Energy metabolism, nitrogen balance, and substrate utilization in critically ill children
substrate oxidation pediatrics mechanical ventilation
2016/6/14
Critically ill patients are characterized by a hypermetabolic
state, a catabolic response, higher nutritional needs,
and a decreased capacity for utilization of parenteral substrate.
Guar gum does not impair the absorption and utilization of dietary nitrogen but affects early endogenous urea kinetics in humans
Guar gum dietary nitrogen urea kinetics
2016/6/14
Viscous gums enhance viscosity in the upper gastrointestinal
lumen, quickly disturbing motility and promoting
fluid secretion.

AN INVESTIGATION OF OXIDES OF NITROGEN IN METROPOLITAN TEHRAN
INVESTIGATION OXIDES NITROGEN METROPOLITAN TEHRAN
2009/12/30
Planning of air pollution control programs need knowledge of pollutants emitting sources; the Department of Environmental Health, School of Public Health, Tehran University, performed an air monitorin...
The effect of ambient pressure on inert gas elimination during decompression was investigated using human subjects breathing air in a dry hyperbaric chamber. This was done by measuring nitrogen recove...
Reversal of nitrogen narcosis in rats by helium pressure
nitrogen narcosis nitrogen helium animal rat
2009/7/20
Changes in operant behavior were obtained for rats breathing nitrogen, helium, and both gases combined. Exposure to 12.9 ATA of nitrogen (O2 maintained at normobaric value of 0.2 ATA) produced complet...

In an attempt to determine the roles of nitrogen, oxygen, and carbon dioxide in compressed-air narcosis, the effects on performance (mental function and manual dexterity) of adding CO2 in various conc...
Nitrogen elimination during steady-state hyperbaric exposures
Nitrogen elimination human decompression
2009/7/17
Nitrogen elimination was measured in six divers during steady-state exposures in an oxygen-nitrogen atmosphere at 1, 2, and 3 ATA using both oxy-helium and pure O2 as washout gases. This was accomplis...
