Nutrient effects of broodstocks on the larvae in Patinopecten yessoensis

Chinese Journal of Oceanology and Limnology, 2015
Patinopecten yessoensis is a commercial valuable species. This study deals with the effect of nutrient effects of the broodstock (mainly ovaries) on the larvae. Concentrations of total carbohydrate, total protein and total lipid in the gonads of P. yessoensis from three Hatcheries (Hatchery 1, Hatchery 2, and Hatchery 3) were determined before and ...

Isolation and Characterization of Lectin from the Scallop Patinopecten yessoensis

Chemistry of Natural Compounds, 2017
Lectin (PYL) of molecular mass 17,154.5 Da that exhibited Gal/GalNAc-specificity was isolated from the scallop Patinopecten yessoensis. The lectin was completely inactivated by heating to 60°C for 30 min, exhibited the greatest activity at pH 5–9, and was metal-independent.

Potential GnRH and steroidogenesis pathways in the scallop Patinopecten yessoensis

The Journal of Steroid Biochemistry and Molecular Biology, 2020
Gonadotropin-releasing hormone (GnRH) controls synthesis of sex steroid hormones through hypothalamic-pituitary-gonadal (HPG) axis in vertebrates. But in mollusks, research on GnRH and steroidogenesis pathways is still limited. In this study, we first identified two gonadotropin receptor like genes (LGR and LGR5L) and four steroidogenesis-related genes

Fucosylated heparan sulfate from the midgut gland of Patinopecten yessoensis

Carbohydrate Polymers, 2023
The structural and functional relationships of glycosaminoglycans (GAGs) derived from marine organisms have been investigated, suggesting that marine invertebrates, particularly Bivalvia, are abundant sources of highly sulfated or branched GAGs. In this study, we identified a novel fucosylated heparan sulfate (Fuc-HS) from the midgut gland of the ...

A Molecular Cytogenetic Map of Scallop (Patinopecten yessoensis)

Marine Biotechnology, 2019
To consolidate the genetic, physical, and cytogenetic maps of scallop (Patinopecten yessoensis), we constructed a molecular cytogenetic map by localizing 84 fosmid clones that contain different SNP markers from 19 linkage groups (LGs) using fluorescence in situ hybridization (FISH).

Polar Steroids from the Marine Scallop Patinopecten yessoensis

Journal of Natural Products, 1988
Eight polyhydroxylated sterols, seven of them novel, have been isolated from the hepatopancreas of the scallop Patinopecten yessoensis. Compounds 1−7 possessed the same Δ 7 -3β,5α,6β-triol nucleus but differed in the side chains. One very minor component 8 had an additional hydroxyl group at C-9α. Their structures were deduced from spectral data and by

Developmental dynamics of myogenesis in Yesso Scallop Patinopecten yessoensis

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2019
The development of bivalves has been extensively studied over the last 150 years. Despite this, the developmental dynamics of myogenesis in bivalves remains largely unknown, particularly at the early developmental stages. In the present study, we investigate the characteristics of muscle development of Yesso scallop Patinopecten yessoensis by ...

Adenosine deaminase in the adductor muscle of the scallop, Patinopecten yessoensis

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1991
1. The scallop enzyme was separated by DE52 ion-exchange chromatography into two forms with the same mol. wt of 38,000 and similar characteristics. 2. The enzyme was inactivated in the absence of dithiothreitol and complete reactivation was achieved by adding the agent within a critical storage period. 3. The apparent values of pKm and Vmax sensitively

Involvement of prostaglandins in the spawning of the scallop, Patinopecten yessoensis

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1989
Abstract 1. A high performance liquid chromatography (HPLC) using 9-anthryldiazomethane (ADAM) as a fluorescent reagent was employed to detemine the levels of endogenous prostaglandins (PGs) in the central nervous system, gonad, gill and hemolymph of the scallop, and the authors have also verified the involvement of PGs during spawning induced by u.v.

Adsorption of minerals on the isolated mantle of Patinopecten yessoensis

Fisheries Science, 2002
: The isolated mantle of scallop (Patinopecten yessoensis) was shown to adsorb minerals (Zn, Ca, Mg, Fe, Cu, Ni and Co) to more than 1% upon treatment with mineral solution. The amounts of adsorbed Zn, Ca and Mg were 44.3, 47.4 and 15.5 mg/g dry weight, when the mantle was treated with 5% ZnSO4, CaCl2 and MgSO4 solutions at room temperature ...
