Their findings are published in the Dec. 22 early online issue of the Journal of Clinical Investigation. http://www.physorg.com/news149189043.html Medicine & Health Mon, 22 Dec 2008 17:24:03 EST news149189043 New research out of the University of Pittsburgh indicates that patients' perceptions of their own health and balance have an impact on how much they walk. The study was originally published in Physical Therapy (December 2008), the scientific journal of the American Physical Therapy Association (APTA). http://www.physorg.com/news148927101.html Medicine & Health Fri, 19 Dec 2008 16:38:21 EST news148927101 The American Physical Therapy Association (APTA) is urging patients with musculoskeletal pain to consider treatment by a physical therapist, in light of a new federal survey showing that more than one-third of American adults and nearly 12 percent of children use alternative medicine - with back and neck pain being the top reasons for treatment. Results of the 2007 survey of more than 32,000 Americans were released Dec. 11 by the National Institutes of Health's National Center for Complementary and Alternative Medicine. http://www.physorg.com/news148578291.html Medicine & Health Mon, 15 Dec 2008 15:44:51 EST news148578291 For breast cancer survivors, the idea of taking estrogen pills is almost a taboo. In fact, their doctors give them drugs to get rid of the hormone because it can fuel the growth of breast cancer. So these women would probably be surprised by the approach taken by breast cancer physician Matthew Ellis, M.B., Ph.D., associate professor of medicine at Washington University School of Medicine in St. Louis - he has demonstrated that estrogen therapy can help control metastatic breast cancer. http://www.physorg.com/news148227949.html Medicine & Health Thu, 11 Dec 2008 14:25:49 EST news148227949 Scientists at the University of Michigan have shown that gene therapy can be used to successfully stop the development of periodontal disease, the leading cause of tooth loss in adults. The findings will be published online Dec 11 in advance of print publication in Gene Therapy. http://www.physorg.com/news148227890.html Medicine & Health Thu, 11 Dec 2008 14:24:50 EST news148227890 The apparent success of a case in which German doctors cured a man of AIDS using a bone marrow transplant comes as no surprise to Gerhard Bauer, a UC Davis stem cell researcher. Bauer has been working for more than 10 years on a similar cure for AIDS based on replacing the devastated immune system of an HIV-infected patient with stem cells that have been engineered to resist human immunodeficiency syndrome. http://www.physorg.com/news147720965.html Medicine & Health Fri, 05 Dec 2008 17:36:05 EST news147720965 An NIH funded multi-center clinical trial found no benefit from "maintenance therapy," low-dose peginterferon used for hepatitis C patients who have not responded to an initial round of treatment. In addition, the study showed a surprising health decline in patients with liver disease over the course of four years. http://www.physorg.com/news147551365.html Medicine & Health Wed, 03 Dec 2008 18:29:25 EST news147551365 A new Mayo Clinic study found that patients with low-grade gliomas survived longest when they underwent aggressive surgeries to successfully remove the entire tumor. If safely removing the entire tumor was not possible, patients survived significantly longer when surgery was followed by radiation therapy. This study is available online as an advance publication in Neuro-Oncology. http://www.physorg.com/news147546162.html Medicine & Health Wed, 03 Dec 2008 17:02:42 EST news147546162 Patients treated with radiation prior to surgery for advanced rectal cancer have fewer instances of cancer recurrence and better overall survival rates, according to a recent Geisinger report. http://www.physorg.com/news147446266.html Medicine & Health Tue, 02 Dec 2008 13:17:46 EST news147446266 Women with early-stage breast cancer who have undergone breast augmentation may be treated successfully with a partial-breast radiation treatment called brachytherapy, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).

With the end of Daylight Saving time many Americans are affected by the increased darkness and experience what is known as the winter blues. Symptoms of the winter blues may include lethargy, lowered mood, problems sleeping, carbohydrate cravings and weight gain. http://www.physorg.com/news144676945.html Electronics Fri, 31 Oct 2008 13:02:25 EST news144676945 Approximately 250,000 people in the United States have some form of muscular dystrophy. Duchenne muscular dystrophy (DMD) is the most common type of the disease, predominantly affecting males. Boys with DMD will lose the ability to walk by their teens and typically die before the age of 30. For years, scientists have studied the use of gene therapy as a possible way to correct the muscle deterioration, but hurdles such as the need to treat all muscles in the body, including both skeletal muscle and heart muscle, have challenged researchers looking for an effective therapy until now. http://www.physorg.com/news144494576.html Medicine & Health Wed, 29 Oct 2008 10:22:56 EST news144494576 (PhysOrg.com) -- When it comes to recovering mobility after a stroke, therapists say that every step counts. Two University of Missouri researchers recently studied robotic gait-assisted therapy to see if it is the best way to make steps count for patients with neurological injuries. http://www.physorg.com/news144339398.html Medicine & Health Mon, 27 Oct 2008 15:16:38 EST news144339398 Massachusetts General Hospital (MGH) researchers have used gene therapy to restore useful vision to mice with degeneration of the light-sensing retinal rods and cones, a common cause of human blindness. Their report, appearing in the Oct. 14 Proceedings of the National Academy of Sciences, describes the effects of broadly expressing a light-sensitive protein in other neuronal cells found throughout the retina. http://www.physorg.com/news143381912.html Medicine & Health Thu, 16 Oct 2008 13:18:32 EST news143381912 Scientists have found a more effective treatment for a common childhood eye muscle coordination problem called convergence insufficiency (CI). For words on a page to appear in focus a child's eyes must turn inward, or converge. In CI, the eyes do not converge easily, and as a result, additional muscular effort must be used to make the eyes turn in. http://www.physorg.com/news143287383.html Medicine & Health Wed, 15 Oct 2008 11:03:03 EST news143287383 (PhysOrg.com) -- Research published by scientists from the University of Reading may offer an insight into ways of making safer and more specific gene therapy vectors. The research, published in the journal Nature Structural and Molecular Biology, describes the structure of the viral fusion protein gp64, which is involved in the mechanism which viruses use to invade host cells. In the past, Bacloviruses have been suggested as possible gene therapy vectors due to the way in which they enter host cells, but there has been little evidence which explain these properties up to now. http://www.physorg.com/news142610761.html Biology Tue, 07 Oct 2008 15:06:01 EST news142610761
