RATIONALE Impaired endothelial cell-dependent vasodilation, inflammation, apoptosis, and proliferation are manifestations of endothelial dysfunction in chronic obstructive pulmonary disease (COPD). Prostacyclin (PGI(2)) is a major product of the cyclooxygenase pathway with potent vasodilatory and antimitogenic properties and may be relevant to endothelial(More)
STUDY OBJECTIVES Strokes and neurocognitive dysfunction have been correlated with cerebral microemboli produced during cardiopulmonary bypass (CPB). The purpose of this study was to determine whether, and to what extent, off-pump coronary artery bypass (OPCAB) reduces the occurrence of cerebral microemboli compared with traditional coronary artery bypass(More)
A beneficial radioprotective agent has been used to treat the radiation-induced lung injury. This study was performed to investigate whether curcumin, which is known to have anti-inflammatory and antioxidant properties, could ameliorate radiation-induced pulmonary inflammation and fibrosis in irradiated lungs. Rats were given daily doses of intragastric(More)
Chronic airway inflammation is a characteristic feature of destructive cigarette smoking (CS)-induced lung disease, particularly in patients with emphysema. Celecoxib, a specific cyclooxygenase-2 (COX-2) inhibitor, is widely used to treat inflammation. However, the exact mechanisms underlying this drug's anti-inflammatory effects have not yet been(More)
BACKGROUND The diagnosis and treatment of latent tuberculosis infection (LTBI) have become mandatory to reduce the burden of tuberculosis worldwide. Close contacts of active TB patients are at high risk of both active and LTBI. The aim of this study is to identify the predominant risk factors of contracting LTBI, persons in close contact with TB patients(More)
We have demonstrated that VEGF receptor blockade in combination with chronic hypoxia causes in rats severe angioproliferative pulmonary hypertension (SAPH) associated with arterial occlusion by proliferating endothelial cells, and we postulate that the established, lumen-occluding lesions are the result of the emergence of apoptosis-resistant proliferating(More)
OBJECTIVE To evaluate the efficacy of bilateral transthoracic endoscopic sympathectomy (TES), in alleviating symptoms and improving quality of life for patients in Hawaii. DESIGN Retrospective cohort study. MATERIALS AND METHODS Patients who had undergone TES were evaluated by phone interview and the SF-36 questionnaire to assess improvements in(More)
Increasing antioxidant capacity has been proposed as a promising strategy to prevent cigarette smoke-induced lung diseases. This study tested whether garlic extracts prevented cigarette smoke extract (CSE)-induced cell death in human bronchial smooth muscle cells (HBSMCs). Garlic extracts were prepared from fresh raw garlic (FRG), aged black garlic (ABG)(More)
We investigated the role of the lymphocyte-to-monocyte ratio (LMR) at diagnosis in patients with small cell lung cancer (SCLC) treated with standard chemotherapy. We retrospectively reviewed all SCLC patients who received frontline platinum-based chemotherapy or chemoradiotherapy. The cut-off LMR value at diagnosis was 4.19 according to time-dependent(More)
BACKGROUND AND OBJECTIVE Recently, angiopoietin-2 (Ang-2) was identified as a ligand of the endothelial receptor tyrosine kinase, Tie-2. Ang-2 is an angiopoietin-1 antagonist that plays a role in vascular destabilization and remodelling, which may increase in some diseases. However, serum Ang-2 levels have not been evaluated in patients with COPD. In this(More)
