Vitamin D
Vitamin DAuthor: Vitamins AustraliaIntroductionOne of the fat-soluble vitamins, vitamin D constitutes two major forms which are vitamin D2 or ergocalciferol and vitamin D3 or cholecalciferol. Vitamin D2 is synthesised by plants whilst vitamin D3 is synthesised by the body. Vitamin D is naturally present in a number of food sources and dietary supplements, and is also manufactured with the aid of sun exposure. It is produced within the body when ultraviolet-B or UVB rays from sunlight reaches the skin. The liver and the kidney eventually help to convert vitamin D to an active hormone form.Functions of Vitamin DVitamin D plays several key roles in the maintenance of organ systems. For example:* Vitamin D helps regulate calcium concentrations in the blood. Since it works more like a hormone, its active form, calcitriol acts with the parathyroid hormone or PTH. If the calcium level is low, this would trigger the secretion of PTH, which would stimulate the conversion of vitamin D to calcitriol. Calcitriol would then act to increase calcium absorption in the intestines, calcium resorption in the kidneys and stimulate calcium release from the bones. * Vitamin D helps maintain blood phosphorus levels. Low levels of vitamin D can result to an overactive parathyroid gland. Also with inadequate phosphorus in the body, bones cannot undergo normal mineralisation. * It is also said that vitamin D benefits the immune system since the T-cells or immune cells have receptors for vitamin D.

Sexy Las Vegas ShowsSexy Las Vegas ShowsAuthor: Louis MoonIf you've never been to Vegas or experienced one of the many Vegas shows that are available to behold, let me be the first to tell you: they are not created equal. People will choose to see shows for many different reasons and there is no right or wrong reason to see any Vegas show unless you are simply determined to hate it from the beginning. Even then you might find yourself to be either mildly or wildly surprised.I would be remiss if I didn't take the time to mention some of the wonderfully sexy shows that are prominent in Vegas at the moment. There are quite a few and will appeal to audiences on different levels and for different reasons, well some of them will at any rate while most of them offer universal appeal to certain members of the audience it is important to remember the statement I made earlier, not all shows are created equally and it doesn't really matter how beautifully endowed the members of the cast are if the show has no wit, humor, drama, or interesting points about it.Les Foiles Bergere is one of the best examples of a classic Vegas style show or at least my interpretation of what a Vegas style show should be. This show literally sizzles with its sex appeal and is a great show to kick off your stay in Vegas. |
