Researchers from the University of Bristol have discovered that a chemical compound in the brain can weaken the synaptic connections between neurons in a region of the brain important for the formation of long-term memories. The findings, published today in the Journal of Neuroscience, may also provide a potential explanation for the loss of memory associated with Alzheimer's. http://medicalxpress.com/news/2011-12-potential-explanation-mechanisms-associative-memory.html Neuroscience Tue, 13 Dec 2011 17:00:01 EST news243004672 The latest results from an expedition to Mount Everest that looked at the body's response to low oxygen levels suggest that drugs or procedures that promote the body's production of a chemical compound called nitric oxide (NO) could improve the recovery of critically ill patients in intensive care. http://medicalxpress.com/news/2011-10-everest-nitric-oxide-benefits-intensive.html Medical research Thu, 06 Oct 2011 07:19:07 EST news237104331 One of the holy grails in diabetes research is to discover molecules that stimulate beta cell growth and to find drugs that target these molecules. Now, JDRF-funded researchers in collaboration with the pharmaceutical company Hoffmann-La Roche, have done both, discovering not only a protein that regulates beta cell growth, but also a chemical compound that stimulates it. The work appears in the September 7 issue of Cell Metabolism. http://medicalxpress.com/news/2011-09-scientists-uncover-ways-pancreatic-beta.html Medical research Tue, 06 Sep 2011 14:48:20 EST news234539287 Scientists from the Monell Center report that approximately one third of patients with unexplained body malodor production test positive for the metabolic disorder trimethylaminuria (TMAU). A definitive diagnosis offers relief to these individuals, as symptoms of TMAU can hinder social and workplace interactions and cause psychological distress. But once the disease is identified, these debilitating symptoms can be ameliorated using changes in diet and other approaches. http://medicalxpress.com/news/2011-08-undiagnosed-trimethylaminuria-cases-personal-malodor.html Diseases, Conditions, Syndromes Wed, 31 Aug 2011 11:37:04 EST news234009403 An Indiana University scientist studying human bone growth has received a $2.6 million grant from the U.S. Department of Defense to study a chemical compound with potential to fight osteoporosis and accelerate broken bone healing. http://medicalxpress.com/news/2011-08-compound-bone-osteoporosis.html Medical research Wed, 17 Aug 2011 15:44:48 EST news232814657 Temporarily suppressing ovarian function with use of the hormone analogue triptorelin reduced the occurrence of early menopause induced by chemotherapy among women with breast cancer, according to a study in the July 20 issue of JAMA. http://medicalxpress.com/news/2011-07-therapy-chemotherapy-induced-early-menopause-women.html Cancer Tue, 19 Jul 2011 16:51:27 EST news230313077 Scientists at The University of Nottingham have discovered a molecular mechanism which could bring about the development of new treatments for Multiple Sclerosis (MS) -- a chronic inflammatory disease of the central nervous system. http://medicalxpress.com/news/2011-06-breakthrough-treatments-multiple-sclerosis.html Medical research Tue, 21 Jun 2011 09:27:54 EST news227867260
