Terminalia mantaly H. Perrier is one of the plants of the Combretaceae family that is widely used in traditional African medicine for its antibacterial, antifungal, and especially in the treatment of malaria. In this study, we evaluated the effect of the hydroalcoholic extract of Terminalia mantaly (HAETM) on the tissue and kidney biochemical markers of rats. Forty (40) rats were randomly divided into 4 groups, assigning 10 animals within each group (5 males and 5 females per group). Animals in group 1 received distilled water and were used as the control group;on the other hand, groups 2, 3, 4 received by gavage a volume of the extract corresponding to 1 ml/100g body weight at 150 mg/kg, 300 mg/kg, 600 mg/kg, respectively. The hydroalcoholic extract was administered at the same time daily for 28 days, and blood was collected once a week to evaluate renal biochemical parameters;the kidney tissues were used to perform the histopathological study. The creatinine rate increased significantly (p Terminalia mantaly should be globally well tolerated by the body when used in doses ranging from 150 to 600 mg/kg of the body weight in animals (for this study, rats). However, further in-depth studies would be needed to get a more thorough and complete picture of the safety profile of the extract.

BACKGROUND Chemotherapy is a standard strategy for stage IV gastric cancer ***, some cases cannot undergo conversion surgery because of their frailty,even if the patients had response to chemotherapy. For these patients, local tumor progression is a problem. We report here the case of a patient whose residual gastric cancer was resected through endoscopic submucosal dissection(ESD)after concomitant chemotherapy for metastatic gastric *** SUMMARY An 85-year-old male complained of difficulty swallowing, and examination revealed gastric cancer with multiple liver metastases. Although he received concomitant chemotherapy, a residual tumor was observed in the primary lesion while the metastatic lesions disappeared completely. Conversion surgery was considered optional treatment; however, he could not undergo that because of advanced age and comorbidities. Thus, we performed ESD to treat the residual tumor. As a result, we resected the residual lesion completely. The patient has been alive for 29 mo since ESD, without *** We achieved local control using ESD, and these findings may provide therapeutic improvements both in local control and patient survival outcomes.

The APEC （Asia-Pacific Economic Cooperation） LCMT （Low-Carbon Model Town） project was initiated in 2011 as apart of APEC＇s energy cooperation scheme in response to the rapid urbanization and growing fossil energy use in the developingeconomies of the APEC region. The LCMT project has conducted feasibility studies and policy reviews for a case town eachyear and developed and refined the ＂Concept of Low-Carbon Town in the APEC region （Concept）＂. The Concept is a guidebookfor city planners and developers who wish to implement low-carbon town design. In tandem with the Concept, the ＂APECLow-Carbon Town Indicator （LCT-I） System＂ has been developed since 2013. The LCT-I System is a self-assessment tool to assessand monitor the progress of each low-carbon town development project in the APEC region. The first edition of the LCT-I SystemGuideline and its evaluation sheet were published together with the final edition of the Concept in 2016. The LCMT project ismoving into the dissemination stage beginning in 2017 through the utilization of the LCT-I System. This paper explains the processof the development of the LCT-I System, provides a brief summary and discusses its expected role in the spread of low-carbontowns.

引用

Journal of Materials Science and Chemical Engineering 2018年第7期6卷 97-103页

作者： Takuya Watanabe Hiroshi irie Special Doctoral Program for Green Energy Conversion Science and Technology Interdisciplinary Graduate School of Medicine and Engineering University of Yamanashi Yamanashi Japan Clean Energy Research Center University of Yamanashi Yamanashi Japan

Rhodium oxides, including a misfitlayered structure with alternate stacking of a rock salttype layer and a hexagonal RhO2 layer, are expected to have good thermoelectric properties. Among them, the thermoelectric properties (electrical conductivity (σ), Seebeck coefficient (S), Figure of merit (ZT) and calculated thermal conductivity (κ) by S, σ, ZT, and absolute temperature (T)) of bismuth-based rhodium oxides ((Bi1-x,Pbx) 2Sr2Rh2Oy, x = 0 and 0.02, hereafter BSR and BPSR, respectively) were investigated. In comparison with Bi2Sr2Co2Oy (BSC) at 700°C, S and κ enhanced (increased S, 110 (BSR) and 105 μV K-1 (BPSR) from 85 μV K-1 (BSC) and decreased κ, 0.32 (BSR) and 0.50 W m-1 K-1 (BPSR) from 1.75 W m-1 K-1 (BSC)), whereas σ decreased (15 (BSR) and 31 S cm-1 (BPSR) from 70 S cm-1 (BSC)). BPSR reached the highest ZT value of 0.067 at 700°C, compared to those of 0.056 (BSR) and 0.027 (BSC).

Immunohistochemical Analysis of the Acid Secretion Potency in Gastric Parietal Cells

引用

CellBio 2013年第4期2卷 179-185页

作者： Rie irie-Maezono Shinichiro Tsuyama Department of Gene Therapy and Regenerative Medicine Kagoshima University Graduate School of Medical and Dental Sciences Kagoshima Japan Laboratory for Neuroanatomy Kagoshima University Graduate School of Medical and Dental Sciences Kagoshima Japan

Gastric parietal cells are important in acid secretion, but it is unclear which cells throughout the gastric gland have the highest secretion potency. Here, we used immunohistochemical methods with anti-H+, K+-ATPase, phosphoryl ezrin and CD44 antibodies to study the distribution of gastric acid secretion activity. Stomach tissues from freely fed and starved rats were cryofixed for light microscopy or fixed by high-pressure freezing for electron microscopy. Parietal cells from freely fed animals corresponded to the active secretion phase and to the inactive resting phase from starved rats. Anti-H+, K+-ATPase and anti-phosphoryl ezrin labeling were observed on the membrane of the intracellular canaliculi and the tubulovesicle from freely fed rats, while cells from starved animals showed weak labeling with anti-phosphoryl ezrin antibody staining. Morphometrical analysis at the electron microscopic level was performed on active and inactive acid secretory phases between the upper and base regions of the gland. H+, K+-ATPase and CD44 were distributed on both sites of the microvillous and tubulovesicle membrane in the same cells, but phosphoryl ezrin localized predominantly on the microvillous membrane in active cells of the glandular neck and upper base. Therefore, the highest secreting potency appeared to be in cells of the glandular neck and upper base.

Nonequilibrium Effect in Ferromagnet-Insulator-Superconductor Tunneling Junction Currents

引用

World Journal of Condensed Matter Physics 2016年第3期6卷 169-176页

作者： Michihide Kitamura Kazuhiro Yamaki Akinobu irie Department of Electrical and Electronic System Engineering Utsunomiya University Utsunomiya Japan

Nonequilibrium effect due to the imbalance in the number of the ? and ? spin electrons has been studied for the tunneling currents in the ferromagnet-insulator-superconductor (FIS) tunneling junctions within a phenomenological manner. It has been stated how the nonequilibrium effect should be observed in the spin-polarized quasiparticle tunneling currents, and pointed out that the detectable nonequilibrium effect could be found in the FIS tunneling junction at 77 K using HgBa2Ca2Cu3O8+? (Hg-1223) high-Tc superconductor rather than Bi2Sr2CaCu2O8+? (Bi-2212) one.

Thermoelectric Properties of Silver Antimonate with Mixed Valency of Antimony

引用

Journal of Materials Science and Chemical Engineering 2017年第1期5卷 121-128页

作者： Kensuke Ozawa Hirofumi Kakemoto Hiroshi irie Interdisciplinary Graduate School of Medicine and Engineering University of Yamanashi Yamanashi Japan Clean Energy Research Center University of Yamanashi Yamanashi Japan

Silver (Ag) and silver antimonate (AgSbO3) composites with different amounts of Sb3+ were synthesized by normal sintering with the aim of realizing a thermoelectric material. The electrical conductivity (σ) increased in the sample containing larger amount of Sb3+, whereas Seebeck coefficient (S) decreased. Producing Sb3+ caused the generation of oxygen vacancies in the material, and thus the corresponding donor levels are created in the bandgap, providing more conduction electrons. The conductive Ag particles would contribute to the conduction path as bypasses for carrier transport. The thermal conductivity (κ) was slightly lower in the presence of Ag defects in AgSbO3.

Enhancement of Oxygen Evolution Activity of Ruddlesden-Popper-Type Strontium Ferrite by Stabilizing Fe4+

引用

Journal of Materials Science and Chemical Engineering 2017年第4期5卷 45-55页

作者： Toshihiro Takashima Koki Ishikawa Hiroshi irie Clean Energy Research Center University of Yamanashi Yamanashi Japan Special Doctoral Program for Green Energy Conversion Science and Technology Interdisciplinary Graduate School of Medicine and Engineering University of Yamanashi Yamanashi Japan

Development of active iron based water oxidation for designing an ideal artificial photosynthesis devices operating under benign neutral pH is highly demanded. We investigated the electrocatalytic activity of Ruddlesden-Pop-per-type strontium ferrite (Sr3Fe2O7) toward the oxygen evolution reaction (OER). Owing to the temperature-dependent efficiency of the charge disproportionation of Fe4+, the OER activity of Sr3Fe2O7 varied with the temperature, and the onset potential for the OER at a neutral pH underwent a negative shift of approximately 200 mV by increasing the temperature for the stabilization of Fe4+. When metal substitution was made to Sr3Fe2O7 for stabilizing Fe4+ at room temperature, the temperature dependence of the OER activity disappeared and the OER was driven at a small overpotential without increasing the temperature, indicating that the stabilization of Fe4+ is substantially important for achieving high OER activity.

Ohmic Hetero-Junction of n-Type Silicon and Tungsten Trioxide for Visible-Light Sensitive Photocatalyst

引用

Journal of Materials Science and Chemical Engineering 2017年第8期5卷 33-43页

作者： Masaharu Yoshimizu Yuki Hotori Hiroshi irie Special Doctoral Program for Green Energy Conversion Science and Technology Interdisciplinary Graduate School of Medicine and Engineering University of Yamanashi Yamanashi Japan Special Doctoral Program on Clean Energy Interdisciplinary Graduate School of Medicine and Engineering University of Yamanashi Yamanashi Japan Clean Energy Research Center University of Yamanashi Yamanashi Japan

Visible light-sensitive photocatalyst was developed by combining n-type silicon (n-Si) and tungsten trioxide (WO3, n-Si/WO3), yielding an ohmic contact in between. In this system, the ohmic contact acted as an electron-and-hole mediator for the transfer of electrons and holes in the conduction band (CB) of WO3 and in the valence band (VB) of n-Si, respectively. Utilizing thus- constructed n-Si/WO3, the decomposition of 2-propanolto CO2 via acetone was achieved under visible light irradiation, by the contribution of holes in the VB of WO3 to decompose 2-propanol and the consumption of electrons in the CB of n-Si to reduce O2. The combination of p-type Si (p-Si) and WO3 (p-Si/ WO3), not the ohmic contact but the rectifying contact, was much less effective, compared to n-Si/WO3.

Enhanced Visible-Light-Sensitive Two-Step Overall Water-Splitting Based on Band Structure Controls of Titanium Dioxide and Strontium Titanate

引用

Journal of Materials Science and Chemical Engineering 2017年第1期5卷 129-141页

作者： Satoshi Tanigawa Toshihiro Takashima Hiroshi irie Special Doctoral Program for Green Energy Conversion Science and Technology Interdisciplinary Graduate School of Medicine and Engineering University of Yamanashi Yamanashi Japan Clean Energy Research Center University of Yamanashi Yamanashi Japan

Visible light-induced two-step overall water-splitting was achieved by combining two types of photocatalysts, which were prepared by introducing foreign elements into rutile titanium dioxide (TiO2) and strontium titanate (SrTiO3) with a controlled electronic band structure. Rutile TiO2 and SrTiO3 were doped with chromium and tantalum (Cr,Ta-TiO2) and with rhodium (Rh-SrTiO3), respectively, to introduce visible-light sensitivity. Under irradiation with only visible light from a 420-nm LED lamp, the simultaneous liberation of hydrogen and oxygen with a molar ratio of ~2:1 was achieved with these two types of photocatalysts in the presence of iodate ion/iodide ion as a redox mediator.
