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".

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.

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.

Laboratory Cultivation of Assorted Bivalve Mollusks

1975
Probably no more than two or three dozen of the species of marine bivalves have ever been cultured through their entire life cycle. Larval stages of perhaps fifty additional species have been reared in the laboratory, but juveniles have not been cultured, The life cycles of bivalves in the orders Solemyoidea and Septibranchia are not even known ...

Bivalve Mollusk Burrowing Aided by Discordant Shell Ornamentation

Science, 1969
Oblique and chevron-like ridges on the shell surfaces of certain burrowing bivalve mollusks grip the sediment during shell-rocking movements to aid in sediment penetration. These ridges (characterized by steep dorsal slopes and gentle ventral slopes) have evolved through convergence in several families in association with particular behavioral and ...

[Diseases of bivalve mollusks: risk and prevention].

Revue scientifique et technique (International Office of Epizootics), 1998
The farming of shellfish, based on fishing and rearing in a natural environment, has developed considerably in recent years, particularly as a result of production of spat and juveniles in hatcheries and nurseries. The growing demand for trade in products, facilitated by modern means of transport, has increased the risks of disease spread.
