Emerging Issues on Tropane Alkaloid Contamination of Food in Europe

Toxins, 2023
The occurrence of tropane alkaloids (TAs), toxic plant metabolites, in food in Europe was studied to identify those TAs in food most relevant for human health. Information was extracted from the literature and the 2016 study from the European Food Safety

From nature to nanoscale: advances, challenges, and preclinical translation of nanofiber drug delivery systems containing plant‐derived active ingredients

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Since the early 1960s, nanotechnology has been a critical area of science, allowing for the development of sophisticated nanomaterials. Nanofibers, one of the most widely used nanotechnological drug delivery systems, have emerged as a highly versatile platform within modern pharmaceutical sciences.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Knocking Out Two Polyphenol Oxidase Genes Significantly Improves Recombinant Protein Purification in Nicotiana benthamiana

Plant Biotechnology Journal, EarlyView.
ABSTRACT Efficient purification remains a key technical challenge affecting the recovery efficiency of recombinant proteins in plant‐based systems. Complex metabolites, particularly polyphenols, often cause recombinant protein aggregation during purification.

Unravelling Mechanisms of Acquired Drought Tolerance by Priming in Tomato Using Integrative Multi‐Omics Phenotypic Analysis

Plant Biotechnology Journal, EarlyView.
ABSTRACT The escalating frequency and intensity of recent droughts threaten global crop production and food security. Although drought priming is crucial for plant drought resilience, the mechanisms imparting drought stress memory remain poorly understood, especially in crops such as tomato. This study elucidates the mechanisms of drought stress memory

Citrus depressa peel extract and its polymethoxyflavones mitigate acetaminophen‐induced chronic liver injury in mice through antioxidant activation, epigenetic regulation, and gut microbiota modulation

Journal of the Science of Food and Agriculture, Volume 106, Issue 13, Page 7629-7642, October 2026.
Abstract BACKGROUND Preventing chronic liver damage is essential for maintaining overall health and reducing the risk of serious liver diseases. Acetaminophen (APAP) overdose can lead to severe liver damage due to oxidative stress, and citrus fruits are rich in bioactive compounds that may have health benefits.

Exploring Cervical Cancer‐Associated Vaginal and Cervical Microbiota via 16S rRNA Sequencing

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
This 16S sequencing study identified a dysbiotic cervical microbiota (increased diversity, reduced Lactobacillus, enriched Prevotella) specifically linked to high‐risk HPV infection. These microbial alterations, shaped by the HPV‐driven microenvironment, offer novel targets for biomarkers and mechanistic research in cervical carcinogenesis.
