A novel G-protein-coupled receptor (GRL106) resembling neuropeptide Y and tachykinin receptors was cloned from the mollusc Lymnaea stagnalis. Application of a peptide extract from the Lymnaea brain to Xenopus oocytes expressing GRL106 activated a calcium-dependent chloride channel. Using this response as a bioassay, we purified the ligand for GRL106, Lymnaea cardioexcitatory peptide (LyCEP), an...

The present work aimed at studying the effect of Ambrosia maritima (Damsissa) on the viability of Lymnaea snails. Lymnaea snails used in these trials were acclimatized to laboratory conditions before use in the toxicity test. The snails were exposed to various concentrations (100-3000 mg/l) of dry powdered Damsissa, Ambrosia maritima was lethal to Lymnaea snails at concentration of 3000 mg/L af...

the present study was conducted to investigate the prevalence of developmental stages of fasciola gigantica infection in lymnaea snails and their populations in sylhet region of bangladesh. a total of 1865 lymnaea snails were collected and examined, of which 56 (3%) were found to having infected with developmental stages of fasciola gigantica. only 4.08% infected of 515 snails were collected fr...

The pond snail Lymnaea stagnalis is among several mollusc species that have been well investigated due to the simplicity of their nervous systems and large identifiable neurons. Nonetheless, despite the continued attention given to the physiological characteristics of its nervous system, the genetic information of the Lymnaea central nervous system (CNS) has not yet been fully explored. The abs...

Neuropeptides are known to be important signaling molecules in several neural systems of the pond snail Lymnaea stagnalis. Although the functions of these peptides have been studied in many neurons, the nature of the postsynaptic signal transduction is mainly unknown. The cloning and characterization of neuropeptide receptors in Lymnaea thus would be very valuable in further elucidating peptide...

background: ionizing radiation induces the production of reactive oxygen species (ros), which play an important causative role in cell death. the aim of this study was to investigate the protective effects of sulfated derivatives of neutral polysaccharides extracted from auricularia auricular (snaap). materials and methods: whole blood samples from healthy donors treated with snaap at different...

interacting neuronal networks make adaptive behavioral decisions. Further new avenues opened up by recent work on Lymnaea may lead to an understanding of how learning and homeostatic processes interact, to the building of sophisticated computer models of functional connectivity and interacting networks, and even to the development of applications to artificial complex systems. At a different le...

The ability of several subtropical echinoderm larvae to absorb large, dissolved organic molecules was assessed by exposing them to FITC-BSA and Ferritin. We tested shallow water auricularia and pentacula from unknown species, plutei from the shallow water Tripneustes sp. and deep water Cidaris blakei blastula and gastrula. Once larvae had been exposed for several hours, FITC-BSA treated larvae ...

This study was conducted to investigate the life history, morphology, and maturation of larval stages and adult worms of Fasciola gigantica in experimental mice. Lymnaea auricularia rubiginosa was used as the intermediate host, and Oryza sativa was used for encystment of the metacercariae, while Mus musculus was used as the definitive host for maturation study. Fresh eggs from the gall bladder ...

Some unusual specimens of the wood-inhabiting fungus Auricularia auricula-judae have been studied using morphological and molecular methods. As expected from external features, we describe a new species cerrina sp. nov. Sequencing ITS region confirms differences other Auricularia, preliminary phylogenetic analysis is presented. characterized by blackish fruitbodies in fresh conditions with comb...
