A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.

and to compare these with standard approaches, i.e. dynamic light scattering (DLS), nanoparticle tracking analysis (NTA), microscopy (TEM), membrane filtration, centrifugation and dialysis. Seven ...

Relevance of Bt toxin interaction studies for environmental risk assessment of genetically modified crops.

proteins may occur and thereby increase the impact of the stacked GM event on nontarget invertebrates compared to plants expressing a single Bt gene. On the basis of bioassay data available for Bt toxins ...

Identification of filamentous fungi isolates by MALDI-TOF mass spectrometry: clinical evaluation of an extended reference spectra library.

reference spectra. To this end, a large in-house library containing 760 strains and representing 472 species was built and evaluated on 390 clinical isolates by comparing MALDI- TOF MS with the classical ...

Childhood Leukaemia incidence around the Belgian nuclear sites: Surrogate exposure modelling.

Belgium cancer Cancer incidence cancer registry childhood leukaemia CHILDREN comparing Control data evidence exposure Flemish generalized additive models health Hypothesis incidence Industries Industry ...

The dermatophyte species Arthroderma benhamiae: intraspecies variability and mating behaviour.

benhamiae wild strains from the same geographical area (Switzerland) was studied by comparing their morphology, assessing their molecular variability using internal transcribed spacer (ITS) and 28S rRNA gene ...

Genetic re-identification and antifungal susceptibility testing of Aspergillus section Nigri strains of the BCCM/IHEM collection.

environmental and clinical samples. The susceptibility for antifungal drugs was compared between A. niger and Aspergillus tubingensis. Strains were identified based on morphological and molecular data and ...

State-of-the-art lentiviral vectors for research use: risk assessment and biosafety recommendations.

different strategies used to improve LV biosafety by comparing state-of-the-art and emerging LV production systems and highlighting biosafety issues that can arise during their contained use. The few existing ...

Physical characteristics of the back are not predictive of low back pain in healthy workers: a prospective study.

(‘mildly symptomatic’ workers). RESULTS: In the group of ‘asymptomatic’ workers, obese workers showed a more than twofold-increased risk on the development of LBP as compared to non-obese colleagues (RR ...

An objective method for the evaluation of eye irritation in vivo.

observation times. The corneal swelling scores measured after 24 hr using the ultrasonic pachometer are comparable with those reported in the literature, which were obtained by optical pachometry. The good ...

The enucleated eye test: A comparison of the use of ultrasonic and optic pachometers.

introduced recently into our laboratory for use in the eye-irritation test using enucleated rabbit eyes. We have compared the performance of this kind of pachometer with that of the optical pachometer. The ...
