Cell & Tissue Research, 1994 The distribution of neuropeptide F (NPF) immunoreactivity in the snail, Helix aspersa, has been demonstrated by immunocytochemistry using 2 region-specific antisera. One, designated NPF3, was raised against a synthetic N-terminal fragment of Helix aspersa NPF; the other, designated PP221, was raised against the C-terminal hexapeptide amide of mammalian

General and Comparative Endocrinology, 2003 Daily patterns of melatonin and 5-methoxytryptophol (5-ML) concentrations and of aryl alkylamine N-acetyltransferase (AA-NAT) and hydroxyindole-O-methyltransferase (HIOMT) activities have been measured in the cerebroid ganglions, visceral ganglions, and ocular tentacles of the gastropod mollusc Helix aspersa maxima.

Environmental Toxicology and Chemistry, 2004 Abstract The two function-specific metallothionein (MT) isoforms characterized from the midgut gland and mantle tissue of Helix pomatia differ substantially in their metal-binding preferences, as well as molecular and biochemical features.

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1972 Abstract 1. 1. An analysis of the tissues in the snail Helix pomatia showed that per 100 μg wet weight of tissue the brain contained 1·4 μ g phospholipid, the heart 0·87 μ g, the liver 0·6 μ g and the kidney 0·44 μ g. 2. 2. The use of a sensitive microprocedure revealed the phospholipid composition of the brain to be: phosphoinositides ...

Tissue and Cell, 1994 Neuropeptide F (NPF)-immunoreactivity has been localized by electron microscopy in the central nervous system of the gastropod mollusc, Helix aspersa using a region-specific antiserum in conjunction with post-embedding immunogold labelling. The specific antiserum employed, designated NPF3, was raised to a synthetic N-terminal fragment of H. aspersa NPF.

Comparative Biochemistry and Physiology Part A: Physiology, 1988 Abstract 1. 1. The brown garden snail Helix aspersa Muller, young or adult, takes in and absorbs water orally through its digestive system. 2. 2. During the first month, Helix aspersa is able to absorb 70% of its total weight, in water, daily.

Annexin-immunoreactive proteins in the nervous system and eye of the gastropods, Aplysia and Helix
Brain Research, 1997 We studied the distribution of annexin I- and annexin V-like proteins in the eye and central nervous system of the snails, Aplysia californica and Helix pomatia by immunocytochemistry. Annexin I-immunoreactive material in Aplysia californica was localized in sensory and corneal cells of the eye and in distinct neurons of the cerebral, buccal, and ...
