Small increases or 'blips' in HIV levels do not signal mutations leading to drug-resistant HIV
...ns were found in an analysis of nearly 1,000 viral clones for mutations in HIV's two key enzymes which are blocked by drug therapy, protease and reverse transcriptase. The authors also found that blips were not, again, detected when blood samples were assayed twice in independent laboratories.

"From an immunologist's standpoint, TB is a really challenging disease to work on because we need to understand how the cellular system works in order to create better vaccines," David...Reprogrammable cells from fat are true adult stem cells

The ability to track the spread of individual strains is made possible by using techniques like Pulsed Field Gel Electrophoresis (PFGE) and ......ported in article #6000, indicate that the T cells clones were able to home in on the tumors, which regressed slightly or stabilized in 8 of the 10 patients, for an average period of 11 months. In addition to T cells, the injections contained IL-2, a chemical that stimulates the T cells to replicate, resup...
