| 1 | Malignant carcinoid tumor of the cystic duct:a rare cause of bile duct obstruction显示文摘BACKGROUND:Carcinoid tumors of the extrahepatic biliary tree are extremely rare malignancies,accounting for 0.2%-2%of all gastrointestinal carcinoid tumors,while carcinoids of the cystic duct are an uncommon entity and an extremely unusual cause of bile duct obstruction.METHODS:After an extensive literature review,we retrospectively analysed 61 cases of carcinoid tumor of the biliary tree as well as one additional case of a 60-yearold female with symptoms and laboratory/imaging examination findings compatible with those of a malignant biliary tract obstruction.At laparotomy,resection of the gallbladder and common bile duct was performed.Histological study revealed a well-differentiated neuroendocrine carcinoma of the cystic duct.The patient remained disease-free at 16 months.RESULTS:Our presentation is the seventh case reported in the world literature.Compared to cholangiocarcinoma,analysis of the reviewed group indicates an increased incidence of extrahepatic carcinoid tumors in younger persons along with a slight female predominance.Statistically,the most common anatomic location is the common bile duct,followed by the perihilar region and the cystic duct.Jaundice is the most common finding.Curative surgery was realized in the majority of cases and longterm disease-free survival was achieved when surgery was curative.CONCLUSIONS:Carcinoid tumors obstructing the biliary tree are extremely difficult to diagnose preoperatively,and nearly impossible to differentiate from non-neuroendocrine tumors.As surgery offers the only potential cure for both biliary carcinoids and cholangiocarcinoma,we recommend aggressive surgical therapy as the treatment of choice in every case of potentially resectable biliary tumor. | Evangelos Felekouras Athanasios Petrou Konstantinos Bramis Evangelos Prassas Ioannis Papaconstantinou Nikoleta Dimitriou Anastasia Pazaiti Christos Tsigris Athanasios Giannopoulos | 2009 | Hepatobiliary & Pancreatic Diseases International2009，8，6： | 5 |
| 2 | Clastic sedimentary features of beachrocks and their palaeo-environmental significance:comparison of past and modern coastal regimes显示文摘Clastic sedimentary features of beachrocks and unconsolidated deposits of parent beaches were investigated along the northern Aegean coastline(Greece) to assess their suitability in palaeo-environmental reconstruction.Twelve paired datasets were collected in the Thermaikos,Toroneos,Siggitikos and lerissos gulfs of the Chalkidiki Peninsula,the adjoining Kavala Gulf and Thassos Island,comprising beachrock cores and companion beach subsurface sediments.Particle size analyses based on univariate and bivariate statistics suggest that,during the time period of beachrock formation,depositional conditions differed distinctly from those of the modern parent beaches.The results imply difference of maturity level of beach evolution from the time of cementation(coarser materials-early stage of beach formation) to modern situation(finer materials-reworked and 'mature' beach sediments).Furthermore,the findings indicate increasing coastal protection due to beachrock exposure in the modern swash zone.In conclusion,it is suggested that textural analysis of beachrocks in comparison with unconsolidated sediments of the parent beach might provide information regarding differences of coastal depositional regimes and future research could focus on specific-layer analysis and comparison. | David PSOMIADIS Konstantinos ALBANAKIS Nikoleta ZISI Matthieu GHILARDI Elissavet DOTSIKA | 2014 | International Journal of Sediment Research2014，29，2： | 3 |
| 3 | Monitoring Greenhouses Gases over China Using Space-Based Observations Monitoring Greenhouses Gases over China Using Space-Based Observations显示文摘The atmospheric carbon dioxide(CO 2)concentration has increased to more than 405 parts per million(ppm.1 ppm=10-6 m/s 2)in 2017 due to human activities such as deforestation,land-use change and burning of fossil fuels.Although there is broad scientific consensus on the damaging consequences of the change in climate associated with increasing concentrations of greenhouse gases,fossil CO 2 emissions have continued to increase in recent years mainly from rapidly developing economies and China is now the largest emitter of CO 2 generating about 30%of all emissions globally.To allow more reliable forecast of the future state of the carbon cycle and to support the efforts for mitigation greenhouse gas emissions,a better understanding of the global and regional carbon budget is needed.Space-based measurements of CO 2 can provide the necessary observations with dense coverage and sampling to provide improved constrains on of carbon fluxes and emissions.The Chinese Global Carbon Dioxide Monitoring Scientific Experimental Satellite(TanSat)was established by the National High Technology Research and Development Program of China with the main objective of monitoring atmospheric CO 2 and CO 2 fluxes at the regional and global scale.TanSat has been successfully launched in December 2016 and as part of the Dragon programme of ESA and the Ministry of Science and Technology(MOST),a team of researchers from Europe(UK and Finland)and China has evaluated early TanSat data and contrast it against data from the GOSAT mission and models.In this manuscript,we report on retrieval intercomparisons of TanSat data using two different retrieval algorithms,on validation efforts for the Eastern Asia region using GOSAT CO 2 data and first assessments of TanSat and GOSAT CO 2 data against model calculations using the GEOS-Chem model. | Hartmut BOESCH Yi LIU Paul I PALMER Johanna TAMMINEN Jasdeep S ANAND Zhaonan CAI Ke CHE Huilin CHEN Xi CHEN Liang FENG Janne HAKKARAINEN Pauli HEIKKINEN Nikoleta KALAITZI Rigel KIVI Robert PARKER Peter SOMKUTI Jing WANG Alex WEBB Dongxu YANG Lu YAO You YI | 2020 | Journal of Geodesy and Geoinformation Science2020，3，4： | 2 |
