It was more than 50 years ago that an appearance of birefringence in alginate gels prepared under cation flow reported for the first time, however, anisotropic structure gel has not been studied detail. In present study, Ca-alginate were within dialysis tubing a high Ca2+-concentration external bath, and optical small-angle X-ray scattering (SAXS) measurements performed to characterize gel. The observations with crossed polarizers circular revealed molecular orientation perpendicular...
Addition of sugars such as sucrose to aqueous protein solutions generally stabilizes proteins against thermal denaturation by preferential exclusion from (preferential hydration proteins). In this study, we investigated the effect sucralose, a chlorinated derivative, on stability and solvation. Circular dichroism small-angle X-ray scattering measurements showed that increased temperature myoglobin was preferentially excluded protein, whereas sucralose decreased adsorbed protein. No clear...
The effect of an erythromycin derivative, EM-523, on gastrointestinal motility was investigated in conscious dogs and compared with that motilin cisapride, trimebutine metoclopramide. In the fasting state, EM-523 given i.v. or i.d. at 3 micrograms/kg more induced contractions stomach migrated along small intestine. pattern very similar to by motilin. digestive increased amplitude gastric contractions. Cisapride metoclopramide both states; however, their contractile different from EM-523....
We have found that dialysis of 5 mg/mL collagen solution into the phosphate with a pH 7.1 and an ionic strength 151 mM [corrected] at 25 °C results in gel birefringence tubular pores aligned parallel to growth direction gel. The time course averaged diameter during anisotropic gelation was expressed by power law exponent 1/3, suggesting formation is attributed spinodal decomposition-like phase separation. Small angle light scattering patterns high resolution confocal laser scanning...
Reversible chain association/dissociation phenomenon viaCO2 responsive crosslinking/decrosslinking was detected in aqueous solutions of polyallylamine (PAA). The behavior reversible and useful the synthesis porous crosslinked polystyrene, which suggested potential utility area CO2-responsive separable adhesives, switches sensors.
Pandemic simulation is considered to be crucial as a scenario and it performed by many kinds of methods, the classical ordinary differential models (SIR model), agent-based models, internet-based etc are among them. The SIR model one fundamental methods see behavior pandemic with easy computation. However, there no stochastic variation in equations. equations (SDE) can provide such kind variations. Although SDE applied fields economics, less attention has been paid simulations. In this...
Knowledge of the conformations a water-soluble protein bound to membrane is important for understanding membrane-interaction mechanisms and membrane-mediated functions protein. In this study we applied vacuum-ultraviolet circular-dichroism (VUVCD) linear-dichroism (LD) spectroscopy analyze α-lactalbumin (LA), thioredoxin (Trx), β-lactoglobulin (LG) phosphatidylglycerol liposomes. The VUVCD analysis coupled with neural-network showed that these three proteins have characteristic helix-rich...
Abstract Poly( N ‐isopropylacrylamide‐ co ‐hydroxyethyl methacrylate) [P(NIPAM‐ ‐HEMA)] copolymer was synthesized by controlled radical polymerization from respective ‐isopropylacrylamide (NIPAM) and hydroxyethyl methacrylate (HEMA) monomers with a predetermined ratio. To prepare the thermosensitive biodegradable nanoparticles, new graft copolymer, poly( L ‐lactide)‐ ‐poly( ‐isoporylacrylamide‐ [PLLA‐ g ‐P(NIPAM‐ ‐HEMA)], lower critical solution temperature (LCST) near normal body...
We study the friction behaviors of poly(vinyl alcohol) (PVA) gel sliding against glass surface in dilute poly(ethylene oxide) (PEO) aqueous solution with various molecular weights, Mw, and concentrations. At low velocity (10-5, 10-4 m/s), distinct PEO polymer effects are observed: The frictional stress 2E4 (Mw = 2 × 104 g/mol) solutions is lower than that pure water, decreasing increase concentration reaching a minimum at crossover concentration, c*. However, higher weight solution, 4E6 4...
