in the current investigation a novel nano hybrid adsorbent mcm-41/n-(3-trimethoxysilyl)-propyl)diethylenetriamine (mcm-41/tmspdeta) was prepared and was characterized using dls (dynamic light scattering), fourier transform infrared (ftir), x-ray diffraction (xrd), brunauer–emmett–teller (bet) analytical techniques and transmission electron microscopy (tem). the synthesized mcm-41/tmspdeta adsor...

Fe(II) was added to U(VI)-spiked suspensions of hydrous ferric oxide (HFO) or hematite to compare the redox behaviors of uranium in the presence of two different Fe(III) (oxyhydr)oxides. Experiments were conducted with low or high initial sorption density of U(VI) and in the presence or absence of humic acid (HA). About 80% of U(VI) was reduced within 3 days for low sorbed U(VI) conditions, wit...

Solid-phase immunosorbent hemadsorption (SPIHAtl) for specific IgM detennination has been introduced for rubella serodiagnosis in combination with hemagglutination inhibition test (HAl) during the outbreak prevaDed from September 1983 to August 1984 with its peak in March. By HAl test, 92.7% of patients with apparent rubella infection whose first blood was obtained within 3 days after rash show...

We construct Tchebyshev-II (second kind) weighted orthogonal polynomials U (γ) n,r (u, v, w), γ > −1, on the triangular domain T. We show that U (γ) n,r (u, v, w), n = 0, 1, 2, . . . , r = 0, 1, . . . , n, form an orthogonal system over T with respect to the Tchebyshev-II weight function. AMS Subject Classification: 42C05, 33C45, 33C70

Human U-II (urotensin-II), the most potent vasoconstrictor peptide identified to date, is associated with cardiovascular disease. A single nucleotide polymorphism (S89N) in the gene encoding U-II (UTS2) is associated with the onset of Type 2 diabetes and insulin resistance in the Japanese population. In the present study, we have demonstrated a relationship between plasma U-II levels and the pr...

Human urotensin II (U-II), the most potent vasoconstrictor peptide identified to date, and its receptor (UT) are involved in hypertension and atherosclerosis. Acyl-coenzyme A:cholesterol acyltransferase-1 (ACAT-1) converts intracellular free cholesterol into cholesterol ester (CE) for storage in lipid droplets and plays an important role in the formation of macrophage-derived foam cells in athe...

Endogenous regulators, such as angiotensin-II (AngII), endothelin-1 (ET-1) and urotensin-II (U-II) are released from various cell types and their plasma levels are elevated in several cardiovascular diseases. The present study evaluated a potential crosstalk between these systems by investigating if the myocardial effects of U-II are modulated by AngII or ET-1. Effects of U-II (10(-8), 10(-7), ...

Urotensin II (U-II), a vasoactive cyclic neuropeptide which activates the G protein-coupled receptor UT receptor, exerts various cardiovascular effects and may play a role in the pathophysiology of atherosclerosis. In this study, we report that the UT receptor is expressed and functional on human PBMC and rat splenocytes. PBMC surface expression of the UT receptor was mainly found in monocytes ...
