It?s yet another example of how a good thing can go bad: Researchers have found evidence in laboratory studies that ?good? cholesterol, renowned for its ability to protect against heart disease, can undergo detrimental changes in protein composition that make it ?bad? for the heart.
New research by scientists in Taiwan has shown that an 800-year-old formula, Four-Agents Decoction (Si Wu Tang), does not significantly reduce menstrual pain after three cycles of treatment; however, a beneficial effect may be present after a longer treatment.
Groundbreaking research from the University of Melbourne has shed new light on why long term drug users find it hard to say no, despite dire consequences to their health.
A collaborative team of scientists reported findings demonstrating the presence of Marburg virus RNA genome and antibodies in a common species of African fruit bat (Rousettus aegyptiacus).
If you think the big cities of Toronto and Montreal have the highest rate of alcohol and drug use problems, think again.
