The influence of peroxide bleaching and slack-mercerization on the amount of acidic groups in regenerated fibres (viscose, modal and lyocell) were studied. Bleaching with hydrogen peroxide causes some oxidative cellulose damage and, therefore, a larger amount of carboxyl groups (presumably formed at the end of cellulose chains). Slack-mercerization did not significantly change the total amount of acidic groups in the fibres, but their accessibility to cationic polyelectrolytes, in particular to polymers with high molecular weight was substantially lowered.

A prospective unblinded comparative evaluation of three assays for the detection of enteroviral RNA performed on 83 positive and 79 negative cerebrospinal fluid samples showed initial and resolved sensitivities of 90.4%and 98.8%, respectively, for the Cepheid GeneXpert enterovirus assay; 94.0% and 97.6%, respectively, for the Argene enterovirus consensus kit; and 100% and 100%, respectively, for an in-house real-time PCR. The initial and resolved specificities were 100% for all three assays.
