Optimization and validation of a micellar electrokinetic chromatographic method for the analysis of several angiotensin-II-receptor antagonists
for the separation of six angiotensin- II-receptor antagonists (ARA- II s): candesartan, eprosartan mesylate, irbesartan, losartan potassium, telmisartan, and valsartan. A face-centred central composite ...
Influence of the growth substrate on the mycolic acid profiles of mycobacteria.
results indicate that mycobacteria respond to the growth substrate by changing the mycolic acid composition of their cell wall, pointing at the importance of the growth substrate for mycolic acid profiling ...
Effects of inhalation of dust and endotoxin on respiratory tracts of pigs.
6 days to feed flour dust (1 to 15 mg/m3) and dustborne endotoxins (50 to 2,500 ng/m3). Effects were evaluated by measuring albumin concentration, lactate dehydrogenase (LDH) activity, cell composition of ...

Half-fraction and full factorial designs versus central composite design for retention modelling in reversed-phase ion-pair liquid chromatography
studied using a face-centred central composite design. It is examined whether smaller half-fractional and full factorial designs with fewer experiments tend to reliably predict retention times of the latter ...
Experimental design for the rapid selection of separation conditions for methyl and propyl parahydroxybenzoate, phenylephrine hydrochloride and chlorphenamine maleate by ion-pair liquid chromatography
liquid chromatographic (LC) systems. A face-centred central composite design was applied to study the impact of four LC mobile phase parameters and parameter interactions on the retention of these four ...

Bt-maize event MON 88017 expressing Cry3Bb1 does not cause harm to non-target organisms
adults. Impacts on NTO s caused by potential unintended changes in maize MON 88017 are not expected to occur, as no differences in composition, phenotypic characteristics and plant- NTO interactions were ...
