1The involvement of wheat U-box E3 ubiquitin ligase TaPUB1 in salt stress tolerance显示文摘U-box E3 ubiquitin ligases play important roles in the ubiquitin/26 S proteasome machinery and in abiotic stress responses. Ta PUB1-overexpressing wheat(Triticum aestivum L.) were generated to evaluate its function in salt tolerance. These plants had more salt stress tolerance during seedling and flowering stages, whereas the Ta PUB1-RNA interference(RNAi)-mediated knock-down transgenic wheat showed more salt stress sensitivity than the wild type(WT). Ta PUB1 overexpression upregulated the expression of genes related to ion channels and increased the net root Na+efflux, but decreased the net K+efflux and H+influx, thereby maintaining a low cytosolic Na+/K+ratio, compared with the WT. However,RNAi-mediated knock-down plants showed the opposite response to salt stress. Ta PUB1 could induce the expression of some genes that improved the antioxidant capacity of plants under salt stress. Ta PUB1 also interacted with Ta MP(Triticum aestivum α-mannosidase protein), a regulator playing an important role in salt response in yeast and in plants. Thus, low cytosolic Na+/K+ratios and better antioxidant enzyme activities could be maintained in wheat with overexpression of Ta PUB1 under salt stress. Therefore, we conclude that the U-box E3 ubiquitin ligase Ta PUB1 positively regulates salt stress tolerance in wheat.Wenlong Wang Wenqiang Wang Yunzhen Wu Qinxue Li Guangqiang Zhang Ruirui Shi Junjiao Yang Yong Wang Wei Wang 2020Journal of Integrative Plant Biology2020,62,5:6
2Redox dual-stimuli responsive drug delivery systems for improving tumor-targeting ability and reducing adverse side effects显示文摘Cancer is a big challenge that has plagued the human beings for ages and one of the most effective treatments is chemotherapy. However, the low tumor-targeting ability limits the wide clinical application of chemotherapy. The microenvironment plays a critical role in many aspects of tumor genesis. It generates the tumor vasculature and it is highly implicated in the progression to metastasis. To maintain a suitable environment for tumor progression, there are special microenvironment in tumor cell, such as low pH, high level of glutathione(GSH) and reactive oxygen species(ROS), and more special enzymes, which is different to normal cell. Microenvironment-targeted therapy strategy could create new opportunities for therapeutic targeting. Compared to other targeting strategies, microenvironment-targeted therapy strategy will control the drug release into tumor cells more accurately. Redox responsive drug delivery systems(DDSs) are developed based on the high level of GSH in tumor cells. However, there are also GSH in normal cell though its level is lower. In order to control the release of drugs more accurately and reduce side effects, other drug release stimuli have been introduced to redox responsive DDSs. Under the synergistic reaction of two stimuli, redox dual-stimuli responsive DDSs will control the release of drugs more accurately and quickly and even increase the accumulation. This review summarizes strategies of redox dual-stimuli responsive DDSs such as pH, light, enzyme, ROS, and magnetic guide to delivery chemotherapeutic agents more accurately, aiming at providing new ideas for further promoting the drug release,enhancing tumor-targeting and improving anticancer effects. To better illustrate the redox dual-stimuli responsive DDS, preparations of carriers are also briefly described in the review.Ruirui Li Feifei Peng Jia Cai Dandan Yang Peng Zhang 2020Asian Journal of Pharmaceutical Sciences2020,15,3:5
3Application of red mud as a basic catalyst for biodiesel production显示文摘Red mud was investigated in triglyceride transesterification with a view to determine its viability as a basic catalyst for use in biodiesel synthesis.The effect of calcination temperature on the structure and activity of red mud catalysts was investigated.It was found that highly active catalyst was obtained by simply drying red mud at 200°C.Utilization of red mud as a catalyst for biodiesel production not only provides a cost-effective and environmentally friendly way of recycling this solid red mud waste,significantly reducing its environmental effects,but also reduces the price of biodiesel to make biodiesel competitive with petroleum diesel.Qiang Liu Ruirui Xin Chengcheng Li Chunli Xu Jun Yang 2013Journal of Environmental Sciences2013,25,4:5
4Cerebral fractional amplitude of low-frequency fluctuations may predict headache intensity improvement following acupuncture treatment in migraine patients显示文摘OBJECTIVE:To explore how baseline resting-state cerebral function predicts clinical outcomes of acupuncture treatment for migraine.METHODS:One hundred migraine patients and 46 healthy subjects were recruited.Patients were randomized into the acupuncture,sham acupuncture,and waiting list groups.Resting-state functional magnetic resonance imaging data were collected at baseline and after 1 month of longitudinal acupuncture treatments.Fractional amplitude of low-frequency fluctuations(f ALFF)calculations were applied to explore the associations between baseline f ALFF and changes in clinical variables in the acupuncture treatment group and the waiting list group.RESULTS:Compared with healthy subjects,migraine patients had lower f ALFF in the left rostral ventromedial medulla,right thalamus,left amygdala,and right angular gyrus.Regression analyses revealed that baseline f ALFF values in the left middle frontal gyrus,left superior temporal gyrus,and middle temporal gyrus were positively associated with headache intensity changes in the acupuncture treatment group,while baseline f ALFF values in the bilateral lingual gyrus and cuneus were negatively associated with headache intensity changes in this group.CONCLUSION:The baseline f ALFF values of brain regions associated with cognitive pain modulation,but not migraine severity,may predict future headache intensity improvement levels in migraine patients receiving acupuncture treatment.Li Zhengjie Zhou Jun Cheng Shirui Lan Lei Sun Ruirui Liu Mailan Yang Jie Gao Yujie Guo Taipin Gong Qiyong Zeng Fang Liang Fanrong 2020Journal of Traditional Chinese Medicine2020,40,6:5

6Energy-level dependent H_2_O_2 production on metal-free,carbon-content tunable carbon nitride photocatalysts显示文摘Light-driven production of H_2O_2 from water and molecular oxygen could be a promising way for obtaining both solar fuels and fundamental chemicals. During that process, the H_2O_2 yield is strongly dependent on the reaction pathway associated with two-electron reduction of dioxygen by the photo-generated electrons. Herein, we synthesized a series of metal-free, carbon-content tunable carbon nitride photocatalysts(named C_3N_4-Carbon) by a facile hydrothermal reaction and subsequent thermal treatment at appropriate temperatures. The energy levels of the C_3N_4-Carbon catalysts vary with the carbon doping level, which is conveniently tuned by changing the initial glucose concentration during the hydrothermal reaction. The surface carbon species evolve with the carbon content and the nitrogen atoms in the structure of carbon nitride are partially substituted by foreign carbon atoms based on XPS measurements. The optimal catalyst leads to the highest H_2O_2 yield of 1271 μmol L^(-1) in an acidic aqueous solution(pH 3) after a reaction period of 4 h, twice higher than the pristine C_3N_4. In addition, the largest formation rate constant and the smallest decomposition rate constant of H_2O_2 are obtained on the optimal one according to the kinetics analyses. The decomposition tests of H_2O_2 indicate that the formation rate could be a dominant factor impacting the H_2O_2 yield. The conduction band position of the optimal catalyst is positively shifted to 0.06 V versus RHE, which is more favorable to the reduction of dioxygen to H_2O_2(O2/H_2O_2 at 0.69 V versus RHE). The positive shift of valence band also improves hole collection and leads to enhanced formation of H_2O_2.Ruirui Wang Xin Zhang Fan Li Ding Cao Min Pu Dandan Han Junjiao Yang Xu Xiang 2018Journal of Energy Chemistry2018,27,2:4
7UWB Channel Modeling and Simulation with Continuous Frequency Response显示文摘Ultra-wideband(UWB)technology is a prospective technology for high-rate transmission and accurate localization in the future communication systems.State-of-art channel modeling approaches usually divide the UWB channel into several sub-band channels and model them independently.By considering frequency-dependent channel parameters,a novel analytical UWB channel model with continuous frequency response is proposed.The composite effect of all frequency components within the UWB channel on the channel impulse response(CIR)of delay domain is derived based on the continuous channel transfer function(CTF)of frequency domain.On this basis,a closed-form simulation model for UWB channels and geometry-based parameter calculation method are developed,which can guarantee the continuity of channel characteristics on the frequency domain and greatly reduce the simulation complexity.Finally,the proposed method is applied to generate UWB channel with 2 GHz bandwidth at sub-6GHz and millimeter wave(mmWave)bands,respectively.The channel measurements are also carried out to validate the proposed method.The simulated CIR and power gain are shown to be in good agreement with the measurement data.Moreover,the comparison results of power gain and Doppler power spectral density(DPSD)show that the proposed UWB channel model Received:Apr.23,2022 Revised:Jun.09,2022 Editor:Wei Fan achieves a good balance between the simulation accuracy and efficiency.Kai Mao Qiuming Zhu Xijuan Ye Ruirui Feng Fuqiao Duan Yang Miao Maozhong Song 2022China Communications2022,19,11:3
8Evolution from small molecule to nano-drug delivery systems:An emerging approach for cancer therapy of ursolic acid显示文摘Ursolic acid(UA),a natural pentacyclic triterpenoid,possesses widespread biological and pharmacological activities.However,drawbacks such as low bioavailability,poor targeting and rapid metabolism greatly hinder its further clinical application.Recently,with the development of nanotechnology,various UA nanosystems have emerged as promising strategies for effective cancer therapy.This article reviews various types of UA-based nanodelivery systems,primarily with emphasis placed on novel UA-based carrier-free nanodrugs,which are considered to be innovative methods for cancer therapy.Moreover,this review presents carrier-free nano-drugs that co-assembled of UA and photosensitizers that displayed synergistic antitumor performance.Finally,the article also describes the development and challenges of UA nanosystems for future research in this field.Overall,the information presented in this review will provide new insight into the rational utilization of nano-drugs in cancer therapy.Jingwei Shao Yifan Fang Ruirui Zhao Fangmin Chen Mingyue Yang Jiali Jiang Zixuan Chen Xiaotian Yuan Lee Jia 2020Asian Journal of Pharmaceutical Sciences2020,15,6:3
9Tuning the luminous properties and optical thermometry of Cs_(2)SnCl_(6) phosphor microcrystals via Bi and Sb codoping显示文摘The toxicity and instability of lead halide perovskite seriously limit its commercial application in lighting,although it has high photoluminescence(PL)efficiency and adjustable emission.Here,lead-free bismuth(Bi)and antimony(Sb)codoped Cs_(2)SnCl_(6)(BSCSC)microcrystals(MCs)are prepared successfully by a solvothermal method.The PL spectrum is composed of dual emission bands with the peak at 485 and 650 nm,of which relative intensity can be tunable through the change of Bi and Sb feeding contents,respectively.Because of the phonon–electron interaction,the PL intensity is enhanced as the temperature rises within the range of 80–260 K.Then,the nonradiative transition is intensified until 380 K,which results in decrease in PL intensity.Simultaneously,combining with time-resolved PL,it is concluded that the emission peak at 485 nm is attributed to the[Bi_(Sn)+V_(Cl)]as the luminescent centers with the lifetime of hundreds of nanoseconds,and the emission peak at 650 nm is attributed to microsecond-timescale self-trapped excitons.The maximum values of relative sensitivity(S_(R))and absolute sensitivity(S_(A))values obtained are 3.82%K^(-1) and 5.11 ns·K^(-1),which for the first time to our knowledge demonstrate that BSCSC MCs can be novel luminescent materials for developing better optical thermometry.Whitelight-emitting diodes(WLEDs)are constructed using BSCSC MCs only combined with an LED chip,the Commission Internationale de L’Eclairage color coordinates of which are(0.30,0.37).It provides a novel scheme for the lighting field to realize WLEDs without adding additional commercial phosphors.SHUNFA GONG RUIRUI WU SEN YANG LIFANG WU MINMIN ZHANG QIUJU HAN WENZHI WU 2021Photonics Research2021,9,11:2
10Secondary donor-derived CD19 CAR-T therapy is safe and efficacious in acute lymphoblastic leukemia with extramedullary relapse after first autologous CAR-T therapy显示文摘Despite the advancement of treatments,adults with relapsed/refractory(R/R)B-lineage acute lymphoblastic leukemia(B-ALL)have poor prognosis,with an expected five-year overall survival(OS)rate of 10%‒20%(Nguyen et al.,2008;Oriol et al.,2010).Extramedullary relapse of B-ALL is regarded as a highrisk factor generally associated with poor survival,occurring in about 15%to 20%of all relapsed patients(Ding et al.,2017;Sun et al.,2018).The central nervous system(CNS)and the testes are the most common sites of extramedullary relapse of B-ALL.In addition,extramedullary leukemia can appear in the skin,eyes,breasts,bones,muscles,and abdominal organs.The prognosis of relapsed extramedullary B-ALL after allogeneic hematopoietic stem cell transplantation(allo-HSCT)is extremely poor(Spyridonidis et al.,2012;Dahlberg et al.,2019).Conventional chemotherapy or radiation is often ineffective in such patients.At present,there are no optimal treatment strategies for treating extramedullary leukemia after allo-HSCT.Delin KONG Tingting YANG Jia GENG Ruirui JING Qiqi ZHANG GuoqingWEI He HUANG Yongxian HU 2022Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2022,23,10:2
11Stability,acidity and interaction properties of [Bmim][SbF_6] coupled with concentrated sulfuric acid显示文摘Ionic liquid coupled with strong acid systems presents considerable promise in some catalytic fields.In the present work,the multiple complex systems composed by 98 wt%concentrated sulfuric acid and[Bmim][SbF_6]were investigated in the terms of stability,acidity and interaction properties.It was found that acidolysis of[Bmim][SbF_6]occurred in the 98 wt%concentrated sulfuric acid accompanied by HF releasing and SbF_6~ degrading to[SbF_(6-y)XHSO_4]_y]^-.The species after acidolysis in the multiple complex systems were checked and confirmed by electrospray ionization mass spectrometry(ESI-MS),Fourier transform infrared spectroscopy(FT-IR),~1H NMR and ^(19)F NMR.Acidity increased slightly with less than 1 wt%[Bmim][SbF_6]addition,while decreased with more proportion,which was determined based on the Hammett acidity functions H_0,using ^(13)C NMR.The strong hydrogen bond S-O-H…F of interaction among the multiple complex systems was confirmed by molecular dynamic simulation.Honghua Zhang Ruixia Liu Ruirui Zhang Feng Huo Zhiqiang Yang Bin He Suojiang Zhang Yanji Wang 2017Science China Chemistry2017,60,9:2
12Comparative catalytic study on butene/isobutane alkylation over LaX and CeX zeolites: The influence of calcination atmosphere显示文摘Lanthanum-containing(LaX)and cerium-containing X zeolites(CeX)were prepared by a doubleexchange,double-calcination method.By changing the calcination atmospheres between nitrogen and air,the Ce^(IV) contents in CeX zeolites were adjusted and their impacts on physicochemical properties and catalytic performance in isobutane alkylation were established.The crystallinity of CeX zeolite was found to be negatively correlated with the Ce^(IV) content.This i s believed to be due to the water formed during the oxidation of Ce^(III),which facilitates the framework dealumination.As a consequence,calcining in air resulted in a great elimination of strong Brønsted acid sites while under nitrogen protection,this phenomenon was mostly hindered and the sample’s acidity was preserved.When tested in a continuously flowed slurry reactor,the catalyst lifetime for isobutane alkylation was found to be linearly related to the strong Brønsted acid concentration.In addition,Ce^(3+)was found more benefit for the hydride transfer compared with La^(3+),which is ascribed to the stronger polarization effect on the CH bond of isobutane.Moreover,the decline of hydride transfer activity can be slowed down by the catalytic cracking of the bulky molecules.Based on the product distribution,a new catalytic cycle of dimethylhexanes(DMHs)involving a direct formation of isobutene rather than tert-butyl carbocation was proposed in isobutane alkylation.Zhiqiang Yang Ruirui Zhang Honghua Zhang Hongguo Tang Ruixia Liu Suojiang Zhang 2022Chinese Journal of Chemical Engineering2022,35,6:2

17Pharmacological inhibition of BAP1 recruits HERC2 to competitively dissociate BRCA1-BARD1, suppresses DNA repair and sensitizes CRC to radiotherapy显示文摘Radiotherapy is widely used in the management of advanced colorectal cancer(CRC).However,the clinical efficacy is limited by the safe irradiated dose.Sensitizing tumor cells to radiotherapy via interrupting DNA repair is a promising approach to conquering the limitation.The BRCA1-BARD1 complex has been demonstrated to play a critical role in homologous recombination(HR)DSB repair,and its functions may be affected by HERC2 or BAP1.Accumulated evidence illustrates that the ubiquitination-deubiquitination balance is involved in these processes;however,the precise mechanism for the cross-talk among these proteins in HR repair following radiation hasn’t been defined.Through activity-based profiling,we identified PT33 as an active entity for HR repair suppression.Subsequently,we revealed that BAP1 serves as a novel molecular target of PT33 via a CRISPR-based deubiquitinase screen.Mechanistically,pharmacological covalent inhibition of BAP1 with PT33 recruits HERC2 to compete with BARD1 for BRCA1 interaction,interrupting HR repair.Consequently,PT33 treatment can substantially enhance the sensitivity of CRC cells to radiotherapy in vitro and in vivo.Overall,these findings provide a mechanistic basis for PT33-induced HR suppression and may guide an effective strategy to improve therapeutic gain.Xin Yue Tingyu Liu Xuecen Wang Weijian Wu Gesi Wen Yang Yi Jiaxin Wu Ziyang Wang Weixiang Zhan Ruirui Wu Yuan Meng Zhirui Cao Liyuan Le Wenyan Qiu Xiaoyue Zhang Zhenyu Li Yong Chen Guohui Wan Xianzhang Bu Zhenwei Peng Ran-yi Liu 2023Acta Pharmaceutica Sinica B2023,13,8:1
