Low-cost decorated sodium alginate beads with polyaniline (Alg@PANI beads) were easily prepared using a cross-linking method, and employed for the adsorption of Cr(VI) from aqueous solutions. The effect several influencing parameters, including temperature, contact time, concentration, adsorbent dosage, was investigated optimized central composite design (CCD) under response surface methodology...

Spinal cord injury (SCI) has been implicated in neural cell loss and consequently functional motor and sensory impairment. In this study, we propose an alginate-based neurobridge enriched with/without trophic growth factors (GFs) that can be utilized as a therapeutic approach for spinal cord repair. The bioavailability of key GFs, such as Epidermal Growth factor (EGF) and basic Fibroblast Growt...

Chitosan-alginate (CS/ALG) nanoparticles were prepared by ionotropic pre-gelation of an alginate core followed by chitosan polyelectrolyte complexation, nifedipine was chosen as a model drug. Morphology and structure characterization of nanoparticles were investigated by transmission electron microscope (TEM) and Fourier transform infrared spectra (FTIR), respectively. The diameter of the nanop...

An alginate gel bead composite adsorbent with polyethyleneimine (PEI) as a surface modifier and Eichhornia crassipes (EC) biochar, known EC-alg/PEI-3, was added internally to the adsorb Cr(VI) from an aqueous environment. The functionalized beads were characterized using SEM, XPS, FTIR, other techniques. maximum adsorption capacities of EC-alg/PEI-3 714.3 mg g?1 at 10 °C 769.2 25 °C. In treatme...

BACKGROUND AND OBJECTIVES Treatment of Pseudomonas aeruginosa infections is greatly hampered by innate and acquired antibiotic resistance. The goal of this study was to compure the immunogenicity of conjugates of P. aeruginosa depolymerized alginate-diphtheria toxoid (D-ALGDT) and P. aeruginosa detoxified lipopolysaccharidediphtheria toxoid (D-LPSDT) in mouse model. MATERIALS AND METHODS Algi...

Abstract Oncolytic adenoviruses (OAs)‐based virotherapy can regulate the tumor microenvironment, providing a rational strategy for combination treatment with other therapy techniques, such as transcatheter arterial embolization (TAE). Here, novel, validated viroembolization (TAVE) strategy—a calcium alginate hydrogel microsphere OA encapsulated (OA@Alg beads) to achieve of TAE oncolytic enhance...

This study reports for the first time effect of particle size bioactive glass 46S6 on physico-chemical and mechanical properties carbonated apatite cement (CPC) composed brushite (CaHPO4. H2O) vaterite (CaCO3). Three ranges were investigated: coarse (BGc: 100–200 ?m), medium (BGm: 40–100 fine (BGf<40 ?m). For composite formulations, three liquid phases used: distilled water as a simple setting ...

Fibers composed of polysaccharides are a promising candidate to be applied for biomaterials such as absorbable surgical sutures, textile fabrics, and hierarchical three-dimensional scaffolds. In this work, in order fabricate biocompatible fibers with controlled-release abilities, the fabrication coaxial calcium alginate (ALG-Ca) polyion complexes (PICs) consisting chitosan (CHI) chondroitin sul...

Cellulose nanocrystals (CNC) were prepared by formic acid hydrolysis and TEMPO- (2,2,6,6-tetramethyl-piperidine-1-oxyl-) mediated oxidation. The CNCs reinforced into biopolymers chitosan (CHI), alginate (ALG), gelatin (GEL) to obtain “CNC-ALG-GEL” “CNC-CHI-GEL” hydrogels. synthesized hydrogels characterized for physicochemical, thermal, structural characterization using Fourier transform infrar...

A bioactive grape pomace extract (GPE) rich in polyphenols was encapsulated into alginate (GPE-Alg) or chitosan (GPE-CS) microparticles, later incorporated coconut water. Biological and sensory properties were evaluated. Storage performed at 4 ˚C followed by quality assessment. Evaluation of water after gastrointestinal digestion on the growth pathogens probiotic bacteria showed that fortificat...
