| 1 | Request Merging Based Cross-User Deduplication for Cloud Storage with Resistance Against Appending Chunks Attack显示文摘Cross-user deduplication is an emerging technique to eliminate redundant uploading in cloud storage.Its deterministic response indicating the existence of data creates a side channel to attackers,which makes the privacy in the cloud at risk.Such kind of attack as well as further appending chunks attack,still cannot be well resisted in current solutions,thus is becoming a big obstacle in using this technique.We propose a secure cross-user deduplication,called Request merging based deduplication scheme(RMDS),which takes the lead to consider resistance against appending chunks attack in a lightweight way,let alone side channel attack.We utilize the proposed XOR based chunk-level server-side storage structure together with a request merging strategy to obfuscate attackers in minimized communication overhead.The experiment results show that,with security guaranteed,the proposed scheme is more efficient comparing with the state of the art. | TANG Xin ZHANG Yi ZHOU Linna LIU Dan HU Bingwei | 2021 | Chinese Journal of Electronics2021，30，2： | 3 |

| 3 | Direct and single-step sensing of primary ovarian cancers related glycosidases显示文摘High sensitive,accurate detection for tumor-associated overexpressed enzyme activity is highly significant for further understanding enzyme function,discovering potential drugs,and early diagnosis and prevention of diseases.In this work,we developed a facile,direct and single-step detection platform for primary ovarian cancers related glycosidase activity based on the inner filter effect(IFE)between glycosidase catalytic product and black phosphorus quantum dots(BPQDs).Highly fluorescent BPQDs were successfully synthesized from bulk black phosphorus by a simple liquid exfoliation method.Under the catalysis ofβ-galactosidase,p-nitrophenyl-β-D-galactopyranoside(PNPG)was transformed into pnitrophenol(PNP)andβ-D-galactopyranoside.Meanwhile,the absorption of catalytic product PNP greatly overlapped with the excitation and emission spectra of fluorescent BPQDs,leading to the fluorescence quenching of BPQDs with a high quenching efficiency.The proposed sensing strategy provided a low detection limit of 0.76 U/L,which was 1-2 orders of magnitude lower than most unmodified sensing platforms.D-Galactal was selected as the inhibitor forβ-galactosidase to further assess the feasibility of screening potential inhibitors.The fluorescence recovery of BPQDs suggests that the unmodified sensing platform is feasible to discover potential drugs ofβ-galactosidase.Our work paves a general way in the detection of glycosidase activity with fluorescent BPQDs,which can be promising for glycosidase-related disease diagnosis and pathophysiology elucidation. | Dan Li Ling Liang Yawei Tang Linna Fu Shehua Xiao Quan Yuan | 2019 | Chinese Chemical Letters2019，30，5： | 2 |

| 8 | Electrochemical synthesis of dipyrazolo/dipyrimidine-fused pyridines via oxidative domino cyclization of C(sp^(3))–H bonds显示文摘An electrochemically oxidative domino cyclization reaction of methyl azaarenes/ketones with pyrazol-5-amines and 6-amino-pyrimidine-2,4-diones was developed, providing a variety of dipyrazolo[3,4-b:4’,3’-e]pyridines and dipyrimidine-fused pyridines with moderate to good yields. The reaction involved two C–C bond formations and one C–N bond formation in one pot. Moreover, the photoluminescence properties of the representative dipyrazolo[3,4-b:4’,3’-e]pyridines were investigated. | Peng Qian Linna Xu Wenyan Wang Lin Zhang Liang Tang Jiaojiao Liu Liangquan Sheng | 2022 | Organic Chemistry Frontiers2022，9，6： | 0 |
| 9 | H3K4me2/3 modulate the stability of RNA polymerase II pausing显示文摘Dear Editor,Modifications of histones are intricately linked with the regulation of gene expression,having demonstrated roles in various physiological processes and pathogenesis.Methylation of histone H3 lysine 4(H3K4)implemented by the COMPASS family is enriched at promoters and associated cis-regulatory elements,with H3K4 trimethylation(H3K4me3)being a hallmark of active gene promoters.1 However,the relative contributions of the deposition and removal of H3K4 methylation to transcriptional control remain unclear.We found that rapid depletion of core COMPASS subunits led to a dynamic turnover of H3K4me2 and H3K4me3 that is mediated by KDM5 demethylases.Depleting H3K4me2 and H3K4me3 did not affect TFIID recruitment or initiating RNA polymerase II(Pol II)but instead reduced levels of paused Pol II,which could be attributed to increased enrichment of the Integrator-PP2A complex(INTAC). | Shibin Hu Aixia Song Linna Peng Nan Tang Zhibin Qiao Zhenning Wang Fei Lan Fei Xavier Chen | 2023 | Cell Research2023，33，5： | 0 |
