地拉那金字塔是一个新型的文化中心,位于阿尔巴尼亚首都的中心地带。地拉那金字塔最初是作为纪念共产主义者恩维尔·霍查(EnverHoxha)而建的博物馆,MVRDV对其进行了巨大的改造,现在的地拉那金字塔重新使用了混凝土结构,已经成为了一个新公园中的开放式雕塑。公园和雕塑中散布着一个个五颜六色的盒子,这些盒子散落在原来的建筑中及其周围,里面有咖啡馆、工作室、工作坊、创业办公室、孵化器、节庆活动,还有供阿尔巴尼亚青年免费学习各种技术和知识的教室。建筑倾斜的外墙还增加了台阶,让阿尔巴尼亚人民可以在这位前共产主义者的杰作上漫步。

World Journal of Gastroenterology 2008年第26期14卷 4146-4151页

作者： Cristiano Spada Maria Elena Riccioni Riccardo Urgesi guido Costamagna Digestive Endoscopy Unit Catholic UniversityRome 00168Italy

Video capsule endoscopy is an attractive and patient- friendly tool that provides high quality images of the small bowel. Obscure gastrointestinal bleeding is the primary and most evaluated indication to capsule endoscopy;however,indications are expanding and a small number of preliminary reports have been presented concerning the role of video capsule endoscopy in the diagnosis of celiac disease. The purpose of this review is to update the current knowledge and to hypothesize on future perspectives of the use of video capsule endoscopy in patients with celiac disease.

Hepatitis C-associated liver carcinogenesis:Role of PML nuclear bodies

引用

World Journal of Gastroenterology 2014年第35期20卷 12367-12371页

作者： Kerstin Herzer guido Gerken Thomas G Hofmann Department for Gastroenterology and Hepatology University Hospital Essen Department of General- Visceral- und Transplantation SurgeryUniversity Hospital Essen Cellular Senescence Group DKFZ-ZMBH AllianceDeutsches Krebsforschungszentrum (dkfz.)

Successful escape from immune response characterises chronic hepatitis C virus (HCV) infection, which results in persistence of infection in about 80% of the patients. The deleterious consequences are cirrhosis and hepatocellular carcinoma. HCV accounts the most frequent cause for hepatocellular carcinoma (HCC) and liver transplantation (LT) in the western world. The underlying molecular mechanisms how HCV promotes tumor development are largely unknown. There is some in vitro and in vivo evidence that HCV interferes with the tumor suppressor PML and may thereby importantly contribute to the HCV-associated pathogenesis with respect to the development of HCC. The tumor suppressor protein “promyelocytic leukemia” (PML) has been implicated in the regulation of important cellular processes like differentiation and apoptosis. In cancer biology, PML and its associated nuclear bodies (NBs) have initially attracted intense interest due to its role in the pathogenesis of acute promyelocytic leukemia (APL). More recently, loss of PML has been implicated in human cancers of various histologic origins. Moreover, number and intensity of PML-NBs increase in response to interferons (IFNs) and there is evidence that PML-NBs may represent preferential targets in viral infections. Thus, PML could not only play a role in the mechanisms of the antiviral action of IFNs but may also be involved in a direct oncogenic effect of the HCV on hepatocytes. This review aims to summarise current knowledge about HCV-related liver carcinogenesis and to discuss a potential role of the nuclear body protein PML for this this hard-to-treat cancer.

Comparison of fusion methods based on DST and DBN in human activity recognition

控制理论与应用（英文版） 2011年第1期9卷 18-27页

Ambient assistive living environments require sophisticated information fusion and reasoning techniques to accurately identify activities of a person under care. In this paper, we explain, compare and discuss the application of two powerful fusion methods, namely dynamic Bayesian networks (DBN) and Dempster-Shafer theory (DST), for human activity recognition. Both methods are described, the implementation of activity recognition based on these methods is explained, and model acquisition and composition are suggested. We also provide functional comparison of both methods as well as performance comparison based on the publicly available activity dataset. Our findings show that in performance and applicability, both DST and DBN are very similar; however, significant differences exist in the ways the models are obtained. DST being top-down and knowledge-based, differs significantly in qualitative terms, when compared with DBN, which is data-driven. These qualitative differences between DST and DBN should therefore dictate the selection of the appropriate model to use, given a particular activity recognition application.

Unravel hepatic artery infusion chemotherapy in patients with resected colorectal liver metastases

Hepatobiliary Surgery and Nutrition 2021年第2期10卷 257-260页

作者： Matteo Donadon Lorenza Rimassa guido Torzilli Department of Biomedical Sciences Humanitas UniversityPieve EmanueleMilanItaly Department of Hepatobiliary and General Surgery IRCCS Humanitas Research HospitalRozzanoMilanItaly Humanitas Cancer Center IRCCS Humanitas Research HospitalRozzanoMilanItaly

Over the past years,important progresses have been made in the treatment of patients with colorectal liver metastases(CLM).Now,5-year overall survival rate may exceed 50%by using the combination of multimodality therapies among which modern systemic chemotherapy,with or without monoclonal antibodies,and hepatic resection are the cornerstones(1,2).In such multimodality,hepatic artery infusion(HAI)has been proposed since many years with the rationale of increasing the concentration of chemotherapy agents in the liver(3).However,HAI still remains infrequently used,in particular in the adjuvant setting mainly because of the requirement of a multidisciplinary team to manage therapy,and the more widespread use of systemic chemotherapy-in particular following the perioperative“sandwich”schema(4).
