We observed that the antiaromatic p-system of the norcorroles easily forms close face-to-face stacking structures in order to diminish their antiaromatic nature. This phenomenon is not generally observed in aromatic compounds, for which close face-to-face p-stacking typically leads to large ...

ears, which were weighed to determine the inflammation. percentage of inhibition was determined by the formula expressed below: $$ inhibition\ \%=\left(\vardelta w\ control - \frac{\vardelta w\ treatment}{\vardelta w}\right)\times 100 $$ where Δw = w t − w nt ; ...
The exposure to Poly Aromatic Compounds enhances the level of oxidative stress and genotoxic damage, and thus contributes to skin aging process [17]. It was also observed that metals present in PM are largely responsible for the observed oxidative stress. Metals promote ROS production and cause ...
