This enhanced stability of sp(3) hybridized atoms within the bulk region with respect to graphitization is discussed in terms of carbon bond rearrangement due to the thermal decomposition of t-PA-like fragments. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3359714]“
“Corrosion protection performance of epoxy polyamide coatings containing polypyrrole (PPy) composites for steel has been studied. PPy and its composites LEE011 price have been synthesized chemically using potassium permanganate and potassium per sulfate as oxidants. The PPy has been characterized by four

probe method for conductivity, atomic absorption spectroscopy for elemental analysis, and Fourier transform infrared spectra for proving selleck inhibitor the incorporation of dopant in this polymers. The X-ray diffraction (XRD) study has revealed the presence of manganese dioxide in the polymer. The elemental analysis and the thermo gravimetric analysis measurements showed that the presence of manganese dioxide in the polymer is about 75%. The thermal stability of deprotonated polymer has improved. Electrochemical impedance spectroscopic analysis indicated that the epoxy polyamide/PPy-MnO(2) coating showed the maximum resistance value of 2.196 x 10(7)

“Evidence linking vitamin D to cardiovascular (CV) health has accumulated in recent years: numerous epidemiologic studies report deficiency as a significant CV risk factor, SC79 and rodent models suggest that active vitamin D can modulate critical remodeling processes, including cardiac hypertrophy and extracellular matrix remodeling. The presence of vitamin D signaling machinery within the human heart implies a direct role for this hormone in cardiac physiology and may explain

associations between vitamin D status and CV outcomes. Heart failure (HF) represents a growing social and economic burden worldwide. Myocardial remodeling is central to HF development, and in the context of emerging evidence supporting mechanistic involvement of vitamin D, this review provides critical appraisal of scientific literature related to the role of vitamin D in CV disease, including data from epidemiologic and supplementation studies, as well as novel findings from animal models and in vitro work. Although associative data linking vitamin D and CV outcomes and evidence supporting a role for vitamin D in relevant pathogenic processes are both substantial, there are limited mechanistic data to indicate vitamin D supplementation as a viable therapeutic adjunct for the prevention of HF development following myocardial injury.”
“Xanthogranulomatous inflammation is rare, mainly involving the kidneys, histologically characterized by partial or complete replacement of the mucosa by granulation tissue with an abundance of foamy histiocytes, siderophages and multinucleated giant cells.
