| 1 | Drug eluting biliary stents to decrease stent failure rates:Areview of the literature显示文摘Biliary stenting is clinically effective in relieving both malignant and non-malignant obstructions. However, there are high failure rates associated with tumor ingrowth and epithelial overgrowth as well as internally from biofilm development and subsequent clogging. Within the last decade, the use of prophylactic drug eluting stents as a means to reduce stent failure has been investigated. In this review we provide an overview of the current research on drug eluting biliary stents. While there is limited human trial data regarding the clinical benefit of drug eluting biliary stents in preventing stent obstruction, recent research suggests promise regarding their safety and potential efficacy. | Joseph Shatzel Jisoo Kim Kartik Sampath Sharjeel Syed Jennifer Saad Zilla H Hussain Kabir Mody J Marc Pipas Stuart Gordon Timothy Gardner Richard I Rothstein | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，2： | 6 |
| 2 | Nanoscopy reveals surface-metallic black phosphorus显示文摘Black phosphorus(BP)is an emerging two-dimensional material with intriguing physical properties.It is highly anisotropic and highly tunable by means of both the number of monolayers and surface doping.Here,we experimentally investigate and theoretically interpret the near-field properties of a-few-atomic-monolayer nanoflakes of BP.We discover near-field patterns of bright outside fringes and a high surface polarizability of nanofilm BP consistent with its surface-metallic,plasmonic behavior at mid-infrared frequencies o1176 cm−1.We conclude that these fringes are caused by the formation of a highly polarizable layer at the BP surface.This layer has a thickness of~1 nm and exhibits plasmonic behavior.We estimate that it contains free carriers in a concentration of n≈1.1×10^(20) cm^(−3).Surface plasmonic behavior is observed for 10–40 nm BP thicknesses but absent for a 4-nm BP thickness.This discovery opens up a new field of research and potential applications in nanoelectronics,plasmonics and optoelectronics. | Yohannes Abate Sampath Gamage Zhen Li Viktoriia Babicheva Mohammad H Javani Han Wang Stephen B Cronin Mark I Stockman | 2016 | Light(Science & Applications)2016，5，1： | 2 |
