...natural estrogen or that which is introduced during therapy - is protective. Now, two new, related studies in the Aug. 29 online edition of Neurology lend more support to that theory: these studies show that in women under 50, estrogen acts as a defense against later cognitive impairment, dementia and Parkinson's disease...
Rocca and his group conducted a second, more comprehensive study with the same women. With better funding this time, researchers were able to examine patients in person in order to study the impact of ovary removal on movement disorders, such as Parkinson's disease. Again, the researchers found a powerful effect: when ovaries were removed at a relatively young age, the risk of Parkinson's disease increased. For women who had both ovaries removed before age 48, there was an exact doubling of risk compared with women with intact ovaries...
...stem cells using a delicate cloning technique called somatic cell nuclear transfer (SCNT). If Hwang had actually done what he had claimed, he would certainly have brought stem-cell-based therapies closer to reality, by making it possible to develop patient-specific cells to treat diseases from diabetes to Parkinson's. Two years after his announcement, however, allegations of fraud led to an investigation by an independent committee of scientists, which failed to verify his findings, and Hwang and his feat were discredited; last year he and his principal researchers were fired from their posts at Seoul National University...
...that parthenogenetic stem cells have been discovered, will we finally begin to see the kind of individualized treatments - for diabetes, Parkinson's, Alzheimer's and spinal cord injuries - that science has promised? Probably not. Although parthenogenesis is easier to achieve than nuclear transfer - about 20% of the time, eggs can be stimulated to divide on their own, compared to a 3%-5% development rate for nuclear transfer embryos - parthenogenesis still requires a steady supply of good quality human eggs. These are notoriously difficult to obtain, so the technique won't likely revolutionize medicine yet. But, suggests Daley, it could...
...like device in the chest. Low doses of current can then be applied as needed to calm the turmoil in the regions of the brain that cause OCD. The procedure sounds extreme--and it is--but it's already been used in about 35,000 people worldwide to treat Parkinson's disease, and FDA approval to use DBS for OCD as well is pending. "Many of our OCD patients are able to re-engage in life rather than being stuck at home," says neurosurgeon Ali Rezai of the Cleveland Clinic, who performs DBS surgery for Parkinson's and has researched...
