Finally ion mobility is used to show the shape of the Abeta 42 peptide and its oligomers. Our experimental and theoretical methods allow us to investigate struct...

A unique twin study on the increased cardiometabolic risk in obesity

...on may determine an individual's susceptibility to weight gain and to the rise of obesity-related health risks. Obesity increases the risk of cardiovascular diseases and diabetes especially when the extra fat is accumulated to central and intra-abdominal depots and when obesity is accompanied by an atheroge...

Bats prey on nocturnally migrating songbirds

"The development of successful strategies for the control of TB in badgers and transmission to cattle will require serious consideration of the likely impact of any interventions on badger social organization," the authors say....

Scripps research team discovers a chemical pathway that causes mice to overeat and gain weight

...p cycle and to eat more. In the study, this led to weight increases of up to 30 percent relative to mice with the receptors. The EP3 receptor is one of four types of receptors for prostaglandin E2 (PGE2), the most important inflammatory mediator that controls a variety of physiological functions includin...

Kansas State study finds new vaccine effective against deadly viral disease affecting swine

Sweat has been the main focus of research on human pheromones, and in fact, mal...

Researchers discover master metabolism regulator with profound effect on fat metabolism

...esize fatty acids. The remarkable rapidity of the weight change in the normal mice occurred because the repressed synthesis of new fats was coupled with the depletion of stored fats in the body. These findings about the crucial regulatory role of GCN2 kinase in the metabolism have major implications for ...

Sea creature's toxin could lead to promising cancer treatment

...rs in the mice, the known drugs caused significant weight loss and loss of white blood cells while AB-5 caused neither side effect. "That the diazonamide toxin blocks mitosis selectively in cancer cells is almost too desirable an outcome to be true," said Dr. Steven McKnight, chairman of biochemistry and s...
