A total of 122 wheat varieties obtained from the Nordic Genetic Resource Center were infected artificially with an aggressive Fusariumasiaticum strain in a field experiment. We calculated the severity of Fusarium head blight (FHB) and determined the deoxynivalenol (DON) content of wheat grain, straw and glumes. We found DON contamination levels to be highest in the glumes, intermediate in the s...

In 1999, the Department of the Navy (DoN) began a suicide surveillance program using the DoN Suicide Incident Report (DONSIR) to collect data on completed suicides in the Navy and Marine Corps. The DONSIR significantly advances the capability of DoN to track and analyze data on completed suicides over time. The long-term goal of this program is to improve suicide prevention by identifying and m...

We investigated a proposed synergistic effect of deoxynivalenol (DON) and lipopolysaccharides (LPS) on small intestinal architecture and epithelial barrier integrity in pigs. Crypt depth and intestinal cell proliferation were analyzed, as well as expression of zonula occludens protein-1 (ZO-1) and β-catenin of the apical junction complex along the small intestine. Barrows (26.2±4.1 kg) were fed...

This paper uses a cases study about a technical decision to review to computerethics decision procedures. 1. Decision making for the ethical Even before Jim Moor’s seminal paper on Core Values, Kidder [2002] declares “... that despite differences in religion, philosophy, geographical location, nationality, and race, human beings have a common belief in five core values: honesty, responsibility,...

Deoxynivalenol (DON) is a type B trichothecene mycotoxin that is commonly detected in cereals and grains world-wide. The low-tolerated levels of this mycotoxin, especially in mono-gastric animals, reflect its bio-potency. The toxicity of DON is conventionally attributed to its ability to inhibit ribosomal protein biosynthesis, but recent advances in molecular tools have elucidated novel mechani...

The trichothecene mycotoxin deoxynivalenol (DON), commonly present in contaminated grains worldwide, induces expression of the chemokine interleukin (IL)-8 in human monocytes. The purpose of this study was to test the hypothesis that DON modulates transcriptional and posttranscriptional regulation of IL-8 expression in the U937 human monocyte model. When U937 cells were transfected with a wild-...

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 fr...

Fusarium head blight (FHB), mainly caused by Fusarium graminearum, is a devastating disease of wheat that results in economic losses worldwide. During infection, F. graminearum produces trichothecene mycotoxins, including deoxynivalenol (DON), that increase fungal virulence and reduce grain quality. Transgenic wheat expressing a barley UDP-glucosyltransferase (HvUGT13248) were developed and eva...

Deoxynivalenol (DON) is a potent mycotoxin and virulence factor produced by Fusarium graminearum. We examined the expression of the core DON biosynthetic gene Tri5 during wheat head infection of susceptible and resistant cultivars and susceptible cultivars treated with strobilurin fungicides (e.g., azoxystrobin). DON was quantified to correlate expression with toxin accumulation. The highest Tr...
