        An important link between the gut microbiota and the circadian rhythm: imply for treatments of circadian rhythm sleep disorder

        Yufei Tian,Wei Yang,Gang Chen,Chuanlong Men,Yifan Gu,Ruilin Zhang,Laiyou Wang,Xin Zhang 한국식품과학회 2022 Food Science and Biotechnology Vol.31 No.2

        Currently, gut microbiota living in the gastrointestinaltract, plays an important role in regulatinghost’s sleep and circadian rhythms. As a tool, gut microbiotahas great potential for treating circadian disturbanceand circadian insomnia. However, the relationship betweengut microbiota and circadian rhythms is still unclear, andthe mechanism of action has still been the focus ofmicrobiome research. Therefore, this article summarizesthe current evidences associating gut microbiota with factorsthat impact host circadian rhythms neurology sleepdisorder. Moreover, we discuss the changes to these systemsin sleep disorder and the potential mechanism ofintestinal microbiota in regulating circadian rhythms neurologysleep disorder via microbial metabolites. Meanwhile,based on the role of intestinal flora, it is provided anovel insight into circadian related insomnia and will bebenefit the dietary treatment of circadian disturbance andthe circadian related insomnia.

        SF6 abatement in a packed bed plasma reactor: Role of zirconia size and optimization using RSM

        Yuan Tian,Xiaoxing Zhang,Yufei Wang,Zhaolun Cui,Ju Tang 한국공업화학회 2021 Journal of Industrial and Engineering Chemistry Vol.94 No.-

        This work describes plasma destruction of SF6 in a zirconia (ZrO2) packed bed plasma reactor (PBR). Electric signals, equivalent parameters, emission spectra and degradation results have been utilized toevaluate the influence of ZrO2 size on PBR discharge characteristics and SF6 degradation. The resultspresent that the size of ZrO2 has a significant impact on PBR discharge characteristics due to its influenceon physical parameters. Moreover, bigger ZrO2 beads packing shows a better performance in SF6degradation because of longer gas residence time. In addition, the key operating parameters includingflowrate, SF6 concentration, oxygen concentration, and water vapor concentration were optimized byresponse surface methodology (RSM) with Box-Behnken design (BBD). The proposed optimization modelshows satisfactory correlation between the predicted and actual results. For energy yield (EY), the mutualeffect offlowrate, SF6 concentration and water vapor concentration was significant. For SO2F2 selectivity,the mutual effect of SF6 concentration and water vapor concentration was significant. The optimum SF6abatement was predicted from RSM as 14.64 g/kWh and 14.42% for EY and SO2F2 selectivity atflowrate of200 mL/min, SF6 concentration of 3%, oxygen concentration of 0.83% and water vapor concentration of1.89%.

        A method to characterize ink performance by line resistance measurement through modeling for direct pen writing

        Dong Maolin,Tian Yufei,Wang Xin,Qian Jun 한국탄소학회 2023 Carbon Letters Vol.33 No.3

        The rational evaluation of carbon-based conductive ink performance is critical to both industrial production and applications. Herein, a model to evaluate writing performance of conductive ink by line resistance was proposed by investigating possible relations among different parameters and establishing relevant model to estimate ink writing performance. Bulk conductive inks were prepared and characterized to provide samples for model. To improve the precision of model, the impact of external factors including writing speed and angle was studied. Nonlinear regression and back propagation artificial neural network were employed to estimate line resistance, and cross check validation was conducted to prove robustness and precision of model. Most importantly, the investigation will open up a new path for the exploration of other carbon-based handwritten electronic devices.

        Preliminary study of genome-wide association identified novel susceptibility genes for thyroid-related hormones in Chinese population

        Huang Liang,Bai Fenghua,Zhang Yutian,Zhang Shanshan,Jin Tianbo,Wei Xingwei,Zhou Xiaoli,Lin Mei,Xie Yufei,He Chanyi,Lin Qi,Xie Tian,Ding Yipeng 한국유전학회 2022 Genes & Genomics Vol.44 No.8

        Background: Thyroid hormones are critical regulators of metabolism, development and growth in mammals. However, the genetic association of thyroid-related hormones in the Chinese Han population is not fully understood. Objective: We aimed to identify the genetic loci associated with circulating thyroid-related hormones concentrations in the healthy Chinese Han population. Methods: Genotyping was performed in 124 individuals using Applied Biosystems™ Axiom™ PMDA, and 796,288 single nucleotide polymorphisms (SNPs) were available for the GWAS analysis. For replication, eleven SNPs were selected as candidate loci for genotyping by Agena MassARRAY platform in additional samples (313 subjects). The values of p < 5 × 10- 6 suggest a suggestively significant genome-wide association with circulating thyroid-related hormones concentrations. Results: We identified that rs11178277 (PTPRB, p = 4.88 × 10- 07) and rs7320337 (LMO7DN-KCTD12, p = 1.22 × 10- 06) were associated with serum FT3 level. Three SNPs (rs4850041 in LOC105373394-LINC01249: p = 3.55 × 10- 06, rs6867291 in LINC02208: p = 2.40 × 10- 06 and rs79508321 in WWOX: p = 3.35 × 10- 06) were related to circulating T3 level. Rs12474167 (LOC105373394-LINC01249, p = 1.65 × 10- 06) and rs1864553 (IWS1, p = 2.00 × 10- 06) were associated with circulating T4 concentration. The association with TGA concentration was for rs17163542 in DISP1 (p = 3.46 × 10- 06) and rs12601151 in NOG-C17orf67 (p = 2.72 × 10- 07). Two genome-level significant SNPs (rs2114707 in LINC01314, p = 1.69 × 10- 06 and rs12601151, p = 1.41 × 10- 07) associated with serum TMA concentration were identified. Moreover, rs6083269 (CST1-CST2, p = 3.36 × 10- 06) was a significant locus for circulating TSH level. In replication, rs12601151 in NOG-C17orf67 was still associated with serum TGA level (p = 0.012). Conclusions: The GWAS reported 11 new suggestively significant loci associated with circulating thyroid-related hormones levels among the Chinese Han population. These findings represented suggestively biological candidates for circulating thyroid-related hormones levels and provided new insights into the mechanisms of regulating serum TGA concentration.
