This study was designed to test the authors’ hypothesis that dopamine passes from dopamine-synthesizing cells in the brain to the systemic circulation prior to the formation of the blood-brain barrier during ontogenesis. High-performance liquid chromatography studies demonstrated that peripheral blood dopamine levels before formation of the blood-brain(More)
The aim of the present work was to verify the hypothesis that non-dopaminergic neurons expressing individual complementary dopamine synthesis enzymes can perform the co-located synthesis of dopamine. According to this hypothesis, neurons expressing tyrosine hydroxylase use L-tyrosine for the synthesis of L-dihydroxyphenylalanine (L-DOPA), which then enters(More)
This paper describes a new cumacean species, Campylaspis vassilenkoae sp. n., which was found in the northwestern Sea of Japan at 250–1550 m. C. vassilenkoae sp. n. is most similar to C. aperta Lomakina, 1958, but it differs from the latter species in the shape and size of the depression on the carapace, the absence of eye lenses, and a smaller ratio of the(More)
