Dietary intake of hexabromocyclododecane diastereoisomers (α-, β-, and γ-HBCD) in the Belgian adult population.

Hydrocarbons, Brominated Male Stereoisomerism Abstract: A study was performed to assess exposure of the Belgian population to HBCD diastereoisomers. Measurements of HBCD were performed by UPLC- MS / MS, on 45 ...

Determination of the volume-specific surface area by using transmission electron tomography for characterization and definition of nanomaterials.

feasibility to visualize and measure silica and gold NM in suspension using conventional bright field electron tomography. RESULTS: The general morphology of gold and silica NM was visualized in 3D by ...

Measles resurgence in Belgium from January to mid-April 2011: a preliminary report.

consequence of insufficient vaccine coverage in previous years. Efforts to communicate the benefits of measles vaccination to the public and to advise health professionals on control measures and outbreak ...

Are we hitting immunity targets? The 2006 age-specific seroprevalence of measles, mumps, rubella, diphtheria and tetanus in Belgium36577

Immunoglobulins against measles, mumps, rubella (MMR) and diphtheria at all available ages (1-65 years), and against tetanus in >40-year-olds, were measured by ELISA. Age-standardized overall seronegativity for ...

A validated ultra high pressure liquid chromatographic method for qualification and quantification of folic acid in pharmaceutical preparations.

measurement uncertainty (accuracy profile) and robustness tests. A UHPLC method was obtained for the identification and quantification of folic acid in pharmaceutical preparations, which will cut analysis times ...

Cattle, sheep and pigs vaccinated against foot and mouth disease: does trade in these animals and their products present a risk of transmitting the disease?

information suggests that, provided there is compliance with essential criteria concerning vaccines, vaccination and other zoosanitary measures (especially quarantine and ante- and post-mortem inspection), the ...

Diagnostic performance and application of two commercial cell viability assays in foot-and-mouth disease research.

(abs)) assay demonstrated similar high sensitivities (97%, 99% and 98%, respectively), specificities (100%, 98% and 99%, respectively), accuracy measures (0.99, 0.98 and 0.98, respectively), precision ...

Qualitative risk assessment in a data-scarce environment: a model to assess the impact of control measures on spread of African Swine Fever.

in the EU if disease were introduced. The aim was to develop a tool to evaluate how current control or preventive measures mitigate the risk of spread and giving decision makers the means to review how ...

Immunogenicity of an adjuvanted 2009 pandemic influenza A (H1N1) vaccine in haemodialysed patients

and controls. Antibody level was measured using a seroneutralization assay before (D(0)) and 30 days after (D(30)) a single 3.75 mug vaccine dose. Specimens were tested in quadruplicates. Geometric mean ...

Persistence of free-living protozoan communities across rearing cycles in commercial poultry houses.

remained highly habitat and farm specific. Unlike in natural environments, protozoan communities inside broiler houses are therefore not seasonal. Our results imply that currently used biosecurity measures ...
