OBJECTIVE To investigate the expressions of different forms of ROS fusions in Chinese patients with cholangiocarcinoma (CCA). METHODS RT-PCR was employed to examine formalin-fixed and paraffin-embedded CCA samples from stage I-IV patients for detection of ROS fusions involving Fused in Glioblastoma (FIG), solute carrier protein (SLC34A2) and major histocompatibility complex class II invariant...
The Common Component Architecture (CCA) provides a means for developers to manage the complexity of large-scale scientific software systems and to move toward a “plug and play” environment for high-performance computing. The CCA model allows for a direct connection between components within the same process to maintain performance on inter-component calls. It is neutral with respect to parallel...
ET Cholangiocarcinoma (CCA) is a rare liver cancer that occurs in 1 or 2 individuals per 100,000 in developed regions. Approximately 2500 new cases are diagnosed in the United States each year. The greatest risk factor for developing this cancer is a diagnosis of primary sclerosing cholangitis (PSC). Among patients with this diagnosis, CCA rates may be as high as 30%. Although its overall incid...
A complexity-theoretic model for public-key steganography with active attacks is introduced. The notion of steganographic security against adaptive chosen-covertext attacks (SS-CCA) and a relaxation called steganographic security against replayable adaptive chosen-covertext attacks (SSRCCA) are formalized. These notions are closely related with CCA-security and RCCA-security for public-key cryp...
اکوسیستم های رودخانه ای در ایران به مقدار اندکی مطالعه شده اند و اطلاعات در مورد آنها بسیار پراکنده و کلی است. بنابراین، ضرورت تمرکز بر روی جنبه های مختلف مطالعه رودخانه ها آشکار و به همین ترتیب مدیریت و حفاظت از آنها لازم و ضروری است. این بررسی، با هدف تهیه اطلاعاتی درباره جمعیت های زیستی کلیدی و پاسخ آنها به متغیرهای محیطی به عنوان مدلی برای رودخانه های شمال ایران (گیلان) انجام شد. در طول 6 م...
biodiversity plays a crucial role in stability and productivity of natural ecosystem. the main goal of this research was to classify ecological groups in steppe rangeland and investigate their relationships with plant diversity indices. therefore, fifty different land unit tracts (lut) were identified in khod-neuk basin, yazd province, iran, in 2010. vegetation and soil samples were taken in th...
In Eurocrypt 2010, Fehr et al. proposed the first sender equivocable encryption scheme secure against chosen-ciphertext attack (NC-CCA) and proved that NC-CCA security implies security against selective opening chosen-ciphertext attack (SO-CCA). The NC-CCA security proof of the scheme relies on security against substitution attack of a new primitive, “cross-authentication code”. However, the se...
OBJECTIVE We sought to create a classification system for pediatric corpus callosal abnormalities (CCA) based upon midline sagittal brain MRI. We used the term CCA for patients with structural variants of the corpus callosum, excluding patients with interhemispheric cyst variant or pure dysplasia without hypoplasia. Currently, no system exists for nonsyndromic forms of CCA, and attempts to crea...
Background: Retrospective comparison of stent patency and survival of patients with unresectable extrahepatic cholangiocarcinoma (CCA) treated by placement of self-expanding metal stents (SEMS) with or without endobiliary radiofrequency ablation (ERFA). Methods: Between January 2010 and September 2014, 76 patients with biliary obstruction caused by unresectable extrahepatic CCA (27 patients wit...
Tropomyosin-related kinase B (TrkB) is a functional signal molecule that correlates with cell survival and epithelial-mesenchymal transition (EMT), which is essential for the invasiveness of malignant cancer cells. While a truncated isoform of TrkB has a dominant negative effect, full-length TrkB with its tyrosine kinase domain is predicted to play a role in cancer progression. Because ovarian ...
