The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.

using the ‘total error’ approach, applying accuracy profiles and conforming to ISO17025. None of the analysed samples exceeded the legal limit for the total amount of ∆9- THC present. However, of the 20 ...

applying accuracy profiles and conforming to ISO17025. None of the analysed samples exceeded the legal limit for the total amount of ∆9- THC present. However, of the 20 CBD-liquids investigated in this ...

CBD oils on the Belgian market: A validated MRM GC-MS/MS method for routine quality control using QuEChERS sample clean up

(0.05–0.1–0.2% (w/v)) for CBN. The detection limits for CBT, CBD, CBC, Δ8- THC, CBN and for the other cannabinoids of interest, were 10 and 14 ng/mL respectively. The accuracy profile values for CBD and CBN showed ...

Use of Whole Genome Sequencing Data for a First in Silico Specificity Evaluation of the RT-qPCR Assays Used for SARS-CoV-2 Detection.

started in December 2019. COVID-19 cases are confirmed by the detection of SARS-CoV-2 RNA in biological samples by RT-qPCR. However, limited numbers of SARS-CoV-2 genomes were available when the first ...

A new approach to define acceptance limits for hematology in external quality assessment schemes.

Laboratory Medicine (EQALM) decided to perform a statistical study with the aim of establishing appropriate acceptance limits (AL) allowing harmonization between the evaluation procedures of European EQAS ...

Advanced Methods for Dose and Regimen Finding During Drug Development: Summary of the EMA/EFPIA Workshop on Dose Finding (London 4-5 December 2014).

and adaptive studies). Pairwise comparisons were also discussed during the workshop; however, mostly for historical reasons. This paper discusses the added value and limitations of these methods as well ...

Development and validation of a HS/GC-MS method for the simultaneous analysis of diacetyl and acetylpropionyl in electronic cigarette refills

5ppm for diacetyl and acetylpropionyl. The obtained accuracy profiles show that the beta-expectation tolerance intervals did not exceed the acceptance limits of+/-10%, meaning that 95% of future ...

Zona pellucida gene mRNA expression in human oocytes is related to oocyte maturity, zona inner layer retardance and fertilization competence.

response resulted in a noninvasive oocyte fertilization prediction model. LARGE SCALE DATA: Not applicable. LIMITATIONS, REASONS FOR CAUTION: This is a retrospective study and the relation of oocyte mRNA ...

Vaccine, Volume 35, Issue 15, p.1844-1855 (2017) Abstract: Lessons learnt from the 2009 (H1N1) flu pandemic highlighted factors limiting the capacity to collect European data on vaccine exposure, safety and ...

The fate of buccal bone around dental implants. A 12-month postloading follow-up study.

(one stage vs. two stages) did not influence the rate of bone resorption (P = 0.23). CONCLUSION: Within the limitations of this study, one might question the necessity of having a thick bone plate at the ...
