The infection of human immunology viruses (HIV) occurs by integrating its genome into infected cells to enter an inactive state of reversible latency that evades anti-retroviral therapy. The capacity to sequence such a provirus ...
A team of researchers from the U.K., Denmark, Poland, the Netherlands and Switzerland has developed a new way to test for cancer—by looking at the size of tumor DNA fragments circulating in the bloodstream. In their paper ...
(Medical Xpress)—The importance of the bacteria that live within our digestive tracts is just beginning to be fully realized, and while it has long been known that they assist in digestion and absorption of nutrients, little ...
A new study led by scientists from the Lawrence Berkeley National Laboratory (Berkeley Lab) found that a healthy intake of micronutrients is strongly associated with improved sperm DNA quality in older men. In younger men, ...
