Since the 1990s, regular comparisons of gamma-ray spectrometry in Switzerland were organized to improve laboratory abilities to measure the radioactivity in the environment and food stuffs at typical routine levels. The activity concentration of the test samples and the evaluation of the associated uncertainties remained each year the main required test result. Over the years, the comparisons used certified reference solutions as well as environmental samples. The aim of this study is to research the effect of the comparisons on measurement quality. An analysis of the seven last interlaboratory comparisons revealed that the Swiss measurement capability is up to date. In addition, the results showed that the participants now have an improved evaluation of the uncertainties associated with their measurement.

Astrocytoma is a common type of glioma and a frequent cause of brain tumour-related epilepsy. Although the link between glioma and epilepsy is well established, the precise mechanisms underlying epileptogenesis in astrocytoma remain poorly understood. In this study, we performed proteomic analysis of astrocytoma tissue from patients with and without seizures using mass spectrometry-based techniques.

Background: Vitamin K-dependent γ-glutamic acid carboxylation (Gla) proteins are calcium-binding and membrane-associated, participating in coagulation, bone turnover, and cancer biology. The molecular function of transmembrane proline-rich Gla proteins (PRRGs) remains unexplored.
Methods: Analysis of pancreatic ductal adenocarcinoma (PDAC) datasets, including transcription profiles, clinical data, and tissue microarrays, was conducted to evaluate PRRG1 expression and its clinical relevance.

Acrolein (ACR) present in vivo and in vitro can damage proteins and DNA, linking it to various chronic diseases. In this paper, ergothioneine (EGT), abundant in edible mushrooms, has been studied for its ability to trap ACR and its reaction pathway with ACR at high temperatures using ultraperformance liquid chromatography-mass spectrometry (UPLC-MS/MS). We synthesized the adducts (EGT-ACR-1 and EGT-ACR-2), elucidating their structure and reaction site through HRMS and nuclear magnetic resonance.
