Pt Nanoparticles Confined in a 3D Porous FeNC Matrix as Efficient Catalysts for Rechargeable Li-CO/O Batteries.

The cathodic product LiCO, due to its high decomposition potential, has hindered the practical application of rechargeable Li-CO/O batteries. To overcome this bottleneck, a Pt/FeNC cathodic catalyst is fabricated by dispersing Pt nanoparticles (NPs) with a uniform size of 2.4 nm and 8.

Fe-MOF-Derived Efficient ORR/OER Bifunctional Electrocatalyst for Rechargeable Zinc-Air Batteries.

The construction of an efficient oxygen reduction reaction and oxygen evolution reaction (ORR/OER) bifunctional electrocatalyst is of great significance but still remains a giant challenge for high-performance metal-air batteries. In this study, uniform FeS/FeC nanoparticles embedded in a porous N,S-dual doped carbon honeycomb-like composite ( FeS/FeC@NS-C-900) have been conveniently fabricated by pyrolysis of a single-crystal , which has a low potential gap Δ of ca. 0.

A dinuclear cobalt cluster as electrocatalyst for oxygen reduction reaction.

Dinuclear metal clusters as metalloenzymes execute efficient catalytic activities in biological systems. Enlightened by this, a dinuclear {Co } cluster was selected to survey its ORR (Oxygen Reduction Reaction) catalytic activities. The crystalline {Co } possesses defined structure and potential catalytic active centers of {CoNO} sites, which was identified by X-ray single crystal diffraction, Raman and XPS.

Lutein protects against β-amyloid peptide-induced oxidative stress in cerebrovascular endothelial cells through modulation of Nrf-2 and NF-κb.

In the present study, we determined the protective role of lutein against Aβ peptide-induced oxidative stress and apoptosis in bEND.3 cells. Cell viability was determined through MTT assay.

Pu-erh tea powder preventive effects on cisplatin-induced liver oxidative damage in Wistar rats.

Background: Chemotherapy is one of the major means for control of malignancies, with cisplatin (CDDP) as one of the main agents, widely used for the treatment of various malignant solid tumors. However, prevention of hepatotoxicity from cisplatin is one of the urgent issues in cancer chemotherapy. In this study, we aimed to investigate the effects of pu-erh tea on hepatotoxicity through body weight and tissue antioxidant parameters like, liver coefficient, serum alanine aminotransferase (ALT), serum aspartate aminotransferase (AST), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), malondialdehyde(MDA) and glutathione (GSH) levels, and light microscopic evaluation by histological findings.

[Plaster combined with splint for the treatment of gartland type III humeral supracondylar fractures in children].

Objective: To study clinical effects of plaster combined with splint for the treatment of Gartland type 1I humeral fractures.

Methods: From March 2002 to May 2006, 24 children with humeral supracondylar fractures of Gartland type ill were reviewed. Among the patients, 14 patients were male and 10 patients were female, ranging in age from 4 to 12 years, averaged 6.

Dichlorido{[2-(diphenyl-phosphino)phenyl-imino-meth-yl]ferrocene-κN,P}platinum(II) dichloro-methane hemisolvate.

In the title compound, [FePt(C(5)H(5))(C(24)H(19)NP)Cl(2)]·0.5CH(2)Cl(2), the Pt(II) atom adopts a distorted square-planar geometry defined by one P atom and one N atom from the bidentate [2-(diphenyl-phosphino)phenyl-imino-meth-yl]ferro-cene ligand and two Cl atoms. Two disordered dichloro-methane solvent mol-ecules are each 0.

Repeated oral treatment with polysaccharide sulfate reduces insulin resistance and dyslipidemia in diabetic dyslipidemic rat model.

Polysaccharide sulfate (PSS) is a new type of antiatherosclerotic medicine for its effects of anticoagulation, anti-thrombosis and modulation of dyslipidemia. However, it is still uncertain whether PSS could modulate the diabetic dyslipidemia or not. Here, the rat model of diabetic dyslipidemia was developed and the effects of PSS on glucose and lipid levels were investigated in this animal model.
