Propofol-induced Inhibition of Catecholamine Release Is Reversed by Maintaining Calcium Influx.

abstract：BACKGROUND:In previous studies, the authors showed that anesthetics affect the expression ratios of many genes in rat liver. microRNAs (miRNA) negatively regulate more than 30% of genes in cells, and control cell proliferation, inflammation, and metabolism. The authors hypothesized that anesthetics influence miRNA expr...
