Apoptosis signal-regulating kinase 1 (ASK1) is a mitogen-activated protein that can activate the c-Jun N-terminal and p38 signaling pathways. It plays critical role in cytokine- stress-induced apoptosis. To further characterize mechanism of regulation ASK1 signal, we searched for ASK1-interacting proteins employing yeast two-hybrid method. The assay indicated mouse glutathione S-transferase Mu 1-1 (mGSTM1-1), an enzyme involved metabolism drugs xenobiotics, interacted with ASK1. We...
To determine the added value of hepatobiliary phase images in gadoxetic acid-enhanced magnetic resonance (MR) imaging evaluation hepatocellular carcinoma (HCC).Institutional review board approved this retrospective study and waived informed consent. Fifty-nine patients with 84 HCCs underwent MR examinations that included 20-minute delayed imaging. was performed a 1.5-T system 19 3.0-T 40 patients. A total 113 hepatic nodules were documented for analysis. Three radiologists independently...
Purpose: The International Congress of Oral Implantologists has supported the development this consensus report involving use Cone Beam Computed Tomography (CBCT) in implant dentistry with intent providing scientifically based guidance to clinicians regarding its as an adjunct traditional imaging modalities. Materials and Methods: literature CBCT was systematically reviewed. A PubMed search that included studies published between January 1, 2000, July 31, 2011, conducted. presentations,...
Purpose To identify magnetic resonance (MR) imaging features that enable prediction of early recurrence (<2 years) after curative resection hepatocellular carcinoma (HCC) and to derive a preoperative model. Materials Methods This retrospective study was approved by the institutional review board. The requirement obtain written informed consent waived. A total 268 patients who underwent hepatic for single HCC from January 2008 August 2011 were divided into two cohorts: training cohort, which...
To evaluate the usefulness of radiomic model in predicting early (≤2 years) and late (>2 recurrence after curative resection cases involving a single hepatocellular carcinoma (HCC) 2-5 cm diameter using preoperative gadoxetic acid-enhanced magnetic resonance imaging (MRI), comparison with clinicopathologic model.This retrospective study included 167 patients surgically resected pathologically confirmed HCC (n = 167, training set:validation set 128:39) who underwent MRI between January 2010...
The preoperative assessment of rectal cancer wall invasion and regional lymph node metastasis is essential for the planning optimal therapy. This study was done to determine accuracy clinical usefulness transrectal ultrasonography, pelvic computed tomography, magnetic resonance imaging in staging.A total 89 patients with were examined ultrasonography (n = 89), tomography 69), endorectal coil 73). results obtained by these diagnostic modalities compared histopathologic staging specimens.In...
The purpose of this pictorial essay is to illustrate the various appearances solid pseudopapillary tumor pancreas.Solid pancreas a rare neoplasm usually found in young women. Typical characterized by well-encapsulated mass with varying amounts intratumoral hemorrhage. However, can have an atypical appearance, such as metastasis, ductal obstruction, parenchymal and extracapsular invasion, simulation islet cell tumor, calcification, occurrence male patient. typical manifestations be visualized...
To determine whether peritumoral hypointensity seen on hepatobiliary phase images of preoperative gadoxetate disodium-enhanced magnetic resonance imaging (EOB-MRI) is useful for predicting microvascular invasion hepatocellular carcinoma (HCC).This study was approved by the Institutional Review Board. In all, 104 HCC masses in patients who had undergone EOB-MRI and liver surgery within 1 month after were evaluated. Two radiologists independently recorded presence a phase. Interobserver...
<h3>Background/aims:</h3> To evaluate the relationship between axial length and refractive error peripapillary retinal nerve fibre layer (RNFL) thickness profiles measured using Stratus optical coherence tomography (OCT) in subjects with myopia. <h3>Methods:</h3> Forty-eight eyes of 48 myopic were recruited divided into three groups according to their spherical equivalent (SE): low myopia (−3.0 D<SE<0.0 D), moderate (−6.0 D<SE⩽−3.0 D) high (SE⩽−6.0 groups. All individuals underwent...
<h3>Background:</h3> Persistent significant tricuspid regurgitation (TR) after successful left-sided valve surgery is frequently reported. <h3>Objectives:</h3> To evaluate the incidence, risk factors and clinical impact of development late TR surgery. <h3>Methods results:</h3> 638 patients (356 men, mean age 52 (SD 14) years) who had mild (⩽grade 2/4) underwent without any procedure for were analysed. Development was defined as a increase by more than one grade final ⩾3/4 at follow-up...
To prospectively determine whether perfusion computed tomography (CT) parameters, such as volume transfer constant (K(trans)) between blood plasma and extracellular extravascular space (EES) calculated from dynamic CT data, can be used to predict response of pancreatic cancer concurrent chemotherapy radiation therapy (CCRT).This prospective study was institutional review board approved, written informed consent obtained. Thirty patients with underwent 64-detector row before gemcitabine-based...
Abstract Background This multicentre international randomized trial compared the impact of gadoxetic acid-enhanced magnetic resonance imaging (MRI), MRI with extracellular contrast medium (ECCM-MRI) and contrast-enhanced computed tomography (CE-CT) as a first-line method in patients suspected colorectal cancer liver metastases (CRCLM). Methods Between October 2008 September 2010, CRCLM were to one three modalities. The primary endpoint was proportion for whom further after initial required...
