TL;DR: Biological activities of peptides from marine organisms are presented, emphasizing their potential applications in foods as well as pharmaceutical areas.

TL;DR: Developed calcium alginate/gum Arabic beads containing glibenclamide could possibly be advantageous in terms of advanced patient compliance with reduced dosing interval and increase in drug encapsulation efficiency and decrease in drug release were found.

TL;DR: A novel nano-adsorbent, β-cyclodextrin-chitosan (CDC) modified Fe(3)O(4) nanoparticles (CDCM) is fabricated for removal of methyl blue from aqueous solution by grafting CDC onto the magnetite surface and the adsorption capacity was about 90% of the initial saturation adsorptive capacity after being used four times.

TL;DR: The results suggest that the porous starch has a more excellent adsorption capacity than the native starch, and may be expected to have wide potential applications in many fields.

TL;DR: Because SQChN has the highest aspect ratio, its 0.1% dispersion had the highest shear stress and viscosity at the same shear rate in the four chitin nano-samples, and showed gel-like behavior in the wholeShear rate range from 10(-3) to 10(3) s(-1).

TL;DR: Tannic acid exhibited the highest cross-linking ability on myofibrillar protein as evidenced by higher decrease in free amino groups with coincidentally lower band intensity of myosin heavy chain (MHC).

TL;DR: The maximum theoretical adsorption capacities of the CSTG resin for Hg(2+), Cu (2+) and Zn(2+) were found to be 98±2, 76±1 and 52±1 mg g(-1), respectively, while the negative values of Gibbs free energy of adsorptive indicated the spontaneity of the adsor adaptation of all metal ions on the novel resin.

TL;DR: The developed CS/nHAp/nCu-Zn scaffolds have advantageous and potential applications over the CS- nHAp scaffolds for bone tissue engineering.

TL;DR: Biocompatible, 200 nm sized tetracycline encapsulated O-carboxymethyl chitosan nanoparticles (Tet-O-CMC Nps) via ionic gelation is developed for its sustained delivery of Tet into cells proving it to be an efficient nanomedicine to treat intracellular S. aureus infections.

TL;DR: The results suggest that the nano-insulin-loaded hydrogels are a promising non-invasive TDD system for diabetes chemotherapy.

TL;DR: In the current work chitosan was extracted from shrimp shells and then used as antibacterial exhaust finishing agent for grafted bamboo rayon and showed antibacterial activity against both types of bacterias which was durable till 30 washes.

TL;DR: RRPP may be responsible for the pharmacological effect of anti-fatigue of Radix Rehmanniae Preparata, the mechanism was related to the increase of the storage of hepatic glycogen and the decrease of the accumulation of SUN and BLA.

TL;DR: Excellent interconnected porosity, controlled biodegradation and enhanced cell proliferation of the novel chitosan-CS/HAp and chitOSan-AP-HAp scaffolds suggests that these scaffolds are promising biomaterials for bone tissue engineering.

TL;DR: The prospective results allow the particles to be employed as site-specific HP controlled release system by tuning the CHT/TPP molar ratio.

TL;DR: An implantation experiment in mouse skulls revealed that the composite scaffold provides a strong positive effect on bone formation in vivo in mice and has been shown to be more effective for new bone generation than chitosan-alginate scaffold.

TL;DR: The results showed that LEPC1 exhibited significantly antioxidant activity at a concentration-dependent manner, indicating that the water-extractable polysaccharide fraction was a potent antioxidant and could be developed to be new health medicine for fighting against various human diseases.

TL;DR: Cultures conducted in media containing shrimp shell waste supplemented with 5% (w/v) glucose were found to remarkably promote demineralization efficiency, without affecting deproteinization rates.
