Inflammatory joint disease (arthritis) is affecting more and more, and especially older, people. In a recent survey by Statistik Austria, 39 per cent of people over the age of 60 stated that they have a form of arthritis. One particular form of the condition is osteoarthrosis, which is wear and tear on the joints. A team of researchers at the University Department of Orthopaedics at the MedUni, led by Stefan Tögel, is focusing on glycobiology in orthopaedics and has now discovered a factor that plays an important role in the development of osteoarthrosis. http://medicalxpress.com/news/2012-12-factor-involved-painful-joint.html Medical research Wed, 05 Dec 2012 09:25:52 EST news273921933 Researchers at Karolinska Institutet in Sweden have shown that the cells that produce glucagon are stimulated by the hormone itself.

This means that a feedback system is at work in the body, whereby hormone secreting cells receive an immediate signal to produce more of the hormone. http://medicalxpress.com/news/2012-12-glucagon-synthesis.html Medical research Mon, 03 Dec 2012 15:00:10 EST news273755404
