BACKGROUND Amino acids (AAs) are emerging as a new class of effective molecules in the etiology of obesity and diabetes mellitus. However, most investigations have focused on subjects with obesity and/or impaired glucose regulation; the possible involvement of AAs in the initial phase of glucose dysregulation remains poorly understood. Furthermore, little(More)
BACKGROUND The accuracy of echocardiographic parameters of right ventricular (RV) function has not been sufficiently validated in patients with pulmonary hypertension (PH). The aim of this study was to evaluate whether echocardiographic measurements reliably reflect RV systolic function in PH using cardiac magnetic resonance imaging (CMRI)-derived RV(More)
The cytokine "macrophage migration inhibitory factor (MIF)" is generally recognized as a proinflammatory cytokine, and MIF is involved in broad range of acute and chronic inflammatory states. With regard to glucose metabolism and insulin secretion, MIF is produced by pancreatic β cells and acts as a positive regulator of insulin secretion. In contrast, it(More)
We encountered a 69-year-old woman displaying a filling defect within the left descending pulmonary artery (PA) on a chest CT scan and pulmonary angiography. A subsequent 2-[18F]fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET) scan demonstrated focal uptake in the left hilum. A cytologic examination of transbronchial needle aspiration(More)
