In pigmented rabbits anesthetized with N2O (70%) and halothane (2–4%), Purkinje cells were extracellularly recorded in the flocculus. A large central visual field (60°×60°) was used to optokinetically stimulate either the ipsi- or contralateral eye, and the direction and velocity selectivities of complex spike responses were examined. For optokinetic(More)
Molecular phylogenetic relationships of the wood-feeding cockroach genera Salganea and Panesthia (Blaberidae; Panesthiinae) in East Asian Islands (Ryukyu archipelago and Taiwan Island) were analyzed based on the DNA sequence of the complete mitochondrial cytochrome oxidase II gene. Unweighted parsimony analysis resulted in high bootstrap support for(More)
OBJECTIVE The aim of this study was to assess the relationship between atherotic (structural) and sclerotic (functional) changes in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS Aortic distensibility and carotid intimal-media thickness (IMT) were evaluated using carotid-femoral aortic pulse-wave velocity (a-PWV) and high-resolution B-mode(More)
From 1988 to 1992, 1188 children (576 boys and 612 girls) three to 11 years old were studied using the Stasio-analyzer to clarify developmental change of upright postural sway. Developmental change in the contact surface area of the sole, the coefficient of variation for the contact surface area, total sway area, total sway path and position of the centre(More)
Cardiovascular actions of insulin were studied by intravenous infusions of insulin (4 and 8 mU/kg per min) in normal conscious dogs. This resulted in increases in cardiac output, heart rate, and left ventricular derivative of pressure with respect to time (dP/dt) and dP/dt/P, as blood glucose was reduced. The inotropic and chronotropic effects of insulin(More)
OBJECTIVE To investigate whether the insulin resistance index (IR) assessed by homeostasis model assessment (HOMA) is associated with the insulin resistance index assessed by euglycemic-hyperinsulinemic clamp (clamp IR) in type 2 diabetic patients who received sulfonylureas (SUs), as well as in those treated by diet alone.

We cloned a cDNA for the rat kappa-opioid receptor from a rat thalamus cDNA library. The deduced amino acid sequence consists of 380 residues with features shared by members of the G protein-coupled receptor family. The specific binding of [3H]bremazocine to the membrane of COS-7 cells transfected with the cDNA was displaced by kappa-specific opioid(More)
