Oil dispersant used in Gulf Oil Spill causes lung and gill injuries to humans and aquatic animals, also identifies protective enzyme New research suggests that Corexit EC9500A, an oil-dispersant agent, contributes to damage to epithelial cells within the lungs of humans and gills of marine creatures.
Phone counseling reduces pain, disability after back surgery Having a short series of phone conversations with trained counselors can substantially boost recovery and reduce pain in patients after spinal surgery.The phone calls, designed to enrich standard pre- and postoperative care by reinforcing the value of sticking with physical therapy and back-strengthening exercise regimens, are a relatively inexpensive and simple intervention that can maximize surgical outcomes.
Team succeeds in doubling life span of mice suffering from premature aging An increase in the capacity to produce nucleotides, the 'building blocks' of DNA, reduces genome fragility and counteracts premature aging in mutant mice for the ATR protein. The experiments may explain the beneficial effects of folic acid, a precursor of nucleotides, which are clinically used to alleviate the degenerative symptoms associated with aging.
Beige' fat-burning cells in humans identified A research team has isolated energy-burning 'beige' fat from adult humans, which is known to be able to convert unhealthy white fat into healthy brown fat.Cigarette smoke makes superbugs more aggressive Methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic-resistant superbug, can cause life-threatening skin, bloodstream and surgical site infections or pneumonia. Researchers now report that cigarette smoke may make matters worse. The study shows that MRSA bacteria exposed to cigarette smoke become even more resistant to killing by the immune system
