TL;DR: The present review focuses on the recent advances in drug delivery applications of chitosan-based PEC with other natural polysaccharides, including alginate, hyaluronic acid, pectin, carrageenan, xanthan gum, gellan gum, gum arabic, and carboxymethyl cellulose.

TL;DR: This review will present the current situation with respect to gelatin usage as a packaging source material and the challenges that remain in order to move the manufacture of gelatin-based films nearer to commercial reality.

TL;DR: Chitin and chitosan characteristics were depending upon the chitin source, and α-chitins were more crystalline polymorph than β-chITin.

TL;DR: G gelatin and G75/C25 films demonstrated a high antioxidant activities monitored by β-carotene bleaching, DPPH radical-scavenging and reducing power activities, while films contained chitosan exhibited higher antimicrobial activity against Gram-positive than Gram-negative bacteria.

TL;DR: Production, processing, composition, properties, food applications and health benefits of locust bean gum are focused on.

TL;DR: The results suggested that the c-EPS produced by L. plantarum 70810 might be suitable for use as functional foods and natural antitumor drugs.

TL;DR: The aim of the present review is to summarize previous and current references and give a comprehensive summary regarding the structural features and biological activities of A. membranaceus polysaccharides in order to provide new insight for further development of these macromolecules.

TL;DR: It was found that luteolin reversibly inhibited α-glucosidase in a noncompetitive manner with an IC50 value of (1.72 ± 0.05) × 10(-4) mol L(-1), and the inhibition followed a multi-phase kinetic process with a first-order reaction.

TL;DR: The results of potent healing using fabrics treated with 250 ppm AgNPs indicate that it leads to similar results compared with that of the Dermazin cream, and the anti-inflammatory effect AgNps is nearly similar to 20 ml dose of the reference indomethacin drug.

TL;DR: It was concluded that the branched structure of GA was a significant factor for the functionality of GA-SeNPs and its efficiency in stabilizing SeNPs was compared with GA.

TL;DR: Results showed that both chitosans inhibited the growth of most Gram-negative, Gram-positive bacteria and fungi tested and exhibited antioxidant and antitumor activities which was dependent on the molecular weight.

TL;DR: The antibacterial activity of the prepared chitosan nanocomposites films was evaluated against gram positive and gram negative bacteria, fungi, fungi and yeast and can be potential used as antimicrobial agents in packaging applications.

TL;DR: In vitro methyl thiazolyl tetrazolium (MTT) assays demonstrated that the chitosan/sericin composite nanofibers were biocompatible and could promote the cell proliferation and show good bactericidal activity against both of Gram-positive and Gram-negative bacteria.

TL;DR: The results that vitamin B2-loaded nanoparticles are more stable (in terms of size and PDI) than nanoparticles without vitamin B1 and 2.2±0.6%, respectively are shown.

TL;DR: The kinetics of adsorption of MG onto Alg-Fe3O4 nanoparticles were investigated using the pseudo-first-order and pseudo-second-order kinetic models and the results showed that the adsorbent dosage, pH and temperature were investigated on the advertisersorption properties of MG.

TL;DR: The results of in vitro MTT assay carried out on SKC01 colon carcinoma corroborate the observed DNA interactions and confirms the importance of unmodified daunosamine amino group for optimal interactions with DNA.

TL;DR: In this paper, a casting method was used to prepare potato starch based bio-nanocomposite films with halloysite nanoclay as the reinforcing materials, which improved the barrier and mechanical properties of potato starch films.

TL;DR: The results suggested that there were significant differences in hypoglycemic and antioxidative activities between four Dendrobium polysaccharides, which may be contributed to their physicochemical properties.

TL;DR: The results suggest that the carrageenan-based composite films have a high potential for being used as an antimicrobial or active food packaging applications.

TL;DR: Results showed that the water vapor permeability (WVP) and water solubility (WS) of the agar-based nanocomposite films significantly decreased about 13% and 21%, respectively, upon increasing the NCC content to 10%.

TL;DR: Antimicrobial activity of all the films increased against both Gram positive and Gram negative bacteria as percentage of Betel leaf extract increased, except for Psuedomonas aeruginosa, which was not susceptible at any percentage of the extract.

TL;DR: This study showed that B. xenovorans LB400 synthesize PHAs under nutrient limitation, and indicated the presence of pha genes encoding enzymes of pathways for PHA synthesis.

TL;DR: Administration of the chitosan derivatives could significantly increase antioxidant enzymes activities and decrease malondialdehyde levels in both serums and livers of d-galactose induced aging mice.

TL;DR: The study suggests that magnetic graphene/chitosan nanocomposite is a promising nano adsorbent for removal of anionic azo dyes from aqueous solution.

TL;DR: Biodegradable kefiran-whey protein isolate-titanium dioxide blend films were developed and characterized as a function of incorporating amount of TiO2 nanoparticles, showing that the water vapor permeability, moisture content, moisture absorption and water solubility decreased by increasing the nano-TiO2 content.

TL;DR: This review is primarily focused on the microbial production, purification, recovery, and the characterization based on the available published literature on the welan gum.

TL;DR: An overview of biological activities and potential health benefits of PCP and their derivatives is presented.

TL;DR: The adsorption of arsenic ions was observed to follow pseudo-second order mechanism as well as the thermodynamic parameters confirm also the endothermic spontaneous and a physisorption process.

TL;DR: The obtained results indicated that the impregnation of the room temperature IL significantly enhances the removal efficiency of Cr(VI) and may be suitable materials in heavy metal ion pollution cleanup if they are synthesized in large scale and at low price in near future.

TL;DR: Response surface methodology (RSM) was applied to optimize the parameters of pectin extraction from okra pods and the extracted okra pectIn showed predominantly viscous responses (G'), which could be well described by the Cross model.
