Moreover, both rams and woodpeckers are scrupulous in the precise, single-direction fashion in which they smash their heads into things, whether trees or one another: The aim is such that there's very little side-to-side torsion exerted on the brain, none of the movement that induces whiplash injury and other kinds of damage.
There were many equally evil 20th-century regimes – Stalin, Mao, Idi Amin, Pol Pot – but none of these exert quite the same cultural and psychological charge as Nazism.
Considering this, it was surprising to find that the PCB mixture could exert a TH agonist effect in GH3 cells, but that none of the PCB congeners could exert such an action when tested alone.
None of the participants exerted this right.
Similarly, the inclusion of terms for exposure to other occupational agents, one by one and all together, suggested that none of these agents exerted a confounding effect on the association between lung cancer risk and occupational exposures to bitumen fumes [see Supplemental Material, Table S4 (doi:10.1289/ehp.0901800)].
The preliminary chemical analysis showed that for LD a number of fractions were found to exert a significant growth inhibitory effect at the 5% level (p = 0.05), however none of the fractions tested exerted a significant effect at the 1% level (p = 0.01) which may suggest that LD contains a number of moderately cytotoxic compounds that interact to elicit a significant cytotoxic effect in vitro.
Also, none of the tested compound exerts any activity against the pathogenic yeast species ( C. albicans) under these screening conditions.
Unfortunately, none of these therapeutic maneuvers exerted beneficial effects against oxygen free radical injury.
Of great interest is the conclusion that none of the assayed sweeteners exerted negative consequences on the viability either on the starter or on the probiotics [ 51].
However, none of the environmental factors exerted a strong effect on sex within their natural range, and some of them seemed to be largely dependent on the fish genotype.
