Abstract

Purpose: Exercise has a positive regulatory effect on gut microbiota and is also involved in regulating multiple physiological functions of the human body. This article tested the effects of basketball exercises at different exercise intensities on the gut microbiota of college students. Methods: Athlete research subjects (male, aged 18 - 25) were selected from the basketball team and trained at different intensities to obtain a total of 101 fresh fecal samples. DNA was extracted by a DNA extraction kit and bacterial 16S rRNA gene V3-V4 region high-throughput sequencing using the Illumina Hiseq platform. The downstream data were spliced, filtered and de-trimerized and then used to study the difference in gut microbiota. Results: Key bacterial taxa in the gut that responded to exercise intensity differed among athletes of different exercise intensities but most belonged to Firmicutes. With increasing exercise intensity, Butyricicoccus, Anaerostipes, Oxalobacter and Clostridium_IV in basketball players enrich. Further analysis of the functional prediction revealed that carbohydrate metabolism, amino acid metabolism, metabolism of xenobiotics and glycans and metabolism were significantly expressed in the gut microbiota of basketball athletes with high intensity. Conclusion: The study demonstrated that after long-term professional training, the gut microbiota of athletes adapts to exercise stimulators and can quickly respond to changes in exercise intensity. In high-intensity training, the organism is protected from harm by enriching some beneficial bacteria.

18. Four Ln-coordination polymers: synthesis, crystal structure, fluorescent sensing of nitrobenzene and Tb3+, and catalytic properties

Author

Tang, Yu-Yuan, Chen, Shuang, Wang, Cui-Juan, Zhu, Zi-Xin, and Liu, Dong-Ning

Abstract

In many sensing and catalytic applications, the target molecule is required to be carried in an effective manner in a specific condition. Metal-organic frameworks (MOFs) have high porosity, large surface area, and tunable functionality and are promising carriers for such purposes. Current approaches to detect Tb3+ and reduce 4-nitrophenol (4-NP) are based on multistep methods. We synthesized a series of coordination polymers (1–4) with excellent fluorescence and catalytic activity. Moreover, 1 and 2 exhibit significantly higher fluorescence than other compounds, indicating that 1 and 2 could be efficient multifunctional fluorescence probes for high-sensitivity sensing of nitrobenzene, and 1 can be used as a highly sensitive fluorescent sensor to detect Tb3+, with a detection limitation of 5 × 10−7 M. In addition, the as-prepared Ag@compound 1 shows remarkable catalytic performance to reduce 4-NP, with a reduction rate constant k as large as 2.07 × 10−2 s−1.

19. A terbium(III) organic framework as a fluorescent probe for selectively sensing of organic small molecules and metal ions especially nitrobenzene and Fe3+

Abstract

A terbium organic framework (Tb-MOF), {[Tb2(Pyznpy)6·4H2O]·2H2O}n (1) (Hpyznpy = 4-((3-(pyrazin-2-yl)-1H-pyrazol-1-yl) methyl) benzoic acid), has been synthesized under solvothermal conditions. X-ray crystal analysis indicates that 1 crystallizes in the triclinic form with P-1 space group, and six petal-like 1D chains are connected by hydrogen bonds and π···π interactions to form the 3D structure of 1. Tb-MOF 1 exhibits an intense green fluorescence under UV light. The fluorescent nature of 1 suggests that Tb-MOF 1 could be an efficient multifunctional fluorescence probe for sensitivity sensing of small organic molecules and metal ions, especially for nitrobenzene and Fe3+. The mechanism of the sensing properties was studied as well.
