High yield photolytic reduction of a series of thiaphosphoranes Z p SR to give Z p H with UV-light-induced tri-n-butyltin hydride through phosphoranyl radical Z p is described. This reaction is inhibited by a-methylstyrene and initiated by a radical initiator such as azobisisobutyronitrile

The aim of the present study was to evaluate the effect of troxerutin (TXN) on Nickel (Ni) toxicity by using rats and in vitro model. Ni toxicity induced in male albino wistar rats (20 mg/kg body weight (b.w) was administered orally for 20 days). TXN was administered orally (100 mg/kg (b.w) for 20 days with administration of Ni. The toxic effect of Ni and the action of TXN was measure by determ...

Secondary organic aerosol (SOA), particulate matter composed of compounds formed from the atmospheric transformation of organic species, accounts for a substantial fraction of tropospheric aerosol. The formation of lowvolatility (semivolatile and possibly nonvolatile) compounds that make up SOA is governed by a complex series of reactions of a large number of organic species, so the experimenta...

in order to optimization of protein hydrolysis condition (including enzyme to substrate ratio (e/s), temperature and time) for achieving the highest antioxidant activity, the green tiger prawn (p. semisulcatus) mince was tested via commercial protease (alcalase® 2.4l) based on the response surface designed method in 18 treatments and then dried to obtain powder in freeze dryer. the antioxidant ...

Background & Aim: Medicinal plants can be a good replacement for common cancer treatment including chemotherapy, radiation therapy and surgery because they don’t have many side effects. The aim of this study was to investigate the effect of temperature on the free radical scavenging in the presence of medicinal plants. Experimental: For determination of free radical scavenging activity was use...

The oxidation of caffeine with persulfate and hydroxyl radicals in aqueous solution has been studied by EPR spectroscopy and HPLC analysis. In both cases the formation of 1,3,7-trimethyluric acid is observed as the main final product. A C8]OH radical adduct is postulated as the intermediate after reaction with OH~, and leads to the final product after further oxidation. This radical is too shor...
