A novel rod-shape BaNiSn-Graphene oxide decorated TiO2 composite (BaNiSn-GT) has been synthesized using a simple ultrasonic method to enhance the visible-light-driven H2 evolution with cationic scavengers. The unique structure between interfaces of and provides graphene contact excellent electron transfer for activity. BaNiSn-GT ternary photocatalyst exhibits relatively high photocatalytic acti...

The inhibition by oxybarbiturates of diphosphopyridine nucleotide (DPN)-linked oxidations in mitochondria was observed some time ago (l-4). Their effect on the associated phosphorylation was subsequently reported (5,6), but it is now apparent that oxybarbiturates do not uncouple oxidative phosphorylation (7) nor do they inhibit dinitrophenol-activated adenosine triphosphatase (7). Amytal inhibi...

Thenoyltrifluoroacetone inhibits succinate-cytochrome c reductase activity of resolved succinate*cytochrome c reductase complex. Dixon plots of [succinate-cytochrome c reductase activity]-’ or [succinateubiquinone reductase activity]-’ versus concentration of inhibitor are consistent with there being a single site of inhibition by thenoyltrifluoroacetone in resolved reductase complex. This agre...

In this research, a glassy carbon electrode was coated with a thin layer of multi-walled carbon nanotubes in the presence of the surfactant and subsequently was electro-polymerized with Poly-L-arginine (P-L-Arg). The prepared electrode was used as an effective sensor for the quantitative detection of Rutin (Ru). The fabricated electrode exhibited good electrochemical performance with low electr...

Free radicals play an important role in pathological processes such as aging and developing cancer; hence, natural products inhibit free radical production, and can play an important role in preventing diseases. We aimed to evaluate the scavenging activity of free radicals, reducing power, inhibition of lipid peroxidation and malondialdehyde (MDA) formation, and the antioxidant composition of r...

Background: Hydatid cyst is the larval stage of the tape worm parasite, Echinococcus granulosus. Human is infected by ingestion of parasite ova excreted in dog feces. The anticancer activity of different antigens of hydatid cyst has been reported in the previous works. In this research, the role of immune system in induction of this anticancer activity has been investigated.Materials and Method...

Energy transfer inhibition by HgCl2 has been demonstrated to be selective for certain System I partial reactions. On the basis of different HgCl2 effects on the System I reactions, reduced 2,6-dichlorophenolindophenol --> methylviologen, diaminodurene --> methylviologen and N-phenazine methosulfate cyclic, two sites of energy conservation associated with System I are proposed. Furthermore, thes...
