Formation of acrylamide in potato products and its dietary exposure
… moreover contribute significantly to the dietary acrylamide exposure. Therefore, this study focuses on these foodstuffs. The Maillard reaction plays a key role in the formation of acrylamide. This reaction also contributes to the pleasant sensory characteristics of deep-fried potatoes, …

Growth Rate and Performance Effects on Watersnakes (Nerodia Sipedon) from Dietary Exposure to Heavy Metals
Compared to other taxa, very little is known about reptile toxicology and the fitness effects that contaminants may cause. This study examines trace element concentrations, growth rates and performance measures in Northern Watersnakes, Nerodia sipedon when fed fish from a polluted mining-waste site …

Methodological focus and application of exploratory dietary patterns in epidemiological research
… to adequately measure and account for complete dietary exposure. The exploratory approach to dietary patterns is a useful method that utilizes multivariate data reduction techniques to summarize overall dietary exposure into variables that can represent diet in observational studies. This …

Comparative analyses of aryl hydrocarbon receptor structure, function, and evolution in marine mammals
… compounds (DLC). Chronic environmental or dietary exposure to these chemicals can disrupt the function of reproductive and immune systems, as well as cause developmental defects in laboratory animals. The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor, mediating …

Interactions Among Steroid and Xenobiotic Response Cascades in the Regulation of CYP6B1
… enhanced in vitro transcription of CYP6B1v3. Dietary exposure of black swallowtail caterpillars to either allelochemical alone induced P450-mediated xanthotoxin metabolism in vivo; however, simulataneous exposure to both chemicals repressed in vivo P450-mediated metabolism, possibly due to …

Transcriptional response and DNA adduct analysis of murine liver exposed to aflatoxin B₁ by Jeanette Louise Allen Fiala.
Human dietary exposure to aflatoxin B1 (AFB1) is linked to hepatocellular carcinoma (HCC), especially in areas where significant hepatitis B infection is concurrent. Susceptibility to this carcinogen varies among species. Neonatal mice, like rats and most other species, are highly sensitive to the …

Xenobiotic detoxification in the navel orangeworm Amyelois transitella (Lepidoptera: Pyralidae)
… transcribed in the navel orangeworm midgut. Dietary exposure to two phytochemicals found in almonds and pistachios, chlorogenic acid and quercetin, increases survival of navel orangeworms exposed to α-cypermethrin. These phytochemicals may decrease toxicity of the pesticide by inducing the …

Spread of Red Imported Fire Ant, Solenopsis invicta, in Virginia and effects of sub-lethal exposure to agrochemicals on its behavior
… the behavior of S. invicta through neonicotinoid exposure. We found detectable levels of neonicotinoids in the soil of the ant mounds as well as in the ants themselves. In addition, we investigated the effects of dietary exposure to imidacloprid on foraging behavior in a laboratory setting. We …

The Complex Interactions between Genetics and Environment: Diet, Inflammation and Intestinal Tumorigenesis
… olive oils, we demonstrate that high amounts of dietary fats can have differential effects on DIO and MetS, as well as on intestinal tumorigenesis when compared to ApcMin/+ fed corresponding calorically equivalent control diets that contained 10% fat from these same sources. Diets constructed …

Improving the dietary management of orofacial granulomatosis
… free diet avoids the highest sources, some dietary exposure remains. Atopy rates are high in patients with OFG and a recent study identified a high rate of pollen sensitisation to pollens associated with oral allergy syndrome (OAS). OAS is an allergic disorder manifesting immediate lip …

Aspects of ecosystem health in the Colorado River Delta, Mexico
… where reproductive impairment in birds from dietary exposure is reported. Concentrations of DDE exceeded the lower critical dietary level for sensitive species in 30% of biota samples. No clear relationship could be found between the concentration of Se in bottom material and the …

Modelling the fate and bioaccumulation potential of organic chemicals in China
… their fate in the environment and corresponding exposure to organisms (including humans) has only been measured for a limited number of substances. Modelling tools have been demonstrated to be an economical alternative to measurement data for the assessment of chemical fate and exposure. …

Assessment of dietary background exposure of the Irish adult population to dioxins and PCBs particularly taking into account additional exposure due to the 2008 Irish dioxin food contamination incident
… Irish Adult Food Consumption Data, to estimate dietary background exposure of Irish adults to dioxins and PCBs. Furthermore, all available information on the 2008 Irish pork dioxin food contamination incident was collated and analysed with a view to evaluate any potential impact the incident may …
