| 1 | Robust Surface Reconstruction of Plant Leaves from 3D Point Clouds显示文摘The automation of plant phenotyping using 3D imaging techniques is indispensable.However,conventional methods for reconstructing the leaf surface from 3D point clouds have a trade-off between the accuracy of leaf surface reconstruction and the method’s robustness against noise and missing points.To mitigate this trade-off,we developed a leaf surface reconstruction method that reduces the effects of noise and missing points while maintaining surface reconstruction accuracy by capturing two components of the leaf(the shape and distortion of that shape)separately using leaf-specific properties.This separation simplifies leaf surface reconstruction compared with conventional methods while increasing the robustness against noise and missing points.To evaluate the proposed method,we reconstructed the leaf surfaces from 3D point clouds of leaves acquired from two crop species(soybean and sugar beet)and compared the results with those of conventional methods.The result showed that the proposed method robustly reconstructed the leaf surfaces,despite the noise and missing points for two different leaf shapes.To evaluate the stability of the leaf surface reconstructions,we also calculated the leaf surface areas for 14 consecutive days of the target leaves.The result derived from the proposed method showed less variation of values and fewer outliers compared with the conventional methods. | Ryuhei Ando Yuko Ozasa Wei Guo | 2021 | Plant Phenomics2021，3，1： | 4 |
| 2 | Pilot-scale studies of domestic wastewater treatment by typical constructed wetlands and their greenhouse gas emissions显示文摘Three typical constructed wetlands(CWs)including Vertical Flow(VF),Free Water Surface(FWS),and Subsurface Flow(SF),and combined VF-SF-FWS constructed wetlands were investigated for the treatment of domestic wastewater with low C/N ratio.The performance of nutrient removal and the characteristics of greenhouse gas emissions,such as CH4 and N2O,from these CWs were compared.The results indicated that the four types of CWs had high removal efficiencies for organic matter and suspended solid(SS).The combined wetland also showed a comparatively good performance for nitrogen and phosphorus removal,and the removal efficiencies for total nitrogen(TN)and total phosphorus(TP)were 81.3%and 84.5%,respectively.The combined CWs had a comparative lower global warming potential.The FWS CW had the highest tendency to emit CH4 and led to a higher global warming potential among the four types of CWs,which was about 586 mg CO_(2)/m^(2)·h. | Chaoxiang LIU Kaiqin XU Ryuhei INAMORI Yoshitaka EBIE Jie LIAO Yuhei INAMORI | 2009 | Frontiers of Environmental Science & Engineering2009，3，4： | 2 |
| 3 | Do liver metastases from gastric cancer contraindicate aggressive surgical resection?A 14-year single-center experience显示文摘BACKGROUND Advanced gastric cancer(GC)with liver metastasis is often characterized by multiple and bilobular metastases and may also be associated with extrahepatic metastatic lesions.Hence,many physicians consider that radical surgeries are contraindicated for liver metastases from GC(LMGC).According to the 2017 Japanese treatment guideline for GC,a smaller number of liver metastases without unresectable factors may be an indication for liver resection(LR)with curability.The actual 5-year overall survival(OS)rate ranges from 0 to 0.37.AIM To present the institutional indications for LR for LMGC and identify important factors for prognostic outcomes.METHODS In total,30 patients underwent LR for LMGC during a 14-year period,and we evaluated the clinical,surgical,and oncological findings.In all patients,radical surgery with intentional lymphadenectomy was performed for the primary GC.The median follow-up duration after the initial LR was 33.7 mo,and three patients with no recurrence died of causes unrelated to the LMGC.The OS and recurrence-free survival rates after the initial LR were assessed.RESULTS Seventeen patients had metachronous LMGC.The initial LR achieved curability in 29 patients.Perioperative chemotherapy was introduced in 23 patients.The median greatest LMGC dimension was 30 mm,and the median number of LMGC was two.Twenty-two patients had unilobular LMGC.The 5-year OS and recurrence-free survival rates were 0.48 and 0.28,respectively.The median survival duration and recurrence-free duration after the initial LR were 16.8 and 8.6 mo,respectively.Twenty-one patients developed recurrence after the initial LR.Additional surgeries for recurrence were performed in nine patients,and these surgeries clearly prolonged the patients’survival.Pathological serosal invasion was an independent predictor of a poor prognostic outcome after the initial LR.Aggressive LR may be indicated for carefully selected patients with LMGC.CONCLUSION Our results of LR for LMGC seem acceptable.Additional surgeries for recurrence after the initial LR might prolong OS.Pathological serosal invasion is important for poor prognostic outcomes. | Takefumi Yazawa Tomohide Hori Hidekazu Yamamoto Hideki Harada Michihiro Yamamoto MasahiroYamada Masaki Tani Asahi Sato Yasuyuki Kamada Ryotaro Tani Ryuhei Aoyama Yudai Sasaki MasazumiZaima | 2020 | World Journal of Gastrointestinal Pharmacology and Therapeutics2020，11，5： | 2 |

| 5 | Distribution characteristics of ammonia-oxidizing bacteria in the Typha latifolia constructed wetlands using fluorescent in situ hybridization(FISH)显示文摘A molecular biology method, fluorescent in situ hybridization(FISH), in which the pre-treatment was improved in allusion to the media of the constructed wetlands(CW), e.g. the soil and the grit, was used to investigate the vertical distribution characteristics of ammonia-oxidizing bacteria(AOB) quantity and the relation with oxidation-reduction potential(ORP) in the Typha latifolia constructed wetlands under three different loadings in summer from May to September. Results showed that the quantity of the AOB decreased in the Typha latifolia CW with the increase of vertical depth. However, the AOB quantity was 2—4 times the quantity of the control in the root area. Additionally, ORP in the rhizosphere was found to be higher than other areas, which showed that Typha latifolia CW was in an aerobic state in summer when using simulated non-point sewage at the rural area of Taihu Lake in China and small town combined sewage. | YAN Li Ryuhei Inamori GUI Ping XU Kai-qin KONG Hai-nan Masatoshi Matsurnura Yuhei Inamori | 2005 | Journal of Environmental Sciences2005，17，6： | 1 |

| 15 | Surgical treatment of gallbladder cancer:An eight-year experience in a single center显示文摘BACKGROUND Gallbladder cancer(GBC)is the most common biliary malignancy and has the worst prognosis,but aggressive surgeries[e.g.,resection of the extrahepatic bile duct(EHBD),major hepatectomy and lymph node(LN)dissection]may improve long-term survival.GBC may be suspected preoperatively,identified intraoperatively,or discovered incidentally on histopathology.AIM To present our data together with a discussion of the therapeutic strategies for GBC.METHODS We retrospectively investigated nineteen GBC patients who underwent surgical treatment.RESULTS Nearly all symptomatic patients had poor outcomes,while suspicious or incidental GBCs at early stages showed excellent outcomes without the need for two-stage surgery.Lymph nodes around the cystic duct were reliable sentinel nodes in suspicious/incidental GBCs.Intentional LN dissection and EHBD resection prevented metastases or recurrence in early-stage GBCs but not in advanced GBCs with metastatic LNs or invasion of the nerve plexus.All patients with positive surgical margins(e.g.,the biliary cut surface)showed poor outcomes.Hepatectomies were performed in sixteen patients,nearly all of which were minor hepatectomies.Metastases were observed in the left-sided liver but not in the caudate lobe.We may need to reconsider the indications for major hepatectomy,minimizing its use except when it is required to accomplish negative bile duct margins.Only a few patients received neoadjuvant or adjuvant chemoradiation.There were significant differences in overall and disease-free survival between patients with stages≤IIB and≥IIIA disease.The median overall survival and disease-free survival were 1.66 and 0.79 years,respectively.CONCLUSION Outcomes for GBC patients remain unacceptable,and improved therapeutic strategies,including neoadjuvant chemotherapy,optimal surgery and adjuvant chemotherapy,should be considered for patients with advanced GBCs. | Yasuyuki Kamada Tomohide Hori Hidekazu Yamamoto Hideki Harada Michihiro Yamamoto MasahiroYamada Takefumi Yazawa Masaki Tani Asahi Sato Ryotaro Tani Ryuhei Aoyama Yudai Sasaki MasazumiZaima | 2020 | World Journal of Hepatology2020，12，9： | 1 |
