However, because of the highly reactive nature of these oxygen reactive species and their short half-lives, it had been difficult to investigate oxidative damage in vivo [ 24].
In addition, we concluded that the major reasons for the inactivation process of bacteria is because of the action of the reactive oxygen and nitrogen species which formed from ambient air, while the charged particles played a minor role in the inactivation process.
Because of the intrinsically reactive nature of aluminium metal, alumina layers are either already present on an aluminium surface or form within a matter of seconds on pre-etched aluminium.
Because of the highly reactive nature of potassium metal, it must be handled with great care, with full skin and eye protection and preferably an explosion-resistant barrier between the user and the metal.
Because of the highly reactive nature of ROS, it is difficult to directly demonstrate their presence in vivo.
5, 14, 15 The carcinogenicity may not reach the lower airway and lungs because of the highly reactive and rapid metabolite properties, suggesting that organs without direct contact with formaldehyde do not develop neoplasia.
Of these, intermediate monocytes are characterized as the most proinflammatory because of the active production of the reactive oxygen species and inflammatory cytokines such as tumor necrosis factor (TNF -α and inTNF -αkin (IL)-1β.
It is clear that the approximate analytical based model cannot be expected to predict the absorption rates under practical conditions because of the complicated nature of the reactive absorption processes.
