The complement anaphylatoxin C5a and its seven-transmembrane segment (7TMS) receptor play an important role in host defense and in a number of inflammation-associated pathologies. The NH(2)-terminal domain of the C5a receptor (C5aR/CD88) contributes substantially to its ability to bind C5a. Here we show that the tyrosines at positions 11 and 14 of the C5aR are posttranslationally modified by th...

Abstract Background Health problem that affects hard tissues of the teeth is dental caries, which experienced by around 2.3 billion people in world, with prevalence Indonesia reaching 88.8. Direct pulp capping (DPC) a vital therapy used to maintain vitality. Calcium hydroxide (Ca(OH)2) gold standard material, but has poor adhesion dentin and mechanical properties, bacterial infiltration, format...

Abstract The (early) hydration mechanisms of two different binder systems used for shotcrete were investigated: the so far almost unexplored low sulfate (spray binder), in field dry-mix shotcrete; and ordinary Portland cement, accelerated by aluminum sulfate, widely wet-mix shotcrete. basis fast setting spray is rapid dissolution C 3 A subsequent formation flaky CO -AFm phases. Thereby induced ...

The very early hydration behavior of a hydraulic binder phase, ye’elimite, Ca4Al6O12SO4, in the absence and presence calcium sulfate, has been investigated. A time-resolved situ multinuclear magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopic suite involving 1H 27Al MAS as well two-dimensional multiple quantum (MQMAS) experiments employed to detect transient species govern...

A unique process for regenerating calcium-based sorbents which are in the form of calcium sulfide was demonstrated by employing thermogravimetric analysis (TGA). The process converts calcium sulfide to calcium oxide by subjecting particles of the material to repeated cycles of oxidation and reduction at temperatures between 950 and 1100 °C. During each cycle a small portion of material is first...

The effect of coexisting metals in a sample on the determination of lead and cadmium in plastics used for food contact materials was investigated. In the official method specified in the Japanese Food Sanitation Law, contents of lead and cadmium are determined by a dry incineration method using sulfuric acid. It was assumed that sometimes, coexisting metals in a sample may form insoluble sulfat...

Calcium sulfate (CS) has been used clinically as a bone- or void-filling biomaterial, and its resorptive properties have provided the prospect for use release mechanism local antibiotics to control biofilms. Here, we aimed test CS beads loaded with three antifungal drugs against planktonic sessile fungal species assess whether these could be harnessed provide consistent of antifungals at biofil...

ABSTRACT The objective of this study was to develop a novel subgingival sustained-release system for local delivery bioactive minocycline hydrochloride periodontal disease treatment in dogs. incorporated the Minocycline hydrochloride-Calcium-Dextran sulfate sodium into thermoresponsive Pluronic F127 hydrogel. sustained release from up 10 days and kinetics fit power law model. medium had signifi...

o bjectives: the aim of this study was to assess the cytotoxic effects and osteogenic activity of recombinant human bone morphogenetic protein (rhbmp2) and nano-hydroxyapatite (n- ha) adjacent to mg-63 cell line. mat erials and methods: to assess cytotoxicity, the 4,5-dimethyl thiazolyl-2,5-diphenyl tetrazolium bromide (mtt) assay was used. alkaline phosphatase (alp) activity and oste- ogenic a...
