Chromatographic fingerprint development for the detection of tobacco varieties in commercial tobacco products
a chromatographic fingerprinting method was developed to produce unique fingerprints of tobacco varieties. This method aims to enable the verification of declared compositions and contributes to the detection of ...
The performance of a point-of-care test for the diagnosis of Neurocysticercosis in a resource-poor community setting in Zambia- a diagnostic accuracy study.
at any stage was limited for all tests (TS POC, rT24H- EITB and antigen ELISA). With further development the TS POC CC may enable a better detection and faster referral of NCC patients who may benefit ...
Evaluating MIR and NIR Spectroscopy Coupled with Multivariate Analysis for Detection and Quantification of Additives in Tobacco Products.
Abstract: The detection and quantification of additives in tobacco products are critical for ensuring consumer safety and compliance with regulatory standards. Traditional analytical techniques, like gas ...
Characterization of functional nanoparticles applied in face masks by STEM-EDX
embedded within the fibres, while in the other three cases it is at least partly present on the surface of fibres. The amount of silver-containting particles detected in each sample is too low to build ...
Pyrogen testing of phage therapeutic products
cell wall, flagellin, etc. are not detected by those tests. As phages are being produced in a growing variety of bacterial host strains, including gram-positive bacteria, an expansion of the QC workflow ...
Evaluation of a point-of-care test for the diagnosis of Taenia solium neurocysticercosis in rural southern Tanzania: a diagnostic accuracy study.
study evaluated the diagnostic accuracy of a T solium cysticercosis antibody-detecting lateral-flow point-of-care assay (TS POC test) for the neuroimaging-based diagnosis of neurocysticercosis. METHODS: ...
Validation of an animal-free analytical method for the detection of bacterial endotoxins in human vaccines

Spectroscopic approaches for conformity analysis of e-liquids
classify samples according to nicotine and present additives. So, their presence in new suspected samples could be detected. In a second step, PLS regression was applied to estimate the nicotine ...
The GEONs API-fingerprint program: Tackling falsifications of APIs
casualties happened when altered API s escaped detection in routine analytical testing. Any form of tampering the content or information about the content might affect the quality of the API, the finished ...
Poor antibody response to BioNTech/Pfizer COVID-19 vaccination in SARS-CoV-2 naïve residents of nursing homes.
detectable neutralizing Ab to the B.1.351 variant. In contrast, SARS-CoV-2 infected residents had high responses to mRNA vaccination, with Ab levels comparable to infected staff. Cluster analysis revealed that ...
