OBJECTIVES (1) To show that extracellular matrix deposition in 3-dimensional culture of human septal chondrocytes cultured in a rotary bioreactor is comparable to the deposition achieved under static culture conditions. (2) To demonstrate that the biomechanical properties of human septal chondrocytes cultured in a bioreactor are enhanced with time and are analogous to beads cultured under stati...

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...

Background: Biosurfactants are derived from microbes, plants, and animals. Acinetobacter junii B6 is a lipopeptide biosurfactant producer previously investigated for its structure, physicochemical, product aggregation properties. Objectives: In this study, we optimized the bioencapsulation of A. in calcium alginate hydrogel. Methods: was encapsulated using The formulation hydrogel full factoria...

Abstract The bottleneck for the production of biofuels from microalgae consists on costly harvesting processes and low lipid production, immobilization technology could play a part making more feasible. aim this study was to evaluate effect alginate growth productivity Chlorella sorokiniana , so far, main focus has been its use wastewater treatment nutrient removal effluents. cultured in both f...

A simple technique for high-throughput protein crystallization in ionically cross-linked polysaccharide gel beads has been developed for contactless handling of crystals in X-ray crystallography. The method is designed to reduce mechanical damage to crystals caused by physical contact between crystal and mount tool and by osmotic shock during various manipulations including cryoprotection, heav...

Calcium-induced alginate gel bead (Alg-Ca) coated with an alginate hydrolysate (Alg), e.g. the guluronic acid block (GB) was prepared and the model drug, hydrocortisone release profiles were investigated under simulated gastrointestinal conditions. Their molecular weights were one sixth or one tenth that of Alg and the diffraction patterns of the hydrolysates resembled that of Alg. The drug rel...

This paper describes preparation and characterization of beads of alginate and psyllium containing probiotic bacteria of Lactobacillus acidophilus DMSZ20079. Twelve different formulations containing alginate (ALG) and alginate-psyllium (ALG-PSL) were prepared using extrusion technique. The prepared beads were characterized in terms of size, morphology and surface properties, encapsulation effic...
