Green tea contains folate and epigallocatechin gallate (EGCg), which is suggested to be an antifolate. In this study, we examined whether green tea was a good source of folate in a folate depletion/repletion rat model. Rats fed a folate deficient diet for 4 weeks were supplied with folate for 7 days, and then folate repletion effects were evaluated in terms of increase in total folate level in ...

A magnetic chitosan-polypyrrole-magnetite (Cs-PPy-Fe3O4) nanocomposite is prepared in a simple one-step method via in situ chemical polymerization of pyrrole using anhydrous FeCl3 as an oxidant in the presence of Cs. Magnetic Fe3O4 nanoparticles of size in the range of 10-20 nm are successfully introduced into the Cs-PPy matrix. Adsorption of an anionic dye (acid green 25, AG) from aqueous solu...

a field experiment was conducted at research station of zabol university in 2012. the experiment carried out as split plot on basis of a randomized complete block design with three replications. the main and sub factors included tillage systems (no, reduced, and conventional tillage) and planting ratios of intercropping (pure culture of roselle, pure culture of green gram, 25% roselle + 75% gre...

Bile acid binding capacity has been related to the cholesterol-lowering potential of foods and food fractions. Lowered recirculation of bile acids results in utilization of cholesterol to synthesize bile acid and reduced fat absorption. Secondary bile acids have been associated with increased risk of cancer. Bile acid binding potential has been related to lowering the risk of heart disease and ...

N,N-diethylethanaminium-2-(sulfooxy) ethyl sulfate was synthesized and used as  an efficient, green, and recyclable catalyst and solvent for the nitration of aromatic compounds by nitric acid at 80oC

Human color-vision discriminates middlefrom long-wavelength spectral light 13 as a result of photopigment opsin genes found on the q-arm of the X-chromosome at 14 location Xq28. These so called ‘green’ and ‘red’ opsin gene sequences are 98% 15 homologous, producing middle-wavelength sensitive and long-wavelength sensitive 16 photopigment opsin gene sequences which differ by only seven locations...

Phenolic acids are thought to be beneficial for human health and responsible for vegetables' health-promoting properties. Free, conjugated, and bound phenolic acids of seven commonly consumed vegetables, including kidney bean, cow pea, snow pea, hyacinth bean, green soy bean, soybean sprouts and daylily, from the regions of Beijing, Hangzhou, and Guangzhou, were identified and quantified by ult...

Nowadays, soybeans are commercialized in a wide variety of colors and tones. Moreover, some pigmented seeds are being commercialized as soybeans while, on other occasions, these seeds are labeled as mung beans, azuki beans or soybean frijoles generating confusion on their identity. In this work, CE has been applied for the first time for the characterization and differentiation of different pig...

In frog retina there are special rod photoreceptor cells ('green rods') with physiological properties similar to those of typical vertebrate rods ('red rods'). A cDNA fragment encoding the putative green rod visual pigment was isolated from a retinal cDNA library of the bullfrog, Rana catesbeiana. Its deduced amino acid sequence has more than 65% identity with those of blue-sensitive cone pigme...

in this work, so3h-functionalizedphthalimide (sfp) as a so3h-containing solid acid is prepared by the reaction of phthalimide with chlorosulfonic acid, and characterized by ft-ir, 1h and 13c nmr, mass, tg, dtg, xrd and sem. then, it is utilized as a highly efficient, heterogeneous and green catalyst for the one-pot multi-component condensation of dimedone with arylaldehydes, β-ketoesters and am...
