Findings further link inflammation, obesity, and type-2 diabetes
Chronic inflammation is being implicated in diseases as widespread as cancer, heart disease, Alzheimers disease, and most recently, diabetes and obesity. The role of the hormone resistin in people with these diseases has been questioned because it is primarily secreted by immune cells called macrophages in humans rather than fat cells, as in mice. Nevertheless, resistin is elevated in some people with diabetes and obesity. Higher levels of resistin are associated with insulin resistance. But what is the connection among inflammation, insulin resistance, and obesity?
Insulin resistance, which occurs when muscle, fat, and liver cells fail to use insulin effectively to regulate blood sugar, usually precedes type-2 diabetes and is part of metabolic syndrome. A new study from the laboratory of Mitch Lazar, MD, PhD, Chief of the Division of Endocrinology, Diabetes and Metabolism at the University of Pennsylvania School of Medicine, has found that by simulating inflammation in human macrophages and patients levels of resistin substantially increase. In people, the resistin level in blood increases by about 400 percent. "This suggests that resistin is part of the inflammatory process," says Lazar. "This leads us to hypothesize that human resistin also contributes to insulin resistance." He and colleagues published their findings in the November 30 issue of PloS, Medicine.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
