The impact of coronary artery stenosis (CAS) on renal injury is unknown. Here we tested whether the existence of CAS, regardless of concurrent atherosclerosis, would induce kidney injury and magnify its susceptibility to damage from coexisting hypertension (HT). Pigs (seven each) were assigned to sham, left-circumflex CAS, renovascular HT, and CAS plus HT groups. Cardiac and nonstenotic kidney ...

This study is focused on synthesis of nano-colloidal silica via alkaline water glass solution. Sodium ions of water glass were removed by cation exchanging in a resin column to obtain the silicic acid which was titrated to the solution of sodium silicate. Concentration of the colloidal silica and pH value of the solutions were controlled using different concentrations of alkaline sodium silicat...

Crk-associated substrate (CAS) is a major tyrosine-phosphorylated protein in cells transformed by v-crk and v-src oncogenes and plays an important role in invasiveness of Src-transformed cells. A novel phosphorylation site on CAS, Tyr-12 (Y12) within the ligand-binding hydrophobic pocket of the CAS SH3 domain, was identified and found to be enriched in Src-transformed cells and invasive human c...

colloidal quantum dots offer broad tuning of semiconductor band structure via the quantum size effect. in this paper, we present a detailed investigation on the influence of the thickness of colloidal lead sulfide (pbs) nanocrystals (active layer) to the photovoltaic performance of colloidal quantum dot solar cells. the pbs nanocrystals (qds) were synthesized in a non-coordinating solvent, 1-oc...

the radiology diagnosis of primary hydatid disease of the kidney is possible when a renal mass is noted on the radiograph. part icula rly in the countries where this disease is prevalent. cha racteristic radiological signs, hydatiduria, eosinophili and specific examination such as casoni and weinberg tests are a ll helpful to assist the diagnosis. twelve cases of primary hydatid disease of the ...

central anticholinergic syndrome (cas) following general anesthesia (ga) is a well known syndrome in children and adults. many cases of cas have been previously reported in the literature. however, there are only two reports of post resuscitation cas after administration of small doses of atropine. hereby, we report a case of cas in a child undergoing complete dental restoration under ga after ...

Liquefaction is one of the most important and complex topics in geotechnical earthquake engineering. In recent years, passive site stabilization method has been proposed for non-disruptive mitigation of liquefaction risk at developed sites susceptible to liquefaction using colloidal nano-silica stabilizer. In this research, 4 box models were used to investigate the ability to uniformly deliver ...

Colloidal silica bonded refractory castables have been developed recently. It was found that colloidal silica is one of the best binders can substitute other binders such as cement in No Cement Castable (NCC) and Ultra Low Cement Castable (ULCC) refractories. Also composition of colloidal silica with appropriate additives resulted in a gel form which makes the initial strength. Moreover, the na...
