Stress promotes neuropathological changes that are also seen in Alzheimer's disease. Scientists from the Max Planck Institute of Psychiatry in Munich have discovered that the increased release of stress hormones in rats leads to generation of abnormally phosphorylated tau protein in the brain and ultimately, memory loss. http://medicalxpress.com/news/2011-05-stress-alzheimer-disease.html Diseases, Conditions, Syndromes Thu, 26 May 2011 12:58:21 EST news225633476 Obese individuals typically suffer more medical problems than their leaner counterparts. They are more likely to be diagnosed with insulin resistance, diabetes, increased stress hormones, hypothyroidism, and sleep apnea. Researchers at the Georgia Health Sciences University in Augusta have also found the potential for something else, using an animal model. They have found that a master clock gene – which regulates the cardiovascular system – does not fluctuate regularly as it does in non-obese animals. This means that a key gene clock of the cardiovascular system does not work properly when obesity is present. The findings are believed to be the first of their kind. http://medicalxpress.com/news/2011-04-obesity-circadian-clock-cardiovascular.html Medical research Mon, 11 Apr 2011 13:08:28 EST news221746099
