Influence of the addition of gum arabic and xanthan gum in the preparation of sodium alginate microcapsules coated with chitosan hydrochloride on the survival of Lacticaseibacillus rhamnosus GG.

The microencapsulation of Lactocaseibacillus rhamnosus GG in a matrix of sodium alginate, xanthan gum, gum arabic and chitosan hydrochloride is a promising strategy for protecting this probiotic during passage through the gastrointestinal tract. This study evaluated the influence on the viability of Lactocaseibacillus rhamnosus GG encapsulated with these polymers by external ionic gelation with vibratory extrusion and the microcapsules that showed the best results of capsulation efficiency, viability, size and morphology were analyzed by Fourier transform infrared spectroscopy (FTIR), thermal analysis (TGA) and exposure to environmental stress conditions and gastrointestinal simulation. The result revealed encapsulation efficiency values above 95 % for all formulations and survival rate higher than 6 log CFU/mL for most analyzed groups.

Comparison of principal component analysis algorithms for imputation in agrometeorological data in high dimension and reduced sample size.

Meteorological data acquired with precision, quality, and reliability are crucial in various agronomy fields, especially in studies related to reference evapotranspiration (ETo). ETo plays a fundamental role in the hydrological cycle, irrigation system planning and management, water demand modeling, water stress monitoring, water balance estimation, as well as in hydrological and environmental studies. However, temporal records often encounter issues such as missing measurements.

Platelet-Neutrophil aggregate formation induces NLRP3 inflammasome activation in VITT.

Background: Although rare, vaccine-induced thrombotic thrombocytopenia (VITT) following adenoviral vector COVID-19 vaccination is a concerning and often severe adverse effect of vaccination. The generation of high anti-platelet factor 4 (PF4) antibody titers, promotes the formation of immune complexes capable of activating platelets and neutrophils through FcγRIIa.

Objective: Given that Platelet-leukocyte aggregate (PLA) formation and inflammasome activation are common features of thromboinflammatory diseases, we aimed to evaluate if these are also features of VITT.

Hydrogen-designed spin-states of 2D silicon carbide and graphene nanostructures.

Identifying and manipulating spin in two-dimensional materials is of great interest in advancing quantum information and sensing technologies, as well as in the development of spintronic devices. Here, we investigate the influence of hydrogen adsorption on the electronic and magnetic properties of graphene-like triangulenes. We have constructed triangulenes from SiC monolayers, which have been successfully synthesized very recently, extending our investigation to include graphene triangulenes.
