1Intensifying Electron Utilization by Surface-Anchored Rh Complex for Enhanced Nicotinamide Cofactor Regeneration and Photoenzymatic CO_(2)Reduction显示文摘Solar-driven photocatalytic regeneration of cofactors,including reduced nicotinamide adenine dinucleotide(NADH),reduced nicotinamide adenine dinucleotide phosphate(NADPH),and reduced flavin adenine dinucleotide(FADH_(2)),could ensure the sustainable energy supply of enzymatic reactions catalyzed by oxidoreductases for the efficient synthesis of chemicals.However,the elevation of cofactor regeneration efficiency is severely hindered by the inefficient utilization of electrons transferred on the surface of photocatalysts.Inspired by the phenomenon of ferredoxin-NADP+reductase(FNR)anchoring on thylakoid membrane,herein,a homogeneous catalyst of rhodium(Rh)complex,[Cp_(∗)Rh(bpy)H_(2)O]^(2+),was anchored on polymeric carbon nitride(PCN)mediated by a tannic acid/polyethyleneimine(TA/PEI)adhesive layer,acquiring PCN@TA/PEI-Rh core@shell photocatalyst.Illuminated by visible light,electrons were excited from the PCN core,then transferred through the TA/PEI shell,and finally captured by the surface-anchored Rh for instant utilization during the regeneration of NADH.The TA/PEI-Rh shell could facilitate the electron transfer from the PCN core and,more importantly,achieved~1.3-fold elevation of electron utilization efficiency compared with PCN.Accordingly,the PCN@TA/PEI-Rh afforded the NADH regeneration efficiency of 37.8%after 20 min reaction under LED light(405 nm)illumination,over 1.5 times higher than PCN with free Rh.Coupling of the NADH regeneration system with formate dehydrogenase achieved continuous production of formate from carbon dioxide(CO_(2)).Our study may provide a generic and effective strategy to elevate the catalytic efficiency of a photocatalyst through intensifying the electron utilization.Yuqing Cheng Jiafu Shi Yizhou Wu Xueying Wang Yiying Sun Ziyi Cai Yu Chen Zhongyi Jiang 2021Research2021,,1:5
2In vitro study of enhanced photodynamic cancer cell killing effect by nanometer-thick gold nanosheets显示文摘Photodynamic therapy(PDT)by near-infrared(NIR)irradiation is a promising technique for treating various cancers.Here,we reported the development of free-standing wafer-scale Au nanosheets(NSs)that exhibited an impressive PDT effect.The Au NSs were synthesized by ionic layer epitaxy at the air-water interface with a uniform thickness in the range from 2 to 8.5 nm.These Au NSs were found very effective in generating singlet oxygen under NIR irradiation.In vitro cellular study showed that the Au NSs had very low cytotoxicity and high PDT efficiency due to their uniform 2D morphology.Au NSs could kill cancer cells after 5 min NIR irradiation with little heat generation.This performance is comparable to using 10 times mass loading of Au nanoparticles(NPs).This work suggests that two-dimensional(2D)Au NSs could be a new type of biocompatible nanomaterial for PDT of cancer with an extraordinary photon conversion and cancer cell killing efficiency.Ziyi Zhang Dalong Ni Fei Wang Xin Yin Shreya Goel Lazarus NGerman Yizhan Wang Jun Li Weibo Cai Xudong Wang 2020Nano Research2020,13,12:2
3Anomalous expression of chloride transporters in the sclerosed hippocampus of mesial temporal lobe epilepsy patients显示文摘The Na+-K+-Cl-cotransporter 1 and K+-Cl-cotransporter 2 regulate the levels of intracellular chloride in hippocampal cells.Impaired chloride transport by these proteins is thought to be involved in the pathophysiological mechanisms of mesial temporal lobe epilepsy.Imbalance in the relative expression of these two proteins can lead to a collapse of Cl-homeostasis,resulting in a loss of gamma-aminobutyric acid-ergic inhibition and even epileptiform discharges.In this study,we investigated the expression of Na+-K+-Cl-cotransporter 1 and K+-Cl-cotransporter 2 in the sclerosed hippocampus of patients with mesial temporal lobe epilepsy,using western blot analysis and immunohistochemistry.Compared with the histologically normal hippocampus,the sclerosed hippocampus showed increased Na+-K+-Cl-cotransporter 1 expression and decreased K+-Cl-cotransporter 2 expression,especially in CA2 and the dentate gyrus.The change was more prominent for the Na+-K+-Cl-cotransporter 1 than for the K+-Cl-cotransporter 2.These experimental findings indicate that the balance between intracellular and extracellular chloride may be disturbed in hippocampal sclerosis,contributing to the hyperexcitability underlying epileptic seizures.Changes in Na+-K+-Cl-cotransporter 1 expression seems to be the main contributor.Our study may shed new light on possible therapies for patients with mesial temporal lobe epilepsy with hippocampal sclerosis.Xiaodong Cai Libai Yang Jueqian Zhou Dan Zhu Qiang Guo Ziyi Chen Shuda Chen Liemin Zhou 2013Neural Regeneration Research2013,8,6:2
4Identification of publication characteristics and research trends in the management of gallbladder cancer显示文摘Background:To date,no comprehensive analysis of gallbladder cancer(GBC)management has been reported.We aimed to identify the publication characteristics and research trends in managing GBC over the past three decades.Methods:We selected the 100 most cited articles and performed a bibliometric analysis to summarize the publication characteristics,explore research hotspots,and identify research trends in the management of GBC.Results:The total citations of the included articles ranged from 123 to 1822.Period II(2001–2010)yielded the highest number of included articles,whereas the lowest was in Period III(2011–2020).The United States and Japan published the most papers,in which the Memorial Sloan–Kettering Cancer Center and Nagoya University were the leading institutions,respectively.The most influential authors were Blumgart LH and Fong YM from the United States.Cooperation among countries,institutions,and authors was weak.The Annals of Surgery contributed the most articles with the highest number of total citations.The most researched topic was surgery,followed by systemic therapy and adjuvant therapy.Since Period I,the percentage of surgery-related publications continuously decreased(Periods II and III versus Period I,both p<0.001),with a concomitant increase in those of adjuvant therapy(Period III versus Period I,p=0.004)and systemic therapy(Period II versus Period I,p=0.004;Period III versus Period I,p=0.002).Conclusions:Surgery remains the preferred treatment,while there is a tendency toward adjuvant and systemic therapy in GBC management.An increase in local and international collaboration for managing GBC is required.Jiasheng Cao Jiahao Hu Jiliang Shen Bin Zhang Win Topatana Shijie Li Tianen Chen Sarun Jeungpanich Yitong Tian Ziyi Lu Shuyou Peng Xiujun Cai Mingyu Chen 2022iLIVER2022,1,2:0
5SiRNA-mediated ankyrin-G silence modulates the expression of voltage-gated Na channels in murine hippocampal HT22 cells显示文摘Background:Voltage-gated sodium channels are the targets of many commonly used antiepileptic drugs.NaV1.6,encoded by Scn8a,increased in chronic mesial temporal epilepsy animal models and co-localized with Ankyrin-G,encoded by Ank3.We hypothesized that inhibition of Ank3 transcription by siRNA decrease the expression of NaV1.6.Results:We characterized expression of the target genes in hippocampal neuron HT22 cells by Real time-PCR.The melt peak in the resolution curve of Scn1a,Scn8a and Ank3 were all unique.Ank3 transcription was interfered and the relative Ank3 mRNA levels of the three interfered groups compared to GAPDH were 0.89±0.13,0.52±0.07 and 0.26±0.05 while that of the negative control group was 1.01±0.08(P<0.05).When Ank3 transcription was inhibited by siRNA,the relative mRNA levels of Scn8a decreased in the three groups(0.91±0.09,0.33±0.06 and 0.25±0.05),compared to the negative control group(1.10±0.09).Tested by Western blotting,protein levels of ankyrinG and Nav1.6 decreased after ank3-siRNA.Ankyrin-G in negative control group,group1,group2 and group1+2 were 0.813±0.051,0.744±0.041,0.477±0.055 and 0.351±0.190 respectively(P<0.01)while Nav1.6 were 0.934±0.036,0.867±0.078,0.498±0.070 and 0.586±0.180(P<0.01).The quantity analysis of immunofluorescence showed significant decrease of ankyrin-G and Nav1.6(Student’s test,P=0.046 and 0.016 respectively).Conclusion:We therefore concluded that in HT22 cells the expression of Nav1.6 was down-regulated by Ank3 RNA interference.Guanzhong Ni Xiaoting Hao Xiaodong Cai Jiaming Qin Liemin Zhou Patrick Kwan Ziyi Chen 2019Acta Epileptologica2019,1,1:0
6Effects of manufactured nanomaterials on algae:Implications and applications显示文摘The wide application of manufactured nanomaterials(MNMs)has resulted in the inevitable release of MNMs into the aquatic environment along their life cycle.As the primary producer in aquatic ecosystems,algae play a critical role in maintaining the balance of ecosystems’energy flow,material circulation and information transmission.Thus,thoroughly understanding the biological effects of MNMs on algae as well as the underlying mechanisms is of vital importance.We conducted a comprehensive review on both positive and negative effects of MNMs on algae and thoroughly discussed the underlying mechanisms.In general,exposure to MNMs may adversely affect algae’s gene expression,metabolites,photosynthesis,nitrogen fixation and growth rate.The major mechanisms of MNMs-induced inhibition are attributed to oxidative stress,mechanical damages,released metal ions and light-shielding effects.Meanwhile,the rational application of MNMs-algae interactions would promote valuable bioactive substances production as well as control biological and chemical pollutants.Our review could provide a better understanding of the biological effects of MNMs on algae and narrow the knowledge gaps on the underlying mechanisms.It would shed light on the investigation of environmental implications and applications of MNMs-algae interactions and meet the increasing demand for sustainable nanotechnology development.Yuxiong Huang Manyu Gao Wenjing Wang Ziyi Liu Wei Qian Ciara Chun Chen Xiaoshan Zhu Zhonghua Cai 2022Frontiers of Environmental Science & Engineering2022,16,9:0
7Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.Angel Abusleme Thomas Adam Shakeel Ahmad Sebastiano Aiello Muhammad Akram Nawab Ali Fengpeng An Guangpeng An Qi An Giuseppe Andronico Nikolay Anfimov Vito Antonelli Tatiana Antoshkina Burin

9RING finger 138 deregulation distorts NF-κB signaling and facilities colitis switch to aggressive malignancy显示文摘Prolonged activation of nuclear factor(NF)-кB signaling significantly contributes to the development of colorectal cancer(CRC).New therapeutic opportunities are emerging from targeting this distorted cell signaling transduction.Here,we discovered the critical role of RING finger 138(RNF138)in CRC tumorigenesis through regulating the NF-кB signaling,which is independent of its Ubiquitin-E3 ligase activity involved in DNA damage response.RNF138^(−/−) mice were hyper-susceptible to the switch from colitis to aggressive malignancy,which coincided with sustained aberrant NF-кB signaling in the colonic cells.Furthermore,RNF138 suppresses the activation of NF-кB signaling pathway through preventing the translocation of NIK and IKK-Beta Binding Protein(NIBP)to the cytoplasm,which requires the ubiquitin interaction motif(UIM)domain.More importantly,we uncovered a significant correlation between poor prognosis and the downregulation of RNF138 associated with reinforced NF-кB signaling in clinical settings,raising the possibility of RNF138 dysregulation as an indicator for the therapeutic intervention targeting NF-кB signaling.Using the xenograft models built upon either RNF138-dificient CRC cells or the cells derived from the RNF138-dysregulated CRC patients,we demonstrated that the inhibition of NF-кB signaling effectively hampered tumor growth.Overall,our work defined the pathogenic role of aberrant NF-кB signaling due to RNF138 downregulation in the cascade events from the colitis switch to colonic neoplastic transformation and progression,and also highlights the possibility of targeting the NF-кB signaling in treating specific subtypes of CRC indicated by RNF138-ablation.Yalan Lu Rong Huang Jianming Ying Xingchen Li Tao Jiao Lei Guo Haitao Zhou Han Wang Amannisa Tuersuntuoheti Jianmei Liu Qichen Chen Yanhong Wang Luying Su Changyuan Guo Fu Xu Ziyi Wang Yan Lu Kai Li Junbo Liang Zhen Huang Xiao Chen Jinjie Yao Hanjie Hu Xiaowen Cheng Yufeng Wan Xinyan Chen Ning Zhang Shiying Miao Jianqiang Cai Linfang Wang Changzheng Liu Wei Song Hong Zhao 2022Signal Transduction and Targeted Therapy2022,7,7:0
10The Warming of the Tibetan Plateau in Response to Transient and Stabilized 2.0℃/1.5℃Global Warming Targets显示文摘As 'the third pole', the Tibetan Plateau(TP) is sensitive to climate forcing and has experienced rapid warming in recent decades. This study analyzes annual and seasonal near-surface air temperature changes on the TP in response to transient and stabilized 2.0℃/1.5℃ global warming targets based on simulations of the Community Earth System Model(CESM). Elevation-dependent warming(EDW) with faster warming at higher elevations is predicted. A surface energy budget analysis is adopted to uncover the mechanisms responsible for the temperature changes. Our results indicate a clear amplified warming on the TP with positive EDW in 2.0℃/1.5℃ warmer futures, especially in the cold season. Mean TP warming relative to the reference period(1961–90) is dominated by an enhanced downward longwave radiation flux, while the variations in surface albedo shape the detailed pattern of EDW. For the same global warming level, the temperature changes under transient scenarios are ~0.2℃ higher than those under stabilized scenarios, and the characteristics of EDW are broadly similar for both scenarios. These differences can be primarily attributed to the combined effects of differential downward longwave radiation, cloud radiative forcing, and surface sensible and latent heat fluxes. These findings contribute to a more detailed understanding of regional climate on the TP in response to the long-term climate goals of the Paris Agreement and highlight the differences between transient and stabilized warming scenarios.Jintao ZHANG Qinglong YOU Fangying WU Ziyi CAI Nick PEPIN 2022Advances in Atmospheric Sciences2022,39,7:0
11An Optoelectronic thermometer based on microscale infrared-to-visible conversion devices显示文摘Thermometric detectors are crucial in evaluating the condition of target objects spanning from environments to the human body.Optical-based thermal sensing tools have received extensive attention,in which the photon upconversion process with low autofluorescence and high tissue penetration depth is considered as a competent method for temperature monitoring,particularly in biomedical fields.Here,we present an optoelectronic thermometer via infrared-to-visible upconversion,accomplished by integrated light receiving and emission devices.Fully fabricated thin-film,microscale devices present temperature-dependent light emission with an intensity change of 1.5%℃^(-1) and a spectral shift of 0.18 nm℃^(-1).The sensing mechanism is systematically characterized and ascribed to temperature dependent optoelectronic properties of the semiconductor band structure and the circuit operation condition.Patterned device arrays showcase the capability for spatially resolved temperature mapping.Finally,in vitro and in vivo experiments implemented with integrated fiber-optic sensors demonstrate real-time thermal detection of dynamic human activity and in the deep brain of animals,respectively.He Ding Guoqing Lv Xue Cai Junyu Chen Ziyi Cheng Yanxiu Peng Guo Tang Zhao Shi Yang Xie Xin Fu Lan Yin Jian Yang Yongtian Wang Xing Sheng 2022Light(Science & Applications)2022,11,6:0
