2基质金属蛋白酶1的组织抑制剂通过介导CD63与整合素β_1的相互作用促进心肌纤维化显示文摘心肌纤维化指细胞外基质纤维胶原蛋白的过度积累。纤维化是各种心肌病的关键特征,会影响心脏收缩和舒张功能。金属蛋白酶1组织抑制剂(tissue inhibitor of metalloproteinase-1,TIMP1)水平在心肌纤维化过程中始终增加,被认为是纤维化的标记物。Takawale A Zhang P Patel VB Wang X Oudit G Kassiri Z 刘莉 叶鹏 2017中华高血压杂志2017,25,4:13
3Through-needle all-optical ultrasound imaging in vivo: a preclinical swine study显示文摘High-frequency ultrasound imaging can provide exquisite visualizations of tissue to guide minimally invasive procedures.Here,we demonstrate that an all-optical ultrasound transducer,through which light guided by optical fibers is used to generate and receive ultrasound,is suitable for real-time invasive medical imaging in vivo.Broad-bandwidth ultrasound generation was achieved through the photoacoustic excitation of a multiwalled carbon nanotube-polydimethylsiloxane composite coating on the distal end of a 300-μm multi-mode optical fiber by a pulsed laser.The interrogation of a high-finesse Fabry–Pérot cavity on a single-mode optical fiber by a wavelength-tunable continuous-wave laser was applied for ultrasound reception.This transducer was integrated within a custom inner transseptal needle(diameter 1.08 mm;length 78 cm)that included a metallic septum to acoustically isolate the two optical fibers.The use of this needle within the beating heart of a pig provided unprecedented realtime views(50 Hz scan rate)of cardiac tissue(depth:2.5 cm;axial resolution:64μm)and revealed the critical anatomical structures required to safely perform a transseptal crossing:the right and left atrial walls,the right atrial appendage,and the limbus fossae ovalis.This new paradigm will allow ultrasound imaging to be integrated into a broad range of minimally invasive devices in different clinical contexts.Malcolm C Finlay Charles A Mosse Richard J Colchester Sacha Noimark Edward Z Zhang Sebastien Ourselin Paul C Beard Richard J Schilling Ivan P Parkin Ioannis Papakonstantinou Adrien E Desjardins 2017Light(Science & Applications)2017,6,1:6

5东方蜜蜂高效的卫生行为机制对于西方蜜蜂抗病育种的启示显示文摘西方蜜蜂(Apismellifera)在世界各地大范围的蜂群损失现象已引起科学界和公众的广泛关注,其健康状况与东方蜜蜂(Apis cerana)相比明显较劣。东方蜜蜂群内可检测到的病原体和寄生虫相对较少,即它们对于生物威胁具有更强的抵抗力,即便是面对异种入侵的新病原(如蜜蜂残翅病毒)。Lin Z Page P Li L Qin Y Zhang Y Hu F Neumann P Zheng H Dietemann V 蔺哲广 郑火青 胡福良 2016中国蜂业2016,67,12:5
6Nitrite-derived nitric oxide by xanthine oxidoreductase protects the liver against ischemia- reperfusion injury显示文摘It was demonstrated that xanthine oxidoreductase (XOR), during ischemia, catalyzes the formation of nitric oxide (NO) from nitrite (NO2-) and this NO2--derived NO protects the isolated perfused rat heart against the damaging effects of ischemia-reperfusion (I/R) when conventional nitric oxide synthase (NOS) -dependent NO production is impaired. Liver is one of the organs with the highest XOR concentration. This study was designed to determine whether NO2--derived NO by XOR protects liver against I/R injury in vivo. For its minute amounts and active reactivity, NO can not be detected directly in real time in vivo by this time. We have to prove the above hypothesis indirectly. METHODS:Wistar rats were pretreated with saline, NOS inhibitor L-NAME (10 mg/kg intravenously), XOR inhibitor allopurinol (1.5 mg/kg orally), L-NAME +allopurinol and NO scavenger carboxy-PTIO (0.6 mg/kg intravenously) respectively (12 animals per group). And then, they were subjected to total liver ischemia for 40 minutes followed by reperfusion. Blood samples and liver tissues were obtained for analysis after 3 hours of reperfusion. Survival was also investigated. RESULTS:Allopurinol-treated animals exhibited further increased serum alanine aminotransferase (ALT) levels and liver myeloperoxidase (MPO) activities, but further decreased liver adenosine triphosphate (ATP) stores after I/R compared to saline-treated counterparts (830.5±108.3 U/L, 56.5±11.0 U/mg protein and 1.93±0.47 μmol/g vs. 505.8± 184.2 U/L, 41.5±10.2 U/mg protein and 3.05±0.55 μmol/g respectively, P<0.01, P<0.05 and P<0.01 respectively). The hepatocyte injury was further exacerbated and the overall survival rate was significantly decreased after I/R in animals given by allopurinol compared to those pretreated by saline (P<0.05). L-NAME and allopurinol co-treated animals exhibited more severe liver injury (P<0.05 and P<0.01) and a further decreased overall survival rate (P<0.05) compared to L-NAME or allopurinol alone-treated counterparts, but they were not different from carboxy-PTIO treated animals (P>0.05). CONCLUSION:NO2--derived NO by XOR in the hypoxic and acidic environment induced by hepatic I/R protects the liver against I/R injury in vivo.Department of General Surgery ( Lu P, Wang CY and Chen DD), and Department of Radiology (Liu F), Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430022, China Cold Spring Harbor Laboratory, New York 11724, USA ( Yao Z) General Surgery Laboratory, Union Hospital, Tongji Medical College , Huazhong University of Science and Technology, Wuhan 430022 , China (Tian Y, Zhang JH and Wu YH) 2005Hepatobiliary & Pancreatic Diseases International2005,4,3:4

8纳米光子结构软膜紫外光固化纳米压印(英文)显示文摘紫外光固化纳米压印是实现纳米结构批量复制的一种新技术.其特点是低成本和高分辨,而且可以达到极高的套刻精度.为了得到大面积图案的均匀复制,可用聚二甲基硅氧烷(PDMS)制备透光的压印软模板.其母版图案可由高分辨率电子束曝光和反应离子刻蚀的方法在硅片基底上获得,然后用浇注的方法将图案转移到PDMS上.本实验特别发展了紫外光固化纳米压印适用于软膜压印的双层膜图型转移技术.该双层膜由廉价的光胶和聚甲基丙烯酸甲脂(PMMA)构成.对光胶层的压印可用普通的光学曝光仪实现.然后再将图案用反应离子刻蚀的方法转移到PMMA层中.为了证明方案的可行性,在两种不同材料的半导体基片上压印了三角晶格的光子晶体和准晶结构的图案,并用剥离的方法将它们转移到金属薄膜上,最后成功地进行了硅片刻蚀实验.相信这一纳米制做方法对大面积纳米光子结构和光学集成芯片的制造是普遍适用的.SHI J WANG Z M BAO K PEROZ C BELOTTI M XU L P LUO C X SUN M H ZHANG B JI H OUYANG Q CHEN Y 2006纳米技术与精密工程2006,4,3:2
