Evaluating MIR and NIR Spectroscopy Coupled with Multivariate Analysis for Detection and Quantification of Additives in Tobacco Products.
possible to effectively estimate the concentration levels of the targeted molecules. The results also highlight the necessity of optimizing data pretreatment for accurate quantification of the target ...
The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
alleged therapeutic benefits, a low potential for abuse and lack of the typical psychoactive effects associated with the use of cannabis products containing high levels of ∆9-tetrahydrocannabinol (∆9- THC). ...
Spectroscopic approaches for conformity analysis of e-liquids
created with the intention of assisting smokers in quitting because they are believed to be less dangerous than conventional combustible cigarettes. With a range of flavors and nicotine levels to choose ...
The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV
(2023) Keywords: Cannabinoids CBD-liquids e-cigarettes LC-HRAM-MS Abstract: The use of cannabidiol or CBD products has skyrocketed in the last five years due to the alleged therapeutic benefits, a low ...
Poor antibody response to BioNTech/Pfizer COVID-19 vaccination in SARS-CoV-2 naïve residents of nursing homes.
vaccination than naïve staff. These poor responses involved lower levels of IgG to all spike domains, lower avidity of RBD IgG, and lower levels of Ab neutralizing the vaccine strain. No naïve resident had ...
CBD oils on the Belgian market: A validated MRM GC-MS/MS method for routine quality control using QuEChERS sample clean up
however, encountered for routine analyses due to the matrix complexity, high cost of cannabinoid standards and low Δ9- THC concentrations. An oily matrix could cause technical damages to analytical ...
Human challenge trial workshop: Focus on quality requirements for challenge agents, Langen, Germany, October 22, 2019.
exposure studies need to be safe and results should be meaningful, e.g. contribute to a better cure. Both in the US and in Europe, the level of Good Manufacturing Practice required is related to the phase of ...
Zona pellucida gene mRNA expression in human oocytes is related to oocyte maturity, zona inner layer retardance and fertilization competence.
p.292-303 (2017) Abstract: STUDY QUESTION: Do the mRNA expression levels of zona pellucida (ZP) genes, ZP1, 2, 3 and 4 in oocyte and cumulus cells (CC) reveal relevant information on the oocyte? SUMMARY ...
The role of methylation, DNA polymorphisms and microRNAs on HLA-G expression in human embryonic stem cells.
HLA-G in eight hESC lines. We showed that, while the gross expression levels of HLA-G are controlled by promoter methylation, the genetic constitution of the HLA-G 3’ UTR, more specifically the 14bp ...
An application of mass spectrometry for quality control of biologicals: Highly sensitive profiling of plasma residuals in human plasma-derived immunoglobulin.
and low-abundant protein enrichment with a combinatorial peptide ligand library (ProteoMiner™, Bio-Rad). The latter allowed a higher number of identifications. Highly sensitive detection of ...
