Recording of the mollusc osphardium nerve activity revealed the osphardium sensitivity to hyperosmotic pressure, sodium chloride, and aminoacidosis. The osphardium was found to detect quality of the water where the animals were kept. Pont snail osphradium preserves ancestors' multisensority which unites perception of different chemical and physical signals. Patch-clamp method revealed membrane currents in certain ganglia and receptor cells which are sensitive to Na+ and L-aspartate increase in the solution around the osphardium. Inward components of these currents are, probably, of the sodium and/or calcium nature, whereas the outward components--of the potassium one. 相似文献

Indicators are helpful tools for land use management; especially in the context of sustainable urban development, they are indispensable information bases for decision making, communication, and awareness rising. For Santiago de Chile, like many other large and dynamic cities, a high complexity of geographical conditions, social and land use pattern, diverging interests, and a high velocity of development are characteristic. In this situation, the Risk Habitat Megacity (RHM) initiative seeks to support local and regional authorities in elaborating indicators applicable in land use and flood risk management.In this article, the indicator approach of the Land Use Management group within the RHM initiative is presented. Based on the analysis of characteristics of and demands on sustainability indicators, existing indicator sets for Santiago de Chile are analysed. Thereafter, the indicator set for sustainable land use management in Santiago de Chile is presented. It was elaborated in a combined bottom–up and top–down approach in discussion with Chilean scientists and stakeholders in order to guarantee its relevancy to practice. The analysis of the already existing indicators in Santiago de Chile shows that the newly developed toolset forms a valuable and complementary addition, mainly for two reasons: the interdisciplinary nature of the set and its reproducibility. 相似文献

The genus Wrightoporia has been amended to include resupinate to pileate polypores with clamped generative hyphae, dextrinoid skeletal hyphae and small, smooth to ornamented amyloid spores. A key is given to the 7 accepted species and W. cinnamomea and W. cylindrospora are described as new. The combination W. subrutilans (Murr.) Ryv. is proposed. 相似文献

FMRFamide is one of the well-known peptides studied within the phylum Mollusca. It was first isolated from the clam Macrocallista nimbosa during the end of the 1960s. Since then, a number of reports related to FMRFamide have been published from different experimental approaches, revealing that it and its related peptides (FaRPs) are implicated in a variety of physiological processes. As this year is the 30th anniversary since its discovery, this review focuses on diverse findings related to both FMRFamide and FaRPs in the phylum Mollusca. 相似文献

Summary Previous findings have demonstrated the presence of muramic acid and the lack of sialic acid in gastropod glycoconjugates from different tissues. The present study investigated the composition of muramyl derivatives in Mollusca Gastropoda tissue from the foot, mantle and periesophageal ganglia, using HRP-labeled lectins (LTA, UEA I, GSA IB4, GSA II, DBA, SBA, RCA II, WGA, PNA, ConA) and glycosidase digestion (neuraminidase, lysozyme, -l-fucosidase, -N-acetylglucosaminidase, -N-acetylgalactosaminidase). Muramyl derivatives from the tissue examined showed some differences related to the composition of the terminal disaccharides. Indeed, foot and mantle mucocytes exhibited muramic acid in a terminal position, linked to (subterminal) N-acetylgalactosamine, whereas in neuron cells muramic acid was present in an internal position and linked to N-acetylglucosamine. Diversities also occurred between foot and mantle mucocytes with respect to the receptor sugar for penultimate N-acetylgalactosamine. 相似文献
