Granulocyte colony-stimulating factor(G-CSF)-producing tumor is one of the rare types of cancer clinically characterized by an elevated fever and white blood cell(WBC) increment. Although G-CSF producing tumors have been reported in several types of cancer including those of the lungs, cervix and bladder, G-CSF producing hepatocellular carcinoma is extremely rare. Here, we report the case of a rapidly growing and poorly differentiated hepatocellular carcinoma producing G-CSF. The patient showed symptoms of continuous high fever, stomach pain and cough, and high serum WBC counts, C-reactive protein(CRP) and G-CSF levels were found in laboratory tests. After a radical hepatectomy, the patient completely recovered from the above symptoms and inflammatory state. The serum levels of G-CSF were reduced to normal levels after radical surgery. An immunohistochemical analysis revealed the overexpression of G-CSF in the cytoplasm of certain hepatocellular carcinoma(HCC) cell. The patient's serum WBC, CRP and G-CSF levels remained within normal levels in the six months after surgery without recurrence. This is the 9^(th) case report of G-CSF producing hepatocellular carcinoma in English literature. We review the clinical characteristics of the G-CSF producing HCC and discuss a possible treatment strategy.

历来学界对朱熹“格物致知”论的理解并不一致。有“认识论”脉络的诠释,也有“心性论”脉络的诠释。在朱熹“格物致知”论中,“格物”的第一阶段是以外在事物为对象而究明“所当然之则”的工夫,所以确实可以从“认识论”脉络解读它;但到了究明“所以然之故”的第二阶段,外物之理与内心之理相通,“格物”成为“知性”,因此无法单纯地将它规定为现代认识论脉络的“求知”活动。关于“致知”,其工夫的对象、舞台不是外在物理,而是内在心理,因此无法从认识论脉络解读它。朱熹所理解的“知”是人心先天具有的本体之性(理)展现为作用之情的灵妙机能,换言之,即“明德”或“良知”。因此,关于“知”的基本意涵以及“知至”的境界,可以说朱熹与阳明的理解是一致的。吾人不能轻易地将朱熹脉络的“格物致知”与阳明脉络的“致良知”视为完全对立、矛盾的工夫。

Aszonapyrone A Isolated from Neosartorya spinosa IFM 47025 Inhibits the NF-κB Signaling Pathway Activated by Expression of the Ependymoma-Causing Fusion Protein ZFTA-RELA

引用

Advances in Microbiology 2024年第9期14卷 448-467页

作者： Kazuki Ishikawa Nao Kamiya Masaki ishii Takashi Yaguchi Koji Ichinose Shinya Ohata Faculty of Pharmaceutical Sciences Teikyo Heisei University Nakano Tokyo Japan Research Institute of Pharmaceutical Sciences Faculty of Pharmacy Musashino University Nishitokyo-Shi Tokyo Japan Medical Mycology Research Center Chiba University Inohana Chiba Japan

Ependymoma is a rare and chemotherapy-resistant brain tumor, which has resulted in a delay in the development of drugs to treat it. A subclass of supratentorial ependymomas (ST-EPN), designated ST-EPN-zinc finger-translocation-associated (ZFTA, ST-EPN-ZFTA), exhibits the expression of a fusion protein comprising ZFTA and v-rel reticuloendotheliosis viral oncogene homolog A (RELA), an effector transcription factor of the nuclear factor-kappa B (NF-κB) pathway (ZFTA-RELA). The expression of ZFTA-RELA results in the hyperactivation of the oncogenic NF-κB signaling pathway, which ultimately leads to the development of ST-EPN-ZFTA. To identify inhibitors of the NF-κB signaling pathway activated by the expression of ZFTA-RELA, we used a doxycycline-inducible ZFTA-RELA-expressing NF-κB reporter cell line and found that extracts of the fungus Neosartorya spinosa IFM 47025 exhibited NF-κB inhibitory activity. We identified eight compounds [aszonapyrone A (2), sartorypyrone A (3), epiheveadride (4), acetylaszonalenin (5), (R)-benzodiazepinedione (6), aszonalenin (7), sartorypyrone E (8) and (Z, Z)-N,N’-(1,2-bis[(4-methoxyphenyl)methylene]-1,2-ethanediyl)bis-formamide (9)] from N. spinosa IFM 47025 culture extract using a variety of chromatographic techniques. The structures of these compounds were identified through the analysis of various instrumental data (1D, 2D-NMR, MS, and optical rotation). The NF-κB responsive reporter assay indicated that compounds 2, 3, 5, 7, and 9 exhibited inhibitory activity. We further evaluated the inhibitory activity of these compounds against the expression of endogenous NF-κB responsive genes (CCND1, L1CAM, ICAM1, and TNF) and found that compound 2 showed significant inhibitory activity. Further studies are required to elucidate the mechanism of action of compound 2, which may serve as a lead compound for the development of a novel therapy for ST-EPN-ZFTA.

Islet transplantation is characterized by the transplantation of isolated islets from donor pancreata into a diabetic recipient. Although it is a viable choice in the treatment of insulin dependent diabetes mellitus, most patients (approximately 90%) require insulin five years after transplantation. Recently, the co-transplantation of mesenchymal stem cells (MSCs) and islets in animal studies has revealed the effectiveness of MSCs co-transplantation for improving islet function. Themechanisms underlying the beneficial impact of MSCs include immunomodulation and the promotion of angiogenesis. In this review, we discuss MSCs and how they support improved graft survival and function.

A Straight-bladed Vertical Axis Wind Turbine with a Directed Guide Vane Row-Effect of Guide Vane Geometry on the Performance-

引用

Journal of Thermal Science 2009年第1期18卷 54-57页

作者： Manabu TAKAO Hideki KUMA Takao MAEDA Yasunari KAMADA michiaki OKI Atsushi MINODA Department of Mechanical Engineering Matsue National College of Technology Department of Mechanical Engineering Mie University

The objective of this study is to show the effect of guide vane geometry on the performance. In order to overcome the disadvantages of vertical axis wind turbine, a straight-bladed vertical axis wind turbine （S-VAWT） with a directed guide vane row has been proposed and tested by the authors. According to previous studies, it was clarified that the performance of the turbine can be improved by means of the directed guide vane row. However, the guide vane geometry of S-VAWT has not been optimized so far. In order to clarify the effect of guide vanegeometry, the effects of setting angle and gap between rotor blade and guide vane on power coefticlent and start- ing characteristic were investigated in the experiments. The experimental study of the proposed wind turbine was carried out by a wind tunnel. The wind tunnel with a diameter of 1.8m is open jet type. The wind velocity is 8 m/s in the experiments. The rotor has three straight blades with a profile of NACA0018 and a chord length of 100 mm, a diameter of 0.6 m and a blade height of 0.7 m. The guide vane row consists of 3 arc plates.
