Sudden change in social status triggers genetic response in male fish, study finds
Throughout the animal kingdom, rival males routinely challenge one another for the right to reproduce. From the head-on collisions between bighorn rams to the ritualized wrestling matches of male rattlesnakes, combat is often the key to reproductive success. But now scientists studying a species of African cichlid fish have discovered that low-ranking male cichlids can quickly become lead...Researchers link two more genes to sudden infant death syndrome
Recent discoveries at Mayo Clinic added two more cardiac genes to the list of potential links to sudden infant death syndrome (SIDS), increasing the possibility that genetic defects of the heart may cause up to 15 percent of SIDS cases. This research will be presented Friday at Heart Rhythm 2006, the 27th Annual Scientific Sessions of the Heart Rhythm Society in Boston. In the two recent s...A potential biological cause for sudden infant death syndrome
New autopsy data provide the strongest evidence yet that sudden infant death syndrome (SIDS) is not a "mystery" disease but has a concrete biological basis. In the November 1 issue of JAMA, researchers at Children's Hospital Boston document abnormalities in the brainstem ?a part of the brain that regulates breathing, blood pressure, body heat, and arousal ?in babies who died from SIDS. S...Avoid sudden death by quick cooling
An emergency medicine expert said in New York on Thursday, at an American Medical Association press briefing on heart disease, that rapidly cooling people whose hearts have suddenly stopped, could provide a way to bring them back to life without organ damage. Dr. Lance B. Becker, Director of the Emergency Resuscitation Center at the University of Chicago said that thousands of people die...Fish Oil Fights Arrhythmias, Sudden Death
Daily supplements of a fatty acid found in fish oil halves the risk of sudden death in heart attack survivors. Previous research has found that eating oily fish such as tuna and salmon can reduce the risk// of sudden cardiac death caused by a particular type of irregular heartbeat. This study suggests fish-oil supplements, rather than dietary fish oil, could be a therapy without side effects for...Sudden Cardiac Death due to inherited Heart Disease
Unexplained sudden cardiac death is termed sudden arrhythmic death syndrome or SADS.Over 1,000 individuals die suddenly each day in the United States.// Most of these sudden deaths involve middle-aged or elderly individuals with heart problems. While sudden deaths in young people are rare, experts say they do have a tremendous impact on the medical community and the families. Previous...Vasopressin Found To Boost Survival In Sudden Cardiac arrest
Each year, more than 600,000 people die of sudden cardiac arrest in North America and Europe, usually because of // a heart attack or a heart rhythm disturbance. When medical personnel arrive, nearly 70 percent of victims have ventricular fibrillation, in which the heart's main pumping chambers flutter wildly and pump little blood. Less than 20 percent of these patients survive to go home....Vitamin E Could Restore Sudden Hearing Loss
A new study shows vitamin E may be effective in restoring sudden onset hearing loss. Researchers say sudden hearing loss, occurs within three days or less. The cause of the sudden hearing loss can be identified in only // 10 percent to 15 percent of the cases, which includes viral and bacterial diseases, and metabolic, neurologic and immunologic sources. The rest of the cases are termed idiopath...
