Adults over 70 with higher levels of education forgot words at a greater rate than those with less education, according to a new study from the University of Southern California. The findings, published in the current issue of Research on Aging, suggest that after age 70, educated adults may begin to lose the ability to use their schooling to compensate for normal, age-related memory loss.
Advances in medical technology are a main factor driving the trend of increasing health-care costs, and industry stakeholders agree that improved evaluation methods are needed to better measure the benefits and risks of new technologies and procedures in order to avoid misallocation of health-care dollars.
Answering one of the oldest questions in human physiology, researchers at Dana-Farber Cancer Institute have discovered why the body’s immune system — perpetually on guard against foreign microbes like bacteria — doesn’t attack tissues in the small intestine that harbor millions of bacteria cells.
Researchers at the University of Southern California (USC) recently made significant strides toward settling a decades-old debate centering on the role played by stem cells in cancer development. According to the study’s findings, which appear in an upcoming issue of Nature Genetics and now available online, genes that are reversibly repressed in embryonic stem cells are over-represented among genes that are permanently silenced in cancers; this link lends support to the increasingly discussed theory that cancer is rooted in small populations of stem cells.
The longer Black Caribbean immigrants stay in the U.S., the poorer their mental health becomes. That?s one finding from a new study that examined the prevalence of psychiatric disorders among Black individuals in the U.S. The study appears in the January 2007 issue of the American Journal of Public Health.
Scientists have discovered a new source of stems cells and have used them to create muscle, bone, fat, blood vessel, nerve and liver cells in the laboratory. The first report showing the isolation of broad potential stem cells from the amniotic fluid that surrounds developing embryos was published today in Nature Biotechnology.
A preliminary study suggests there may be hope in the offing for some sufferers of chronic fatigue syndrome with a new therapy being tested by researchers at the Stanford University School of Medicine.
Scientists at the University of Liverpool have found how two molecules fight in the blood to control the spread of cancer cells.
University of Pittsburgh investigators have successfully prevented the onset of type 1 diabetes in mice prone to developing the disease using an antibody against a receptor on the surface of immune T-cells. According to the investigators, these findings, which are being published in the January issue of the journal Diabetes, have significant implications for the prevention of type 1 diabetes.
Dartmouth Medical School researchers have identified a new way that arsenite, a form of arsenic, acts in treating a rare cancer known as APL, or acute promyelocytic leukemia. Their study is published in the Jan_3 issue of the Journal of the National Cancer Institute.
