the nutritive value of pistachio epicarp (pe) was evaluated by in situ and in vitro techniques. chemical analysis indicated that pe was high in crude protein (11.30%) and low in neutral detergent fiber (26.20%). total phenols, total tannins, condensed tannins and hydrolysable tannins contents in pe were 8.29%, 4.48%, 0.49% and 3.79%, respectively. ruminal dry matter and crude protein degradatio...

nanomaterials (nms) are widely used in health and biomedical applications, however, only a few studies investigate their toxic effects.  the present report signifies a contribution to the study of the toxic effects of silver nanoparticles (ag nps)  on   e. coli cells, which is a model organism of anthropogenic pollution. the toxicity of nanoparticles depends on their  chemical and surface prope...

objective: to study the in vitro color changes of three dental resin veneering materials when immersed in tea, coffee and tamarind extracts. materials and methods: the color changes of heat polymerized tooth colored acrylic resin (stellondetrey, b, f14, dpi dental products of india ltd, mumbai), auto polymerized tooth colored acrylic resin (dpi, b, qv5, dpi dental products of india ltd, mumbai)...

introduction this study was intended to evaluate the nutritional value, phenolic compounds and digestibility coefficients of barberry leaves. berberis vulgaris is one of the major crops in the province. the province has more than 70 percent and 95 percent of the total area under cultivation of barberry. waste and foliage of barberry harvest traditionally used to feed livestock tannin concentrat...

A tannin isolated from Paullinia pinnata Linn., and tannic acid, have cardiotonic actions on the isolated perfused frog heart. Paullinia tannin is more firmly "fixed" than tannic acid. Tannin solutions contain peroxide, but the cardiotonic action is not dependent on this, since drugs believed to prevent peroxide formation, and sodium pyruvate which destroys peroxides, do not prevent the cardiot...

  Tannins are plant-derived polyphenolic compounds that are widely found in foods, particularly in fruits and beverages. These materials are water-soluble and able to precipitate proteins from aqueous solutions. It had been shown that feeding some animals such as rat and mouse with tannins mimicks the effects of isoproterenol on salivary glands. Tannins stimulate β-receptors by some indirect me...
