Effect of hydrogen sulfide in comparison to atorvastatin on endothelial damage in cholesterol-fed rabbits

Hydrogen sulfide (H₂S) is an endogenous gaseous molecule, functioning as a physiological regulator. This study aimed to investigate the role of H₂S in atherosclerosis. Rabbits receiving high cholesterol were given atorvastatin (10 mg/kg/day, orally) or sodium sulfide (1.1 mg/kg/day, intramuscular) 2 weeks after commencement of high-cholesterol diet and continued for 4 weeks. Serum lipid profiles, lipid peroxidation indexed as malondialdehyde, glutathione, superoxide dismutase, the vascular adhesion molecule-1, and aortic vascular endothelial growth factor were determined. Rabbits receiving a high-cholesterol diet showed elevated levels of total serum cholesterol, triglycerides, low-density lipoprotein cholesterol, malondialdehyde and vascular adhesion molecule-1, and aortic vascular endothelial growth factor expression and lower levels of high-density lipoprotein cholesterol, glutathione, and superoxide dismutase. Treatment with atorvastatin and sodium sulfide has beneficial effects on serum lipid profile, oxidative damage, vascular adhesion molecule-1, and aortic expression of vascular endothelial growth factor.     

Adsorption models of Cs radionuclide and Sr (II) on some Egyptian soils

Distribution of cesium (¹³⁴Cs and ¹³⁷Cs) and strontium (Sr-II) between soil/water phases depends on many factors such as concentration of these ions between phases, the cation exchange capacity (CEC) of the soil as well as its clay content, chemical composition (especially Na, K, Ca, and Mg ions), grain size distribution, calcite, iron oxide content, and organic coatings. Distribution coefficients (Kd) of cesium (labeled with ¹³⁷Cs) and strontium were measured on the grain size distributions ≥32 μm of four soil samples. These soils were obtained from four different locations within Inshas site in Egypt and three groundwater samples were obtained from the same site locations. X-ray diffraction showed that the soil samples consisted mainly of quartz mixed with the minor amounts of kaolonite and clay minerals. Sorption experiments were carried out at strontium aqueous concentrations range 10⁻⁷ to 10⁻⁴ mol l⁻¹. The CEC and Kds for cesium and strontium were measured at the same metal concentrations range. Distribution coefficients of cesium were found to be influenced by the composition of the soil, while the distribution coefficients of strontium were found to depend on calcium concentrations in the soil/groundwater system. The aim of this study was to determine the safety assessment of disposal ¹³⁷Cs radionuclide and Sr(II) in the aquifer regions inside the Inshas site. Sequential extraction tests showed that, strontium was associated with the carbonate fractions and majority of cesium was sorbed on the iron oxides and the residue.
