  • Dictary exposure and risk assessment of mycotoxins in thyme and thyme-based products marketed in Lebanon 
    Koaik, Lara (Notre Dame University-Louaize, 2022-02)
    Thyme is a Mediterranean herb widely used worldwide. However, it is produced in areas of high humidity and temperature which is favorable conditions for mold growth and mycotoxins production which pose public health risk. In Lebanon, no studies have been done to investigate aflatoxin B1 (AFB1) and ochratoxin A (OTA) contamination in thyme and thyme-based products. This study aimed at evaluating the incidence of AFB1 and OTA in those products, related dietary exposure and cancer risk for regular and high consumption. A total of 160 samples of thyme and thyme-based products were collected and ...
  • Effect of Mycotoxins on spermatogonial stem cells 
    Fayjaloun, Salma (Notre Dame University-Louaize, 2019)
    Fusarium mycotoxins are natural contaminants of various commodities representing significant problem worldwide. Since beauvericin (BEA), one of the fusarium toxins, represents a major concern because of its potential toxicity in humans and animal health, and its high presence in feed and food commodities, the present study was carried out to evaluate the effect of BEA on cell viability, proliferation, morphology and gene expression using spermatogonial stem cells (SSCs). First, SSCs were isolated from fresh sheep testis under aseptic technique. Isolated SSCs were cultured for 36 hours at 5% CO2. ...
