Improving clinical use of stem cells to repair heart damage (July 16, 2010) -- Researchers have presented a new approach to treating heart attack and cardiomyopathy using stem cells. The team has discovered a way to identify heart stem cells so as to purify them for transplant. ... > full story
New method of tissue banking makes gene analysis more practical for lung cancer (July 16, 2010) -- Analyzing the genes expressed by cancer cells allows for a better understanding of that patient's specific disease and in turn, a more personalized approach to treatment. But obtaining the RNA from a tumor in the lungs in order to conduct the genetic analysis is a challenging prospect. Currently, lung cancer researchers are limited to using RNA extracted from early-stage tumors removed during surgery. ... > full story
Studies explore effects of war on former child soldiers (July 16, 2010) -- Two studies found that how child soldiers adapt upon returning home depends on the communities they return to. The first study, of 150 former child soldiers in Sierra Leone, found that children who lived in communities where they felt accepted were less depressed and more confident. The second study, of 330 former Ugandan child soldiers, found that the most resilient children were those who returned to less violent communities and better family socioeconomic situations. ... > full story
New discovery brings hope to treatment of incurable blood cancer (July 16, 2010) -- Multiple myeloma is one of the most common blood cancers, and at present considered to be incurable. Researchers now present a conceptually new model for the development and progression of multiple myeloma. ... > full story
Less salt for everybody (July 16, 2010) -- Restricting the amount of sodium chloride in food can lower the risk of cardiovascular morbidities, according to a new study. ... > full story
Apathy and depression predict progression from mild cognitive impairment (July 16, 2010) -- A new study found that apathy and depression significantly predict an individual's progression from mild cognitive impairment (MCI), a disorder of the brain that affects nerve cells involved in thinking abilities, to dementia, including Alzheimer's disease and Lewy body dementia. ... > full story
Genetic ancestry data improve diagnosis in asthma and lung disease (July 16, 2010) -- Researchers have found that patients' precise genetic background told far more about their potential lung function -- and therefore any damage that has occurred -- than the self-identified racial profile commonly used in such tests. The results point to a more precise method of assessing patients' lung function, as well as the potential impact of using precise genetic benchmarks for assessing health overall. ... > full story
Arthroscopic treatment of common hip problem allows athletes to return to play, study finds (July 16, 2010) -- Patients who undergo arthroscopic surgery for a mechanical disorder of the hip have a good chance of being able to return to their sport at a high level of competition, according to a new study. ... > full story
New radiation mechanism may ward off cancer, oil spills and terrorism (July 16, 2010) -- Radiation similar to that used to treat cancer may someday help clean up environmental disasters such as the Gulf oil spill and detect explosive powder hidden underneath clothing. ... > full story
