Objective: The present investigation has been focused on the detection of antibacterial activity of methanolic extract by disc diffusion method and the quantitative estimation of phyto constituents from Terminalia chebula, (King of Medicine) by High Performance Thin Layer Chromatography (HPTLC) method. Methods: An in vitro study on the efficacy of methanol extract of T.chebula was carried out. ...

In the present report, generation of Tantalum oxyfluoride and oxynitride upon ammonolysis gel obtained from modified tantalum-alkoxo complexes is reported. To best our knowledge, this first report formation tantalum thin films via β-diketone complex [Ta(OEt)4(CF3COCH2COCH3)]m. The integration nitrogen fluorine in lattice sites metal oxides leads to significant reduction bandgap, resulting their...

In the present work electrochemical deposition of hydroxyapatite using simulated body fluid (SBF) as an electrolytic medium was carried out on Ta and Ta/TaN coatings BIOLINE stainless steel SS316LVM (SS). The performed each substrate for 3000 6000 s, at different potentials were determined from cyclic voltammetry. best conditions found −1.4 V bare SS −1.7 coating. structural characterization by...

Thermophilic and alkaliphilic lipases are meeting a growing global attention as their increased importance in several industrial fields. Over 23 bacterial strains, novel strain with high lipolytic activity was isolated from Southern Sinai, Egypt, and it was identified as Geobacillus thermoleovorans DA2 using 16S rRNA as well as morphological and biochemical features. The lipase was produced in ...

The reactions of Te, TeCl4 and MC15 (M = Nb, Ta) in a sealed evacuated ampoule at 170 °C yield Te4(NbCl6)2 and Te4(TaCl6j2 as black, moisture sensitive crystals. Te4(TaBr6)2 is obtained from Te2Br and TaBr3 at 175 °C, and Te4(Ta2OBr1()) is obtained in small yields as byproduct. The crystal structure determinations (all triclinic, PI, lattice constants for Te4(NbCl6)2: a = 654,2 pm, b = 673,9 pm...

The effective interatomic pair potentials for Ti, Zr, Hf, V, Nb, Ta and their hydrides are obtained by inverting the ab initio cohesive energy curves based on the lattice inversion method, and then the inverted pair potentials are used to calculate the mechanical and thermal properties of these hydrides.  2002 Published by Elsevier Science B.V.

BACKGROUND AND AIM Metabolic acidosis is common in patients with chronic kidney disease and is associated with increased mortality in hemodialysis patients. However, this relationship has not yet been determined in peritoneal dialysis (PD) patients. METHODS This prospective observational study included a total of 441 incident patients who started PD between January 2000 and December 2005. Usi...

Data dealing with the assessment of heavy metal pollution in road dusts in Jeddah, Saudi Arabia and its implication to human health risk of human exposure to heavy metals, are scarce. Road dusts were collected from five different functional areas (traffic areas (TA), parking areas (PA), residential areas (RA), mixed residential commercial areas (MCRA) and suburban areas (SA)) in Jeddah and one ...

BACKGROUND Carbon tetrachloride (CCl4) is a well-known hepatotoxin and exposure to this chemical is known to induce oxidative stress and causes liver injury by the formation of free radicals. Acute and chronic renal damage are also very common pathophysiologic disturbances caused by CCl4. The present study has been conducted to evaluate the protective role of the aqueous extract of the bark of ...
