Single Infusion of islet cells surpasses previous success
esearchers at the University of Minnesotas Diabetes Institute for Immunology and Transplantation (DIIT) and the University of California San Francisco (UCSF) Diabetes Center have achieved insulin independence in four of six patients with long-term Type 1 diabetes using one infusion of insulin-producing "islet" cells from a single donor pancreas.
Individuals in whom Type 1 diabetes was complicated by hypoglycemic unawareness participated in this trial. The combination of improved islet preparation techniques and optimized recipient immunosuppression contributed to the successful study outcome. Insulin independence has now been maintained for more than one year in four recipients, for more than two years in three recipients, and for more than three years in two recipients. The study, funded primarily by the Juvenile Diabetes Research Foundation, is published in the March issue of the American Journal of Transplantation.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
