New Rochelle, NY, August 19, 2010 — The first successful report of using cell-depleted lung as a natural growth matrix for generating new rat lung from embryonic stem cells is presented in a breakthrough article in Tissue Engineering, Part A, a…
A diet rich in flaxseed seems to reduce the size, aggressiveness and severity of tumors in mice that have been genetically engineered to develop prostate cancer, according to new research from Duke University Medical Center. And in 3 percent of the mice, the flaxseed diet kept them from getting the disease at all. “The amount of flaxseed given to each mouse was 5 percent of its total food intake, which would be a very difficult amount for humans to eat,” said a lead researcher. “[B]ut it does signal that we are on the right track and need to continue research in this area.”
For the first time, researchers have demonstrated that exercise — without accompanying weight loss — has a positive impact on improving cholesterol levels. Further, they report that it is the amount of activity, and not necessarily any changes in fitness or intensity of exercise, that is important for cholesterol improvement. In the process of their studies, the researchers also demonstrated that the standard lipid panels used by doctors to measure the so-called “bad” LDL and “good” HDL forms of cholesterol do not necessarily provide the most accurate information in determining one’s risk of developing heart disease.
Researchers have detailed the functioning of an enzyme that is a central component of a signaling pathway important for about 30 percent of cancers. The findings about how the enzyme, called farnesyl transferase (FTase), works could help improve the FTase-inhibiting drugs that pharmaceutical companies are now testing to fight a broad spectrum of cancers.
