Regulation of Na,K-ATPase biosynthesis in developing Artemia salina.

Regulation of NaK-ATPase Activity by Neurotransmitters

The hitherto unknown NT-regulated mechanism of NaK-ATPase localized in the nerve ending membranes is found. The mechanism certainly has a functional significance and must be involved in the regulation – modulation of chemical synaptic transmission. On the other hand , the availability of the discovered specific protein, regulators (SFa and SFi) of synaptic origin, makes it possible to consider ...

The Osmotic and Ionic Regulation of Artemia Salina

On the metabolism of carotenoids in the crustacean Artemia salina.

Die Zusammensetzung und der Stoffwechsel der Carotinoide in adulten Exemplaren von Artemia salina wurden untersucht. Unabhängig von der Fütterung mit carotinoidfreier Hefe, mit an Oxicarotinoiden reicher Nahrung oder mit Oxocarotinoid-haltigen Algen lassen sich als Hauptpigmente Canthaxanthin (4.4'-Dioxo-/?-carotin) und Echinenon (4-Oxo-/?-carotin) nachweisen. Daneben wur­ den in einer Artemia-...

The Survival of Artemia Salina (l.) in Various Media

The Mechanism of Osmotic Regulation in Artemia Salina (l.): the Physiology of the Branchiae

INTRODUCTION In a previous paper (Croghan, 19586) the very great osmo-regulating ability of Artemia has been described. It is clear that in concentrated media the animal must have very well-developed active mechanisms both for excreting NaCl and for taking up water to compensate for the passive movements of these substances into and out of the animal. The staining of localized parts of Crustace...
