Hydra is among the most primitive organisms possessing a nervous system and chemosensation for detecting reduced glutathione (GSH) for capturing the prey. The movement of prey organisms causes mechanosensory discharge of the stinging cells called nematocysts from hydra, which are inserted into the prey. The feeding response in hydra, which includes curling of the tentacles to bring the prey tow...
background: cutaneous reactions like pruritus and erythema are common in warm months of the year in bushehr port, persian gulf, iran due to jellyfish envenomation. this study reports isolation of the chrysaora hysoscella nematocysts and evaluating its pharmacological activities during a bloom in 2013. methods: the venom of c. hysoscella captured in jofre area in bushehr port was analyzed. the e...
dispersed genes in different lineages. First, the cluster may have been broken up in organisms with elevated rates of genome evolution, such as C. intestinalis, C. elegans and Drosophila melanogaster. This implies that cluster integrity in other lineages may not be due to selection. Conversely, clusters may have been maintained in some lineages due to selection. This would imply a relaxation of...
Olindias sambaquiensis, known as agua viva, is an endemic hydromedusa that is distributed from latitude 23 degrees to 42 degrees south in the southwestern Atlantic Ocean and is known to cause severe stings. This is the first report of the use of vinegar in disarming O sambaquiensis nematocysts and includes preliminary observations on its use in managing the stings of hydromedusae.
