The sex-linked dwarf (SLD) chicken, which lacks GH receptor (GHR), and its normal littermates provide a useful experimental system to investigate GH-dependent cellular responses. The GH dependence of insulin-like growth factor I (IGF-I) expression in tissues was examined in SLD and normal chickens of the Gifu 20 strain. Four weeks after hatching, the most(More)
A mev-1(kn1) mutant of the nematode Caenorhabditis elegans is defective in the cytochrome b large subunit (Cyt-1/ceSDHC) in complex II of the mitochondrial electron transport chain. We have previously shown that a mutation in mev-1 causes shortened life span and rapid accumulation of aging markers such as fluorescent materials and protein carbonyls in an(More)
A modified formalin test in mice was investigated. The pain response curve induced by 0.5% formalin was biphasic, having 2 peaks, from 0 to 5 min (first phase) and from 15 to 20 min (second phase). A low concentration of formalin was used, allowing the effects of weak analgesics to be detected. Centrally acting drugs such as narcotics inhibited both phases(More)
Vascular endothelial growth factor (VEGF), a major mediator of vascular permeability and angiogenesis, may play a pivotal role in mediating the development and progression of diabetic retinopathy. In the present study, we examined the genetic variations of the VEGF gene to assess its possible relation to diabetic retinopathy in type 2 diabetic patients.(More)
The purpose of this study was to propose reference values, from a viewpoint of prognostic significance, for blood pressure (BP) measured at home with a semiautomated device (home BP measurement) to differentiate normotension and hypertension. We obtained home BP measurements for 1,913 population-based subjects aged 40 years and over in a rural Japanese(More)
An HPLC method was developed for the determination of zonisamide in human breast milk and plasma. Chromatographic separation was achieved using a Develosil CN analytical column with potassium dihydrogenphosphate buffer (pH 3.5 with milk, pH 2.5 with plasma)-acetonitrile as the mobile phase. Zonisamide and 1, 2-benzisoxazole-3-methansulfonamine acetate as(More)
OBJECTIVE To compare the prediction of mortality by ambulatory blood pressure monitoring and screening blood pressure measurements in a general population. DESIGN A prospective cohort study. PATIENTS AND METHODS We obtained blood pressure data for 1542 subjects (565 men and 977 women) aged > or = 40 years who were followed up for up to 8.1 years (mean(More)
The inhibitory actions of eugenol on intracellular Ca2+ concentration ([Ca2+]i) and the contractions induced by excess extracellular K+ concentration ([K+]o) in rabbit thoracic aorta were investigated. Application of excess [K+]o solution (30-90 mM) produced contraction and increased the intensity of the Ca2+ fluorescence signal. Pretreatment with eugenol(More)
Chicken leptin receptor (cOb-R) cDNA has been cloned, sequenced and characterized. The predicted cOb-R preprotein was composed of 1148 amino acids showing approximately 60% sequence identity with the long isoform of mammalian leptin receptor, and contained a putative signal peptide, a single transmembrane domain and the conserved box 1, 2 and 3 motifs in(More)
