In a study, a new HIV drug reduced viral replication and increased immune cells in individuals with advanced, drug-resistant HIV infection.

Differing levels of sex hormones, especially estrogens, may explain why many more women than men suffer from migraines. A study published today provides evidence that these hormones affect cell mechanisms that control responses to migraine triggers, offering a possible pathway to more effective, personalized treatments.
Researchers from Brighton and Sussex Medical School have found an unexpectedly close link between a herpes virus and the occurrence of immune cells damaging cardiovascular tissue.
Estrogen may protect against heart failure-related depression by preventing the production of inflammation-causing chemicals in the brain. The study is published ahead of print in the American Journal of Physiology - Heart and Circulatory Physiology.
Brandon Brown, an HIV researcher at the University of California, Riverside's School of Medicine, is the lead author on a study published today in the journal Medicine, in which he and his co-authors argue that interventions are urgently needed to reach older adults and Hispanics to address HIV testing and beliefs.
Transgender individuals may be at higher risk for heart disease, according to a review article published by Michael S. Irwig, M.D., associate professor of medicine at the George Washington University School of Medicine and Health Sciences, in Reviews in Endocrine and Metabolic Disorders.
Scientists once thought that female mate choice alone accounted for the eye-catching color patterns seen in some male fish. But for orangethroat darters, male-to-male competition is the real force behind the flash, a new study finds.
In the largest study of its kind to report differences in physical activity and obesity by sex and sexual orientation, obesity was more likely among lesbian, bisexual and questioning female youth than heterosexual female peers. Additionally, lesbian, gay, bisexual and questioning youth are more likely to develop Type 2 diabetes, be obese and engage in less physical activity and more sedentary activities than heterosexual youth.
A world-first study by QUT researchers concludes men can and do suffer from postcoital dysphoria (PCD) which results in feelings of sadness, tearfulness or irritability following sex. Masters student Joel Maczkowiack and Professor Robert Schweitzer from QUT's School of Psychology and Counselling said that while the condition had been recognized in women, no studies had previously identified the phenomenon among males.
The disparity between the number of sexual partners reported by men and women can largely be explained by a tendency among men to report extreme numbers of partners, and to estimate rather than count their lifetime total, a new study in The Journal of Sex Research finds.
