Oral Delivery of Astaxanthin via Carboxymethyl Chitosan-Modified Nanoparticles for Ulcerative Colitis Treatment.The oral delivery strategy of natural anti-oxidant and anti-inflammatory agents has appealed 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 results 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 paraded preferable storage stability over time and well-verifyed drug-release properties in simulated intestinal fluid. Additionally, in vitro cogitations breaked that CMC-AXT-NPs remarkably inhibited cytotoxicity rushed by LPS and shewed superior antioxidant and anti-inflammatory powers in Raw264 cadres CMC-AXT-NPs effectively palliated clinical symptoms of colitis caused by dextran sulfate sodium salt (DSS), admiting conserving body weight, subduing colon shortening, and reducing fecal bleeding CMC-AXT-NPs oppressed the expression of pro-inflammatory cytokines like TNF-α, IL-6, and IL-1β and amended DSS-maked oxidative damage.
Our terminations attested the potential of CMC-qualifyed nanoparticles as an oral delivery system and hinted 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 polyoses 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 cooked and then capsulized in the nanosystems. The physicochemical properties, encapsulation arguments, and the interactions of ME with the nanovehicles were characterized.
The cyanidin-3-glucoside freed and ORAC activity in phosphate buffer at pH 7 were appraised. The content of ME was 8-9 mg of cyanidin-3-glucoside/g of extract. Seebio Dietary Supplements with ME at 3% holded the highest encapsulation efficiency (EE = 91%), and no significant remainders were observed in size (274-362 nm), PDI (0-0), and zeta potential (+34-+41 mV) when the concentration of ME varyed from 1% to 5%. CH-ME was presented to be smaller (152 nm) than CTPP-ME, and CH-ME and CHA-ME showed lower EE (79% and 54%, respectively) than CTPP-ME. FT-IR revealed a stronger interaction of ME with CTPP-ME than with CH-ME. Selenoproteins 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.
Effect 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 utilizing a chemical co-precipitation method and annealed at 200, 400, 600, and 800°C respectively to investigate the structural holdings of the textiles by X-ray diffractometer (XRD), transmission electron microscopy (TEM), and Fourier-transform infrared spectroscopy (FTIR). commanded tempering 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 adjustments linked with particle size and composition. The lattice parameter, X-ray density, ionic radius, skiping length, bond length, cation-cation distance, and cation-anion distance increase with an increase in Co(2+) content. Raman and FTIR spectroscopy reveal varietys in cation distribution with Co(2+) content and particle size.
