| 2 | Biomarkers of aging显示文摘Aging biomarkers are a combination of biological parameters to(i)assess age-related changes,(ii)track the physiological aging process,and(iii)predict the transition into a pathological status.Although a broad spectrum of aging biomarkers has been developed,their potential uses and limitations remain poorly characterized.An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research:How old are we?Why do we get old?And how can we age slower?This review aims to address this need.Here,we summarize our current knowledge of biomarkers developed for cellular,organ,and organismal levels of aging,comprising six pillars:physiological characteristics,medical imaging,histological features,cellular alterations,molecular changes,and secretory factors.To fulfill all these requisites,we propose that aging biomarkers should qualify for being specific,systemic,and clinically relevant. | Aging Biomarker Consortium Hainan Bao Jiani Cao Mengting Chen Min Chen Wei Chen Xiao Chen Yanhao Chen Yu Chen Yutian Chen Zhiyang Chen Jagadish K Chhetri Yingjie Ding Junlin Feng Jun Guo Mengmeng Guo Chuting He Yujuan Jia Haiping Jiang Ying Jing Dingfeng Li Jiaming Li Jingyi Li Qinhao Liang Rui Liang Feng Liu Xiaoqian Liu Zuojun Liu Oscar Junhong Luo Jianwei Lv Jingyi Ma Kehang Mao Jiawei Nie Xinhua Qiao Xinpei Sun Xiaoqiang Tang Jianfang Wang Qiaoran Wang Siyuan Wang Xuan Wang Yaning Wang Yuhan Wang Rimo Wu Kai Xia Fu-Hui Xiao Lingyan Xu Yingying Xu Haoteng Yan Liang Yang Ruici Yang Yuanxin Yang Yilin Ying Le Zhang Weiwei Zhang Wenwan Zhang Xing Zhang Zhuo Zhang Min Zhou Rui Zhou Qingchen Zhu Zhengmao Zhu Feng Cao Zhongwei Cao Piu Chan Chang Chen Guobing Chen Hou-Zao Chen Jun Chen Weimin Ci Bi-Sen Ding Qiurong Ding Feng Gao Jing-Dong JHan Kai Huang Zhenyu Ju Qing-Peng Kong Ji Li Jian Li Xin Li Baohua Liu Feng Liu Lin Liu Qiang Liu Qiang Liu Xingguo Liu Yong Liu Xianghang Luo Shuai Ma Xinran Ma Zhiyong Mao Jing Nie Yaojin Peng Jing Qu Jie Ren Ruibao Ren Moshi Song Zhou Songyang Yi Eve Sun Yu Sun Mei Tian Shusen Wang Si Wang Xia Wang Xiaoning Wang Yan-Jiang Wang Yunfang Wang Catherine CL Wong Andy Peng Xiang Yichuan Xiao Zhengwei Xie Daichao Xu Jing Ye Rui Yue Cuntai Zhang Hongbo Zhang Liang Zhang Weiqi Zhang Yong Zhang Yun-Wu Zhang Zhuohua Zhang Tongbiao Zhao Yuzheng Zhao Dahai Zhu Weiguo Zou Gang Pei Guang-Hui Liu | 2023 | Science China(Life Sciences)2023，66，5： | 2 |
| 3 | Explicating the Role of Metal Centers in Porphyrin-Based MOFs of PCN-222(M) for Electrochemical Reduction of CO_(2)显示文摘The porphyrin-based MOFs formed by combining Zrclusters and porphyrin carboxylic acids with clear M-Nactive centers show unique advantages in electrocatalytic reduction of CO(CORR). However, its conductivity is still the bottleneck that limits its catalytic activity due to the electrical insulation of the Zr cluster. Therefore, the porphyrin-based MOFs of PCN-222(M)(M = Mn, Co, Ni, Zn) with explicit M-Ncoordination were combined with the highly conductive material carbon nanotube(CNT) for discussing the influence of metal centers on the CORR performance based on theoretical calculations and experimental observations. The results show that the PCN-222(Mn)/CNT, PCN-222(Co)/CNT, and PCN-222(Zn)/CNT all exhibit high selectivity to CO(FECO > 80%) in the range of-0.60 to-0.70 V vs. RHE. The FECOmax of PCN-222(Mn)/CNT(-0.60 V vs. RHE), PCN-222(Co)/CNT(-0.65 V vs. RHE), and PCN-222(Zn)/CNT(-0.70 V vs.RHE) are 88.5%, 89.3% and 92.5%, respectively. The high catalytic activity of PCN-222(Mn)/CNT and PCN-222(Co)/CNT comes from the excellent electron mobility of their porphyrin rings and their low ΔG*COOH(0.87 and 0.58 eV). It reveals that the strength of backbonding π of the transition metal and its influence on the electron mobility in the porphyrin ring can affect its CORR activity. | Mengjie Liu Mengting Peng Baoxia Dong Yunlei Teng Ligang Feng Qiang Xu | 2022 | Chinese Journal of Structural Chemistry2022，41，7： | 1 |
| 4 | Tetrahedral framework nucleic acid carrying angiogenic peptide prevents bisphosphonate-related osteonecrosis of the jaw by promoting angiogenesis显示文摘The significant clinical feature of bisphosphonate-related osteonecrosis of the jaw(BRONJ)is the exposure of the necrotic jaw.Other clinical manifestations include jaw pain,swelling,abscess,and skin fistula,which seriously affect the patients’life,and there is no radical cure.Thus,new methods need to be found to prevent the occurrence of BRONJ.Here,a novel nanoparticle,t FNA-KLT,was successfully synthesized by us,in which the nanoparticle tetrahedral framework nucleic acid(tFNA)was used for carrying angiogenic peptide,KLT,and then further enhanced angiogenesis.TFNA-KLT possessed the same characteristics as tFNA,such as simple synthesis,stable structure,and good biocompatibility.Meanwhile,tFNA enhanced the stability of KLT and carried more KLT to interact with endothelial cells.First,it was confirmed that tFNA-KLT had the superior angiogenic ability to tFNA and KLT both in vitro and in vivo.Then we apply tFNA-KLT to the prevention of BRONJ.The results showed that tFNA-KLT can effectively prevent the occurrence of BRONJ by accelerating angiogenesis.In summary,the prepared novel nanoparticle,tFNA-KLT,was firstly synthesized by us.It was also firstly confirmed by us that tFNA-KLT significantly enhanced angiogenesis and can effectively prevent the occurrence of BRONJ by accelerating angiogenesis,thus providing a new avenue for the prevention of BRONJ and a new choice for therapeutic angiogenesis. | Dan Zhao Dexuan Xiao Mengting Liu Jiajie Li Shuanglin Peng Qing He Yue Sun Jingang Xiao Yunfeng Lin | 2022 | International Journal of Oral Science2022，14，2： | 0 |

| 7 | Controllable Generation of Reactive Oxygen Species on Cyano-Group-Modified Carbon Nitride for Selective Epoxidation of Styrene显示文摘The controlled generation of reactive oxygen species(ROS)to selectively epoxidize styrene is a grand challenge.Herein,cyano-group-modified carbon nitrides(CNCY_(x) and CN-T_(y))are prepared,and the catalysts show better performance in regulating ROS and producing styrene oxide than the cyano-free sample.The in situ diffuse reflectance infrared and density functional theory calculation results reveal that the cyano group acts as the adsorption and activation site of oxygen.X-ray photoelectron spectroscopy and NMR spectrum results confirm that the cyano group bonds with the intact heptazine ring.This unique structure could inhibit H_(2)O_(2) and,OH formation,resulting in high selectivity of styrene oxide.Furthermore,high catalytic activity is still achieved when the system scales up to 2.7 L with 100 g styrene under solar light irradiation.The strategy of cyano group modification gives a new insight into regulating spatial configuration for tuning the utilization of oxygen-active species and shows potential applications in industry. | Hao Tan Peng Kong Riguang Zhang Mengting Gao Meixian Liu Xianmo Gu Weifeng Liu Zhanfeng Zheng | 2021 | The Innovation2021，2，1： | 0 |
| 8 | CuBr-promoted domino Biginelli reaction for the diastereoselective synthesis of bridged polyheterocycles:Mechanism studies and in vitro anti-tumor activities显示文摘The low-cost CuBr-promoted domino Biginelli reaction among readily available ketones,salicylaldehyde derivatives and 3-amino-1,2,4-triazole was studied under solvothermal conditions,giving the novel bridged polyheterocycles bearing two or three stereocenters depending on the starting ketones.This multicomponent reaction proceeded with high diastereoselectivity(dr>20:1)based on a combined~1 H NMR,crystallographic and supercritical fluid chromatographic(SFC)analysis of the product.Time-dependent high-resolution mass spectrometry(HRMS)was performed to track the reaction process,and several key intermediates were identified,leading to the drawing of a plausible reaction mechanism.Density functional theory(DFT)calculation was supplemented,and two reaction pathways were differentiated.Moreover,in vitro antitumor activity was evaluated using HeLa and HepG2 cell lines,and two of these polyheterocycles demonstrated promising activities against HepG2 cells with EC50 down to 10μmol/L.Additionally,ESI-MS/MS studies on all the polyheterocycles suggest a common fragmentation pathway(loss of one molecule of amino-triazole)they shared,providing the first-hand fragmentation rules for future rapid structural identification of them.The multicomponent domino reaction presented here may offer prospects for future design of more efficient strategies to access medicinally important bridged polyheterocycles. | Mengting Zeng Ying Xue Yunan Qin Fen Peng Quan Li Ming-Hua Zeng | 2022 | Chinese Chemical Letters2022，33，11： | 0 |
