Chromatographic and Spectroscopic Analyses of Cannabinoids: A Narrative Review Focused on Cannabis Herbs and Oily Products
The latter is due to the presence of delta-9- tetrahydrocannabinol, a psychoactive substance. Recreational cannabis policies vary between different countries, which has led to the lack of a clearly ...
Persistent defect in SARS-CoV-2 humoral and cellular immunity in lung transplant recipients.
SARS-CoV-2 binding and neutralizing antibodies and lower IFN-γ responses to Wuhan, Delta and XBB1.5 variants as compared to HCW and NHR. Humoral immunity decreased between the two visits whereas cellular ...

Association between SARS-CoV-2 variants and post COVID-19 condition: findings from a longitudinal cohort study in the Belgian adult population
main exposure variable was the type of SARS-CoV-2 variants (i.e. Alpha, Delta, and Omicron), extracted from national surveillance data. The association between the different SARS-CoV-2 variants and PCC ...
Vaccine effectiveness against COVID-19 hospitalisation in adults (≥ 20 years) during Alpha- and Delta-dominant circulation: I-MOVE-COVID-19 and VEBIS SARI VE networks, Europe, 2021.
