this guide to the identification of iranian freshwater snails has been prepared with aim of helping individuals involved in field work, but who have had no specialized training in taxonomy to differentiate snail specimens which they collect to certain groups by means of simple identification key. the guide pays special attention to the principal snail groups which transmit human schistosomiasis...

Abstract We find an unifying approach to the analytic representation of domain bounded by a generalized Pascal snail. Special cases as snail, Both leminiscate, conchoid Sluze and disc are included. The behaviour functions related snail is studied.

snail is one of the worst causes of food allergy. thus, the aim of this study was to identify the major and minor allergens of the local marine snail ( cerithidea obtusa ) and subsequently to investigate the impacts of heat treatment on the ige-binding activity of snail allergens. proteins from raw and heat-treated snails (boiled, roasted and fried) were extracted and then resolved by sodium do...

objective: an experiment was conducted to investigate the effects of citrus brown snail powder as a source of calcium on growth performance, tibia characteristics, immune response and blood metabolites in broiler chickens.  methods: one hundred and eighty 1-day old chicks were randomly distributed into four treatments, each of which had three replicates. each replicate contains 15 chicks. the t...

PURPOSE There are few molecular markers known to predict upper urinary tract urothelial carcinomas (UTUC) prognosis. Snail, which contributes to epithelial-mesenchymal transition (EMT), has been documented in cancer progression, but not clear yet in UTUC. We therefore addressed the expression and biological significance of Snail in UTUC. EXPERIMENTAL DESIGN To elucidate the biological signifi...

BACKGROUND Snail intermediate hosts play active roles in the transmission of snail-borne trematode infections in Africa. A good knowledge of snail-borne diseases epidemiology particularly snail intermediate host populations would provide the necessary impetus to complementing existing control strategy. MAIN BODY This review highlights the importance of molecular approaches in differentiating ...

Two snail species belonging to genus Lymnaea, L.auricularia and L.gedrosiana, were collected from 6 different districts of Shadegan area of Khoozestan. Eight percent of the total collections of the snails revealed the occurrence of larva in them. The prevalence of larva within the snails varied in different districts may be due to different geoclimatic conditions and availability of fresh water...

BACKGROUND Epithelial to mesenchymal transition (EMT) is a complex and dynamic molecular event in lung cancer metastasis that has not yet been thoroughly investigated. EMT transcriptional factors, such as Snail, play a central role in regulation of the EMT process. In this study, we sought to identify an association between p300 and Snail in lung cancer, as well as the engagement of p300 in Sna...

Though prey use a variety of information sources to assess predation risk, evolutionary cohistory with a predator could constrain information use, and nonnative prey might fail to recognize risk from a novel predator. Nonnative prey might instead use generalized risk assessment, relying on general alarm signals from injured conspecifics rather than cues from predators. I tested the influence of...
