The method could radically shorten the path from the lab to their application. http://medicalxpress.com/news/2012-07-cancer-biomarkers-re-evaluated.html Cancer Thu, 19 Jul 2012 09:25:41 EST news261908719 Many people talk of problem gambling as an 'addiction' but work coming out of the University of Sydney's Gambling Treatment Clinic suggests that this may not be the case. http://medicalxpress.com/news/2012-05-gambling-addiction-university-sydney.html Addiction Mon, 14 May 2012 06:02:58 EST news256194172 Breast cancer in young women is linked to age-related biological processes, a new study shows. Because it is a biologically unique disease, it calls for tailor-made management strategies, researchers reported at the IMPAKT Breast Cancer Conference in Brussels, Belgium from 3 to 5 May. The findings, presented in the journal Annals of Oncology, could impact potential treatment methods, especially because breast cancer in young women is often aggressive and diagnosed at an advanced stage. The prognosis for young patients is not good. http://medicalxpress.com/news/2012-05-scientists-link-biological-young-breast.html Cancer Mon, 07 May 2012 06:40:53 EST news255591644 Scientists at the Gladstone Institutes have unraveled a process by which depletion of a specific protein in the brain contributes to the memory problems associated with Alzheimer's disease. These findings provide new insights into the disease's development and may lead to new therapies that could benefit the millions of people worldwide suffering from Alzheimer's and other devastating neurological disorders. http://medicalxpress.com/news/2012-04-scientists-mechanism-contribute-problems-alzheimer.html Alzheimer's disease & dementia Thu, 26 Apr 2012 12:35:50 EST news254662523 Researchers at the Hebrew University of Jerusalem and other institutions have identified two distinguishable groups of genes: those that produce very abundant biochemical products in the cell and function properly in the majority of biological processes, and a flexible subset that might have abnormal function in a disease. http://medicalxpress.com/news/2012-04-distinguishable-gene-groups-problematic.html Genetics Mon, 23 Apr 2012 11:29:30 EST news254399355 The genetic pathway that regulates the way cells align themselves relative to each other has been found to act as a "stop sign" that signals organisms when to halt cell growth, according to new research published by biologists at the Center for Regenerative and Developmental Biology in Tufts University's School of Arts and Sciences. http://medicalxpress.com/news/2012-03-pcp-genetic-pathway-cell-growth.html Medical research Thu, 15 Mar 2012 09:48:50 EST news251023721 Researchers at Boston University School of Medicine (BUSM) have, for the first time, identified an intracellular signaling enzyme that regulates the wake-sleep cycle, which could help lead to the development of more effective sleep aid medications. Subimal Datta, PhD, director and principle investigator at the Laboratory of Sleep and Cognitive Neuroscience at BUSM, led the study, which points to a specific enzyme inside neurons in the brain that trigger an important shift in consciousness from sleep to wakefulness and wakefulness to sleep. http://medicalxpress.com/news/2011-11-molecular-mechanism.html Sleep apnea Tue, 22 Nov 2011 17:24:48 EST news241205082 For people who initially survive a heart attack, a significant cause of death in the next few days is cardiac rupture -- literally, bursting of the heart wall. http://medicalxpress.com/news/2011-11-heart-rupture.html Cardiology Thu, 17 Nov 2011 15:16:59 EST news240765397 The list of aging-associated proteins known to be involved in cancer is growing longer, according to research by investigators at Vanderbilt-Ingram Cancer Center and the National Institutes of Health (NIH). http://medicalxpress.com/news/2011-10-protein-family-key-aging-cancer.html Cancer Mon, 17 Oct 2011 12:21:59 EST news238072906 A new study by researchers at NYU Langone Medical Center has shown that, for the first time, Wnt signaling, already known to control many biological processes, between hair follicles and melanocyte stem cells can dictate hair pigmentation. The study was published in the June 11, 2011 issue of the journal Cell. http://medicalxpress.com/news/2011-06-clues-hair-gray.html Medical research Tue, 14 Jun 2011 11:04:51 EST news227268282 Intense distress and fear of dying, which many people experience when suffering the symptoms of a heart attack, are not only fairly common emotional responses but are also linked to biological changes that occur during the event, according to new research published online today in the European Heart Journal [1]. These changes, in turn, are associated with other biological processes during the following weeks that can predict a worse outcome for patients. http://medicalxpress.com/news/2011-06-dying-heart-linked-inflammation.html Cardiology Thu, 02 Jun 2011 06:43:35 EST news226215781
