Pulmonary macrophages are one of the sources of various antioxidant and detoxification enzymes for which NF-E2-related factor 2 (Nrf2) is a key transcriptional factor. Although Nrf2 deficiency reportedly induces severe emphysema in mice exposed to cigarette smoke (CS), no reports have studied Nrf2 regulation in chronic obstructive pulmonary disease (COPD).(More)

INTRODUCTION The value of measuring procalcitonin (PCT) in patients with community-acquired pneumonia (CAP) is unclear. The aim of this study was to determine the value of PCT as a marker for microbial etiology and a predictor of outcome in CAP patients. METHODS A single-center observational study was conducted with CAP patients. On admission, their(More)
Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease consisting of emphysema, small airway obstruction, and/or chronic bronchitis that results in significant loss of lung function over time. In order to gain insights into the molecular pathways underlying progression of emphysema and explore computational strategies for identifying COPD(More)
Exacerbations are among the major factors that may affect the natural history of chronic obstructive pulmonary disease (COPD). The aim was to investigate the clinical characteristics and determinants of COPD exacerbations in our 5-year observational cohort study which had a very low exacerbation frequency. A total of 279 patients with COPD participated in(More)
PGE(2) has been reported to inhibit allergen-induced airway responses in sensitized human subjects. The aim of this study was to investigate the mechanism of anti-inflammatory actions of PGE(2) in an animal model of allergic asthma. BN rats were sensitized to OVA using Bordetella pertussis as an adjuvant. One week later, an aerosol of OVA was administered.(More)
BACKGROUND We encountered eight early amnestic mild cognitive impairment (aMCI) patients (early MCI group) who did not fulfill the diagnostic criteria for aMCI. We compared the scores of neuropsychological examinations as well as the cerebral metabolic rate for glucose consumption (CMRglc) decrease on (18)F-FDG PET examination between the early MCI group(More)
BACKGROUND All clinical and biological manifestations related to postcardiac arrest (CA) syndrome are attributed to ischemia-reperfusion injury in various organs including brain and heart. Molecular hydrogen (H(2)) has potential as a novel antioxidant. This study tested the hypothesis that inhalation of H(2) gas starting at the beginning of cardiopulmonary(More)
BACKGROUND Although metabolic reduction in the primary visual cortex on [(18) F]-fluoro-d-glucose (FDG) positron emission tomographic (PET) scans is the hallmark of dementia with Lewy bodies (DLB) for differential diagnosis from Alzheimer's disease, the clinical significance of the metabolic pattern in patients without dementia remains unknown. The purpose(More)
BACKGROUND Previous longitudinal studies have revealed that specific patterns on [(18) F]-fluoro-d-glucose (FDG) positron emission tomography (PET) scans in patients with amnesic mild cognitive impairment can predict Alzheimer's disease (AD). However, the significance of particular patterns on [(18) F]-FDG PET scans in prodromal patients with dementia with(More)
