Statins, the cholesterol-lowering drugs that protect against heart attacks and strokes by lowering cholesterol, may also protect against age-related memory loss and dementia, a new study finds.

Researchers from the University of Michigan School of Public Health analyzed health records of about 1,700 elderly Mexican-Americans who took cholesterol-lowering statin drugs for five years

Parents who care for mentally-challenged children are prone to develop weak immune systems due to stress, new research suggests. The study concluded that such parents should be offered a better support system.

Researchers at Birmingham University analyzed 60 parents who received the pneumococcal vaccine as part of the study. Half of them had children with developmental disabilities

Researchers have developed a tobacco plant-based vaccine for patients with a chronic form of lymphoma, a specific type of cancer.

According to the first human study of the approach, researchers found that the vaccine could trigger an immune response in the body, which could lead to personalized vaccines that may kick start the patients' immune systems to attack the cancer

Researchers have achieved a breakthrough in growing functional human blood vessels in mice using cells from adult human donors. The achievement is seen as an important step in developing clinical strategies to grow tissue vessels that may one day deliver oxygen-rich blood to damaged organs.

Researchers withdrew stem cells from the blood or bone marrow of adults or the umbilical cord blood of newborns. The cells were combined with two different types of progenitor cells in a culture dish of nutrients and growth factors. The cells were then implanted into mice with weakened immune systems

Older women who either sleep too much or too little are at a greater risk of suffering from stroke, a new study shows. Researchers found that habitual sleep patterns in postmenopausal women could be important in determining the risk of ischemic stroke.

Researchers from Albert Einstein College of Medicine in New York City studied 93,676 postmenopausal women and found that those who regularly slept nine hours or more were 70 percent more likely to have an ischemic stroke, compared with women who slept seven hours a night
