UCLA scientists have shown that temporarily blocking a protein critical to immune response actually helps the body clear itself of chronic infection. Published in the April 12 edition of Science, the finding suggests new approaches to treating persistent viral infections like HIV and hepatitis C. http://medicalxpress.com/news/2013-04-potential-therapy-hiv-blocking-key.html HIV & AIDS Thu, 11 Apr 2013 15:39:07 EST news284913540 By charting the differing fates of individual T cells, researchers have shown that previously unpredictable aspects of the adaptive immune response can be effectively modeled. The crucial question: What determines which of the immune system's millions of cells will mobilize to fight an acute infection and which will be held back to survive long-term, forming the basis of the immunological memory? The scientists' findings, published in the journal Science, could have implications for improved immunotherapy and vaccination strategies. http://medicalxpress.com/news/2013-03-insights-immune-fates-individual-cells.html Medical research Wed, 20 Mar 2013 13:37:02 EST news283005409 Administration of the drug eritoran to patients with severe sepsis and septic shock failed to demonstrate a significant effect on reducing all-cause 28-day mortality or 1-year mortality, compared with placebo, according to a study in the March 20 issue of JAMA. http://medicalxpress.com/news/2013-03-drug-significantly-death-patients-severe.html Diseases, Conditions, Syndromes Tue, 19 Mar 2013 16:00:13 EST news282927324 (HealthDay)—Of all the diseases people worry about getting, viral hepatitis is usually way down on the list. Most often it's thought of as a disease that affects only drug addicts or the sexually promiscuous. Though those groups are at higher risk, almost anyone can contract hepatitis. http://medicalxpress.com/news/2012-12-hepatitis-hidden-hazard.html Diseases, Conditions, Syndromes Fri, 21 Dec 2012 13:06:46 EST news275317598 (Medical Xpress)—More than a million people die each year of malaria caused by different strains of the Plasmodium parasite transmitted by the Anopheles mosquito. The medical world has yet to find an effective vaccine against the deadly parasite, which mainly affects pregnant women and children under the age of five. By figuring out how the most dangerous strain evades the watchful eye of the immune system, researchers from the Hebrew University of Jerusalem have now paved the way for the development of new approaches to cure this acute infection. http://medicalxpress.com/news/2012-12-deadly-malaria-parasite-evades-immune.html Medical research Mon, 03 Dec 2012 08:58:30 EST news273747380 When you get an acute infection, such as influenza, the body generally responds with a coordinated response of immune-cell proliferation and attack that rapidly clears the pathogen. Then, their mission done, the immune system stands down, leaving a population of sentinel memory cells to rapidly redeploy the immune system in the event of reinfection. http://medicalxpress.com/news/2012-11-molecular-root-exhausted-cells-chronic.html Medical research Thu, 29 Nov 2012 14:54:20 EST news273423242 Research from the Rothman Institute at Jefferson has shown aspirin to be just as effective as warfarin in preventing clots, specifically pulmonary emboli, life-threatening blood clots that can develop in the arteries of the lungs following joint replacement surgery. Their research was recognized as one of the best poster presentations at the recent American Association of Hip and Knee Surgeons meeting in Dallas. http://medicalxpress.com/news/2012-11-aspirin-effective-clots-joint-surgery.html Cardiology Thu, 08 Nov 2012 10:04:01 EST news271591419 The generation of new memories in the human immune system doesn't come at the cost of old ones, according to a study published on March 5th in the Journal of Experimental Medicine. http://medicalxpress.com/news/2012-03-cell-memories.html Immunology Mon, 05 Mar 2012 12:00:05 EST news250165708 After recovering from the flu or another acute infection, your immune system is ready to react quickly if you run into the same virus again. White blood cells called memory T cells develop during the infection and help the immune system remember the virus and attack it if it comes back. http://medicalxpress.com/news/2011-08-fragile-immune-memories-chronic-infections.html Medical research Thu, 18 Aug 2011 14:47:13 EST news232897616 Researchers from Hasbro Children's Hospital in Providence, R.I., report that medical management may be preferred over surgery for children with orbital cellulitis, an acute infection of the tissues surrounding the eye. They have determined the criteria for surgical intervention should be dependent upon the size of a subperiosteal abscess (SPA). The research is published in the journal Ophthalmic Plastic & Reconstructive Surgery and is now available online in advance of print. http://medicalxpress.com/news/2011-06-children-eye-infections-surgery.html Diseases, Conditions, Syndromes Wed, 08 Jun 2011 10:04:53 EST news226746275
