A controversial theory about how diabetes causes extensive tissue damage will appear in the November issue of Diabetes. At stake in the heated debate over the theory are researchers efforts to find new ways to reduce loss of vision, kidney failure, heart damage and other side effects of diabetes.
The American Diabetes Association estimates that 18.2 million Americans have diabetes. Diabetes links to heart attack and stroke make it the sixth leading cause of death, and it is the leading cause of new cases of blindness among adults 20-74 years old. Diabetic nerve damage is a major contributor to non-traumatic lower limb amputations, and diabetic kidney damage creates 43 percent of all cases of end-stage renal disease.
Proponents of the theory argue that the primary cause of such tissue damage is a key compound in energy production other scientists long ago rejected as a contributor to diabetic side effects. The researchers address the many objections and questions raised by critics of their hypothesis in a 47-page appendix available online in conjunction with their study. "The metabolic imbalances caused by diabetes are quite complex, and that has made it very difficult to gain acceptance or even consideration of our hypothesis," says senior investigator Joseph Williamson, M.D, a retired pathology faculty member at Washington University School of Medicine in St. Louis. "Being able to publish the online appendix finally gave us the room we needed to respond to everyones concerns."

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
