Abstract

Aflatoxins (AFs) are hepatogenic, teratogenic, imunosuppressive, and carcinogenic fungal metabolites found in feeds, nuts, wine-grapes, spices, and other grain crops. Humans are exposed to AFs via consumption of mycotoxin-contaminated foods. This study aimed to determine the prevalence of AF contamination in powdered red peppers sold in Sanliurfa. A total of 42 samples were randomly collected from retail shops, supermarkets, open bazaars, and apiaries and examined for the occurrence and levels of AFB1, AFB2, AFG1, and AFG2 toxins. AFs were determined by using an HPLC system after pre-separation utilizing immunoaffinity columns. AFs levels were below 2.5 μg/kg in 16 samples, between 2.5 and 10 μg/kg in 13 samples while 13 samples had AFs higher than the tolerable limit (10 μg/kg) according to the regulations of Turkish Food Codex and European Commission. The occurrence of AF fractions during powdered red pepper processing steps was also evaluated. According to the results obtained in this study, it was found that the highest AF accumulations in powdered red peppers start during perspiration and final drying of the products processed on soil contacted surfaces while there was no limit exceeding aflatoxin contamination in the samp...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
