McBride shows DNA detective work with paper-eating bacteria that 'glide'

...fficult to break down. McBride hypothesizes that digestion of cellulose and chitin may also be linked to cell...chitin," he says. "This suggests that motility and digestion of some carbohydrate polymers may be connected in both gliding microbes." McBride and his students...

Parallel evolution: Proteins do it, too

...duplication, the gene is supposed to do both jobs: digestion and degrading double-stranded RNA. After duplication, one copy seems to retain the activity of degrading double-stranded RNA while the other copy has adapted to changed pH in the small intestine so it can better digest food." Even after clearly demo...

Scientists take 'snapshots' of enzyme action

...o oxygenate trimethylamine, a byproduct of protein digestion released by bacteria living in the gut. People with the disorder release trimethylamine through breath, sweat, and urine, producing a fish-like odor that can be embarrassing and result in psychological effects such as withdrawal and depression. Peop...

Johns hopkins researchers find link between cell's energy use and genome health

...remember telephone numbers or that preventing such digestion makes you forget them," Boeke added. The research, to be published in the July 21 issue of Molecular Cell, could lead to new strategies one day to slow aging and treat cancer, events closely linked to changes in gene control and energy metabolism. ...

New evidence questions the simple link between prion proteins and madcow disease

...ues. This will then be exposed to 48 hours or more digestion before it arrives in the gut, and our experiments ... of this being due to an invisible sub-fraction of digestion resistant PrP molecules is unlikely. The possibility of there being infectious molecules other than ...

Seaweed could make junk food healthier

...ody's natural protection of the gut wall, can slow digestion down, and can slow the uptake of nutrients in the body. Moreover, alginate is high in fibre and has been proved to be palatable and safe, and as such is already in widespread use by the food industry as a gelling agent, to reconstitute powdered food...

A frog's life is food for thought

...ts pre-aestivation state, and by the completion of digestion of the first meal the gut was operating on par with that of non-aestivating frogs," she said. "This rate of rectification of gut morphology is virtually unparalleled with the small intestine having increased in mass by 450 percent within just 36 hou...

Study of genomic DNA leads to new advances in cancer diagnostics

...gestion. Non-malignant cells were sensitive to DNA digestion by Alu I while highly malignant cells were resistant. These results suggest that a cell's DNA, or chromatin, is protected during malignancy. This effect was confirmed using three pairs of cell types (normal melanocytes and melanoma cells, normal brea...

However, E.coli is also commonly associated with illnesses caused by eating undercooked beef or drinking contaminated water. Without access to the large collection of bacteria strains from the Gastroenteric Disease Center, it w...
