俯冲带大地震的机理受到板块边界断层的摩擦性质、地质构造和物质组成的影响。通过利用综合海洋钻探计划(Integrated Ocean Drilling Program,IODP)343和343T勘探结果,我们观测到2011年日本东北地区近海地震和海啸的较浅断层的地质构造和物质组成。随钻测井和岩心采样观测结果表明,在该钻探点,单个的主要板块边界断层与日本东北地区近海地震破裂的大型滑动相吻合,且与附近几乎所有累积的板内运动相一致。深海粘土有限厚度(小于5m)的局部形变被认为是浅层地震断层的特征,表明深海粘土可能在区域尺度上控制着海啸地震。

Meropenem, a carbapenem antibiotic, is inactive after oral administration and administered exclusively by injection. In this study, in order to address the factors involved in the oral inactivity of meropenem, in vitro permeation characteristics across rat ileal segments was investigated using diffusion cells. Moreover, stability of meropenem was evaluated in the Japanese Pharmacopoeia (JP) 1st and 2nd fluid for disintegration test. Cefotaxime, ceftibuten, and faropenem were used for comparison. The permeation of meropenem across rat ileal segments was approximately 5-fold greater in secretory direction than in absorptive direction. The secretory-oriented transport of meropenem markedly diminished by replacement of D-glucose in the experimental medium with unmetabolizing 3-O-methyl-D-glucose, suggesting that the secretory transport of meropenem was an energy-dependent process. Cefotaxime exhibited extensively secretory-oriented permeation. On the other hand, much weaker directionalities were observed in ceftibuten and faropenem. While meropenem as well as other three β-lactam antibiotics was stable in JP 2nd fluid (pH 6.8), it declined rapidly in JP 1st fluid (pH 1.2). These results suggest that, in addition to the hydrophilic property of meropenem, its instability at gastric pH and secretory transport in the small intestine are possible factors involved in the inactivity of meropenem after oral administration.

We reviewed basic considerations in fluid dynamics of cerebral aneurysms and applied these in surgery on the three most common types: internal carotid-posterior communicating artery,middle cerebral artery,and anterior communicating artery. It was found that aneurysmal initiation and growth do not occur at symmetric bifurcations. As blood flow always obeys the law of inertia,jet flow into the aneurysm will disperse along the wall; assuming the aneurysmal wall strength is even,the shape of the aneurysm becomes round or oval. When neurosurgeons encounter an aneurysm that is not round or oval,the wall may be fragile and requires great care during surgical manipulation.

日本的主要油、气田分布在日本海的本州北部(图1)。它们处于“绿色凝灰岩地区”(Fujite,1973,1990),区内的厚层热液蚀变火山碎屑岩,尤其是浅绿色长英质的到镁铁质的凝灰岩和凝灰角砾岩是早中新世时沉积的,覆盖这些沉积物的是中—晚中新世泥岩,包括硬化页岩、黑色页岩,及晚中新世至上新世的砂岩。石油几乎全部发现在那些上第三系沉积总厚度大于5000m的深埋的沉积盆地中的火山碎屑岩和砂岩储层中,并被认为是由这些沉积盆地的中—上中新统泥岩产生的。津轻盆地和那些油、气田一样处在同一个绿色凝灰岩地区,它位于秋田油区之北仅40km处(图1),津轻盆地的晚第三纪沉积的地层与秋田油区的非常相似,但是上第三系剖面的最大厚度仅约3000m,因而比秋田区的薄2000m。

Journal of Biomedical Science and Engineering 2012年第1期5卷 24-33页

作者： Ryoichi Ishii Hiromu Mori kenji Matsumura Norio Hongo Hiro kiyosue Shunro Matsumoto Takeshi Yoshimi Seiji ujiie Department of Radiology Faculty of Medicine Oita University

Purpose: The purpose of this study is to assess molecular interactions between several anticancer drugs and an iodinated contrast medium by Fourier transform infrared spectroscopy (FT-IR) and ultraviolet-visible spectroscopy (UV-Vis). Materials and Methods: Iopamidol (IPM) was used as an iodinated contrast medium, and mitomycin C (MTI), epirubicin hydrochloride (EPI), cisplatin (CDDP), 5-fluorouracil (5FU), irinotecan hydrochloride (CPT11), gemcitabine hydrochloride (dFdC), carboplatin (CBDCA), oxaliplatin (1OHP), paclitaxel hydrochloride (TAX) and docetaxel trihydrate (TXT) were used as anticancer drugs. For FT-IR, the purified IPM was mixed stoichiometrically with each anticancer drug as well as with a combination of MTI and EPI. After measuring each separated sample and the mixtures, the spectra of the mixtures were compared with the spectra of the sum of pure samples or the combination. For UV-Vis, IPM and anticancer drugs were dissolved in pure water;subsequently for the titration experiments, the mixtures were prepared by varying the molar ratio. IR absorption corresponds to stretching vibrations between atoms having covalent bonding, whereas UV-Vis spectra depend on molecular dynamics and shapes. Both UV-Vis and IR spectra change when there are molecular interactions such as aromatic ring stacking and hydrogen bonding. Result: IPM exhibited molecular interactions with MTI, EPI, CDDP, dFdC, CBDCA, 1OHP, TAX and TXT, as well as with the combination of MTI and EPI on FT-IR. However, molecular interactions were not observed on UV-Vis. Conclusion: Several anticancer drugs have molecular interactions with IPM, which could be clinically utilized for superselective intraarterial infusion chemotherapy.

Pyoderma gangrenosum(PG) is a neutrophilic dermatosis characterized by destructive,necrotizing and noninfective ulceration of the skin mostly on lower extremities PG is well known as a complication of Takayasus arteritis in Japan, However, this association is not commonly observed in North American and European patients We describe a case of PG that was associated with Takayasus arteritis who was successfully treated with systemic cyclosporin We have reviewed 35 well documented PG cases with Takayasus arteritis in comparison to 106 PG cases without Takayasus arteritis The results demonstrate that this association occurs pred ominantly in young females and that these cases exhibit more widespread PG
