A series of C-terminal linear peptides of endothelin (ET)-1 and their N alpha-succinyl (Suc) analogs were synthesized and their binding affinities for the two subtypes of ET receptor, ETA and ETB, in porcine lung membranes were examined. Among the synthetic analogs, Suc-[Glu9,Ala11,15]-ET-1(8-21), IRL 1620, was the most potent and specific ligand for the(More)
To investigate the neural substrates for naming objects and their category-dependency, we performed functional magnetic resonance imaging (fMRI) with naming of animals and tools. Naming objects, irrespective of their category, activated left frontal to bilateral parietal regions and occipital to posterior temporal regions. Within these areas, naming animals(More)
We tried to identify the mechanisms directly related to syntactic processing in an fMRI experiment using strictly controlled sets of verbal stimuli. In two conditions, center-embedding and left-branching conditions, the same sets of words were used to construct stimulus sentences, while only the word order reflecting their syntactic structure was different.(More)
Midkine (MK) is a 13 kDa heparin-binding polypeptide which enhances neurite outgrowth, neuronal cell survival and plasminogen activator activity. MK is structurally divided into two domains, and most of the biological activities are located on the C-terminal domain. The solution structures of the two domains were determined by NMR. Both domains consist of(More)
Prognostic factors for low-grade astrocytomas have been proposed, but optimal treatment remains controversial. Eighty-eight consecutive adult patients with supratentorial low-grade astrocytomas were retrospectively reviewed to determine specific factors influencing outcome. All underwent craniotomy (43 radical resections, 45 nonradical resections). Sex, age(More)
From this study, we predicted that the human calcitonin gene-related peptide (hCGRP) fragment hCGRP-(8-37) would be a selective antagonist for CGRP receptors but an agonist for calcitonin (CT) receptors. In rat liver plasma membrane, where CGRP receptors predominate and CT appears to act through these receptors, hCGRP-(8-37) dose dependently displaced(More)
Vascular smooth muscle cells (VSMC) from rat aorta possess specific receptors for a novel potent vasorelaxant peptide, adrenomedullin (AM). To elucidate its receptor coupling to guanine nucleotide-binding stimulatory protein and the structural requirement of the AM molecule to its vascular receptors, we have studied the effects of guanine nucleotides on(More)
The mechanisms involved in visual object recognition from non-canonical viewpoints were investigated using functional magnetic resonance imaging (fMRI). We used a passive observation task and found three areas activated more strongly in the non-canonical viewing condition compared with the canonical viewing condition. First, it was found that the fusiform(More)
1. Pharmacokinetic properties of difloxacin have been studied in pig and chicken after intravenous and oral administration. 2. The serum concentrations of difloxacin in pig and chicken after intravenous administration were best described by a two-compartment open model, giving distribution half-lives of 0.50 and 0.66 h and elimination half-lives of 7.92 and(More)
A functional magnetic resonance imaging experiment at 3 tesla was performed to investigate the collaborative mechanism between visuospatial processing and motor execution in performing visual language generation tasks. Japanese Kanji, ideographic characters, were utilized to design tasks. The bilateral border portions between the inferior parietal lobule(More)
