• Hypoventilation is not synonymous with respiratory arrest, in which breathing ceases entirely and death occurs within minutes due to hypoxia and leads rapidly into complete anoxia, although both are medical emergencies.
• Reperfusion injury, sometimes called ischemia-reperfusion injury (IRI) or reoxygenation injury, is the tissue damage caused when blood supply returns to tissue (re- + perfusion) after a period of ischemia or lack of oxygen (anoxia or hypoxia).
• Rhodocyclus (type genus) species can grow photoheterotrophically or photoautotrophically (using molecular hydrogen as their electron donor) under anoxia or heterotrophically on fatty acids under air.
• Severe cerebral hypoxia and anoxia is usually caused by traumatic events such as choking, drowning, strangulation, smoke inhalation, drug overdoses, crushing of the trachea, status asthmaticus, and shock.
• Research questions investigated by students during courses and their thesis work at the Laboratory included: What are the effects of the natural light gradient on predator-prey interactions? How can the predator best see the prey without being seen? How does the focussing of small waves oscillating light regime influence camouflage and attack strategy? What are the influences of the different frequencies of microturbulences? How do such effects change at the moment when herring larvae join into schools? What role does the phenomenon of aggregation play? Do ocean physics create or alter organism-aggregations? Can the dynamics of aggregations effect ocean physics at the microscales? Are there effects of the surface waves? What are the distribution and dynamics of microbubbles caused by turbulences and gas-oversaturations? How can the organisms orient in respect to micro-gradients of the ocean physics? How do they survive in the direct vicinity of undulating anoxia and hypoxia? Why are eelpouts, sticklebacks and herrings so extremely successful in the Baltic while cod is not? What are the effects and functions of schooling for feeding and microscale-orientation? What is the behavior of fish in netcages and how much food is lost from the cages.
• Early Jurassic anoxia triggered the evolution of the oldest holoplanktonic gastropod Coelodiscus minutus by means of heterochrony.
• Hypolimnetic anoxia can also contribute to buildups of iron, manganese, and sulfide in the profundal zone.
• The carbon monoxide combines with haemoglobin in the bloodstream to form carboxyhemoglobin, which prevents the blood cells carrying oxygen, and can therefore result in suffocation by lack of oxygen known as anoxia.
• 5 mg/L, though, it is capable of surviving in extreme hypoxia, because it is an oxygen conformer, becoming much less active in hypoxic water, and even surviving virtual anoxia for up to two hours.
• GDF11 contributes to limiting functional damage of mitochondria in cardiomyocytes (heart cells) following ischemic (lack of blood flow) injury or anoxia (oxygen deprivation) insult, and repressing apoptosis in mitochondria-dependent and mitochondria-independent manners by increasing telomerase activities.
• Nizofenone (Ekonal, Midafenone) is a neuroprotective drug which protects neurons from death following cerebral anoxia (interruption of oxygen supply to the brain).
• A similarly broad definition of HABs was adopted by the US Environmental Protection Agency in 2008 who stated that HABs include "potentially toxic (auxotrophic, heterotrophic) species and high-biomass producers that can cause hypoxia and anoxia and indiscriminate mortalities of marine life after reaching dense concentrations, whether or not toxins are produced".
• Zahn infarcts are unique in that there is collateral congestion of liver sinusoids that do not include areas of anoxia seen in most infarcts.
• Peatlands arise because of incomplete decomposition of organic matter, usually litter from vegetation, due to water-logging and subsequent anoxia.
• Crucian carp also counteracts the damaging effects of anoxia by swimming into cooler water, a phenomenon known as voluntary hypothermia.
• During deep hypoxia and anoxia ATF- and ADF- hydrolyzing ferments disappear from the surface of endothelial cells, which leads to enhanced aggregation of platelets and endothelium hormone secretion.
• Poulton and his collaborators did research on oesophageal pain, dissociation curves of blood, physiological effects of anoxia, and creatinine excretions in dietary modifications.
• Blackmore in her chapter 'Near-death experiences' in The Skeptic Encyclopedia of Pseudoscience discusses various alternative explanations for these experiences, including expectation, administered drugs, endorphins, anoxia (oxygen depletion) or hypercarbia (excess carbon dioxide) and temporal lobe stimulation.
• However, the persistence of anoxia and euxinia over the late Tonian despite some increases in oxygen content meant eukaryotic diversity overall remained low.
• An alternate model for the development of anoxia is that epicontinental seaways became salinity stratified with strong haloclines, chemoclines, and thermoclines.
