Cancer chemotherapy can cause peripheral neuropathy—nerve damage often resulting in pain and muscle weakness in the arms and legs. Now, researchers at Albert Einstein College of Medicine of Yeshiva University have discovered that chemo also induces an insidious type of nerve damage inside bone marrow that can cause delays in recovery after bone marrow transplantation. The findings, made in mice and published online today in Nature Medicine, suggest that combining chemotherapy with nerve-protecting agents may prevent long-term bone marrow injury that causes anemia and may improve the success of bone marrow transplants. http://medicalxpress.com/news/2013-05-discovery-chemotherapy-induced-anemia.html Medical research Sun, 05 May 2013 13:00:01 EST news286954775 Teenagers who are highly exposed to violent video games—three or more hours per day—show blunted physical and psychological responses to playing a violent game, reports a study in the May issue of Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society. http://medicalxpress.com/news/2013-05-violent-video-games-effects-highly-exposed.html Psychology & Psychiatry Fri, 03 May 2013 13:11:19 EST news286805472 Up to 10 per cent of patients with high blood pressure are resistant to treatment, which puts them at increased risk of cardiovascular events, including heart attacks. Clinical trials show that catheter-based renal denervation reduces blood pressure in patients who do not respond to conventional drug therapy. http://medicalxpress.com/news/2013-04-esc-patients-centres-renal-denervation.html Cardiology Thu, 25 Apr 2013 18:30:25 EST news286133398 (Medical Xpress)—Imagine you are driving a car, and the harder you press on the accelerator, the harder an invisible foot presses on the brake. That's what happens when obese people diet – the less food they eat, the less energy they burn, and the less weight they lose. http://medicalxpress.com/news/2013-02-brain-circuit-hard-obese-people.html Medical research Wed, 06 Feb 2013 10:59:07 EST news279370741 Obesity and its related conditions such as type 2 diabetes, cardiovascular disease and stroke are among the most challenging of today's healthcare concerns. http://medicalxpress.com/news/2013-01-scientists-culprit-obesity-associated-high-blood.html Medical research Thu, 31 Jan 2013 12:00:05 EST news278854273 Genome sequencing data once regarded as junk is now being used to gain important clues to help understand disease. The latest example comes from the St. Jude Children's Research Hospital – Washington University Pediatric Cancer Genome Project, where scientists have developed an approach to mine the repetitive segments of DNA at the ends of chromosomes for insights into cancer. http://medicalxpress.com/news/2013-01-gene-sequencing-junk-clues-cancer.html Cancer Thu, 24 Jan 2013 13:41:21 EST news278257273 Researchers at Karolinska Institutet in Sweden have managed to graft beta cells into the eyes of mice in order to study them in a living organism over a prolonged period of time. As a result, the group and a team of colleagues from the University of Miami have gained detailed knowledge of how the autonomic nervous system regulates beta-cell insulin secretion. http://medicalxpress.com/news/2012-12-nerves-insulin-secretion.html Medical research Mon, 10 Dec 2012 15:00:01 EST news274361411 New research from Mount Sinai School of Medicine sheds light on how overeating can cause a malfunction in brain insulin signaling, and lead to obesity and diabetes. Christoph Buettner, MD, PhD, Associate Professor of Medicine (Endocrinology, Diabetes and Bone Disease) and his research team found that overeating impairs the ability of brain insulin to suppress the breakdown of fat in adipose tissue. http://medicalxpress.com/news/2012-10-overeating-impairs-brain-insulin-function.html Overweight and Obesity Wed, 17 Oct 2012 16:21:34 EST news269709688 Researchers at the Hebrew University of Jerusalem have discovered that a neuronal pathway—part of the autonomic nervous system—reaches the bones and participates in the control of bone development. http://medicalxpress.com/news/2012-09-neural-brain-to-bone-pathway-skeletal.html Medical research Mon, 03 Sep 2012 10:27:26 EST news265886837 Stress can promote breast cancer cell colonization of bone, Vanderbilt Center for Bone Biology investigators have discovered. http://medicalxpress.com/news/2012-07-stress-fuels-breast-cancer-metastasis.html Cancer Tue, 17 Jul 2012 17:00:02 EST news261756692 Many chronic heart failure patients struggle with not just strenuous activity but even the essentials such as moderate exercise and normal breathing. Research revealed at the Society of Nuclear Medicine's 2012 Annual Meeting presents an overnight breathing treatment called adaptive servo-ventilation as a potential protocol for energizing the heart by increasing activity in the sympathetic nervous system. An aspect of the nervous system, the main function of the sympathetic nervous system is to mobilize the body, commonly known as the "fight-or-flight" impulse. http://medicalxpress.com/news/2012-06-treatment-cardiac-function-nerve-health.html Cardiology Mon, 11 Jun 2012 14:30:01 EST news258639558 Research presented at the Society of Nuclear Medicine's 59th Annual Meeting reveals that patients with differentiated thyroid cancer live as long as people in perfect health, unless they are in the minority and have reached the most advanced stages of disease.

Published online in the Journal of Hypertension, the study demonstrates that excess salt stimulates the sympathetic nervous system to produce adrenalin, causing artery constriction and hypertension. http://medicalxpress.com/news/2012-01-link-salt-hypertension.html Health Wed, 11 Jan 2012 10:15:27 EST news245499312 Either heart failure or diabetes alone is bad enough, but oftentimes the two conditions seem to go together.
