BACKGROUND Similar to inflammatory cells, peripheral blood mononuclear cells (PBMCs) can also infiltrate in to kidney and urinary tracts and subsequently excreted by urine. In this study we determined the viability rate and response to phytohemagglutinin-A (PHA) of human PBMCs in normal urine. METHODS A number of 1×10(6) ficoll-hypaque isolated PBMCs were dispensed in 1 ml normal urine and 6 ...

Semiconductor photocatalysis technology is an environmentally friendly and efficient emerging technology. This method can use sunlight as a driving force to quickly decompose organic pollutants in water bodies. Zinc oxide (ZnO) tungsten (WO3) photocatalysts absorb participate photocatalytic degradation reactions due their relatively narrow band gap. Highly photosensitive WO3 nanofibers ZnO/WO3 ...

Several studies have demonstrated beneficial effects of supplemental trivalent Cr in subjects with reduced insulin sensitivity with no documented signs of toxicity. However, recent studies have questioned the safety of supplemental trivalent Cr complexes. The objective of this study was to evaluate the cytotoxic and genotoxic potential of the Cr(III) complexes (histidinate, picolinate, and chlo...

Abstract Large band gap and high electron–hole pair recombination rate limits practical application of TiO 2 as a photocatalyst. Different methods are developed to remove or minimize the aforementioned limitations . In this study, nanoparticles were coupled with ZnO CdO address above-mentioned hence enhance photocatalytic activity , ZnTiO CdZnTiO nanocomposites synthesized by simple co-precipit...

introduction: basal cell carcinoma (bcc) is the most common cutaneous malignancy. proffered treatment for these lesions is surgery. based on patient’s age, drug allergies, and place of lesions, surgery may not be the best option, and alternative treatments should be considered. pulsed dye laser (pdl) may be a good alternative therapy. the aim of the present study was to determine the effectiven...

In 1967 the first work in solid state dye laser was performed by doping rhodamine dyes Polymethylmethacrylate (PMMA) materials. Since then some materials like various types of polymers, co-polymers, poly composite glasses have been used as host matrices for different dyes. Polymers suffer from limited mechanical and thermal stability. Hence can be alternative hosts. However, because high proces...

up to now, lots of materials such as active carbon, iron, manganese, zirconium, and metal oxides have been widely used for removal of dyes from contaminated water. among these, ferrite nanoparticle is an interesting magnetic material due to its moderate saturation magnetization, excellent chemical stability and mechanical hardness. graphene, a new class of 2d carbonaceous material with atom thi...

INTRODUCTION Success of non-surgical root canal treatment is predicted by meticulous cleaning and shaping of the root canal system, three-dimensional obturation and a well-fitting "leakage-free" coronal restoration. The techniques of obturation that are available have their own relative position in the historical development of filling techniques. Over the years, pitfalls with one technique hav...
