Dopamine, noradrenaline, octopamine and tyrosine-hydroxylase in the gastropod Helix pomatia.

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1975
Abstract Sensitive radiochemical procedures were used to measure the dopamine, noradrenaline, octopamine and tyrosine-hydroxylase content in nervous and other tissues in the snail Helix pomatia . 2. The nervous tissue contained higher amounts of dopamine than either noradrenaline or octopamine. Moreover the dopamine content in the different nervous

Histaminergic neurons in the central and peripheral nervous system of gastropods (Helix, Lymnaea): An immunocytochemical, biochemical, and electrophysiological approach

Journal of Comparative Neurology, 2004
AbstractDistribution, chemical‐neuroanatomy, concentration, and uptake‐release properties of histamine (HA)‐containing neurons and the possible physiological effects of HA in the central and peripheral nervous system of the pulmonate snails,Helix pomatiaandLymnaea stagnalis, are described.

Pigment-dispersing hormone-like immunoreactive neurons in the central nervous system of the gastropods, Helix pomatia and Lymnaea stagnalis

Cell and Tissue Research, 1999
By using an antiserum raised against a crustacean beta-pigment-dispersing hormone (PDH), the distribution and chemical neuroanatomy of PDH-like immunoreactive neurons was investigated in the central nervous system of the gastropod snails, Helix pomatia and Lymnaea stagnalis.

Contamination of terrestrial gastropods, Helix aspersa maxima, with 137Cs, 85Sr, 133Ba and 123mTe by direct, trophic and combined pathways

Journal of Environmental Radioactivity, 2006
(137)Cs, (85)Sr, (133)Ba and (123m)Te contaminations of terrestrial gastropods, Helix aspersa maxima, by direct deposition, labelled food ingestion or combined (trophic and direct pathways) exposure were carried out under laboratory conditions. The aim of this study was to compare the three contamination pathways: direct, trophic and combined, in terms

Mytilus inhibitory peptides (MIP) in the central and peripheral nervous system of the pulmonate gastropods, Lymnaea stagnalis and Helix pomatia : distribution and physiological actions

Cell and Tissue Research, 2000
The distribution and neuroanatomy of Mytilus inhibitory peptides (MIP)-containing neurons in the central nervous system and their innervation pattern in the peripheral nervous system of the pulmonate snail species, Lymnaea stagnalis and Helix pomatia, have been investigated immunocytochemically, by applying an antibody raised to GSPMFVamide.

Experiments with the Isolated Heart of the Gastropod Helix Pomatia in an Artificial Pericardium

Journal of Experimental Biology, 1972
ABSTRACT Isolated hearts of Helix pomatia could be maintained for 3–4 days at 19 °C in physiological saline. Co-ordination was soon lost, but irregular twitches could be observed for up to 115 h. A perfusion apparatus was designed which supplied a simulated venous return pressure of 8 cm saline and enabled in vitro survival of ...

Enkephalin-like immunoreactive neurons in the central nervous system of gastropods (Helix pomatia, Lymnaea stagnalis, Aplysia californica): a comparative immunocytochemical study [PDF]

Cell and Tissue Research, 1993
The distribution and morphology of met-enkephalin-like immunoreactive (MetLI) and leu-enkephalin-like immunoreactive (LeuLI) neurons were investigated in the central nervous system of three gastropod species, Helix pomatia, Lymnaea stagnalis and Aplysia californica.

A stable oxygen isotope record of weather-timescale variability in the Eocene greenhouse world, using the giant marine gastropod Campanile giganteum

, 2021
Instrumental climate data are only available for the last few hundred years. To extend this record back in time, climate proxies are used. However, on the geological timescale, the temporal resolution of most paleoclimate records does not provide ...

[Plasticity of stastocyst inertial mass in terraneous gastropods helix lucorum and pomatias rivulare in altering gravitational field (microgravity, hypergravity)].

Aviakosmicheskaia i ekologicheskaia meditsina = Aerospace and environmental medicine, 2012
Light and scanning electron microscopy was used to study the morphological parameters and ultrastructure of Helix lucorum statocysts and statoliths in Pomatias rivulare statocysts after 56, 93 and 110-day exposure to microgravity aboard the ISS. Increased gravity was simulated by 30-d centrifugation at 6 g. On the first day of recovery, many statoconia
