Thiamin supplements may help protect heart failure patients

Among patients hospitalized with heart failure, about one in three has deficient levels of thiamin, although thiamin deficiency was less common among those patients who were taking vitamin supplements, according to a new study in the Jan. 17, 2006, issue of the Journal of the American College of Cardiology.

Acetazolamide improves central sleep apnea in heart failure

Since sleep apnea is associated with heart failure, patients who take a single dose of acetazolamide - a mild diuretic and respiratory stimulant - before going to bed exhibit less sleep apnea, improved blood oxygen levels and fewer daytime symptoms of sleepiness.

Molecular disruption of hypothalamic nutrient sensing induces obesity

In their latest finding on the brain's role in controlling appetite and weight, researchers at the Albert Einstein College of Medicine have shown that reducing levels of fatty acids in the hypothalamus causes rats to overeat and become obese. Their results suggest that restoring fatty-acid levels in the brain may be a promising way to treat obesity.

Cut calories, cut portions for a younger healthier heart

According to a new study, which is the first to associate calorie restriction with delaying the onset of aging, cutting down on calories and restricting portions, really does work.

Tomato juice keeps emphysema from developing in new animal model of degenerative disease

Feeding tomato juice to mice kept them from developing emphysema after cigarette smoke exposure that was long enough to induce emphysema in a control group, Japanese researchers report in February issue of the American Journal of Physiology-Lung Cellular and Molecular Physiology.

Loyola to study for first time IV medication for osteopenia and inflammatory bowel diseases

Researchers at the Osteoporosis and Metabolic Bone Disease Center and the Division of Gastroenterology at Loyola University Health System are studying a once-yearly, 15-minute infusion of an intravenous (IV) medication in patients with osteopenia (low bone mass) and inflammatory bowel diseases (IBD) that, if proven effective, may be considered the standard of treatment.

Astrocytes play a direct role in controlling blood flow in the brain - influencing Alzheimer's

New findings that long-overlooked brain cells play an important role in regulating blood flow in the brain call into question one of the basic assumptions underlying today's most sophisticated brain imaging techniques and could open a new frontier when it comes to understanding Alzheimer's disease.

UCLA examines disease-versus-disease interactions

The knowledge that one disease may prevent the onset of another is not new. For example, the discovery that cowpox vaccines can prevent smallpox dates back to 1798.

New human embryonic stem cells grown in animal cell-free cultures

Scientists working at the WiCell Research Institute, a private laboratory affiliated with the University of Wisconsin-Madison, have developed a precisely defined stem cell culture system free of animal cells and used it to derived two new human embryonic stem cell.

Eating disorders linked to perinatal complications

Certain complications during and immediately after birth are associated with the development of the eating disorders anorexia nervosa and bulimia nervosa, according to a study in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

University of Michigan Medical School to study the science of obesity and metabolism

As millions of Americans prepare their New Year’s resolutions to lose weight, eat better or exercise more, the University of Michigan Medical School is launching a new center that may help explain why so many resolutions fail, while others succeed.

Diet rich in antioxidants protects against Age-Related Macular Degeneration

New research has shown that a diet high in beta carotene, vitamins C and E, and zinc is associated with a substantially reduced risk of age-related macular degeneration in elderly people.

Understanding obesity in humans

A new study by researchers at UT Southwestern Medical Center suggests that when fat cells increase in size - as they do during the development of obesity - the cells progressively lose receptors for the hormone leptin, a powerful stimulus for fat burning.

Suddenly sugar isn't looking so sweet

University of Florida researchers have identified one possible reason for rising obesity rates, and it all starts with fructose, found in fruit, honey, table sugar and other sweeteners, and in many processed foods.

New door opens for anti-aging research in humans

A counterintuitive experiment has resulted in one of the longest recorded life-span extensions in any organism and opened a new door for anti-aging research in humans.

Diets rich in meat increase the likelihood of developing chronic respiratory symptoms

A new study finds that eating mostly meat, refined starches, and sodium may increase the likelihood of developing chronic respiratory symptoms, including chronic obstructive pulmonary disease (COPD).

New genes that regulate longevity

In an effort to understand the molecular mechanisms that control aging, Howard Hughes Medical Institute researchers and their colleagues have now uncovered 10 new genes that regulate longevity in yeast. The studies also suggest a new model for how aging is slowed when caloric intake is restricted.

Biologically engineered blood vessels now an option in cardiac bypass

The first-ever human use of completely biologically engineered blood vessels grown from a person's own cells could be an option for people who have vessels too damaged for heart bypass, researchers reported at the American Heart Association's Scientific Sessions 2005.

Gene therapy potential of the protein vasostatin for treatment of pancreatic cancer

A gene responsible for the production of a protein called vasostatin may prove a promising new way of treating pancreatic cancer, suggests research published ahead of print in Gut.
