subvert host immune responses, to acquire nutrients, and/or to prepare host cells for invasion. One of the ways that effector molecules are secreted is through extracellular vesicles (EVs) such as exosomes. Recently, the malaria parasite P. falciparum has been shown to produce EVs that can mediate transfer of genetic material between parasites and induce sexual commitment. Characterizing the content of these vesicles may improve our understanding of P...

CONTEXT: The Creighton Model FertilityCare(TM) System (CrM) is a standardized approach for educating women about the biomarkers of their fertility. Couples can use this information for timing intercourse during "fertile" or "infertile" days in order to try to conceive or to avoid pregnancy. OBJECTIVES: The study of Creighton Model Effectiveness, Intentions, and Behaviors Assessment (CEIBA) was conducted to assess fertility motivations, intentions, fertility-related sexual behaviors, and their impact on effectiveness to avoid and to conceive among new users of the CrM...

Sea cucumbers are increasingly exploited for human consumption and for their curative properties, and many wild populations are now depleted or in danger of extinction. While aquaculture is seen as an alternative to fisheries and as a mean to restore wild populations, more knowledge is needed on their reproductive strategies to render this practice efficient, notably for fissiparous holothurians, which are some of the mobile animals able of asexual reproduction by transverse fission. Little information is available on their population genetic diversity and structure...

Floral displays, influencing attractiveness to insects, increase the number of pollinator visits and the efficiency of each visit in terms of pollen exchange and thus affect the plant reproductive success. Here, we conducted an in situ manipulation experiment to investigate whether the floral modifications affect reproductive success in natural orchid populations of Serapias lingua and Serapias vomeracea. We estimated male and female reproductive success of three treatment groups, disassembly of floral tube, cutting of lip, and painting of the callus surface, in terms of pollinaria removed/deposited and fruit production...

Many animals adjust their reproductive behavior according to nutritional state and food availability. Drosophila females for instance decrease their sexual receptivity following starvation. Insulin signaling, which regulates many aspects of insect physiology and behavior, also affects reproduction in females. We show that insulin signaling is involved in the starvation-induced reduction in female receptivity. More specifically, females mutant for the insulin-like peptide 5 (dilp5) were less affected by starvation compared to the other dilp mutants and wild-type flies...

PURPOSE OF REVIEW: Bisexual individuals are at increased risk for negative health outcomes compared to heterosexual individuals and often compared to gay/lesbian individuals as well. The goal of this article is to summarize the current evidence-base on bisexual health disparities, to describe factors that influence them, and to review interventions designed to improve the health of bisexual individuals. RECENT FINDINGS: Based on our review of the literature, we conclude that there is strong evidence that bisexual individuals are at increased risk for mental health and substance use problems...

Elderly people often suffer adverse health because of inflammation associated with poor metabolism and cardiovascular dysfunction, but these conditions present differently in men and women. We performed experiments in aged male and female mice to understand this sexual dimorphism. We focused on sphingosine 1-phosphate (S1P) signaling, which has both protective and detrimental effects on vascular and metabolic function. We examined vascular function of mesenteric (resistance) arteries from aged male and female wild-type (WT) mice compared to littermate S1P receptor 3 (S1PR3) knockouts (KO)...

Carotenoids have important roles in bird behavior, including pigmentation for sexual signaling and improving color vision via retinal oil droplets. Yellow carotenoids are diet-derived, but red carotenoids (ketocarotenoids) are typically synthesized from yellow precursors via a carotenoid ketolase. Recent research on passerines has provided evidence that a cytochrome p450 enzyme, CYP2J19, is responsible for this reaction, though it is unclear if this function is phylogenetically restricted. Here I provide evidence that CYP2J19 is the carotenoid ketolase common to Aves using the genomes of 65 birds and the retinal transcriptomes of 15 avian taxa...

INTRODUCTION: Recognizing the importance of sexual and reproductive health to patients with spina bifida (SB), pediatric urologists have taken responsibility for initiating conversations regarding this topic with adolescent and young adult SB patients. However, the sexual and reproductive health of women with SB remains under-investigated. It is unknown how many women are having babies, what mode of delivery is used, and if this has changed over time with the increasing life expectancy of these patients...

STUDY OBJECTIVE: Evidence suggests that vaccine-type human papillomavirus (HPV) prevalence may decrease in unvaccinated women after HPV vaccine introduction, indicating herd protection. The aim of this study was to determine factors associated with vaccine-type HPV (i.e. absence of herd protection) after vaccine introduction. DESIGN: We conducted three cross-sectional studies from 2006-2014 (n=1180): wave 1 (2006-2007), wave 2 (2009-2010), and wave 3 (2013-2014)...

BACKGROUND: Previous research has reported that sexual harassment can lead to reduced mental health. Few studies have focused on sexual harassment conducted by clients or customers, which might occur in person-related occupations such as eldercare work, social work or customer service work. This study examined the cross-sectional association between sexual harassment by clients or customers and depressive symptoms. We also examined if this association was different compared to sexual harassment conducted by a colleague, supervisor or subordinate...

Chronic hepatitis C (CHC) is caused by hepatitis C virus (HCV) infection. HCV infection causes acute hepatitis, and the majority of those infected progress to chronic hepatitis, and some of them develop cirrhosis and hepatocellular carcinoma. Transmission of HCV is parenteral, and the major transmission routes include drug abuse, insecure injections or medical procedures, contaminated syringes or needles, sexual contact with an HCV-infected person, vertical infection of newborns by infected mothers, the transfusion of blood or blood products contaminated with viruses, and organ transplants...

INTRODUCTION: Adverse childhood experiences (ACEs) are associated with a range of health outcomes and risk behaviors. In 2011-2012, the National Survey of Children's Health (NSCH) included questions about adverse family experiences (AFEs). AFE survey questions are similar to ACE questions, except there are no questions about emotional/physical/sexual trauma, and questions are asked of parents rather than children. Although the relationship between ACEs and work/school absenteeism has been studied, the relationships between AFEs of school-aged children, school performance, and buffering behaviors have not been explored in depth...
