nitrox

12/01/2005 - "Compared to breathing nitrox, these data indicate that heliox improved the distribution of inspired gas, thereby recruiting more gas exchange units, improving gas exchange efficiency, reducing ventilatory and oxygen requirements, and attenuating lung inflammation. "

05/01/2016 - "In the present study, we cultured MDA-MB-231 cells in a hypoxic gas mixture to simulate the hypoxic environment in tissues and to determine how hypoxia conditions could affect the cell proliferation, apoptosis, cytotoxicity, and colony-forming ability. "
05/01/2003 - "In each trial they were immersed in 28 degrees C water for 90 min, and inspired either room air (air trial) or a hypoxic gas mixture (hypoxia trial; 11.5% O2/88.5% N2). "
01/01/2018 - "(2) CO2 adjunction to hypoxic gas mixture did not modify CO, despite a higher CaO2 in combined condition than in hypoxia. "
11/13/2013 - "Acute, mild hypoxia was induced by changing the oxygen saturation of inhaled air from 21% to 15% using a hypoxia generator with subjects breathing the hypoxic gas mixture for 10 minutes. "
01/01/2012 - "The influence of acute normobaric hypoxia on NO metabolites level of the blood serum in volunteers at respiration of hypoxic gas mixture containing 8 % of O2 during 25 min was investigated. "

01/01/2020 - "122,129 dives by 10,358 recreational divers were recorded by dive computers from 11 manufacturers in an exploratory study of how dive profile, breathing gas (air or nitrox [N2/O2] mixes), repetitive diving, gender, age, and dive site conditions influenced observed decompression sickness (DCSobs). "
07/01/2018 - "To minimize the risk of decompression sickness (DCS) a 46% nitrox mixture is used. "
09/01/1995 - "A probabilistic model of decompression sickness (DCS) risk based on linear-exponential (LE) kinetics has given the best fit of the human air and nitrox DCS database. "
01/01/1995 - "Evaluation of the risk of decompression sickness in saturated nitrox diving by examination of haemostasis."
07/01/1993 - "Nine volunteer divers served as subjects for nitrox (-a: 60% N2 and 40% O2, and -b: 67.5% N2 and 32.5% O2) and air chamber dives of 20 m/60 min, 30 m/60 min and 40 m/60 min. Venous gas emboli (VGE) were examined after surfacing in a series of nitrox dives and of air dives to compare the risks of decompression sickness (DCS). "

11/01/2014 - "Impairment from gas narcosis when breathing air and enriched air nitrox underwater."
09/01/1999 - "The aim of this study is to compare two narcotic environments; a normobaric narcosis under several percentages of nitrous oxide, and an hyperbaric narcosis under 0.9 MPa of Nitrox (N2O2 mixture). "
03/01/2009 - "Heliox seems to be favored because it causes fewer problems during the recompression of divers, and above all, because nitrox can cause narcosis and contributes nitrogen. "
07/01/1998 - "The aim of this study is to compare, in the Sprague-Dawley rats striatium, changes in extracellular concentrations of Dopamine and its metabolites: Dihydroxyphenylacetic Acid (DOPAC) and Homovanillic Acid (HVA) under a normobaric narcosis (20; 40, and 60% of Nitrous Oxide (N2O)) on one hand, and under 0.9 MegaPascal of Nitrox (Nitrogen Oxygen normoxic mixture) on the other hand. "

08/01/1998 - "Previous studies showed that GHM-10 significantly inhibited the growth of cancer cells both in vitro and in vivo. "
07/01/1998 - "The results showed that GHM-10 exhibited potent inhibitory effect on cancer cells with an IC50 of 2 micrograms.ml-1 approximately. "
08/01/1996 - "This fact explains the experimental and clinical experience, that the breathing hypoxic gas mixture protects the healthy tissue without changes in the radiosensibility of chronic hypoxic tumor tissue."
08/01/1996 - "Between tumor and healthy tissue exists a significant difference regarding changes in the radiobiologic fraction during breathing of hypoxic gas mixture. "
01/01/1991 - "In the tumor tissue the protective effect of GHM-10 was absent."
