Edible bivalves as a source of human pathogens: signals between vibrios and the bivalve host.

Clams, mussels and oysters are important vehicles for the transmission of enteric diseases when consumed raw or undercooked. Vibrio species, including human pathogens, are particularly abundant in bivalve tissues, where they can persist even after cleaning procedures, thus representing a potential risk for human health. Although different environmental factors are well known to affect the persist...

Bone and cartilage growth to blame for heart valve disease

Research to be published in the April 18 issue of the Journal of the American College of Cardiology provides the first explanation of an active rather than passive process that leads to heart valve degeneration, furthering a Northwestern researcher's effort to lead a paradigm shift in the medical community's beliefs about the cause of valve disease. Heart valve disease is caused not by a '...

Percutaneous aortic valve replacement safe, successful in high-risk patients

Catheter techniques are expanding into new territory, successfully aiding in the replacement of narrowed, calcified aortic valves in patients too sick to withstand open-chest surgery. According to a study reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI), May 9?2, 2007, in Orlando, FL, patients who were treated with the CoreValv...

Defective heart valve causes problems

According to researchers, a recent study shows that a leaky heart valve raises the risk of abnormal heart rhythms. In atrial fibrillation (AF) the upper chambers of the heart beat randomly and unsuccessfully. The condition is linked to heart attack and stroke.// Researchers at the University of Texas, have now shown that having a leaky heart valve - separating the upper and lower heart chambers...

Cardiac Valve Disease Linked To Genes

A new study suggests that death from cardiac valve disease might be predominant in certain families. Researchers analyzed // death certificates and genealogy data of people who died of aortic and mitral valve disease . Results show deaths from nonrheumatic mitral and aortic diseases are clustered among close and distant relatives, which suggests a genetic link. Deaths from these condit...

Mutations in NOTCH1 cause an early developmental defect in the aortic valve

Dr. Srivastava and his colleagues of UT Southwestern Medical Center of Dallas// discovered that the mutation in a gene NOTCH1 is responsible for aortic valve disease. Aortic valve disease is a common heart birth defect which causes adult heart disease. The study was done in five generations of a Dallas family; the researchers studied the DNA mutations in all the 11 members of the family...

Heart valve surgery may be replaced by new heart therapy

The most common heart problems among the old people are those involving the mitral valve(that which controls the flow of blood between the two left chambers of the heart) and the aortic valve(that which controls the flow of blood into the heart). Until now, surgeons surgically replaced the damaged valve in these patients by opening the breast bone. However, a recent discovery// of a new procedure...
