Helicometrina nimia Linton, 1910 (Digenea: Opecoelidae) in dusky grouper Epinephelus marginatus (Lowe, 1834) (Teleostei: Serranidae) from southeastern Brazil.
Helicometrina nimia (Opecoelidae) is a digenean with wide distribution. Fish families most commonly used as hosts for H. nimia are Serranidae, Pomodasydae, Scorpaenidae and Clinidae. In the present study, a new host and a new host locality are presented for the species. A description of the studied specimens, besides comments concerning its taxonomic status and biometrically compared tables of ...
متن کاملAristotle revisited: the function of pyloric caeca in fish.
The function of the pyloric caeca of fish has been uncertain since their detailed description in 345 B.C. by Aristotle. He suggested three hypotheses about their function: "to store up the food," "putrify it up," and "concoct it" (i.e., storage, fermentation, and digestion). Our results for trout, cod, largemouth bass, and striped bass support the third but not the first or second of Aristotle'...
متن کاملL-proline Transport Systems of Starfish Pyloric Caeca
Purified brush-border membrane vesicles (BBMV) of starfish [Pycnopodia helianthoides (Brandt)] pyloric caecal epithelium were prepared by magnesium precipitation in order to characterize the possible role of this organ in amino acid transport. L-[H]proline uptake by these vesicles was Na-dependent and greater at pH7.5 than at pH5.5. L-Pipecolate was a competitive inhibitor of L-proline influx i...
متن کاملDietary phosphorus-responsive genes in the intestine, pyloric caeca and kidney of rainbow trout
Identification of phosphorus (P)-responsive genes is important in diagnosing the adequacy of dietary P intake well before clinical symptoms arise. The mRNA abundance of selected genes was determined in the intestine, pyloric caeca, and kidney of rainbow trout fed low-P (LP) or sufficient-P (SP) diet for 2, 5 and 20d. The LP/SP ratio of mRNA abundance was used to evaluate the difference in gene ...
متن کاملImmunohistochemical study of the endocrine cells in the stomach and pyloric caeca of the mountain trout, Salmo trutta macrostigma
The endocrine cells of Salmo trutta macrostigma stomach and pyloric caeca have been investigated using immunohistochemical techniques. 8 antisera were tested and 6 of them were detected in the endocrine cells serotonin, somatostatin, substance P, galanin, CCK and neuropeptide Y. These immunoreactive cells are described for the first time in the stomach and pyloric caeaca of Salmo trut...
