Liver cancer is an emerging global health issue, with rising incidence in both the United States and the economically developing world. Although Guatemala experiences the highest rates of this disease in the Western hemisphere and a unique 1:1 distribution in men and women, few studies have focused on this population. Thus, we determined the prevalence and correlates of aflatoxin B1 (AFB1) expo...

An experiment was conducted to determine the efficacy of mycotoxin sequestering agents for binding or degrading aflatoxin B1 (AFB1) and deoxynivalenol (DON) by an in vitro method. Ten toxin binder products including 5 bentonite clays (bentonite A, B, C, D, and E), 2 cellulose products (cellulose A and B), a yeast cell wall, an activated charcoal, and a mixture product containing minerals, micro...

Both hepatitis B virus (HBV) and aflatoxin B1 (AFB1) exposure can cause liver damage as well as increase the probability of hepatocellular carcinoma (HCC). To investigate the underlying genetic changes that may influence development of HCC associated with HBV infection and AFB1 exposure, HCC patients were subdivided into 4 groups depending upon HBV and AFB1 exposure status: (HBV(+)/AFB1(+), HBV...

Aflatoxins are natural secondary metabolites produced by some moulds (mainly Aspergillus flavus and Aspergillus parasiticus) and are contaminants of agricultural commodities in the field particularly in critical temperature and humidity conditions before or during harvest or because of inappropriate storage (Rustom, 1997; Sweeney & Dobson, 1998). Aflatoxins B1 (AFB1) and B2 (AFB2), producted by...

Alflatoxin B1 (AFB1) is the most hepatotoxic and : Background hepatocarcinogenic of the aflatoxins and occurs as a contaminant in a variety of foods. The toxicity of AFB1 has been shown to be associated with a wide range of pathological events, such as enhanced apoptosis and oxidative events. Currently there is no treatment for mycotoxin exposure. The aim of this study was to evaluate the poten...

Aflatoxin B2a (AFB2a) antiserum has been previously used in an enzyme-linked immunosorbent assay (ELISA) for the quantitation of AFB1 and AFB2a. The present investigation examined the reactivity of the antiserum toward those adducts and metabolites of AFB1 believed to play a major role in aflatoxicosis and carcinogenesis. 2,3-Dihydro-2-(N7-guanyl)-3-hydroxyaflatoxin B1 (AFB1-N7-Gua), the putati...

Each of the risk factors for human liver cancer (aflatoxin exposure, hepatitis B virus-associated liver injury, p53 loss, p53ser249 mutation, and male sex) also increases the incidence of hepatocellular carcinoma (HCC) in mouse models of hepatocarcinogenesis. Neonatal mice, partially hepatectomized adult mice, and p53-deficient mice each have a higher hepatocyte proliferation rate, are less abl...

aflatoxin is one of the most hazardous mycotoxins injurious to both humans and animals. aflatoxin contamination of crops is a serious economic loss inflicted upon agriculture, food and animal industry throughout the entire world. in nature, there are microorganisms able to alleviate aflatoxin contamination in crop products. in this work, the effects of four strains of bacillus subtilis in reduc...
