Reactive scope predicts that all animals have an adaptive ability to respond to stressors in their environment, termed reactive homeostasis, and that only when an animal's response to stressful stimuli exceeds a certain threshold (homeostatic overload) will stress have pathological effects.
Navigation in a dynamic environment requires reactive actions to avoid collision and navigate safely.
Real-time supply chain management in a rapidly changing environment requires reactive and dynamic collaboration among participating entities.
Shifts in binding energy observed for both Pd and S spectra of the used catalysts were examined in order to probe the change of electronic environment of reactive palladium center and the thiol ligand during the reaction.
According to concept of study, while industry tries to maintain the sustainability of production with the strategies of fossil fuel, renewable energies, energy recovery and nuclear energy usage, environment exhibits reactive approach to ensure its sustainability.
Since red blood cells are devoid of NOS, the assessment of red blood cells nitration can thus be considered as a simple index of the production in the cellular environment of reactive nitrogen species with a long range of action.
DNA damage occurs following a variety of stimuli including ionizing radiation (IR), ultraviolet radiation (UV), replication stress, chemicals from the environment, and reactive oxygen species that are produced as a byproduct of cellular metabolism.
These six elements are linked to some of the main changes observed during growth arrest and dormancy, such as the changes in the cell wall, the arrest in protein synthesis and the adaptation to a hypoxic environment with reactive nitrogen species [ 79, 80].
It stands to reason, therefore, that genes in the NmlR regulon may be important in adaptation to anaerobic conditions or in certain environments where reactive oxygen or nitrogen species are present, but they are possibly not as important once the anaerobic respiratory chain becomes highly induced.
In cancer environment, tumor-reactive T cells have also shown an upregulation of inhibitory molecules, such as programmed cell death-1 (PD-1) and cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4), which resemble T-cell exhaustion in chronic viral infection.
