A new dinuclear triphenyl-anti-mony(V) derivative with an oxide bridge, [Sb(2)(C(6)H(5))(6)(C(6)H(3)ClNO(2))(2)O], has been synthesized. Each Sb atom is five-coordianted by three C atoms and two O atoms in a distorted trigonal-bipyramidal geometry. Metal centers are bridged by a μ(2)-oxide functionality, and phenyl substituents on Sb atoms are in an staggered arrangement. The Sb-O-Sb bridge dis...

Scutellaria barbata D. Don (S. barbata), a traditional Chinese medicine, is used to treat cancers, inflammation, and urinary diseases. This study aimed to determine any protective effects of S. barbata crude extract (CE-SB) against rat liver tumorigenesis induced by diethylnitrosamine (DENA). Liver malfunction indices in serum were measured by biochemical examination. Hematoxylin and eosin stai...

This work provides a method with application of valid techniques to extract and determinate inorganic species of antimony (Sb) for water. The procedure involves•the simultaneous accumulation of Sb(III) and Sb(V) on passive samplers like Diffusive Gradient in Thin Films (DGT) with iron (Fe) oxide gel, eliminating the risk of speciation changes due to transport and storage;•application of less co...

We predict planar Sb/Bi honeycomb to harbor a two-dimensional (2D) topological crystalline insulator (TCI) phase based on first-principles computations. Although buckled Sb and Bi honeycombs support 2D topological insulator (TI) phases, their structure becomes planar under tensile strain. The planar Sb/Bi honeycomb structure restores the mirror symmetry, and is shown to exhibit non-zero mirror ...

The corrosion inhibition activity of a newly synthesized Schiff base (SB) from 3-acetyl-4-hydroxy-6-methyl-(2H)-pyran-2-one and 2,2'-(ethylenedioxy)diethylamine was investigated on the corrosion of mild steel in 1 M HCl solution using potentiodynamic polarization and electrochemical impedance spectroscopic techniques. Ultraviolet-visible (UV-vis) and Raman spectroscopic techniques were used to ...

The main objective of the present work was to study, for the first time, the effect of naturally-derived compounds Chitosan (CS), Silibinin (SB) and their combination in different doses on the expression level of both p21 and p53 genes in Ehrlich ascites carcinoma (EAC) bearing mice considered as a model for the cancer. The aim was to evaluate the antitumor activity, lipid peroxidation, nitrosa...

AIMS In coronary bifurcations assessment, evaluation of side-branch (SB) ostia by an optical coherence tomography (OCT) pullback performed in the main branch (MB) could speed up lesion evaluation and minimize contrast volume. Dedicated software that reconstructs the cross-sections perpendicular to the SB centreline could improve this assessment. We aimed to validate a new method for assessing t...

BACKGROUND AND AIM The purpose of this analysis was to determine the factors responsible for side branch (SB) ostial stenosis after main vessel stent implantation. METHODS Theoretical and bench-test bifurcation models with different lengths of carina were created. Bench-test experiments with a flexible bifurcation model were performed for the observation of changes in the bifurcation region a...

The molecular mechanism of antimony-resistant Leishmania donovani (Sb(R)LD)-driven up-regulation of IL-10 and multidrug-resistant protein 1 (MDR1) in infected macrophages (Ms) has been investigated. This study showed that both promastigote and amastigote forms of Sb(R)LD, but not the antimony-sensitive form of LD, express a unique glycan with N-acetylgalactosamine as a terminal sugar. Removal o...
