A study found that fiber supplements containing psyllium can lower harmful cholesterol by up to 5%, reducing the risk of heart attack by 10-15%. The treatment is considered a viable alternative to cholesterol-lowering medications, especially for those who have difficulty tolerating statins.
A new study reveals that reprogrammed adult neural stem cells can differentiate into various cell types, including heart, liver, muscle, and intestine cells. This breakthrough adds to the growing evidence suggesting that adult stem cells may be more versatile than previously thought.
Researchers found that telomerase blocks a biochemical cascade of reactions called apoptosis, which causes nerve cell self-destruction. High levels of telomerase display remarkable resistance to damage or death in experimental models of Alzheimer's disease or stroke.
Researchers have identified over 2,000 genes active in blood stem cells, shedding light on how they replenish themselves and potentially inform treatments for diseases like leukemias. The discovery offers a powerful tool for understanding blood cell production and development.
Scientists at the University of Georgia discovered that Borrelia burgdorferi, the Lyme disease bacterium, can survive without iron. This finding may lead to new ways to prevent and control the disorder, as the bacterium's unique strategy could be used to limit its occurrence and severity.
