background: deoxynivalenol (don) is a mycotoxin produced mainly by fusarium graminearum in grains such as wheat and maize. the aim of this study was to evaluate the inhibitory effects of citrus flavanones including, naringin (nar), hesperidin (hes), and neohesperidin (neo) on deoxynivalenol production using response surface methodology (rsm). methods: the studied flavanones were extracted from ...

Deoxynivalenol (DON) is a secondary metabolite of Fusarium culmorum and Fusarium graminearum and is one of the most common mycotoxin contaminants of wheat, barley, maize, and cereal-based food products (Canady et al., 2001; Schothorst and van Egmond, 2004). Like other trichothecenes, DON induces a spectrum of effects in farm and laboratory animals including emesis (DON has the trivial name ‘‘vo...

Four experiments were conducted to investigate the effects of deoxynivalenol (DON) from naturally contaminated dried distillers grains with solubles (DDGS) and the efficacy of feed additives in nursery pig diets. In Exp. 1, 180 pigs (10.3 ± 0.2 kg BW) were fed 1 of 5 diets for 21 d. Diets were 1) Positive Control (PC; < 0.5 mg/kg DON), 2) Negative Control (NC; 4 mg/kg DON), 3) NC + 0.10% Biofix...

fusarium culmorum which is considered as the causal agent of fusarium head blight, can produce deoxynivalenol (don), nivalenol (niv) and their acetylated derivatives. this study has been assessed in order to detect the tri13 gene using primer pairs tri13donr/tri13f and tri13r/tri13nivf, to investigate the potential of f. culmorum isolates in the production of don and niv in west azarbayjan prov...

To identify the specific biomarkers of exposure DON in chickens, a toxicokinetic study was performed via oral or intravenous application deoxynivalenol (DON). Doses 0.75 and 2.25 mg DON/kg body weight (BW) were administrated intravenously orally to chickens. Next, blood samples collected at several time points plasma obtained. Liquid chromatography–tandem mass-spectrometry (LC–MS/MS) used quant...

In this paper we describe ItLv (Interactive Timeline Viewer), a visualization tool currently used to depict the variants obtained in a textual collation. A textual collation is a process in which a base text is compared against several comparison texts to identify differences (variants) among them. The interactive options of ItLv provide different abstractions of a dataset by enabling the prese...

us believe) in any dialect in Scotland; in fact the tendency in all Scotch dialects is to pronounce it "jest." And as regards the alleged difference of opinion between Mr. Syme and Sir Henry Thompson, I heard Mr. Syme describe his interview with Dickens on the day it took place, and remember that he not only took a serious view of the condition of Dickens' foot, but also spoke of Sir Henry Thom...

For convenience, let us rewrite v(x,y) as a function of three parameters v(dc,don, p): the compressed discontinuity dc, the oriented normalized discontinuity don, and the relative coordinates of the screen-space pixel in the projected light space p. For the parameters dc and p, the description given in the Section 3.1 of the paper is sufficient for this supplementary document. However, we need ...

Abstract The primary objective of this study was to establish a current situation assessment of the possible occurrence of deoxynivalenol in cocoa and cocoa products. Since there was no analytic method for determining DON in cocoa and cocoa products, a special method was developed. The applicability and consistency of the method was confirmed by performing recovery assays on various cocoa produ...

Two of the most common species of toxin-producing Fusarium contaminating small cereal grains are Fusarium graminearum and F. poae; with both elaborating diverse toxins, especially deoxynivalenol (DON) and nivalenol (NIV), respectively. The objective of our work during the 2012-2014 growing seasons was to screen crops for the most commonly isolated Fusarium species and to quantify DON and NIV to...
