The purpose of this study was to predict the stability of imipenem in a mixed infusion. The hydrolysis of imipenem in aqueous solution was found to be accelerated by pH, and by increasing concentrations of sodium bisulfite (SBS) and L-cysteine.

Lodgepole wood chips were pretreated by sulfite pretreatment to overcome recalcitrance of lignocelluloses (SPORL) at 25% solids loading and 180 °C for 20 min with sulfuric acid and sodium bisulfite charges of 2.2 and 8 wt/wt% on an oven-dry wood

DNA methylation patterns in CpG-rich regions of promoter, CpG islands, are concerned in regulation of gene expression in mammalian cells. Excessive methylation of CpG dinucleotides in promoter represses the gene expression. In cancer, especially, gene silencing is occurred through aberrant

RNA silencing has been exploited to produce transgenic plants with resistance to viral pathogens via posttranscriptional gene silencing (PTGS). In some cases, this technology is difficult to apply due to the instability of inverted repeat (IR) constructs during cloning and

A liquid chromatography-tandem mass spectrometry method for the determination of andrographolide sodium bisulphite (ASB) in rat urine was established and validated. To our knowledge, the analytical method is the first developed assay for the determination of ASB in urine samples.
