Quantification of relative changes in specific mRNAs from frozen whole blood – methodological considerations and clinical implications

Background: Based on quantification of relative changes in lipopolysaccharide (LPS)-regulated mRNA transcripts, the present study aimed to establish a robotic method to isolate RNA from stabilized frozen whole blood suitable for gene expression analysis.

Methods: Whole blood (±LPS) was stored in EasyLyse? solution or PAXgene^® tubes (room temperature and ?70°C) for comparison of storage methods, then subjected to robotic isolation of total RNA...

On the methodology of Engineering Geodesy

Textbooks on geodetic surveying usually describe a very small number of principles which should provide the foundation of geodetic surveying. Here, the author argues that an applied field, such as engineering geodesy, has a methodology as foundation rather than a few principles...
