The consumption of diapers and sanitary products has constantly been rising. Several problems are associated with using chemical-based products, which difficult to degrade easily cause nappy rash bacterial infections in babies. Therefore, there is an increasing shift towards natural-based because their biodegradability, non-toxicity, biocompatibility. studies being carried out researchers have ...

Background: Alginate materials have been widely employed for biomedical applications ranging from wound healing to cancer treatment. However, how alginate materials affect the immune system is largely unknown. Objective: To explore the impact of alginate materials on immune system. Methods: The effect of three types of alginate materials, low viscosity, high viscosity and particulate alginate, ...

Sphingomonas sp. strain A1, a Gram-negative bacterium, directly incorporates alginate polysaccharide into the cytoplasm through a periplasmic alginate-binding protein-dependent ATP-binding cassette transporter. The polysaccharide is degraded to monosaccharides via the formation of oligosaccharides by endo- and exotype alginate lyases. The strain A1 proteins for alginate uptake and degradation a...

OBJECTIVES Pseudomonas aeruginosa is a Gram-negative and aerobic rod bacterium that displays mucoid and non-mucoid phenotype. Mucoid strains secrete alginate, which is the main agent of biofilms in chronic P. aeruginosa infections, show high resistance to antibiotics; consequently, the biological disruption of mucoid P. aeruginosa biofilms is an attractive area of study for researchers. Alginat...

Enzymes have a wide variety of applications in diverse biotechnological fields, and the immobilization of enzymes plays a key role in academic research or industrialization due to the stabilization and recyclability it confers. In this study, we immobilized the Brassica oleracea chlorophyllase 1 (BoCLH1) or Candida rugosa lipase (CRL) in magnetic iron oxide nanoparticles-loaded alginate composi...

This review compiles information regarding the use of alginate, and in particular alginate hydrogels, in culturing cells in 3D. Knowledge of alginate chemical structure and functionality are shown to be important parameters in design of alginate-based matrices for cell culture. Gel elasticity as well as hydrogel stability can be impacted by the type of alginate used, its concentration, the choi...

BACKGROUND Expansion and differentiation of stem cells relies on the soluble materials as well as the physical conditions of their microenvironment. Several methods have been studied in attempt to enhance the growth and differentiation rates of different adult stem cells extracted from different sources. OBJECTIVES The purpose was to improve the three-dimensional (3D) culture condition of the...

Core-shell alginate-poly (lactic-co-glycolic) acid (PLGA) microparticles are potential candidates to improve hydrophilic drug loading while facilitating controlled release. This report studies the influence of the alginate core size on the drug release profile of alginate-PLGA microparticles and its size. Microparticles are synthesized through double-emulsion fabrication via a concurrent ionotr...

Background & Aims: Chronic pulmonary infection in patients with cystic fibrosis is predominantly due to infection by mucoid strains of Pseudomonas aeruginosa. Mucoid P. aeruginosa is due to the production of exopolysaccharide called also alginate. Alginate in addition to interference with the clearance of lung has antiphagocytic property. Optimal killing activity of P. aeruginosa requires opson...

This is the “mobile” era, characterized by a growing demand of flexible substrates for novel products such as curved screens, folding smartphones, and wearable devices. In this framework, plastic electronics represents suitable technology to replace silicon-based electronics. However, up now, little attention has been devoted rendering more environmentally sustainable. It thus necessary develop...
