Molecular Detection and Genetic Analysis of Betanodaviruses in Bivalve Mollusks

Journal of Biotechnology, 2010
Betanodaviruses are small ssRNA viruses responsible of Viral Nervous Necrosis in marine fishes worldwide. In this study, we examined bivalve mollusks for the presence of Betanodavirus and genetically analyzed the detected viruses to find out whether these animals could be a source of genetically closely related Betanodaviruses transmissible ...

Succinate and lactate oxidoreductases of bivalve mollusks

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1975
Abstract 1. 1. Succinic acid is a major end product of anaerobic glycolysis in mollusks, and lactic acid is a minor product. On the hypothesis that production of these acids is partially controlled by properties of the enzymes catalyzing the final step in each pathway, extracts of the adductor muscle were prepared and used in oxidoreductase ...

Heavy Metals in Bivalve Mollusks

2017
This chapter reviews the concentrations of several major metal contaminants in bivalve mollusks collected from different regions of the world. Bivalve mollusks considered in this chapter include oysters, mussels, scallops, and clams, all of which are the major seafood products in the world.

Microplastics in global bivalve mollusks: A call for protocol standardization

Journal of Hazardous Materials, 2022
A growing body of evidence shows that microplastic pollution is ubiquitous in bivalve mollusks globally and is of particular concern due to its potential impact on human health. However, non-standardized sampling, processing, and analytical techniques increased the difficulty of direct comparisons among existing studies.

Bivalve Mollusks: Fluid Dynamics of Burrowing

Science, 1966
When bivalves burrow into soft substrates the foot is first extended and then dilated to obtain a firm anchorage before retraction pulls the shell downward. Pedal dilation is principally caused by adduction of the valves. The hinged shell functions as a hydraulic machine in which the strength of the adductor muscles is transferred to the distal part of

Bivalve Mollusks: Control of Microbiological Contaminants

BioScience, 1982
Historically, shellfish made a significant contribution to the American diet. Early inhabitants found abundant supplies of bivalve mollusks that could easily be harvested year-round. Shellfish, along with an ample supply of fish, provided high quality protein with little effort or cost to the consumer.

Exploring Satellite DNAs: Specificities of Bivalve Mollusks Genomes

2021
Noncoding DNA sequences repeated in tandem or satellite DNAs make an integral part of every eukaryotic genome. Development and application of new methodological approaches through time enabled gradual improvement in understanding of structural and functional roles of these sequences, early misconsidered as "junk DNA".

Permian bivalve mollusks of Northeast Asia

Journal of Asian Earth Sciences, 2006
Abstract Bivalve mollusks are very important in the Permian biota of Northeast Asia. During the Permian the bivalves had different distribution patterns both in space and time, and their occurrence was governed by many factors related to water depth and geodynamic conditions. In Northeast Asia there were two main bivalve paleocommunities, shallow and

Doctors in the Kitchen

New England Journal of Medicine, 1981
The use of raw or hurriedly steamed shellfish is recognized as a vehicle for the transmission of typhoid fever and Type A viral hepatitis.1 Steaming contaminated clams for five minutes or less is not sufficient for them to reach an internal temperature suitable for sterilization.2 Steaming for 15 minutes does suffice for sterilization, but this method ...

[Gonad innervation in bivalve mollusks].

Arkhiv anatomii, gistologii i embriologii, 1983
In marine Lamellibranchia--Patinopecten yessoensis (Jay) and Crenomytilus grayanus (Dunker)--neural cells, small ganglia and neural fibres have been revealed in the gonad wall. The sensitive and effector parts are presented by rather variable morphological formations.
