Abstract:

Local minimum appearing in the interionic pair potentials, when derived from local model pseudopotential, for Al (and some other polyvalent metals) remains as a long standing problem of clear understanding of its origin, although some attempts have been made by a few authors. The origin of this feature of local minimum is systematically investigated for the first time in this paper considering both the core size and the conduction electron density as variables. Interionic pair potential is derived from Ashcroft’s empty core model because it depends on these two variables only. Results of this

Phytate is a dominant form of organic phosphorus (P) in the environment. Complexation and precipitation with polyvalent metal ions can stabilize phytate, thereby significantly hinder the hydrolysis by enzymes. Here, we studied the stability and hydrolyzability of environmentally relevant metal phytate complexes (Na, Ca, Mg, Cu, Zn, Al, Fe, Al/Fe, Mn, and Cd) under different pHs, presence of metal chelators, and thermal conditions. Our results show that the order of solubility of metal phytate complexes is as follows: i) for metal species: Na, Ca, Mg > Cu, Zn, Mn, Cd > Al, Fe, ii) under d

Abstract:

ABSTRACTRaltegravir shows marked pharmacokinetic variability in patients, with gastrointestinal pH and divalent-metal binding being potential factors. We investigated raltegravir solubility, lipophilicity, pKa, and permeativityin vitroto elucidate known interactions with omeprazole, antacids, and food, all of which increase gastric pH. Solubility of raltegravir was determined at pH 1 to 8. Lipophilicity of raltegravir was determined using octanol-water partition. Raltegravir pKawas determined using UV spectroscopy. The effects of pH, metal salts, and omeprazole on the cellular permeativity of

Abstract:

CASQ (calsequestrin) is a Ca2+-buffering protein localized in the muscle SR (sarcoplasmic reticulum); however, it is unknown whether Ca2+ binding to CASQ2 is due to its location inside the SR rich in Ca2+ or due to its preference for Ca2+ over other ions. Therefore a major aim of the present study was to determine how CASQ2 selects Ca2+ over other metal ions by studying monomer folding and subsequent aggregation upon exposure to alkali (monovalent), alkaline earth (divalent) and transition (polyvalent) metals. We additionally investigated how CPVT (catecholaminergic polymorphic ventricular tac

Abstract:

The theory of thermo-emf in noncompensated polyvalent metals with a closed Fermi surface described by a weak pseudopotential is constructed under the conditions of predominance of small-angle electron–phonon scattering. The electron drag by phonons and the Umklapp processes are considered in detail. A qualitative explanation is offered for the experimentally observed significant difference in the thermo-emf in Al and In for H = 0. It is shown that the thermo-emf tensor Ŝ in a magnetic field H is determined by the competition between the two contributions ŜC and ŜU. The first of these contribut

Based on our experimental data and those obtained by researchers, mainly employees of our Institute (IHTE UB RAS), the regularities of changes in the composition of saturated vapors and the volatility of components of molten mixtures of tetrachlorides of uranium and some other metals (ThCl4, HfCl4, ZrCl4, TiCl4) with alkali metal chlorides depending on the temperature, concentration and cationic composition of melts are discussed. It is noted that the dissolution of UCl4 as well as other tetrachlorides in molten alkali metal chlorides is accompanied by complexation, manifested in a sharp decre

Abstract:

The objective of this work is to develop a novel dialysis process for the isolation of phosvitin from hen egg yolk avoiding the use of organic solvents and polyvalent metals. This bioseparation process consists of NaCl precipitation, heat treatment and dialysis, which was proposed on the basis of the property difference (especially solubility and thermostability) among yolk proteins. The native molecular mass of the purified phosvitin estimated by fast protein liquid chromatography on a Superdex 75 column was about 165 kDa.

Abstract:

Alkaline earth metal silicates as well as many polyvalent metals silicates can be obtained through aqueous solutions reactions between an alkaline silicate solution and the solutions of metal salts. The vitrifiation of the oxide compositions, established by the necessary molar ratios for the projected glass, is realised by calculating the concentration of chemical precursors, through their reaction directly on the substrate. The sodium silicate viscosity in aqueous solution and the viscosity of nitrogenated compounds or oxalates necessary in the silicates synthesis is compatible with the neces

The review focuses on how the protein, fats, carbohydrates and water interact and form the complexes during different stages of processing of instant noodles. Moisture is needed for dough formation and chemical interactions therein. Appropriate moisture content is required for proper gelatinization of noodle strand during steaming and eventually moisture is evaporatedoff by drying and frying to increase its shelf life. Frying oil may undergo degradation process invited by high frying time and temperature, high moisture in oil and polyvalent metals. Various intermediate products like dimers and
