Tissues derived from embryonic stem cells could help to pacify the immune system and so prevent recipients from rejecting them.

Wine may protect against dementia. A study looked at 1,458 women over a long period of time. After 34 years, 162 women had been diagnosed with dementia. The results show that among those women who reported that they drank wine a considerably lower proportion suffered from dementia, whereas this correlation was not found among those who had reported that they regularly drank beer or liquor.

Researchers who have followed 5,840 people from before birth to the age of 31 have found evidence suggesting that small size at birth and excessive weight gain during adolescence and young adulthood may lead to low grade inflammation, which, in turn, is associated with an increased risk of developing heart disease. The study underlines the important role of healthy lifestyles, from the fetal period, through childhood, adolescence and young adulthood, in preventing heart problems.

In a finding that challenges conventional medical knowledge, researchers report that plaques formed in during atherosclerosis, or hardening of the arteries, are associated with certain harmful chemical reactions that can contribute to damage in the lungs, liver and other organs. The study suggests that the effects of the disease are more widespread than previously believed.

Combining two targeted therapies overcomes treatment resistance in liver cancer cell lines, new research shows. Liver cancer is resistant to many chemotherapies and to cell-death inducing agents.

Researchers have found that a tumor protein present in an aggressive form of breast cancer is related to a poor prognosis. The presence of the protein, called growth factor receptor-bound protein-7, often referred to as GRB-7, in breast cancer tumors, is strongly related to the growth and spread of the cancer, according to investigators.

The discovery of a gene for a rare form of inherited iron deficiency may provide clues to iron deficiency in the general population -- particularly iron deficiency that doesn't respond to iron supplements -- and suggests a new treatment approach.

Researchers have established necrostatins as the first-in-class inhibitors of RIP1 kinase, a protein that can direct cells into necrotic death. The findings appear to provide a new avenue for drug development to prevent cell death related to acute disease events such as heart attack and stroke.

Smoking puts older women at significant risk for loss of DNA repair proteins that are critical for defending against development of some colorectal cancers, according to new research.

Prostate tumors grew more quickly in mice who exercised than in those who did not, leading to speculation that exercise may increase blood flow to tumors, according to a new study. The researchers want to caution men against interpreting these findings as an endorsement for not exercising for fear of getting or exacerbating cancer.
