Acupuncture Reduces Pain, Need For Opioids After Surgery
10/18/07
Using acupuncture before and during surgery significantly reduces the level of pain and the amount of potent painkillers needed by patients after the surgery is over, according to anesthesiologists who combined data from 15 small randomized acupuncture clinical trials.
'Bionic' Nerve To Bring Damaged Limbs And Organs Back To Life
University of Manchester researchers have transformed fat tissue stem cells into nerve cells -- and now plan to develop an artificial nerve that will bring damaged limbs and organs back to life. In a study published in October's Experimental Neurology, Dr Paul Kingham and his team at the UK Centre for Tissue Regeneration isolated the stem cells from the fat tissue of adult animals and differentiated them into nerve cells to be used for repair and regeneration of injured nerves. They are now about to start a trial extracting stem cells from fat tissue of volunteer adult patients, in order to compare in the laboratory human and animal stem cells.
Gene Defects Could Be New Cause Of Male Infertility
Scientists have identified a gene crucial to the final step of the formation of a functional sperm cell. That final step -- called spermiogenesis -- entails the compaction of DNA into a tight ball within the head of the sperm so it can successfully penetrate an egg. Mice engineered to lack the crucial gene, Jhdm2a, that triggers this process did not produce many mature sperm, and those they did produce had abnormally shaped heads and immotile tails.
Bone Structure 'Vastly Different' Than Previously Believed
Researchers have discovered that the structure of human bones is vastly different than previously believed. The characteristic toughness and stiffness of bone is predominantly due to the presence of specialized sugars, not proteins. Their findings could have sweeping impacts on treatments for osteoporosis and other bone disorders. One of the scientists notes that this may strengthen the rational for using glucosamine or chondroitin.
