Science of Sport: Branched Chain Amino Acids and Exercise
Introduction: Amino Acids are the building blocks for skeletal muscle as well as digestive enzymes, hormones, antibodies and other body proteins necessary for optimal functioning. Of the 20 amino acids in the body, there are two types: essential and non-essential. There are eight essential amino acids including -- leucine, isoleucine, lysine, methionine, phenylalanine, theonine, tryptophan, and valine. The term essential is used because the body cannot synthesize these amino acids, making it necessary to obtain them from the diet. The twelve non-essential amino acids are equally important, but can be synthesized in the body at a rate that equals demand so dietary intake is not as crucial. Complete proteins include all of the essential amino acids, and are considered higher quality proteins.
Then perhaps annoyance is the father of invention
HOW do you get rich? You can't count on your aunt Zeddie dying and leaving you a fortune. You can't even count on your family having a fortune to leave you. You can control your investments a little better. If your shares in Annoying Ringtones Inc. take off, you'll get rich AND look shrewd. But if you want more control and more risk, you can make a fortune with sweat equity. Yes, with hard work, the right idea and smart execution, you can start an empire, or at least a cute little Web site to sell to Google. Like writers, entrepreneurs are often asked, "Where do you get your ideas?" As a writer, I get ideas via stress, neurosis and subway rides. That doesn't work as well for startups, as I found out when I recently had to think up business ideas for a class.
Study: Fat Loss Might Stimulate Anti-Tumor Defense
(AP) WASHINGTON Fatty tissue may decrease the body's ability to kill off cancer, says a study that found making mice leaner -- through exercise or surgery -- seemed to help them fight skin tumors.Scientists have long known that people who are overweight are at increased risk of certain types of cancer. The question is why, and whether slimming down will lower that risk or do any good after a tumor forms.Rutgers University scientists took a closer look at that question using mice engineered to get skin cancer, and reported Monday that fat cells may secrete substances that short-circuit one of the body's main anti-tumor defenses.When cells become genetically damaged -- such as the DNA damage caused by the sun's ultraviolet rays -- they're supposed to self-destruct. It's a process called apoptosis that helps clear out bad cells before they can grow into tumors.The Rutgers' team put running wheels in the cages of some laboratory mice.
