| germinoma in razor clam ensis arcuatus (jeffreys, 1865) in galicia (nw spain). | germinoma is a gonadal neoplasm originating from progenitor cells in germinal epithelium. over the last four decades it has been diagnosed in several species of marine bivalve molluscs but most consistently in some populations of mercenaria mercenaria and mya arenaria in north america. tissue sections of gonads from ensis arcuatus (family pharidae--superfamily solenacea), collected in ría de vigo (galicia-nw spain), revealed germinoma in both males and females. proliferating, undifferentiated, g ... | 2006 | 16905143 |
| histological survey of symbionts and other conditions in razor clam ensis arcuatus (jeffreys, 1865) (pharidae) of the coast of galicia (nw spain). | symbionts and abnormal conditions of razor clam ensis arcuatus were surveyed in three commercially important natural beds of galician estuaries (nw spain). samples of 15-20 e. arcuatus were collected every 2 months from january 2003 until july 2004 and processed for histological examination. prokaryote-like colonies, renal coccidians, gregarines, trichodina sp. ciliates, haplosporidian-like plasmodia, turbelaria, trematode metacercariae, cestode-like larvae and basophilic inclusion bodies were o ... | 2010 | 20034497 |
| accumulation trends of petroleum hydrocarbons in commercial shellfish from the galician coast (nw spain) affected by the prestige oil spill. | aliphatic and aromatic hydrocarbons were determined in three species of commercial shellfish, namely razor shells (ensis arcuatus and ensis siliqua), goose barnacle (pollicipes cornucopia) and sea urchin (paracentrotus lividus), living in different habitats and exhibiting different feeding behaviors. the samples were collected monthly, from january 2003 to october 2004, in three stations of the galicia coast (nw spain), following the prestige oil spill, with the aim of assessing their response t ... | 2009 | 19150729 |
