Ever since vitamin C was found to prevent scurvy -- a disease that has killed millions of people throughout history -- scientists have known that the vitamin plays an essential role in the body's defense against disease. Immune cells, for example, are known to accumulate and retain high levels of vitamin C, but just how this process occurs, has largely remained a mystery.
Fewer than half of the patients under treatment for schizophrenia are receiving proper doses of antipsychotic medications or appropriate psychosocial interventions, according to a national study funded by the Agency for Health Care Policy and Research and the National Institute of Mental Health (NIMH). The study identified gaps in effective care for people with schizophrenia and opportunities for improvement in all aspects of treatment.

The cholesterol-lowering effect of soy is the result of natural compounds in the soy known as isoflavones, Wake Forest University Baptist Medical Center researchers reported today at an American Heart Association meeting in Santa Fe, NM. John R. Crouse III, M.D., said the project was the first to dissect the effects of isoflavones in soy from the overall soybean.
Postmenopausal hormone replacement therapy markedly reduces the occurrence of atherosclerosis in the internal carotid artery in monkeys, a Wake Forest University Baptist Medical Center research team reported today. Hormone replacement therapy from soy protein with phytoestrogens provided equivalent stroke-prevention benefits to the standard Premarin therapy prepared from mammalian estrogens.
Soy proteins contain "phytoestrogens" -- biochemical cousins of the female hormone that are a possible alternative therapy to protect against artery disease. In a new 3-year study, postmenopausal cynomolgus monkeys were fed an artery disease-causing diet.
Adding more fuel to this ongoing research debate is a new analysis by the Los Angeles Atherosclerosis Study: Data from 577 symptom-free utility workers age 40 to 60 show a "significant" relation between total alcohol intake and fractionally less thickness of the wall of the large carotid artery in the neck -- but only in women.
