| 1 | The woodchuck as an animal model for pathogenesis and therapy of chronic hepatitis B virus infection显示文摘This review describes the woodchuck and the woodchuck hepatitis virus (WHV) as an animal model for pathogenesis and therapy of chronic hepatitis B virus (HBV) infection and disease in humans. The establishment of woodchuck breeding colonies, and use of laboratory-reared woodchucks infected with defined WHV inocula, have enhanced our understanding of the virology and immunology of HBV infection and disease pathogenesis, including major sequelae like chronic hepatitis and hepatocellular carcinoma. The role of persistent WHV infection and of viral load on the natural history of infection and disease progression has been firmly established along the way. More recently, the model has shed new light on the role of host immune responses in these natural processes, and on how the immune system of the chronic carrier can be manipulated therapeutically to reduce or delay serious disease sequelae through induction of the recovery phenotype. The woodchuck is an outbred species and is not well defined immunologically due to a limitation of available host markers. However, the recent development of several key host response assays for woodchucks provides experimental opportunities for further mechanistic studies of outcome predictors in neonatal- and adult-acquired infections. Understanding the virological and immunological mechanisms responsible for resolution of self-limited infection, andfor the onset and maintenance of chronic infection, will greatly facilitate the development of successful strategies for the therapeutic eradication of established chronic HBV infection. Likewise, the results of drug efficacy and toxicity studies in the chronic carrier woodchucks are predictive for responses of patients chronically infected with HBV. Therefore, chronic WHV carrier woodchucks provide a well-characterized mammalian model for preclinical evaluation of the safety and efficacy of drug candidates, experimental therapeutic vaccines, and immunomodulators for the treatment and prevention of HBV disease sequelae. | Stephan Menne Paul J Cote | 2007 | World Journal of Gastroenterology2007,13,1: | 22 |
| 2 | Metastatic type 1 gastric carcinoid:A real threat or just a myth?显示文摘AIM:To describe disease characteristics and treatment modalities in a group of rare patients with metastatic gastric carcinoid type 1(GCA1).METHODS:Information on clinical,biochemical,radiological,histopathological findings,the extent of the disease,as well as the use of different therapeutic modalities and the long-term outcome were recorded.Patients’data were assessed at presentation,and thereafter at 6 to 12 monthly intervals both clinically and biochemically,but also endoscopically and histopathologically.Patients were evaluated for the presence of specific symptoms;the presence of autoimmune disorders and the presence of other gastrointestinal malignancies in other family members were also recorded.The evaluation of response to treatment was defined using established WHO criteria.RESULTS:We studied twenty consecutive patients with a mean age of 55.1 years.The mean follow-up period was 83 mo.Twelve patients had regional lymph node metastases and 8 patients had liver metastases.The primary tumor mean diameter was 20.13±10.83mm(mean±SD).The mean Ki-67 index was 6.8%±11.2%.All but one patient underwent endoscopic or surgical excision of the tumor.The disease was stable in all but 3 patients who had progressive liver disease.All patients remained alive during the follow-up period.CONCLUSION:Metastatic GCA1 carries a good overall prognosis,being related to a tumor size of≥1 cm,an elevated Ki-67 index and high serum gastrin levels. | Simona Grozinsky-Glasberg Dimitrios Thomas Jonathan R Strosberg Ulrich-Frank Pape Stephan Felder Apostolos V Tsolakis Krystallenia I Alexandraki Merav Fraenkel Leonard Saiegh Petachia Reissman Gregory Kaltsas David J Gross | 2013 | World Journal of Gastroenterology2013,19,46: | 11 |
| 3 | The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment. | ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart | 2019 | Science China(Physics,Mechanics & Astronomy)2019,62,2: | 11 |
| 4 | 两种新型骨水泥的组织学和生物力学研究显示文摘我们研制了两种可被骨长入的骨水泥:一种是部分可吸收的骨水泥(PRC),以双酚α-甲基丙烯酸甘油酯(Bis-GMA)为基质,混合硅铝陶瓷和可吸收性聚合体颗粒调制成;另一种是磷酸钙骨水泥(CPC),由磷酸三钙、一水磷酸二氢钙、二水磷酸二钙和黄原胶组成。将这两种骨水泥分别植入家兔股骨和胫骨髁的骨缺损中,植入后2、4、12和24周取材,进行组织学观察和生物力学测试。结果发现,CPC组有递增的骨整合,伴有生物降解及巨噬细胞出现,力学测试显示抗压强度在4周之前一直降低,4周后才轻微升高,弹性模量随时间普遍降低。到第4周时,组织学观察还发现新生骨与CPC边缘直接接触。整个观察过程中未发现炎症反应。PRC组,骨整合及生物降解都很轻微,但在各个观察阶段,其抗压强度比松质骨和CPC组高(p<0.05),在4周之前,它的弹性模量高于松质骨和CPC组,4周后低于松质骨。(Bone 25:41S--45S;1999)。 | 卢建熙 I ABOUT G STEPHAN P VAN LANDUYT J DEJOU M FIOCCHI J LEMAITRE J-P PROUST | 2000 | 医用生物力学2000,15,3: | 10 |

| 7 | Trans-arterial chemoperfusion for the treatment of liver metastases of breast cancer and colorectal cancer: Clinical results in palliative care patients显示文摘AIM To evaluate the clinical value and efficiency of transarterial chemoperfusion(TACP) in patients with liver metastases from breast cancer(BC) and colorectal cancer(CRC).METHODS We treated 36 patients with liver metastases of BC(n = 19, 19 females) and CRC(n = 17; 8 females, 9 males) with repeated TACP. The treatment interval was 4 wk. TACP was performed with gemcitabine(1000 mg/m2) and mitomycin(10 mg/m2), administered within 1 h after positioning the catheter tip in the hepatic artery. Before treatment, the size, location, tumour volume, vascularization and number of liver tumours were evaluated using magnetic resonance imaging(MRI). Tumour response was evaluated according to the Response Evaluation Criteria in Solid Tumors guidelines.RESULTS TACP using gemcitabine and mitomycin for metastases from CRC and BC was performed without any serious side effects. The follow-up MRI showed a therapeutic response in 84.2% of the BC patients-stable disease 47.4% and partial response 36.8%. A progression was seen in 15.8%.CRC patients showed a therapeutic response in 52.9% of cases. A progression of the disease was documented in 47.1% of the patients with CRC. These data show that TACP in patients with liver metastases of BC leads to a significantly better therapeutic response compared with CRC patients(P = 0.042). The median survival time was 13.2 mo for the BC patients, which is significantly longer than for CRC patients at 9.3 mo(P = 0.001).CONCLUSION TACP for liver metastases of BC appears to be a safe and effective palliative treatment with improved outcomes in comparison to patients with CRC. | Tatjana Gruber-Rouh Marcel Langenbach Nagy NN Naguib Nour-Eldin M Nour-Eldin Thomas J Vogl Stephan Zangos Martin Beeres | 2017 | World Journal of Clinical Oncology2017,8,4: | 7 |

| 9 | Retrospective analysis of old-age colitis in the Dutch inflammatory bowel disease population显示文摘AIM: To describe the characteristics of Dutch patients with chronic inflammatory bowel disease (IBD) first diagnosed above 60 years of age-a disease also known as old-age colitis (OAC) and to highlight a condition that has a similar appearance to IBD, namely segmen- tal colitis associated with diverticular disease (SCAD). METHODS: A retrospective longitudinal survey of patient demographic and clinical characteristics, disease characteristics, diagnostic methods, management and course of disease was performed. The median follow-up period was 10 years. RESULTS: Of a total of 1100 IBD patients attending the Department of Gastroenterology, 59 (5%) [median age 82 years (range 64-101); 25 male (42%)] were identified. These patients were diagnosed with ulcerative colitis (n = 37, 61%), Crohn’s disease (n = 14, 24%), and indeterminate colitis (n = 8, 15%). Remission was induced in 40 (68%) patients within a median interval of 6 mo (range 1-21) and immunosuppressive therapy was well tolerated. Histological evaluation based on many biopsy samples and the course of the disease led to other diagnosis, namely SCAD instead of IBD in five (8%) patients. CONCLUSION: OAC is not an infrequent problem for the gastroenterologist, and should be considered in the evaluation of older patients with clinical featuressuggestive of IBD. Extra awareness and extensive biopsy sampling are required in order to avoid an erroneous diagnosis purely based on histological mimicry of changes seen in SCAD, when diagnosing IBD in the presence of diverticulosis coli. | Muhammed Hadithi Marcel Cazemier Gerrit A Meijer Elisabeth Bloemena Richel J Felt-Bersma Chris J Mulder Stephan GM Meuwissen Amado Salvador Pea Adriaan A van Bodegraven | 2008 | World Journal of Gastroenterology2008,14,20: | 3 |

| 11 | Antimicrobial peptides and the gut microbiome in inflammatory bowel disease显示文摘Antimicrobial peptides(AMP)are highly diverse and dynamic molecules that are expressed by specific intestinal epithelial cells,Paneth cells,as well as immune cells in the gastrointestinal(GI)tract.They play critical roles in maintaining tolerance to gut microbiota and protecting against enteric infections.Given that disruptions in tolerance to commensal microbiota and loss of barrier function play major roles in the pathogenesis of inflammatory bowel disease(IBD)and converge on the function of AMP,the significance of AMP as potential biomarkers and novel therapeutic targets in IBD have been increasingly recognized in recent years.In this frontier article,we discuss the function and mechanisms of AMP in the GI tract,examine the interaction of AMP with the gut microbiome,explore the role of AMP in the pathogenesis of IBD,and review translational applications of AMP in patients with IBD. | John Gubatan Derek R Holman Christopher J Puntasecca Danielle Polevoi Samuel JS Rubin Stephan Rogalla | 2021 | World Journal of Gastroenterology2021,27,43: | 3 |

| 14 | Short-Term Response of Soil Respiration to Addition of Chars:Impact of Fermentation Post-Processing and Mineral Nitrogen显示文摘The biodegradability of chars derived from pyrolysis and hydrothermal carbonisation(HTC) was studied in short-term dynamic incubation experiments under controlled conditions. Carbon dioxide C(CO2) emissions from soil-char mixtures in combination with solid digestate or mineral nitrogen(N) fertiliser were measured in dynamic chambers for 10 d. Compared to the original material(maize straw), pyrolysis and HTC chars showed significantly lower CO2 emissions and slower decay dynamics; and compared to the soil control, HTC char increased soil respiration to a significant extent, while pyrolysis char did not. The addition of mineral N resulted in a delayed respiration dynamics for HTC char, while the addition of digestate resulted in an increase in the respired CO2 for pyrolysis char and a decrease for HTC char. For the first time, a peculiar two-stage decay kinetics was observed for HTC char,indicating a highly inhomogeneous substrate consisting at least of two C pools. | Giacomo LANZA Stephan WIRTH Arthur GESSLER Jrgen KERN | 2015 | Pedosphere2015,25,5: | 2 |
