Vitamin A is a family of fat-soluble vitamins. Retinal is one of the most active, or usable, forms of vitamin A. It plays an important role in vision, bone growth, reproduction, cell division and differentiation. It maintains the surface linings of eye and respiratory, urinary, and intestinal tracts. Vitamin A may help lymphocytes a type of white blood cell that fights infections, function more effectively. It also may help prevent bacteria and viruses from entering body by maintaining the integrity of skin and mucous membranes.

Vitamin D is a fat-soluble vitamin, which acts like a hormone, regulating the formation of bone and the absorption of calcium and phosphorus from the intestine. It helps to control the movement of calcium between bone and blood. The term vitamin D also refers to metabolites and other analogues of these substances. It plays an important role in the maintenance of organ systems. It regulates the calcium and phosphorus levels in the blood by promoting their absorption from food in the intestines, and by promoting re-absorption of calcium in the kidneys. It promotes bone formation and mineralization and is essential in the development of an intact and strong skeleton.

Vitamin E is a fat-soluble vitamin that acts as an antioxidant. It is an antioxidant that protects body tissue from damage caused by unstable substances called free radicals. Free radicals can harm cells, tissues, and organs. It is also important in the formation of red blood cells and helps the body to use vitamin K. The ability of vitamin E to prevent cancer, heart disease, dementia, liver disease, and stroke are still not known. At lower levels, vitamin E may help protect the heart.

Vitamin K is a fat-soluble vitamin. It is essential for the functioning of several proteins involved in blood clotting. It is a necessary participant in synthesis of several proteins that mediate both coagulation and anticoagulation. The key vitamin K-dependent proteins include coagulation proteins, anticoagulation proteins, bone proteins osteocalcin and matrix-Gla protein, and certain ribosomal proteins.

Thiamin is a water-soluble B vitamin. It occurs in the human body as free thiamin and as various phosphorylated forms: thiamin monophosphate (TMP), thiamin triphosphate (TTP), and thiamin pyrophosphate (TPP), which is also known as thiamin diphosphate.

Riboflavin is a water-soluble B vitamin. It is also known as vitamin B2. In the body, riboflavin is primarily found as an integral component of the coenzymes, flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN). Coenzymes derived from riboflavin are termed flavocoenzymes, and enzymes that use a flavocoenzyme are called flavoproteins.

Niacin is a water-soluble vitamin, which is also known as nicotinic acid or vitamin B3. Nicotinamide is the derivative of niacin and used by the body to form the coenzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP).

Vitamin B12 is a water-soluble vitamin. It is important to good health. It is also called cobalamin. Water-soluble vitamins dissolve in water. After the body uses these vitamins, leftover amounts leave the body through the urine. Vitamin B12 is special, because the body can store it for years in the liver. Due to this, a vitamin B12 deficience is very rare. It is important for metabolism. It helps in the formation of red blood cells and in the maintenance of the central nervous system.

Folate is a water-soluble B vitamin that occurs naturally in food. It helps to produce and maintain new cells. This is especially important during periods of rapid cell division and growth such as infancy and pregnancy. Folate is needed to make DNA and RNA, the building blocks of cells. It also helps prevent changes to DNA that may lead to cancer. Both adults and children need folate to make normal red blood cells and prevent anemia. Folate is also essential for the metabolism of homocysteine, and helps maintain normal levels of this amino acid.

Biotin is a water-soluble vitamin. It is generally classified as a B-complex vitamin. It is required by all organisms but can only be synthesized by bacteria, yeasts, molds, algae, and some plant species. In its physiologically active form biotin is attached at the active site of four important enzymes, known as carboxylases. Each carboxylase catalyzes an essential metabolic reaction.

Pantothenic acid is also known as vitamin B5. It is essential to all forms of life. It is found throughout living cells in the form of coenzyme A (CoA), a vital coenzyme in numerous chemical reactions. Pantothenic acid is a component of coenzyme A (CoA), an essential coenzyme in a variety of reactions that sustain life. CoA is required for chemical reactions that generate energy from food, fat, carbohydrates, and proteins.

Vitamin C is also known as ascorbic acid. It is a water-soluble vitamin. It is required for the synthesis of collagen, an important structural component of blood vessels, tendons, ligaments, and bone. Vitamin C also plays an important role in the synthesis of the neurotransmitter and nor epinephrine. Neurotransmitters are critical to brain function and are known to affect mood. In addition, vitamin C is required for the synthesis of carnitine, a small molecule that is essential for the transport of fat to cellular organelles called mitochondria, for conversion to energy. It is also involved in the metabolism of cholesterol to bile acids, which may have implications for blood cholesterol levels and the incidence of gallstones.

Virtual fluoroscopy system is a medical device called a fluoroscope thats takes an X-ray of a patient and displays it on a viewing screen, much like a TV. It is a navigational system that combines a conventional C-arm fluoroscope with a surgical computer. By harnessing the power of the computer with the fluoroscope, allows the surgeon to see many views of the spine from many different angles simultaneously, all with minimal X-ray exposure.

Vertical needle holder holds low dose rate brach therapy needles in place for loading. It provides stainless steel shielding for loaded needles. The vertical needle holder is also available as a component in the needle loading platform and shield with vertical needle holder system. Needle tips are not in danger of blunting as needles are suspended in the needle holder.

Vinyl electrode is designed to provide excellent pickup with a strong adhesive that is gentle to the skin, while at the same time allowing the skin to breathe.
