Alginate hydrogels are versatile self-assembling biocompatible materials with diverse biomedical and food industrial applications, which includes uses in encapsulation, (drug) delivery tissue engineering. Hydrogel formation requires cross-linking, for alginates is often done calcium ions that engage specific interactions the polysaccharide carboxylic acid groups. Water molecules also hydrate th...

BACKGROUND This experimental study compared the hemostatic effects of calcium alginate and Anka-ferd Blood Stopper in hepatic parenchymal bleedings. MATERIAL AND METHOD The study comprised 39 male Wistar albino rats (weight 230±30 g). Laceration model was created in the left lateral lobe of the liver. Standard cotton gauze that was impregnated 0.9% NaCl solution and Calcium alginate cover was...

The purpose of this study was to investigate the influence of different hydrophilic polymers on the swelling, bioadhesion and mechanical strength of hydrocolloid wound dressings (HCDs) in order to provide an appropriate composition for a hydrocolloid wound dressing system. In this study, the HCDs were prepared with styrene-isoprene-styrene copolymer (SIS) and polyisobutylene (PIB) as the base u...

in atom transfer radical polymerization (atrp) of methyl acrylate (ma) with polyvinyl acetate macroinitiator in bulk at 90°c the plots of ln [m]0/[m] increased linearly with reaction time. the apparent propagation rate constant (kp app) of the reaction was obtained from the linear curve and used to calculate the free macroradical concentration ([r°]) in polymerization medium. the [r°] and also ...

radiation degradation of chitosan is one of the most important methods to prepare antibacterial oligochitosans. in this study, the effect of solvent on the reduction of degradation dose and enhancement of the antibacterialactivity of chitosan against pectobacterium carotovorum (pc) has been considered.gamma radiation degradation was applied to chitosan as solid and aqueous solution at dose rang...

background: this study was designed to examine a unique and low dose use of intravenous enoxaparin in elective percutaneous coronary intervention (pci) that would be applicable to an unselected population regardless of age, weight, and renal function. there is limited experience in anticoagulation using intravenous low-molecular-weight heparin in pci. methods: a total of 100 consecutive patient...

Polysaccharides and their inherent structural and chemical variability provide an enormous hitherto unexploited design space for production of a range of new biobased materials. Exopolysaccharides are synthesized by numerous microorganisms (Rehm, 2010). Studies on biosynthesis provided critical information on how precursors are enzymatically diverted from primary metabolites and how they are po...
