Loss of stem cells correlates with premature aging in animal study
... To be able to renew itself, most tissues have a reservoir of specific adult stem cells. These stem cells dont divide as frequently as other cell types since they need to maintain the integrity of their DNA, and multiple divisions lead to natural breaks in DNA. But when these stem cells are needed, their pro...Vacuum cleaning ineffective in allergy avoidance
... Sercombe said that given that carpets are a major reservoir of dust mite allergen and vacuum cleaning is the most common method of allergen control, the results are particularly relevant to professionals interested in limiting people's exposure to common allergens. "The results also help to explain why man...The quest for an effective HIV vaccine presents new possibilities, challenges
...but, unlike HIV, most do not establish a permanent reservoir of infected cells in the body. The window of opportunity to prevent long-term HIV infection may close permanently once a pool of latently infected cells is in place, Drs. Johnston and Fauci note.

...dy suggests that removal of the nodes takes away a reservoir for potentially lethal cancer, and that knowing how far a cancer has spread leads to tailored and more beneficial treatment, according to researchers at The University of Texas M.

... researchers' findings showed that there remains a reservoir of aberrant cells that cause the disease to reappear if therapy is stopped. Thus, he said, he and his colleagues are working to understand those cells and how to eradicate them to ultimately cure the disease.

...researchers have found the human gut to be a major reservoir harboring the HIV virus -- holding almost twice as much as a person's blood. In addition, the virus stored in the gut does not decay or reduce over time, as is also the case with blood-related reservoirs. It is well-known that peripheral blood mononu...Sandia work launched on space shuttle shows live cells influence growth of nanostructures

...eatment of people with latent infection, who are a reservoir for future cases, will be key. However, the standard diagnostic test for latent TB--the century-old tuberculin skin test--is unreliable, often producing false negative results in high-risk groups and false positives in others, such as those who have ...How can we protect patients with weakened immune systems from influenza?
...eople with healthier immune systems, they may be a reservoir for the disease. In addition to the yearly toll of ordinary influenza (as many as 36,000 annual fatalities in the U.S.), added concerns over potential threats -- an avian flu pandemic or the use of flu as a weapon of biological warfare -- put anti-fl...Multiple sclerosis research into reparative cells offers new avenue for fighting disease
...h the oligodendrocytes are damaged, there exists a reservoir of oligodendrocyte precursor cell, or OPCs, left over from development that could be activated to repair the damage, he said.
