Out of my way, nurse!" The quick-thinking young doctor charges the defibrillator paddles and places them on the chest of the lifeless patient, whose cardiac monitor is showing a straight green line. The patient gets a huge dose of electricity; his back arches and his limp body lifts up off the bed with the shock. http://medicalxpress.com/news/2013-05-medical-myth-flatlining-patients-life.html Cardiology Tue, 14 May 2013 09:10:01 EST news287740616 Cancer cells break down sugars and produce the metabolic acid lactate at a much higher rate than normal cells. This phenomenon provides a telltale sign that cancer is present, via diagnostics such as PET scans, and possibly offers an avenue for novel cancer therapies. Now a team of Chilean researchers at The Centro de Estudios Científicos (CECs), with the collaboration of Carnegie's Wolf Frommer, has devised a molecular sensor that can detect levels of lactate in individual cells in real time. http://medicalxpress.com/news/2013-03-cancer-diagnostic-technique-debuts.html Cancer Thu, 14 Mar 2013 11:21:05 EST news282478855 Researchers have found new evidence that metabolic stress can increase the onset of atrial arrhythmias, such as atrial fibrillation (AF), a common heart condition that causes an irregular and often abnormally fast heart rate. The findings may pave the way for the development of new therapies for the condition which can be expected to affect almost one in four of the UK population at some point in their lifetime. http://medicalxpress.com/news/2013-01-common-heart-condition.html Cardiology Tue, 08 Jan 2013 09:17:14 EST news276859023 (Medical Xpress)—In a new study published in the scientific journal Circulation, scientists at Karolinska Institutet and Karolinska University Hospital show that an enzyme called arginase might have a key part to play in the development of cardiovascular disease in patients who already have type II diabetes. According to the team, arginase prevents the formation of protective nitrogen oxide in the blood vessels, and treatments that inhibit this enzyme reduce the risk of angina in diabetics. http://medicalxpress.com/news/2012-11-enzyme-angina-diabetics.html Cardiology Tue, 27 Nov 2012 06:55:41 EST news273221566 New treatments to lessen the severity of the more than 21,000 Traumatic Brain Injury (TBI) cases that occur in Australia each year are on the horizon. http://medicalxpress.com/news/2012-07-traumatic-brain-injury.html Neuroscience Thu, 19 Jul 2012 19:00:05 EST news261932619 Dr Changfa Guo, Professor Chunsheng Wang and their co-investigators from Zhongshan hospital Fudan University, Shanghai, China have established a novel hyperbranched poly(amidoamine) (hPAMAM) nanoparticle based hypoxia regulated vascular endothelial growth factor (HRE-VEGF) gene therapy strategy which is an excellent substitute for the current expensive and uncontrollable VEGF gene delivery system. This discovery, reported in the June 2012 issue of Experimental Biology and Medicine, provides an economical, feasible and biocompatible gene therapy strategy for cardiac repair. http://medicalxpress.com/news/2012-07-economical-effective-biocompatible-gene-therapy.html Medical research Fri, 06 Jul 2012 13:30:18 EST news260800122 Patients with cardiovascular disease will now benefit from a powerful new molecular imaging tool to detect disease in the main arteries supplying oxygen to the heart, say researchers presenting studies at the Society of Nuclear Medicine's 2012 Annual Meeting. http://medicalxpress.com/news/2012-06-molecular-imaging-coronary-arteries-disease.html Cardiology Mon, 11 Jun 2012 14:20:01 EST news258639533 People with heart disease may not be able to compensate for their bodies' higher demand for oxygen when inhaling cold air, according to Penn State researchers, making snow shoveling and other activities dangerous for some. http://medicalxpress.com/news/2012-02-cold-air-chills-heart-oxygen.html Cardiology Tue, 28 Feb 2012 12:10:01 EST news249652104 Treating brain tumors with whole brain radiation therapy can damage healthy brain tissue, but a new study in mice reveals that limiting the oxygen supply, or hypoxia, can alleviate some of the cognitive impairment caused by the radiation.
