Characterization of a cDNA encoding a precursor of Carassius RFamide, structurally related to a mammalian prolactin‐releasing peptide
We have characterized the cDNA encoding Carassius RFamide (C‐RFa), which is structurally related to mammalian prolactin‐releasing peptides (PrRPs), from the brain of the crucian carp. The deduced… Expand

A novel bioactive peptide with the C-terminal RFamide was isolated from the brain of the Japanese crucian carp, Carassius auratus langsdorfii, by using the intestine of the fish as the bioassay… Expand
Fishy tales of prolactin-releasing peptide.
Prolactin (PRL) is an important regulator of multiple biological functions, but a specific PRL-releasing factor, PRL-releasing peptide (PrRP), was isolated only recently from mammals and teleosts.… Expand

In the tilapia (Oreochromis mossambicus), as in many teleosts, prolactin (PRL) plays a major role in osmoregulation in freshwater. Recently, PRL-releasing peptides (PrRPs) have been characterized in… Expand
An analysis of inputs to ON-OFF amacrine cells in the carp retina with kynurenic acid.
Amacrine cell inputs were studied in the carp retina. Responses to light of bipolar and amacrine cells in off-pathways were suppressed by 0.5 mM kynurenic acid (Kyn), while those in on-pathways were… Expand
Field potentials induced by injection of potassium ion into the frog retina: A test of current interpretations of the electroretinographic (ERG) b-wave
Using excised frog retinas, the field potential induced by mechanical intraretinal injection of K+ Reinger's was mapped by a penetrating electrode. The high K+ Ringer's contained 75 mM K+ and the… Expand
Two S-Iamide Peptides, AKSGFVRIamide and VSSFVRIamide, Isolated from an Annelid, Perinereis vancaurica.
Two peptides, H-Ala-Lys-Ser-Gly-Phe-Val-Arg-Ile-NH2 (AKSGFVRIamide), and H-Val-Ser-Ser-Phe-Val-Arg-Ile-NH2 (VSSFVRIamide) were isolated from a polychaete annelid, Perinereis vancaurica. Both the… Expand

Neuropeptide FF, one of the mammalian PQRFamides, has been reported to affect the latency of the tail-flick response in rat. We intended to examine the nociceptive effect by the peptide PQRFamides… Expand
Relationship between pollen counts of Cryptomeria japonica and Cupressaceae and the severity of allergic symptoms
ABSTRACT Background A study throughout 1999 of the airborne pollens of both Cryptomeria japonica and Cupressaceae (Chamaecyparis obtusa and Juniperus rigida in the present study) demonstrated unique… Expand
