... anhydrase catecholamine isoproterenol short-circuiting A reduction in blood pH during blood capillary transit enhances O 2 delivery in vertebrates through the Bohr effect, a physiological mechanism that has been studied extensively for over a century and defined as the decrease in haemoglobin...

... upon isoproterenol treatment: it is redistributed from the membraneous to the cytosolic fraction, as revealed by quantitative image analysis of western blots. Here we confirm and extend this observation by laser scanning confocal and immunogold electron microscopy. In the presence of isoproterenol...

... and incubated with the hormones dexamethasone (10 μmol l –1 ), prolactin (1 μmol l –1 ) or triiodothyronine (100 μmol l –1 ) or with the autonomic secretagogues isoproterenol (100 μmol l –1 ) or carbamylcholine chloride (100 μmol l –1 ). Basal secretion of PC was greater at 30 days of age than at 70 days. Co...

... or isoproterenol at 10 −6 mol l −1 significantly increased the rate of brush-border transport, but not the apparent affinity constant ( K t ). Activation was dependent on hormone concentration. In contrast, insulin was without effect on transport rates, nor did it counteract activation by glucagon-family peptides...

...M. A. Gallardo; J. Planas; J. Sánchez ABSTRACT We studied the uptake of L-serine by trout red blood cells and the effect of a -adrenergic agonist (isoproterenol) on this process. The results obtained indicate that L-serine is taken up by these cells by means of a concentrative process. The uptake...

... in cardiac cells (L-type) whose gating is affected in different ways by β -adrenoceptor and 1,4-dihydropyridine agonists. We have analysed single calcium channel currents (i) in myocytes from rat hearts in the absence and presence of isoproterenol or 8-bromo-cAMP. We have found that both compounds have...
