A calcium-containing electrolyte-balanced hydroxyethyl starch (HES) solution is associated with higher factor VIII activity than is a non-balanced HES solution, but does not affect von Willebrand factor function or thromboelastometric measurements--results of a model of in vitro haemodilution.

Background: Hydroxyethyl starch (HES) is known to impair blood coagulation. The impact of calcium-containing, balanced carrier solutions of HES on coagulation is controversial. We investigated the effects of increasing degrees of haemodilution with modern 6%, electrolyte-balanced HES vs non-balanced HES on coagulation in vitro, and compared the balanced HES to a balanced crystalloid solution for an internal control.

Economic high-throughput-identification of influenza A subtypes from clinical specimens with a DNA-oligonucleotide microarray in an outbreak situation.

Influenza A surface proteins H (haemagglutinin) and N (neuraminidase) occur in sixteen and nine distinct genotypes, respectively. The need for a timely production of vaccinations in case of pandemics or seasonal epidemics requires rapid typing methods for the determination of these alleles. The aim of the present study was to develop and improve a rapid and economic assay for determining H and N subtypes of influenza A from patient samples.
