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

Methods in molecular biology (Clifton, N.J.), 791, 23-32 (2011-09-14)
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
Christian Otto et al.
Bioinformatics (Oxford, England), 28(13), 1698-1704 (2012-05-15)
Cytosine DNA methylation is one of the major epigenetic modifications and influences gene expression, developmental processes, X-chromosome inactivation, and genomic imprinting. Aberrant methylation is furthermore known to be associated with several diseases including cancer. The gold standard to determine DNA

Current protocols in molecular biology, Chapter 21, Unit21-Unit21 (2012-08-09)
Unlike other methods to assess methylation, whole-genome shotgun bisulfite sequencing is used to generate quantitative genome-wide methylation profiles at single-nucleotide resolution. As described in this unit, this method allows for the quantitative measurement of methylation at each cytosine base by
