Intravenous administration of paclitaxel in Sprague-Dawley rats: what is a safe dose?

abstract：:Equilibrative nucleoside transporters (ENTs) 1 and 2 reportedly accept fluorouracil as a substrate. Here, we evaluated ENT1/2 expression at the messenger RNA (mRNA), protein, and functional levels in a panel of four triple-negative breast cancer (TNBC) cell lines, BT-549, Hs578T, MDA-MB-231, and MDA-MB-435, and we exa...

abstract：:It was reported that gastric motility was delayed and gastric acid secretion was reduced in vagotomized dogs which mimics a low gastric acidity in humans. A delay in gastric motility causes long residence of amlodipine in the stomach. More unionized fractions of amlodipine could exist in less acidic conditions of gast...
