Findings may contribute to improved education and preventive efforts to help control the spread of sexually transmitted infections.
Studies have shown women are more risk-averse than men, a trait experts say could help to explain the persistent wage gap between men and women. New research suggests those gender differences are shaped by culture and the social environment and that those differences can shift, at least in children.
In the largest such study so far undertaken, US researchers have shown that testosterone replacement slows the recurrence of prostate cancer in low-risk patients. This may call into question the general applicability of Nobel-Prize winning hormonal prostate treatment. The work is presented at the European Association of Urology congress in Barcelona.
An international team of researchers presents a comprehensive and renewed focus on the common, yet poorly understood condition of bacterial vaginosis (BV) and how the microbial make-up of the vagina can affect a woman's risk of acquiring HIV and AIDS.
Lucie Cluver, Professor of Child and Family Social Work in Oxford's Department of Social Policy and Intervention, is the principal investigator and lead author with Mark Orkin, Visiting Professor in the Developmental Pathways to Health Research Unit (DPHRU) in the Department of Paediatrics & Child Health, School of Clinical Medicine at Wits University.
Women who get pregnant while using birth control may carry a gene that breaks down the hormones common in contraceptives, according to researchers at the University of Colorado Anschutz Medical Campus.
More than 30 years ago, scientists discovered that mad cow and Creutzfeldt-Jakob diseases are caused by prions. But in recent years, Nobel laureate Eric Kandel, M.D., demonstrated in mice that some prions are beneficial and serve important functions in the brain and body. And today, new Columbia research from Dr. Kandel describes how one such prion-like protein helps the brain keep fearful memories in check. Without it, female mice exhibit the tell-tale signs of post-traumatic stress disorder, or PTSD.
Researchers at the University of New Hampshire are one step closer to helping answer the question of why autism is four times more common in boys than in girls after identifying and characterizing the connection of certain proteins in the brain to autism spectrum disorders (ASD).
Results from largest ever HIV prevention trial suggest strategy could make a significant contribution to controlling epidemic.
Findings from HPTN 071 (PopART) show delivery of an HIV prevention strategy that includes offering in-home HIV testing to everyone, with immediate referral to HIV care, and treatment for people living with HIV based on prevailing in-country guidelines, can substantially reduce new HIV infections.
