Bad Outcomes Related To, But Not Caused By, Misdosing Of Clotbusters I
The deaths or clinical complications in heart attack patients given potent drugs to re-open clogged arteries is more likely to be due to individual patient characteristics than to modest misdosing of the drugs, researchers from the Duke Clinical Research Institute (DCRI) have determined. Thus, they said, physicians should not be overly worried about the possibility of minor errors in dosing -- a concern that the Duke physicians said likely contributes to insufficient prescribing of the drugs to treat heart attacks. Genomic Instability And Premature Aging
Premature aging syndromes often result from mutations in nuclear proteins involved in genomic integrity. Lack of an enzyme responsible for the maturation of prelamin A, also results in progeroid phenotypes in mice and humans. In Nature Medicine Online researchers at Karolinska Institutet and the University of Hong Kong describe this enzyme's importance for the stability of DNA. March Of The Giant Penguins: Prehistoric Equatorial Penguins Reached 5
Two heretofore undiscovered penguin species -- one of which was over 5 feet tall -- reached equatorial regions tens of millions of years earlier than expected and during a period when the earth was much warmer than it is now. Purdue Creates New Low-cost System To Detect Bacteria
Researchers at Purdue University have developed a new low-cost system that analyzes scattered laser light to quickly identify bacteria for applications in medicine, food processing and homeland security at one-tenth the cost of conventional technologies. Electric Fish Conduct Electric Duets In Aquatic Courtship
Scientists have discovered that African electric fish couples not only use specific electrical signals to court but also engage in a sort of dueling "electric duet." Exposure To Environmental Toxics Accelerates Age-related Parkinson's D
Scientists at the Buck Institute for Age Research have shown that combining two environmental toxic substances accelerated age-related degeneration in neurons associated with Parkinson's disease (PD) in mice. Additionally, the study showed that pre-treating the mice with an antioxidant weakened the impact of the environmental exposures, suggesting the substances damage the neurons via oxidative stress. The toxics involved include increased neonatal iron intake and exposure to the herbicide paraquat. Plastic Surgery To Restore Facial Defects
Insurance companies may deem reconstructing severe facial deformities in children with mental disabilities as cosmetic surgery and refuse to cover them. However, craniofacial plastic surgery, to correct abnormalities of the face, skull and neck, may give these children significant psychological, social and emotional benefits that can help them attain a better quality of life, according to a report in the August issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS). Greenhouse gas carbon dioxide ramps up aspen growth
The rising level of atmospheric carbon dioxide may be fueling more than climate change. It could also be making some trees grow like crazy. That is the finding of a new study of natural stands of quaking aspen, one of North America's most important and widespread deciduous trees. Presbycusis
Fact sheet on presbycusis, the loss of hearing that gradually occurs in most individuals as they grow older. Discusses symptoms, causes, prevention, hearing aids, communication tips, and related topics. From the National Institute on Deafness and Other Communication Disorders, National Institutes of Health. New Device Could More Effectively Alleviate Menstrual Cramp Pain
While most women experience minor pain during menstruation, for others, the pain can be severe enough to interfere with everyday activities and require medication. New research reveals initial findings of safety surrounding a new device that may more effectively treat menstrual pain.
