Persad S,Gupta KK,Dhalla NS.Status of Ca(2+)-channels in hearts perfused with Ca(2+)-free medium as well as upon reperfusion (Ca(2+)-paradox). Journal of Molecular and Cellular Cardiology . 1995Persad, S, Gupta, KK, Dhalla, NS (1995) Status of Ca2+-channels in hearts perfused ...
rich environments in the human body and in the culture - for example, 45–86 nM in the RBC cytosol, ~40 μM in the PV space, and ~1 mM in the human plasma25,26 - we fur- ther evaluated the effect of CPA and TG in Ca2+-free medium after selective membrane permeabilization...
Furthermore, αLA-mediated GLP-1 secretion by STC-1 cells was significantly inhibited by Ca2+- free medium, implying that Ca2+ influx drives FFA4-mediated GLP-1 secretion[13]. However, nifedipine (an L-type Ca2+ chan- nel blocker), thapsigargin, and U-73122 (a phospholipase C inhibitor...
4B). Using immunofluorescence, we confirmed that both EDTA and Ca2+-free medium inhibited Nrf2 nuclear translocation (Fig. 5E). It is worth noting that the ratio of Nrf2-positive cells in the nucleus in the EDTA-treated and Ca2+-free group were similar to the control group, suggesting that...
2. 2. The response to caffeine was rapidly reduced after incubation in a Ca2+-free medium and was abolished after 6 min of incubation. However, the response to caffeine in Ca2+-free medium 30 sec. after pretreatment with 10 mM K+ in normal Ca medium was larger. 3. 3. These results ...

the tissue was further digested (30 min at 35 °C) in the low Ca2+ solution containing in addition collagenase (type H or F; 1-3 mg ml_1), then rinsed several times with the enzyme-free low Ca2+ solution and then rinsed again in S-MEM (Eagle) spinner Ca2+-free medium (GibcoBRL...
In dystrophic soleus (Sol) and extensor digitorum longus (EDL) muscles exposed to Na+-free medium, there was a decrease in aiNa associated with a hyperpolarization of the membrane and the generation of a transient contracture. By contrast, exposing normal or denervated EDL muscles to Na+-free...
We investigated the cellular distribution of the (CaCC), , in the urethra of , , and by both immunofluorescence and PCR. We studied its role in urethral contractility by examining the effects of -free medium and of several CaCC inhibitors on noradrenergic and cholinergic excitatory responses, and...
1. 1. Neuropeptide Y (NPY) potentiated the contractile responses induced by electrical transmural stimulation, noradrenaline and KCl in the rabbit mesenteric artery. 2. 2. In preparations treated with noradrenaline or KCl in Ca 2+ free medium, NPY also potentiated the contractile response induced ...
