Prostaglandins, 1990
The present experiment was undertaken to investigate the seasonal variations of levels of prostaglandins (PGs) and regulation of these levels in the ovary and hemolymph of the scallop. The levels of prostaglandin F2 alpha (PGF2 alpha) and prostaglandin E2 (PGE2) in the hemolymph and ovary increased during sexual maturation, and these levels in the ...

Marine sterols. VI(1). Sterols of the scallop, Patinopecten yessoensis
Steroids, 1975The sterols of the scallop, Patinopecten yessoensis Jay, was found to contain over 20 components. The major components were delta5-sterols, and lesser amount of ring-saturated sterols were also present. Biogenetically unusual C26 sterols (24-norcholesta-5,22-dien-3beta-ol and 24-norcholest-22-en-3beta-ol) and 24(28)-cis-24-propylidenecholest-5-en-3beta-

Structure of Patinopecten Yessoensis Shell is a Biomimetic Example of Composite
Advanced Materials Research, 2012Shell is a natural composite material with excellent mechanical property. it is a model of biomimetic composites. In the paper, the morphology of the scallop (patinopecten yessoensis) shell was observed by SEM. The results are shown that the shell is composed by the tertiary structure.

Structural analysis of a polysaccharide from Patinopecten yessoensis viscera
European Food Research and Technology, 2009A water-soluble polysaccharide, SVP-2, was obtained from Patinopecten yessoensis viscera. Its major structural features were elucidated using composition analysis, methylation analysis, periodate oxidation and Smith degradation, partial acid hydrolysis, and NMR spectroscopy. The results indicated that SVP-2, with an average molecular weight of 170 kDa,

Developmental & Comparative Immunology, 1985
In vitro production of hydrogen peroxide (H2O2) by the amoebocytes of the scallop, Patinopecten yessoensis, was studied. The authors first confirmed the availability of the direct quantitative method using homovanillic acid, and found that both resting and stimulated amoebocytes produced H2O2.

Some glycolytic metabolites in the adductor muscle were measured after transfer of scallops from aerobic to anaerobic saltwater for 12 h. The level of octopine increased gradually during the initial 3 h incubation, and thereafter the level increased rapidly up to 12 h. The ATP level also did not show any significant change for the initial 3 h, and then

Stock enhancement of the Japanese scallop Patinopecten yessoensis in Hokkaido
Fisheries Research, 2006Prior to the early 1940s, harvests of scallops from Japan fluctuated from ∼10 to 80,000 tonnes per anum. However, the fishery collapsed in 1945 and production remained at chronically low levels (

Physiological energetics of Japanese scallop Patinopecten yessoensis larvae
Journal of Experimental Marine Biology and Ecology, 1988Abstract Growth and ingestion rates were determined for Japanese scallop Patinopecten yessoensis larvae reared at temperatures between 10 and 18 °C and fed concentrations of Isochrysis aff. galbana (clone T-ISO) cells between 5 and 30 cells · μl −1 to gain insight into energy balance.

Estrogen effect on the seasonal levels of catecholamines in the scallop Patinopecten yessoensis
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1989Abstract 1. Seasonal variations of catecholamine levels in the various tissues of Patinopecten yessoensis and the effect of in vivo administration of estradiol-17β (E2) on those levels were investigated using high performance liquid chromatography (HPLC). 2.

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2003
An aminopeptidase was isolated from the mid-gut gland of Patinopecten yessoensis. The enzyme was purified from an acetone-dried preparation by extracting, ammonium sulfate precipitation, Hi-Load Q column chromatography, isoelectric focusing, and POROS HP2 and HQ column chromatography. The molecular weight of the enzyme was estimated to be 61 kDa by SDS-
