Improved insulin sensitivity associated with reduced mitochondrial complex IV assembly and activity
No full textMice lacking Surf1, a complex IV assembly protein, have 50-70% reduction in cytochrome c oxidase activity in all tissues yet a paradoxical increase in lifespan. Here we report that Surf1-/- mice have lower body (15%) and fat (20%) mass, in association with reduced lipid storage, smaller adipocytes, and elevated indicators of fatty acid oxidation in white adipose tissue (WAT) compared with control mice. The respiratory quotient in the Surf1-/- mice was significantly lower than in the control animals (0.83- 0.93 vs. 0.90-0.98), consistent with enhanced fat utilization in Surf1-/- mice. Elevated fat utilization was associated with increased insulin sensitivity measured as insulinstimulated glucose uptake, as well as an increase in insulin receptor levels (2-fold) and glucose transporter type 4 (GLUT4; 1.3-fold) levels in WAT in the Surf1-/- mice. The expression of peroxisome proliferator- activated receptor β-coactivator 1 (PGC-1α) mRNA and protein was up-regulated by 2.5- and 1.9- fold, respectively, in WAT from Surf1-/- mice, and the expression of PGC-1α target genes and markers of mitochondrial biogenesis was elevated. Together, these findings point to a novel and unexpected link between reduced mitochondrial complex IV activity, enhanced insulin sensitivity, and increased mitochondrial biogenesis that may contribute to the increased longevity in the Surf1-/- mice.-Deepa, S.

Discussion: Remoulded shear strength at plastic and semi-solid states
No full textThe undrained shear strength of remoulded soils is of great concern in geotechnical engineering applications. This study aims to develop a reliable approach for determining the undrained shear strength of remoulded fine-grained soils, through the use of index test results, at both the plastic and semi-solid states of consistency. Experimental investigation and subsequent analysis involving a number of fine-grained soils of widely varying plasticity and geological origin have led to a two-parameter linear model of the relationship between logarithm of remoulded undrained shear strength and liquidity index. The numerical values of the parameters are found to be dependent to a lesser extent on the soil group and to a greater extent on the soil state. Based on the values of regression coefficient, ranking index and ranking distance, it seems that the relationship represents the experimental results well. It may be pointed out that the possibility of such a relationship in the semi-solid state of a soil has not been explored in the past. It is also shown that the shear strength at the plastic limit is about 32–34 times that at the liquid limit

Electrochemical behaviour of Solanum trilobatum plant extract on stainless steel in natural sea water environment
No full textAbstract In the present work, inhibition efficacy of Solanum trilobatum leaves (STL) extract on the corrosion of stainless steel in natural sea water environment is studied by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) measurements. Results from the study indicate that the inhibition efficiency increased with increase of inhibitor concentration and achieved maximum of more than 80% for polarization as well as impedance measurements. Electrochemical measurements show that both polarization and charge transfer resistances increases with increase of inhibitor concentration. The adsorption of STL inhibitor on the stainless steel surface obeys Frumkin adsorption isotherm and the calculated values of ∆G ads indicate that the adsorbed layer is spontaneous and stable one. Key words: Electrochemical, inhibition, stainless steel and Frumkin Cite this article as: Deepa Rani P,Selvaraj S.

Ensuring The Homogeneity OF Spray Pyrolised SnS Thin Films Employing XPS Depth Profiling
No full textSnS thin films were prepared using chemical spray pyrolysis (CSP) technique. p-type SnS films with direct band gap of 1.33 eV and having very high absorption coefficient were obtained with the optimized deposition conditions. In this paper we focus on investigating the uniformity and phase purity of the hence deposited SnS films employing Raman and X-ray Photoelectron Spectroscopy (XPS) analysis. Raman Spectra of the films had only single peak corresponding to the Raman active Ag mode at 224 cm(-1) which is characteristic for phase-pure SnS thin films. Detailed XPS analysis on these samples were performed by scanning the peaks for Sn, S, and O with high resolution to estimate the chemical states and composition. Employing Ar-ion sputtering, the depth profiles showing variation in concentration and binding energies of S, Sn, O over the sample thickness were obtained and the uniformity in composition along the thickness has been discussed in detail
