Smooth microsomal cell membranes were isolated by density gradient centrifugation from normal rat liver and from the well-differentiated Morris hepatoma 5123C. The proteins were then extracted from the smooth membrane fraction and compared on acrylamide gel by the split-gel technique and by coelectrophoresis of dually labeled proteins. This analysis revealed the lack of two liver membrane compo...

PURPOSE The mechanism of axial elongation in the myopic eyeball remains to be elucidated. It is known that the expression profile for some proteins in the aqueous humor (AH) changes in some diseases. Accordingly, determinations of these AH proteins may serve to understand their potential role in this pathogenesis. To identify the possible mechanism in myopia development, a proteomic analysis of...

The acute phase reactant serum amyloid A protein (SAA) circulates in plasma as a constituent of high density lipoproteins (HDL). Advantage has been taken of the induction of SAA in human subjects with myocardial infarction to study the effect of SAA on the physical and chemical properties of HDL. HDL were isolated by sequential ultracentrifugation and assayed for chemical composition. Apolipopr...

The article is devoted to the issue of a low sweep efficiency in heterogeneous terrigenous reservoirs containing remaining oil. Water plugging operations that redirect injection fluid flows into unswept zones, are one approach enhancing oil recovery these reservoirs. commonly used chemical reagents treatments acrylate polymer solutions. solutions must reach target water-saturated zones and form...

in this work, sol-gel processing was used to synthesize the fluorohydroxyapatite (nano-fha, ca10(po4)6(oh)2−xfx) nanopowders. the advantages of the sol-gel method over other methods are precise control of composition, low processing temperature, and better homogeneity. calcium nitrate tetrahydrate, phosphorous pentoxide and tetrabuthylammonium fluoride were used, respectively, as p, ca, and f p...

Abstract The effects of various material compositions and reservoir environments on the ultimate strength swelling kinetics a commercial preformed particle gel (PPG) have been investigated. This study used different ratios acrylamide acrylic acid copolymers with specific crosslinker concentration. Results indicated that increasing proportion enhances PPGs’ ability to swell but weakens their net...

It was found that simple AIE compounds could emit different intensity of fluorescence in gel, suspension and precipitates for the first time, which could be applied to fluorescence switches and quantitative determination of enantiomer composition.

Topicality. Bedsores are an urgent problem of modern medicine both at the outpatient and inpatient stage. For treatment infected bedsores it is advisable to use drugs that have a complex effect focused on various parts pathological process. chronic wounds together with inhibition growth microorganisms drug must provide optimal conditions for granulation, reparative anti-inflammatory effect. Aim...

Naphthalenediimide appended peptide based self-assembly was studied. Interestingly, an aggregation induced drastic change in the fluorescence property and gel formation were observed depending on the solvent composition (chloroform : methylcyclohexane) at a fixed concentration of 1.6 mM at room temperature.

Multiple criteria must be used to relate a membrane fraction (;myelin-like') to myelin. These reported in this communication are electron microscopy, marker enzymes, sodium dodecyl sulphate-polyacrylamide-gel electrophoretic patterns and lipid composition.
