Common cardiac sodium channel variant associated with sudden infant death in African Americans

Steve A.N. Goldstein and colleagues from the Pritzker School of Medicine in Chicago have found that a specific mutation, called S1103Y, in a heart protein known as SCN5A is associated with a dramatic, 24-fold increased risk of sudden infant death syndrome (SIDS) in African American infants.

Can marriages be saved by treating snoring?

The husband snores. The wife nudges him to flip over. Both wake up feeling grouchy the next morning. It's a common occurrence that may have more of an impact on the marriage than most couples think.

First description of female-specific Ischemia Syndrome

Although ischemic heart disease - the reduction of blood flow that can lead to heart attacks - is often considered a "man's disease," it takes the lives of more women than men each year. In fact, in 2000, about 60,000 more women than men died from cardiovascular disease.

Diabetic heart muscle makes heart disease the most common killer of diabetics

The high-fat "diet" that diabetic heart muscle consumes helps make cardiovascular disease the most common killer of diabetic patients, according to a study done at Washington University School of Medicine in St. Louis.

Phase II clinical trial for new gene transfer drug study

As many as 8-10 million Americans have Peripheral Artery Disease (PAD), by age 70, roughly 20 percent of the population has it, and people with PAD face a six-to-seven times higher risk of heart attack or stroke.

Angina drug finally gets the ok

U.S. regulators have granted approval for the drug Ranexa in the treatment of chronic angina.

University of Florida researchers restore vitality to cells in lab experiments

University of Florida researchers say primitive cells that act like molecular maintenance men - traveling throughout the body to repair damaged blood vessels - become too rigid to move in patients with diabetes, fueling the disease's vascular complications.

New insights into tube size morphogenesis

The function of tubular organs like the kidneys, lungs, and vessels of the vascular system is critically dependent on the length and diameter of the tubular branches of which they are composed.

First-of-its-kind study in heart attack patients seeks to prevent heart failure with stem cells

University of Rochester Medical Center researchers have announced the launch of a study that will examine whether transplanted stem cells can be safely used to treat damaged heart muscle in patients just after their first heart attack.

Histidine may be key to new therapies for cardiovascular disease

It's just one little amino acid, but it makes all the difference in protecting the heart from the harmful effects of heart attack and cardiac failure. Researchers from the University of Michigan Medical School suggest this amino acid, called histidine, could be the key to a new therapy for cardiovascular disease

Coffee may impair peak heart function

In healthy volunteers, the equivalent of two cups of coffee reduced the body's ability to boost blood flow to the heart muscle in response to exercise, and the effect was stronger when the participants were in a chamber simulating high altitude, 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.

Sickle cell corrected with gene copy

Scientists in the U.S. say they have found a way to use embryonic stem cells to correct the mutation that causes sickle cell disease in mice.

Administering stem cells to patients with myocardial infarction leads to a reduction of the size of the infarct

This week, doctors at the Catholic University of Leuven, connected with the University Hospital - Gasthuisberg, the Stem Cell Institute Leuven (SCIL), and the Flanders Interuniversity Institute for Biotechnology (VIB), are publishing a major breakthrough in the treatment of patients with acute myocardial infarction.

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.

Exercise helps elderly heal

The body's ability to heal even small skin wounds normally slows down as we age. But a new study in older adults finds that regular exercise may speed up the wound-healing process by as much as 25 percent.

Hyperbaric oxygen treatments mobilizes stem cells aiding injury repair

According to a study to be published in the American Journal of Physiology-Heart and Circulation Physiology, a typical course of hyperbaric oxygen treatments increases by eight-fold the number of stem cells circulating in a patient's body.

Electrical microstimulation allows researchers to map the brain for the first time

Over the last two centuries electrical microstimulation has been often used to demonstrate causal links between neural activity and specific behaviors or cognitive functions. However, to understand the mechanisms by which electrical microstimulation can cause alternations in behaviors and cognitive functions it is imperative to characterize the cortical activity patterns that are elicited by stimulation locally around the electrode and in other functionally connected areas.
