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)
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)
The baculovirus Bombyx mori nucleopolyhedrovirus (BmNPV) contains five related open reading frames (ORFs). Recent sequence analyses of several other baculovirus genomes reveal that these ORFs belong to a unique multigene family called the baculovirus repeated ORFs (bro) family. Here we have characterized these five genes from BmNPV at the transcriptional(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)
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 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)
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)
INTRODUCTION Little is known about oxyhemoglobin (oxy-Hb) levels in the cerebral tissue during the development of anoxic and ischemic brain injury. We hypothesized that the estimated cerebral oxy-Hb level, a product of Hb and regional cerebral oxygen saturation (rSO2), determined at hospital arrival may reflect the level of neuroprotection in patients with(More)
Coenzyme Q10 (CoQ10) is essential for ATP production in the mitochondria, and is an important antioxidant in every biomembrane and lipoprotein. Due to its hydrophobicity, a binding and transfer protein for CoQ10 is plausible, but none have yet been isolated and characterized. Here we purified a CoQ10-binding protein from human urine and identified it to be(More)
