Curculin elicited a sweet taste. After the sweetness of curculin diminished, application of deionized water or an acid to the tongue induced a sweet taste. The maximum sweetness of curculin itself was equivalent to the sweetness of 0.35 M sucrose. The maximum sweetness induced by 0.02 M citric acid or deionized water after curculin dissolved in a buffer of pH 6.0 was held in mouth for 3 min was also equivalent to that of 0.35 M sucrose. The sweetness induced by deionized water was completely suppressed by the presence of 1 mM CaCl2 or MgCl2, while that induced by an acid was not suppressed by the presence of divalent cations. Based on these results, the mechanism of the taste-modifying activity was discussed. Stability of curculin was examined under various conditions. The taste-modifying activity of curculin was unchanged when curculin was incubated at 50 degrees C for 1 h between pH 3 and 11.

Aims: This study aimed to evaluate the enamel remineralization effect of fluoride-incorporated bioactive glass (F-BG) toothpaste on artificial subsurface caries in primary teeth.
Materials And Methods: Forty sound primary maxillary incisors were subjected to a demineralizing solution for four days to induce artificial enamel caries. The teeth were randomly divided into four experimental groups ( = 10 per group): Group I, F-BG toothpaste (530 ppm fluoride) (BiominF); Group II, 0.

Hydrogen peroxide (HO) production through photocatalytic O reduction reaction (ORR) is a mild and cost-efficient alternative to the anthraquinone oxidation strategy. Of note, singlet state oxygen (O) plays a crucial role in ORR. Herein, a hollow TiO@TpPa (TOTP) S-scheme heterojunction by the Schiff base reactions involving 1,3,5-triformylphloroglucinol (Tp) and paraphenylenediamine (Pa) for efficient photocatalytic HO production in deionized water has been developed.

In recent years, liquid-solid triboelectric nanogenerators (L-S TENGs) have been rapidly developed in the field of liquid energy harvesting and self-powered sensing. This is due to a number of advantages inherent in the technology, including the low cost of fabricated materials, structural diversity, high charge-energy conversion efficiency, environmental friendliness, and a wide range of applications. As liquid phase dielectric materials typically used in L-S TENG, a variety of organic and inorganic single-phase liquids, including distilled water, acidic solutions, sodium chloride solutions, acetone, dimethyl sulfoxide, and acetonitrile, as well as paraffinic oils, have been used in experiments.
