TL;DR: The results suggest that SA/PVA/ZnO mats could be an ideal biomaterial for wound dressing applications once the optimal concentration of ZnO which will give least toxicity while providing maximum antibacterial activity is identified.

TL;DR: Procyanidin stabilizes collagen as a cross-linker and preserves its triple helical structure under acidic conditions, and differential scanning calorimetry and thermogravimetric measurements reveal that the collagen/procyanodin films have improved thermal stability in comparison with pure collagen.

TL;DR: Results suggested that CS/nHAp/nAg bio-composite scaffolds have the potential in controlling implant associated bacterial infection during reconstructive surgery of bone.

TL;DR: The BCNC obtained through cellulose treatment under controlled conditions were associated with several desirable properties and appear to be superior over the conventional methods of nanocrystals production.

TL;DR: This review paper provides the recent development on chitosan derivatives available for gene delivery and its applications including the interaction and intracellular delivery of genetic materials.

TL;DR: Significant indications that crude fucoidan exerts bioactive effects on lung and skin cancer model cells in vitro and induces enhanced natural killer cell activity in mice in vivo are provided.

TL;DR: The newly developed TSP-alginate composite beads are suitable for controlled delivery of diclofenac sodium for prolonged period and their observed responses were coincided well with the predicted values by the experimental design.

TL;DR: It is concluded that guar gum and its derivatives in the various forms such as coatings, matrix tablets, hydrogels and nano/microparticles can be exploited as potential carriers for targeted drug delivery.

TL;DR: By increasing of OA content, the cloudiness of the CMC films was intensified and Hunter value of the films increased (by ca. 35.8%).

TL;DR: In vitro and in vivo results suggest that the sulfated polysaccharides are strong immunostimulating activities and that Th-1 cells might be the main target cells of the F(2) fraction.

TL;DR: In this work, porous scaffolds obtained from the freeze-drying of pectin/chitosan polyelectrolyte complexes were prepared and characterized by FTIR, SEM and weight loss studies, and it was confirmed that the degradation by-products of pectorine/ch itosan scaffold are noncytotoxic.

TL;DR: The developed chitin-chitosan/nano TiO(2) composite scaffold showed controlled swelling and degradation when compared to the control scaffold and it can be used for tissue engineering applications.

TL;DR: The adsorption kinetics followed the mechanism of the pseudo-second order equation for all systems studied, evidencing chemical sorption as the rate-limiting step of adsorptive mechanism and not involving a mass transfer in solution.

TL;DR: Polyacrylamide grafted starch was made by a novel method of synthesis, involving combination of microwave radiation and a chemical free radical initiator (ceric ammonium nitrate) to initiate grafting reaction.

TL;DR: Results indicated that TRC-NPs could be a potential nanovehicle for curcumin drug delivery.

TL;DR: Results indicate that CS/PCL nanofibrous scaffold would be an excellent system for bone and skin tissue engineering.

TL;DR: The results suggested the potential utilization of CS-g-PCL/PCL (2/8) nanofibrous mats for skin tissue engineering with moderate surface zeta-potential for cell attachment and proliferation.

TL;DR: It is found that the conformation of SF contained in PCL/SF composite nanofibers was transformed from random coil to β-sheet when treated with methanol, leading to improved crystallinity and tensile strength of nan ofibrous scaffolds.

TL;DR: Wautersia eutropha was able to synthesize medium chain length polyhydroxyalkanoates (PHAs) when canola oil was used as carbon source.

TL;DR: It was found that the porous structure of scaffolds can be tailored by varying the ratios of gelatin to HA, both the swelling ratios and degradation rate increased with the increase of HA content in hybrid scaffolds, and crosslinking the scaffolds with EDC improved the degradation resistance of the scaffold in culture media and increased the mechanical strength of scaffold.

TL;DR: Different Andean crops were used to obtain starches not previously reported in literature as raw material for the production of biodegradable polymers and the results show that the mechanical properties of starch based films strongly depend on the starch source used for their production.

TL;DR: ZnO-NP bound β galactosidase may find its applications in constructing enzyme-based analytical devices for clinical, environmental and food technology and in view of its easy production, improved stability against various denaturants and excellent reusability.

TL;DR: It was showed that lignin is most sensitive component to the photodegradation processes as indicated by considerable decreases in the intensities of the characteristic aromatic lign in band at 1505cm(-1) and other associated bands.

TL;DR: A suitable mechanism for copper sorption was established and the selectivity of the metal ions for the composites was identified.

TL;DR: The antioxidant activity of CMAAP22 was improved, nearly twice as much as that of the AAP, especially in the scavenging of DPPH and ABTS+.

TL;DR: The purified Aloe protein exhibited a potent anti-fungal activity against Candida paraprilosis, Candida krusei and Candida albicans and showed an anti-inflammatory property against pure lipoxygenase and cyclooxygenases-2.

TL;DR: A comparative study between the performance of two different crosslinkers, genipin (GP) and γ-glycidoxypropyltrimethoxysilane (GPTMS), is presented, finding that GP and GPTMS increased the stability of G in aqueous media and improved the mechanical properties.

TL;DR: The present study demonstrated that the peptides derived from Pacific cod (G. macrocephalus) skin gelatin could be used in the food industry as functional ingredients with potent antioxidative and antihypertensive benefits.

TL;DR: New edible composite films based on kefiran and oleic acid at the ratio of 15, 25, and 35% (w/w) were prepared using emulsification with the aim of improving their water vapour barrier and mechanical properties.

TL;DR: It is confirmed that the degradation by-products of sodium hyaluronate/chitosan scaffold are noncytotoxic, which is fundamental for its application in the biomedical field.
