The results showed that decomposition products 2 4 are orthovanadate [H2VO4]− (V1) and metavanadate species like [H2V2O7] − (V2), [V4O12] − (V4) 5 and [V5O15] − (V5) for both compounds. The calculated half-life times of the decomposition reaction were 9 and 11 h for NaDeca and MetfDeca, respectively, at 1 mM concentration. The hydrolysis products that presented the highest rate constants were V1 and V4 for both compounds. -

Vanadium in Biosphere and Its Role in Biological Processes
Biological Trace Element Research https://doi.org/10.1007/s12011-018-1289-y Vanadium in Biosphere and Its Role in Biological Processes Deepika Tripathi1 & Veena Mani1 & Ravi Prakash Pal1 Received: 9 July 2017 /Accepted: 26 February 2018 # Springer Science+Business Media, LLC, part of Springer Nature 2018 Abstract Ultra-trace elements or occasionally beneficial elements (OBE) are the new categories of minerals including vanadium (V). The importance of V is attributed due to its multifaceted biological roles, i.e., glucose and lipid metabolism as an insulin-mimetic, antilipemic and a potent stress alleviating agent in diabetes when vanadium is administered at lower doses. It competes with iron for transferrin (binding site for transportation) and with lactoferrin as it is secreted in milk also. The intracellular enzyme protein tyrosine phosphatase, causing the dephosphorylation at beta subunit of the insulin receptor, is inhibited by vanadium, thus facilitating the uptake of glucose inside the cell but only in the presence of insulin. Vanadium could be useful as a potential immune-stimulating agent and also as an antiinflammatory therapeutic metallodrug targeting various diseases. Physiological state and dose of vanadium compounds hold importance in causing toxicity also. Research has been carried out mostly on laboratory animals but evidence for vanadium importance as a therapeutic agent are available in humans and large animals also. This review examines the potential biochemical and molecular role, possible kinetics and distribution, essentiality, immunity, and toxicity- related study of vanadium in a biological system. Keywords Metabolic role . Insulin-mimetic . Biological function . Vanadium Introduction essential elements^ which include aluminum (Al), arsenic (As), cobalt (Co), chromium (Cr), fluorine (F), molybdenum Minerals are inorganic elements, without carbon, found in (Mo), nickel (Ni), silicon (Si), tin (Sn), and vanadium (V) [4]. -
Sports Nutrition: a Review of Selected Nutritional Supplements for Bodybuilders and Strength Athletes
Sports Nutrition: A Review of Selected Nutritional Supplements For Bodybuilders and Strength Athletes Gregory S. Kelly, N.D. Abstract Because there is widespread belief among athletes that special nutritional practices will enhance their achievements in competition, the use of supplements has become common. Accompanying the growth in supplementation by athletes has been a corresponding increase in exaggerated claims or misleading information. This article reviews several supplements currently popular among bodybuilders and other strength athletes in order to clarify which products can be expected to produce results. Included in the discussion are creatine monohydrate, beta-hydroxy beta-methylbutyrate, whey protein, phosphatidylserine, and selected amino acids and minerals. (Alt Med Rev 1997; 2(3):184-201) Introduction The increased focus on fitness and subsequent research in the exercise field has ex- panded the role of nutrition as it relates to sports performance. Because there is widespread belief among athletes that special nutritional practices will enhance their achievements in com- petition, the use of supplements has become common. Although some of the supplements have proven benefits, historically a great deal of the information on products is either misleading or exaggerated. This is perhaps best witnessed in the products marketed to bodybuilders and other athletes concerned with size, strength, and body composition. This article reviews some of the supplements currently promoted in this market in an effort to determine which contribute to maximizing results. Included in the review are creatine monohydrate, beta-hydroxy beta- methylbutyrate (HMB), whey protein, phosphatidylserine, and selected amino acids and minerals. Creatine Monohydrate Creatine monohydrate has become one of the most popular supplements in the history of bodybuilding. -

Vanadyl Sulphate EINECS No. 248-652-7; CAS No
Vanadyl sulphate EINECS No. 248-652-7; CAS No. 27774-13-6 The purpose of the Pre-SIEF is for REACH Pre-Registrants to agree upon 'sameness' of substance. Pre-registrants that agree upon the sameness of substance will then pass into the Substance Information Exchange Forum (SIEF) for that substance, where the data-sharing discussion begins and is coordinated by the SIEF Facilitator. All pre-registrants for vanadyl sulphate have received an e-mail to participate in the ‘Substance Sameness’ discussion. Your response to that survey is your participation in the Pre-SIEF ‘sameness’ discussion. If you would like to receive the ‘Substance Sameness’ survey, please contact the Vanadium Consortium. The typical composition for this substance can be checked below.

Taurine Depletion and Schwann Cell Dysfunction in Diabetic Neuropathy

Abstract It is estimated that 2.6 million people in the UK suffer from diabetes, 50% of whom suffer from diabetic neuropathy. Patients with diabetes have low levels of platelet and plasma taurine and in animal models taurine supplementation ameliorates neuropathic symptoms. The mechanisms behind taurine depletion and taurine supplementation are not well understood. Schwann cells are highly vulnerable to hyperglycaemia-induced stress which plays a key role in the pathogenesis of diabetic neuropathy, however, the mechanisms behind these effects are not well understood. In these studies I have elucidated the effect of hyperglycaemia on taurine transport in isolated human Schwann cells and the mechanisms behind the beneficial effects of taurine supplementation. I demonstrated that high glucose reduces TauT expression in a dose-dependent manner and that high glucose inhibited the pro-oxidant increase in TauT expression and taurine uptake. -

Vanadium/ Vanadyl Sulfate
Alternative Medicine Review Volume 14, Number 2 2009 Monograph 23 V 24 Vanadium/ Vanadium Cr Vanadyl Sulfate Chromium 41 42 Nb Mo Niobium Molybdenum Introduction The chemical element vanadium was first discovered by Spanish-born Mexican mineralogist, Andrés Manuel del Río, in 1801. He originally named the element “panchromium” because of the spectrum of colors associated with various oxides of the metal, but changed the name to “erythronium,” because most of the mineral salts turned red upon heating. Later, del Rio was convinced by fellow scientists that he had really found impure chromium and not a new element. To his regret, that same element was “rediscovered” 30 years later by Swedish chemist, Nils Gabriel Sefstrom, who named it vanadium, after the Nordic goddess of beauty, Vanadis (Freyja).1 Nutritionally, vanadium is thought to be a cofactor in various enzymatic reactions. Data from animal and human studies suggest vanadium mimics the action of insulin.2 Consequently, it may serve a beneficial role in promot- ing healthy glucose metabolism in individuals with diabetes or dysglycemia. Dietary sources for vanadium include mushrooms, shellfish, black pepper, parsley, dill seed, and grains. Biochemistry Vanadium is considered an essential nutrient in some animals.3 For instance, vanadium is essential in the diets of chickens; a deficiency has an adverse affect on bones, feathers, and blood. In humans, classification of vanadium as an “essential nutrient” is still a topic of debate among various research groups.3 Some consider vanadium to be an ultra- trace element, requiring dietary intake of only 20 mcg per day.4 Certain mushrooms species, such as Amanita muscaria, contain amavadine, (S,S)-2,20-(hydroxyimino) di- propionic acid (V[hida]2), a natural, vanadium-containing compound thought to act as a mediator in the oxidation of thiol compounds with carboxylic or ester groups, such as cysteine and glutathione.3 Various forms of vanadium are used in foods or supplements, or found in drinking water.
