TL;DR: In this article, the authors investigated the hydrolysis rate of phosphatidylcholine as a function of pH, temperature, buffer concentration and buffer species, and found that the rate increased with increasing concentration of buffer species.

TL;DR: In this article, the cooperative mechanism of oleic acid/oleate vesicle formation is investigated under a variety of conditions and the size distribution of the vesicles obtained by injection of the surfactant stock solution in buffer solution covers a wide range, typically between 50 nm and 1.5 μm.
Abstract: The cooperative mechanism of oleic acid/oleate vesicle formation is investigated under a variety of conditions. When a stock solution of sodium oleate is injected in a buffered aqueous solution of pH 8.8, the time progress of the vesicles formation follows a sigmoidal pattern, which is indicative of an autocatalytic process. Autocatalysis is demonstrated by running experiments in the presence of preadded vesicles, which shortens the lag phase and accelerates the process of vesicle formation as measured by turbidity and electron microscopy. The size distribution of the vesicle diameters obtained by injection of the surfactant stock solution in buffer solution covers a wide range, typically between 50 nm and 1.5 μm. However, in the presence of extruded vesicles having respectively 50 and 100 nm diameter, a quite different situation is observed: the size distribution is then much narrower and strongly biased toward the diameter of the preadded vesicles (i.e., 50 or 100 nm). It is as if the vesicles which ar...

TL;DR: A new simple method for the determination of trans- and cis-resveratrol concentrations in aqueous solutions, transferable to 150 mM NaCl and 10 mM phosphate buffer solutions, which could be particularly useful for cell culture, ex vivo and in vivo studies.

TL;DR: The modified electrodes showed excellent catalytic activity, fast response time and high sensitivity toward oxidation of hydrazine in phosphate buffer solutions at pH range 4-8 and retained its initial response for at least 2 months if stored in dry ambient condition.
