This study developed water-dispersible γ-oryzanol (WD-OZ) using microemulsion system and assessed their absorption in rats. While γ-oryzanol itself is hardly soluble in water, WD-OZ exhibited high water dispersibility, and γ-oryzanol, along with its metabolites, was detected in rat plasma. These findings provide a solid basis for future application of the microemulsion-based approach to enhance the bioavailability of γ-oryzanol in food.

Disruption of cholinesterases and, as a consequence, increased levels of acetylcholine lead to serious disturbances in the functioning of the nervous system, including death. The need for rapid administration of an antidote to restore esterase activity is critical, but practical implementation of this is often difficult. One promising solution may be the development of antidote delivery systems that will release the drug only when acetylcholine levels are elevated.

Gastrointestinal (GI) cancer represent significant health challenges, affecting the digestive system with often subtle symptoms that can delay diagnosis. GI cancers account for a higher global mortality rate than any other cancer, largely due to the limited availability of highly effective treatment options." Due to next-generation sequencing and new preclinical model tools, that we have learned more regarding its pathophysiology and molecular changes.

The aim of this study was to compare the functional properties of linseed oil powders made of three types of wall material (OSA starch + maltodextrin, OSA starch + nutriose, and OSA starch + inulin) and two types of emulsion phases (micro- and nanoemulsion). For these independent variables, the properties of the prepared emulsions (flow curves and viscosity) and the resulting powders (encapsulation efficiency, particle size distribution, water activity, bulk and tapped density, Carr's index, color parameters, and thermal stability) were determined. The results showed that emulsion viscosity and most powder properties were affected by the emulsion type.
