En la placenta humana, el sinciciotrofoblasto es la barrera que regula el transporte de nutrientes, solutos y agua entre la sangre materna y fetal. Dentro de este movimiento transepitelial se encuentra el del Na+ y su ...
Endothelial Epithelial Sodium Channel Inhibition Activates Endothelial Nitric Oxide Synthase via Phosphoinositide 3-Kinase/Akt in Small-Diameter Mesenteric Arteries
(American Heart Association, 2009)
Recent studies have shown that the epithelial sodium channel (ENaC) is expressed in vascular tissue. However,
the role that ENaC may play in the responses to vasoconstrictors and NO production has yet to be addressed. In ...
Efeitos da acidose lática nos processos da contratilidade cardíaca do teleósteo de água doce matrinxã, Brycon cephalus
(Universidade Federal de São CarlosBRUFSCarPrograma Interinstitucional de Pós-Graduação em Ciências Fisiológicas - PIPGCF, 2009-08-28)
In the majority of the fish species already studied, cardiac force contraction is sensitive to small changes in the extracellular pH. During intense swimming, the increased lactic acid (LA) levels significantly reduce the ...
Mechanism of hCG-induced spermiation in the toad Rhinella arenarum (Amphibia, Anura)
(Academic Press Inc Elsevier Science, 2010-08)
In Rhinella arenarum spermiation occurs as a consequence of LH/FSH increase during the amplexus or by a single dose of hCG, among other gonadotropins. The present study employs an in vitro system to study the mechanism of ...
Modulation of intracellular ph in human ovarian cancer
(2016-01-01)
To sustain tumor growth, the cancer cells need to adapt to low levels of oxygen (i.e., hypoxia) in the tumor tissue and to the tumor-associated acidic microenvironment. In this phenomenon, the activation of the sodium/proton ...
