A facile one-pot synthesis of d-glucuronic acid-coated ultrasmall Ln(2)O(3) (Ln = Eu, Gd, Dy, Ho, and Er) nanoparticles is presented. Their water proton relaxivities were studied to address their possibility as a new potential MRI contrast agent. We focused on the Dy(2)O(3) nanoparticle because it showed highest r(2) relaxivity among nanoparticles. Its performance T(2) agent was for first time proved in vivo through its 3 T MR images mouse, showing that can be further exploited rational...
A facile one-pot synthesis of a water-soluble MnO nanocolloid (i.e., D-glucuronic acid-coated nanoparticle) is presented. The nanoparticle in the was coated with biocompatible and hydrophilic acid, its particle diameter nearly monodisperse ranged from 2 to 3 nm. average hydrodynamic estimated be 5 paramagnetic down T=3 K. showed high longitudinal water proton relaxivity r1=7.02 s(-1) mM(-1) r2/r1 ratio 6.83 due five unpaired S-state electrons Mn(II) ion (S=5/2) as well surface volume...
Abstract The construction of multilevel magnetic states using materials with perpendicular anisotropy (PMA) offers a novel approach to enhancing the storage density and read/write efficiency nonvolatile memory devices. In this study, optically readable domain are achieved by inducing asymmetric interlayer interactions decoupling reversal behavior individual ferromagnetic (FM) layers in exchange‐biased FM multilayers PMA. Hepta‐level formed [Co/Pt] n grown on an antiferromagnetic Fe 2 O 3...
Background/Aim: Primary retroperitoneal squamous cell carcinoma (PRSCC) is extremely rare, and its diagnosis management are challenging. Previous reports have highlighted the potential role of human papillomavirus (HPV) in pathogenesis PRSCC. This study aimed to determine clinicopathological molecular characteristics Patients Methods: We searched PubMed for previously published PRSCC cases. Immunostaining, testing, targeted DNA RNA sequencing were performed. Results: A total 25 cases...
ABSTRACT Background The diagnosis of oral squamous cell carcinoma (OSqCC) is sometimes delayed. In this study, we attempted to comprehensively analyze the surface and cross section OSqCC using whole‐mount sections. Methods Representative sections 41 pT2 pT3 were digitally assembled, reconstructed. tumor, degree differentiation was classified as well/moderately differentiated (WDMD) poorly (PD); specimen divided into four types: benign‐looking epithelium, dysplasia, carcinoma, ulceration....
Guanine nucleotide binding protein (G-protein) beta polypeptide 3 (GNB3) C825T polymorphism alters intracellular signal transduction, which may lead to motor or sensory abnormalities of the gastrointestinal tract. The aim present study was evaluate association GNB3 with susceptibility overlap syndrome functional dyspepsia (FD) and irritable bowel (IBS) in a Korean population.One hundred sixty-seven patients FD alone, 60 IBS 85 IBS, 434 asymptomatic healthy subjects participated study....
Background/Aims Apolipoprotein E (ApoE) plays an important role in regulating lipid and lipoprotein metabolism, ApoE genotypes are known to affect plasma concentrations. We investigated whether genotype determines the disease outcome hepatitis B virus (HBV)-infected individuals, verified association between occurrence of hepatocellular carcinoma (HCC) patients with chronic liver diseases various etiologies. Methods This hospital-based, case-controlled study enrolled 156 subjects (47 healthy...
The aim of this study was to capture multifaceted clinical characteristics congenital cytomegalovirus (CMV) infection from diagnosis treatment using a multidisciplinary approach including obstetrics, pediatrics, pathology, and otorhinolaryngology-head neck surgery.This is retrospective 30 consecutive cases CMV that were diagnosed at single tertiary hospital located in Seoul, Korea January 2009 December 2020. Congenital defined as positive result by polymerase chain reaction urine, saliva or...
The surface tension of 430 stainless steel was measured using an electromagnetic levitation (EML) method at temperatures 1707–2000 K, under a 5 vol% H2–He atmosphere. For comparison, the also constrained drop method; specifically advanced sessile method. At 1823 estimated from and methods to be 1.802 1.614 N/m, respectively. A subsequent analysis oxygen content showed that former contained ~7 ppm oxygen, whereas latter had 60 ppm. It therefore considered observed difference in measurements...
Background and aim The of this study was to determine whether dynamic computed tomography (CT)-measured liver volume predicts the risk hepatocellular carcinoma (HCC) when CT scans do not reveal evidence HCC in chronic hepatitis B (CHB) patients on surveillance. Methods This retrospective multicentre cohort included 1,246 who received entecavir regular surveillance three tertiary referral centres South Korea. Liver volumes were measured portal venous phase images. A nomogram developed based...
Background/Aim: Insulin-like growth factor II mRNA-binding protein 3 (IMP3) plays an important role in the adhesion, invasion, and metastasis of tumor cells. Although emerging evidence suggests that IMP3 promotes progression several malignancies, expression its prognostic implication adenocarcinoma ampulla Vater (AVAC) has not been clarified to date. Materials Methods: The status 87 AVAC tissues was examined using immunostaining, association with various clinicopathological features outcome...
