Cholangiocarcinoma (CCA), a lethal malignancy afflicting many thousands of patients throughout the world, develops through a multi-step progression. We have established an oral thioacetamide-induced model of rat CCA recapitulating the histologic progression of human CCA, especially for mass-forming CCA (MF-CCA). Our previous DNA microarray study showed MUC4 is overexpressed in rat CCA. Herein, ...

OBJECTIVE To meta-analyze published data about the diagnostic accuracy of fluorine-18-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET) or PET/computed tomography (PET/CT) for primary tumor evaluation in patients with cholangiocarcinoma (CCa). METHODS A comprehensive literature search of studies published through December 31, 2013, was performed. Pooled sensitivity and specifi...

Cholangiocarcinoma (CCA) is a common carcinoma of the liver, and the majority of patients with CCA have a poor prognosis due to the lack of effective nonsurgical therapies in addition to its rapid progression and inoperability at the time of diagnosis. The development of novel nonsurgical therapeutics that efficiently target CCA could significantly improve the prognosis for patients presenting ...

Congenital choanal atresia (CCA), especially the bilateral form, is a rare neonatal emergency. Its incidence is usually quoted as 1 in 5000 8000 live-births. [1] However, a recent epidemiological study involving more than 2.2 million deliveries suggests that CCA is extremely rare with a calculated incidence of 3 to 9 per 100,000 livebirths. [2] Athena is fascinated by CCA not only due to its ra...

BACKGROUND Promising results have been reported for a urine circulating cathodic antigen (CCA) test for the diagnosis of Schistosoma mansoni. We assessed the accuracy of a commercially available CCA cassette test (designated CCA-A) and an experimental formulation (CCA-B) for S. mansoni diagnosis. METHODOLOGY We conducted a cross-sectional survey in three settings of Côte d'Ivoire: settings A ...

Cholangiocarcinoma (CCA) is the second most common-primary liver cancer. The difficulties in diagnosis limit successful treatment of CCA. At present, histological investigation is the standard diagnosis for CCA. However, there are some poor-defined tumor tissues which cannot be definitively diagnosed by general histopathology. As molecular signatures can define molecular phenotypes related to d...

BACKGROUND Approximately 2-10% of the patients with hepatolithiasis may develop cholangiocarcinoma (CCA). Despite recent advances in the treatment of cancers, the 5-year survival rate for CCA patients currently remains poor, primarily due to early local invasion and distant metastasis of the cancer. This study aimed to investigate miR-200a expression in combined hepatolithiasis and CCA as well ...

In this paper, a new clear channel assessment (CCA) method: cascaded-CCA, is proposed that is apropos for next generation dynamic spectrum access radios. The primary motivation for the proposed approach is to integrate the respective advantages of two ‘standard’ CCA mechanisms (energy detection and preamble detection) to arrive at a new dual-threshold CCA family that can provide greater flexibi...

Symptomatic common carotid artery (CCA) occlusion is an uncommon occurrence that may require surgical intervention. We aim to describe a case of CCA occlusion that presented with the unusual symptom of recurrent syncope. A 69-year-old lady presented with a history of recurrent syncopal episodes and amaurosis fugax associated with left leg weakness. She was found to have a right CCA occlusion on...

Cholangiocarcinoma (CCA) is a cancer of biliary epithelial cell origin, which is prevalent in northeastern Thailand. The majority of patients with CCA are diagnosed at the advanced-stage of the disease. Although the early detection and diagnosis of CCA is critical to improve the prognosis of patients, there are presently no specific tumor markers for CCA. A previous study demonstrated that the ...
