Rotten egg gas (hydrogen sulfide) could guard against Alzheimer's disease

Not exactly what you think. But here's the teaser.

"The human body naturally creates small amounts of hydrogen sulfide to help regulate functions throughout the body, from cell metabolism to blood vessel dilation. The rapidly burgeoning field of gasotransmission shows that gases are major cellular messenger molecules, with particular importance in the brain. However, unlike conventional neurotransmitters, gases can't be stored in vesicles. Thus, gases act through very different mechanisms to rapidly facilitate cellular messaging. In the case of hydrogen sulfide, this entails the modification of target proteins by a process called chemical sulfhydration, which modulates their activity, says Solomon Snyder, D.Phil., D.Sc., M.D., professor of neuroscience at the Johns Hopkins University School of Medicine and co-corresponding author on the study.

Studies using a new method have shown that sulfhydration levels in the brain decrease with age, a trend that is amplified in patients with Alzheimer's disease...

Behavioral tests on the mice showed that hydrogen sulfide improved cognitive and motor function by 50% compared with mice that did not receive the injections of NaGYY. Treated mice were able to better remember the locations of platform exits and appeared more physically active than their untreated counterparts with simulated Alzheimer's disease."

Interesting!

Are farts hydrogen sulphide?
