Sera from 27 children and eight older persons, which had been collected in 1998 and 1999 and showed haemagglutination-inhibition (HI) activity against influenza A/Sydney/5/97 (H3N2) strain, were characterized with a binding assay using chimeric haemagglutinin (HA) proteins between A/Aichi/2/68 (A/AI/68) and A/Sydney/5/97 (A/SD/97) strains. Sera from the(More)
An elevated level of adenosine deaminase (ADA) in pleural liquid has been considered as a supplemental diagnostic marker for tuberculous pleurisy. However, this is complicated by false-positives and -negatives. Recently, it has been revealed that various cytokines are intimately involved in the pathognomonic physiology of tuberculosis. In this study,(More)
In an effort to find efficient DNA vaccine candidates, cDNA of influenza A virus hemagglutinin (HA) gene and several derived mutants were injected into mice using a gene gun. Mice immunized with HA1 DNA, with or without a membrane domain, showed a humoral immune response and the survival rate against homologous virus challenge was comparable to that of mice(More)
A 53-year-old female with mild shock due to vomiting and abdominal pain visited the emergency room of our hospital. Chest X-ray on admission showed a large amount of left pleural effusion. Thoracentesis revealed hemorrhagic pleural effusion. An upper gastrointestinal series showed interruption of the upper gastric body, but the anal side was not visualized.(More)
We introduced 248 single-point amino acid changes into hemagglutinin (HA) protein of the A/Aichi/2/68 (H3N2) strain by a PCR random mutation method. These changes were classified as positive or negative according to their effect on hemadsorption activity. We observed following results. (i) The percentage of surviving amino acid changes on the HA1 domain(More)
Exposure to asbestos results in serious risk of developing lung and mesothelial diseases. Currently, there are no biomarkers that can be used to diagnose asbestos exposure. The purpose of the present study was to determine whether the levels or detection rate of chemokine (C-C motif) ligand 3 (CCL3) in the serum are elevated in persons exposed to asbestos.(More)
BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa are the main causes of refractory infections that are often resistant to antimicrobial agents. In these cases, combination of agents with antimicrobial activity is being examined. However, few studies have investigated combined effects with antimicrobial agents(More)
We encountered a case of obstructive pneumonia 1 month after peanut aspiration. Bronchoscopic examination revealed obstruction of the right basal bronchus with immature granulation tissue due to the peanut aspiration. Despite antibiotic treatment, the obstruction had not been resolved. To relieve the bronchial obstruction, bronchoscopic intralesional(More)
In cytochrome c, the coordination of the axial Met Sδ atom to the heme Fe atom occurs in one of two distinctly different stereochemical manners, i.e., R and S configurations, depending upon which of the two lone pairs of the Sδ atom is involved in the bond; hence, the Fe-coordinated Sδ atom becomes a chiral center. In this study, we demonstrated that an(More)
A 65-year-old man with pneumoconiosis visited our hospital for dyspnea on effort. Chest radiography and computed tomography on admission showed cavities with an air-fluid level, consolidation in the right lower lung, and right pleural effusion. The thoracic cavity and an infected cyst were drained, and antibiotics were administered. On detection of molds(More)
