| 4 | 亲水作用色谱柱与阳离子交换树脂柱结合分离无机离子(英文)显示文摘A combination of hydrophilic interaction chromatographic(HILIC) column and a weakly acidic cation-exchange resin(WCX) column was used for simultaneous separation of inorganic anions and cations by ion chromatography(IC).Firstly,the capability of HILIC column for the separation of analyte ions was evaluated under acidic eluent conditions.The columns used were SeQuant ZIC-HILIC(ZIC-HILIC) with a sulfobetaine-zwitterion stationary phase(ZIC-HILIC) and Acclaim HILIC-10 with a diol stationary phase(HILIC-10).When using tartaric acid as the eluent,the HILIC columns indicated strong retentions for anions,based on ion-pair interaction.Especially,HILIC-10 could strongly retain anions compared with ZIC-HILIC.The selectivity for analyte anions of HILIC-10 with 5 mmol/L tartaric acid eluent was in the order of I-> NO-3 > Br-> Cl-> H2PO-4.However,since HILIC-10 could not separate analyte cations,a WCX column(TSKgel Super IC-A/C) was connected after the HILIC column in series.The combination column system of HILIC and WCX columns could successfully separate ten ions(Na+,NH+4,K+,Mg2+,Ca2+,H2PO-4,Cl-,Br-,NO-3 and I-) with elution of 4 mmol/L tartaric acid plus 8 mmol/L 18-crown-6.The relative standard deviations(RSDs) of analyte ions by the system were in the ranges of 0.02%-0.05% in retention times and 0.18%-5.3% in peak areas through three-time successive injections.The limits of detection at signal-to-noise ratio of 3 were 0.24-0.30 μmol/L for the cations and 0.31-1.2 μmol/L for the anions.This system was applied for the simultaneous determination of the cations and the anions in a vegetable juice sample with satisfactory results. | Kaori ARAI Masanobu MORI Takahiro HIRONAGA Hideyuki ITABASHI Kazuhiko TANAKA | 2012 | 色谱2012，30，4： | 1 |

| 6 | Relationship between biological factors and catastrophizing and clinical outcomes for female patients with knee osteoarthritis显示文摘AIM To investigate the correlations between clinical outcomes and biopsychological variables in female patients with knee osteoarthritis(OA).METHODS Seventy-seven patients with symptomatic knee OA were enrolled in this study.We investigated the age,body mass index(BMI),pain catastrophizing scale(PCS)and radiographic severity of bilateral knees using a Kellgren-Lawrence(K-L)grading system of the subjects.Subsequently,a multiple linear regression was conducted to determine which variables best correlated with main outcomes of knee OA,which were pain severity,moving capacity by measuring timed-up-and-go test and Japanese Knee Osteoarthritis Measure(JKOM).RESULTS We found that the significant contributor to pain severity was PCS(β=0.555)and BMI(β=0.239),to moving capacity was K-L grade(β=0.520)and to PCS(β=0.313),and to a JKOM score was PCS(β=0.485)and K-L grade(β=0.421),respectively.CONCLUSION The results suggest that pain catastrophizing as well as biological factors were associated with clinical outcomes in female patients with knee OA,irrespective of radiographic severity. | Tatsunori Ikemoto Hirofumi Miyagawa Yukiko Shiro Young-Chang Park Arai Machiko Akao Kenta Murotani Takahiro Ushida Masataka Deie | 2017 | World Journal of Orthopedics2017，8，3： | 1 |

| 9 | Eosinophilic enteritis requiring differentiation from chronic enteropathy associated with SLCO2A1 gene:A case report显示文摘BACKGROUND Eosinophilic gastrointestinal disease(EGID)is a disorder characterized by infiltration of eosinophils causing mucosal damage and dysfunction of the gastrointestinal tract.The endoscopic findings of eosinophilic enteritis(EoN),an EGID variant,are nonspecific and occasionally difficult to diagnose.In contrast,chronic enteropathy associated with SLCO2A1(CEAS)is a chronic persistent small intestinal disorder characterized by endoscopic findings such as multiple oblique and circular ulcers.CASE SUMMARY We report the case of a 10-year-old boy who had suffered abdominal pain and fatigue for the preceding 6 mo.He was referred to our institute for investigation of suspected gastrointestinal bleeding because of severe anemia with hypoproteinemia and positive fecal human hemoglobin.The upper and lower gastrointestinal endoscopic findings were normal;however,double-balloon small bowel endoscopy showed multiple oblique and circular ulcers with discrete margins and mild constriction of the intestinal lumen in the ileum.The findings were highly consistent with CEAS,but urine prostaglandin metabolites were within normal limits,and no previously reported mutations in the SLCO2A1 gene were identified.Histological evaluation demonstrated moderate to severe eosinophilic infiltration localized to the small intestine suggesting a diagnosis of EoN.Clinical remission was maintained with montelukast and a partial elemental diet,but emergent surgery for bowel obstruction due to small intestinal stenosis was performed two years after the initial treatment.CONCLUSION EoN should be considered in the differential diagnosis of CEAS-like small intestinal ulcerative lesions and normal urinary prostaglandin metabolite levels. | Kantaro Kimura Keisuke Jimbo Nobuyasu Arai Masamichi Sato Mitsuyoshi Suzuki Takahiro Kudo Tomonori Yano Toshiaki Shimizu | 2023 | World Journal of Gastroenterology2023，29，11： | 0 |
| 10 | Numerical model of local scour considering the unsteady sediment inflow and sediment sorting: Application to scour upstream of slit weir显示文摘The current study proposes a novel framework for the numerical model for estimating the temporal scour considering unsteady sediment inflow and the sediment sorting process. The framework was applied to local scour upstream of a slit weir. The scour model is based on an ordinary nonlinear differential equation derived from sediment continuity and scour rate equations. A one-dimensional(1-D)Boussinesq-type model coupled with nonequilibrium sediment transport was incorporated in the scour model to consider unsteady sediment inflow. In addition, a mixing layer approach was incorporated to determine temporal variations in particle size in the scour hole. The proposed framework was validated using scour experiments conducted under conditions that include non-uniform sediment, live-bed scour,and unsteady flow rate. The simulation results showed satisfactory agreement with experimental results for the scour upstream of a slit weir. The proposed model appropriately explained the hysteresis process for flow unsteadiness, refilling process for live-bed scour, and armoring process for non-uniform sediments. In addition, the model framework proposed in the current study is applicable to local scour around other hydraulic structures(e.g., bridge piers) upon establishing the scour rate equation. Therefore, the current study provides a novel approach for modeling temporal scour that is required to consider unsteady sediment inflow and sediment sorting. | Kazuyuki Ota Takahiro Sato Ryosuke Arai | 2022 | International Journal of Sediment Research2022，37，4： | 0 |
| 11 | Experimental investigation on cohesionless sandy bank failure resulting from water level rising显示文摘In the last decade, sediment replenishment forming cohesionless sandy banks below dams has become an increasingly common practice in Japan to compensate for sediment deficits downstream. The erosion process of the placed cohesionless sediment is a combination of lateral toe-erosion and the following mass failure. To explore cohesionless bank failure mechanisms, a series of experiments was done in a soil tank using a compacted sandy soil mass exposed to an increasing water level. Two types of uniform sand(D_(50) = 0.40 mm and 0.17 mm) and two bank heights(50 cm and 25 cm) were used under the condition of a constant bank slope of 75°. The three dimensional(3D) geometry of the bank after failure was measured using a handheld 3D scanner. The motion of bank failure was captured using the particle image velocimetry(PIV) technique, and the matric suction was measured by tensiometers. The compacted sandy soil was eroded by loss of matric suction accompanying the rise in water level which subsequently caused rotational slide and cantilever toppling failure due to destabilization of the bank. The effect of erosion protection resulting from the slumped blocks after these failures is discussed in the light of different failure mechanisms. Tensile strength is analyzed by inverse calculation of cantilever toppling failure events. The tensile strength had non-linear relation with degree of saturation and showed a peak.The findings of the study show that it is important to incorporate the non-linear relation of tensile strength into stability analysis of cantilever toppling failure and prediction of tension crack depth within unsaturated cohesionless banks. | Ryosuke Arai Kazuyuki Ota Takahiro Sato Yasushi Toyoda | 2018 | International Journal of Sediment Research2018，33，1： | 0 |
