Identification and Quantification of Fumonisin A1, A2, and A3 in Corn by High-Resolution Liquid Chromatography-Orbitrap Mass Spectrometry

Toxins, 2015
Three compounds, hypothesized as fumonisin A1 (FA1), fumonisin A2 (FA2), and fumonisin A3 (FA3), were detected in a corn sample contaminated with mycotoxins by high-resolution liquid chromatography-Orbitrap mass spectrometry (LC-Orbitrap MS).

Cancer Stem Cells Shift Metabolite Acetyl‐Coenzyme A to Abrogate the Differentiation of CD103+ T Cells

Advanced Science, Volume 13, Issue 8, 9 February 2026.
Lei et al. demonstrate that cancer stem cells (CSCs) play a pivotal role in impairing the differentiation of CD103+ T cells in patients with non‐small‐cell lung cancer. The key mechanism involves CSC‐derived acetyl‐CoA, which disrupts CD103+ T cell differentiation by sequentially inducing acetylation and ubiquitination of the Blimp‐1 protein. Targeting

Determination of fumonisin B1 levels in body fluids and hair from piglets fed fumonisin B1-contaminated diets

Food and Chemical Toxicology, 2017
The levels of fumonisin B1 (FB1) residues in plasma, urine, feces and hair from 24 piglets fed FB1-contaminated diets containing 3.1, 6.1 or 9.0 μg FB1.g-1 for 28 days were determined using liquid chromatography coupled to mass spectrometry (LC-MS/MS). The levels of FB1 in plasma, urine, feces and pooled hair (n = 3) samples varied from 0.15 to 1.08 μg.

Yeast‐Based Biotechnology for Civilian Security

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Yeasts constitute robust and versatile eukaryotic platforms for biotechnological applications relevant to civilian security. Both native and genetically engineered yeast systems enable sensitive detection of chemical and biological hazards, effective removal of metals and organic pollutants, and detoxification of mycotoxins.

Protective Roles of Prebiotics and Probiotics Against Environmental Pollutant‐Induced Toxicities: A Systematic Review of Animal Studies

Molecular Nutrition &Food Research, Volume 70, Issue 1, January 2026.
Pollutant‐induced epithelial damage also leads to a cascade of harmful effects, including reduced mucus secretion, decreased luminal pH, and enhanced absorption of toxins. These changes contribute to oxidative stress (↑ malondialdehyde (MDA); ↓ superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), glutathione peroxidase (GPx), and heightened ...

Simulation of Fungal-Mediated Cell Death by Fumonisin B1 and Selection of Fumonisin B1–Resistant (fbr) Arabidopsis Mutants [PDF]

The Plant Cell, 2000
Fumonisin B1 (FB1), a programmed cell death-eliciting toxin produced by the necrotrophic fungal plant pathogen Fusarium moniliforme, was used to simulate pathogen infection in Arabidopsis. Plants infiltrated with 10 microM FB1 and seedlings transferred to agar media containing 1 microM FB1 develop lesions reminiscent of the hypersensitive response ...

The Effect of Mustard Powder Percentage on the Physicochemical, Microbial Load, and Sensory Analysis of Artisanal Ethiopian Cottage Cheese

Journal of Food Processing and Preservation, Volume 2026, Issue 1, 2026.
Cottage cheese quality and shelf life are global challenges, but natural preservatives like mustard seed powder are used due to their antioxidant and antimicrobial properties. This study examines different percentages of mustard powder (C [0%], B1 [0.05%], B2 [0.1%], and B3 [0.15%]) and storage times (T0 [0], T1 [4], T2 [8], T3 [12], and T4 [15] days ...

Advice on animal and public health risks of insects reared on former foodstuffs as raw material for animal feed

Food Risk Assess Europe, Volume 4, Issue 1, January 2026.
Abstract In the coming decades, there is expected to be a sharply increased demand for dietary proteins for humans and animals. As a result, there is an increasing focus on reared insects as a new source of protein. According to the Ministry of Agriculture, Nature and Food Quality (LNV), the use of food chain residual flows such as former foodstuffs as

Validation of a biochip array technology for multi-mycotoxins screening in Rice and other cereals

Food Chemistry Advances
Cereal grains are widely cultivated agricultural commodities, and they constitute a key source of energy. However, many of them are affected by fungal contamination, and consequently, by the presence of mycotoxin. The development of monitoring techniques
