NUCLEOTIDES OF THE PACIFIC OYSTER CRASSOSTREA GIGAS (THUNBERG)

Canadian Journal of Biochemistry, 1964
The nucleotides of the Pacific oyster Crassostrea gigas (Thunberg) have been fractionated by chromatography on diethylaminoethyl cellulose and characterized by their ultraviolet absorption and paper chromatographic properties. Major components were adenosine-5′ phosphate, adenosine-5′ diphosphate, and adenosine-5′ triphosphate.

Xenobiotic biotransformation in the pacific oyster (Crassostrea gigas)

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1989
1. Oyster visceral mass and gill tissues possessed measurable flavin-containing monooxygenase (FMO) activity. 2. FMO activity was confirmed in visceral mass microsomes by oxygen uptake experiments utilizing various nitrogen and sulfur-containing chemicals along with measurement of N,N-dimethylaniline (DMA) N-oxidase and methimazole oxidation activities.

The granulocytes are the main immunocompetent hemocytes in Crassostrea gigas

Developmental & Comparative Immunology, 2017
Hemocytes comprise diverse cell types with morphological and functional heterogeneity and play indispensable roles in immunological homeostasis of invertebrates. The morphological classification of different hemocytes in mollusk has been studied since the 1970's, yet the involvement of the different sub-populations in immune functions is far from clear.

Antihypertensive activity of polysaccharide from Crassostrea gigas

International Journal of Biological Macromolecules, 2016
Water-soluble polysaccharide was extracted from Crassostrea gigas by hydrolysis with flavourzyme and filtered, ultrafiltered and precipitated using absolute ethanol. Sugar composition analysis performed on the C. gigas polysaccharide (CGP) by high performance liquid chromatography indicated that it was comprised primarily of glucose, and its molecular ...

A cDNA Microarray for Crassostrea virginica and C. gigas

Marine Biotechnology, 2007
The eastern oyster, Crassostrea virginica, and the Pacific oyster, C. gigas, are species of global economic significance as well as important components of estuarine ecosystems and models for genetic and environmental studies. To enhance the molecular tools available for oyster research, an international group of collaborators has constructed a 27,496 ...

Avoiding polyspermy in oyster (Crassostrea gigas)

Aquaculture, 1988
Abstract Polyspermy was assayed by counting sperm pronuclei in orcein-stained eggs of Crassostrea gigas with ordinary light microscopy. When oocytes were inseminated within 15 min of their mechanical removal from the ovary, they became highly polyspermic, for example, 54% polyspermy with external sperm oocyte ratios as low as 30.

The immunological capacity in the larvae of Pacific oyster Crassostrea gigas

Fish & Shellfish Immunology, 2016
As the immune system has not fully developed during early developmental stages, bivalve larvae are more susceptible for pathogens, which frequently leads to the significant mortality in hatcheries. In the present study, the development of immune system and its response against bacteria challenge were investigated in order to characterize the repertoire

Stress-induced immune changes in the oyster Crassostrea gigas

Developmental & Comparative Immunology, 2002
Information concerning the effect of stress on invertebrate immune functions are scarce. The present study investigated the consequences of a 15-min mechanical disturbance on immune parameters in oysters Crassostrea gigas. As indicated by noradrenaline and dopamine measurements, the mechanical disturbance caused a transient state of stress in oysters ...

Efficacy of Vibrio parahaemolyticus depuration in oysters (Crassostrea gigas)

Food Microbiology, 2019
This study investigated the influences of seawater to oyster ratio on depuration for decontaminating V. parahaemolyticus in raw oysters with a goal of identifying the proper ratio of oyster to seawater capable of improving the efficacy of the depuration process.

Genomics of the Pacific Oyster Crassostrea gigas

2003
Mapping and sequencing of the biologically significant genes in the oyster genome will provide an invaluable information to the basic fishery sciences as well as the development of new biotechnologies necessary to improve the oyster farming. Thus, we initiated the genomic analysis of the Pacific oyster C.
