Physiological and Genomic Consequences of Intermittent Hypoxia Invited Review: Physiological and pathophysiological responses to intermittent hypoxia

TLDR
Neubauer et al. as mentioned in this paper summarized the physiological adaptations to and pathophysiological consequences of intermittent hypoxia with special emphasis given to the pathophysiology associated with obstructive sleep apnea.
Abstract
Neubauer, Judith A. Invited Review: Physiological and pathophysiological responses to intermittent hypoxia. J Appl Physiol 90: 1593–1599, 2001.—This mini-review summarizes the physiological adaptations to and pathophysiological consequences of intermittent hypoxia with special emphasis given to the pathophysiology associated with obstructive sleep apnea. Intermittent hypoxia is an effective stimulus for evoking the respiratory, cardiovascular, and metabolic adaptations normally associated with continuous chronic hypoxia. These adaptations are thought by some to be beneficial in that they may provide protection against disease as well as improve exercise performance in athletes. The long-term consequences of chronic intermittent hypoxia may have detrimental effects, including hypertension, cerebral and coronary vascular problems, developmental and neurocognitive deficits, and neurodegeneration due to the cumulative effects of persistent bouts of hypoxia. Emphasis is placed on reviewing the available data on intermittent hypoxia, making extensions from applicable information from acute and chronic hypoxia studies, and pointing out major gaps in information linking the genomic and cellular responses to intermittent hypoxia with physiological or pathophysiological responses.

Ca2+/Calmodulin Kinase-dependent Activation of Hypoxia Inducible Factor 1 Transcriptional Activity in Cells Subjected to Intermittent Hypoxia

TL;DR: Observations suggest that IH induces HIF-1 transcriptional activity via a novel signaling pathway involving CaM kinase, and this effect was blocked by KN93.

Work at high altitude and oxidative stress: antioxidant nutrients.

TL;DR: The significant unanswered question concerning altitude exposure and antioxidant supplementation is when does oxidative stress become potentially damaging enough to merit antioxidant therapy and conversely, what degree of oxidative stress is necessary to foster the adaptive response of altitude exposure.

Oxygen-sensing neurons in the central nervous system

TL;DR: This mini-review summarizes the present knowledge regarding central oxygen-chemosensitive sites with special emphasis on their function in regulating changes in cardiovascular and respiratory responses and highlights real opportunities for future research.

Effects of hypoxia on the brain: neuroimaging and neuropsychological findings following carbon monoxide poisoning and obstructive sleep apnea.

TL;DR: It was found that hypoxia due to obstructive sleep apnea and CO poisoning resulted in neuropathological changes and neuropsychological impairments and the observed group differences provide insight into the relationship between etiology of injury, neuro Pathological changes, and clinical presentation.

The Occurrence of Sleep-Disordered Breathing among Middle-Aged Adults

TL;DR: The prevalence of undiagnosed sleep-disordered breathing is high among men and is much higher than previously suspected among women, and is associated with daytime hypersomnolence.

Nitric oxide, superoxide, and peroxynitrite: the good, the bad, and ugly.

TL;DR: The rapid diffusion of nitric oxide between cells allows it to locally integrate the responses of blood vessels to turbulence, modulate synaptic plasticity in neurons, and control the oscillatory behavior of neuronal networks.

Prospective study of the association between sleep-disordered breathing and hypertension.

TL;DR: A dose-response association between sleep-disordered breathing at base line and the presence of hypertension four years later was found that was independent of known confounding factors and suggest that sleep- disordered breathing is likely to be a risk factor for hypertension and consequent cardiovascular morbidity in the general population.
