The retention of bioactive compounds in the blend of wheat and rye flours and 4% roasted buckwheat hulls, dough before and after fermentation, and obtained bread were determined. In parallel, the content of Maillard reaction products (MRPs) and antioxidant capacity (AC) during technological steps of bread production were studied. The dough formation and fermentation process increased the content of phenolic acids and flavonoids and reduced the content of tocopherols, and no changes in glutathione as compared to the blend were noted. Moreover, the increased level of available lysine and AC were observed after dough fermentation. The baking process resulted in further increased phenolic acids, and flavonoids and decreased the tocopherols and glutathione contents. The bread was characterized by the highest values of parameters related to MRPs, such as the content of fluorescent intermediary compounds and final browning index compared to other analyzed steps.

Ionizing radiation-induced injury often occurs in nuclear accidents or large-dose radiotherapy, leading to acute radiation syndromes characterized by hematopoietic and gastrointestinal injuries even to death. However, current radioprotective drugs are only used in hospitals with unavoidable side effects. Here, we heated the aqueous solution of inulin, a polysaccharide dietary fiber, forming colon-retentive gel as a radiation protector in radiotherapy.

pH changes occur during bodily lesions, presenting an opportunity for leveraging pH-responsive delivery systems as signals for a targeted response. This review explores the design and application of pH-responsive delivery systems based on natural polysaccharides for the controlled release of bioactives. The article examines the development of diverse delivery carriers, including nanoparticles, nanofibers, nanogels, core-shell carriers, hydrogels, emulsions as well as liposomes and their capacity to respond to pH variations, enabling the precise and targeted delivery of bioactives within the human body.

Enzyme-based portable amperometric biosensors are precise and low-cost medical devices used for rapid cancer biomarker screening. Sarcosine (Sar) is an ideal biomarker for prostate cancer (PCa). Because human serum and urine contain complex interfering substances that can directly oxidize at the electrode surface, rapid Sar screening biosensors are relatively challenging and have rarely been reported.

Cholesterol (Cho) is commonly used to stabilize nanoliposomes; however, there is controversy on the relationship between Cho and health. In this study, we developed a novel multifunctional nanoliposome utilizing structurally similar sitogluside (SG) and dioscin (Dio) instead of Cho to anchor the phospholipid bilayer and synergistically modulate the membrane properties of the nanoliposome (DPPC or DOPC). The storage and gastrointestinal tract stability experiment demonstrated that the changes of physical and chemical properties, including the significantly reduced size and Dio retention rate of nanoliposomes synergistically modulated by SG and Dio compared to those of SG alone, regulated nanoliposomes.

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) represent a novel class of bioactive lipids with significant physiological roles. However, their identification, particularly of low-abundance FAHFA regioisomers, remains challenging due to their high structural similarity, low natural abundance, and the limited availability of reliable FAHFA standards. In this study, we present a QSAR-based FAHFA annotation strategy that integrates a QSAR model with an ester bond position (EP) rule to determine the EPs of FAHFA regioisomers.
