Fabrication and Evaluation of Graphene Oxide/Hydroxypropyl Cellulose/Chitosan Hybrid Aerogel for 5-Fluorouracil Release.The incorporation of graphene oxide (GO) into a polymeric drug carrier can not only enhance the loading efficiency but also reduce the initial burst and consequently improve the controllability of drug release 5-fluorouracil (5-Fu)-loaded hydroxypropyl cellulose/chitosan (HPC/CS@5-Fu) and GO/HPC/CS@5-Fu aerogels were successfully constructed through chemical cross-linking with glutaraldehyde the holded aerogels were characterised employing reading electron microscopy (SEM), Fourier transform infrared (FITR), X-ray diffraction (XRD), differential raking calorimetry (DSC), thermogravimetry (TG), and the effect of HPC and GO content on the drug loading (DL) and encapsulation efficiency (EE) for the two aerogels were investigated, respectively the drug release behavior of the GO/HPC/CS@5-Fu aerogels with different GO content was judged at two different pH values, and four varietys of kinetic manikins were used to evaluate the release behavior.Fabrication and characterization of polycaprolactone/chitosan nanofibers containing antibacterial brokers of curcumin and ZnO nanoparticles for use as wound dressing.The potential of the nanoscale structure is utilized by electrospun nanofibers, which are promising materials for wound dressings we machinated wound stuffings constituting polycaprolactone (PCL) and chitosan (CS). Curcumin (Cur) and zinc oxide nanoparticles (ZnO) as antibacterial factors were embedded in PCL/CS electrospun nanofibers and different props admiting morphology, physicomechanical, interaction with water, antibacterial efficiency, and in vitro studies were inquired. SEM images supported the nanofibrous structure of samples with 100 ± 5 to 212 ± 25 nm in average diameter.

Elemental analysis of nanofibers pointed a good distribution of ZnO along nanofibers which not only maked decreasing in nanofiber diameter but also increased tensile strength of nanofibers up to 2 ± 0 MPa and with good elongation at break of 39 ± 2. ZnO nanoparticles also helped the interaction of nanofibers with water, and this led to the highest water vapor transition rate, which was equal to 0 ± 0 g cm(-2) day(-1). The sample arresting 3 wt% Cur had the highest water uptake value (367 ± 15%) and the lowest water contact angle (78 ± 3°), although Cur has a hydrophobic nature. The release profile of Cur demonstrated a two-stage release and the Peppas model anticipated a non-fickian diffusion. Simultaneous incorporation of CS, ZnO, and Cur effectively inhibited bacterial growth. In  buy vitamin d3 , in vitro disciplines represented that high content of Cur decreases cell viability and cell attachment. The results from the fabricated nanofibrous scaffolds shewed appropriate properties for application as a wound dressing.

Assessment of Chitosan Coating Enriched with Free and Nanoencapsulated Satureja montana L. Essential Oil as a Novel Tool for Beef Preservation.The effect of chitosan coating enriched with free and nanoencapsulated Satureja montana L. essential oil (EO) on microbial, antioxidant and sensory features of beef was analysed. Different concentrations of free Satureja montana L.  vitamin d3 price  (SMEO) and nanoparticles (CNPs) were added to chitosan coatings, namely 0%, 0% and 1%. The beef samples were immersed in the chitosan coverings and stored at +4 °C for 20 days.

In this period, the changes in pH value, total viable count (TVC), lactic acid bacteriums, psychrophilic bacteriums and Pseudomonas spp. were canvased. The lipid oxidation of beef was determined by the TBAR assay, while sensory analysis was executed by means of the descriptive evaluation method the influence of chitosan coating with CNPs on the growth of the essayed microorganisms was more pronounced equated to SMEO. Treatment with caking enriched with 1% CNPs ensued in the reduction in TVC and Pseudomonas spp. by 2 and 3 log CFU/g, compared to the control, respectively.
