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...

Herbivorous marine snails like Littorina species are known to possess alginate lyases in their digestive tracts. The Littorina enzymes have been identified as endolytic polymannuronate (poly(M)) lyases (EC 4.2.2.3); however, it is still unclear which polysaccharide-lyase family (PL) the Littorina enzymes belong to, since no complete primary structure of Littorina enzymes has been determined. Th...

UNLABELLED Pancreatic ductal adenocarcinoma (PDAC) is associated with a pronounced fibro-inflammatory stromal reaction that contributes to tumor progression. A critical step in invasion and metastasis is the epithelial-to-mesenchymal transition (EMT), which can be regulated by the Snail family of transcription factors. Overexpression of Snail (Snai1) and mutant Kras(G12D) in the pancreas of tra...

limited studies have been made on the cercariae from freshwater snails in iran. this study was conducted to determine the cercariae fauna of bellamya (viviparus) bengalensis and evaluation of their zoonotic importance in khuzestan province, south-west of iran. for this purpose, 1143 bellamya snails were collected from ahoudasht region in central areas of the province during 2002-2003. bellamya ...

BACKGROUND Snail is a key regulator of epithelial-mesenchymal transition (EMT) in cancer. However, the regulatory role and underlying mechanisms of Snail in gastric cancer metabolism are unknown. In this study, we characterized the regulation of aerobic glycolysis by Snail in gastric cancer. METHODS The impact of Snail on glucose metabolism was studied in vitro. Combining maximum standardized...

Group or population level self-organised systems comprise many individuals displaying group-level emergent properties. Current theory indicates that individual-level behaviours have an effect on the final group-level behaviour; that is, self-organised systems are sensitive to small changes in individual behaviour. Here we examine a self-organised behaviour in relation to environmentally-driven ...

Background: The flukes liver is common parasite of human and livestock that has effect on loss of economic. The human is final host parasites that infected of flukes liver. The fluke is a significant human health problem and damage liver of human. Materials and methods: This cross sectional study was performed in the livestock of slaughtered in the slaughter house in Khormabad and 2912 liv...
