Coelomocytes in the Holothuroidea are traditionally identified according to their morphology through light, fluorescence, or electron microscopy. Former studies have typically used only one method, with few works combining two more approaches. Studies using cytocentrifugation study these cells scarcer. Thus, for first time, an integrative approach was compare coelomocytes Holothuroidea. This co...

CHEMICAL COMPOSITION AND PHOTOPROTECTIVE ANTIRADICAL ACTIVITIES OF THE BRANCHES Platonia insignis (CLUSIACEAE). The chemical study of the branches enabled isolation biflavonoid morelloflavone and identification, by mass spectrometry, over 14 polyphenols, including seven biflavonoids three derivatives, two benzophenones, one xanthone. in vitro biological tests solar photoprotection antiradical a...

Holothuria arguinensis, mammata and forskali are three common sea cucumber species found in the NE Atlantic, traded international markets susceptible to capture. Allometric relationships reveal if scaling between biometric characters proportional with growth, being a useful tool understand growth strategies. of were estimated compared them populations from different regions. These allometric re...

Sea cucumbers are the most important medicinal group among echinoderms. The presence of a wide range of natural bioactive compounds from sea cucumbers has been confirmed in many studies. This study was aimed to evaluate the antibacterial activities of ethanol, methanol and acetone extracts from sea cucumber Holothuria parva. Sea cucumber were collected during low tide from Ola village, Bushehr,...

At least 95 species of Pamphagidae belonging to 17 genera are known in North Africa. Taxonomic status is fairly known, with some exception, mainly due to scarcity of available specimens of some genera in museums and collections. In this paper, the author proposes a new key to genera and reports the annotated list of all the known species, based on specimens examined in different European museum...
