objectives: osteoblasts are the most important cells in the osseointegration process. despite years of study on dental implants, limited studies have discussed the effect of saliva on the adhesion process of osteoblasts to implant surfaces. the aim of this in vitro study was to evaluate the effect of saliva on morphology and differentiation of osteoblasts attached to implant surfaces. materials...

ingested corrosive substances produce different injuries, ranging from minor gastro esophageal burns to death, depending on the agent type, amount, concentration, and duration of substance exposure. the purpose of this study was to investigate the outcomes and different causes of mortality in patients ingesting caustic substances. in a prospective study, between april 1999 and january 2006, a t...

in this research, graphene was synthesized by chemical vapor deposition (cvd) method in atmosphere pressure (14.7 psi). different functionalization method was used for oxidizing of graphene such as acid and alkaline treatments. the functionalized graphene (fg) was characterized by ftir and raman spectroscopy. nanofluid with water and different concentration (0.05, 0.15 and 0.25 wt %) of fg were...

biosolids must be stabilized in order to reduce odors, which have been noted as a major concernwith respect to alkaline stabilization. stabilization is designed to address potential putrefaction processes,odiferous releases and vector attraction concerns. also, most alkaline processes are open systems in whichtemperature and mixing are more difficult to control, and factors such as increased pr...

the lalezar granitoids crop out within volcanic successions of the urumieh-dokhtar magmatic assemblage (udma). these granitoids have a range from gabbro-diorites to granites in composition. the mineral compositions of the most felsic rocks are characterized by the abundances of na-plagioclase, quartz, alkali feldspar, biotite and hornblende. in the gabbro-diorite rocks, plagioclase (ca-rich), h...

INTRODUCTION Laboratory and clinical data have implicated endotoxin as an important factor in the inflammatory response to cardiopulmonary bypass. We assessed the effects of the administration of bovine intestinal alkaline phosphatase (bIAP), an endotoxin detoxifier, on alkaline phosphatase levels in patients undergoing coronary artery bypass grafting. METHODS A total of 63 patients undergoin...

The gene encoding Thermus caldophilus GK24 (Tca) alkaline phosphatase was cloned into Escherichia coli. The primary structure of Tca alkaline phosphatase was deduced from its nucleotide sequence. The Tca alkaline phosphatase precursor, including the signal peptide sequence, was comprised of 501 amino acid residues. Its molecular mass was determined to be 54¿ omitted¿760 Da. On the alignment of ...

Alkaline phosphatase prepared from mammalian cell cultures was found to have alkaline inorganic pyrophosphatase activity. Both of these activities appear to be associated with a single protein, as demonstrated by: (1) concomitant purification of alkaline phosphatase and alkaline inorganic pyrophosphatase; (2) proportional precipitation of alkaline phosphatase and inorganic pyrophosphatase activ...

The aim of this study was to Investigate the toxic effects of chromium and cadmium on the activity of two isoenzymes of alkaline phosphatase in vitro and in vivo experiments. Oral administration and peritoneal injection of  CdCl2 or CrCl3 in rats reduced serum alkaline phosphatase by 21.5℅ and 25.5℅ respectively. At the same time high molecular weight alkaline phosphatase was elevated by 138℅ a...

BACKGROUND Alkaline α-amylases have potential applications for hydrolyzing starch under high pH conditions in the starch and textile industries and as ingredients in detergents for automatic dishwashers and laundries. While the alkaline α-amylase gains increased industrial interest, the yield of alkaline α-amylases from wild-type microbes is low, and the combination of genetic engineering and p...
