Through mechanisms

In addition to failure as a result of their utihty supply, items of equipment are subject to individual failure through mechanical malfunction. Such items include pumps, fans, compressors, mixers, instruments and control valves. The process upset resulting from such malfunctions (e.g., loss of a reflux pump) may in turn result in emergency conditions and the potential for overpressure. These contingencies should be examined and evaluated.

Large molecules can enter or leave cells through mechanisms such as endocytosis or exocytosis. These processes often require binding of the molecule to a receptor, which affords specificity to the process.

Nonimmune stresses can increase circulating proinflammatory cytokine concentrations. Hemorrhage, and certain psychological and physical stresses all increase HPA activity through mechanisms that may include catecholamines and peripheral CRH [reviewed in 29], However, in some experiments correlations between plasma ACTH and IL-6 levels in models of immune and nonimmune stresses are low. The role played by cytokines in the ACTH response to nonimmune stresses has not been established.
