Differential adjustment in gill Na(+)/K(+)- and V-ATPase activities and transporter mRNA expression during osmoregulatory acclimation in the cinnamon shrimp Macrobrachium amazonicum (Decapoda, Palaemonidae)
(COMPANY OF BIOLOGISTS LTD, 2010)
We evaluate osmotic and chloride (Cl(-)) regulatory capability in the diadromous shrimp Macrobrachium amazonicum, and the accompanying alterations in hemolymph osmolality and [Cl(-)], gill Na(+)/K(+)-ATPase activity, and ...
O papel da enzima Na+,K+-ATPase no déficit cognitivo e no efeito profilático induzido pelo exercício físico após o traumatismo crânio-encefálico
(Universidade Federal de Santa MariaBRFarmacologiaUFSMPrograma de Pós-Graduação em Farmacologia, 2009-09-17)
Traumatic Brain Injury (TBI) is the major cause of death or cognitive deficits in industrialized countries. Although studies have indicate that the oxidative stress and functional deficits after TBI are connected events, ...
Regulation by the exogenous polyamine spermidine of Na,K-ATPase activity from the gills of the euryhaline swimming crab Callinectes danae (Brachyura, Portunidae)
(ELSEVIER SCIENCE INC, 2008)
Euryhaline crustaceans rarely hyporegulates and employ the driving force of the Na,K-ATPase, located at the basal surface of the gill epithelium, to maintain their hemolymph osmolality within a range compatible with cell ...
Efeito diferencial do diazepam sobre a atividade da enzima Na+,K+-ATPase no hipocampo e córtex entorrinal
(Universidade Federal de Santa MariaBrasilFarmacologiaUFSMPrograma de Pós-Graduação em FarmacologiaCentro de Ciências da Saúde, 2016-11-29)
Na+,K+-ATPase is ubiquitously expressed in the plasma membrane of all animal cells where serves as the principal regulator of intracellular ion homeostasis. Na+,K+-ATPase activity is activated by Na+ and K+ and current ...
Steady-state analysis of enzymes with non-Michaelis-Menten kinetics: The transport mechanism of Na + /K + -ATPase
(American Society for Biochemistry and Molecular Biology, 2018-01)
Procedures to define kinetic mechanisms from catalytic activity measurements that obey the Michaelis-Menten equation are well-established. In contrast, analytical tools for enzymes displaying non-Michaelis-Menten kinetics ...
Papel do processo oxidativo/inflamatório na fisiopatologia induzida por concussões recorrentes em ratos jovens
(Universidade Federal de Santa MariaBrasilBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica ToxicológicaCentro de Ciências Naturais e Exatas, 2022-08-05)
Concussion can be defined as a change in brain function caused by an external force. In recent years, it has received greater attention from the scientific community for its subtle effects, which can add up and worsen the ...
A comparative study between a brain Na+,K+-ATPase inhibitor (endobain E) and ascorbic acid
(Springer/Plenum Publishers, 2003-06)
In the search of Na+,K+-ATPase modulators, we have reported the isolation by gel filtration and HPLC of a brain fraction, termed endobain E, which highly inhibits Na+,K+-ATPase activity. In the present study we compared ...
Na,K-ATPase activity and epithelial interfaces in gills of the freshwater shrimp Macrobrachium amazonicum (Decapoda, Palaemonidae)
(ELSEVIER SCIENCE INC, 2009)
Diadromous freshwater shrimps are exposed to brackish water both as an obligatory part of their larval life cycle and during adult reproductive migration; their well-developed osmoregulatory ability is crucial to survival ...
Kinectics of Na+, K+-ATPase inhibition by calcitonin and neurotensin
(Research Trends, 2014-01)
The kinetics of interactions between the peptides calcitonin or neurotensin, and synaptosomal membrane Na+, K+-ATPase activity was characterized in this study. Calcitonin is a 32-amino acid peptide produced by the thyroid ...
