Thermostable composite materials based on solid magnesium phosphate and calcium phosphate, as well hybrid binders have been developed investigated. Thermal phase transformations of the composites studied. Strength characteristics determined in temperature range 20–1000 °C. It is shown that obtained high strength properties (compressive reaches 120–130 MPa) are characterised by thermal stability...

a field trial was canied outon60 volunteers selected in yazd province, central iran, with a vaccine containing killed promastigotes of l. major prepared by the razi institute, hessarak. during these phase i studies which lasted for more than two years, we examined acceptable doses of the vaccine alone or mixed with bcg. the results so far indicate that 50 to 1000 µg of the vaccine alone can be ...

Abstract The 4,6-α-glucanotransferases of the glycoside hydrolase family 70 can convert starch into isomaltooligosaccharides (IMOs). However, no thermostable have been reported to date, limiting their applicability in conversion industry. Here we report identification and characterization a 4,6-α-glucanotransferase from Bacillus coagulans DSM 1. gene was cloned recombinant protein, called BcGtf...

To understand the roles of metal ions on the catalytic properties and thermostability of the thermostable beta-galactosidase of Saccharopolyspora rectivirgula, a thermophilic actinomycete, we have investigated the binding kinetics and requirements of divalent metal ions by equilibrium dialysis, titration, and metal ion buffer techniques. We found that the monomeric multimetal enzyme (M(r) 136,9...

Nucleoplasmin, an acidic thermostable protein abundant in the nucleus of Xenopus laevis oocytes, has been found to dissociate complexes of pUC19 DNA and protein phi 1, an intermediate protamine present in ripe sperm from the mollusc Mytilus edulis. Cruder preparations of nucleoplasmin, such as the amphibian oocyte S150 extract and its thermostable fraction, also dissociate the heterologous DNA-...

hepatitis c virus (hcv) infection is highly prevalent in thalassemic patients, and this may decrease the serum antibody response to hepatitis b virus (hbv) vaccine. there is also some alteration of the immune system in multi-transfused thalassemic patients, as a consequence of iron overload. we investigated whether hcy infection may reduce the effectiveness of hby vaccine in multi - transfused ...
