objective: fusarium species are prevalent contaminants of foodstuffs and agricultural crops.  they produce fumonisins, which are carcinogenic mycotoxins. the present study has evaluated maize and wheat samples from ten provinces in iran that were contaminated with fusarium species. special attention was paid to the ability of the isolates to produce fumonisin b1 (fb1) as a public health hazard....

Levels of mycotoxins produced by Fusarium species in genetically modified (GM) and near-isogenic maize, were determined using multi-analyte, microbead-based flow immunocytometry with fluorescence detection, for the parallel quantitative determination of fumonisin B1, deoxynivalenol, zearalenone, T-2, ochratoxin A, and aflatoxin B1. Maize varieties included the genetic events MON 810 and DAS-591...

Fumonisin B1 (FB1) is the most abundant of the fumonisin mycotoxins, mainly produced in corn by fungi of the genus Fusarium. FB1 has been shown to be hepatocarcinogenic and nephrocarcinogenic in animals. Contamination of corn with FB1 was assayed in samples collected from Mazandaran Province, situated on the Caspian littoral of Iran, in September 2000. In this survey, 38 corn samples were analy...

BACKGROUND Fumonisin B1 (FB1), fumonisin B2 (FB2), and overall mycotoxins feed contamination may cause several effects on crops production and animal health. The contamination occurred predominantly in corn and corn-based foods and feeds. AIMS This survey intends to provide the occurrence of fumonisins in swine and equine mixed feeds in Portugal, making an overview from 2007 to 2010. METHOD...

Apolipoprotein E (apoE) is a key transporter of the cholesterol and phospholipids required for membrane synthesis and nerve growth. We now report a virtual absence in apoE knock-out (KO) mice of normal nerve growth factor (NGF)-driven compensatory sprouting of undamaged cutaneous nociceptive nerves. In contrast, NGF-independent regeneration of crushed axons was unaffected. Essentially similar r...

results mycoflora profiles of fresh and stored rice grains showed that aspergillus species (37.3%, 40.7%) were the predominant fungal agents, followed by fusarium (21.6%, 16.2%), mucor (19.6%, 16.7%) and rhizopus (9.8%, 11.1%), respectively. in hplc analysis, most of the rice samples (96.7%) collected were found to be positive for fb1 with mean levels ranging from not detected to 56.2 mg/kg for...

Maize grain samples (n=15) collected during the autumn of 2002 were analyzed for the presence of moulds and mycotoxins fumonisin B1 (FB1), fumonisin B2 (FB2), zearalenone (ZEA), and ochratoxin A (OTA). Mycological analysis showed that all samples were contaminated with Fusarium spp. and Penicillium spp., while Aspergillus spp. were found in 5 samples. F. proliferatum and F. verticilloides, the ...
