Background: Many in vitro studies suggested that choline incorporation into many types of tumors is related to cell proliferation. Whether in vivo choline incorporation is related also to cell proliferation or not was my question. Therefore, the aim of this pilot study was to investigate the relationship of in vivo [methyl- 14C]-choline incorporation and in vivo [methyl-3H]- thymidine incorpora...

methyl orange is one dye resulted from the textile industry. the aim of this study is to test theadsorption capacity of nickel oxide nanoparticles for removing the methyl orange from aqueoussolution. the parameters studied were the effect of temperature, contact time and initial ph ofsolution. results indicate that the removal efficiency of nickel oxide nanoparticles increases withincreasing co...

Photodegradation of methyl orange was investigated using synthesized TiO2:Mg2+/zeolite as the photocatalyst. The photocatalyst was characterized by X-ray, XRF, FT-IR, and SEM. The photocatalytic activities of TiO2:Mg2+/zeolite samples were evaluated in the degradation of methyl orange under visible light irradiation. The appropriate content of Mg in the composite was obtained as 4.711 wt% with ...

a completely randomized design (crd) with three replications was conducted at greenhouse of urmia university in 2013 to study the effect of different methyl jasmonate concentrations (0, 0.1 and 0.5 mm) on the activity of enzymes polyphenol oxidase, phenylalanine ammonia lyase, catalase, ascorbate peroxidase, guaiacol peroxidase and total protein content in basil. activity of the enzymes and tot...

2- methylsulfonyl - 5- (1-methyl-5-nitro- 2 – imidazolyl ) 1,3,4 - thiadiazole ( 1 ) was prepared by twa independent routes.1) reaction of 1-methyl-2-formyl-5- nitroimidazole (3) with methyl hydrazinecarbodithioate gave the hydrazone 4. reaction of compound 4 with acetic anhydride followed by potassium permanganate oxidation of the intermediate 5 gave the desired compound 1. 2) reaction of thio...
