    Danger of Vitamin B12 Deficiency

    March 14, 2019, Categories  Health/Medical, Biology/Biotechnology

    Rice University researchers found vitamin B12 promotes survival during infection by improving mitochondrial health. The expression of a fluorescent protein (top left) reflects buildup of a toxic metabolic product, propionate, in mitochondria on diets low in B12, as compared (bottom left) to those receiving sufficient B12. Mitochondrially targeted fluorescent protein (center) reveals fragmentation of mitochondria when B12 is low, and dead worms stained with fluorescent dye (bottom right) demonstrate the decreased survival rate of worms infected by the pathogen Pseudomonas aeruginosa.

    Catching some midday shut-eye linked to similar drops in blood pressure seen with other lifestyle changes, some medications. It seems that napping may do more than just reboot our energy level and improve our mood. New research being presented at the American College of Cardiology’s 68th Annual Scientific Session found that people who took advantage of a midday snooze were more likely to have a noticeable drop in blood pressure compared with those who didn’t nap.

    “Midday sleep appears to lower blood pressure levels at the same magnitude as other lifestyle changes...

    Special diet with compounds contained in green tea and carrots restored working memory. A diet containing compounds found in green tea and carrots reversed Alzheimer’s-like symptoms in mice genetically programmed to develop the disease, USC researchers say.

    Researchers emphasize that the study, recently published in the Journal of Biological Chemistry, was in mice, and many mouse discoveries never translate into human treatments. Nevertheless, the findings lend credence to the idea that certain readily available, plant-based supplements might offer protection against dementia in humans.

    “You don’t have to wait 10 to 12 years for a designer drug to make it to market; you can make these dietary changes today,” said senior author Terrence Town, a ...
