Sr(NO3)2, Al(NO3)3, NH2CONH2, Eu2O3 and Dy2O3 are used as the raw materials for the preparation of SrAl2O4 (RE: Eu, Dy) precursor by the combustion synthesis technique (CST), which is widely known to prepare nano sized phosphors. The influence of varied concentration of Dy on crystal structure and optical properties is analyzed by means of Xray diffraction (XRD), scanning electron microscopy (S...

7-Hydroxystaurosporine (UCN-01) infused for 72 hours by continuous i.v. infusion induced insulin resistance during phase I clinical trials. To understand the mechanism for this observation, we examined the effect of UCN-01 on insulinstimulated glucose transport activity with 3-O-methylglucose in isolated rat adipose cells. UCN-01 inhibits glucose transport activity in a dose-dependent manner at...

OBJECTIVES The aim of this study was to compare the effects of four different mouthrinse containing propolis solutions and mouthrinse containing 0.2% chlorhexidine (CHX) on oral microorganisms and human gingival fibroblasts. METHODS Four different solutions of propolis were prepared and propylene glycol and alcohol were used as solvents for each propolis sample. Mouthrinse containing propolis...

Six nitrogen-, sulfurand cyclopropane-containing derivatives of cholestanol were examined as inhibitors of growth and sterol biosynthesis in the trypanosomatid protozoan Crithidia fasciculata. The concentrations of inhibitors in the culture medium required for 50% inhibition of growth were 0.32 pM for 24-thia-5a,20tcholestan-38-01 (2), 0.009 FM for 24-methyl-24-azaSa,2O.+holestan-38-01 (3), 0.9...

We investigated the effects of fish meal (FM) in beef cattle diets on growth performance, carcass characteristics, and fatty acid (FA) composition of longissimus muscle in 63 yearling steers (335 +/- 23 kg). High-moisture corn and alfalfa silage diets were supplemented with either a corn gluten/blood meal mixture or FM at 10% of the diet. Fish meal contained (as-is basis) 5.87 g/kg eicosapentae...

Background: The direct effect of some opioids on immune cells has been demonstrated. The aim of this study was to assess the apoptotic effect of opium on Jurkat T lymphocyte cells. Methods: Different concentrations of opium (2.86 × 10-3 to 2.86 × 10-11 g/ml) were added to 24-well plates containing 5 × 105 Jurkat cells. Apoptotic events were assessed after 6, 24, and 72 hours by flow-cytometric...

Cell damage induced by free radicals has been implicated as causal factor in a wide variety of human diseases such as cancer, neurodegenerative disorders. Scientific recognition of natural antioxidants may be helpful in preventing many diseases. Aqueous Date fruit extract (ADFE)- PC12 cell line. ADFE at concentrations of 0.1-10% containing 0.005% H2O2 and H2O2 at concentrations of 0.01-1% conta...
