AF2, an Ascaris neuropeptide: Isolation, sequence, and bioactivity
A FMRFamide-like neuropeptide, KHEYLRFamide (Lys-His-Glu-Tyr-Leu-Arg-Phe-amide; AF2) was isolated from a head extract of the nematode Ascaris suum by using a three-step HPLC separation. In a dorsalExpand

Eight novel FMRFamide-like neuropeptides isolated from the nematode Ascaris suum
Eight FMRFamide-like neuropeptides were isolated from an extract of heads and tails from the nematode Ascaris suum using seven steps of HPLC. The peptides ranged in size from 8 to 14 amino acidExpand

Structure and physiological activity of the motoneurons of the nematode Ascaris.
The nervous system of the nematode worm Ascaris contains about 250 nerve cells; of these, the motoneurons consist of five segmental sets, each containing 11 cells. Morphologically, the motoneuronsExpand

Neural control of behaviour in Ascaris
Abstract The Ascaris motor nervous system contains about 90 motorneurons and interneurons. In order to understand its function, our strategy has been to start with an extensive morphological analysisExpand

Mass spectrometric map of neuropeptide expression in Ascaris suum
A mass spectrometric method was used for the localization and sequence characterization of peptides in the nervous system of the parasitic nematode Ascaris suum. Mass spectrometric techniquesExpand

Motor behavior and motor nervous system function in the nematode Ascaris suum.
Ascaris suum has a nervous system that is very simple both numerically and morphologically. It comprises only 298 neurons almost all of which are extremely simple in shape. Extensive anatomicalExpand
