Summary: Ionic hydrogels are suitable for drug delivery applications, and in this study, pH-sensitive P(AAc-co-AAm) hydrogels were investigated for swelling properties using a hydrophilic fluorescence probe, 4sPy. The fluorescence intensity of 4sPy was monitored during swelling processes at different pH values, showing similar behavior to trapped drug carriers. These hydrogels could be useful for targeted drug delivery systems in the jejunum, with potential for 4sPy as a monitoring probe for drug carriers.

Summary: Novel composite hydrogels based on poly(acrylic acid-co-acrylamide)/polyacrylamide pseudo-interpenetrating polymer networks (pIPNs) and magnetite were prepared through in situ precipitation of Fe3+/Fe2+ ions within the hydrogel structure. The size of the magnetite crystallites depended on the hydrogel composition, and an interaction between the hydrogel matrix and Fe ions influenced the formation of magnetite particles. The composite hydrogels exhibited pH and ionic strength responsiveness as well as superparamagnetic properties, demonstrating the potential of pIPNs as matrices for controlled inorganic particle deposition in polymer nanocomposite production.

Summary: The aim of this study was to investigate p(NIPAM) hydrogels cross-linked with ethylene glycol dimethacrylate as carriers for sulfanilamide. The structural characterization before and after sulfanilamide incorporation was done using FTIR, XRD and SEM. The swelling behavior of p(NIPAM) hydrogels of various cross-linking degrees was monitored with respect to temperature and pH, and the release of sulfanilamide was examined. The results showed that p(NIPAM) hydrogels are promising carriers for sulfanilamide due to their thermosensitivity, volume phase transition temperature close to physiological temperature, and satisfactory results for sulfanilamide incorporation and release.

Summary: This study investigated the water adsorption isotherms and thermal characteristics of pumpkin powder with various inulin additions to develop state diagrams. The results showed that the glass transition temperature and characteristic glass transition temperature of maximum-freeze-concentration increased with increasing inulin additions. The Peleg model was the most suitable for describing the sorption data of the pumpkin-inulin powders, and the Guggenheim-Anderson-de Boer (GAB) monolayer capacity decreased with increasing inulin concentration.

Summary: The study evaluated the rheology of dough and bread characteristics when 5% or 10% of wheat flour was replaced with lyophilized kale. The incorporation of lyophilized kale affected the rheological properties of the dough and resulted in a decrease in bread volume and porosity. The bread enriched with lyophilized kale also exhibited changes in color and texture, leading to a lower acceptability.
