Thrombocytopenia is a well-known complication of liver cirrhosis. Although the pathogenesis of thrombocytopenia is not well understood, splenic congestion resulting from portal hypertension is considered the most significant underlying mechanism. Therapeutic measures that lower portal hypertension, such as transjugular intrahepatic portosystemic shunt (TIPS), are expected to improve thrombocyto...

The patients of liver cirrhosis associated with portal vein thrombosis (PVT) can be effectively treated by transjugular intrahepatic portosystemic stent shunt (TIPS). Although the corresponding TIPS procedures have already performed on the patients to different types of PVT, the procedures are not specific and the relationship between different types of PVT and technical success rate of TIPS is...

Time-series analysis is used widely in ecology to study complex phenomena and may have considerable potential to clarify relationships of genetic and demographic processes in natural and exploited populations. We explored the utility of this approach to evaluate population responses to management in razorback sucker, a long-lived and fecund, but declining freshwater fish species. A core populat...

King crabs of the genus Paralithodes are hosts to a new genus and species of commensa! pleustid amphipod off southern California. The dactyls of the walking legs of the amphipod bear a novel structure, a sucker, for adhesion to the host, The new genus is piesiomorphic in many aspects, but aporaorphically modified as a commensal. Most (possibly all) specimens are found on crabs parasitized by th...

In their seminal paper (ACM T. Softw. Eng. Methodol., 6(1) (1997), 1–30), Zave and Jackson established a core ontology for Requirements Engineering (RE) and used it to formulate the “requirements problem”, thereby defining what it means to successfully complete RE. Starting from the premise that the stakeholders of the system-to-be communicate to the software engineer the information needed to ...
