Estrogen receptors are widely expressed in the brain, where estrogen modulates central nervous function. In this study, we investigated the effect of estrogen on the emotional stress response in the brain by comparing the CNS patterns of c-Fos expression in response to immobilization stress (IMO) in ovariectomized rats with placebo treatment (OVX + Pla) vs.(More)
BACKGROUND/PURPOSE Critical recurrences after radiofrequency ablation for hepatocellular carcinoma (HCC), such as intrahepatic metastases or dissemination, and extrahepatic metastases or seeding, which are difficult to treat radically, almost certainly lead to primary cancer death. The present study aimed to clarify whether the arterial tumor enhancement(More)
The aim of the present study was to predict sustained virological response (SVR) to telaprevir with pegylated interferon (PEG-IFN) and ribavirin using viral response within 2 weeks after therapy initiation. Thirty-six patients with genotype 1 hepatitis C virus (HCV) and high viral load were treated by telaprevir-based triple therapy. SVR was achieved in 72%(More)
The present study aimed to elucidate the association between post-vascular-phase (Kupffer-phase) images from contrast-enhanced ultrasonography (CEUS) with perfluorobutane microbubbles and metastatic recurrences after the resection of hepatocellular carcinoma (HCC). The study examined 73 patients with solitary HCC ≤5 cm in diameter who underwent CEUS before(More)
OBJECTIVES The role of contrast-enhanced sonography in the diagnosis of recurrent hepatocellular carcinoma is still unclear. This study aimed to clarify the usefulness and limitations of contrast-enhanced sonography with a perfluorobutane microbubble contrast agent (Sonazoid; Daiichi-Sankyo, Tokyo, Japan) after contrast-enhanced computed tomography (CT) for(More)
OBJECTIVES To investigate the usefulness of contrast-enhanced endoscopic ultrasonography (CE-EUS) for histological differentiation of pancreatic tumors. METHODS CE-EUS was performed for consecutive patients having a pancreatic solid lesion, and tumors were classified into three vascular patterns (hypervascular, isovascular, and hypovascular) at two time(More)
OBJECTIVES An ultrasound contrast agent consisting of perfluorobutane microbubbles (Sonazoid; Daiichi Sankyo, Tokyo, Japan) accumulates in Kupffer cells, which thus enables Kupffer imaging. This study aimed to elucidate the association of defect patterns of hepatocellular carcinoma during the Kupffer phase of Sonazoid contrast-enhanced sonography with(More)
S18 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 and adenocarcinoma was detected. None of the lesions had mucinous morphology. There were no periprocedural complications. Conclusion: EUS is an effective modality to detect occult primary in patients with CUPS with suspected pancreaticobiliary origin. Larger studies assessing its(More)
