Aims: Alcoholism may be a cardiovascular risk factor. Osteocyte derived molecules such as fibroblast growth factor 23 (FGF-23) and soluble α Klotho have recently been associated with cardiovascular disease, but their role in alcoholics is unknown. We here analyze the behavior of FGF23 and α Klotho in alcoholics. Methods: Ninety-seven alcoholic patients were assessed for liver function, presence of hypertension, diabetes, atrial fibrillation, left ventricular hypertrophy (LVH), vascular calcifications (assessed by chest X-ray) and nutritional status (lean and fat mass measured by densitometry)...

BACKGROUND AND AIMS: Hyperhomocysteineamia (HHcy) has long been suggested as a risk factor for atherosclerosis. However, the association between HHcy and peripheral arterial disease (PAD) is still controversial. There is a lack of research on this topic in the Chinese population. This study aims to provide further results. METHODS: 240 PAD patients and 240 control subjects were evaluated for both serum total homocysteine levels and ankle brachial indexes (ABIs)...

The role of sex in biomedical studies has often been overlooked, despite evidence of sexually dimorphic effects in some biological studies. Here, we used high-throughput phenotype data from 14,250 wildtype and 40,192 mutant mice (representing 2,186 knockout lines), analysed for up to 234 traits, and found a large proportion of mammalian traits both in wildtype and mutants are influenced by sex. This result has implications for interpreting disease phenotypes in animal models and humans.

Young men who have sex with men (YMSM) have high rates of recreational drug use and binge drinking that are related to increases in unprotected sex and HIV risk. We describe the development of a community-level intervention focused on MSM ages 15 to 29 who identify as Black or White and who reported episodic use of alcohol and/or drugs. Intervention content included culturally-relevant role model stories and peer outreach. Outcome measures, including number of partners and a risk score indicating risk for HIV from protected or unprotected insertive or receptive anal sex, were examined over 36 months in a sample of YMSM in Philadelphia, the intervention site, and Baltimore, the comparison site...

Steroids are neuroprotective and growing body of evidence indicates that mitochondria are a potential target of their effects. The mitochondria are the site of cellular energy synthesis, regulate oxidative stress and play a key role in cell death after brain injury and neurodegenerative diseases. After a summary of the literature on the general functions of mitochondria and the effects of sex steroid administrations on mitochondrial metabolism, we will summarize and discuss our recent findings concerning sex differences in brain mitochondrial function in physiological and pathological conditions...

OBJECTIVE: Lower body fat is associated with diminishing cardiometabolic risk. Physiological differences between gluteofemoral and abdominal subcutaneous adipocyte functions are known, but the molecular basis for depot differences in adipocyte function is poorly understood. The objective of this study was to identify depot differences in microRNA (miRNA) expression in human abdominal and gluteofemoral subcutaneous adipose tissues and their implication in gene regulation. METHODS: Abdominal and gluteofemoral adipose tissue aspirates obtained from 18 participants (9 male and 9 female, age 30 ± 1...

BACKGROUND: Little is known about the role of dietary intake in obstructive sleep apnea (OSA), which could prove important in improving clinical outcomes for people with obesity and/or cardiovascular disease within these populations. Reduction in energy intake typically results in weight loss, markedly improving metabolic parameters and ameliorating OSA severity. The aim of this study was to evaluate the association of dietary and cardio-metabolic risk factors with OSA severity. METHODS: This was a cross-sectional study...

Sexual dimorphism in immune response is widely recognized, but few human studies have observed this distinction. Food with endo-immunomodulatory potential may reveal novel sex-biased in vivo interactions. Immunomodulatory effects of Carica papaya were compared between healthy male and female individuals. Volunteers were given fixed meals supplemented with papaya for 2 days. Changes in blood immune profiles and hormone levels were determined. In females, total natural killer (NK) cell percentages decreased (12...

Quantitative as well as qualitative bone loss occurs with aging in both men and women, leading to alterations in skeletal microarchitecture and increased fracture incidence. Sex steroids, primarily estrogen and testosterone, have been shown to play a central role in the aging process of bone. The relationship between diminishing estrogen levels in women caused by ovarian failure and the development of postmenopausal osteoporosis is widely recognized. Unexpectedly, bone mineral density at various skeletal sites in men is also better correlated with circulating levels of bioavailable estrogen than with testosterone...

In zebrafish, there exists a clear need for new tools to study sex differentiation dynamic and its perturbation by endocrine disrupting chemicals. In this context, we developed and characterized a novel transgenic zebrafish line expressing green fluorescent protein (GFP) under the control of the zebrafish cyp19a1a (gonadal aromatase) promoter. In most gonochoristic fish species including zebrafish, cyp19a1a, the enzyme responsible for the synthesis of estrogens, has been shown to play a critical role in the processes of reproduction and sexual differentiation...

Maternal diabetes programs metabolic and cardiovascular diseases in the offspring. Here, we demonstrated increased pro-oxidant/pro-inflammatory markers in the heart of 2-day-old offspring of diabetic rats, previous to the induction of metabolic alterations. At a pre-pubertal stage, sex-dependent changes were evidenced in the diabetic group, as only males showed increased glycemia as well as increased lipoperoxidation and concentrations of nitrated proteins, matrix metalloproteinase-9 and peroxisome proliferator activated receptor α (PPARα) in the heart...

Female sex workers (FSWs) are disproportionately affected by HIV, but there is limited research on their HIV care experiences. This study explored the experiences of 44 FSWs living with HIV in Santo Domingo, Dominican Republic along the HIV care continuum using in-depth interviews and focus groups. Data were analysed through narrative and thematic analysis. Individual-level factors that facilitated engagement in HIV care were physical and mental health. At the interpersonal level, disclosure of HIV or sex work status and receipt of emotional and economic support were important influences on engagement...

The World Professional Association for Transgender Health (WPATH) defines gender dysphoria as "Discomfort or distress that is caused by a discrepancy between a person's gender identity and that person's sex assigned at birth (and the associated gender role and/or primary and secondary sex characteristics)" (WPATH, 2016). Gender creative (GC) and transgender (TG) youth are at high risk for severe mental health disparities if they don't receive competent and timely gender transitioning care. Although awareness and early care of TG youth in specialty clinics is improving and increasing, there is still much effort that is required to eliminate barriers to care at many levels and thus improve outcomes...

Calsyntenin-2 (Clstn2) is the synaptic protein that belongs to the super family of cadherins, playing an important role in learning and memory. We recently reported that Clstn2 knockout mice (Clstn2-KO) have a deficit of GABAergic interneurons coupled with hyperactivity and deficient spatial memory. Given, that impaired functioning of GABA receptors is linked to several psychopathologies, including anxiety and autism, we sought to further characterize Clstn2-KO mice with respect to emotional and social behavior...

BACKGROUND: Placental Growth Factor (PGF) is important for wound-healing and vascular collaterogenesis. PGF deficiency is associated with preeclampsia, a hypertensive disease of human pregnancy. Offspring born to preeclamptic mothers display cognitive impairments and brain vascular and neurostructural deviations. Low PGF production during development may contribute to alterations in offspring cerebrovascular beds. Retina is a readily accessible part of the central nervous system with a well-described pattern of vascular development in mice...

Females show a varying degree of ischemic sensitivity throughout their lifespan, which is not fully explained by hormonal or genetic factors. Epidemiological data suggest that sex-specific life experiences such as pregnancy increase stroke risk. This work evaluated the role of parity on stroke outcome. Age-matched virgin (i.e., nulliparous) and multiparous mice were subjected to 60 min of reversible middle cerebral artery occlusion and evaluated for infarct volume, behavioral recovery, and inflammation. Using an established mating paradigm, fetal microchimeric cells present in maternal mice were also tracked after parturition and stroke...
