A stomach bacterium believed to cause health problems such as gastritis, ulcers, and gastric cancer may play a dual role by balancing the stomach's ecosystem and controlling body weight and glucose tolerance, according to immunologists at the Virginia Bioinformatics Institute of Virginia Tech. http://medicalxpress.com/news/2013-02-villain-stomach-bug-sweet-side.html Medical research Fri, 08 Feb 2013 17:19:19 EST news279566311 A new study by NYU School of Medicine researchers reveals that an especially virulent strain of the gut bacterium Helicobacter pylori (H. pylori) isn't implicated in the overall death rate of the U.S. population, and may even protect against stroke and some cancers. The findings, based a nationwide health survey of nearly 10,000 individuals over a period of some 12 years, are published online, January 9, in the journal Gut. http://medicalxpress.com/news/2013-01-bacterium.html Diseases, Conditions, Syndromes Wed, 09 Jan 2013 00:00:02 EST news276883496 (Medical Xpress)—Scientists at the University of Liverpool have identified the origin of an epidemic strain of Clostridium difficile (027) and its mode of spread using tagging genetic signatures in the DNA of bacteria, some of them associated with its increased virulence. http://medicalxpress.com/news/2012-12-scientists-bacterial-strain-severe-clostridium.html Genetics Fri, 21 Dec 2012 07:00:04 EST news275294448 A four-year-old boy has died of bird flu in Indonesia, the health ministry said Tuesday, the 10th fatal case in the country this year. http://medicalxpress.com/news/2012-12-four-year-old-dies-bird-flu-indonesia.html Diseases, Conditions, Syndromes Tue, 18 Dec 2012 05:00:01 EST news275028459 The Caenorhabditis elegans, a small worm called a nematode, scurrying across a Petri dish has helped lead to discoveries about community-associated MRSA (methicillin-resistant Staphylococcus aureus). http://medicalxpress.com/news/2012-12-combating-mrsa-community-associated-strain.html Diseases, Conditions, Syndromes Tue, 04 Dec 2012 17:52:19 EST news273865867 While it may be that some Americans doubt we're related to chimps and other primates, viruses recognize the similarities in our cells. http://medicalxpress.com/news/2012-10-viruses-species-rapidly.html HIV & AIDS Mon, 22 Oct 2012 19:20:01 EST news270148208 Cambodian villagers armed with a little medical know-how—and their mobile telephones—are the nation's new foot soldiers in the fight against drug-resistant malaria. http://medicalxpress.com/news/2012-09-cambodians-malaria-button.html Diseases, Conditions, Syndromes Mon, 17 Sep 2012 05:00:02 EST news267075717 Dozens of pet birds smuggled from southern China into Taiwan tested positive for the deadly H5N1 avian flu virus and were destroyed, Taiwanese authorities said Tuesday. http://medicalxpress.com/news/2012-07-taiwan-h5n1-virus-birds-smuggled.html Diseases, Conditions, Syndromes Tue, 17 Jul 2012 06:41:23 EST news261726078 (AP) — A deadly form of a common childhood illness has been linked to the mysterious child deaths in Cambodia that sparked alarm after a cause could not immediately be determined, health officials said Monday. http://medicalxpress.com/news/2012-07-cambodia-deaths-tied-common-child.html Diseases, Conditions, Syndromes Mon, 09 Jul 2012 04:16:27 EST news261026179 A top Taiwan agriculture official stepped down Sunday amid allegations he covered up bird flu outbreaks, a day after authorities said they had culled thousands of chickens. http://medicalxpress.com/news/2012-03-taiwan-bird-flu-cover-up.html Other Sun, 04 Mar 2012 05:30:38 EST news250061431 Taiwan's authorities said Saturday they had culled nearly 58,000 chickens following the latest outbreak of the less virulent strain of bird flu. http://medicalxpress.com/news/2012-03-taiwan-chicken-cull-bird-flu.html Diseases, Conditions, Syndromes Sat, 03 Mar 2012 12:59:50 EST news250001985 While some scientists report engineering a super virulent strain of the H5N1 influenza virus, which could potentially wipe out a significant percentage of the human population, another group of researchers from the United Kingdom now reports a discovery that may one day help mitigate the deadly effects of all flu strains. This report, appearing in the March 2012 print issue of the Journal of Leukocyte Biology, describes findings that may help prevent deaths from severe flu outbreaks, especially from seemingly healthy young people. Specifically, the researchers found that immune cells called, "natural killer T cells," may reduce the overwhelming numbers of another type of immune cell, called "inflammatory monocytes," which when present in large numbers, lead to lung injury at the end stage of severe flu infection. http://medicalxpress.com/news/2012-02-lung-injury-severe-flu.html Diseases, Conditions, Syndromes Wed, 29 Feb 2012 10:52:43 EST news249735151 New guidelines from the American Academy of Neurology will help physicians better choose seizure drugs for people on HIV/AIDS medication, avoiding deadly drug interactions and preventing critical anti-HIV drugs from becoming less effective, possibly leading to a more virulent strain of the disease. http://medicalxpress.com/news/2012-01-guidelines-stress-caution-combining-anti-epileptic.html Neuroscience Wed, 04 Jan 2012 16:02:27 EST news244915279 Guided by insights into how mice recover after H1N1 flu, researchers at Harvard Medical School and Brigham and Women's Hospital, together with researchers at A*STAR of Singapore, have cloned three distinct stem cells from the human airways and demonstrated that one of these cells can form into the lung's alveoli air sac tissue.
