A recent study conducted by a group of German scientists revealed the presence of a previously unknown cell in the urethra of mice. These chemosensory cholinergic brush cells are in close contact to sensory neurons that express cholinergic receptors. http://medicalxpress.com/news/2013-03-uncovers-cells-urethra-hazardous-substances.html Medical research Fri, 15 Mar 2013 03:00:01 EST news282499052 German scientists from the Bonn University Hospital successfully tested a method in mice allowing the morphological and functional sequelae of a myocardial infarction to be reduced. Tiny gas bubbles are made to oscillate within the heart via focused ultrasound - this improves microcirculation and decreases the size of the scar tissue. The results show that the mice, following myocardial infarction, have improved cardiac output as a result of this method, as compared to untreated animals. http://medicalxpress.com/news/2013-02-microbubbles-myocardial-remodelling-infarction.html Medical research Thu, 21 Feb 2013 10:01:00 EST news280663253 Twelve million Germans suffer from periodontitis, an inflammation that can lead to the loss of teeth if left untreated. Bleeding gums during brushing or when biting into an apple could be an indication of periodontitis, an inflammatory disease of the tissues that surround and support the teeth. Bacterial plaque attacks the bone, meaning teeth can loosen over time and in the worst case even fall out, as they are left without a solid foundation to hold them in place. Furthermore, periodontitis also acts as a focal point from which disease can spread throughout the entire body: If the bacteria, which can be very aggressive, enters the bloodstream, they can cause further damage elsewhere. Physicians suspect there is a connection between periodontitis pathogens and the sort of cardiovascular damage that can cause heart attacks or strokes. In order to stop the source of inflammation, dentists remove dental calculus and deposits from the surface of teeth, but this is often not enough; aggressive bacteria can only be eliminated with antibiotics. http://medicalxpress.com/news/2013-02-millions-germans-periodontitis.html Dentistry Fri, 01 Feb 2013 06:27:18 EST news278922414 German scientists have demonstrated a new way to investigate mechanisms at work in Alzheimer's and other neurodegenerative diseases, which also could prove useful in the search for effective drugs. For new insights, they turned to the zebrafish, which is transparent in the early stages of its life. The researchers developed a transgenic variety, the "MitoFish," that enables them to see – within individual neurons of living animals – how brain diseases disturb the transport of mitochondria, the power plants of the cell. http://medicalxpress.com/news/2012-12-see-through-mitofish-window-brain-diseases.html Neuroscience Wed, 05 Dec 2012 10:53:09 EST news273927179 German scientists at Charité – Universitätsmedizin Berlin and Labor Berlin GmbH have succeeded in clarifying the molecular signature of the viruses that lead to an increasing size and number of hantavirus outbreaks in Germany. http://medicalxpress.com/news/2012-09-molecular-signature-hantavirus-infection-humans.html Diseases, Conditions, Syndromes Mon, 03 Sep 2012 11:00:02 EST news265887125 Biotech giant Amgen said Thursday it was buying the German-American cancer research firm Micromet, giving it access to Micromet's promising leukemia therapy. http://medicalxpress.com/news/2012-01-amgen-micromet-anti-leukemia-drug.html Other Thu, 26 Jan 2012 13:57:46 EST news246808660
