We consider a particular form of the classical approximate joint diagonalization (AJD) problem, which we call a “sequentially drilled” joint congruence (SeDJoCo) transformation. The problem consists of a set of symmetric real-valued (or Hermitian-symmetric complex-valued) target-matrices. The number of matrices in the set equals their(More)
To investigate the feasibility of 70 kV cerebral CT perfusion by comparing image quality and radiation exposure to 80 kV. Thirty patients with suspected cerebral ischemia who underwent dual-source CT perfusion were divided into group A (80 kV, 150 mAs) and group B (70 kV, 150 mAs). Quantitative comparisons were used for maximum enhancement, signal-to-noise(More)
PURPOSE To compare the accuracy of electron-beam computed tomography (CT) with 3.0- and 1.5-mm section thickness for calcium quantification and the prevalence of coronary calcifications with each. MATERIALS AND METHODS Electron-beam CT images were acquired with nonoverlapping 1.5- and 3.0-mm section thickness. Scans were obtained in an anthropomorphic(More)
BACKGROUND Oriental people usually have a wide midface and a prominent zygoma. Reduction malarplasty is one of the most frequently requested procedures for improvement of the facial contour in the Orient. Some methods involve coronal or preauricular incision for osteotomy, but this increases the likelihood of skin scars and injury to facial nerves, and(More)
Glycogen synthase kinase-3β (GSK-3β), a key regulator of neuronal apoptosis, is inhibited by the phosphorylation of Ser-9/Ser-389 and was recently shown to be cleaved by calpain at the N terminus, leading to its subsequent activation. In this study calpain was found to cleave GSK-3β not only at the N terminus but also at the C terminus, and cleavage sites(More)
Background: We investigated the constituting collateral vessels in cavernous transformation of the portal vein (CTPV) caused by tumor thrombosis of hepatocellular carcinoma (HCC) by using contrast-enhanced spiral computed tomographic (CT) examination. Methods: Fifty-four histopathologically proven HCC patients with tumor thrombosis-induced CTPV were(More)
Neuronal activity shapes the dendritic arbour; however, most of the molecular players in this process remain to be identified. We observed that depolarization-induced neuronal activity causes an increase in the phosphorylation of glycogen synthase kinase-3 (GSK-3)α/β on Ser21/9 in cerebellar granule neurons. Using several approaches, including gene(More)
OBJECTIVES This study was aimed to establish a database of pancreatic fat fractions for healthy men aged 20 to 70 years using double-echo chemical shift gradient-echo magnetic resonance imaging. METHODS The double-echo chemical shift gradient-echo magnetic resonance imaging technique was used in this study. A phantom of fat-water mixtures was established(More)
Delta-like ligand 4 (DLL4)-Notch signaling plays a key role in tumor angiogenesis, but its prognostic value in patients with pancreatic ductal adenocarcinoma (PDAC) remains unclear. Our aim was to determine whether high DLL4 expression is correlated with poor prognosis after curative resection for PDAC. Surgical specimens obtained from 89 patients with PDAC(More)
Amanita exitialis is a lethal mushroom that was first discovered in Guangdong Province, China. The high content of amanitin in its basidiocarps makes it lethal to humans. To comprehensively characterize the A. exitialis transcriptome and analyze the Amanita toxins as well as their related gene family, transcriptome sequencing of A. exitialis was performed(More)
