Important — “The researchers found that sedentary behavior is a significant predictor of thinning of the MTL and that physical activity, even at high levels, is insufficient to offset the harmful effects of sitting for extended periods”

— In the study, both (A) Total medial temporal lobe (MTL) and (B) parahippocampal thickness correlated inversely with hours of sitting/day, controlling for age.

Researchers at Gladstone Institutes in San Francisco report that a gene variant associated with Alzheimer’s works differently in mice and humans, and they also demonstrate how modifying this gene could potentially prevent the plaques associated with Alzheimer’s from forming and damaging the brain.

An ApoE3 gene variant is associated with Alzheimer’s disease

The gene apolipoprotein E3 (ApoE3) has a variant known as ApoE4, which is associated with the development and progress of Alzheimer’s disease. People with just one copy of the ApoE4 gene are at twice the risk as people without this gene variant. Some people even have two copies of the ApoE4 gene, which makes their risk of Alzheimer’s a staggering twelve times greater.

A key trial, based in the U.S., looks to test if stem cells can help treat autism.

Farts may stink to high heaven, but a new study suggests that the gas responsible for that foul odor may actually extend a person’s time on earth.

Scientists in the UK claim that hydrogen sulfide, the stinky compound that smells like rotten eggs which contributes to the flatulence stench, could have amazing health benefits.

Hydrogen sulfide can be toxic, but tiny amounts have been shown to help protect the mitochondria, which are known as the “powerhouses” of cells.

Klotho is a membrane-spanning protein expressed predominantly in the kidney, as well as in the brain.

Ageing is a regulated process in which hormones have pivotal roles. Crystal structures of two hormone co-receptors should be informative for drug discovery focused on age-related disorders.

Scientists from Wake Forest Baptist Medical Center partnered with researchers from the University of Southern California to develop an innovative procedure to give hope to people struggling with remembering important information. A new implant uses a person’s own memory patterns in order to boost the brain’s natural ability to encode those memories and recall them quickly. There has been a reported 35 to 37 % increase in short-term memory performance.

“This is the first time scientists have been able to identify a patient’s own brain cell code or pattern for memory and, in essence, ‘write in’ that code to make existing memory work better, an important first step in potentially restoring memory loss,” said the study’s lead author Robert Hampson, Ph.D., professor of physiology/pharmacology and neurology at Wake Forest Baptist.

Epilepsy patients from Wake Forest Baptist were surgically implanted with electrodes in the various parts of their brains. The electronic prosthetic system is based on a multi-input-multi-output (or MIMO) mathematical model to influence the patterns of neurons firing within the hippocampus.
