Currently available antipsychotic drugs, however, only alleviate certain symptoms, with results that vary greatly from patient to patient and frequently cause significant side effects. http://medicalxpress.com/news/2013-02-group-therapy-approach-psychosis-treatment.html Psychology & Psychiatry Fri, 01 Feb 2013 17:00:02 EST news278959578 (HealthDay)—A medication typically prescribed to control high blood pressure that's commonly referred to as a water pill may ease some of the symptoms of autism, researchers say. http://medicalxpress.com/news/2012-12-common-heart-drug-dampen-autism.html Autism spectrum disorders Tue, 11 Dec 2012 09:40:01 EST news274439880 A certain type of immune cell—the regulatory T cell, or Treg for short—is in charge of putting on the brakes on the immune response. In a way, this cell type might be considered the immune system's traffic cops. http://medicalxpress.com/news/2012-11-traffic-cops-immune-molecule-ikbns.html Immunology Thu, 29 Nov 2012 12:11:42 EST news273413486 A new drug may bring help for people with insomnia, according to a study published in the November 28, 2012, online issue of Neurology, the medical journal of the American Academy of Neurology. http://medicalxpress.com/news/2012-11-suvorexant-drug-approach-insomnia.html Neuroscience Wed, 28 Nov 2012 16:31:51 EST news273342621 A small molecule developed at the Weizmann Institute prevents a cancer-causing message from entering the cell nucleus. http://medicalxpress.com/news/2012-06-cancer-messenger.html Cancer Tue, 12 Jun 2012 10:04:34 EST news258714266 Up until now the causes of the development of chronic lymphatic leukaemia, the most common form of cancer of the blood in Europe, have been unknown. At present a cure is not possible. A research group at the MedUni Vienna led by Christoph Steininger of the University Department of Internal Medicine I has now however discovered a lead on the origin of this disease. Says Steiniger: "This could influence the therapy approach taken in treating chronic lymphatic leukaemia." http://medicalxpress.com/news/2012-04-chronic-lymphatic-leukaemia.html Cancer Wed, 11 Apr 2012 08:09:19 EST news253350552 Some unusual alliances are necessary for you to wiggle your fingers, researchers report. http://medicalxpress.com/news/2012-02-unusual-alliances-enable-movement.html Genetics Wed, 08 Feb 2012 10:45:58 EST news247920331 A study carried out by Eric Vivier and Sophie Ugolini at the Marseille-Luminy Centre for Immunology has just reveal a gene in mice which, when mutated, can stimulate the immune system to help fight against tumors and viral infections. Whilst this gene was known to activate one of the body's first lines of defense (Natural Killer, or 'NK' cells), paradoxically, when deactivated it makes these NK cells hypersensitive to the warning signals sent out by diseased cells. http://medicalxpress.com/news/2012-01-immune-infection.html Medical research Fri, 20 Jan 2012 12:36:17 EST news246285367 Potential clues to how autism miswires the brain are emerging from a study of a rare, purely genetic form of the disorders that affects fewer than 20 people worldwide. Using cutting-edge "disease-in a-dish" technology, researchers funded by the National Institutes of Health have grown patients' skin cells into neurons to discover what goes wrong in the brain in Timothy Syndrome.
