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...

The alkaline phosphatase activities of 6-thiopurine-sensitive and -resistant sublines of Sarcoma 180 were exam ined in a further study of these enzymes, which have a role in the resistance of Sarcoma 180/TG to 6-thioguanine and 6-mercaptopurine. Both neoplasms possessed particulate-bound alkaline phosphatase enzymes labeled A and B on the basis of their ease of solubilization from the particula...

Bone resorption, characterized by the solubilization of both the mineral and the organic components of the osseous matrix, was obtained in tissue culture under the action of parathyroid hormone (PTH). It was accompanied by the excretion of six lysosomal acid hydrolases, which was in good correlation with the progress of the resorption evaluated by the release of phosphate, calcium 45 or hydroxy...

Canine microsomal signal peptidase activity was previously isolated as a complex of five subunits (25, 22/23, 21, 18, and 12 kDa). Two of the signal peptidase complex (SPC) subunits (23/23 and 21 kDa) have been cloned and sequenced. One of these, the 21-kDa subunit, was observed to be a mammalian homolog of SEC11 protein (Sec11p) (Greenburg, G., Shelness, G. S., and Blobel, G. (1989) J. Biol. C...

Aims: This study aimed to isolate and characterize thermotolerant phosphate solubilizing bacteria (PSB) for potential agricultural applications. We identify promising PSB isolates evaluate their traits.
 Study Design: Conducted a comprehensive screening of selected three top candidates based on phosphate-solubilizing index. These underwent various tests, including thermotolerance assessmen...

background and objectives: azotobacter is a diazotroph bacterium reported to possess various plant growth-promoting characteristics.the aim of this study was to isolate azotobacter strains capable of fixing nitrogen and effectively hydrolyzing both organic and inorganic pi compounds. materials and methods: in this study, soil samples collected from a diverse range of slightly alkaline soil type...

introduction: the aim of this study was to evaluate the correlation between serum levels of ovarian and gonadotropin hormones, age and number of follicles with follicular alkaline and acid phosphatase activity in infertile women under controlled ovarian hyperstimulation. methods: after collection of follicular fluid and calculation of the number of follicles, the specific activity of alkaline (...

enzymes is due to a more specific process than generalizedcell damage or loss (Holdsworth & Coleman, 1975). We have now attempted to make an initial separation of these enzymes from other biliary proteins, before investigating their relationship with the bile-canaliculus region of the hepatocyte plasma membrane. Fresh sheep bile was treated with solid protamine sulphate and centrifuged to remov...
