A drug developed at Linköping University in Sweden protects against the side effects of cancer treatments while strengthening the effects on the tumour. An international drug evaluation is now starting up on a larger group of patients. http://medicalxpress.com/news/2013-01-drug-side-effects-chemotherapy.html Cancer Tue, 22 Jan 2013 07:36:42 EST news278062507 (Medical Xpress)—Scientists at Karolinska Institutet in Sweden have presented a new principle for fighting bacterial infections, in other words, a new type of antibiotic, in the FASEB Journal. The new antibiotic mechanism is based on selectively blocking the thioredoxin system in the cells, which is crucial to the growth of certain bacteria. Scientists hope to be able to treat such conditions as stomach ulcers, TB and MRSA. http://medicalxpress.com/news/2012-12-antibiotics-based-principle-defeat-mrsa.html Medical research Tue, 18 Dec 2012 10:21:09 EST news275048442 Scientists have been trying to explain the causes of diabetes for many years. Researchers at the University of Copenhagen and Novo Nordisk A/S have now shown that the increased activity of one particular iron-transport protein destroys insulin-producing beta cells. In addition, the new research shows that mice without this iron transporter are protected against developing diabetes. These results have just been published in the prestigious journal Cell Metabolism. http://medicalxpress.com/news/2012-09-diabetes-linked-iron.html Diabetes Thu, 20 Sep 2012 12:20:45 EST news267362437 (Medical Xpress) -- The findings of new research from UCD Conway Institute and the National Children’s Research Centre shows oxygen radicals are the first line of defence against gastroenteritis caused by Campylobacter organisms. http://medicalxpress.com/news/2012-08-oxygen-radicals-defend-intestine-gastroenteritis.html Medical research Tue, 21 Aug 2012 08:35:12 EST news264756697 Why do we age, and what makes some of us live longer than others?
