Flexible tail of the prion protein poisons brain cells

Prion proteins are the infectious pathogens that cause Mad Cow Disease and Creutzfeldt-Jakob disease. They occur when a normal prion protein becomes deformed and clumped. The naturally occurring prion protein is harmless and can be found in most organisms. In humans, it is found in our brain cell membrane. By contrast, the abnormally deformed prion protein is poisonous for the brain cells. Scientists have now discovered that the prion protein has a kind of switch that controls its toxicity.

I'm nearly idaintcel to you. I'm 15, 5'4 , and 140.Honestly going vegetarian doesn't guarantee weight-loss unless you really pay attention to your calorie and nutrient intake. Vegetarians tend to actually GAIN weight when they first start out because they resort to eating processed foods and carbs. Potato chips, mashed potatoes, white bread, cookies, soda, and most candies are all vegetarian.When I went vegetarian I gained about 10 pounds, then after I started paying attention to the foods I ate I lost about 15. In order to lose weight as a vegetarian, you have to replace your meats properly. When I went vegetarian at first I just eliminated my meats. When my mom made steak, mashed potatoes and corn for dinner, I just ate potatoes and corn.Morning Star and Boca products are good for starters. They are basically fake meat, made from vegetables and soy products. But I wouldn't eat these excessively, since they are loaded with processed ingredients. You really, really have to make sure you're eating a variety of vegetables and fruits. Before it wasn't AS important since you obtain many nutrients from meat. But now you MUST make sure you aim for at least 6-8 fruits/vegetables a day.As long as you're conscious about what you're eating and don't resort to cupcakes and potato chips, you definitely could lose weight on a healthy vegetarian diet.

I just want to say thanks so much for all of your exclelent work with the French lessons on About.com. I've been trying to teach myself that language over the past few weeks and your insight on everything from the broad to the detailed issues in learning a new language have been invaluable to me. I'm so glad I found one place where I can learn everything I need! Keep up the great work!
