Epidemiological studies suggest that lung cancer, which is a major cause of cancer death, has a critical association with cigarette smoking. Tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) in cigarette smoke is a major risk factor for carcinogenesis. However, the mechanisms by which NNK promotes cancer development have not been fully elucidated. Growing evidence suggests that lung cancer originates from cancer stem cells (CSCs), which are a minor population of lung cancer cells...

The present study investigated the effects of diesel exhaust (DE) on an experimental model of bleomycin (BLM)-induced lung injury and fibrosis in mice. BLM was intravenously administered to both Nrf2(+/+) and Nrf2(-/-) C57BL/6J mice on day 0. The mice were exposed to DE for 56 days from 28 days before the BLM injection to 28 days after the BLM injection. Inhalation of DE induced significant inhibition of airway clearance function and the proinflammatory cytokine secretion in macrophages, an increase in neutrophils, and severe lung inflammatory injury, which were greater in Nrf2(-/-) mice than in Nrf2(+/+) mice...

BACKGROUND AND PURPOSE: Although risk factors for acute coronary syndrome (ACS) and atherothrombotic cerebral infarction (ACI) are common, it is unknown if the risk factors for these two conditions are similar. The purpose of our study was to elucidate differences in carotid artery atherosclerotic features between ACS and ACI. METHODS: We measured carotid artery ultrasound-based atherosclerotic parameters in 61 ACS and 33 ACI patients. In the ACS patients, 31 had single-vessel coronary artery disease (SVD) and 30 had multivessel coronary artery disease (MVD)...

Donor-independent platelet concentrates for transfusion can be produced in vitro from induced pluripotent stem cells (iPSCs). However, culture at 37°C induces ectodomain shedding on platelets of glycoprotein Ibα (GPIbα), the von Willebrand factor receptor critical for adhesive function and platelet lifetime in vivo, through temperature-dependent activation of a disintegrin and metalloproteinase 17 (ADAM17). The shedding can be suppressed by using inhibitors of panmetalloproteinases and possibly of the upstream regulator p38 mitogen-activated protein kinase (p38 MAPK), but residues of these inhibitors in the final platelet products may be accompanied by harmful risks that prevent clinical application...

BACKGROUND: Pathologic subjective halitosis is known as a halitosis complaint without objective confirmation of halitosis by others or by halitometer measurements; it has been reported to be associated with social anxiety disorder. Olfactory reference syndrome is a preoccupation with the false belief that one emits a foul and offensive body odor. Generally, patients with olfactory reference syndrome are concerned with multiple body parts. However, the mouth is known to be the most common source of body odor for those with olfactory reference syndrome, which could imply that the two conditions share similar features...

BACKGROUND: The use of video-assisted thoracoscopic surgery (VATS) has substantially increased in recent years. These procedures involve the insertion of specialized devices into the thoracic cavity via access ports. However, conventional devices such as cotton-tipped applicators and graspers can limit the field of view and injure the fragile lung tissue. The aim of this study was to develop a novel lung-stabilizing device for VATS that provides a good surgical field of view without causing lung injury...
