Aminopeptidase activity is related to the amino acids composition of the food in passerine birds
(PeerJ, 2017-12)
Background. Passerine birds exploit different kinds of feeding habits and they have to face seasonal changes in food availability. Therefore, the composition of the principal nutrient in their food differs from the usual. ...
Dietary modulation of intestinal enzymes of the house sparrow (Passer domesticus): Testing an adaptive hypothesis
(Elsevier Science Inc., 2000-01)
Insectivorous/frugivorous passerine species studied so far lack the ability to modulate intestinal maltase activity, in contrast to galliformes. We tested for dietary modulation of small intestine (SI) enzymes including ...
Trypsin and N-aminopeptidase (APN) activities in the hepatopancreas of an intertidal euryhaline crab: Biochemical characteristics and differential modulation by histamine and salinity
(Elsevier Science Inc, 2017-02-05)
No studies are available about biochemical characteristics and modulation (i.e. by endogenous and/or environmental cues) of trypsin (a key digestive endoprotease) in hepatopancreas of intertidal euryhaline crabs neither ...
Adaptation of intestinal epithelial hydrolysis and absorption of dietary carbohydrate and protein in mammals and birds
(Elsevier Science Inc., 2021-03)
The small intestine of mammals and birds exhibits fascinating variation across taxa, body size, and life history features such as locomotion and diet. In the intestine's brush border membrane (BBM), hydrolases are more ...

Ghrelin and NUCB2/Nesfatin-1 Co-Localization With Digestive Enzymes in the Intestine of Pejerrey (Odontesthes bonariensis)
(Veterinary and Human Toxicology, 2019-06)
Ghrelin (orexigenic) and nesfatin-1 (anorexigenic) are two peptides with opposing actions on food intake regulation and are mainly expressed in the hypothalamus and gut of mammals and fish. Both are involved in the regulation ...
Variación alélica y genotípica de Leucin-Aminopeptidasa (LAP-2) y fosfoglucomutasa (PGM) en Procambrus clarkii (Decapoda: Cambaridae), aclimatado a diferentes temperaturas y expuesto al endurecimiento térmicoAllelic and genotypic variation of Leucine-Aminopeptidase (LAP-2) and phosphoglucomutase (PGM,) in Procambarus clurkii (Decapoda: Cambaridae), acclimated at different temperatures and exposed to thermal hardening

Digestive response to restricted feeding in migratory yellow-rumped warblers
(University of Chicago Press, 2002-05)
Smaller guts and slow initial mass gains at stopover sites have led to the idea that digestive physiology limits refueling rates in migrating birds. We tested the digestive-limitation hypothesis in yellow-rumped warblers ...
