Simultaneous quantification of 2',2'-difluorodeoxycytidine and 2',2'-difluorodeoxyuridine nucleosides and nucleotides in white blood cells using porous graphitic carbon chromatography coupled with tandem mass spectrometry.

29 Sep 2009 A novel assay for the simultaneous quantification of the widely used anticancer agent 2',2'-difluorodeoxycytidine (gemcitabine; dFdC), its deaminated metabolite 2',2'-difluorodeoxyuridine (dFdU) and their mono-, di- and triphosphates (dFdCMP, ... Read more...

Detection and characterization of group A rotaviruses in children hospitalized with acute gastroenteritis in Norway, 2006-2008.

29 Sep 2009 To assess the genetic diversity of rotavirus strains in Norway, the distribution of rotavirus genotypes was studied in children admitted to hospital with acute gastroenteritis. The detection of rotavirus in stool samples was compared using an ... Read more...

The relative exposure of the operating room staff to sevoflurane during intracerebral surgery.

29 Sep 2009 BACKGROUND: Our primary aim in this study was to investigate whether escape of the volatile anesthetic sevoflurane from the surgical site during craniotomy for tumor resection increases the exposure of the neurosurgeon to the anesthetic when ... Read more...

Technical information about 'Chromatography'

Definition: Techniques used to separate mixtures of substances based on differences in the relative affinities of the substances for mobile and stationary phases. A mobile phase (fluid or gas) passes through a column containing a stationary phase of porous solid or liquid coated on a solid support. Usage is both analytical for small amounts and preparative for bulk amounts.
