Pricking a finger everyday is just part of everyday life for many diabetes patients. A non-invasive measurement approach could release them from the constant pain of pin pricks. The linchpin is a biosensor engineered by Fraunhofer researchers: A tiny chip combines measurement and digital analysis – and can be radioed to a mobile device. http://medicalxpress.com/news/2012-09-glucose-needle.html Diseases, Conditions, Syndromes Tue, 04 Sep 2012 17:30:22 EST news265998600 Macrophages playing an important role in the immune system eat and fight against pathogens and foreign substances in the very beginning of infection. In this condition, macrophages produce reactive oxygen species for sterilization. However, the relation with the temperature sensor was not previously known. http://medicalxpress.com/news/2012-04-immune-cells-macrophages-body-temperature.html Immunology Mon, 09 Apr 2012 15:00:18 EST news253186786 A Queen's University infectious disease expert has collaborated in the development of a disinfection system that may change the way hospital rooms all over the world are cleaned as well as stop bed bug outbreaks in hotels and apartments. http://medicalxpress.com/news/2011-12-disinfection-technique-revolutionize-hospital-room.html Diseases, Conditions, Syndromes Fri, 09 Dec 2011 10:38:37 EST news242649510 Hydrogen peroxide isn't just that bottled colorless liquid in the back of the medicine cabinet that's used occasionally for cleaning scraped knees and cut fingers. http://medicalxpress.com/news/2011-11-hydrogen-peroxide-clues-immunity-wound.html Medical research Mon, 21 Nov 2011 11:43:11 EST news241098168 Working with lab cultures and mice, Johns Hopkins scientists have found that a strain of the common gut pathogen Bacteroides fragilis causes colon inflammation and increases activity of a gene called spermine oxidase (SMO) in the intestine. The effect is to expose the gut to hydrogen peroxide – the caustic, germ-fighting substance found in many medicine cabinets -- and cause DNA damage, contributing to the formation of colon tumors, say the scientists. http://medicalxpress.com/news/2011-11-common-bacteria-colon-tumors-peroxide-producing.html Cancer Sat, 05 Nov 2011 05:20:10 EST news239682490 By consuming fewer calories, ageing can be slowed down and the development of age-related diseases such as cancer and type 2 diabetes can be delayed. The earlier calorie intake is reduced, the greater the effect. Researchers at the University of Gothenburg have now identified one of the enzymes that hold the key to the ageing process. http://medicalxpress.com/news/2011-10-longer-calories.html Medical research Mon, 31 Oct 2011 15:08:08 EST news239292467 Cardiologists who perform heart operations using x-ray guided catheters are exposed to ionising radiation at levels two to three times higher per year than those experienced by radiologists. Now, new research has found the first evidence that these constant, high levels of exposure cause changes at cell level that might represent the body's way of protecting itself against the harmful effects of radiation. http://medicalxpress.com/news/2011-08-physicians-exposure-prompt-cellular-body.html Other Wed, 24 Aug 2011 04:10:24 EST news233376865 Don't Cross Your Eyes...They'll Get Stuck that Way!, a new book by myth-fighting Indiana University School of Medicine pediatricians Aaron Carroll, M.D., M.S., and Rachel Vreeman, M.D., M.S., debunks the pearls of medical wisdom that many people and even their physicians believe are true.

UCLA researchers Sandra Rieger and Alvaro Sagasti found that a chemical signal released by wounded skin cells promotes the regeneration of sensory fibers, thus helping to ensure that touch sensation is restored to healing skin. They discovered that the reactive oxygen species hydrogen peroxide, which is found at high concentrations at wounds, is a key component of this signal. http://medicalxpress.com/news/2011-05-power-hydrogen-peroxide.html Medical research Tue, 24 May 2011 17:47:20 EST news225478022 Researchers have developed an effective technique that uses gene therapy on stem cells to correct chronic granulomatous disease (CGD) in cell culture, which could eventually serve as a treatment for this rare, inherited immune disorder, according to a study published in Blood, the Journal of the American Society of Hematology. http://medicalxpress.com/news/2011-04-gene-therapy-technique-ips-cells.html Medical research Thu, 28 Apr 2011 11:32:02 EST news223209111
