| 1 | Ultralow-loss geometric phase and polarization shaping by ultrafast laser writing in silica glass显示文摘Polarization and geometric phase shaping via a space-variant anisotropy has attracted considerable interest for fabrication of flat optical elements and generation of vector beams with applications in various areas of science and technology.Among the methods for anisotropy patterning,imprinting of self-assembled nanograting structures in silica glass by femtosecond laser writing is promising for the fabrication of space-variant birefringent optics with high thermal and chemical durability and high optical damage threshold.However,a drawback is the optical loss due to the light scattering by nanograting structures,which has limited the application.Here,we report a new type of ultrafast laser-induced modification in silica glass,which consists of randomly distributed nanopores elongated in the direction perpendicular to the polarization,providing controllable birefringent structures with transmittance as high as 99% in the visible and near-infrared ranges and >90% in the UV range down to 330 nm.The observed anisotropic nanoporous silica structures are fundamentally different from the femtosecond laser-induced nanogratings and conventional nanoporous silica.A mechanism of nanocavitation via interstitial oxygen generation mediated by multiphoton and avanlanche defect ionization is proposed.We demonstrate ultralow-loss geometrical phase optical elements,including geometrical phase prism and lens,and a vector beam convertor in silica glass. | Masaaki Sakakura Yuhao Lei Lei Wang Yan-Hao Yu Peter G.Kazansky | 2020 | Light(Science & Applications)2020,9,1: | 14 |
| 2 | Optimal duration of the early and late recurrence of hepatocellular carcinoma after hepatectomy显示文摘AIM: To determine the best cut-off value between the early and late recurrence periods after the initial recurrence of hepatocellular carcinoma(HCC).METHODS: The clinical records of 404 patients who underwent macroscopic curative hepatectomy for HCC between 1980 and 2010 were retrospectively examined. We divided the 252 patients experienced a recurrence of HCC into two groups, the early and late recurrence groups using the 'minimum P-value' approach. Factors for early recurrence were investigated using all 404 patients, and factors related to late recurrence were investigated in the patients who were confirmed to be recurrence free at the end of the early recurrence period.RESULTS: For the 252 patients who experienced a recurrence, the optimal cut-off value for differentiating early and late recurrence based on the overall survival after initial recurrence was 17 mo(5-year overall survival after initial recurrence: 15.4% vs 36.3%, P = 0.000018). Cox proportional hazard analysis identified early recurrence(P = 0.003) as one of the independent prognostic factors associated with overall survival after initial recurrence. A logistic regression model showed that an alpha-fetoprotein level > 100 ng/m L(P < 0.001), multiple HCC(P < 0.001), serosal invasion(P = 0.031), and microvascular invasion(P = 0.012) were independent factors associated with early recurrence, whereas the only independent factor related to late recurrence was liver cirrhosis(P = 0.002).CONCLUSION: Seventeen months after hepatectomy is a useful cut-off value between early and late recurrence of HCC based on the prognosis and different etiologies. | Yusuke Yamamoto Hisashi Ikoma Ryo Morimura Hirotaka Konishi Yasutoshi Murayama Shuhei Komatsu Atsushi Shiozaki Yoshiaki Kuriu Takeshi Kubota Masayoshi Nakanishi Daisuke Ichikawa Hitoshi Fujiwara Kazuma Okamoto Chouhei Sakakura Toshiya Ochiai Eigo Otsuji | 2015 | World Journal of Gastroenterology2015,21,4: | 14 |
| 3 | Surgical treatment of hepatocellular carcinoma with severe intratumoral arterioportal shunt显示文摘We report a case of hepatocellular carcinoma (HCC) that caused a severe arterioportal shunt (APS). A 49-year-old man was admitted to hospital due to esophagogastric variceal hemorrhage and HCC, and underwent endoscopic variceal ligation (EVL) and endoscopic injection sclerotherapy (EIS). He was then referred to our hospital. Abdominal computed tomography revealed a lowdensity lesion in the posterior segment of the liver and an intratumoral APS, which caused portal hypertension. Although the patient underwent EVL, EIS, Hassab’s operation, and transcatheter arterial embolization for APS, he vomited blood due to rupture of esophagogastric varices. Right hepatectomy was performed for the treatment of HCC and APS, although the indocyanine green retention value at 15 min after intravenous injection was poor (30%). The patient’s postoperative course was uneventful. Eventually, APS disappeared and the esophagogastric varices improved. | Hiromichi Ishii Teruhisa Sonoyama Shingo Nakashima Hiroyuki Nagata Atsushi Shiozaki Yoshiaki Kuriu Hisashi Ikoma Masayoshi Nakanishi Daisuke Ichikawa Hitoshi Fujiwara Kazuma Okamoto Toshiya Ochiai Yukihito Kokuba Chohei Sakakura Eigo Otsuji | 2010 | World Journal of Gastroenterology2010,16,25: | 11 |
| 4 | Post-hepatectomy survival in advanced hepatocellular carcinoma with portal vein tumor thrombosis显示文摘AIM: To analyze hepatocellular carcinoma(HCC) patients with portal vein tumor thrombosis(PVTT) using the tumor-node-metastasis(TNM) staging system.METHODS: We retrospectively analyzed 372 patients with HCC who underwent hepatectomy between 1980 and 2009.We studied the outcomes of HCC patients with PVTT to evaluate the American Joint Committee on Cancer TNM staging system(7th edition) for stratifying and predicting the prognosis of a large cohort of HCC patients after hepatectomy in a single-center.Portal vein invasion(vp) 1 was defined as an invasion or tumor thrombus distal to the second branch of the portal vein,vp2 as an invasion or tumor thrombus in the second branch of the portal vein,vp3 as an invasion or tumor thrombus in the first branch of the portal vein,and vp4 as an invasion or tumor thrombus in the portal trunk or extending to a branch on the contralateral side.RESULTS: The cumulative 5-year overall survival(5yr OS) and 5-year disease-free survival(5yr DFS) rates of the 372 patients were 58.3% and 31.3%,respectively.The 5yr DFS and 5yr OS of vp3-4 patients(n = 10) were 20.0%,and 30.0%,respectively,which was comparable with the corresponding survival rates of vp1-2 patients(P = 0.466 and 0.586,respectively).In the subgroup analysis of patients with macroscopic PVTT(vp2-4),the OS of the patients who underwent preoperative transarterial chemoembolization was comparable to that of patients who did not(P = 0.747).There was a significant difference in the DFS between patients with stage Ⅰ HCC and those with stage Ⅱ HCC(5yr DFS 39.2% vs 23.1%,P < 0.001); however,theDFS for stage Ⅱ was similar to that for stage Ⅲ(5yrD FS 23.1% vs 13.8%,P = 0.330).In the subgroup analysis of stage Ⅱ-Ⅲ HCC(n = 148),only alpha-fetoprotein(AFP) > 100 mg/dL was independently associated with DFS.CONCLUSION: Hepatectomy for vp3-4 HCC results in a survival rate similar to hepatectomy for vp1-2.AFP stratified the stage Ⅱ-Ⅲ HCC patients according to prognosis. | Yusuke Yamamoto Hisashi Ikoma Ryo Morimura Katsutoshi Shoda Hirotaka Konishi Yasutoshi Murayama Shuhei Komatsu Atsushi Shiozaki Yoshiaki Kuriu Takeshi Kubota Masayoshi Nakanishi Daisuke Ichikawa Hitoshi Fujiwara Kazuma Okamoto Chouhei Sakakura Toshiya Ochiai Eigo Otsuji | 2015 | World Journal of Gastroenterology2015,21,1: | 9 |

| 6 | Recurrent chromosomal rearrangements at bands 8q24 and 11q13 in gastric cancer as detected by multicolor spectral karyotyping显示文摘AIM: To identify chromosomal translocations specific to gastric cancer (GC), spectral karyotyping (SKY) analysis was performed on established cell lines and cancerous ascitic fluids.METHODS: SKY analysis of 10 established cell lines and seven cancerous ascitic fluid samples identified recurrent chromosomal breakpoints and translocations in GC,several of which involved chromosomal loci of oncogenes or tumor suppressor genes.RESULTS: A total of 630 chromosomal breaks were identified. Chromosome no.8 was the most frequently involved in rearrangements (65 breaks), followed by chromosomes no. 11 (53), no. 1 (49), no. 7 (46), no. 13 (37), no. 3 (36), no. 17 (33), and no. 20 (29). Frequent breakpoints were detected in 8q24.1 (30 breaks), 11q13 (29), 13q14 (16), 20q11.2 (14), 7q32 (13), 17q11.2 (13),18q21 (12), 17q23 (9), 18q11.2 (9). SKY analysis identified a total of 242 chromosomal rearrangements including 190 reciprocal and non-reciprocal translocations. The recurrent combinations of chromosomal bands involved in translocations were 8q24.1 and 13q14 (3 cases), 8q24.1 and 11q13 (3), 11q13 and 17q11.2 (2), and 18q11.2 and 20q11.2 (2). Our study validated the ability of SKY to characterize in detail the chromosomal rearrangements in solid tumors and derived cell lines. Moreover,fluorescence in situ hybridization helped to identify the insertions, translocations, and homogeneously staining regions of MYCand CCND1 gene loci.CONCLUSION: The non-random co-localization of certain cytogenetic bands suggests the importance of chromosomal translocations in gastric carcinogenesis, by serving as landmarks for the cloning of GC causing genes. | Yasuhide Yamashita Kazuhiro Nishida Takashi Okuda Kenichi Nomura Yosuke Matsumoto Shoji Mitsufuji Shigeo Horiike Hiroyuki Hata Chohei Sakakura Akio Hagiwara Hisakazu Yamagishi Masafumi Taniwaki | 2005 | World Journal of Gastroenterology2005,11,33: | 4 |
| 7 | Picosecond burst pulse machining with temporal energy modulation [Invited]显示文摘Suppression of stress and crack generation during picosecond laser processing in transparent brittle materials such as glass was successfully demonstrated by a picosecond laser pulse with temporal energy modulation.The origin of deterioration in processing accuracy could be interpreted in terms of the discontinuous movement of plasma in the vicinity of the focus.To reveal the effectiveness of the temporal energy modulation for smootli machining,such plasma motion was simulated by the fiidtc-d ifference time-domain method.F urt her more,photoinduced birefringence was observed using a high-speed polarization camera. | Akinao Nakamura Tomoki Mizuta Yasuhiko Shimotsuma Masaaki Sakakura Tomohito Otobe Masahiro Shimizu Kiyotaka Miura | 2020 | Chinese Optics Letters2020,18,12: | 2 |
