＜正＞EMBRYONIC FL0WER1（EMF1） together with EMF2 has very important role in the maintenance of vegetative development by repressing directly the flower organ identity genes in Arabidopsis. To investigate EMF1-mediated vegetative development, we have analyzed molecular function of EMF1-Interacting protein （EMF1IP） 1, 6, and 9 that had been isolated from yeast two-hybrid screen using EMF1 as bait, and are predicted to encode a MAP kinase （EMF1IP1）, zinc-finger protein （EMF1IP6） and a DnaJ-domain protein （EMF1IP9）, respectively. Using yeast two-hybrid system, it was revealed that middle region of EMF1 shows strong interaction only with the EMF1IP1, whereas C-terminal region of EMF1 shows the interaction with the EMF1IP6 and 9. We also found that C-terminal region of EMF1IP1 and N-terminal region of EMF1IP6 are involved in the interaction with EMF1, and entire EMF1IP9 is necessary for interaction with EMFl. Interestingly, the N-terminal region of EMF1IP6 includes B-box zinc-finger domain, indicating that the B-box zinc-finger might play an important role in the protein-protein interaction. As results of subcellular localization assay of EMF1IPs, it was suggested that EMF1IP1 is localized in nucleus, EMF1IP6 in both cytoplasm and nucleus, and EMF1IP9 in cytoplasm. In addition, experiments using EMF1IPs::GUS and semi-quantitative RT-PCR analysis revealed that EMF1 was expressed during most of vegetative developmental stages after germination, but not in floral clusters including inflorescence meristem. Especially EMF1 was strongly expressed during early growth stage of vegetative development. EMF1IPs were detected in all of developmental stages investigated except at 4 days after germination （DAG）, but differential expressions were observed during the developmental stages after 4 DAG These expression patterns suggest that the interaction between EMF1 and EMF1IPs might strongly occur during early growth stage. Taken together, our results suggest that the interaction between E

Evaluation of particle growth systems for sampling and analysis of atmospheric fine particles

Particuology 2011年第6期9卷 606-610页

作者： Dae Seong Kim Sang bum Hong Jung-Taek Kwon Kihong park Department of Environmental Science and Engineering Gwangju Institute of Science and Technology Korea Polar Research Institute Laboratory of Toxicology College of Veterinary Medicine Seoul National University

Three types of water-based condensational growth systems, which can enable particles to grow in size to facilitate sampling and subsequent chemical analysis, were evaluated. The first one is a mixing type growth system where aerosols are mixed with saturated water vapor, the second one is a thermal diffusive growth system where warm flow enters cold-walled tube, and the third one is a laminar flow type where cold flow enters a warm wet-wall tube. Hygroscopic sodium chloride （NaCl）, ammonium sulfate （（NH4）2SO4） and ammonium nitrate （NH4N03）, and non-hygroscopic polystyrene latex （PSL） particles, in the size range of 50-400 nm, were used to determine their growth factors through the growth systems. Our data showed that the third-type growth system could enable particles to grow most efficiently regardless of their hygroscopic property. Collection efficiency of particles in the size range of 0.05-2.5 μm, in a continuous aerosol sampler after they passed through the third-type growth system was about 100%, suggesting that the third-type growth system would he the most useful among the tested growth systems for sampling and subsequent chemical analysis of fine and ultrafine particles.

EGC was defined as malignant lesions that do not invade beyond the submucosal layer of the stomach wall irrespective of presence of lymph node ***: Among 2270 enrolled patients, LNM was observed in 217(9%) patients. LNM in intramucosal(M) cancer and submucosal(SM) cancer was detectedin 3 8( 2. 8 %, 3 8 / 1 3 4 0) patients and 1 7 9(19%, 179/930) patients, respectively. In univariate analysis, the risk factors for LNM in EGC were size of tumor, Lauren classification, ulcer, lymphatic invasion, vascular invasion, and depth of invasion. However, in multivariate analysis, size of tumor, lymphatic invasion, vascular invasion, and depth of invasion were risk factors for LNM in EGC. Size of tumor, lymphatic invasion, vascular invasion, and depth of invasion were risk factors for LNM in cases of intramucosal cancer and submucosal cancer. In particular, there was no lymph node metastasis in cases of well differentiated early gastric cancer below 1 cm in size without ulcer regardless of lymphovascular ***: Tumor size, perilymphatic-vascular invasion, and depth of invasion were risk factors for LNM in EGC.

Major hepatectomy using the glissonean approach in cases of right umbilical portion

引用

World Journal of Hepatology 2016年第34期8卷 1535-1540页

作者： Yusuke Ome Kazuyuki Kawamoto Tae bum park Tadashi Ito Department of Surgery Kurashiki Central Hospital

Right umbilical portion(RUP) is a rare congenital anomaly associated with anomalous ramifications of the hepatic vessels and biliary system. As such, major hepatectomy requires a careful approach. We describe the usefulness of the Glissonean approach in two patients with vessel anomalies, such as RUP. The first patient underwent a right anterior sectionectomy for intrahepatic cholangiocarcinoma. We encircled several Glissonean pedicles that entered the right anterior section along the right side of the RUP. We temporarily clamped each pedicle, confirmed the demarcation area, and finally cut them. The operation was performed safely and was successful. The second patient underwent a left trisectionectomy for perihilar cholangiocarcinoma. We secured the right posterior Glissonean pedicle. The vessels in the pedicle were preserved, and the other vessels and contents were resected. Identifying the vessels for preservation facilitated the safe lymphadenectomy and dissection of the vessels to be resected. We successfully performed the operation.

Bird-mimetic Wing System of Flapping-wing Micro Air Vehicle with Autonomous Flight Control Capability

引用

Journal of Bionic Engineering 2016年第3期13卷 458-467页

作者： Sriyulianti Widhiarini Ji Hwan park bum Soo Yoon Kwang Joon Yoon ll-Hyun Paik Jong Heon Kim Chan Yik park Seung Moon Jun Changho Nam Department of Aerospace Engineering Konkuk University Gwangjin-gu Seoul South Korea Deptartment of PGM Technology Hanwha Corp. R&D Center Daejeon South Korea Agency for Defense Development Daejeon South Korea Department of Engineering Technology Arizona State University Mesa Arizona

A micro air vehicle with a bird-mimetic up-down and twisting wing drive system was developed in this study. The Flap- ping-wing Micro Air Vehicle （FMAV）, with a 50 cm wingspan and a double-crank drive system, performed successful flights of up to 23 min. The performance and capabilities of the FMAV were enhanced by adapting a number of unique features, such as a bird-mimetic wing shape with a span-wise camber and an up-down and twisting wing drive mechanism with double-crank linkages, This lift-enhancing design by mimicking the flapping mechanism of a bird＇s wing enabled the 210 g FMAV to fly autonomously in an outdoor field under wind speeds of less than 5 m.s-1. Autonomous flight was enabled by installing a flight control computer with a micro-electro-mechanical gyroscope and accelerometers, along with a micro video camera and an ultralight wireless communication system inside the fuselage. A comprehensive wind tunnel test shows that the FMAV with a high-camber wing and double-crank mechanism generates more lift and less net thrust than the FMAV with a flat wing and single-crank mechanism, which confirms the improved performance of the developed FMAV, as well as the superior slow flying or hovering capabilities of the FMAV with a high-camber wing and double-crank wing drive system.
