The objective was to investigate the influence of synergism between xanthan gum (X) and galactomannans (guar gum (G) and locust bean gum (L)) on the stickiness of the film formed after the application of polysaccharides on a surface. The adhesion of the film was evaluated using a texture analyzer. X, G, and L were examined in concentrated solutions (0.5, 1 and 1.5 %, w/w) and as a function of the gums mixing ratios (0/100, 20/80, 40/60, 50/50, 60/40, 80/20 and 100/0). The film stickiness increased significantly with gum concentration with G exhibiting less sticky films than with X and L. The binary mixture of X/G and X/L confirmed a synergistic interaction, increasing the firmness of mixtures and decreasing the film stickiness. Such findings open interesting applications for skincare product development using natural texturing agents with enhanced consistency with the residual film on the skin being pleasant and not sticky.

The growing body of experimental and computational studies suggested that the cross-neutralization antibody activity against Omicron variants may be driven by balance and tradeoff of multiple energetic factors and interaction contributions of the evolving escape hotspots involved in antigenic drift and convergent evolution. However, the dynamic and energetic details quantifying the balance and contribution of these factors, particularly the balancing nature of specific interactions formed by antibodies with the epitope residues remain scarcely characterized. In this study, we performed molecular dynamics simulations, ensemble-based deep mutational scanning of SARS-CoV-2 spike residues and binding free energy computations for two distinct groups of broadly neutralizing antibodies : E1 group (BD55-3152, BD55-3546 and BD5-5840) and F3 group (BD55-3372, BD55-4637 and BD55-5514).

Recent evidence indicates that PZA acts through disruption of coenzyme A synthesis under conditions that promote cellular stress. In contrast to its bactericidal action , PZA shows weak bacteriostatic activity against in axenic culture.

Metal-organic frameworks (MOFs) combined with polymers as hybrid materials offer numerous advantages such as enhanced performances through synergistic effects at their interface. The primary challenge in developing polymer/MOF hybrid matrix films is ensuring optimal dispersion and strong adhesion of crystalline MOFs to the polymer without aggregation, weak interaction, or phase separation. In this study, hierarchically porous UiO-66_NH/chitosan (ZrCSx-) films were designed by crystallizing UiO-66_NH within a chitosan (CS) skeleton.

Traditional colitis treatment strategies have issues such as side effects and poor lesion targeting. In this study, a milled black rice particle-stabilized Pickering emulsion (BR-5-DMN) has been developed as a delivery vehicle for 5-demethylnobiletin (5-DMN) to treat colitis. The alleviating effects of three 5-DMN delivery systems: BR-5-DMN, Tween 80 emulsion for upper gastrointestinal delivery, and soybean oil with most 5-DMN entering the colon were compared.

This study explores the synergistic effects of linoleic acid (LA) oxidation on the aggregation behavior and structural properties of wheat gluten (WG). Using lipoxygenase to induce LA oxidation, it was observed that this process significantly influenced WG's viscoelasticity and structural characteristics. Specifically, LA oxidation enhanced WG's viscoelastic properties while reducing its instantaneous elastic and recovery deformations.
