this study concerns about quantum chemical modeling behavior of 02 on cr (100)surface by using density functional theory (dft) by lanl2dz and 6 — 31g* basissets, we presented the results of our first principles electronic structure calculationson the 02 molecules and their interface with cr (100) surface. the chromium metalhas the body-centered cubic structure, and chromium cluster has five cr ...

subsequent to phytochemical investigation on scutellaria lateriflora (labiatae) from mazandaran provincein iran, the wax ester fraction of the leaves has been investigated. using tlc, cc glc and glc-ms, the alkyl esters of the epicuticular wax was analysed. total concentration of the esters was 35% and it was shown to be composed of a homologous series having various chain lengths in the range ...

In the dairy cow, late gestation and early lactation are characterized by a complexity of metabolic processes required for homeorhetic adaptation to needs fetal growth milk production. Skeletal muscle plays an important role in this adaptation. The objective study was characterize metabolome skeletal (semitendinosus muscle) serum cows context physiological changes occurring test effects dietary...

conclusions vancomycin nephrotoxicity is common but usually reversible and has readily manageable adverse effect. urine kim-1 was not more accurate than serum or urine creatinine in detecting vancomycin nephrotoxicity in our study population. results thirteen out of the 52 recruited patients (25%) developed nephrotoxicity, with a mean ± standard deviation onset of 11.46 ± 7.56 days. furosemide ...

Background: ABCD1 is a peroxisomal ABC transporter whose dysfunction causes X-linked adrenoleukodystrophy (X-ALD). Results: β-Oxidation of C26:0 as well as C22:0 acyl-CoA esters is impaired in X-ALD. ABCD3 accounts for residual β-oxidation activity in XALD fibroblasts. Conclusion: ABCD1 mediates very long-chain acyl-CoA ester β-oxidation without need for additional re-esterification by an acyl-...

In this research, the interaction of [CuL(DMF)], [NiL(DMF)] and [VOL(DMF)] (where L = ((E)-4-((2-amino-5-nitrophenylimino)methyl)benzene-1,3-diol)) complexes derived from tridentate Schiff base ligand with bovine serum albumin (BSA) and DNA was investigated via electronic absorption and fluorescence spectroscopy. The Ultraviolet-Visible (UV-Vis) spectra exhibited an isosbestic point for the com...

The unique fold of scorpion toxins is a natural scaffold for protein engineering, in which multiple disulfide bonds are crucial structural elements. To understand the respective roles of these disulfide bridges, a mutagenesis analysis for the four disulfide bonds, 12-63, 16-36, 22-46 and 26-48, of a representative toxin BmK M1 from the scorpion Buthus martensii Karsch was carried out. All cyste...

BACKGROUND Cachexia is among the most debilitating and life-threatening aspects of cancer. It represents a metabolic syndrome affecting essential functional circuits involved in the regulation of homeostasis, and includes anorexia, fat and muscle tissue wasting. The anorexigenic peptide alpha-MSH is believed to be crucially involved in the normal and pathologic regulation of food intake. It was...
