[Brain lipid biochemistry of the sturgeons Acipenseridae].

Zhurnal evoliutsionnoi biokhimii i fiziologii, 1976
Brain lipids of 4 species of sturgeons-Acipenser güldenstädti, A. stellatus, A. ruthenus and Huso huso-have been investigated. In whole brain homogenates the content of the basic phospholipid families, their fatty acid composition as well as the content of glycosphingolipids-gangliosides, cerebrosides and sulfatides were studied.

Regularities in the Development of Nucleus praeopticus (Np) in Acipenseridae

1978
Early stages in the development of the elements of the peptidergic preoptico-hypophyseal system (PHS), especially those of neurosecretory cells (NSC), have not been studied sufficiently (see YAKOVLEVA, 1974). Only isolated electron-microscopic observations on Teleostei have been reported (FOLLENIUS, 1965).

Olfactory Receptors in Acipenseridae Fish Larvae

1992
Basic aspects of the development of the olfactory system of Acipenseridae occurs during the period between the embryo’s hatching and its period of independent feeding. It was found that actively feeding Acipenseridae larvae have the same types of olfactory receptor cells as observed in adults (Pyatkina, 1976).
