A new therapy being studied in non-human primates by researchers at Wake Forest Baptist Medical Center and colleagues is demonstrating promise as a potential tool for combating cardiovascular disease by increasing good cholesterol and lowering triglycerides in the blood. Supported by the National Institutes of Health and the Canadian Institutes of Health Research, the preclinical findings appear in this week’s issue of the journal Nature.

Salmon, a natural source of omega-3. Professor Breier, who leads an international research team, says omega-3s are especially beneficial for health in ageing because they improve carbohydrate and fat metabolism. His research found a diet high in omega-3 fatty acids helps to burn metabolic fuels (glucose and fat) better, and can regulate energy storage across different tissues.

In a development that sheds new light on the pathology of Alzheimer’s disease (AD), a team of Whitehead Institute scientists has identified connections between genetic risk factors for the disease and the effects of a peptide toxic to nerve cells in the brains of AD patients.

Pythons are known for their enormous appetites. In a single meal they can devour animals at least as big as they are — deer, alligators pigs and house pets, for example. Equally remarkable is what happens inside the python as it digests its prey.

The pigmented cells called melanocytes aren't just for making freckles and tans. Melanocytes absorb ultraviolet light, protecting the skin from the harmful effects of the sun. They also are the cells that go haywire in melanoma, as well as in more common conditions as vitiligo and albinism.Naturally, researchers would love to study melanocytes in the laboratory. There's just one problem -- melanocytes from adult skin don't grow very well in the lab.

Modern medicine’s ability to save lives through organ transplantation has been revolutionized by the development of drugs that prevent the human body from rejecting the transplanted organ. But those antirejection drugs have their own side effects — sometimes serious.

Scientists in the US were able to normalise blood sugar levels in diabetic mice by injecting them with a compound, nicotinamide mononucleotide (NMN). At the same time the jabs lowered raised levels of cholesterol and triglyceride blood fats.

Over the next five years, National Institutes of Health (NIH)-funded researchers will extensively test and generate data about mice with disrupted genes to gain clues about human diseases. NIH today awarded a set of cooperative agreements totaling more than $110 million to begin the second phase of the Knockout Mouse Project (KOMP).

A protein linked to Alzheimer's disease kills nerve cells that detect odors, according to an animal study in the September 28 issue of The Journal of Neuroscience. The findings shed light on why people with Alzheimer's disease often lose their sense of smell early on in the course of the disease.
