An ancient FMRFamide-related peptide–receptor pair induces defence behaviour in a brachiopod larva
Animal behaviour often comprises spatially separated sub-reactions and even ciliated larvae are able to coordinate sub-reactions of complex behaviours (metamorphosis, feeding). How these sub-reactions are coordinated is currently not well understood. Neuropeptides are potential candidates for triggering larval behaviour. However, although their immunoreactivity has been widely analysed, their f...
متن کاملAn ancient FMRFamide-related peptide-receptor pair induces defense behavior in a brachiopod larva
Animals show different behaviors that can consist of various spatially or temporally separated subreactions. Even less complex organisms, like ciliated larvae that display important behaviors (e.g. metamorphosis, defense, feeding), need to coordinate coherent sub-reactions with their simple nervous system. These behaviors can be triggered by neuropeptides, which are short signaling peptides. De...
متن کاملCutaneous Larva Migrans: A case report
Cutaneous larva migrans is a self-limited cutaneous eruption caused by larva of roundworms that do not normally parasitize humans. Ankylostoma brazielensis, the dog and cat hookworm, is the most common agent. The disease is found in tropical and subtropical regions and may be seen in travelers from these regions. We report a case of a 37-year-old Iranian man who had cutaneous larva migrans afte...
متن کاملVisceral Larva Migrans
There are many causes of persistent eosinophilia in children, but Perlingiero and Gyorgy (1947) described a case in which there was also hepatic enlargement, anaemia and fever. Two years later Zuelzer and Apt (1949) described eight similar cases and suggested that they formed a definite syndrome. Since then several more have been reported and it has been shown that this syndrome is frequently c...
متن کاملBaylisascaris larva migrans.
Baylisascaris procyonis is a roundworm of the raccoon found primarily in North America but also known to occur in other parts of the world including South America, Europe, and Japan. Migration of the larvae of this parasite is recognized as a cause of clinical neural larva migrans (NLM) in humans, primarily children. It is manifested as meningoencephalitis associated with marked eosinophilia of...
