21. Altitude training can produce slow recovery due to the stress of hypoxia . 22. Other possible effects include accelerated DNA repair, induction of cellular hypoxia , 23. Objective measurements of the severity of cerebral hypoxia depend on the cause. 24. Hypoxia and hypoglycemia trigger bioenergetic failure; mitochondria stop producing ATP energy.25. Hyperglycemia and hypoxia are also known to increase OPN expression. 26. Andreatta suffered from cerebral hypoxia for twenty minutes, reporting permanent damage. 27. A closely related disease to brain ischemia is brain hypoxia . 28. A decrease in synaptic transmission is also seen with hypoxia . 29. Such a death would be slower than the hypoxia death. 30. This inability introduces a diathesis to hypoxia in stagnant water.
