However, at certain concentration of hydroxyl groups the adsorption of Pt cluster is stabilized, because at these electron densities hybridization between Pt 5d and C 2p orbitals are relatively more favored.
At certain concentrations, spherical nanoparticles of PPy formed and the thermal properties of the material were significantly enhanced.
This argues that only certain ligands at certain concentrations are capable of inducing trained immunity.
Additionally, C6- and C8-HSL treatments stimulated K+ uptake in root cells only at certain concentrations, whereas all tested concentrations of C12-HSL induced K+ uptake.
The combination of both drugs at certain concentrations showed a complete protection of the cells, a significant decrease in intracellular peroxide production (dichloro-fluorescein diacetate (DCF-DA) fluorescence, 4-h incubation), in lipoperoxidation (thiobarbituric acid reactive substances fluorescence, PPF 6.25 μM+TX 12.5 μM) and an additive protective effect.
At certain concentrations or doses, > 75% of the chemicals they identified are known to negatively impact the skin, eyes, and other sensory organs; the respiratory system; the gastrointestinal system; and the liver.
These results, considered with the strong effect of fDE (gases alone), point to the complexity of studying the short-term cardiac effects of multipollutant mixtures and the interaction of their components at certain concentrations.
In our Ca2+ imaging study, SCCs isolated from VNOs responded to a variety of chemicals at certain concentrations, including urine samples, pheromone, odorants, bitter-tasting substances and trigeminal irritants.
At certain concentrations, NaNO2 promotes not only the peroxidation of lipids [57] but also the conversion of oxyhemoglobin (Fe2+) to methemoglobin (Fe3+) [59], [59], which spontaneously converts to hemichromes at a rate that depends on its own tertiary structure [60].
