.... Vitamins do not contain calories and do not supply energy. In other words, they do not contribute to weight gain. They are, however, most important as constituents of enzymes, those organic catalysts which enable biological processes to take place. It is totally impossible to imagine life without vitamins and enzymes. Through enzymes, vitamins stimulate metabolic processes, converting food to energy and accelerating biological functions. They are truly vital or “life-giving” as the first part of their name implies. They create blood, skin and bone, release energy, and enable rep .....

.... on the surface of T-cells and microphages, they are used to "talk" to, arouse, and attract cells. There are two variants of chemokines, alpha and beta chemokines. Among these there are many different chemokines from CCR5, CCR3, CXCR4, etc… Now AIDS needs the CD4 molecule and the CCR5 protein to be present on a T-cell to successfully infect the cell. It needs the CD4 molecule to latch on to the cell. Once this is accomplished it needs the CCR5 protein to be able to get inside of the cell in order to infect it. Both of these two factors are essential in order for AIDS to infect a perso .....

.... part of the fetus (Leese, Conaghan, Martin, and Hardy, April 1993). As the blastomeres continue to divide, a solid ball of cells develops to form the morula (Fig. 1). The accumulation of fluid inside the morula, transforms it into a hollow sphere called a blastula, which implants itself into the inner lining of the uterus, the endometrium (Fig. 1). The inner mass of the blastula will produce the embryo, while the outer layer of cells will form the trophoblast, which eventually will provide nourishment to the ovum (Pritchard, MacDonald, and Gant, 1985). Figure 1:Implantation process and de .....

.... United States in the mid-1980s, more than one-fifth of all deaths were caused by cancer; only the cardiovascular diseases accounted for a higher percentage.

.... adolescents, use black market steroids (Schrof, 54). Anabolic steroids are synthetic compounds that resemble the natural male sex hormone testosterone. Male hormones have two different effects in the body. Hormones have an anabolic effect, which stimulates growth, and they have an androgenic effect, which increases male sexual characteristics. Anabolic steroids are constructed synthetically to maximize the anabolic (growth) effect and minimize the androgenic (male characteristic) effect. Steroids are molecules that occur naturally in the body and are carried in the bloodstream and act a .....
