Field evaluation of maize genotypes for resistance to pre-harvest Aspergillus ear rot and aflatoxin contamination under natural inoculation in Eastern and Northern Tanzania [PDF]

Frontiers in Plant Science
Maize, a staple for billions of people, is highly vulnerable to aflatoxin contamination caused by Aspergillus flavus. Aflatoxins pose serious threats and risks to food safety, public health, and trade.

Low-dose ethanol increases aflatoxin production due to the adh1-dependent incorporation of ethanol into aflatoxin biosynthesis

iScience, 2023
Summary: Aflatoxins are toxic secondary metabolites produced by some aspergilli, including Aspergillus flavus. Recently, ethanol has attracted attention as an agent for the control of aflatoxin contamination.

Aflatoxin exposure among children of age 12–59 Months in Butajira District, South-Central Ethiopia: a community based cross-sectional study

BMC Pediatrics, 2022
Background The continued provision of safe food, free of aflatoxin remains a huge challenge in developing countries. Despite several favourable climatic conditions that facilitate aflatoxin contamination in Ethiopia, there is little information showing ...

Effect of non-aflatoxigenic strains of Aspergillus flavus on aflatoxin contamination of pre-harvest peanuts in fields in China

Oil Crop Science, 2021
Aflatoxin contamination of peanuts is one of the most concerns in peanut production in China. Applying non-aflatoxigenic Aspergillus flavus strains, based on competitive exclusion, has been proved to be a promising strategy to reduce aflatoxin ...

Detection of Aflatoxins B1 in Maize Grains Using Fluorescence Resonance Energy Transfer

Applied Sciences, 2020
Aflatoxins are secondary metabolites of Aspergillus flavus and Aspergillus parasiticus. These fungal species are the most dangerous and common toxin group causing food contamination. Aflatoxin has high toxicity and can cause cancer to humans and animals.

TP53 R249S mutation in hepatic organoids captures the predisposing cancer risk

Hepatology, EarlyView., 2022
The systematic approach in elucidating the gain‐of‐function (GOF) roles of TP53 mutations in early liver carcinogenesis. Unique downstream targets of TP53 L3 mutations were identified from chormatin immunoprecipitation sequencing in HCC cell lines, followed by a series of validation assays to substantiate the exclusive transcriptional regulations ...

Controlling aflatoxin in maize: The effects of varieties, packaging materials, and agroecological zones

Heliyon, 2023
Contamination of crops by aflatoxin is rampant in warm regions worldwide, including Sub-Sahara Africa. Contamination of maize and other foodstuffs with aflatoxin seriously threatens the health of humans and animals. The experimental design used was 2 × 2

Determination of the Aflatoxins [PDF]

Nature, 1964
Top of pageAbstract WE report a new chemical method for determining the aflatoxins and, in particular, aflatoxin B1. Previous methods have depended on the measurement of fluorescence1,2 and are subject to certain errors, for example, quenching by impurities.
