...especially high blood pressure. By acting as the sole signaling molecule for blood-vessel relaxation, nitric oxide is central to blood- pressure regulation. Such observations have been made in laboratory research. The natural production of nitric oxide in the body can be supported by supplementing the diet with the amino acid l-arginine in combination with antioxidant nutrients and by engaging in a moderate exercise program...
...news: although taking folic acid reduces blood levels of the amino acid homocysteine-- a major risk factor for heart disease and stroke--no matter how much you reduce your homocysteine with folic acid, your risk of dying from stroke or heart disease doesn't change...
...mind that there is no need to publish your answers. Some options are: 1) Number of times swore off psychologically destructive behavior, 2) number of people desired, attained and/or rejected (or, for that matter, the number of people by whom you have been thus treated), 3) number of amino acids consumed daily, 4) number of pants sizes increased, 5) number of times reminded yourself to talk about your significant other’s good qualities...
...superior approach to existing treatments, which simply seek to lower TNK levels. Xencor's approach derives from a process Dahiyat invented in 1997 while a graduate student at Caltech. Instead of using time-consuming methods like trial and error, he asked a computer to figure out what mix of amino acids would make a protein of a particular shape. (Shape is important because a protein's structure determines its function. Just like a flathead screwdriver is appropriate for some jobs and a Philips for others, proteins' different shapes help them effectively attack different disease cells.) The desired shape is easy...
...Caltech colleagues laughed, but off he went to the supercomputer at Caltech's famed Jet Propulsion Laboratory. "I said, here's the shape I want to make, tell us the sequence,'' he recalls. By the end of the day, the computer gave him billions of possible amino acid combinations and recommended the best one. Dahiyat threw that sequence into a small, tunnel-like device called an NMR spectrometer. About a minute later, Dahiyat noticed that the V-shaped protein was indeed falling into place. "I could see it wasn't spaghetti. I said, 'Oh my God, we've got structure...
