This review highlights the similarities between metastatic tumours and schistosomes in particular, and describes the role that proteases may have in the migration, growth, survival and transmission of the different stages of the schistosome life-cycle in the vertebrate host. An elastase-like serine ...
we here report on the diversity of avian schistosomes associated with marine life-cycles usingcox1 and 28S rDNA sequence data. The present study is the first to molecularly elucidate the life-cycle of the first ever described schistosome,O.canaliculata...
The life cycle of Schistosoma is a complex one; it uses freshwater snails as an intermediate host, in which it develops and then moves into humans, which are the definitive host. CDC Schistosomais sexually dimorphic, with males being larger than females. Once a female comes into contact with ...
In association with the evolution of life cycle patterns, our result supports the hypothesis that the most recent common ancestor of the Neodermata giving rise to the Monogenea adopted vertebrate ectoparasitism as its initial life cycle pattern and that the intermediate hosts of the Trematoda (...
The influence of Sister Helen Prejean on the life and work of Jake Heggie as seen in the song cycle The Deepest Desire: Four Meditations on Love. Jake Heggie, American art song and opera composer, began his association with Sister Helen Prejean, CSJ when he composed Dead Man Walking, an...
exhibits an exceptional developmental plasticity in its life cycle characterized by parasitic and free-living generations. We investigated ESP from infective larvae, parasitic females, and free-living stages of the rat parasite Strongyloides ratti, which is genetically very similar to the human pathogen,...
The basic life-cycle of the monogeneans and digeneans are different (Figure 1). Most ectoparasitic monogeneans release infective stages directly into the environment which then infect new hosts (Figure 1A). The digeneans are typically parasites of vertebrates, from which stages are released into th...
O. viverrini has a complex life cycle6, involving snail and fish intermediate hosts, and piscivorous definitive hosts (including humans, dogs or cats). Humans become infected when they consume raw freshwater fish infected with metacercariae (larval stage), after which the juvenile fluke hatches in...
This proposal integrates salient information from the present study (*) and considers published literature. Metastasis-associated protein 1-mediated fibrosis and transformation of cell cycle progress are linked to: transforming growth factor-beta (TGF-beta) and epidermal growth factor receptor (EGFR)-med...
