2Arginine, N-carbamylglutamate,and glutamine exert protective effects against oxidative stress in rat intestine显示文摘The objective of the current study is to evaluate the effects of dietary supplementation with arginine(ARG), N-carbamylglutamate(NCG), and glutamine(GLN) on rat intestinal morphology and antioxidant status under oxidative stress. Rats were fed for 30 d with one of the following iso-nitrogenous diets:basal diet(BD), BD plus 1% ARG, BD plus 0.1% NCG, and BD plus 1% GLN. On day 28, half of the rats fed BD were intraperitoneally injected with 12 mg/kg body weight of diquat(DT; i.e., the DT group) and the other half was intraperitoneally injected with sterile solution(i,e., the control group). The other diet groups were intraperitoneally injected with 12 mg/kg body weight of DT(i,e., DT + 1% GLN [DT + GLN],DT + 1% ARG [DT + ARG], and DT + 0.1% NCG [DT + NCG]). Rat jejunum samples obtained at 48 h after DT injection were analyzed. Results showed that DT significantly decreased catalase(CAT) activity and glutathione(GSH) content by 58.25% and 56.57%, respectively, and elevated malondialdehyde(MDA)content and crypt depth(CD) by 19.39% and 22.13%, respectively, in the jejunum(P < 0.05, relative to the control group). Compared with the DT group, the DT + GLN group exhibited significantly improved villus height(VH), villus width(VW), villus surface area(VSA), CD and total antioxidant capacity(T-AOC) activity(P < 0.05); the DT + ARG group exhibited significantly increased the ratio of VH to CD(H:D) and TAOC activity(P < 0.05); the DT + GLN, DT + ARG and DT + NCG groups exhibited significantly enhanced CAT activity and GSH content as well as decreased MDA content(P < 0.05). Moreover, VH, VW, VSA, CD and GSH content in the DT + GLN group were higher whereas MDA content was lower compared with the corresponding values observed in both the DT + ARG and the DT + NCG groups(P < 0.05). The H:D ratio in the DT + ARG group significantly increased compared with that in the DT + NCG and DT + GLN groups(P < 0.05). Collectively, this study suggested that dietary supplementation with 1% GLN, 0.1% NCG,and 1% ARG was effective in enhancing the antioxidant status and maintaining the morphological structure of rat jejunum under oxidative stress; of these supplements, 1% GLN exerted the greatest effects on mitigating oxidative stress.Liang Xiao Wei Cao Guangmang Liu Tingting Fang Xianjian Wu Gang Jia Xiaoling Chen Hua Zhao Jing Wang Caimei Wu Jingyi Cai 2016Animal Nutrition2016,,3:12
3Endovascular treatment with or without intravenous alteplase for acute ischaemic stroke due to basilar artery occlusion显示文摘Background and purpose It remains controversial if endovascular treatment(EVT)can improve the outcome of patients with acute basilar artery occlusion(BAO).This study aims to compare the functional outcomes between EVT with and without intravenous thrombolysis(IVT)first in patients who had acute ischaemic stroke(AIS)due to BAO.Methods Patients who had AIS with BAO who underwent EVT within 24 hours of onset were enrolled in this multicentre cohort study,and the efficacy and safety were compared between IVT+EVT and direct EVT.The primary outcome was 90-day functional independence.All outcomes were assessed with adjusted OR(aOR)from the multivariable logistic regression.In addition,a meta-analysis was performed on all recently published pivotal studies on functional independence after EVT in patients with BAO.Results Of 310 enrolled patients with BAO,241(78%)were treated with direct EVT and 69(22%)with IVT+EVT.Direct EVT was associated with a worse functional outcome(aOR,0.46(95%CI 0.24 to 0.85),p=0.01).IVT+EVT was associated with a lower percentage of patients who needed≥3 passes of stent retriever(10.14%vs 20.75%).The meta-analysis regression revealed a potential positive correlation between bridging with IVT first and functional independence(r=0.14(95%CI 0.05 to 0.24),p<0.01).Conclusions This study showed that compared with direct EVT,EVT with IVT first was associated with better functional outcomes in patients with BAO treated within 24 hours of onset.The meta-analysis demonstrated similar favourable efficacy of IVT first followed by EVT in patients with BAO.Ximing Nie David Wang Yuehua Pu Yufei Wei Qixuan Lu Hongyi Yan Xin Liu Lina Zheng Jingyi Liu Xinxuan Yang Yarong Ding Dacheng Liu Wanying Duan Zhe Zhang Zhonghua Yang Miao Wen Weibin Gu Xinyi Hou Xinyi Leng Yuesong Pan Zhongrong Miao Liping Liu 2022Stroke & Vascular Neurology2022,7,3:10

7Successful Production of an All-Female Common Carp (Cyprinus carpio L.) Population Using cyp17a1-Deficient Neomale Carp显示文摘Due to sexual dimorphism in the growth of certain cultured fish species,the production of monosex fishes is desirable for the aquaculture industry.Nowadays,the most widely practiced technique available for the mass production of monosex fish populations is sex steroid-induced sex reversal.Here,a novel strategy for the successful production of all-female(AF)common carp(Cyprinus carpio L.),to take advantage of the sexual dimorphism in growth documented in this species,has been developed using genetic engineering via single gene-targeting manipulation without any exogenous hormone treatments.Male and female heterozygous cyp17a1-deficient common carp were first obtained using the clustered regularly interspaced short palindromic repeats/CRISPR-associated endonuclease 9(CRISPR/Cas9)technique.An all-male phenotype for homozygous cyp17a1-deficient carp,regardless of the individuals’sexdetermination genotypes(XY or XX),has been observed.A male-specific DNA marker newly identified in our laboratory was used to screen the neomale carp population with the XX genotype from the cyp17a1-deficient carp.These neomale carp develop a normal testis structure with normal spermatogenesis and sperm capacity.The neomale common carp were then mated with wild-type(WT)females(cyp17a1^(+/+)XX genotype)using artificial fertilization.All the AF offspring sample fish from the neomale-WT female mating were confirmed as having the cyp17a^(1+/-)XX genotype,and normal development of gonads to ovaries was observed in 100.00%of this group at eight months post-fertilization(mpf).A total of 1000 carp fingerlings,500 from the WT male and female and 500 from the neomale and WT female mating,were mixed and reared in the same pond.The average body weight of cyp17a1^(+/-)XX females was higher by 6.60%(8 mpf)and 32.66%(12 mpf)than that of the control common carp.Our study demonstrates the first successful production of a monosex teleost population with the advantages of sexual dimorphism in growth using genetic manipulation targeting a single locus.Gang Zhai Tingting Shu Kuangxin Chen Qiyong Lou Jingyi Jia Jianfei Huang Chuang Shi Xia Jin Jiangyan He Donghuo Jiang Xueqiao Qian Wei Hu Zhan Yin 2022Engineering2022,8,1:7

9An imine-linked covalent organic framework as the host material for sulfur loading in lithium–sulfur batteries显示文摘Lithium–sulfur(Li–S) batteries have high theoretical specific capacity, providing new opportunities for the next generation of secondary battery. Covalent organic framework(COF) as a new porous crystalline material has been used as the host material in Li–S battery to improve the cell's cycling stability. In this paper, an imine-linked TAPB-PDA-COF was applied as the host material for sulfur loading(60%) in Li–S battery. The TAPB-PDA-COF has a beehive-like morphology with high thermal stability(up to 500 ℃).In the electrochemical experiment, the performance of the composite cathode with acetylene black(AB) and super-P(S-P) as the conductive additives was studied individually. The initial discharge capacity under 0.2 A/g current density was 991 mAh/g and 1357 mAh/g for TAPB-PDA-COF/S@A-B and TAPB-PDACOF/S@S-P, respectively. The better result of S-P based cathode than A-B could be due to the better conductivity of the S-P, as proved by the EIS results. When further increased the current density to 2 A/g,the S-P based composite cathode can still deliver a comparable initial discharge capacity of 630 and 274 mAh/g capacity remained after 940 cycles. This results will inspire researchers develop more suitable conductive additives together with the host materials for high performance Li–S battery.Jianyi Wang Liping Si Qin Wei Xujia Hong Ligui Lin Xin Li Jingyi Chen Peibiao Wen Yuepeng Cai 2019Journal of Energy Chemistry2019,28,1:7

11The landscape of aging显示文摘Aging is characterized by a progressive deterioration of physiological integrity,leading to impaired functional ability and ultimately increased susceptibility to death.It is a major risk factor for chronic human diseases,including cardiovascular disease,diabetes,neurological degeneration,and cancer.Therefore,the growing emphasis on “healthy aging” raises a series of important questions in life and social sciences.In recent years,there has been unprecedented progress in aging research,particularly the discovery that the rate of aging is at least partly controlled by evolutionarily conserved genetic pathways and biological processes.In an attempt to bring full-fledged understanding to both the aging process and age-associated diseases,we review the descriptive,conceptual,and interventive aspects of the landscape of aging composed of a number of layers at the cellular,tissue,organ,organ system,and organismal levels.Yusheng Cai Wei Song Jiaming Li Ying Jing Chuqian Liang Liyuan Zhang Xia Zhang Wenhui Zhang Beibei Liu Yongpan An Jingyi Li Baixue Tang Siyu Pei Xueying Wu Yuxuan Liu Cheng-Le Zhuang Yilin Ying Xuefeng Dou Yu Chen Fu-Hui Xiao Dingfeng Li Ruici Yang Ya Zhao Yang Wang Lihui Wang Yujing Li Shuai Ma Si Wang Xiaoyuan Song Jie Ren Liang Zhang Jun Wang Weiqi Zhang Zhengwei Xie Jing Qu Jianwei Wang Yichuan Xiao Ye Tian Gelin Wang Ping Hu Jing Ye Yu Sun Zhiyong Mao Qing-Peng Kong Qiang Liu Weiguo Zou Xiao-Li Tian Zhi-Xiong Xiao Yong Liu Jun-Ping Liu Moshi Song Jing-Dong J.Han Guang-Hui Liu 2022Science China(Life Sciences)2022,65,12:4

13Calcium phosphate nanoparticles show an effective activation of the innate immune response in vitro and in vivo after functionalization with flagellin显示文摘For subunit vaccines,adjuvants play a key role in shaping the magnitude,persistence and form of targeted antigen-specific immune response.Flagellin is a potent immune activator by bridging innate inflammatory responses and adaptive immunity and an adjuvant candidate for clinical application.Calcium phosphate nanoparticles are efficient carriers for different biomolecules like DNA,RNA,peptides and proteins.Flagellin-functionalized calcium phosphate nanoparticles were prepared and their immunostimuiatory effect on the innate immune system,i.e.the cytokine production,was studied.They induced the production of the proinflammatory cytokines IL-8(Caco-2 cells) and IL-1β(bone marrow-derived macrophages;BMDM) in vitro and IL-6 in vivo after intraperitoneal injection in mice.The immunostimulation was more pronounced than with free flagellin.Diana Kozlova Viktoriya Sokolova Maohua Zhong Ejuan Zhang Jingyi Yang Wei Li Yi Yang Jan Buer Astrid Maria Westendorf Matthias Epple Huimin Yan 2014Virologica Sinica2014,29,1:3
14A review on perfluoroalkyl acids studies:Environmental behaviors,toxic effects,and ecological and health risks显示文摘Perfluoroalkyl acids(PFAAs)are emerging persistent organic pollutants that are globally distributed in the environment.In the present review,the occurrence of PFAAs and their behavior in aquatic ecosystem were summarized,and the health and ecological risk assessment and the multimedia fate simulation were investigated.PFAAs are most likely to exist in the aqueous phase,and PFAAs in atmosphere are also able to enter water bodies through diffusion and wet and dry deposition and eventually become widely distributed in various environmental media.The air-solid partition is considered to be one of the major factors in the long-distance transportation of the pollutants.The pKa values and organic carbon fraction of the sediment could influence the partition of PFAAs between water and sediment.Otherwise,PFAAs have teratogenic,mutagenic and other toxic effects and they could be accumulated by biota,and magnified through trophic level.The ecological and health risks of PFOA and PFOS were assessment.In order to explore the partition mechanism and reduce the uncertainty of the simulation of the transport,transformation and fate,the experimental methods on physicochemical properties of PFAAs should be developed.Moreover,further studies on toxicities of PFAAs are necessary for health and ecological risk assessment.Wenxiu Liu Jingyi Wu Wei He Fuliu Xu 2019Ecosystem Health and Sustainability2019,5,1:3
15A novel Z-scheme CeO_(2)/g-C_(3)N_(4)heterojunction photocatalyst for degradation of Bisphenol A and hydrogen evolution and insight of the photocatalysis mechanism显示文摘CeO_(2)/g-C_(3)N_(4)heterojunction photocatalyst had been successfully fabricated through a one-step in-situ pyrolysis formation of 3D hollow CeO_(2)mesoporous nanospheres and 2D g-C_(3)N_(4)nanosheets together with simultaneous removal of carbon sphere templates after heat treatment.The sample shows high catalytic performances for photocatalytic hydrogen generation and photocatalytic oxidation of Bisphenol A(BPA)under visible light irradiation,and the catalytic degradation route of BPA was suggested by the degradation products determined by GC-MS.The enhancing catalytic activity was attributed to the effective interfacial charge migration and separation.Finally,it was proposed that the CeO_(2)/g-C_(3)N_(4)heterojunction photocatalyst could follow a more appropriate Z-scheme charge transfer mechanism,which was confirmed by the analysis of experiment and theoretical calculation results.Wei Zhao Tiantian She Jingyi Zhang Guoxiang Wang Sujuan Zhang Wei Wei Gang Yang Lili Zhang Dehua Xia Zhipeng Cheng Haibao Huang Dennis Y.C.Leung 2021Journal of Materials Science & Technology2021,,26:3
16Insulin resistance and the metabolism of branched-chain amino acids显示文摘Insulin resistance(IR)is a key pathological feature of metabolic syndrome and subsequently causes serious health problems with an increased risk of several common metabolic disorders.IR related metabolic disturbance is not restricted to carbohydrates but impacts global metabolic network.Branched-chain amino acids(BCAAs),namely valine,leucine and isoleucine,are among the nine essential amino acids,accounting for 35%of the essential amino acids in muscle proteins and 40%of the preformed amino acids required by mammals.The BCAAs are particularly responsive to the inhibitory insulin action on amino acid release by skeletal muscle and their metabolism is profoundly altered in insulin resistant conditions and/or insulin deficiency.Although increased circulating BCAA concentration in insulin resistant conditions has been noted for many years and BCAAs have been reported to be involved in the regulation of glucose homeostasis and body weight,it is only recently that BCAAs are found to be closely associated with IR.This review will focus on the recent findings on BCAAs from both epidemic and mechanistic studies.Jingyi Lu Guoxiang Xie Weiping Jia Wei Jia 2013Frontiers of Medicine2013,7,1:3
17The role of watermelon caffeic acid O-methyltransferase (ClCOMT1) in melatonin biosynthesis and abiotic stress tolerance显示文摘Melatonin is a pleiotropic signaling molecule that regulates plant growth and responses to various abiotic stresses.The last step of melatonin synthesis in plants can be catalyzed by caffeic acid O-methyltransferase(COMT),a multifunctional enzyme reported to have N-acetylserotonin O-methyltransferase(ASMT)activity;however,the ASMT activity of COMT has not yet been characterized in nonmodel plants such as watermelon(Citrullus lanatus).Here,a total of 16 putative O-methyltransferase(ClOMT)genes were identified in watermelon.Among them,ClOMT03(Cla97C07G144540)was considered a potential COMT gene(renamed ClCOMT1)based on its high identities(60.00–74.93%)to known COMT genes involved in melatonin biosynthesis,expression in almost all tissues,and upregulation under abiotic stresses.The ClCOMT1 protein was localized in the cytoplasm.Overexpression of ClCOMT1 significantly increased melatonin contents,while ClCOMT1 knockout using the CRISPR/Cas-9 system decreased melatonin contents in watermelon calli.These results suggest that ClCOMT1 plays an essential role in melatonin biosynthesis in watermelon.In addition,ClCOMT1 expression in watermelon was upregulated by cold,drought,and salt stress,accompanied by increases in melatonin contents.Overexpression of ClCOMT1 enhanced transgenic Arabidopsis tolerance against such abiotic stresses,indicating that ClCOMT1 is a positive regulator of plant tolerance to abiotic stresses.Jingjing Chang Yanliang Guo Jingyi Yan Zixing Zhang Li Yuan Chunhua Wei Yong Zhang Jianxiang Ma Jianqiang Yang Xian Zhang Hao Li 2021Horticulture Research2021,8,1:2
18Rapid isolation and immune profiling of SARS-CoV-2 specific memory B cell in convalescent COVID-19 patients via LIBRA-seq显示文摘B cell response plays a critical role against SARS-CoV-2 infection.However,little is known about the diversity and frequency of the paired SARS-CoV-2 antigen-specific BCR repertoire after SARS-CoV-2 infection.Here,we performed single-cell RNA sequencing and VDJ sequencing using the memory and plasma B cells isolated from five convalescent COVID-19 patients,and analyzed the spectrum and transcriptional heterogeneity of antibody immune responses.Via linking BCR to antigen specificity through sequencing(LIBRA-seq),we identified a distinct activated memory B cell subgroup(CD11c^(high) CD95^(high))had a higher proportion of SARS-CoV-2 antigen-labeled cells compared with memory B cells.Our results revealed the diversity of paired BCR repertoire and the non-stochastic pairing of SARS-CoV-2 antigen-specific immunoglobulin heavy and light chains after SARS-CoV-2 infection.The public antibody clonotypes were shared by distinct convalescent individuals.Moreover,several antibodies isolated by LIBRA-seq showed high binding affinity against SARS-CoV-2 receptor-binding domain(RBD)or nucleoprotein(NP)via ELISA assay.Two RBD-reactive antibodies C14646P3S and C2767P3S isolated by LIBRA-seq exhibited high neutralizing activities against both pseudotyped and authentic SARS-CoV-2 viruses in vitro.Our study provides fundamental insights into B cell response following SARS-CoV-2 infection at the single-cell level.Bing He Shuning Liu Yuanyuan Wang Mengxin Xu Wei Cai Jia Liu Wendi Bai Shupei Ye Yong Ma Hengrui Hu Huicui Meng Tao Sun Yanling Li Huanle Luo Mang Shi Xiangjun Du Wenjing Zhao Shoudeng Chen Jingyi Yang Haipeng Zhu Yusheng Jie Yuedong Yang Deyin Guo Qiao Wang Yuwen Liu Huimin Yan Manli Wang Yao-Qing Chen 2021Signal Transduction and Targeted Therapy2021,6,6:2
19Relationship between time in range and corneal nerve fiber loss in asymptomatic patients with type 2 diabetes显示文摘Background: Corneal confocal microscopy (CCM) is a noninvasive technique to detect early nerve damage of diabetic sensorimotor polyneuropathy (DSPN). Time in range (TIR) is an emerging metric of glycemic control which was reported to be associated with diabetic complications. We sought to explore the relationship between TIR and corneal nerve parameters in asymptomatic patients with type 2 diabetes (T2DM).Methods: In this cross-sectional study, 206 asymptomatic inpatients with T2DM were recruited. After 7 days of continuous glucose monitoring, the TIR was calculated as the percentage of time in the glucose range of 3.9 to 10.0 mmol/L. CCM was performed to determine corneal nerve fiber density, corneal nerve branch density, and corneal nerve fiber length (CNFL). Abnormal CNFL was defined as ≤15.30 mm/mm2.Results: Abnormal CNFL was found in 30.6% (63/206) of asymptomatic subjects. Linear regression analyses revealed that TIR was positively correlated with CCM parameters both in the crude and adjusted models (all P< 0.05). Each 10% increase in TIR was associated with a 28.2% (95% CI: 0.595–0.866,P = 0.001) decreased risk of abnormal CNFL after adjusting for covariates. With the increase of TIR quartiles, corneal nerve fiber parameters increased significantly (allP for trend <0.01). The receiver operating characteristic curve indicated that the optimal cutoff point of TIR was 77.5% for predicting abnormal CNFL in asymptomatic patients.Conclusions: There is a significant independent correlation between TIR and corneal nerve fiber loss in asymptomatic T2DM patients. TIR may be a useful surrogate marker for early diagnosis of DSPN.Wejing Zhao Jingyi Lu Lei Zhang Wei Lu Wei Zhu Yuqian Bao Jjian Zhou 2022Chinese Medical Journal2022,135,16:2
