This common endocrine disorder is typically caused by problems of the thyroid gland, and more rarely, by defects in the brain or the pituitary gland (hypophysis). However, a new cause of the disease has been discovered from an unsuspected source and is reported in the journal Nature Genetics. The scientists, led by McGill Professor Daniel Bernard, Department of Pharmacology and Therapeutics in the Faculty of Medicine, identified a new hereditary form of hypothyroidism that is more prevalent in males than in females. This sex bias shone a light on where to look for the underlying cause. http://medicalxpress.com/news/2012-11-thyroid-hormone-deficiency.html Genetics Mon, 12 Nov 2012 13:24:42 EST news271949074 Japanese researchers have created novel cell growth factor FGFC that is considered effective in preventing and treating injury due to high-dose radiation. Until now, there have been insufficient drugs effective in suppression of individual deaths due to radiation exposure. AIST has created the novel, highly stable cell growth factor FGFC and investigated its effect on serious impact to life caused by high-level radiation exposure by experiments on mice. Mice administered FGFC either before or after radiation exposure experienced prolonged survival, demonstrating that FGFC could be effective in preventing and treating fatal radiation injury. The researchers plan to perform a detailed safety evaluation of FGFC. http://medicalxpress.com/news/2012-11-cell-growth-factor-injury-high-level.html Medical research Fri, 02 Nov 2012 10:09:46 EST news271069777 Hong Kong said Thursday it will test babies who have consumed Japanese-made infant formulas found to have insufficient levels of iodine, after the products were ordered off the city's shelves. http://medicalxpress.com/news/2012-08-hong-kong-babies-japanese-formula.html Pediatrics Thu, 09 Aug 2012 03:10:30 EST news263700623 A fungicide used on farm crops can induce insulin resistance, a new tissue-culture study finds, providing another piece of evidence linking environmental pollutants to diabetes.
