OBJECTIVE Kawasaki disease (KD) was first reported by Tomisaku Kawasaki in 1967 in Japan. Large-scale nationwide epidemiologic surveys have been conducted continuously by the Japan Kawasaki Disease Research Committee; however, there were very few reports of KD before 1967. This study was performed to clarify when KD appeared in Japan. DESIGN We(More)
In this study, we demonstrated that the two ginger-derived components have a potent and unique pharmacological function in 3T3-L1 adipocytes via different mechanisms. Both pretreatment of 6-shogaol (6S) and 6-gingerol (6G) significantly inhibited the tumor necrosis factor-alpha (TNF-alpha) mediated downregulation of the adiponectin expression in 3T3-L1(More)
Age-associated changes in pulsatile components of the arterial system in normal children have not previously been studied. The purpose of the present study was to establish reference ranges for age-associated changes in arterial pulsatile properties in children. Arterial compliance (CA) and stiffness of the proximal aorta were estimated from data obtained(More)
Previous studies have documented the normal values of pulmonary arterial compliance (Cp) in animals and adult humans. In the past, variations in Cp and its measurement in children with septal defects has been unknown. In the present study, we found the Windkessel model, which uses compliance and resistance as parameters, to be a useful tool in understanding(More)
The development and regression of the coronary aneurysms in Kawasaki disease was studied with serial two-dimensional echocardiographic (2D echo) examinations. The diameter of the aneurysms at the proximal portions of the left coronary artery was measured on the 2D echo images in ten patients with Kawasaki disease, in whom left coronary aneurysms were found(More)
BACKGROUND Previous reports suggest that Brazilian propolis has multiple biological functions and may help to restore adiponectin expression and insulin sensitivity. However, little is known about the molecular mechanisms by which these compounds inhibit the downregulation of adiponectin. METHODS The effect of various Brazilian propolis-derived components(More)
To clarify the phenotypes of various classes of human hematopoietic progenitor cells, we used a multicolor staining protocol in conjunction with CD34 and a newly developed mouse antihuman c-kit proto-oncogene product (KIT) monoclonal antibody (MoAb). We characterized three cell fractions in CD34+ cells that express K171" and KIFigh cells in addition to(More)
SCOPE Previous reports suggest that soy isoflavones have multiple biological functions and may help to restore adiponectin expression and insulin sensitivity. However, little is known about whether soy isoflavones can inhibit the downregulation of adiponectin and their molecular mechanisms. In the present study, we demonstrate that genistein (Gen) or(More)
