Dear Editor,Antibiotics are considered indispensable in numerous treatments against infectious ***,their over-prescription and widespread use are emerging as important global issues,as they lead to resistant bacteria,reducing the efficacy of antibiotics[1].The defined daily doses per 1,000 habitants per day for antibiotics in South Korea is 28,which is much higher than the average of Organization for Economic Co-operation and Development countries[1].In animal studies,antibiotic tigecycline was found to inhibit the proliferation and induce apoptosis of hepatocellular carcinoma(HCC)cells[2].In addition,isoprenoid antibiotic was found to suppress the growth and invasion of HCC by targeting the signal transducer and activator of the transcription 3 signaling cascade[3].Despite evidence of the beneficial effects of antibiotics against HCC,evidence regarding their effects on the longterm development of HCC is *** regarding the incidence of HCC is provided in the Supplementary file.

Fabrication of curved micro structures on photoresist layer

引用

Transactions of Nonferrous Metals Society of China 2011年第A1期21卷 100-103页

作者： Jae Sung YOON Tae-Jin JE Doo-Sun choi Sung hwan chang Kyung-Hyun WHANG Nano Mechanical Systems Research Division Korea Institute of Machinery and Materials (KIMM) Daejeon 305-343 Korea

A novel fabrication process for micro patterns with curvature was introduced. The curved structures were made by compensating rectangular micro structures with liquid photoresist layer. Because of the surface tension of the liquid in micro scale, various shapes of meniscus can be made on the micro channels. The micro channels were made on the silicon substrate in advance, and then the liquid layer was coated on the micro channels. From the nature of liquid behavior, the curved patterns with smooth surface are obtained, which cannot be made easily with the conventional mechanical machining, as well as with the microfabrication processes, such as wet and dry etching. With this principle, it is expected that the smooth and curved surfaces can be made by simple processes and the results can be applied widely, such as optical patterns.
