For years, physicians have told patients that HDL (high-density lipoprotein cholesterol) helps protect them from cardiovascular disease (CVD). And the higher the number, the more the protection. HDL, often considered an independent predictor of heart disease, has been dubbed the "good" cholesterol, thanks to its protective effects. But a new study shows for the first time that HDL's protection depends on the levels of two other blood fats or lipids associated with heart disease. If these fats are not within normal ranges, even a high HDL may not be protective.

In a study of nearly 650 people with the eye disease age-related macular degeneration (AMD), half still had vision 20/40 or better, typically good enough to drive or to read standard print, after five years of treatment with anti-VEGF drugs that are injected into the eye. The authors of the study, funded by the National Eye Institute (NEI) at the National Institutes of Health, say those outcomes would have been unimaginable about 10 years ago, prior to the drugs’ availability.

The constant emergence of viral outbreaks has become a permanent threat to human health. Last year, Zika virus infected thousands of people in the Americas. It is also associated to several cases of neurological disorders and has raised worldwide public health alerts. Now due to the urgency, researchers are detailing the characteristics of the virus to find solutions.

Probiotic supplements protected female mice from the loss of bone density that occurs after having their ovaries removed, researchers at Emory University School of Medicine and Georgia State University have shown.The results were published Monday, April 25 in Journal of Clinical Investigation.

Researchers have identified a molecular marker that identifies proliferating cells in normal breast tissue and can predict a woman's risk of developing breast cancer, the leading cause of death in women with cancer worldwide.

Scientists have developed a structure-based vaccine design that can jumpstart an effective immune response to HIV by rapidly offsetting antibodies against the virus, which so far have been unsuccessful.

Countries with higher male smoking rates such as India and Bangladesh can push up asthma and wheezing cases as a result of more exposure to second-hand smoke.This is what Jayadeep Patra, an epidemiologist at the Centre for Global Health Research at St. Michael's Hospital in Toronto, says.
