World Journal of Gastrointestinal Endoscopy 2012年第11期4卷 489-499页

作者： Koji Nagata michio Shimizu Department of Pathology Saitama Medical University International Medical Center

Endoscopic surgery first started as snare polypectomy and then progressed to endoscopic mucosal resection (EMR). In order to resect a lesion that is more than 2 cm, endoscopic submucosal dissection (ESD) was developed. ESD therapy has now been established and is being used for early stage neoplastic lesions in the stomach, colon, esophagus, larynx and pharynx. In ESD specimens, we deal with relatively small lesions; therefore, more meticulous and precise pathological diagnosis is required compared to that in surgically resected specimens. In addition, we should be expert in the eligibility criteria of the different organs for ESD therapy. Here, we explain the biopsy diagnosis, including the Japanese group classification as well as the Vienna classification, handling the specimen, including fixation, photography, cutting and paraffin embedding, histological type, depth, vascular invasion and evaluation of the surgical margins, based on the latest Japanese guidelines. Japanese histopathology diagnostic criteria for the stomach, colon and esophagus are also described. We also demonstrate some examples of those mentioned above.

通过过热蒸气活化法制备的柏木炭中含有大量的中孔,可用于制备以1mol/L硫酸为电解液的双电层电容器(EDLCs)。在50mA/g电流密度下,柏木炭的质量比电容(C50)为190F/g;在1000mA/g电流密度下,其质量比电容(C1000)为140F/g。按C1000/C50定义的性能倍率约为0.72。测得的高电容量可归因于微孔和大孔所造成表面的贡献。以简易浸泡法负载少量NiO粒子后,柏木炭的质量比电容可以提高约13%,体积比电容提高约27%,而其性能倍率保持不变。

American Journal of Plant Sciences 2011年第1期2卷 52-55页

Some plant species traits may not be uniform across populations distributed across a wide latitudinal range. This study examined intraspecies variation in the effects of cold stratification on the germination of seeds of two widespread trees, Rhaphiolepis umbellata (Rosaceae) and Melia azedarach (Meliaceae), collected from the subtropical Ogasawara Islands (southern seeds) and the temperate Japan mainland (northern seeds). Under the no-treatment control, the southern seeds germinated faster in R. umbellata and achieved a higher germination percentage in M. azedarach. The regional differences in germination performance were reduced by cold stratification. It was reasonable that these germination traits increase fitness under each climate region. Because the remote Ogasawara populations are sufficiently isolated to have developed some distinct characteristics, even common, widespread species may have important conservation value where they exist within insular biota.

AIM To investigate the role of macrophage colony-stimulating factor(M-CSF) in patients with hepatocellular carcinoma(HCC) after surgery. METHODS Expression of M-CSF, distribution of M2 macrophages(Mφs), and angiogenesis were assessed in the liver, including tumors and peritumoral liver tissues. The prognostic power of these factors was assessed. Mouse isolated hepatic Mφs or monocytes were cultured with media containing M-CSF. The concentration of vascular endothelial growth factor(VEGF) in media was assessed. Furthermore, the role of the M-CSF-matured hepatic Mφs on proliferation of the vascular endothelial cell(VEC) was investigated. RESULTS A strong correlation between the expressions of M-CSF and CD163 was observed in the peritumoral area. Also, groups with high density of M-CSF, CD163 or CD31 showed a significantly shorter time to recurrence(TTR) than low density groups. Multivariate analysis revealedthe expression of M-CSF or hepatic M2Mφs in the peritumoral area as the most crucial factor responsible for shorter TTR. Moreover, the expression of M-CSF and hepatic M2Mφs in the peritumoral area had better predictable power of overall survival. Values of VEGF in culture media were significantly greater in the hepatic Mφs compared with the monocytes. Proliferation of the VEC was greatest in the cells co-cultured with hepatic Mφs when M-CSF was present in *** M-CSF increases hepatocarcinogenesis, most likely by enhancing an angiogenic factor derived from hepatic Mφ and could be a useful target for therapy against HCC.
