Method development and validation for the simultaneous determination of 21 antiviral drugs by ultra-high performance liquid chromatography-tandem mass spectrometry in chicken muscle and liver.

The recent unauthorization of antiviral drugs in food-producing animals according to Commission Delegated Regulation (EU) 2022/1644 have increased the need for food control laboratories to develop analytical methods and perform official controls. In this work, a simple and fast analytical methodology was developed for the simultaneous determination of 21 antiviral drugs in chicken muscle and liver by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Chromatographic separation was achieved by an HILIC BEH amide column; followed by detection with a electrospray ionization source in positive and negative modes.

Bacterial and fungal diversity and species interactions inversely affect ecosystem functions under drought in a semi-arid grassland.

Extreme climatic events, such as drought, can significantly alter belowground microbial diversity and species interactions, leading to unknown consequences for ecosystem functioning. Here, we simulated a drought gradient by removing 30 %, 50 %, and 70 % of precipitation in a semi-arid grassland over five years. We assessed the effects of drought on bacterial and fungal diversity, as well as on their species interactions.

A genomic variation map provides insights into potato evolution and key agronomic traits.

Hybrid potato breeding based on diploid inbred lines is transforming the way of genetic improvement of this staple food crop, which requires a deep understanding of potato domestication and differentiation. Here, we resequenced 314 diploid wild and landrace accessions to generate a variome map of 47,203,407 variants. Using the variome map, we discovered the reshaping of tuber transcriptome during potato domestication, characterized genome-wide differentiation between landrace groups Stenotomum and Phureja, and identified a jasmonic acid biosynthetic gene possibly affecting tuber dormancy period.

This requires knowledge integration and collaboration across the human, animal, vector, and environmental health domains, aligning with the One Health approach. Despite the importance of a One Health approach, engaging stakeholders from each domain remains challenging.

Zinc absorption from maize-based meals enriched with edible house crickets: a randomized crossover stable-isotope study in Kenyan pre-school children.

Edible insects have been proposed as a novel and sustainable source of protein and other essential nutrients for human consumption but nutrient absorption efficiency is still uncertain. We investigated zinc absorption from house crickets (Acheta domesticus) in a single-center and single-blinded cross-over study with children aged 24-36 months old in Kenya from September-November 2021. For this, children were randomized to consume two different experimental meals labeled with stable isotopes of zinc (Zn) at two different days, separated by a wash-out period of one month.

Advances in digital camera-based phenotyping of Botrytis disease development.

Botrytis cinerea is an important generalist fungal plant pathogen that causes great economic losses. Conventional detection methods to identify B. cinerea infections rely on visual assessments, which are error prone, subjective, labor intensive, hard to quantify, and unsuitable for artificial intelligence (AI) and machine learning (ML) applications.

A proposed screening strategy for evaluating the genotoxicity potential of botanicals and botanical extracts.

Botanicals have long been used to promote health and treat diseases, but the safety of many currently marketed botanicals has not been adequately evaluated. Given the chemical complexity of botanicals, which often contain numerous unknown constituents, and their widespread use, comprehensive toxicity assessments are needed. The Botanical Safety Consortium was established to address this challenge.

Thrips tabaci is the main thrips species affecting onion and related species. It is a cryptic species complex comprising three phylogenetic groups characterized by different reproductive modes (thelytoky or arrhenotoky) and host plant specialization. Thrips tabaci populations vary widely in genetic diversity, raising questions about the factor(s) that drive this diversity.

Vegetation-climate feedbacks across scales.

Vegetation is often viewed as a consequence of long-term climate conditions. However, vegetation itself plays a fundamental role in shaping Earth's climate by regulating the energy, water, and biogeochemical cycles across terrestrial landscapes. It exerts influence by consuming water resources through transpiration and interception, lowering atmospheric CO concentration, altering surface roughness, and controlling net radiation and its partitioning into sensible and latent heat fluxes.

However, despite its historical and nutritional significance, its chemical composition remains poorly understood. To deepen the understanding of the of Rumex sanguineus composition, an in-depth analysis using non-targeted, mass spectrometry-based metabolomics was performed.

Quantitative interpretation and modelling of continuous nonprotein respiratory quotients.

The Respiratory Exchange Ratio (RER), which is the ratio of total carbon dioxide produced over total oxygen consumed, serves as a qualitative measure to determine the substrate usage of a particular organism on the whole-body level. Quantification of RER by its direct conversion into %Glucose (%G) and %Lipid oxidation (%L) at a given timepoint can be done by utilizing nonprotein respiratory quotient tables. These tables, however, are limited to specific increments, and intermediate RER values are not covered by these tables.

Multi-Omics analysis reveals the sensory quality and fungal communities of Tibetan teas produced by wet- and dry-piling fermentation.

Ya'an Tibetan tea, a dark tea with a rich historical heritage, is typically processed using two primary piling fermentation methods: wet piling with rolled leaves (moisture content around 60%) and dry piling with sun-dried or baked green tea leaves (moisture content below 30%). This study employed sensory evaluation, targeted and non-targeted metabolomics, and fungal Internal Transcribed Spacer (ITS) sequencing to investigate changes in quality components and fungal composition in Tibetan tea processed by both wet and dry-piling methods. The results revealed that 3,7-Dimethyl-1,5,7-octatriene-3-ol and D-limonene were identified as key volatile metabolites contributing to the aroma variations between the dry and wet-piled teas.
