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 کاملInfluence of oxygen-enrichment air intake and bioethanol–gasoline blends on exhaust emissions and fuel consumption of gasoline engine
Among human activities, motor vehicles play the most important role in air pollution. Air pollution has negative impacts on people and on the environment. In this paper the effect of oxygen-enriched air (20.8%, 21.8%, 22.8%, 23.8% and 24.8%) and different bioethanol-gasoline blends (zero, 5%, 10%, 15%, 20% and 25%) in different engine speeds (1000 rpm, 2000 rpm and 3000 rpm) on the amount o...
متن کاملAir-activated chemical warming devices: effects of oxygen and pressure.
Air-activated chemical warming devices use an exothermic chemical reaction of rapidly oxidizing iron to generate heat for therapeutic purposes. Placing these products in a hyperbaric oxygen environment greatly increases the supply of oxidant and thus increases the rate of reaction and maximum temperature. Testing for auto-ignition and maximum temperatures attained by ThermaCare Heat Wraps, Play...
