A mechanism of the transport of nanocrystalline doped calcium carbonatephosphates through the membrane on the model of interaction with phospholipids is considered. Nanocrystalline doped calcium carbonate – phosphates are perspective to transport of the cations in a living cell. Kinetics of the synthesis of nanocrystalline doped calcium carbonatephosphates are non-linear kinetics. Biomaterial b...

The separation of myo-inositol phosphates by ion pair, reverse-phase high performance liquid chromatography has been investigated. The retention of the inositol phosphates is dependent on both the polarity of the hetaeron utilized and on the pH of the solvent. A method is presented which permits the isocratic separation of multiple forms of inositol phosphates including isomers of myo-inositol ...

thimerosal, which is approximately 50% mercury by weight is a preservative widely used in vaccines since the 1930’s. it meets the requirements for a preservative as set forth by pharmacopeia challenge test and has been shown to be effective against a broad spectrum of pathogens. in july 1999, the public health service agencies and vaccine manufacturers agreed that thimerosal should be reduced o...

protein aggregation and precipitation is associated with many debilitating diseases including alzheimer's, parkinson's, and light-chain amyloidosis. β-casein, a member of the casein family, has been demonstrated to exhibit chaperone-like activity to protect protein form aggregation. hofmeister salts (lyotropice series) are a class of ions which have an effect on the solubility and also the stab...

Heats of immersion of alkali and alkaline earth metaphosphates in some aromatic hydrocarbons were measured with a twin microcalorimeter to investigate the interaction of the interfaces between the phosphates and the hydrocarbons. The heats of immersion in benzene for the phosphates with long chains were lower than those for the phosphates with short chains. The dependence of heat of immersion o...

The accessibility of phosphates towards ethylnitrosourea was studied in tRNA/aminoacyl-.tRNA synthetase complexes and in the ternary aminoacyltRNA/EF-Tu/GTP complex. When the tRNA is complexed to aminoacyl-tRNA synthetases, several phosphates are protected against the alkylation agent, the protection patterns varying according to the tRNA/aminoacyl-tRNA synthetase system. However in all cases p...
