• Anoxic
  • In contrast, anoxia per se results in limited changes to cardiac AP shape or ion current densities in turtle and crucian carp, suggesting that anoxic modifications of cardiac electrophysiology to reduce ATP demand are not extensive. (biomedsearch.com)
  • Routine cardiac workload mimicked in vivo conditions at the given temperatures, and the effects of anoxia were evaluated as maximal cardiac performance before and after 20 min of anoxic perfusion. (biologists.org)
  • For this purpose, Arabidopsis cell suspension cultures grown in a stirred bioreactor were subjected to a severe anoxic stress and analyzed during anoxia and re-oxygenation for alteration in ROS and NO as well as in antioxidant enzymes and metabolites. (frontiersin.org)
  • Control measures for T. bisselliella (and similar species) include the following: Anoxic measures work by displacing oxygen with an inert gas, asphyxiating the insects Carbon dioxide anoxia - Similar to cryofumigation, but using compressed dry carbon dioxide gas to exclude oxygen Treatment for one week at 25 °C (77 °F) is recommended. (wikipedia.org)
  • This property leads to daily anoxic cycles on small geographic scales and seasonal cycles of anoxia on the larger scale. (wikipedia.org)
  • contrast
  • By contrast, cardiac function failed sooner during anoxia as temperature was increased and maximal performance after reoxygenation was reduced by 25%, 35% and 55% at 10°C, 15°C and 18°C, respectively. (biologists.org)
  • In contrast, in anoxia, fewer diatoms were initially ingested and these were not assimilated or metabolized further, but remained visible within the foraminiferal cytoplasm even after 4 weeks. (epfl.ch)
  • survival
  • By examining if fundamental cellular mechanisms have been conserved during the evolution of anoxia tolerance we hope to have provided a framework for the design of future experiments investigating cardiac cellular mechanisms of anoxia survival. (biomedsearch.com)
  • Overall, the evaluation of cell defenses during anoxia and re-oxygenation in Arabidopsis cell cultures revealed that the immediate response involving the overproduction of reactive species activated the antioxidant machinery including ascorbate-glutathione system, α-tocopherol and the ROS-scavenging enzymes ascorbate peroxidase, catalase, and peroxidase making cells able to counteract the stress toward cell survival.

  • tolerance
  • The pronounced anoxia tolerance of turtles and carp is linked to a marked depression of metabolic rate, which is further enhanced at low temperatures, so that anaerobic metabolism can balance energy consumption and reduce the rate of waste production (Jackson, 2000 , 2002 ). (biologists.org)
  • metabolism
  • Together, our results show that anoxia induced a greatly reduced rate of heterotrophic metabolism in Ammonia tepida on a time scale of less than 24 hours, these observations are consistent with a state of dormancy. (epfl.ch)
  • Temperature
  • It was concluded that 1) N2-delivery patterns consisting of long anoxia, short normoxia and high cycle frequency increased disruption of brain [K+]o baseline maintenance, 2) males were more susceptible to repeated anoxia than females at room temperature, and 3) hypothermia had a protective effect on brain K+ homeostasis during repetitive anoxia.

  • mechanism
  • Ash and dissolved trace metals from Sevier and Caribbean eruptions provided nutrients to the water column, which was the driving mechanism for anoxia in the Western Interior Seaway. (wikipedia.org)
  • hearts
  • Hearts from the reserpine-treated rats had higher left ventricular pressures, maximal rate of left ventricular pressure rise, and lactate output after 2 minutes of anoxia than the hearts from control rats. (ahajournals.org)
  • levels
  • Anoxia also induced a slight but significant increase of α-tocopherol levels measured at the end of the treatment. (frontiersin.org)
  • Similar
  • This is unfortunate, because anoxia can be easily confused for other problems which share similar symptoms such as a pulmonary embolism, polycythemia vera, or pulmonary hypertension. (medicalmalpracticehelp.com)
  • Loss
  • Repetitive anoxia resulted in a loss of the ability to maintain [K+]o baseline at ~10 mM. (queensu.ca)
