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 Researchers at The Johns Hopkins University and Yale University have discovered that a specialized receptor, normally found in the nose, is also in blood vessels throughout the body, sensing small molecules created by microbes that line mammalian intestines, and responding to these molecules by increasing blood pressure. The finding suggests that gut bacteria are an integral part of the body's complex system for maintaining a stable blood pressure. http://medicalxpress.com/news/2013-02-blood-vessels-gut-microbes-pressure.html Medical research Tue, 26 Feb 2013 11:35:43 EST news281100934 A new type of prophylactic treatment for brain injury following prolonged epileptic seizures has been developed by Emory University School of Medicine investigators. http://medicalxpress.com/news/2013-02-potential-treatment-prolonged-seizures.html Neuroscience Mon, 11 Feb 2013 15:00:19 EST news279805030 (Medical Xpress)—Researchers at the University of Virginia School of Medicine have shed new light on blood pressure regulation with the discovery of an unexpected mechanism by which hemoglobin controls the delivery of nitric oxide. The findings may point to a new therapeutic target for treating high blood pressure and may have far-reaching implications for many organ systems and illnesses. http://medicalxpress.com/news/2012-11-discovery-nitric-oxide-delivery-mechanism.html Medical research Wed, 14 Nov 2012 08:12:06 EST news272103092 Researchers from the Peninsula College of Medicine and Dentistry, University of Exeter, in collaboration with colleagues from Rutgers University, Newark and University College London, have furthered understanding of the mechanism by which the cells that insulate the nerve cells in the peripheral nervous system, Schwann cells, protect and repair damage caused by trauma and disease. http://medicalxpress.com/news/2012-06-inproved-peripheral-nervous.html Neuroscience Fri, 15 Jun 2012 10:13:38 EST news258974007 Scientists at Emory University School of Medicine have identified a new group of compounds that may protect brain cells from inflammation linked to seizures and neurodegenerative diseases. http://medicalxpress.com/news/2012-02-class-potential-drugs-inhibits-inflammation.html Neuroscience Tue, 14 Feb 2012 11:14:10 EST news248440412 Within the next 20 years it is expected the number of people with Alzheimer's disease (AD) will double from its current figure of half a million to one million. A new study has looked at whether certain types of drugs used to treat high blood pressure, also called hypertension, might have beneficial effects in reducing the number of new cases of Alzheimer's disease each year. http://medicalxpress.com/news/2011-10-hypertension-drugs-people-alzheimer.html Alzheimer's disease & dementia Mon, 17 Oct 2011 10:06:58 EST news238064798 Heart rate and blood pressure regulation may hold the key to treating unexplained chronic nausea in children. In a new study by researchers at Wake Forest Baptist Medical Center, a drug commonly used to treat a condition known as orthostatic intolerance (OI), which causes dizziness and occasional fainting when patients stand for long periods, was shown to reduce debilitating chronic nausea in patients. http://medicalxpress.com/news/2011-08-heart-key-unexplained-nausea-youths.html Diseases, Conditions, Syndromes Thu, 25 Aug 2011 10:37:43 EST news233487441 Researchers at the Johns Hopkins University School of Medicine have found a protein normally involved in blood pressure regulation in a surprising place: tucked within the little "power plants" of cells, the mitochondria. The quantity of this protein appears to decrease with age, but treating older mice with the blood pressure medication losartan can increase protein numbers to youthful levels, decreasing both blood pressure and cellular energy usage. The researchers say these findings, published online during the week of August 15, 2011, in the Proceedings of the National Academy of Sciences, may lead to new treatments for mitochondrial–specific, age-related diseases, such as diabetes, hearing loss, frailty and Parkinson's disease. http://medicalxpress.com/news/2011-08-cell-power-declines-age-rejuvenated.html Medical research Tue, 16 Aug 2011 17:04:51 EST news232733068
