Abstract:
This laboratory has compared several techniques in our effort to produce artifact-free SEM images in order to compare the effect of different stabilizers on microstructure of soft serve frozen yogurt and stirred yogurt. Such samples are a porous matrix of casein micelles fused to form chains which immobilize the liquid phase. Two sample preparation protocols were used: cryo-SEM for the product sampled at lower temperature, and encapsulation of those semi-liquid or soft-set yogurts within an agar gel tube or in drilled aluminum stubs / molds coated with low melting point 3% agar.

Abstract:
The investigation of properties of amphiphilic block copolymers as stabilizers for non-lamellar lyotropic liquid crystalline nanoparticles represents a fundamental issue for the formation, stability and upgraded functionality of these nanosystems. The aim of this work is to use amphiphilic block copolymers, not studied before, as stabilizers of glyceryl monooleate 1-(cis-9-octadecenoyl)-rac-glycerol (GMO) colloidal dispersions. Nanosystems were prepared with the use of poly(ethylene oxide)-b-poly(lactic acid) (PEO-b-PLA) and poly(ethylene oxide)-b-poly(5-methyl-5-ethyloxycarbonyl-1,3-dioxan-2-

Abstract:
In this study, Pickering emulsion gels were prepared by the self-gel method based on kappa carrageenan (kC). The effects of particle stabilizers and polysaccharide concentrations on the microstructure, rheological characteristics, and texture of Pickering emulsion gels stabilized by xanthan gum/lysozyme nanoparticles (XG/Ly NPs) with kC were discussed. The viscoelasticity of Pickering emulsion gels increased significantly with the increase of kC and XG/Ly NPs. The results of temperature sweep showed that the gel formation mainly depended on the kC addition. The XG/Ly NPs addition could acceler

Abstract:
The modern brewing industry generates high amounts of solid wastes containing biopolymers—proteins and polysaccharides—with interesting technological and functional properties. The novelty of this study was to use raw by-product from the brewing industry in the development of high internal phase emulsion (HIPE) gels. Thus, the influence of the emulsion’s aqueous phase pH and the by-product’s concentration on structural and physical stability of the emulsions was studied. The microstructure was analyzed using cryo-field emission scanning electron microscopy. To evaluate the rheological behavior

Abstract Background Obefazimod is an oral, once-daily, small molecule in phase 3 clinical trials for the treatment of patients with ulcerative colitis (UC). Obefazimod selectively enhances the expression of a single micro-RNA (miRNA), miR-124. miRNAs function by binding to specific mRNA targets and reducing their translation into their respective proteins. Enhanced expression of miR-124 results in a decrease in cytokines and immune cells, helping to reduce inflammation and potentially controlling the progression of chronic conditions like UC.

Abstract Biovariability poses a significant challenge in the oral administration of sotorasib (AMG 510), an FDA-approved KRAS G12C inhibitor for non-small cell lung cancer (NSCLC). Sotorasib, a weakly basic drug with limited aqueous and pH-dependent solubility, necessitates a high daily dose (960 mg; 8 tablets). In general, high doses, pill burdens, and poor solubility often result in poor patient compliance and therapeutic outcomes. Co-administration with proton pump inhibitors (PPIs) in cancer patients significantly reduces the bioavailability of weakly basic drugs including sotorasib. To ad
