B vitamins or Vitamin B-Complex is a class of vitamins responsible for various processes in the body. Vitamin B complex is water-soluble and is eliminated through the urine. The B vitamins are vast with 12 classifications of vitamin B complex. These include:
Alcohol Alcohol passes directly from the digestive tract into the blood vessels. In minutes, the blood transports the alcohol to all parts of the body, including the brain. Alcohol affects the brain’s neurons in several ways. It alters their membranes as well as their ion channels, enzymes, and receptors. Alcohol also binds directly to the receptors for acetylcholine, serotonin, GABA, and the NMDA receptors for glutamate.
By Marcia Jedd / January - Febuary 2005 The strong hands of Thomas Stout, a certified Structural Integration practitioner, bore down on my lower right leg and began pressing in, at an angle, around my ankle. The pain was almost unbearable. Involuntarily, I yelled out. Stout eased up slightly. “Meet me on the edge of pain,” he instructed gently.
Moreover, the process of natural selection may be expected later on to lead to the survival of a species or strain that synthesizes somewhat less than the optimum amount of an autotrophic vital substance rather than of the species or strain that synthesizes the optimum amount. To synthesize the optimum amount requires about twice as much biological machinery as to synthesize half the optimum amount. As suggested in Fig. 1, the evolutionary disadvantage of synthesizing a less than optimum amount of the vital substance may be small, and may be outweighed by the advantage of requiring a smaller amount of biological machinery. Evidence from the study of microorganisms is discussed in the following paragraphs. Many mutant microorganisms are known to require, as a supplement to the medium in which they are grown, a substance that is synthesized by the corresponding wild-type organism (the normal strain).
