Adding beta-blocker metoprolol to standard treatment for heart failure increases survival by about 35 percent, according to a large international study. The study, called Metoprolol CR/XL Randomized Intervention Trial in Heart Failure (Merit-HF), was conducted in the US and 13 other countries.
A Cedars-Sinai Medical Center clinical trial may offer a permanent, non-surgical cure for patients with Paroxysmal Atrial Fibrillation. Correctly identifying patients and eliminating trigger areas using radiofrequency energy could eliminate the need for long-term therapy and reduce stroke risk.
Researchers at the University of Pennsylvania School of Medicine are studying how cells sense, respond, and adapt to physical forces. They aim to develop interventional drugs, gene-therapies, and blood-clot-dissolving enzymes for diseased vessels.
Researchers created P-cadherin-deficient mice to investigate the function of P-cadherin in controlling mammary tissue growth. The study found that P-cadherin plays a crucial role in maintaining undifferentiated breast tissue, and its absence leads to hyperproliferation.
A recent study by Daniel S. Kessler found that activation of siamois, a homeobox gene, is required for the formation of Spemann's organizer in frogs. The siamois gene is turned on by Wnt proteins and activates organizer genes, crucial for embryonic development.
Researchers used a novel test to measure damaging activity of free radicals in body tissues, finding high levels in atherosclerotic plaque tissue. The technique provides a real handle on oxidant processes in atherogenesis and could lead to clinical studies testing efficacy of drugs limiting free-radical damage.
A new multicenter randomized clinical trial aims to reduce stroke rates in African Americans by comparing the effectiveness of aspirin and ticlopidine. The study is supported by the National Institute of Neurological Disease and Stroke and will provide free medication to participants.
Electromyography has proven more reliable than high-tech diagnostic tools in pinpointing some back disorders, according to a researcher at the University of Michigan Medical Center. A new technique called mini-paraspinal mapping can accurately diagnose many back problems while reducing EMG needle insertions from 45 to 12.
A multicenter study found that antidepressant sertraline highly successful in treating premenstrual dysphoric disorder (PDD), with significant benefits seen in mood symptoms and relationship problems. The study showed 62% of women treated with sertraline experienced marked improvement, compared to 34% on placebo.
A study by the University of Pennsylvania School of Medicine found that postmortem sperm procurement requests are increasing, with over half made between 1994 and 1995. Most requests were from wives seeking to create children for their deceased husbands.
Researchers found that taking vitamins C and E before a high-fat meal can prevent impairment of blood vessel dilation. The study suggests that vitamins may influence minute-by-minute changes in blood vessels that lead to heart disease. Vitamins may blunt the process by releasing nitric oxide, which allows vessels to dilate.
