Autism conference reports advances in early diagnosis, role of immune system and more

...eloping children revealed differences in proteins, metabolites and the immune system. These included elevated levels of immune system B cells and natural killer cells in the autistic group, and more than 100 proteins that the two groups expressed differently. Behavior: Researchers identified a variety of beha...

Scientists report strong evidence of alterations in blood samples of children with autism

Estrogen, estrogen-like drugs' ability to protect brain after stroke under study

...ems a natural fit because estrogen and some of its metabolites have been shown in many systems to be a free-radical scavenger. Dr. Brann's preliminary studies support this, showing dramatically reduced levels of toxic superoxide, the major free radical, in stroke models treated with estrogen and tamoxifen before...

Flavanols key to potential chocolate benefits

Vitamin D and calcium supplements have varied effects on breast cancer risk

...wski explained that "planned analyses of vitamin D metabolites in the blood may help interrupt the findings." Previous observational studies have suggested that vitamin D and calcium may protect against breast cancer. Because natural sources of vitamin D are limited (mostly sun exposure and oily fish), vitamin D...

Compound in dairy products targets diabetes

...cal purpose is to sense fatty acids and fatty acid metabolites within the cell, says Vanden Heuvel. When the synthetic drugs interact with these protein receptors, it turns the receptor "on," making it an active form of the protein, which then interacts with DNA and regulates gene expression. This increases t...

The mice in the lupus group had significantly poorer cognitive function at seven weeks, tracking the decline in the glutamate/glutamine ratio. Cognitive function "continued to deteriorate furthe...

Brains can recover from alcoholic damage but patients should stop drinking as soon as possible
