Alveolar macrophages constitutively reside in the respiratory tracts of pigs and humans. An in vivo role of alveolar macrophages in defending against influenza viruses in mice infected with a reassorted influenza virus, 1918 HA/NA:Tx/91, was reported, but there has been no report on an in vivo role of alveolar macrophages in a natural host such as a pig(More)
Swine influenza viruses are an important pathogen in pig industry. In this study, we wanted to know whether swine H1N2 influenza viruses circulating in Korean pigs would cause clinical signs in pigs when experimentally infected. When pigs were infected with swine H1N2 viruses isolated from Korean pigs, pigs suffered from severe clinical signs of coughing,(More)
The highly pathogenic H5N1 influenza viruses are one of candidates for the next pandemic. Information on protective immunity for pregnant animals by vaccination against the H5N1 influenza virus is limited. Here, we show that the immunization of pregnant mice with inactivated H5N1 influenza vaccine protects them, their fetuses, and their infant mice from(More)
Swine-origin pandemic 2009 A (H1N1) influenza viruses are still infecting humans, and humans are currently being vaccinated with the inactivated vaccine of 2009 A (H1N1) influenza virus. We wanted to determine the efficacy of 2009 A (H1N1) inactivated vaccine in ferrets. Ferrets immunized with one dose (7.5 microg) of 2009 A (H1N1) inactivated vaccine were(More)
INTRODUCTION The purpose of this study was to determine whether a displaced dorsal rim fracture has an adverse effect on wrist function after volar plate fixation of a dorsally displaced distal radius fracture (DRF). MATERIALS AND METHODS Two matched cohorts of 23 matched patients, one with a displaced dorsal rim fracture >2mm (group 1), and the other(More)
The highly pathogenic H5N1 influenza viruses are endemic in poultry in many countries, but continuously infect humans and cause human mortality. H5N1 influenza viruses have been regarded as a pandemic candidate. In a pandemic event by this virus, the protection of poultry with an effective vaccine will help to greatly reduce the spread of this virus to(More)
Transmission electron microscopy images showed that ZnO nanoparticles were randomly distributed inside the polymethyl methacrylate (PMMA) layer. Capacitance-voltage (C-V) measurements on the Al/ZnO nanoparticles embedded in a PMMA layer/C60/p-Si diode at 300 K showed a clockwise hysteresis with a flatband voltage shift due to existence of the ZnO(More)
BACKGROUND/AIMS This study investigated the use of the BRAVO catheterless pH monitoring system to determine the effective administration method of intravenous proton pump inhibitor and the effectiveness of 80 mg pantoprazole per day on the regulation of gastric acid. METHODS A total of 32 patients who underwent endoscopic resection were randomly assigned(More)
H1N2 influenza viruses are circulating in pigs worldwide and cause considerable economic losses to the pig industry. We genetically analyzed the genes of our isolates from Korean pigs, and compared the antigenicity of our isolates with swine H1N2 viruses isolated from pigs in the U.S.A. In addition, we serologically surveyed the infection rate of swine H1N2(More)
Scanning electron microscopy images showed that self-assembled ZnO nanoparticles were created inside a poly-4-vinyl-phenol (PVP) layer. Current-voltage (I-V) measurements on the Al/ZnO nanoparticles embedded in a PVP layer/indium tin oxide (ITO)/glass device fabricated by using a simple spin coating method at 300 K showed an electrical hysteresis behavior,(More)
