Hydroxyapatite (HA) or calcium carbonate (CaCO3) formed on an organic polymer of agarose gel is a biomaterial that can be used for bone tissue regeneration. However, in critical bone defects, the regeneration capability of these materials is limited. Mesenchymal stem cells (MSCs) are multipotent cells that can differentiate into bone forming osteoblasts. In this study, we loaded MSCs on HA- or ...

The aims of this study were: (1) to correlate surface (SH) and cross-sectional hardness (CSH) with microradiographic parameters of artificial enamel lesions; (2) to compare lesions prepared by different protocols. Fifty bovine enamel specimens were allocated by stratified randomisation according to their initial SH values to five groups and lesions produced by different methods: MC gel (methylc...

The purified factor VIII has been found to be a macromolecular glycoprotein with a major subunit of 240,000, as shown by sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis. Carbohydrate analysis of factor VIII gave values of 1% sialic acid, 2.8% hexosamine, and 1-2% hexose (mannose, galactose, and fucose). The lipid content was found to be less than 5% of the protein content, and i...

169 Abstract Two proteinous compounds (A and B) were isolated by gel filtration chromatography of the acetone precipitate of the aqueous extract of Portulaca oleracea L. plant. Comparative apparent molecular weights determination by gel filtration using standard proteins gave a value of 28184 and 2291 dalton respectively.The effect of the isolated proteinous compounds A , B and the hormone of i...

The objects of this study were to develop the topical usage of ibuprofen gel and evaluate the permeability status of the prepared gel. Ibuprofen gel was prepared by incorporation of mustard oil and ethanol for improving the ibuprofen release in the topical preparation at different ratio low, medium and high concentration. In general marketed ibuprofen gel, ointment or creams contain ibuprofen a...

in order to investigation of nitrogen fertilizer split application effect on quantity yield and grain quality of rice varieties, an experiment was carried out based on rcbd design as split plot experiment in three replications in langroud in 2006. mainand sub factor were variety (hashemi and bahar 1) and five nitrogen fertilizer split application (split of 150 kg.ha-1 n at transplanting, stemmi...

Formation and structure of whey protein heat-induced gels (100 mg mL-1) through heat treatment at 80 °C and pH modifications at three pH values of acidic (2), isoelectric (5.6) and neutral (7) were studied. The obtained results indicated that the nature of the primary gel networks was different at each pH value. The heat-induced gels produced at pH of 2 and 7, had acceptab...

BACKGROUND Ga-labeled radiotracers are increasingly used for PET imaging. During the labeling procedure, formation of (68)Ga-colloid may occur. Upon i.v. injection, (68)Ga-colloid will accumulate rapidly in the liver, spleen, and bone marrow, resulting in reduced target-to-background ratios. In this study, we applied a thin layer chromatography (TLC) method to measure colloid content and we stu...

Flour is the main energy source for human and an important ingredient in food processing, example to be used as fillers, thickeners, gel, film forming adhesive. This research aims analyze characteristics of physicochemical properties assess potential utilization palado flour (Aglaia sp) based on its characteristics. The method employed two steps, namely introduction research, which included pro...

The aim of this study was to investigate the effects of polyacrylic acid polymers (Ultrez 10, Ultrez 20, Carbopol 980, and Carbopol 940) on the viscosity and the in vitro permeation of phenolic compounds from the gel prepared from natural horse chestnut seed extract. Experiments were performed in the presence and in the absence of peppermint oil (Mentha piperita). Our results showed that pepper...
