Enzyme-linked immunosorbent assay (ELISA) represents a bioanalytical strategy frequently used for rapid screening of mycotoxin deoxynivalenol (DON) in cereals and derived products. Due to a considerable affinity of some anti-DON antibodies to structurally similar DON metabolites, such as DON-3-glucoside (DON-3-Glc) and 3-acetyl-DON (3-ADON), a significant overestimation of DON concentrations may occur. A validation study of six commercial DON-dedicated ELISA kits, namely Ridascreen DON, Ridascreen FAST, DON, DON EIA, AgraQuant DON Assay, Veratox 5/5, and Veratox HS was carried out on wheat, barley, and malt matrices. Performance characteristics of all tested ELISAs were determined using aqueous solutions of DON, DON-3-Glc, and 3-ADON analytical standards, further with extracts of artificially spiked blank cereals, and finally with matrix-matched standards of all three compounds. In the final phase, the accuracy of data was assessed through a comparison of DON concentrations determined by particular ELISAs and reference ultra-high-performance liquid chromatography-tandem mass spectrometry method. For this purpose, both quality control materials and a comprehensive set of naturally and artificially contaminated samples of wheat, barley, and malt were analyzed. High cross-reactivities were proved for both DON-3-Glc and 3-ADON in the majority of examined assays, and moreover, a considerable contribution of some matrix components to overestimation of DON results was confirmed.

'Why Don't We Get Counselling?': Comparing NICE Guidelines for Morphological and Genetic Cancer Risk Diagnoses.
Cancer Med
January 2025
Nuffield Department of Primary Care Health Sciences, University of Oxford, Oxford, UK.
Background: In the UK's National Health Service (NHS), there is specific psychosocial care offered to people with genetic cancer risk conditions but not morphological cancer risk conditions. As researchers develop new ways to diagnose morphological risk conditions, including precancers and in situ cancers, it is important to consider the psychosocial care that those diagnosed might require.
Objectives: This study compares the National Institute for Health and Care Excellence's guidelines for BRCA1/2, which are genetic risk conditions, and Barrett's oesophagus (BO), a morphological risk condition.
Obesity and the Importance of Breathing.

Obesity is a complex and non-communicable disease with a pandemic entity. Currently, multiple causes can lead to obesity, and it is not always easy to create a direct relationship between physical inactivity, poor quality of nutrients consumed, and calculation of excess calories. Among the associated comorbidities, obesity creates a dysfunctional environment of respiratory rhythms at the central and peripheral levels, with functional, morphological, and phenotypic alteration of the diaphragm muscle.

Background: Families residing in disadvantaged communities encounter inequalities that restrict their engagement in physical activity. Family-based interventions and health coordinators have been proposed as promising approaches to encourage physical activity among parents and children. However, there is a paucity of knowledge regarding family experiences of such programmes and the ways health coordinators facilitate continued participation in programmes delivered in disadvantaged communities.

Phosphorylation of N-glycans in the brain: The case for a non-canonical pathway?

Asparagine-linked glycosylation (N-glycosylation) is a common co- and post-translational modification that refers to the addition of complex carbohydrates, called N-linked glycans (N-glycans), to asparagine residues within defined sequons of polypeptide acceptors. Some N-glycans can be modified by the addition of phosphate moieties to their monosaccharide residues, thus forming phospho-N-glycans (PNGs). The most prominent such carbohydrate modification is mannose-6-phosphate (M6P) which plays a well-established role in trafficking of acid hydrolases to lysosomes.
