Various lignocellulose derived toxins, including furan derivatives (furfural and 5-hydromethylfurfural (HMF)), organic acids (acetic acid, formic acid, and ferulic acid) and lignin derivatives (vanillin, 4-hydroxybenzaldehyde, guaiacol, and phenol), are generated during pretreatment processing [ 3, 4].
This research focused on two classes of synthetic and naturally derived toxins with the specific goal of identifying materials that elicit rapid neurological impacts.
First, we showed that the presence of large and hydrophobic residues varying in availability in the primary sequences correspondingly affects the amount of these residues being used in the SSEs in accordance with linear behavioral patterns from empirical assessments of experimentally derived toxins and non-toxins.
In the case of X. bovienii bacterial strains, bacterially derived toxins could play a defensive role in protecting the insect cadaver from predators and competitors or could aid in killing the insect host.
Examples of environmentally relevant toxicants include industrial chemicals or manufacturing byproducts, metals, pesticides, herbicides, air pollutants, and other inhaled toxicants, particulates or fibers, and fungal, bacterial, or biologically derived toxins.
Further studies are needed to determine whether systemic endothelial activation observed in malaria is causally related to cytoadherence or invoked by circulating factors such as microparticles and other IE derived toxins.
Examples of environmental agents relevant to the NIEHS mission include industrial chemicals or manufacturing byproducts, metals, pesticides, herbicides, air pollutants and other inhaled toxicants, particulates or fibers, fungal, bacterial or biologically derived toxins.
Expression profiling of these genes in banana cells treated with known Foc derived toxins (FA and BEA) or the active culture/autoclaved filtrate (aFoc/fFoc) indicated differential regulation of the three genes in response to these four treatments.
These training grants aim to support research not only on chemicals known to be environmental pollutants but also on "fungal or bacterially derived toxins due to ambient exposures" as well as those infectious and parasitic agents that are "disease co-factors with an environmental toxicant exposure" (NIEHS 2006).
Reduced production of toxic secondary metabolites, for example, may provide an advantage against specialists that co-opt diet-derived toxins for their own defense [ 95, 96].
