Identifying nanodescriptors to predict the toxicity of nanomaterials: a case study on titanium dioxide
2 and 3) performed under different exposure conditions (presence and/or absence of serum). Firstly, we identified the nanodescriptor(s) closely associated to biological endpoints. Secondly, we determined ...
QuilA-Adjuvanted T. gondii Lysate Antigens Trigger Robust Antibody and IFNγ+ T Cell Responses in Pigs Leading to Reduction in Parasite DNA in Tissues Upon Challenge InfectionImage
results show that both the vaccine candidate and the TLA immunization elicited strong serum IgG responses and elevated percentages of CD4 + CD8 + IFN γ+ T cells in T. gondii infected pigs. However, the TLA ...

of 17.5 ng/mL for the sum of the four PFAS s in serum was identified for 1‐year‐old children. Using PBPK modelling, this serum level of 17.5 ng/mL in children was estimated to correspond to long‐term ...
Gender‐dependent association between exhaled nitric oxide and the CC16 38AA genotype in young school children
allele promotes airway inflammation as measured by FeNO through a gender‐dependent association. Deficient levels of CC16 in the deep lung, measured noninvasively in urine, as a possible proxy for serum ...
Assessment of IgA anti-PT and IgG anti-ACT reflex testing to improve Bordetella pertussis serodiagnosis in recently vaccinated subjects.
evaluated in nine well characterized subject groups, aged 10-89 years (n = 390). Serum anti- PT IgG levels (>125 IU /mL) served as an indicator for a recent B. pertussis infection. Comparing symptomatic ...
Risk to human health related to the presence of perfluorooctane sulfonic acid and perfluorooctanoic acid in food
increase in serum total cholesterol in adults, and the decrease in antibody response at vaccination in children were identified as the critical effects. For PFOA, the increase in serum total cholesterol was ...
Sera from different age cohorts in Belgium show limited cross-neutralisation between the mumps vaccine and outbreak strains
if a difference in seroneutralising capacity against the vaccine and wild type viruses exists and if waning immunity could be detected. METHODS: In this study, 570 serum samples (age group 2-3y (N=96), ...
Seroprevalence of border disease virus and other pestiviruses in sheep in Algeria and associated risk factors.
6 and 24 months of age (n = 576) and from lambs younger than 6 months (n = 113). All samples were tested by RT- PCR as well as by Ag- ELISA, to detect Persistently Infected (PI) animals. Serum samples ...
Very Long Persistence of Botulinum Toxin B in a Patient’s Serum
method. Botulinum toxin was still detected in the serum up to 29 days after food consumption while it was not detected anymore in the faeces. Conclusion: The described case highlights i) prolonged presence ...
Evaluation of mycobacteria-specific gamma interferon and antibody responses before and after a single intradermal skin test in cattle naturally exposed to M. avium subsp. paratuberculosis and experimentally infected with M. bovis.
infected with a Belgian field strain of M. bovis. Heparinized blood, serum and fecal samples were collected at regular time intervals for mycobacteria-specific IFN-γ release assays, antibody analysis and for ...
