Confirmatory Tests for Aflatoxin B1

Journal of AOAC INTERNATIONAL, 1964
Abstract Three confirmatory tests have been devised to identify aflatoxin B±. Portions of the isolated toxin are treated with formic acid-thionyl chloride, acetic acid-thionyl chloride, and trifluoroacetic acid, respectively, and aliquots of the three fluorescent reaction products are spotted on thin-layer chromatography plates ...

Early‐Onset Digestive System Cancers: Risk Factors and Clinicopathological and Molecular Features Across Organ Sites

Cancer Science, Volume 117, Issue 5, Page 1223-1234, May 2026.
Shared risk factors, clinical features, and tumor characteristics across multiple early‐onset cancer types are shown in this Graphical Abstract. Integrative approaches combining molecular pathology, oncology, and population sciences offer opportunities to clarify underlying mechanisms and help us develop preventive strategies for early‐onset cancers ...

Mechanobiology in Stem Cell‐Based Bioprinting

Cell Proliferation, Volume 59, Issue 5, May 2026.
Mechanobiology in stem cell‐based bioprinting is an emerging field that bridges the mechanical conditions of the bioprinting process with the regulation of stem cell behaviour for engineering living tissues. Stresses encountered during bioprinting, together with the mechanical properties of bioinks, play a critical role in regulating stem cell ...

Voltammetric Determination of Aflatoxin B1

Procedia Chemistry, 2014
AbstractFor the first time the possibility of voltammetry used for the determination of aflatoxin B1 on a glassy carbon electrode was shown. The effect of pH of a supporting electrolyte on the analytical signal of aflatoxin B1 has been investigated and it was shown that there is a more pronounced peak with a maximum current at pH of 5.33.

Updated safety evaluation of the food enzyme catalase from the non‐genetically modified Aspergillus tubingensis strain AE‐CN

EFSA Journal, Volume 24, Issue 5, May 2026.
Abstract The food enzyme catalase (hydrogen‐peroxide:hydrogen‐peroxide oxidoreductase; EC 1.11.1.6) is produced with the non‐genetically modified Aspergillus tubingensis strain AE‐CN by Amano Enzyme Inc. The food enzyme is intended to be used in seven food manufacturing processes.

Early detection of the aflatoxin B1 mutational fingerprint: A diagnostic tool for liver cancer

Molecular & Cellular Oncology, 2017
Using duplex-consensus sequencing technology, we recently identified the characteristic high-resolution mutational spectrum of the liver carcinogen aflatoxin B1 in a mouse model, many months before aflatoxin-induced tumors are detectable.

Assessment of Aflatoxin B1 and Ochratoxin A Levels in Rice Produced in Khuzestan and Kohgiluyeh and Boyer Ahmad Provinces, Iran

Journal of Mazandaran University of Medical Sciences, 2018
Background and purpose: Contamination of food materials such as rice to mycotoxins (aflatoxin B1 and Ochratoxin A) is a major health concern. This causes more concerns especially in countries that rice is the main food.

The occurrence and human health risk assessment of total and aflatoxin B1 in selected food commodities in Bhutan

Scientific Reports
Aflatoxins are mycotoxins that contaminate staple foods globally and pose a significant health risk. To the best of our knowledge, information on the occurrence of aflatoxins in Bhutanese diets is scarce. This study aimed to estimate the aflatoxin levels
