(Medical Xpress)—Waging an immunological war against a pathogen is not the body's only way to survive an infection. Sometimes tolerance, or learning to live with an invader, can be just as important. In tolerance the body lessens or repairs the damage that the pathogen causes. http://medicalxpress.com/news/2013-04-infections.html Immunology Mon, 29 Apr 2013 07:50:01 EST news286438914 (Medical Xpress)—The University of Delaware's Prasad Dhurjati is a chemical engineer whose background includes systems engineering, biotechnology and artificial intelligence.

At that point, patients and families have a choice: tube feeding or IV nutrition supplement. Which would you choose?

Having bound to its receptors, the neuropeptide S reaches particular neurons in the brain in this way. Just four hours after the administration of the drug, the tested mice showed less anxiety. Altered neuronal activity was also measured directly in the hippocampus, an important brain structure for learning and memory. These findings confirm that neuropeptide S is a promising new drug for the treatment of patients suffering from anxiety disorders. http://medicalxpress.com/news/2012-03-nose-panic.html Neuroscience Mon, 05 Mar 2012 08:54:28 EST news250159947 (Medical Xpress) -- The debate over the bacteria Helicobacter pylori continues as a new study published in Clinical Infectious Diseases shows that people carrying H. pylori have a reduced risk of diarrhea from other bacterial causes. http://medicalxpress.com/news/2011-12-pros-cons-helicobacter-pylori.html Medical research Tue, 27 Dec 2011 17:20:04 EST news244226659 Teaming fresh broccoli with a spicy food that contains the enzyme myrosinase significantly enhances each food's individual cancer-fighting power and ensures that absorption takes place in the upper part of the digestive system where you'll get the maximum health benefit, suggests a new University of Illinois study. http://medicalxpress.com/news/2011-09-evidence-spicing-broccoli-boosts-cancer-fighting.html Health Tue, 13 Sep 2011 08:33:02 EST news235121560 (Medical Xpress) -- Computer games which help young people with cystic fibrosis cope better with treatment, and improve monitoring of their condition, are being developed by the University of Derby. http://medicalxpress.com/news/2011-08-games-cystic-fibrosis-kids.html Diseases, Conditions, Syndromes Tue, 16 Aug 2011 09:58:09 EST news232707470 Constipation is definitely not a glamorous topic. In reality, it affects nearly 30 million Americans and costs more than $1 billion annually to evaluate and treat. While not often life threatening, the pain, bloating, discomfort, and straining associated with constipation lead sufferers to focus on one thing - relief. Mayo Clinic researchers recently had success in the clinical trial of a new medication shown to provide relief from constipation in a way that capitalizes on the body's natural processes. http://medicalxpress.com/news/2011-05-treatment-constipation.html Diseases, Conditions, Syndromes Tue, 10 May 2011 09:58:39 EST news224240252
