Physicochemical characteristics of quinupramine in the EVA matrix

International Journal of Pharmaceutics, 2006
Ethylene-vinyl acetate (EVA) is widely used as a membrane or matrix for transdermal drug delivery systems. In an attempt to determine the state of a drug in the EVA matrix, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and thermal analysis of the quinupramine-EVA matrix were carried out and the results were compared with ...

Biocompatibility and physicochemical characteristics of alginate–polycation microcapsules

Acta Biomaterialia, 2011
There is a need for better understanding of the biocompatibility of alginate-polycation microcapsules based on their physicochemical characteristics. Microcapsules composed of alginate with 44% (IntG) or 71% (HiG) guluronate, gelled with calcium (Ca) or barium (Ba) and coated with poly-L-lysine (PLL) or poly-l-ornithine (PLO), followed by IntG alginate

Modeling of physicochemical characteristics of alkanes

Russian Chemical Bulletin, 2005
A new type of descriptors is considered, which allows for actual molecular structure in contrast to topological indices. In order to calculate these descriptors, a total of about 600, 000 alkane conformational isomers up to C16H34 were analyzed. Using the new descriptors, the densities, molar volumes, and the boiling and melting points of alkanes were ...

Physicochemical characteristics of powder boronizing

Soviet Powder Metallurgy and Metal Ceramics, 1979
1. According to thermodynamic calculations, in the initial stage boronizing may occur through a dual mechanism: simultaneous active diffusion of atomic boron and direct reaction resulting in the formation of higher iron borides. 2. It is demonstrated that in powder boronizing the nature of the activator has a pronounced effect on the ...

Physicochemical Characteristics of Biopolymers

1986
In recent years, chemists, biochemists and biologists have developed a growing concern for understanding the pathways along which metals are involved in biological systems (1–3). The “no man’s land” between inorganic chemistry and biological sciences has thus developed into a discipline by itself, the inorganic biochemistry.

The physicochemical characteristics of oxidized polysaccharides

Russian Journal of Physical Chemistry B, 2009
The paper presents the results obtained in studies of the physicochemical characteristics of modified polysaccharides prepared by the catalytic oxidation of starch with molecular oxygen in an alkaline medium. The amorphous-crystalline structure of starch was partially retained after oxidation.

PHYSICOCHEMICAL CHARACTERISTICS OF YAM STARCHES

Journal of Food Biochemistry, 1981
Starch from tubers of Dioscorea alata, Dioscorea cayenensis, Dioscorea dumetorum, and Dioscorea rotundata was isolated and some of the important characteristics determined. Amylose and amylopectin fractions were obtained by aqueous leaching technique. All the starches appeared to have definite but minor differences in iodine binding capacity, swelling ...

Physicochemical characteristics of flaxseed gum

Food Research International, 1996
Hydrocolloidal gums extracted from four flaxseed cultivars were characterized in terms of loss of weight on drying, ash and nitrogen contents, mineral and amino acid compositions and intrinsic viscosity. Monosaccharide composition, galacturonic acid content and 13C NMR spectra provided further structural information on the polysaccharide gums ...

Hepatic stimulator substance: physicochemical characteristics and specificity

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1982
This laboratory has reported previously that a cytoplasmic extract of weanling or regenerating adult rat liver (but not normal rat liver) will produce a 2.5-fold increase in the incorporation of tritiated thymidine ([3H]dThd) into liver DNA of a 34%-hepatectomized test animal. (J. Physiol. London 248: 273-284, 1975).

Opsonic and Physicochemical Characteristics of Intravenous Immunoglobulin Preparations

Vox Sanguinis, 1987
Abstract. The composition and opsonizing activity of five commercially available immunoglobulin preparations for intravenous use (Venoglobulin I, Venilon, Gammagard, Polyglobin, and Sandoglobulin) were studied. The composition of these preparations does not differ very much as far as total protein, immunoglobulin class and IgG subclass concentrations ...
