Aflatoxin contamination in dried fruits and nuts in Bangladesh: Occurrence, dietary exposure, and health risk assessment

JSFA reports, EarlyView.
Abstract Background Dried fruits and nuts are widely consumed for their desirable sensory qualities and high nutritional value, providing essential nutrients such as proteins, healthy fatty acids, potassium, dietary fiber, and bioactive compounds. However, they are highly susceptible to aflatoxin contamination, particularly in humid tropical regions ...

l-Threonine and its analogue added to autoclaved solid medium suppress trichothecene production by Fusarium graminearum [PDF]

, 2017
Fusarium graminearum produces trichothecene mycotoxins under certain nutritional conditions. When L-Thr and its analogue L-allo-threonine were added to brown rice flour solid medium before inoculation, trichothecene production after 4 days of incubation ...

Pro-Inflammatory Effects of NX-3 Toxin Are Comparable to Deoxynivalenol and not Modulated by the Co-Occurring Pro-Oxidant Aurofusarin

Microorganisms, 2020
The type A trichothecene NX-3, produced by certain Fusarium graminearum strains, is similar to the mycotoxin deoxynivalenol (DON), with the exception that it lacks the carbonyl moiety at the C-8 position.

White and whole wheat flour breads: composition and simultaneous exposure to group B trichothecenes

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The study aimed to determine the profile of group B trichothecenes (TCTBs), to estimate the daily exposure to them and to evaluate the relationship with the composition of different types of sliced wheat bread. A method for simultaneous determination of the TCTBs (deoxynivalenol (DON), 3‐acetyl‐deoxynivalenol, 15‐acetyl ...

Establishment of a Human Cell‐Based In Vitro Test System for Investigating and Evaluating Cytotoxic and Immunomodulatory Effects of Indoor Mold

Environmental Toxicology, EarlyView.
ABSTRACT Mold growth in damp indoor environments is a widespread problem associated with respiratory health effects, though causal mechanisms remain incompletely understood. We established a human cell‐based in vitro test system using bronchial epithelial cells (NuLi‐1) and macrophages (THP‐1) to assess inhalation toxicity and immunomodulatory effects ...

Data_Sheet_1_Regulatory mechanism of trichothecene biosynthesis in Fusarium graminearum.pdf

, 2023
Among the genes involved in the biosynthesis of trichothecene (Tri genes), Tri6 and Tri10 encode a transcription factor with unique Cys2His2 zinc finger domains and a regulatory protein with no consensus DNA-binding sequences, respectively.

Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

Integrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

Fumonisins, Trichothecenes and Zearalenone in Cereals [PDF]

International Journal of Molecular Sciences, 2008
Fumonisins are phytotoxic mycotoxins which are synthesized by various species of the fungal genus Fusarium such as Fusarium verticillioides (Sacc.) Nirenberg (ex F.moniliforme Sheldon) and Fusarium proliferatum. The trichothecene (TC) mycotoxins are secondary metabolites produce by species that belong to several fungal genera, especially Fusarium ...

Reduced Toxicity of Trichothecenes, Isotrichodermol, and Deoxynivalenol, by Transgenic Expression of the Tri101 3-O-Acetyltransferase Gene in Cultured Mammalian FM3A Cells

Toxins, 2019
In trichothecene-producing fusaria, isotrichodermol (ITDol) is the first intermediate with a trichothecene skeleton. In the biosynthetic pathway of trichothecene, a 3-O-acetyltransferase, encoded by Tri101, acetylates ITDol to a less-toxic intermediate ...
