(PhysOrg.com) -- When foreign invaders trip the immune system`s alarm, antibodies need to be specially sculpted to attack them head on. New research now shows that gene segments called enhancers control the reshuffling of antibody genes that makes such a precise and coordinated attack possible. http://www.physorg.com/news177931573.html Medicine & Health - Research Fri, 20 Nov 2009 09:38:53 EST news177931573 (PhysOrg.com) -- UCSF scientists studying nerve cells in fruit flies have uncovered a new function for a gene whose human equivalent may play a critical role in schizophrenia. http://www.physorg.com/news177861724.html Medicine & Health - Research Thu, 19 Nov 2009 14:03:08 EST news177861724 A protein found in the saliva of ticks helps protect mice from developing Lyme disease, Yale researchers have discovered.

Trade-offs between heath care expenditures, lifestyle choices and life expectancy have been suggested but seldom clearly demonstrated. The U.S. spends on average more than $45,000 per year on health care for every 80 year old, while the Europeans spend $12,000 for the same age group. U.S. octogenarians have a 20 percent less chance of dying than Europeans in the next year. But, more than 30 percent of the U.S. population is obese, compared to less than 10 percent of Europe's population. http://www.physorg.com/news176731282.html Medicine & Health - Research Fri, 06 Nov 2009 12:02:19 EST news176731282 A strategy that combines gene therapy with blood stem cell therapy may be a useful tool for treating a fatal brain disease, French researchers have found.
