| 1 | Biofilm Microenvironment-Responsive Nanotheranostics for Dual-Mode Imaging and Hypoxia-Relief-Enhanced Photodynamic Therapy of Bacterial Infections显示文摘The formation of bacterial biofilms closely associates with infectious diseases.Until now,precise diagnosis and effective treatment of bacterial biofilm infections are still in great need.Herein,a novel multifunctional theranostic nanoplatform based on MnO_(2)nanosheets(MnO_(2)NSs)has been designed to achieve pH-responsive dual-mode imaging and hypoxia-relief-enhanced antimicrobial photodynamic therapy(aPDT)of bacterial biofilm infections.In this study,MnO_(2)NSs were modified with bovine serum albumin(BSA)and polyethylene glycol(PEG)and then loaded with chlorin e_(6)(Ce_(6))as photosensitizer to form MnO_(2)-BSA/PEG-Ce_(6)nanosheets(MBP-Ce_(6)NSs).After being delivered into the bacterial biofilm-infected tissues,the MBP-Ce_(6)NSs could be decomposed in acidic biofilm microenvironment and release Ce_(6)with Mn^(2+),which subsequently activate both fluorescence(FL)and magnetic resonance(MR)signals for effective dual-mode FL/MR imaging of bacterial biofilm infections.Meanwhile,MnO_(2)could catalyze the decomposing of H2O_(2)in biofilm-infected tissues into O_(2)and relieve the hypoxic condition of biofilm,which significantly enhances the efficacy of aPDT.An in vitro study showed that MBP-Ce_(6)NSs could significantly reduce the number of methicillin-resistant Staphylococcus aureus(MRSA)in biofilms after 635nm laser irradiation.Guided by FL/MR imaging,MRSA biofilm-infected mice can be efficiently treated by MBP-Ce_(6)NSs-based aPDT.Overall,MBP-Ce_(6)NSs not only possess biofilm microenvironment-responsive dual-mode FL/MR imaging ability but also have significantly enhanced aPDT efficacy by relieving the hypoxia habitat of biofilm,which provides a promising theranostic nanoplatform for bacterial biofilm infections. | Weijun Xiu Siyu Gan Qirui Wen Qiu Qiu Sulai Dai Heng Dong Qiang Li Lihui Yuwen Lixing Weng Zhaogang Teng Yongbin Mou Lianhui Wang | 2020 | Research2020，，1： | 7 |
| 2 | Effect of nanometer-sized MgO particles on flux pinning in YBa_2Cu_30_(7-δ)显示文摘As is well known, the relatively low critical current density J_c and the serious flux motion limit a variety of applications of high-temperature superconductors (HTSCs).

| 3 | Transplantation Therapy of Cats with Chronic Renal Failure显示文摘Dialysis therapy is not a radical cure of chronic renal failure in cats,while renal transplantation is the cure method.Renal transplanta-tion requires rigorous examination of donor and receptor,and the procedure is strictly sterile.The main points of renal transplantation are:renal artery and vein sutured to abdominal aorta and posterior vena cava,respectively;ureter sutured to bladder;minimizing the time of thermal ischemia.Cats should be given immunosuppressant before the operation,and the drug should be administered throughout the life.Various indicators should be monitored regularly to prevent the occurrence of immunological rejection. | Zuo Kejing Huang Mian Tang Xiaojun Chen Xuanjiao Wen Yan Chen Tanzipeng Sa Jiaqi Liang Yuzhen Zhang Malong Peng Shiming Zhi Guanglin Wu Qirui | 2018 | Animal Husbandry and Feed Science2018，10，2： | 1 |
| 4 | Towards unraveling relationships in Xylariomycetidae(Sordariomycetes)显示文摘The classification of subclass Xylariomycetidae is revisited with additional collections and phylogeny based on novel rDNA sequence data.Phylogenetic inferences are provided and are based on analysis of 115 sequence data,including new data for 27 strains.An updated outline to the subclass is presented based on the phylogenies and comprises two orders,18 families and 222 genera.An account of each order,family and genus in the subclass is given.We accept the orders Amphisphaeriales and Xylariales based on morphological and phylogenetic evidence.Amphisphaeriales comprises Amphisphaeriaceae,Bartaliniaceae fam.nov.,Clypeosphaeriaceae,Discosiaceae fam.nov.,Pestalotiopsidaceae fam.nov.and Phlogicylindriaceae fam.nov.Xylariales comprises Apiosporaceae,Cainiaceae,Coniocessiaceae,Diatrypaceae,Graphostromataceae(doubtful),Hyponectriaceae,Iodosphaeriaceae,Lopadostomaceae fam.nov.,Melogrammataceae,Pseudomassariaceae fam.nov.,Vialaeaceae and Xylariaceae.The new genera and species introduced are Arthrinium hyphopodii,A.subglobosa,Cainia anthoxanthis,Ciferriascosea gen.nov.,C.fluctamurum,C.rectamurum,Discosia neofraxinea,D.pseudopleurochaeta,Hyalotiella rubi,Seimatosporium cornii,S.ficeae,S.vitis and Truncatella spartii. | Indunil C.Senanayake Sajeewa S.N.Maharachchikumbura Kevin D.Hyde Jayarama D.Bhat E.B.Gareth Jones Eric H.C.McKenzie Dong Qin Dai Dinushani A.Daranagama Monika C.Dayarathne Ishani D.Goonasekara Sirinapa Konta Wen Jing Li Qiu Ju Shang Marc Stadler Nalin N.Wijayawardene Yuan Pin Xiao Chada Norphanphoun Qirui Li Xing Zhong Liu Ali H.Bahkali Ji Chuan Kang Yong Wang Ting Chi Wen Lucile Wendt Jian Chu Xu Erio Camporesi | 2015 | Fungal Diversity2015，，4： | 0 |
