Researchers at Lund University have succeeded in preventing very early symptoms of Huntington's disease, depression and anxiety, by deactivating the mutated huntingtin protein in the brains of mice. http://medicalxpress.com/news/2013-05-breakthrough-huntington-disease.html Neuroscience Thu, 23 May 2013 11:32:40 EST news288527467 A single antibody could be the key to treating multiple myeloma, or cancer of the blood, currently without cure or long-term treatment. http://medicalxpress.com/news/2013-05-treatment-blood-cancer.html Cancer Mon, 06 May 2013 08:57:34 EST news287049445 The heart responds to the increased stress caused by chronically raised blood pressure, for example, by thickening its wall muscle. In the late stage of this condition, a risk of heart failure arises. Scientists from the Max Planck Institute for Heart and Lung Research have now succeeded in identifying a key molecule in the molecular signalling cascade responsible for this growth. Based on this discovery, they managed to achieve a significant reduction in cardiac wall thickening in animal experiments. In addition, they managed to partly reduce existing thickening of the cardiac wall. http://medicalxpress.com/news/2013-03-pathological-thickening-cardiac-wall-halted.html Cardiology Tue, 26 Mar 2013 10:26:00 EST news283512344 Wageningen University in the Netherlands has developed a prototype vaccine against chikungunya in a joint effort with the Erasmus Medical Centre and TI Pharma. This prototype may hopefully lead to the first working vaccine against chikungunya, a geographically strongly expanding viral disease. http://medicalxpress.com/news/2013-03-prototype-chikungunya-vaccine.html Diseases, Conditions, Syndromes Thu, 21 Mar 2013 08:22:24 EST news283072916 A 98-year-old researcher argues that, contrary to decades of clinical assumptions and advice to patients, dietary cholesterol is good for your heart – unless that cholesterol is unnaturally oxidized (by frying foods in reused oil, eating lots of polyunsaturated fats, or smoking). http://medicalxpress.com/news/2013-02-lipid-dietary-heart-disease.html Cardiology Wed, 27 Feb 2013 15:01:31 EST news281199666 Neuroscientists at Georgetown University Medical Center say they have new evidence that challenges scientific dogma involving two fatal neurodegenerative diseases—amyotrophic lateral sclerosis (ALS), and frontotemporal dementia (FTD)—and, in the process, have uncovered a possible therapeutic target as a novel strategy to treat both disorders. http://medicalxpress.com/news/2012-12-protein-garbage-nerve-cells-neurodegenerative.html Medical research Thu, 20 Dec 2012 00:00:09 EST news275158538 Preeclampsia is a serious complication of pregnancy and the major cause of death for both mother and child in Europe and the U.S. It affects about one in 20 pregnancies. The main symptoms are high blood pressure and protein in the urine. The cause of preeclampsia is still unclear. Dr. Florian Herse (Experimental and Clinical Research Center (ECRC) of the Max Delbrück Center (MDC) and the Charité), Dr. Ralf Dechend (ECRC and Helios Klinikum Berlin-Buch) and their collaborators have now identified an enzyme that is overexpressed in affected women and thus apparently contributes to development of the condition. In animal experiments, the researchers inhibited this enzyme and were able to ameliorate the disease process. http://medicalxpress.com/news/2012-11-factor-high-blood-pressure-pregnancy.html Medical research Mon, 26 Nov 2012 09:37:06 EST news273145012 Fujifilm Corporation has developed the micro-needle array which is a new drug administration method that has gained attention for delivering the drug into the body just by attaching it onto the skin. http://medicalxpress.com/news/2012-11-micro-needle-array-method-drug-body.html Medical research Wed, 14 Nov 2012 08:23:40 EST news272103804 At the 1st ECRC "Franz-Volhard" Symposium on September 7, 2012 at the Max Delbrück Center for Molecular Medicine (MDC) in Berlin-Buch, Professor Ken Bernstein reported that in mice an excess of ACE led to a much stronger immune response than usual. In animal experiments, not only could bacterial infections be combated more effectively, but also the growth of aggressive skin cancer (melanoma) in mice could be contained by a stronger response of the immune system. In contrast, if the mice lacked ACE, the immune cells worked less effectively. http://medicalxpress.com/news/2012-09-roles-key-regulatory-enzyme-blood.html Medical research Sat, 08 Sep 2012 04:44:40 EST news266298173 High baseline levels of neuronal activity in the best connected parts of the brain may play an important role in the development of Alzheimer's disease.

In numerous studies, stem cell implantation has substantially improved brain function in experimental animals with brain trauma.

The report describes how scientists from Germany combined two techniques involving the use of site-specific recombinases, or enzymes that facilitate the exchange of genetic material between DNA strands, to help guide exactly where new genetic material is inserted into a cell's DNA. This experimental approach to gene therapy represents an important advance, as successful gene therapy has the potential to correct the root cause of numerous illnesses and health conditions. http://medicalxpress.com/news/2011-11-gene-therapy-tag-exchange.html Genetics Wed, 30 Nov 2011 13:25:25 EST news241881912 (AP) -- Danish researchers can offer some reassurance if you're concerned about your cellphone: Don't worry.
