Sporadic, direct observations over a 50 yr period inadequately characterize the history of seasonal hypoxia and anoxia in Chesapeake Bay, alarge estuary threatened by eutrophication. (usgs.gov)
Hypoxia and anoxia as a result of eutrophication continue to threaten lucrative commercial and recreational fisheries worldwide. (nature.com)
Water-column anoxia2
This implies a temporal coupling between water-column anoxia and Mo fixation even though fixation occurs only within sediments. (usgs.gov)
Trace and major element, iron speciation, and biomarker data indicate that water column anoxia was established during episodes when inputs of land-derived higher plant organic carbon and highly weathered detrital clays and silts became relatively higher. (open.ac.uk)
Oceanic anoxia6
Periods of oceanic anoxia have had a major influence on the evolutionary history of Earth and are often contemporaneous with mass extinction events. (elsevierpure.com)
The EH is characterized by shifts toward lower δ 238 U values (from -0.37‰ to -0.65‰), indicative of an expansion of oceanic anoxia, and higher Th/U ratios (from 0.06 to 0.42), indicative of drawdown of U concentrations in seawater. (elsevierpure.com)
Using a mass balance model, we estimate that this isotopic shift represents a sixfold increase in the flux of U to anoxic facies, implying a corresponding increase in the extent of oceanic anoxia. (elsevierpure.com)
The intensification of oceanic anoxia coincided with, or slightly preceded, the EH and persisted for an interval of at least 40,000 to 50,000 y following the EH. (elsevierpure.com)
Oceanic anoxia has been proposed as a proximate cause of the end- Permian mass extinction (EPME), but evaluation of this hypothesis is hampered by limited detailed knowledge of its timing and extent. (elsevierpure.com)
Three earlier δ 238 U studies of Tethyan sections inferred development of extensive oceanic anoxia at the EPME. (elsevierpure.com)
Vitro1
Moclobemide attenuates anoxia and glutamate-induced neuronal damage in vitro independently of interaction with glutamate receptor subtypes. (neuronexperts.com)
Cerebral1
In a brain slice model of cerebral anoxia, 1 minimum alveolar concentration isoflurane decreases glutamate release to a similar extent that hypothermia (28 degrees C) does. (silverchair.com)

This installation is composed by the video "Glass Memory" and blown glass sculptures , nesting three different smells: Anoxia, Barricada and Lacrimae - presented as in reference to the criminal fires in Amazon Forest that happened in 2019. (joselycarvalho.com)
Anoxic4
Anoxic anoxia happens when there's not enough oxygen available to your body. (healthline.com)
One form of anoxic anoxia can happen when you're at high altitudes. (healthline.com)
Exerting yourself when you're at high altitudes can make the effects of anoxic anoxia worse. (healthline.com)
Anoxic anoxia can also be caused by anything that keeps your lungs from working properly and limiting the body's oxygen. (healthline.com)
Don't wait until symptoms start to point to anoxia. (healthline.com)
The symptoms of anoxia may not always be obvious at first. (healthline.com)
Conservation2
This book describes successful insect eradication procedures developed at the Getty Conservation Institute and elsewhere, whereby objects are held in an atmosphere of either nitrogen or argon containing less than 1000 ppm of oxygen-a process known as anoxia-or in an atmosphere of more than 60 percent carbon dioxide. (getty.edu)
Shin Maekawa is senior scientist in the Scientific Program at the Getty Conservation Institute, where he coordinates nitrogenanoxia projects. (getty.edu)
Insects1
Anoxia eliminates the investing insects at any stage of their development - eggs, larva or adults. (expmstore.com)

Glutamate released from rat cortical brain slices during chemical anoxia (100 microM NaCN) was measured continuously with a fluorescence assay. (silverchair.com)
Chemicals1
Toxic anoxia occurs when you take in toxins or other chemicals. (healthline.com)
Internal1
Each type of anoxia has a different internal or external cause. (healthline.com)
Treatment2
An anoxia treatment is where an item (or in this case, many items) that has been infested with pests, fungi, or bacteria can be placed in a closed environment and the oxygen reduced to less than 0.1% for four to six weeks, or even longer, using nitrogen or CO₂. (cardiff.ac.uk)
Results from tourniquet anoxia and hyperbaric oxygen techniques combined with megavoltage treatment of sarcomas of bone and soft tissues. (extivita.org)
Occurs1
Anemic anoxia occurs when your blood can't carry enough oxygen around your body to keep your organs functioning properly. (healthline.com)
Tissue1
Dextrose-, adenosine- and magnesium-induced protective actions during anoxia and reperfusion in canine Purkinje tissue. (meharryresearch.org)
Death1
Death from anoxia in an abandoned cesspool. (psu.edu)
damage is usually a secondary result of anoxia caused by loss of lung function. (cdc.gov)
Conditions1
a measure of the severity of hypoxic conditions Oxygen toxicity (hyperoxia), the opposite condition of hypoxia, an excess of oxygen in body tissues Oxygen-free (disambiguation) This disambiguation page lists articles associated with the title Anoxia. (wikipedia.org)
Body1
When hypoxia turns into anoxia, the parts of your body that need oxygen to function can stop working properly. (healthline.com)
Major1
Here, we show that photochemically produced CCRs are immobilized in highly viscous organic aerosol particles and act as a major sink for O 2 inside particles, thereby inducing anoxia. (nature.com)
Events1
Cardiovascular events are the most common cause of stagnant anoxia. (healthline.com)
Period1
These findings challenge previous hypotheses of an extended period of whole-ocean anoxia prior to the end-Permian extinction. (elsevierpure.com)
Work1
The aim of this work was to investigate the role of oxygen in the photobleaching of fluorophores bound to DNA in fixed cells, and to explore whether anoxia could minimize such bleaching. (ox.ac.uk)
