Fruit Fly Research Set To Revolutionize Study Of Birth Defects
A Queen's University study of fruit flies that may revolutionize the way birth defects are studied has identified the genes affected by a widely-prescribed drug known to cause birth defects. Methotrexate (MTX), a popular cancer-fighting drug also used to treat psoriasis, ectopic pregnancies, rheumatoid arthritis, and lupus, lasts a long time in the body and causes birth defects in children from women who have it in their systems. The study of the drug's effect on fruit flies has allowed Queen's researchers including graduate student Joslynn Affleck to identify the genes on which the drug acts. For dual-income husbands and wives, it's still a man's world
New research demonstrates that hard-working women in dual-earner couples are at a distinct disadvantage to their male peers. These women are expected to do more housework and caregiving, making them much more likely to quit their jobs. Nuke Tech in the Surf Pipeline
A foam substitute found in nuclear bombs makes superior sticks. By Heather Bourbeau from Wired magazine. New Therapeutic Options For Newly Diagnosed Multiple Myeloma Patients
Mayo Clinic researchers have presented results of a phase II trial of myeloma induction therapy -- a first step therapy designed to reduce cancer cells numbers -- with cyclophosphamide, bortezomib, and dexamethasone (Cybor-D) showing an improved response over the traditional lenalidomide-dexamethasone (L-Dex) therapy. Ventricular Regulation May Be Key To Preventing Heart Failure
A four-week study conducted on animals revealed that regulating ventricular rates and heart structure in models with irregular heart rhythms can inhibit chronic heart failure (CHF). NIMH Study To Guide Treatment Choices For Schizophrenia
A large study for the first time provides detailed information comparing the effectiveness and side effects of five medications -- both new and older medications -- that are currently used to treat people with schizophrenia. Overall, the medications were comparably effective but were associated with high rates of discontinuation due to intolerable side effects or failure to adequately control symptoms. Surprisingly, the older, less expensive medication generally performed as well as the newer medications. Molecule Could Lead To Diabetes And Obesity Pill
Researchers have discovered a small molecule that has been shown to control diabetes in mice and may pave the way to the development of easier treatment for adult-onset diabetes. The fact that the molecule also lowered appetite and promoted weight loss in mice holds out the promise it may fuel more exploration of orally available insulin sensitizing drugs that can be used to control diabetes and obesity, the scientists report. Simple Diagnostic Test Detects Genetic Signs Of Lung Cancer In A Patie
DNA coughed up along with phlegm could point to lung cancer, say researchers at the University of Maryland School of Medicine who are developing an inexpensive and non-invasive gene probe to help diagnose early stage lung cancer in current and former smokers. [Ironic] An Italian pensioner committed suicide after his wife fell in
Recalling the end of Romeo and Juliet, the 70-year-old man, Ettore, who had sat by his wife's bedside for four months after she slipped into a coma following a heart attack, finally gave up hope and gassed himself in the garage of his family home.Less than a day later, his wife, Rossana, woke up in her hospital bed in Padua and immediately asked for him. Computational feat speeds finding of genes to milliseconds instead of
Like a magician who says, "Pick a card, any card," computer scientist Debashis Sahoo seemed to be offering some kind of trick when he asked researchers to pick any two genes already known to be involved in stem cell development. Finding such genes can take years and hundreds of thousands of dollars, but Sahoo was promising the skeptical stem cell scientists that, in a fraction of a second and for practically zero cost, he could find new genes involved in the same developmental pathway as the two genes provided. Sahoo went on to show that this amazing feat could actually be performed.
