    <p>In this study, the electrical conductivity of a small sample of simulated plasma was measured by a microfluidic chip with electrodes. Saline samples of different concentrations were evaluated based on saline (0.9 w/v% NaCl solution). The electrical conductivity of samples of saline with albumin was also measured. In order to investigate whether the differences in conductivity were due to viscosity following Walden’s law, we correlated the electrical conductivity with the viscosity evaluated by the capillary method.</p>

We were able to show the difference of electrical conductivity in the samples of saline solution (0.9w/v% NaCl solution) with sucrose. The correlation between the electrical conductivity and the viscosity evaluated by the capillary method was shown. This correlation was shown that it is possible to evaluate viscosity based on the Walden's rule with our chip.</p>

    <p>To protect a satellite from accidents due to spacecraft charging, Kyushu Institute of Technology (Kyutech) is developing a device called ELFs-Charm, which stands for ELectron-emitting Film for Spacecraft CHARging Mitigation. Electron emission from ELFs-Charm was already confirmed in Polar Earth Orbit in 2012 via flight experiment onboard HORYU-II. As a next step, we are considering the practical operation for spacecraft charging mitigation. The present emission level is not enough to increase the satellite potential. We focus our efforts on improving two properties, charging property and the emission threshold. The charging property is measured by how well the differential voltage between the ELFs-charm insulator surface and the satellite chassis increases. The emission threshold is measured by the differential voltage when the electron emission starts. This paper reports the laboratory experimental results to measure the two properties of various samples. The sample made of fluorin resin coating had a good combination of the charging property and the emission threshold that makes it possible to emit electron under realistic ambient electron current density in orbit.</p>

    <p>A silicon X-ray sensor with trench-structured photodiodes was studied and the influence of Compton scattering was estimated. By irradiating the target pixel with X-rays and measuring the signal from adjacent pixels, X-ray scattering and pixel blur of the proposed sensor was determined. An X-ray sensor with a length of 22.6 mm was designed and fabricated, and its modulation transfer function (MTF) was obtained. A sensor structure to improve the MTF level to that of CdTe was proposed.</p>

    医療費増加の大きな原因となっている生活習慣病の予防のためには、そのリスク要因である食後高脂血症や糖尿病を判定する必要がある。糖尿病患者や脂質異常症患者と健常者において血液粘度を比較すると、前者の血液粘度が高い値を示すことが報告されている。そのため、家庭などで簡便に数μL量の血液を用いて血液粘度を評価できれば、生活習慣病の予防や、糖尿病や脂質異常症の患者のセルフメディケーションに大きな貢献をすると考えられている。
    本研究では、簡易血液粘度測定装置を開発し、患者のセルフメディケーションを支援する。本研究期間では簡易血液粘度測定装置のために、①血液1滴(1μL程度)で全血および血漿の粘度測定を可能にするマイクロ流体チップの研究、②マイクロ流体チップ上で全血成分から血漿成分を測定するための血球分離機構の研究、③マイクロ流体チップの大量生産化研究の3つに関して取り組む。

  • 急性胆嚢炎患者の胆汁性状(粘 度)測定と、PTGBA・PTGBD の 適応に関する検討

    2023.06 - 2024.03

     More details

    Grant type:Joint research

    急性胆管炎・胆嚢炎診療ガイドライン2018(TG18)では、手術リスクの高い中等症もしくは重症の胆嚢炎患者に対して胆嚢ドレナージを推奨している。胆嚢ドレナージの手段としては、経皮経肝胆嚢ドレナージ(PTGBD)、経皮経肝胆嚢穿刺吸引法(PTGBA)、内視鏡的経乳頭的胆嚢ドレナージ(ETGBD)、超音波内視鏡下胆嚢ドレナージ(EUS-GBD)が挙げられる。ETGBD やEUS-GBD は胆膵内視鏡エキスパートが必要な手技とされ、標準ドレナージ法とまではまだ言えず、そのような体制でない施設ではPTGBD・PTGBA を考慮する。
    PTGBD・PTGBA ともに有用性のある手技とされるが、TG18 においてPTGBA は濃縮胆汁や膿性胆汁ではドレナージが十分ではないとされている(穿刺針の太さに関係)。ただ、そのような胆汁性状を穿刺前に判断する基準は明記されていない。そこで、CT 検査や超音波検査所見等から胆汁性状(粘度)を測定し、その性状によってPTGBA とPTGBD の適応が判断できるのかを段階を経て検討する。
