Publikováno v: Food and Chemical Toxicology. 124:128-138

Aflatoxins (AFs) are toxic secondary metabolites of the fungi Aspergillus flavus, A. parasiticus and A. nomius. The fungi produce these AFs in cereals, oilseeds and spices. AFs have damaging effects on all organisms, including humans, and their sympt

Mutagens and Carcinogens Called Aflatoxins and Their Hydroxylated Metabolites in Food for Domestic Cats

Autor: Francisco Rojo-Callejas, Silvia Ruiz-Velasco, Magda Carvajal-Moreno, Gomez-Carrion A, Fuentes-Daza S, Martinez-Ruiz Nc

Publikováno v: Biochemistry & Analytical Biochemistry.

Aflatoxins (AFs) in cat food are a serious threat to cat health. The exposure of cats to AFs can cause damage depending on the exposure time and dosage, as well as the diet, nutritional state, age and sex of the cat. The first acute effect of AFs is

The Effect of Maize Germ on the Presence of Aflatoxins in Corn Flours Treated with a Thermo-Alkaline Process

Autor: Silvia Ruiz-Velasco, Lineth J. Vega-Rojas, Francisco Rojo-Callejas, Isela Rojas-Molina, Magda Carvajal-Moreno, Mario E Rodriguez Garcia

Publikováno v: Journal of Microbial & Biochemical Technology.

Background: Aflatoxins are important and frequent teratogens, mutagens and carcinogens of maize, and the germ of the maize seed has linoleic acid, which can control aflatoxins. An aflatoxin analysis of maize flours with and without germ can show the

Aflatoxins in Natural Peanuts (Arachis hypogaea L.) of Mexico: Validation of the Biochemical Methods for Extraction and Quantification

Autor: Silvia Ruiz-Velasco, Magda Carvajal-Moreno, Francisco Rojo-Callejas, Jose Rodrigo Alvarado-Hernández

Publikováno v: Journal of Plant Biochemistry & Physiology.

The peanut (Arachis hypogaea L.) is frequently contaminated with aflatoxins (AFs). Aflatoxins are toxic secondary metabolites – bifuran coumarins – produced by the fungi Aspergillus spp. AFs cause damage in animals and humans, including bleeding,
