BURNOUT NO ESPORTE: REVISAO SISTEMATICA NA BASE ScienceDirect

Basolateral membrane Na+/H+ antiport, Na+/base cotransport, and Na+-independent Cl-/base exchange in the rabbit S3 proximal tubule.

The basolateral membrane Na+ and Cl(-)-dependent acid-base transport processes were studied in the isolated perfused rabbit S3 proximal straight tubule. Intracellular pH (pHi) was measured with 2'7'-biscarboxyethyl-5,6-carboxyfluorescein (BCECF) and a microfluorometer coupled to the tubule perfusion apparatus. Reduction of basolateral HCO3- from 25 to 5 mM caused pHi to decrease at a rate of 0....

Acid-base effects on intestinal Na(+) absorption and vesicular trafficking.

We examined for vesicular trafficking of the Na(+)/H(+) exchanger (NHE) in pH-stimulated ileal and CO(2)-stimulated colonic Na(+) absorption. Subapical vesicles in rat distal ileum were quantified by transmission electron microscopy at x27,500 magnification. Internalization of ileal apical membranes labeled with FITC-phytohemagglutinin was assessed using confocal microscopy, and pH-stimulated i...

No fuzzy space for intracellular Na+ in healthy ventricular myocytes

In virtually all mammalian cells, the traditional roles of the Na/K pump include establishing and maintaining transcellular gradients of Na and K and modulating steady-state gradients of H and Ca. By regulating intracellular Na, [Na]i, the Na/K pump also makes a major contribution to cellular volume control, although some aspects of this modulation of osmolarity are not completely understood (A...

Diferenciação Intersetorial Na Interação Entre Empresas E Universidades No Brasil

This short paper presents results based on special tabulations prepared by IBGE, using data from Pintec in order to focus on the interaction between firms and universities in the Brazilian industry. The basic hypothesis states that the relevance of universities as a source of information to the firms’ innovation activities is greater when firms are engaged in R&D activities (both internal and e...
