Sample preparation methods for elemental analysis in electronic cigarette aerosols: a critical review
e-cigarette consists of an e-liquid and a heating device, generating an aerosol that the user can inhale. Recently, several studies have shown that metals and metalloids, including As, Cd, and Pb, known ...
Characterization of functional nanoparticles applied in face masks by STEM-EDX
create textiles with enhanced fabric properties, a trend exemplified within the production of face masks since the onset of the Covid-19 pandemic. The use of silver (Ag) is advertised in several ...
Evaluation of a point-of-care test for the diagnosis of Taenia solium neurocysticercosis in rural southern Tanzania: a diagnostic accuracy study.
Abstract: BACKGROUND: Neurocysticercosis is a common cause of epilepsy in Taenia solium-endemic areas in sub-Saharan Africa but is often undiagnosed because of an absence of affordable diagnostic tools. This ...
The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
CBD-liquids investigated in this study, only 30% of the samples contained an amount of CBD that was within 10% deviation of the label claim. Moreover, the CBD e-liquids labelled “full/broad spectrum” consisted ...
Homologous versus heterologous prime-boost COVID-19 vaccination: impact on clinical severity of Omicron among hospitalized COVID-19 patients in Belgium
Microbiology and Infectious Diseases (2023) Abstract: Background We investigated the real-world effectiveness of a heterologous versus homologous primeboost vaccination scheme against severe clinical outcomes of ...

Abstract: For 1 year now, the world is undergoing a coronavirus disease-2019 (COVID-19) pandemic due to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The most widely used method for ...
Chemometrics and chromatographic fingerprints to classify plant food supplements according to the content of regulated plants.
regulated or toxic plants is an important issue, especially when the products are purchased from irregular sources. This paper focusses on this problem by using specific chromatographic fingerprints for five ...
Detection of regulated herbs and plants in plant food supplements and traditional medicines using infrared spectroscopy.
compressed into tablets or capsules. The classical identification approaches based on micro- and macroscopy are therefore not possible anymore. In this paper infrared spectroscopy, combined with attenuated ...
