BACKGROUND In a previous study, we reported that serpin peptidase inhibitor clade A member 1 (serpinA1) is upregulated in Snail-overexpressing gastric cancer. Although serpinA1 has been studied in several types of cancer, little is known about its roles and mechanisms of action. In this study, we examined the role of serpinA1 in the migration and invasion(More)
AIM To investigate the correlation between implant appearance on ultrasound (US) and voiding cystourethrography (VCUG) results after dextranomer-hyaluronic acid copolymer (DxHA) injection in children with vesicoureteral reflux (VUR). MATERIALS AND METHODS Consecutive cases of primary VUR treated by endoscopic subureteral injection of DxHA were(More)
OBJECTIVE We analyzed the diffusion and perfusion characteristics of acute MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episode) lesions in a large series to investigate the controversial changes of the apparent diffusion coefficient (ADC) that were reported in prior studies. MATERIALS AND METHODS We analyzed 44 newly(More)
PURPOSE To compare the neurodevelopmental outcomes between preterm infants with diffuse excessive high signal intensity (DEHSI) and those without DEHSI on magnetic resonance (MR) images, in association with other white matter lesions. MATERIALS AND METHODS This retrospective study was approved by the institutional review board, and requirement to obtain(More)
BACKGROUND Intraoperative radiofrequency (RF) ablation with or without surgical resection currently plays one of important roles in modern hepatocellular carcinoma (HCC) therapy. We evaluated long-term follow-up results including prognostic factors of intraoperative RF ablation for HCC that was difficult to treat percutaneously. METHODS A total of 133(More)
AIM To evaluate the association between computed tomography (CT) detection of early gastric cancer (EGC) and various parameters, including the depth of invasion, lesion extent, morpholgical type, location, and histological type. MATERIALS AND METHODS One hundred and ten patients with 114 EGCs were preoperatively examined using multidetector CT (MDCT). All(More)
OBJECTIVE The purpose of this study is to investigate the dynamic MRI findings and clinical features of benign hypervascular hepatic nodules in childhood-cancer survivors. MATERIALS AND METHODS We reviewed dynamic MRI findings and clinical features in 15 patients who had been treated for childhood malignant solid tumors and in whom hypervascular hepatic(More)
OBJECTIVE To evaluate the value of the gadobenate dimeglumine-enhanced hepatobiliary-phase magnetic resonance (MR) imaging for the differentiation of scirrhous hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) with or without HCC. MATERIALS AND METHODS We retrospectively evaluated unenhanced and gadobenate dimeglumine-enhanced dynamic and(More)
OBJECTIVE The purpose of our study was to evaluate CT findings to differentiate between T4a and less advanced gastric cancers. METHODS The institutional review board approved this study and waived informed consent. This study included 228 retrospectively identified patients with surgically confirmed gastric cancer (138 T1, 25 T2, 24 T3 and 41 T4a) and who(More)
Smads are signal transducers for the members of the TGF-beta superfamily. Of these Smads, Smad4 is essential for TGF-beta signaling. The purpose of this study was to elucidate Smad4 expression and localization in 65 gastric adenomas, 49 intestinal-type and 39 diffuse type of gastric adenocarcinomas (including 12 cases of fresh frozen tissue) using Real-time(More)
