Red Meat helps boosting a food poison Germ

Tags: bacterium, food poisoning, HUS

Dairy products scientists say that they have found a bacterium that become the cause of food poisoning by targeting a non-human molecule that can be absorbed into the body through red meat.

A potent bacterial toxin known as Subtilase cytotoxin is produced by some kinds of E. coli bacteria that targets on human cells with a non-human cellular molecule on their surface. It seems that N-glycolylneuraminic acid (Neu5Gc) is one of its favorite targets. N-glycolylneuraminic acid is a type of glycan or sugar molecule and its high levels are found in red meat and dairy products.

Subtilase cytotxin leads to bloody diarrhea and can become the cause of haemolytic uraemic syndrome (HUS) that is a potentially fatal disease.

The study has been published online in the journal Nature Oct. 29 issue.

More drinking, more Shrinkage of the brain

The excessive alcohol drinking, shrinks’ brain, a new study has found.

“The take-home message is that, if you drink a lot, you’re going to hurt your brain. This is something we knew, but this is a huge study that quantifies that.” said Rajesh Miranda, an associate professor of Health Science Center College of Medicine.

Brain degenerates naturally with aging, at a rate of about 1.9 percent per decade. Simultaneously, the brain gains white matter lesions. Both of these changes are accompanist of dementia and cognitive decline.

For the study, researchers conducted MRI and health examination on 1,839 adults, aged up to 60. None of the participants had evidence of clinical dementia or had suffered a stroke.
