...conducted an elegant experiment on mice with a uniquely regulated agouti gene - a gene that gives mice yellow coats and a propensity for obesity and diabetes when expressed continuously. Jirtle's team fed one group of pregnant agouti mice a diet rich in B vitamins (folic acid and vitamin B12). Another group of genetically identical pregnant agouti mice got no such prenatal nutrition...
Strict veganism prohibits the use of animal product, even if it isn't food, but like any lifestyle choice that ends in "-ism," there are plenty of people who cheat. The vitamin B12 is found almost entirely in animal products, so many vegans eat fortified food or take a vitamin to get the right amount. And while American vegetarianism has broken free of its philosophical and religious roots, becoming an accepted health choice - many restaurants offer vegetarian options and most dinner party planners now ask "is anyone vegetarian?" before planning the menu - veganism is still tied to the animal-rights...
...Power Horse advertises itself as healthy, stating that it “releases the energy dormant in us.” It also contains vitamins B12, B2 and B6. The other unpronounceable ingredients, according to the website, are quite the opposites of assumed carcinogens and actually detoxify the body. That energy should stay dormant. Caffeine, the active ingredient, is an addictive drug. From my experience, anything that causes my body to shake can’t be healthy...
...that was made public on Valentine's Day looks like an extraterrestrial bouquet, a blossom from another galaxy. But it is a revelation from a skirmish in deepest inner space, one with huge potential promise in the war against AIDS. The twisting green "stems" are a rare antibody called b12; the red "florets" are a surface protein of the HIV virus; and the yellow area where they meet is the virus' point of vulnerability, where the b12 antibody latches on to start neutralizing the deadly entity that causes AIDS. The 3-D X-ray crystallographic image, released as part...
...While b12 is a rare antibody, occuring in only a very few individuals, what it does to this particularly vulnerable protein in the HIV virus has now been documented in great detail in the new study. The b12 antibody thus provides a key to scientists: its behavior will give them a precise roadmap on which to develop potential vaccines that would replicate b12's actions. One other advantage of b12 and its target protein (which is called HIV gp120): while the HIV virus is known to mutate over and over again, the HIV gp120 protein is stable throughout the existing...
