Recently, deoxynivalenol-3-sulfate (DON-3-sulfate) was proposed as a major DON metabolite in poultry. In the present work, the first LC-MS/MS based method for determination of DON-3-sulfate, deepoxy-DON-3-sulfate (DOM-3-sulfate), DON, DOM, DON sulfonates 1, 2, 3, and DOM sulfonate 2 in excreta samples of chickens and turkeys was developed and validated. To this end, DOM-3-sulfate was chemically...

Deoxynivalenol (DON) is a common Fusarium toxin in poultry feed. Chickens are more resistant to the adverse impacts of deoxynivalenol (DON) compared to other species. In general, the acute form of DON mycotoxicosis rarely occurs in poultry flocks under normal conditions. However, if diets contain low levels of DON (less than 5 mg DON/kg diet), lower productivity, impaired immunity and higher su...

dissolved organic nitrogen (don) can react with disinfectants to produce numerous disinfectionbyproducts (dbps), particularly nitrogen-containing dbps (n-dbps), and produce serious adverse effectson public health. widely used biological processes in drinking water treatment can increase don in effluents,and enhance these ill effects. this study investigated don in a full-scale two-stage ozonati...

Two experiments were conducted to characterize the progression of deoxynivalenol (DON)-induced growth suppression and to investigate algae-modified montmorillonite clay (AMMC) as a means to alleviate the effects of DON in nursery pigs. In both experiments, naturally DON-contaminated wheat was used to produce diets with desired DON levels. In Exp. 1, 280 barrows and gilts (10.0 ± 0.2 kg BW) were...

Background Deoxynivalenol (DON) is one of the most common mycotoxins found in cereal grains. Objective The purpose of this survey was determination of difference between DON fungal toxin pollution level in raw wheat flour and bread. Methods: In this In the present analytical-cross-sectional study, to determine DON level, 44 subjects were random samplings of wheat, bread and flour (Lavash and ...

چکیده سیزده جدایه fusarium graminearum عامل بلایت فوزاریومی سنبله گندم، جمع آوری شده از مناطق شمالی کشور (گرگان، ساری، کلاردشت و مغان) جهت بررسی میزان تولید توکسین don))deoxynivalenol به محیط کشت جو منتقل شدند و استخراج توکسین به دو روش ( ueno, 1987و hongxiang et al., 2009) صورت گرفت. مقدار توکسین تولید شده در جدایه ها با آزمون الایزا مورد بررسی قرار گرفت و نتایج نشان داد که تمامی نمون...

This paper empirically examines commercialization of university faculty inventions through startup firms from 1994 through 2008. Using data from the Association of University Technology Managers and the 2010 NRC doctoral rankings, our research reveals several findings. We find that university entrepreneurship is more common in bad economic times and that engineering department quality and biolo...

[1] Storm event patterns of dissolved organic nitrogen (DON) were studied for multiple events across four catchments (1.6–696 ha) in a forested, glaciated watershed in western New York State. Highest concentrations of DON in the watershed were recorded for litter leachate followed by throughfall. Storm event concentrations of DON consistently peaked at or before peak discharge while dissolved o...

Co-occurrence of deoxynivalenol (DON) with other DON derivatives/metabolites and other Fusarium toxins, including zearalenone, nivalenol and as well as other mycotoxins (e.g. fumonisins) is frequently observed in food and feed. DON-3beta-glucopyranoside (DON-3-glucoside) was described as detoxification product of DON in wheat. This mycotoxin conjugate was observed in maize, barley, malt, beer a...

Two experiments were conducted to evaluate potential detoxifying agents on growth of nursery pigs fed deoxynivalenol (DON)-contaminated diets. Naturally DON-contaminated wheat (6 mg/kg) was used to achieve desired DON levels. In a 21-d study, 238 pigs (13.4 ± 1.8 kg BW) were used in a completely randomized design with a 2 × 2 + 1 factorial arrangement. Diets were: 1) Positive control (PC; < 0.5...
