Genetic risk factors for cholangiocarcinoma (CCA) remain poorly understood. We assessed the effect of single-nucleotide polymorphisms (SNPs) of genes modulating inflammation or carcinogenesis on CCA risk and survival. We conducted a case-control, candidate gene association study of 370 CCA patients and 740 age-, sex-, and residential area-matched healthy controls. Eighteen functional or putativ...
Cholangiocarcinoma (CCA) is a heterogeneous group of malignancies that may develop at any level of the biliary tree. CCA is currently classified into intrahepatic (iCCA), perihilar (pCCA) and distal (dCCA) on the basis of its anatomical location. Notably, although these three CCA subtypes have common features, they also have important inter- and intra-tumor differences that can affect their pat...
In order to determine the diagnostic and prognostic value of miR-26a in Cholangiocarcinoma (CCA), we compared miR-26a levels in serum from 66 CCA patients and 66 healthy controls, which was followed by serum analysis between the pre-operative serum and post-operative serum of these CCA patients. We found the concentration levels of miR-26a in serum of CCA patients were significantly higher than...
Altered miRNA expression could be a determinant of cancer development and/or progression. We aimed to study the role of oncomir miR-21 and tumor suppressor let-7a in the genesis of Opisthorchiasis-associated cholangiocarcinoma (CCA). The results showed that miR-21 was up-regulated while let-7a was down-regulated during cholangiocarcinogenesis in the hamster model and also in human CCA samples. ...
We summarize recent work on learning improved acoustic features, using articulatory measurements that are available for training but not at test time. The goal is to improve recognition using articulatory information, but without explicitly solving the difficult acoustics-to-articulation inversion problem. We formulate the problem as learning a (linear or nonlinear) transformation of standard a...
مقدمه: اختلالات خوردن به عنوان یکی از بیماریهای شایع عصر حاضر که عامل بسیاری از آشفتگی ها در زمینههای گوناگون زندگی جوانان شده است، در تحقیق حاضر در نظر گرفته شده تا رابطه بین اضطراب اجتماعی، ادراک تصویر بدنی و افسردگی با پراشتهایی روانی و کماشتهایی روانی در جوانان را مورد پژوهش قرار دهد. روشکار: نمونه تحقیق شامل 200 نفر دانشجوی دختر و پسر جدیدالورود سال 1393-1392 دانشگاه آزاد اسلامی وا...
Cholangiocarcinoma (CCA) is a very aggressive and lethal tumor, which arises from the epithelial cells of bile ducts. CCA comprises about 3% of all gastrointestinal malignancies and its incidence is on the rise in the recent years. Anatomically, it is classified into intrahepatic, perihilar, or extrahepatic (distal) CCA. There are a number of risk factors associated with CCA including primary s...
Cholangiocarcinoma (CCA) occurs frequently in primary sclerosing cholangitis (PSC). Cyclooxygenase-2 (COX-2) and microsomal prostaglandin E synthase-1 (mPGES-1) induced by inflammation are believed to mediate prostaglandin E2 (PGE2) production thereby promoting carcinogenesis. Their expression in PSC-associated CCA tissues and non-neoplastic bile duct epithelial cells (BDECs) in PSC was investi...
There have been conflicting reports as to the extent that copper-chromium-arsenic (CCA) treatments leach from timber. In New Zealand, vineyards utilise CCA-treated posts at a rate of 579 posts per hectare. This represents a potential CCA burden on the soil of 12, 21, and 17 kg/ha, respectively, for the three elements. Given a replacement rate of 4% per year, the use of CCA-treated posts may res...
Understanding the minimal assumptions from which we can build a publickey encryption scheme secure against chosen-ciphertext attacks (a CCA-secure scheme, for short) is a central question in both practical and theoretical cryptography. Following the large body of work on hardness and correctness amplification, we ask the question of how far we can weaken a CCA-secure encryption scheme so that a...
