Other proteins are often co-deposited with amyloid beta including serum amyloid P component. Recent evidence has suggested that SAP is elevated in Alzheimer's disease. Researchers from Keele University have shown that physiologically-significant concentrations of SAP promote the deposition of amyloid beta under conditions approaching those found in vivo. http://medicalxpress.com/news/2012-03-amyloid-beta-brain-individuals-alzheimer.html Alzheimer's disease & dementia Fri, 30 Mar 2012 12:53:49 EST news252330808 Living kidney donors are at no greater risk of heart disease than the healthy general population, finds a study published in the British Medical Journal today. http://medicalxpress.com/news/2012-03-kidney-donors-heart-disease.html Cardiology Fri, 02 Mar 2012 04:23:37 EST news249884596 The World Health Organization said Friday it will meet next week to determine whether scientists can publish research on a bird flu virus that may be easily passed among humans. http://medicalxpress.com/news/2012-02-health-experts-scientists-discuss-bird.html Diseases, Conditions, Syndromes Fri, 10 Feb 2012 13:30:02 EST news248102357 Life shrouds most choices in mystery. Some people inch toward a comfortable enough spot and stick close to that rewarding status quo. Out to dinner, they order the usual. Others consider their options systematically or randomly. But many choose to grapple with the uncertainty head on. "Explorers" order the special because they aren't sure they'll like it. It's a strategy of maximizing rewards by discovering whether as yet unexplored options might yield better returns. In a new study, Brown University researchers show that such explorers use a specific part of their brain to calculate the relative uncertainty of their choices, while non-explorers do not. http://medicalxpress.com/news/2012-02-explorers-embrace-uncertainty-choices-specific.html Neuroscience Wed, 08 Feb 2012 12:00:05 EST news247918484 (Medical Xpress) -- This week, the deficit reduction supercommittee failed to reach a consensus in creating a plan to reduce the national deficit by at least $1.2 trillion.

When these genetic disorders affect the integrity of the heart's muscle they are known as a "cardiomyopathy"; when the disorder affects the heart's "excitability", it is known as a "channelopathy". http://medicalxpress.com/news/2011-06-genetic-inherited-cardiac-conditions-patchy.html Cardiology Mon, 27 Jun 2011 03:28:24 EST news228364086 An international panel of experts from The Heart Rhythm Society and the European Heart Rhythm Association issued new guideline recommendations for all health care professionals about cardiovascular genetic testing at the Heart Rhythm Society's 32nd Annual Scientific Sessions. http://medicalxpress.com/news/2011-05-guidelines-cardiovascular-genetic.html Cardiology Fri, 06 May 2011 12:58:38 EST news223905481
