Paraoxonase Inhibition by Propranolol
There are many evidences that human serum paraoxonase activity modifies plasma lipid profile and paraoxonase has an antiatherogenic property. Non-selective beta-blockers affect plasma lipid profile too, but they have atherogenic property when patients take these drugs in long term. In this study the effect of propranolol, a non-selective beta-blocker, on paraoxonase activity was investigated. L...

متن کاملA mechanism for tamoxifen-mediated inhibition of acidification.
Tamoxifen has been reported to inhibit acidification of cytoplasmic organelles in mammalian cells. Here, the mechanism of this inhibition is investigated using in vitro assays on isolated organelles and liposomes. Tamoxifen inhibited ATP-dependent acidification in organelles from a variety of sources, including isolated microsomes from mammalian cells, vacuoles from Saccharomyces cerevisiae, an...
متن کاملTransient complex I inhibition at the onset of reperfusion by extracellular acidification decreases cardiac injury.
A reversible inhibition of mitochondrial respiration by complex I inhibition at the onset of reperfusion decreases injury in buffer-perfused hearts. Administration of acidic reperfusate for a brief period at reperfusion decreases cardiac injury. We asked if acidification treatment decreased cardiac injury during reperfusion by inhibiting complex I. Exposure of isolated mouse heart mitochondria ...
متن کاملInhibition of the bicarbonate exit step in urinary acidification by a disulfonic stilbene.
Acidification of the luminal solution by the isolated turtle bladder involves H(+) secretion by a pump at the luminal membrane. The OH(-) dissociated in this process reacts with CO(2) and forms HCO(3) (-) which moves passively out of the cell across the serosal cell membrane. In the present study, this exit step for HCO(3) (-) was inhibited by serosal addition of the disulfonic stilbene, SITS, ...
