The duality of teleost gonadotropins
Fish Physiology and Biochemistry, 1989The duality of salmon gonadotropins has been proved by biochemical, biological, and immunological characterization of two chemically distinc gonadotropins. GTH I and GTH II were equipotent in stimulating estradiol production, whereas GTH II appears to be more potent in stimulating maturational steroid synthesis. The ratio of plasma levels and pituitary

Increasing evidences suggest that there is a great degree of similarity in the morphologi- cal and functional organization of immune defences across jawed vertebrates, and lymphocytes are among the most conserved elements. Some peculiarities make lymphocytes unique cells, they contain enzymes (RAGs) able to recombine somatically genome sequences ...

Evolution and Distribution of Teleost myomiRNAs: Functionally Diversified myomiRs in Teleosts
Marine Biotechnology, 2016Myosin heavy chain (MYH) genes belong to a multigene family, and the regulated expression of each member determines the physiological and contractile muscle properties. Among these, MYH6, MYH7, and MYH14 occupy unique positions in the mammalian MYH gene family because of their specific expression in slow/cardiac muscles and the existence of intronic ...

THE available evidence suggests that a calorogenic effect of the thyroid is doubtful in Teleosts. There has been a failure to modify the oxygen consumption, and therefore the heat production, by increasing or decreasing the amount of thyroid hormone available.

Vibration of the Otoliths in a Teleost
2012Fish populations comprise essential parts of marine and freshwater ecosystems as well as being the foundations of considerable human nutrition, industry, and economy. There is growing concern about the possible harmful effects from human-generated sound on fish.

Cytophysiology of the Teleost Pituitary
1971Publisher Summary The teleost pituitary has a special advantage as a subject for endocrine research because in the adenohypophysis the cells of a single type are frequently grouped together. Thus cells can be identified after experimental treatments even though their appearance may have been profoundly altered.

Comparative Biochemistry and Physiology Part A: Physiology, 1972
Abstract 1. 1. The inter-relationships of ions in and between the major body compartments of Perca fluviatilis were studied. 2. 2. These are discussed individually in detail, but in particular Na and Mg were found to be the most tightly regulated of all ions and showed a highly significant inverse relationship in both plasma and cell. 3.

Origin of the Teleost Scale-Pattern and the Development of the Teleost Scale
Nature, 1936ACCORDING to current accounts of scale formation in Teleosts, the scale papillae originate as independent centres of growth, their constituent cells being derived from the immediately underlying dermis. The remarkable regularity of arrangement of the scales in most fishes has always attracted attention and has led Backman1 to suggest that each papilla ...

Survey of the Adrenal Homolog in Teleosts
2003The adrenal homolog of teleosts is not a compact organ as the adrenal glands of most vertebrates but is composed by aminergic chromaffin and interrenal steroidogenic cells located mostly inside the head kidney that, in this taxon, generally has a hematopoietic function.

Puberty is the process by which animals acquire for the first time the ability to reproduce. In teleost fishes, an understanding of the mechanism underlying pubertal development is important not only for basic science but also for aquaculture. In this article, recent progress in several aspects of puberty in teleosts is reviewed; namely, pubertal ...
