Oxygen Sensation: Into Thick Air
Two recent studies show that a neural globin tunes oxygen responses in the nematode Caenorhabditis elegans. Analysis of wild C. elegans strains suggests that the commonly used Bristol strain may have adapted to life in the laboratory.
متن کاملHyperbaric oxygen improves nasal air flow.
OBJECTIVE We investigated whether hyperbaric oxygen (HBO2) treatment is able to cause any changes in the nasal peak inspiratory flow (NPIF) values of patients submitted to this therapy. STUDY DESIGN NPIF was measured in a group of 13 patients who were submitted to at least 10 sessions of 75 minutes long HBO2 treatments over a period of 20 days. HBO2 was prescribed to the patients to treat hea...
متن کاملAir or 100% oxygen in neonatal resuscitation?
For more than 100 years, three principles have guided the treatment of neonatal asphyxia: maintain body heat, free air passages of obstructions, and stimulate respiration by supplying air to the lungs for oxygenation of the blood. This article addresses the question of which gas, air or 100% oxygen, is best supplied to the lungs to stimulate respiration. Evidence-based studies are presented and...
متن کاملEffect of combined recompression and air, oxygen, or heliox breathing on air bubbles in rat tissues.
The fate of bubbles formed in tissues during the ascent from a real or simulated air dive and subjected to therapeutic recompression has only been indirectly inferred from theoretical modeling and clinical observations. We visually followed the resolution of micro air bubbles injected into adipose tissue, spinal white matter, muscle, and tendon of anesthetized rats recompressed to and held at 2...
متن کاملTumor-dependent kinetics of partial pressure of oxygen fluctuations during air and oxygen breathing.
The primary purpose of this study was to examine the kinetics of partial pressure of oxygen (pO2) fluctuations in fibrosarcoma (FSA) and 9L tumors under air and O2 breathing conditions. The overall hypothesis was that key factors relating to oxygen tension fluctuations would vary between the two tumor types and as a function of the oxygen content of the breathing gas. To assist in the interpret...
