Polyvictimization is a common experience for youth in the United States, with 20% nationally experiencing five or more different forms of victimization in the last year. Utilizing a large, national convenience sample of sexual and gender minority adolescents (N = 1177, 14-19 years old), the current study aimed to (a) generate the first estimates of last year polyvictimization (including nine victimization subtypes) for transgender, genderqueer, and cisgender (i.e., assigned birth sex aligns with gender identity) sexual minority adolescents and (b) identify social ecological correlates of last year polyvictimization...

Mouse lemurs are basal primates that rely on chemo- and acoustic signalling for social interactions in their dispersed social systems. We examined the urinary protein content of two mouse lemurs species, within and outside the breeding season, to assess candidates used in species discrimination, reproductive or competitive communication. Urine from Microcebus murinus and Microcebus lehilahytsara contain a predominant 10 kDa protein, expressed in both species by some, but not all, males during the breeding season, but at very low levels by females...

New attention to sexual dimorphism in normal mammalian physiology and disease has uncovered a previously unappreciated breadth of mechanisms by which females and males differentially exhibit quantitative phenotypes. Thus, in addition to the established modifying effects of hormones, which prenatally and postpubertally pattern cells and tissues in a sexually dimorphic fashion, sex differences are caused by extragonadal and dosage effects of genes encoded on sex chromosomes. Sex differences in immune responses, especially during autoimmunity, have been studied predominantly within the context of sex hormone effects...

Vocalizations are a crucial part of courtship and mating in a wide variety of species. Mating behavior, including courtship calls, is modulated by sex steroid hormones. Male mice produce courtship ultrasonic vocalizations to attract females during heterosexual encounters. However, rare is the knowledge on whether vocal behavior of mice changes under sterilant treatment which will affect gonadal hormone levels. In the present study, we treat male mice with quinestrol, which interferes with the release of the gonadotropin-releasing hormone (GnRH) and has a significant anti-fertility effect in rodents...

Preclinical research in animal models is important for understanding the neural pathways and pathophysiology underlying changes in sexual function after SCI. In vivo animal models, primarily rodents, have provided valuable information on the central pathways regulating sexual arousal and orgasm; however, further research is required in females and preclinical modeling of SCI that can be better translated to men and women. Translation of the autonomic and somatic regulation of sexual responses from preclinical models through clinical research correlates well with respect to the peripheral-spinal systems involved...

The evolution of sexual dimorphism is predicted to occur through reductions in between-sex genetic correlations (rmf) for shared traits, but the physiological and genetic mechanisms that facilitate these reductions remain largely speculative. Here, we use a paternal half-sibling breeding design in captive brown anole lizards (Anolis sagrei) to show that the development of sexual size dimorphism is mirrored by the ontogenetic breakdown of rmf for body size and growth rate. Using transcriptome data from the liver (which integrates growth and metabolism), we show that sex-biased gene expression also increases dramatically between ontogenetic stages bracketing this breakdown of rmf...

Many studies of sexual selection assume that individuals have equal mating opportunities and that differences in mating success result from variation in sexual traits. However, the inability of sexual traits to explain variation in male mating success suggests that other factors moderate the strength of sexual selection. Extrapair paternity is common in vertebrates and can contribute to variation in mating success and thus serves as a model for understanding the operation of sexual selection. We developed a spatially explicit, multifactor model of all possible female-male pairings to test the hypothesis that ecological (food availability) and social (breeding density, breeding distance, and the social mate's nest stage) factors influence an individual's opportunity for extrapair paternity in a socially monogamous bird, the black-throated blue warbler, Setophaga caerulescens...

PURPOSE: Research suggests that LGBT populations experience barriers to healthcare. Organizations such as the Institute of Medicine recommend routine documentation of sexual orientation (SO) and gender identity (GI) in healthcare, to reduce LGBT disparities. We explore patient views regarding the importance of SO/GI collection, and patient and provider views on risks and benefits of routine SO/GI collection in various settings. METHODS: We surveyed LGBT/non-LGBT patients and providers on their views on SO/GI collection...

The rate at which a population grows and spreads can depend on individual behaviour and interactions with others. In many species with two sexes, males and females differ in key life history traits (e.g. growth, survival, dispersal), which can scale up to affect population rates of growth and spread. In sexually reproducing species, the mechanics of locating mates and reproducing successfully introduce further complications for predicting the invasion speed (spread rate), as both can change nonlinearly with density...

Although morphine remains the primary drug prescribed for alleviation of severe or persistent pain, both preclinical and clinical studies have shown that females require 2-3 times more morphine than males to produce comparable levels of analgesia. In addition to binding to the neuronal μ opioid receptor (MOR), morphine binds to the innate immune receptor toll-like receptor 4 (TLR4) localized primarily on microglia. Morphine action at TLR4 initiates a neuroinflammatory response that directly opposes the analgesic effects of morphine...

A gender difference in stroke is observed throughout epidemiologic studies, pathophysiology, treatment and outcomes. We investigated the neuroprotective role of hemeoxygenase (HO) enzyme, which catabolizes free heme to bilirubin, carbon monoxide and biliverdin in the female brain after permanent ischemia. We have previously reported in male mice that genetic deletion of HO1 exacerbates the brain damage after permanent ischemia, and the mechanism of neuroprotection is dependent on the HO1/Wnt pathway; however, the role of HO1/Wnt mediated neuroprotection in the female brain is yet to be investigated...

MicroRNAs (miRNAs) are negative modulators of gene expression that fine-tune numerous biological processes. miRNA loss-of-function rarely results in highly penetrant phenotypes, but rather, influences cellular responses to physiologic and pathophysiologic stresses. Here, we have reported that a single member of the evolutionarily conserved miR-7 family, miR-7a2, is essential for normal pituitary development and hypothalamic-pituitary-gonadal (HPG) function in adulthood. Genetic deletion of mir-7a2 causes infertility, with low levels of gonadotropic and sex steroid hormones, small testes or ovaries, impaired spermatogenesis, and lack of ovulation in male and female mice, respectively...

Quality of life (QOL) has been studied extensively among cancer populations in high income countries where cancer care resources are available to many. Little is known concerning the QOL of cancer groups residing in Africa where resources can be scarce. The integrative review of the literature explored and critically examined studies that had addressed QOL in female cancer survivors in Africa. The extent to which QOL studies incorporated a cultural perspective was also examined. Research studies published between 2005 and 2015 were retrieved from five databases: CINAHL, MEDLINE, SCOPUS, ProQuest dissertations and Theses full text, and GlobalHealth...
