PAHs generally occur as complex mixtures (for example, as part of combustion products such as soot), not as single compounds.
In summary, when tested as single compounds, fungal VOCs affected A. thaliana in positive, negative or neutral ways.
We further investigated the effects of BRO, thyme extract as well as single compounds of thyme extract on enzymatic activity of 5-lipoxygenase (5-LO).
Consumers should also be informed that the vast majority of natural cosmetic products contain allergenic fragrance compounds, either as single compounds added or as natural constituents of various natural substances.
Our studies are well-based in our knowledge of their performance as single compounds.
Three phenols, BPA, benzophenone-3, and triclosan, were each above the LOD in at least 75% of study participants and were evaluated as single compounds in our analysis.
To study the effect of the size on transfection, the transfection efficacies of dimeric dendrimers (prepared and purified as single compounds) were compared to their monomers.
We examined various halogenated hydrocarbons for their capacity to inhibit gap junctional intercellular communication (GJIC) in normal human breast epithelial cells (HBEC) when given as single compounds or as mixtures.
With syntopic interaction, however, responses to mixtures follow sigmoidal dose response curves just as single compounds, so that the brain can use the same algorithms for concentration invariance for all odors, be they pure substances or mixtures.
Humans and wildlife do not usually experience XEs as single compounds, and in fact, they probably are exposed to dozens of them simultaneously, if low concentration ranges are considered [ 1, 2].
