In recent years, zinc oxid nanotubes have attracted much attention. The direct use of , zinc oxidnanotubes modified by SiO2 as recoverable catalysts for organic reactions is very rare. The catalystswere characterized by XRD. The average particle size of ZnO catalysts is 57 nm and there are highdensitydefects on nanotubes surfaces . A simple and efficient method for the imidazol derivativessynth...

Research on antioxidants proceeds at full speed after a partial decline of public interest, when claims on effectiveness of mega doses of vitamin C proved unfounded. The main role of antioxidants is to liquidate the uncontrolled production of reactive oxygen species (ROS) that is being linked to pathogenesis of cardiovascular disease (CVD), malignancy, diabetes type 2, mechanism of infection, f...

INVESTIGATION OF THE INFLUENCE ZINC OXID CONTENT AND SCAFFOLD MORPHOLOGY ON MECHANICAL PROPERTIES POLY(ε-CAPROLACTONE) / OXIDE NANOCAMPOSITE SCAFFOLDS

Introduction: Mutations in the delta sarcoglycan gene (d-SG) cause limb-girdle muscular dystrophy type 2F with structural and functional alterations in cardiac, smooth and skeletal muscle. The objective of the present study was to improve information about changes in vascular reactivity of the thoracic aorta and the coronary artery in the perfused heart of the d-SG-null mutant mouse model. ...

The phage-shock protein PspE and GlpE of the glycerol 3-phosphate regulon of Salmonella enterica serovar Typhimurium are predicted to belong to the class of thiosulfate sulfurtransferases, enzymes that traffic sulfur between molecules. In the present study we demonstrated that the two genes contribute to S. Typhimurium virulence, as a glpE and pspE double deletion strain showed significantly de...

Vascular endothelium plays an essential role in the regulation of the vascular tone, contributing to maintaining the balance between vasodilatation – vasoconstriction, owing to the production of endogenous nitric oxide (NO) under the action of different endogenous and exogenous factors. The loss of the functional integrity of the vascular endothelium, called endothelial dysfunction, in differen...
