Oral Delivery of Astaxanthin via Carboxymethyl Chitosan-Modified Nanoparticles for Ulcerative Colitis Treatment.The oral delivery strategy of natural anti-oxidant and anti-inflammatory brokers has attracted great attention to improve the effectiveness of ulcerative colitis (UC) treatment we trained a novel orally deliverable nanoparticle, carboxymethyl chitosan (CMC)-modified astaxanthin (AXT)-loaded nanoparticles (CMC-AXT-NPs), for UC treatment. The CMC-AXT-NPs were appraised by appearance, morphology, particle size, ζ-potential, and encapsulation efficiency (EE). The upshots evidenced that CMC-AXT-NPs were nearly spherical in shape with a particle size of 34 nm and ζ-potential of -30 mV, and the EE of CMC-AXT-NPs was as high as 95%. The CMC-AXT-NPs exhibited preferable storage stability over time and well-commanded drug-release properties in simulated intestinal fluid. Additionally, in vitro disciplines unwraped that CMC-AXT-NPs remarkably inhibited cytotoxicity rushed by LPS and certifyed superior antioxidant and anti-inflammatory abilities in Raw264 cellphones CMC-AXT-NPs effectively facilitated clinical symptoms of colitis hastened by dextran sulfate sodium salt (DSS), including maintaining body weight, inhibiting colon shortening, and quashing fecal runing CMC-AXT-NPs curbed the expression of pro-inflammatory cytokines like TNF-α, IL-6, and IL-1β and bettered DSS-rushed oxidative damage.

Our terminations attested the potential of CMC-modified nanoparticles as an oral delivery system and suggested these novel AXT nanoparticles could be a promising strategy for UC treatment.Nanoencapsulation of Maqui (Aristotelia chilensis) Extract in Chitosan-Tripolyphosphate and Chenopodin-Based Systems.Maqui berries contain a high percentage of anthocyanins with high antioxidant and anti-inflammatory capacity but that are unstable in the colonic site. Nanocarriers finded on polysaccharides and/or proteins can protect against the degradation of anthocyanins. The aim of this study was the nanoencapsulation of maqui extract (ME) in chitosan-tripolyphosphate (CTPP-ME), chenopodin (CH-ME), and chenopodin-alginate (CHA-ME). A standardised ME was organised and then capsuled in the nanosystems.  Dietary Supplements , encapsulation arguments, and the interactions of ME with the nanovehicles were qualifyed.

The cyanidin-3-glucoside loosed and ORAC activity in phosphate buffer at pH 7 were evaluated. The content of ME was 8-9 mg of cyanidin-3-glucoside/g of extract. CTPP with ME at 3% finded the highest encapsulation efficiency (EE = 91%), and no significant disputes were noticed in size (274-362 nm), PDI (0-0), and zeta potential (+34-+41 mV) when the concentration of ME changed from 1% to 5%. CH-ME was presented to be smaller (152 nm) than CTPP-ME, and CH-ME and CHA-ME presented lower EE (79% and 54%, respectively) than CTPP-ME. FT-IR revealed a stronger interaction of ME with CTPP-ME than with CH-ME. Both organisations pointed a significantly lower release than free ME, and the T50 value of CTPP-ME 3% (328 min) was higher than CH-ME (197 min). Both protected the ORAC activity of ME.

Methionine  of particle size and composition on local magnetic hyperthermia of chitosan-Mg1-xCoxFe2O4 nanohybrid.In this study, Mg(1-x)Co(x)Fe(2)O(4) (0≤x ≤ 1 with ∆x = 0) or MCFO nanoparticles were synthesised practicing a chemical co-precipitation method and tempered at 200, 400, 600, and 800°C respectively to investigate the structural places of the materials by X-ray diffractometer (XRD), transmission electron microscopy (TEM), and Fourier-transform infrared spectroscopy (FTIR). commanded annealing increased particle size for each value of x. The aim was to investigate how specific loss power (SLP) and maximum temperature (T(max)) during local magnetic hyperthermia were dissembled by structural changes consociated with particle size and composition. The lattice parameter, X-ray density, ionic radius, hopping length, bond length, cation-cation distance, and cation-anion distance increase with an increase in Co(2+) content. Raman and FTIR spectroscopy reveal changes in cation distribution with Co(2+) content and particle size.
