  • enzymes
  • It is possible that the same activating enzyme activates these two oxygen-sensitive enzymes. (nii.ac.jp)
  • These findings sugggest that the variable oxygen concentration in dental plaque affects strongly the activities of these enzymes and then the microorganisms involved in the initiation and development of dental caries as well as periodontal diseases. (nii.ac.jp)
  • blood flow
  • During adenosine infusion, great cardiac vein blood flow and oxygen content were significantly increased and myocardial oxygen consumption and lactate extraction were significantly reduced from baseline without a significant increase in rate-pressure product in this subset of patients with syndrome X. CONCLUSIONS: Patients with syndrome X with abnormal exercise scintigrams have high susceptibility to myocardial ischemia during exercise or pharmacologic stress tests, probably owing to reduced coronary flow reserve.

  • therapy
  • Hyperbaric oxygen therapy (HBOT) involves the administration of inhaled 100% oxygen at increased ambient pressure inside a closed vessel. (bioportfolio.com)
  • Use of hyperbaric oxygen therapy in quinine-associated visual disturbances. (bioportfolio.com)
  • Hyperbaric oxygen (HBO2 ) therapy is infrequently reported as a treatment for poison-induced retinal damage. (bioportfolio.com)
  • The purpose of this experimental study was to investigate the effect of hyperbaric oxygen (HBO2) therapy combined with microfracture technique in the treatment of cartilage lesions. (bioportfolio.com)
  • Treatment for polycythemia vera includes administering oxygen, radioisotope therapy, or chemotherapy agents for bone marrow suppression. (rophemhealth.com)
  • Common uses of oxygen include production of steel , plastics and textiles , brazing, welding and cutting of steels and other metals , rocket propellant , oxygen therapy , and life support systems in aircraft , submarines , spaceflight and diving . (wikipedia.org)
  • chemical
  • Priestley, however, called oxygen "dephlogisticated air", and did not recognize it as a chemical element. (wikipedia.org)
  • The name oxygen was coined in 1777 by Antoine Lavoisier , who first recognized oxygen as a chemical element and correctly characterized the role it plays in combustion. (wikipedia.org)
  • form
  • Then, we found that the enzyme in S.mutans is also highly oxygen-sensitive and that this enzyme has a reversible inactive form. (nii.ac.jp)
  • The inactive form of this enzyme was activated by a similar way as found in another highly oxygen-sensitive enzyme, pyruvate formate-lyase. (nii.ac.jp)
  • life
  • The purpose of this study is to determine whether the hyperbaric oxygen treatment reduces pain and improve the life quality in trigeminal neuralgia patients. (bioportfolio.com)
  • The longest-lived radioisotope is 15 O with a half-life of 122.24 seconds , while the shortest-lived isotope is 12 O with a half-life of 580(30)×10 −24 seconds (the half-life of the unbound 11 O was not measured). (wikipedia.org)
  • Safe use of RTGs requires containment of the radioisotopes long after the productive life of the unit. (wikipedia.org)
  • In addition to that, the radioisotopes have either a too short (e.g., 20 minutes for 11 C) or too long (e.g., 57.4 days for 125 I) half-life, making them impractical for clinical use. (hindawi.com)
  • treatment
  • Each subject will receive a series of forty 2 hour treatments, delivered once a day, 5 days a week, within the hyperbaric oxygen chamber.There will be assessments completed before treatment series begins, 3 weeks and 6 weeks into treatment and then again at the end of treatment. (bioportfolio.com)
  • The primary purpose of this study is to assess whether hyperbaric oxygen treatment improves neurological function in patients who exhibit white matter hyperintensities on MRI examination. (bioportfolio.com)
  • How radioisotopes are used in the diagnosis and treatment of disease? (chechenprogrammers.ru)
