The purpose of this study was to investigate the effect of image superimposition from surrounding alveolar bone and intraradicular contrast medium on radiographic interpretation of a C-shaped canal system in mandibular second molars. Thirty mandibular second molars with fused roots were collected and stored in 10% formalin solution. After being scanned by(More)
To compare matched paliperidone-ER- and olanzapine-treated schizophrenic patients on measures of glucose and lipid metabolism. Eighty hospitalized patients with schizophrenia (DSM-IV) were randomly assigned to treatment with paliperidone ER or olanzapine for a period of 12 weeks. At baseline and every 4 weeks, we assessed weight, subcutaneous fat, waist and(More)
—In shingled magnetic recording (SMR), the multi-head multitrack (MHMT) detector can better combat the effect of intertrack interference (ITI) than the single-head single-track (SHST) detector. Such a detector, however, has prohibitive implementation complexity. In this paper we propose to use the reduced-state sequence estimation (RSSE) algorithm to(More)
—Multitrack detection for shingled magnetic recording (SMR) using a two-head array system is considered. The channel suffers from intersymbol interference (ISI) in the down-track direction and intertrack interference (ITI) in the crosstrack direction. We propose a practical multihead/multitrack detector that provides a low-complexity approach to adaptive(More)
Although patients with coronary artery disease (CAD) have a high mortality rate, the pathogenesis of CAD is still poorly understood. The purpose of this study was to explore the underlying molecular mechanisms and potential target molecules for CAD. The platelet miRNA (GSE28858) and blood mRNA (GSE42148) expression profiles of patients with CAD and healthy(More)
Mesoporous calcium-silicate nanoparticles (MCSNs) are advanced biomaterials for controlled drug delivery and mineralization induction. Nanosilver-incorporated MCSNs (Ag-MCSNs) were prepared in the present study using both the adsorption and template methods. Both versions of Ag-MCSNs showed characteristic morphology of mesoporous materials and exhibited(More)
Quaternary ammonium methacryloxy silicate (QAMS)-containing acrylic resin demonstrated contact-killing antimicrobial ability in vitro after three months of water storage. The objective of the present double-blind randomised clinical trial was to determine the in vivo antimicrobial efficacy of QAMS-containing orthodontic acrylic by using custom-made(More)
BACKGROUND In this paper, we used the principle of biomimetics to design two-dimensional and three-dimensional bar sections, and used computational fluid dynamics software to numerically simulate and analyse the aerodynamic noise, to reduce drag and noise. METHODS We used the principle of biomimetics to design the cross-section of a bar. An owl wing shape(More)
INTRODUCTION Noninvasive fractional flow reserve (FFR) computed from CT (FFRCT) is a novel method for determining the physiologic significance of coronary artery disease (CAD). Several clinical trials have been conducted, but its diagnostic performance varied among different trials. AIM To determine the cut-off value of FFRCT and its correlation with the(More)
