Ischemia induces metabolic stress that is secondary to oxygen, amino acids and glucose deprivation and activates complex evolutionarily conserved responses, including the UPR.
After formation of ·O2- in arsenic-induced oxidative stress, a cascade of secondary reactive oxygen species (ROS), such as hydrogen peroxide (H2O2) and hydroxyl radical (·OH) is generated [ 70].
When aspiration does occur, the volume of fluid entering the lungs rarely exceeds a glassful; the lungs "fill with water" chiefly because of an abnormal accumulation of body fluids (pulmonary edema) that is a secondary complication of oxygen deprivation.
Benzamides can be obtained in good to high yields by reaction of benzoin, primary or secondary amines, molecular oxygen and electrogenerated superoxide anion (obtained with galvanostatic method).
Three parts defined as transpassive dissolution, secondary passivity and oxygen evolution can be observed in the transpassive potential region of the anodic polarization curves.
Drainage of these wetlands for agriculture beginning in the late 1800s exposed the secondary pyrite to oxygen and initiated a second cycle of acid sulfate weathering that led to some of the reports of "unproductive black soils".
See related research by van Beest et al., Many physicians believe that global hypoxia secondary to inadequate oxygen delivery (DO2) is responsible for organ failure during severe sepsis.
Fainting is the result of compromised cerebral function secondary to decreased oxygen or glucose availability, which can be caused by various mechanisms, of which collapsed immobility is just one.
Meanwhile, the elevation of Epo expression by nitrate in the kidneys, which was exacerbated by environmental hypoxia, is consistent with the notion of enhanced renal hypoxia secondary to diminished oxygen delivery as a result of relative anemia.
Perhaps the most striking difference however was in caspase-3, a marker of cellular apoptosis, the level of which fell dramatically in the protocol group and remained at a much lower level throughout the 72 hours, suggesting that EGDT reduced the secondary insult of oxygen debt.
