The increasing worldwide incidence of obesity and the limitations of current treatments raise the need for finding novel therapeutic approaches to treat this disease. The purpose of the current study was first to investigate the effects of tungstate on body weight and insulin sensitivity in a rat model of diet-induced obesity. Second, we aimed to gain insight into the molecular mechanisms under...

Tungstate was orally administered to 7.5-week-old male Zucker diabetic fatty (ZDF) rats that already showed moderate hyperglycemia (180 +/- 16 mg/dl). The animals became normoglycemic for approximately 10 days. Then, glycemia started to rise again, although it did not reach the initial values until day 24, when levels stabilized at approximately 200 mg/dl for the duration of the experiment. Unt...

A low protein diet (1, 2) removed about three-fourths of the xanthine oxidase from the entire rat (3), while a purified diet containing tungstate reduced the tissue xanthine oxidase to a level at which it could not, be detected manometrically (4) ; neither of these dietary procedures had any effect on the uric acid or allantoin excretion by this species. Chicks fed a tungstate-containing diet e...

Nanoparticles of ytterbium tungstate prepared through the direct addition of an Yb3+ solution to a tungstate solution, were computed through Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS). Further the supercapacitive characteristics of the nanoparticles, as a potential material for constructing electrodes, were eval...

Soybean (Glycine max [L.] Merr.) seeds were imbibed and germinated with or without NO(3) (-), tungstate, and norflurazon (San 9789). Norflurazon is a herbicide which causes photobleaching of chlorophyll by inhibiting carotenoid synthesis and which impairs normal chloroplast development. After 3 days in the dark, seedlings were placed in white light to induce extractable nitrate reductase activi...

Pyrobaculum aerophilum, a hyperthermophilic archaeon, can respire either with low amounts of oxygen or anaerobically with nitrate as the electron acceptor. Under anaerobic growth conditions, nitrate is reduced via the denitrification pathway to molecular nitrogen. This study demonstrates that P. aerophilum requires the metal oxyanion WO42- for its anaerobic growth on yeast extract, peptone, and...

In this work, we present a new photochromic tungstate based glass which have both absorption coefficient and refractive index modified under laser exposure. The photosensitive effect is superficial under ultraviolet (UV) irradiation but occurs in the entire volume of the glass under visible irradiation. The effect can be obtained in any specific point inside the volume using an infrared femtose...

The interaction of tungsten (VI) oxide and calcium tungstate with a molten eutectic mixture calcium-sodium chlorides in the temperature range from 600 to 800 °С was investigated by methods isothermal saturation, mass spectrometry inductively coupled plasma (ICP–MS) X-ray phase analysis. It noted that solubility both trioxide depends large extent on temperature. Thus, 700 °C, equilibrium concent...
