The finding could pave the way for development of therapeutic interventions in this debilitating disease. The study appears online in the Oct. 24 issue of Science Translational Medicine. http://medicalxpress.com/news/2012-10-mechanism-uncovered-lupus.html Diseases, Conditions, Syndromes Thu, 25 Oct 2012 12:50:01 EST news270382493 Evolution has not only controlled human development over millions of years, it also has an impact on modern man. This is one of the conclusions of a study of Argentinian villagers in the Andes, where the water contains high levels of arsenic. A gene variant that produces efficient and less toxic metabolism of arsenic in the body was much more common among the villagers than among other indigenous groups in South or Central America. The study was a collaborative effort by Karin Broberg from Lund University and Carina Schlebusch and Mattias Jakobsson from Uppsala University in Sweden. http://medicalxpress.com/news/2012-10-genetic-arsenic.html Health Tue, 16 Oct 2012 12:59:12 EST news269610955 Melanoma is on the rise nationally, and transplant recipients and lymphoma patients are far likelier than the average person to get that form of skin cancer and to die from it, a Mayo Clinic review has found. That is because their immune systems tend to be significantly depressed, making early detection of melanoma even more important, says co-author Jerry Brewer, M.D., a Mayo dermatologist. The findings are published in the October issue of Mayo Clinic Proceedings. http://medicalxpress.com/news/2012-10-melanoma-likelier-transplant-lymphoma-patients.html Cancer Wed, 03 Oct 2012 13:18:36 EST news268489082 About half of all people with cancer receive a course of radiotherapy, a form of treatment in which X-rays are used to shrink or destroy the tumour. With the benefit of advanced systems, it is now possible to aim radiation beams at tumours more effectively than ever before, allowing increasing doses of radiotherapy with increased cancer cure rates, and also reducing side effects. http://medicalxpress.com/news/2012-10-methods-radiotherapy-tissue.html Cancer Mon, 01 Oct 2012 08:27:05 EST news268298815 Obese adults with excess visceral fat (fat located inside the abdominal cavity, around the body's internal organs) and biomarkers of insulin resistance had an associated increased risk for the development of type 2 diabetes mellitus, while obese individuals with higher amounts of total body fat and subcutaneous fat (underneath the skin) did not have this increased risk, according to a study in the September 19 issue of JAMA, and theme issue on obesity. http://medicalxpress.com/news/2012-09-obese-adults-excess-abdominal-fat.html Diabetes Tue, 18 Sep 2012 11:04:00 EST news267185033 Researchers at the Hebrew University of Jerusalem have discovered that a neuronal pathway—part of the autonomic nervous system—reaches the bones and participates in the control of bone development. http://medicalxpress.com/news/2012-09-neural-brain-to-bone-pathway-skeletal.html Medical research Mon, 03 Sep 2012 10:27:26 EST news265886837 New research from the laboratory of Dr. Andrea Cooper at the Trudeau Institute, just published in the European Journal of Immunology, holds promise for the improved prevention and treatment of bacterial infections and the life-threatening complications of chronic inflammation that can result from them.

Now Dr. Sandrine Sander and Professor Klaus Rajewsky of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch have identified a key element that transforms the immune cells into malignant lymphoma cells. They developed a mouse model that closely resembles Burkitt lymphoma in humans and that may help to test new treatment strategies (Cancer Cell). http://medicalxpress.com/news/2012-08-key-element-pathogenesis-burkitt-lymphoma.html Cancer Mon, 13 Aug 2012 14:17:51 EST news264086261 Brazilian researchers say they have successfully tested a vaccine against schistosomiasis, a disease caused by parasitic worms that afflicts more than 200 million people worldwide. http://medicalxpress.com/news/2012-06-brazil-successful-parasite-vaccine.html Medications Wed, 13 Jun 2012 04:30:05 EST news258780590 A pregnant woman's blood stream contains not only her own cells, but a small number of her child's, as well, and some of them remain in her internal organs long after the baby is born. Understanding the origin and identity of these cells is vital to understanding their potential effects on a mother's long-term health. For example, fetal cells have been found at tumor sites in mothers, but it is unknown whether the cells are helping to destroy the tumor or to speed its growth. http://medicalxpress.com/news/2012-06-fetal-cells-migrate-maternal-pregnancy.html Medical research Wed, 06 Jun 2012 16:00:41 EST news258217179 Just a handful of cells in the embryo are all that's needed to form the outer layer of pumping heart muscle in an adult zebrafish. http://medicalxpress.com/news/2012-04-cell-clones-heart-muscle.html Medical research Wed, 25 Apr 2012 13:00:14 EST news254577455 Most medical imaging equipment is not designed with overweight and obese patients in mind.

Without it, humans would be closer to invertebrates (think mollusks) in design, where blood simply washes through an open system to nourish internal organs. But vertebrates evolved closed circulation systems designed to more effectively carry blood to organs and tissues. http://medicalxpress.com/news/2012-02-scientists-evolutionary-secret-blood-vessels.html Medical research Tue, 21 Feb 2012 11:32:21 EST news249046279 A nine-year-old girl is making what doctors described as a remarkable recovery Sunday, days after surgeons transplanted six of her organs in a groundbreaking medical procedure. http://medicalxpress.com/news/2012-02-girl-six-organ-transplant.html Other Sun, 05 Feb 2012 14:51:49 EST news247675832 Doctors in Brazil said Thursday they have decided for now not to attempt to surgically separate a set of conjoined twins who have two heads but share one body and various vital organs. http://medicalxpress.com/news/2011-12-rare-two-headed-baby-born-brazil.html Other Thu, 22 Dec 2011 14:32:43 EST news243786753 (AP) -- Conjoined twin girls who were separated in a 20-hour operation were in critical condition on Friday and one was in danger of dying, according to the director of the Chilean hospital where they are being treated. http://medicalxpress.com/news/2011-12-chilean-twins-delicate-condition-post-surgery.html Other Fri, 16 Dec 2011 10:30:34 EST news243253820 Hi-tech medical scanners could be used to probe causes of death, reducing the need for invasive autopsies that can upset bereaved families, a study published in The Lancet on Tuesday says. http://medicalxpress.com/news/2011-11-scanners-autopsies-.html Medical research Tue, 22 Nov 2011 05:00:01 EST news241158244 The first drug to treat a rare disorder that causes red blood cells to build up inside bone marrow was cleared Wednesday by the Food and Drug Administration http://medicalxpress.com/news/2011-11-fda-drug-bone-marrow-disorder.html Medications Wed, 16 Nov 2011 12:59:10 EST news240670722 A University of Michigan Health System-led team of researchers has found a biomarker they believe can help rapidly identify one of the most serious complications in patients with leukemia, lymphoma and other blood disorders who have received a transplant of new, blood-forming cells. http://medicalxpress.com/news/2011-10-biomarker-graft-versus-host-disease-cancer-patients-bone.html Medical research Fri, 21 Oct 2011 10:06:15 EST news238410340 A drug used to treat cancer may also be effective in diseases that cause scarring of the internal organs or skin, such as pulmonary fibrosis or scleroderma. http://medicalxpress.com/news/2011-09-cancer-drug-scleroderma.html Medications Thu, 22 Sep 2011 17:02:40 EST news235929746 (Medical Xpress) -- Computer games which help young people with cystic fibrosis cope better with treatment, and improve monitoring of their condition, are being developed by the University of Derby. http://medicalxpress.com/news/2011-08-games-cystic-fibrosis-kids.html Diseases, Conditions, Syndromes Tue, 16 Aug 2011 09:58:09 EST news232707470 It's not fair, but it's true.
