Preparation of （2E）-3-（4＇-Halophenyl）prop-2-enoyl Sulfachlorpyridazine Sodium Salts and Their Interaction with Bovine Serum Albumin by Fluorescence Spectroscopy

引用

Chemical Research in Chinese Universities 2013年第5期29卷 854-860页

作者： DU Chuan-rong LUO Xuan WEI Jin-rui HE ting-ting ZHENG Xiao-yu lin Cui-wu School of Chemistry and Chemical Engineering Guangxi University Nanning 530004 P. R. China

Three （2E）-3-（4＇-halophenyl）prop-2-enoyl sulfachlorpyridazine sodium salts（XPSCA） were synthesized. Their chemical structures were confirmed by IH NMR and 13C NMR, electrospray ionization mass spectrometry （ESI-MS）, and infrared（IR） spectroscopy. The interactions between XPSCA and bovine serum albumin（BSA） were investigated under imitated physiological condition by fluorescence quenching technique and UV-Vis absorption spectroscopy according to the Stern-Volmer equation. The results from the emission quenching at different tempera- tures indicate that the quenching mechanism of serum albumin by XPSCA was static quenching mechanism at low XPSCA concentrations or a combined quenching（static and dynamic） mechanism at higher XPSCA concentrations. At different temperatures, the binding constant and the binding sites of XPSCA with BSA were investigated, and the distances were evaluated according to F6rster non-radiative resonance energy transfer theory. The thermodynamic parameters were calculated according to van＇t Hoff equation, which implies that both van der Waals interaction and hydrogen bond played major roles in stabilizing the XPSCA-BSA complexes, whereas hydrophobic interactions were secondary. Moreover, the conformational changes in BSA were analyzed by synchronous fluorescence spectra.

Information hiding schemes based on vector quantization （VQ） usually require lengthy VQ encoding and decoding processes. In this paper, we propose an efficient information hiding method based on closest paired tree structure vector quantization （CPTSVQ）. The simulation result shows that the execution time of the proposed scheme is much shorter than that attained by previous approaches.

Unripe Fruit Extracts of <i>Mangifera indica L.</i>Protect against AGEs Formation, Melanogenesis and UVA-Induced Cell Damage

引用

Food and Nutrition Sciences 2019年第2期10卷 188-197页

作者： Chin-Hsiu yu yu-ting lin Hsiang-ling Su Kai-Wen Kan Fu-Chen Liu Shan-yu lin yu-Ming Chung Hsin-Fen Hsu yung-Hsiang lin TCI Research and Design Center TCI Co. Ltd. Taiwan

In this study, we explored the effects of unripe fruit extracts of Mangifera indica L. on the anti-aging activity in skin cells. Mangifera indica L. is a popular economical and medicinal plant with numerous health-beneficial properties. The aqueous extracts of unripe fruit of Mangifera indica L. were obtained and subjected to HPLC and NMR analyses for the identification of bioactive compounds. The anti-glycation effect of Mango unripe fruit extracts was monitored by in vitro model system of AGEs (Advanced glycation end products) formation. Mango unripe fruit extracts significantly inhibited the AGEs formation in a dose-dependent manner. Meanwhile, Mango unripe fruit extracts possessed a comparable efficiency to commercialized Kojic acids in the inhibition of melanogenesis in B16-F10 melanoma cells. The UVA-induced cell damages can be prevented and repaired by Mango unripe fruit extracts in skin fibroblast CCD-966SK. Compared to the untreated control, Mango unripe fruit extracts significantly increased the cell viability while being applied before (36%) or after (43%) UVA irradiation. These results verified the potential application of Mango unripe fruit extracts in the skin protection and recovery from UVA irradiation, as well as the suppression of AGEs formation and melanogenesis.

MXene Hybridized Polymer with Enhanced Electromagnetic Energy Harvest for Sensitized Microwave Actuation and Self-Powered Motion Sensing

Polymeric microwave actuators combining tissue-like softness with programmable microwave-responsive deformation hold great promise for mobile intelligent devices and bionic soft robots. However, their application is challenged by restricted electromagnetic sensitivity and intricate sensing coupling. In this study, a sensitized polymeric microwave actuator is fabricated by hybridizing a liquid crystal polymer with Ti3C2Tx (MXene). Compared to the initial counterpart, the hybrid polymer exhibits unique space-charge polarization and interfacial polarization, resulting in significant improvements of 230% in the dielectric loss factor and 830% in the apparent efficiency of electromagnetic energy harvest. The sensitized microwave actuation demonstrates as the shortened response time of nearly 10 s, which is merely 13% of that for the initial shape memory polymer. Moreover, the ultra-low content of MXene (up to 0.15 wt%) benefits for maintaining the actuation potential of the hybrid polymer. An innovative self-powered sensing prototype that combines driving and piezoelectric polymers is developed, which generates real-time electric potential feedback (open-circuit potential of similar to 3 mV) during actuation. The polarization-dominant energy conversion mechanism observed in the MXene-polymer hybrid structure furnishes a new approach for developing efficient electromagnetic dissipative structures and shows potential for advancing polymeric electromagnetic intelligent devices.
