While their study focused on man's best friend, the treatment could help restore vision in people, too. http://medicalxpress.com/news/2013-04-one-two-key.html Ophthalmology Tue, 09 Apr 2013 09:38:51 EST news284719124 Muscle withering can occur as part of the progression of many diseases, including cancer and muscular dystrophy, as well as during the normal aging process. Cellular organelles known as mitochondria provide energy for muscle contraction, and their fragmentation within muscle cells can lead to muscle wasting. Now, a team of researchers led by Ravi Kambadur at the A*STAR Singapore Institute for Clinical Sciences has identified a key role for mitochondrial E3 ubiquitin protein ligase 1 (Mul1) in mitochondrial fragmentation. Such fragmentation occurs in response to stimuli that cause muscle loss. http://medicalxpress.com/news/2013-03-cell-metabolism-muscle-loss-mitochondrial.html Medical research Wed, 13 Mar 2013 08:00:01 EST news282379201 Infectious disease experts have long thought that children, teenagers and young adults who are chronically infected with the hepatitis B virus (HBV) lack the immune cells needed to fight this pathogen. As such, physicians currently withhold therapeutic interventions from younger patients until they have reached an advanced age—typically around 30 years old—at which time the immune system is thought to have 'awakened' to the virus. http://medicalxpress.com/news/2013-02-exposure-hepatitis-virus-immunity-young.html Diseases, Conditions, Syndromes Wed, 27 Feb 2013 08:40:02 EST news281175873 People with cystic fibrosis (CF) will be able to access the latest research findings about their condition, volunteer for clinical trials and influence the direction of future scientific studies through a new website being launched later this week.  http://medicalxpress.com/news/2013-01-website-cystic-fibrosis-patients.html Diseases, Conditions, Syndromes Tue, 08 Jan 2013 06:11:13 EST news276847866 In a study published today in Pediatrics, scientists at Umeå University in Sweden conclude that giving iron supplements to low birth weight infants reduces the risk of behavior problems like ADHD later in life. http://medicalxpress.com/news/2012-12-iron-supplements-adhd-birth-weight.html Attention deficit disorders Mon, 10 Dec 2012 08:56:51 EST news274352161 A new study from Karolinska Institutet in Sweden shows, that a technique for measuring bone density called digital X-ray radiogrammetry (or DXR) used on standard hand radiographs can help to identify patients with a higher risk of hip fracture. The researchers believe that DXR, which is fully comparable with other, more costly methods, can be used preventively to identify people in the risk zone for osteoporosis – a disease estimated to effect some 200 million women worldwide. http://medicalxpress.com/news/2012-11-method-bone-density-hip-fractures.html Diseases, Conditions, Syndromes Mon, 19 Nov 2012 10:46:46 EST news272544389 By studying a specific part of the male DNA, it may be possible to refine the interpretation of PSA tests.
