Hair mercury and urinary cadmium levels in Belgian children and their mothers within the framework of the COPHES/DEMOCOPHES projects.
(≤ 45 years) living in urban or rural areas of Belgium. The geometric mean levels for mercury in hair were 0.383 μg/g and 0.204 μg/g for respectively mothers and children. Cadmium in mother’s and ...
Mercury and cadmium levels in Belgian children and their mothers
levels were measured in centrifuged and acidified urine by ICP- MS (LOQ =0.01µg/g), while total mercury was analyzed by FIMS on hydrolyzed hairs (LOQ =0.08µg/g). Results The geometric mean level for ...
Influenza A/H1N1 vaccine in patients treated by kidney transplant or dialysis: a cohort study36521
AS03-adjuvanted). We measured the neutralizing antibodies against A/ H1N1 /2009, the geometric mean (GM) titers, the GM titer ratios (T1 / T0) with 95% confidence intervals, and the seroconversion rate (responders: ...
Calibration of the Ph. Eur. Biological Reference Preparation (BRP) for Tetanus Vaccine (Adsorbed) Batch 3).
Preparation A, the geometric mean (GM) potency estimate (with 95 % confidence interval (CI)) in guinea pigs for alllaboratories that provided valid results (n = 6) was 488.5 (354.2-673.6) IU /ampoule. For valid ...
Standardization of hepatitis E virus (HEV) nucleic acid amplification technique-based assays: an initial study to evaluate a panel of HEV strains and investigate laboratory performance34020
6 to 4 log(10) copies/ml, the standard deviations of the geometric means of the samples ranged between 0.38 and 1.09. Except for one equivocal result, HEV RNA was not detected in the negative samples. ...
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 ...
In vitro antifungal susceptibilities and amplified fragment length polymorphism genotyping of a worldwide collection of 350 clinical, veterinary, and environmental Cryptococcus gattii isolates36867
AFLP4 (n = 76) and AFLP6 (n = 103). The clinical AFLP6 isolates had significantly higher geometric mean MIC s for flucytosine and fluconazole than the clinical AFLP4 isolates. Of the seven antifungal ...
Multicenter study for defining the breakpoint for rifampin resistance in Neisseria meningitidis by rpoB sequencing36888
gene was sequenced. Sequences differing by at least one nucleotide were defined as unique rpoB alleles. The geometric mean of the MIC s was calculated for isolates displaying the same allele. The ...
Early waning of maternal measles antibodies in era of measles elimination: longitudinal study
significantly fewer IgG antibodies (geometric mean titre 779 (95% confidence interval 581 to 1045) mIU/ml) than did naturally immune women (2687 (2126 to 3373) mIU/ml) (P <0.001). Maternal values were highly ...
Real-time reverse transcription PCR for the quantification of the mntH expression of Salmonella enterica as a function of growth phase and phagosome-like conditions36757
in different S. enterica strains under various biological conditions, the ratio mntH mRNA level to the normalization factor was determined. The latter is the geometric mean of the RNA level of three ...
