University of Alabama researchers said they used transparent roundworms (C.elegans) to help them identify key "molecular switches" that control the transport of a molecule called gamma-aminobutyric acid, or GABA, that, if manipulated within our cells, might pre-vent the onset of seizures. "It is our hope that this work serves to accelerate the path toward the identification of genetic factors that cause a susceptibility to epilepsy," said Associate Professor Guy Caldwell, co-author of the study, "Simultaneously, this work has the potential to uncover new avenues toward therapeutic development to con-trol or prevent seizures in the future." The research is detailed in the journal Genetics. A new target found for lymphoma therapy BOSTON - U.S. cancer researchers say they've found a link between a common mutation that can lead to cancer and a distant gene regulator that enhances its activity. The Children's Hospital Boston scientists say their discovery could lead to drugs targeting B-cell lymphomas, including Burkitt's lymphoma, an aggressive cancer in children, as well as multiple myelomas and other blood-related cancers.Lymphomas often originate in B cells, the scientists said -- the same cells that produce antibodies to help fight infections. B cells can become cancerous if a gene known as c-myc leaps to another section of DNA -- the IgH region, responsible for building antibodies -- fuses with it, and somehow becomes over-activated. The researchers said scien-tists have wondered for years how that oncogenic activation occurs, in particular what component in the IgH region act-ivates c-myc. The new study not only identifies the regu-latory component, but marks the first time researchers are able to understand how that movement of genes, or "chrom-osomal translocation," can hijack a B cell's operation badly enough to lead to cancer. "IgH-to-myc translocation is the classic example of activation of an oncogene in cancer," says Frederick Alt, senior author of the study. "But nobody really understood how it works." The complex research is reported in the journal Nature. ---------------------------SUPER SIZE SHAMMIEMade In Germany, Don't Be Fooled By Others...

The researchers at Boston University say if confirmed, their findings, which appear in The Journal of the American Medical Association, could prove important in the hunt for effective prevention and treatment of Alzheimer's, WebMD reported Tuesday. Leptin, which is produced by fat cells, is considered critical for regulating hunger and weight. The body of evidence is growing that it also plays a role in brain development and memory. Research shows leptin reduces concentrations of B-amyloid, the major component of the deposits, or plaques, that occur in the brains of people with Alzheimer's. The latest study of 785 elderly people found that after 12 years of follow-up, those with the lowest leptin levels were roughly four times more likely than those with the highest levels to develop Alzheimer's disease. "Our study raises a strong possibility that leptin may actually have a role in the various pathological processes that result in clinical Alzheimer's disease," Dr. Sudha Seshadri, a senior researcher at Boston University School of Medicine, told WebMD. New nanoparticle might find, treat cancer HOUSTON - U.S. scientists say they've created a nanoparticle that might be able to allow both cancer diagnosis and treat-ment during one hospital visit. Rice University and Baylor College of Medicine researchers said their single nanopart-icle can be tracked in real time with magnetic resonance imaging as it homes in on cancer cells, tags them with a fluorescent dye and then kills them with heat. "Some of the most essential questions in nanomedicine today are about biodistribution -- where particles go inside the body and how they get there," said study co-author Professor Naomi Halas. "Non-invasive tests for biodistribution will be en-ormously useful on the path to FDA approval, and this tech-nique -- adding MRI functionality to the particle you're testing and using for therapy -- is a very promising way of doing this." The new research that included graduate student, Rizia Bardhan and Baylor Assistant Professor Amit Joshi appears online in the journal Advanced Functional Materials. ---------------------------MINI DISINFECTING UV SCANNER...

Sci-entists at Thomas Jefferson University in Philadelphia, led by Professor Matthias Schnell, director of the Jefferson Vaccine Center, say they have determined a rabies virus-based vaccine administered to monkeys protected them against the simian equivalent of the human immunodeficiency virus.The researchers previously showed a rabies-based vaccine expressing HIV and simian immunodeficiency virus antigens was protective against a chimeric HIV-SIV in monkeys. In their study, the researchers said they used highly attenuated rabies virus vaccine vectors to protect against a challenge with highly pathogenic SIV. That type of SIV causes a more similar disease in monkeys compared with human infection with HIV-1. In addition, it is difficult to protect monkeys against an AIDS-like disease after challenge with SIVmac251."Although we can't yet block the infection, we showed that we can protect against disease," said Schnell. "We also saw significant antibody activity against the virus, which is promising. In addition, this is a very simple approach that only took two immunizations." The data were reported in the journal Vaccine. Lab finds 89 wrong results in cancer tests QUEBEC CITY, Quebec - Of nearly 3,000 breast cancer test re-sults for Quebec women, a U.S. lab found 89 of them were incorrect, the provincial health minister said Wednesday.At a news conference, Minister of Health Yves Bolduc said 39 of the women incorrectly diagnosed required a change in their treatments, the Globe and Mail reported. Of those 39, five have since died, Bolduc said. He said the families of the dead women will be informed of the findings. Bolduc said regardless of treatment, 25 percent of women diagnosed with breast cancer die each year. The province paid $800,000 to Pheno-Path Laboratories in Seattle to re-test 2,856 samples after provincial pathologists raised concerns of discrepan-cies in the laboratory tests conducted on breast cancer patients. There is a move afoot by former cancer patients in the province to file a class-action suit over alleged im-proper treatment, the newspaper said. --------------- Health Tip Video of the Week --------------- The Diabetic´s Daily Shots Rating: 3.19 Your first thought about diabetes may be of an insulin shot, followed by a slight cringe.
