The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
In Belgium, CBD-containing e-liquids with a total THC content lower than 0.2% (w/w) are currently legal. In order to verify the compliance of the different CBD-containing e-cigarette liquids that are ...

with a total THC content lower than 0.2% (w/w) are currently legal. In order to verify the compliance of the different CBD-containing e-cigarette liquids that are available to the Belgian population, ...
Vaccine effectiveness against onward transmission of SARS-CoV2-infection by variant of concern and time since vaccination, Belgian contact tracing, 2021.
(Delta, 150-200 days after vaccination). We observed lower initial VE i in the age group 65-84 years (32% vs 46% in the age group 45-64 years for BNT162 b2) and faster waning. Hybrid immunity waned slower ...
Incidence and Risk Factors of COVID-19 Vaccine Breakthrough Infections: A Prospective Cohort Study in Belgium.
BNT162 b2, while mRNA-1273 was associated with a lower risk (HR0.68, 95% CI 0.67-0.69). A prior COVID-19-infection was protective against a breakthrough infection (HR0.23, 95% CI 0.23-0.24), as was an mRNA ...
Poor antibody response to BioNTech/Pfizer COVID-19 vaccination in SARS-CoV-2 naïve residents of nursing homes.
RBD Ab avidity, and neutralizing Ab against SARS-CoV-2 wild type and B.1.351 were assessed at days 0, 21, 28, and 49. RESULTS: SARS-CoV-2 naïve residents had lower Ab responses to BNT162 b2 mRNA ...
Deepening of In Silico Evaluation of SARS-CoV-2 Detection RT-qPCR Assays in the Context of New Variants
and January 2021. The lower inclusivity of the China CDC assay targeting the gene N has continued to decrease with new mismatches detected, whereas the other evaluated assays kept their inclusivity ...
Characterization and hazard identification of substandard and falsified antimicrobials encountered in Belgium
half of the samples were underdosed, resulting in a potential lower efficacy and so may aggravate illness of patients and induce bacterial resistance [2]. Moreover, in order to have an in-depth ...
Three-dimensional aesthetic assessment of class II patients before and after orthognathic surgery and its association with quantitative surgical changes.
were found, especially for the chin assessment. Orthodontists perceived the greatest improvement and laypeople the smallest. Overall, laypeople scored higher with less variability, but with lower intra- ...
Zona pellucida gene mRNA expression in human oocytes is related to oocyte maturity, zona inner layer retardance and fertilization competence.
mature (MII) and immature oocytes (MI / GV) or their corresponding CC, ZP1 /2 and 4 expression was lower in mature oocytes compared to the expression in immature oocytes (all P < 0.05) and ZP3 ...
Relation between Spongy Bone Density in the Maxilla and Skeletal Bone Density.
at five sites: maxilla midline, retromolar tuberosities, incisor, premolars, and molar regions. RESULTS: The bone density was lower in osteoporotic patients compared with the control patients. The bone ...
