Abstract Many functional food ingredients activate human bitter taste receptors (hTAS2Rs). In this study, A novel inhibitor, Trp-Trp, for hTAS2R14 was identified by searching for the agonist peptide's analogs. Trp-Trp also inhibited hTAS2R16, hTAS2R43, and hTAS2R46, which share the same agonists with hTAS2R14. The multi-functional characteristic of Trp-Trp is advantageous for use as bitterness-masking agents in functional foods.

Abstract The main objective of the work was to clarify the question - how will cell cultures functional state change after microgravity simulation when the shift in full strength direction takes place? Proliferation processes and apoptosis intensity in cell lines of rat glioma and human fibroblasts were compared in changing the position of flasks with cell culture in relation to the horizon. The detection of apoptosis and necrosis processes was carried out using flow cytofluorimetry. It was found that the change in full strength direction provides an inhibitory effect on tumor glial cells and fibroblasts’ proliferative activity enhances along with inhibition of apoptotic processes. Intensification of apoptotic processes in glioma cells and attenuation of cell death processes in normal cells - fibroblasts - are the result of cell cooperation disturbance.

The distribution equilibrium of gallium(III) between n-octylaniline dissolved in toluene and acidic aqueous succinate media has been investigated as a function of the concentration of extractant in the organic phase and concentration of hydrogen ions and gallium( III) ions in the aqueous phase. The stoichiometry of the extracted species was determined on the basis of slope analysis.Gallium(III) is extracted by the anion exchange mechanism as [RNH3+Ga(succinate)2]org. The temperature dependence of the extraction equilibria was examined by the temperature variation method. The extraction process is favoured with increasing temperature. It was found that a large number of cations and anions have a high tolerance limit. The selectivity of the extraction is increased by the use of suitable masking agents. The method affords the binary separation of gallium(III) from associated elements and was further extended to the analysis of a synthetic mixture.

Nanofibers have emerged as advanced fibers with broad use and potential in biomedical fields in recent decades. The process of healing is an innate immune response towards a pathophysiology such as wound. Ordinary time taken for wound healing is approximately 2–3 days depending upon the chronic state. Air moisture and microbes risk pathological manifestations leading to delayed or incomplete palliate process. An external agent that can provide balanced moisture, increasing cell proliferation with microbial infiltration or anti- bacterial activity, aids to speed the healing process. Apart from these qualities, an ideal material should be simple, cost effective, and repeatable. Nanofibers produced through electrospinning have become a promising strategy in the treatment of wounds. Apart from being simple in application, they are produced from natural or synthetic polymers. Nanofibers exhibit high surface area, nanoporosity, with a potential to load potent drugs or enzymes. Other biomedical applications include use of nanofibers as tissue scaffolds and as masking agents in modern cosmetics. Therefore nanofibers are excellent candidates for wound treatment and management. The current review is an attempt to discuss and present literature about different techniques, chemical materials, and entities used to produce efficient electrospun nanofibers for use in pathological, medicinal, or treatment or management of injury or laceration.
