An ion-sensitive field-effect transistor (ISFET) glucose sensor with a new membrane structure is fabricated and its characteristics are evaluated in continuous measurement of non-diluted serum glucose. This sensor chip is composed of two ISFETs and a gold electrode. An albumin-glutaraldehyde crosslinked membrane, patterned on one of the ISFET gates and the(More)
Although the vasorelaxation by natriuretic peptide (NP) is much less potent in the vein than in the artery, mechanism underlying the phenomenon remains unknown. Since NP receptor consists of three subtypes with different functions, we determined the mRNA level of each NP receptor subtype in the artery and vein by ribonuclease protection assay. In the aorta,(More)
Although atrial and brain natriuretic peptides are well known to be involved in the regulation of cardiovascular and endocrine functions as circulating hormones, the roles of the C-type natriuretic peptide (CNP) remain unknown. We examined the effects of CNP on the secretion of aldosterone and cyclic nucleotides from bovine adrenal zona glomerulosa cells in(More)
We previously demonstrated that angiotensin converting enzyme (ACE) inhibitor normalizes the up-regulated gene expression of vascular natriuretic peptide type A (NP-A) receptor in hypertensive rats. To elucidate the mechanism, we examined the effect of angiotensin II receptor (AT1) antagonist (TCV-116) and bradykinin receptor (B2) antagonist (Hoe 140) on(More)
The piriform cortex layer II of young-adult rats presents a population of prenatally generated cells, which express immature neuronal markers, such as the polysialylated form of the neural cell adhesion molecule (PSA-NCAM) or doublecortin (DCX), and display structural characteristics of immature neurons. The number of PSA-NCAM/DCX expressing cells in this(More)
In several studies, numerous microvilli were found on the surfaces of malignant tumor cells which had high growth potentials, and some tumor-related antigens were identified on these microvilli. Transferrin receptor (TfR) is expressed in proliferating cells and regarded as a tumor marker. In human carcinoma cell lines (HeLa cells, KB cells, and HSC-7(More)
Biological actions of natriuretic peptide (NP) are determined by the condition of the receptor as well as that of the hormone. Although we previously demonstrated in hypertensive rats the up-regulation of NP-A receptor that mediates various biological actions of NPs, the pathophysiologic significance of NP-C receptor, another subtype thought to be related(More)
