Carbon dioxide and vitamin D effects on calcium metabolism in nuclear submariners:a review
submarine CO2 carbon dioxide human chamber
2009/7/17
Studies in nuclear submariners show that calcium excretion falls rapidly to 50% of pre-patrol levels during long patrols and remains low for many weeks after return to fresh air. This has previously b...
Calcium, magnesium, and phosphorus metabolism, and parathyroid-calcitonin function during prolonged exposure to elevated CO2 concentrations on submarines
submarine CO2 carbon dioxide
2009/7/17
Studies of calcium and phosphorus metabolism and acid-base balance were carried out on three Fleet Ballistic Missile (FBM) submarines during prolonged exposure to elevated concentrations of CO2. The a...
Effect of intermittent exposure to 3% CO2 on respiration,acid-base balance,and calcium-phosphorus metabolism
CO2 carbon dioxide hydrogen acclimatization air
2009/7/17
One subject was exposed for six days to increasing levels of CO2, rising at a constant rate from 0.03 to 3.0% CO2 within a 15-h period followed by 9 h of air breathing. To assess acid-base parameters,...
Effect of pressure on the release of endogenous dopamine from rat striatum and the role of sodium-calcium exchange
model animal rat High Pressure Neurological Syndrome
2009/7/8
Exposure to environmental pressures in excess of 20 atm abs can precipitate a hyperexcitability state known as high pressure neurologic syndrome (HPNS). Little is known about the underlying neurochemi...
Pressure antagonism of nitrous oxide depression of intracellular calcium in a neuroblastoma cell line
human Pressure antagonism nitrous oxide
2009/6/8
While the ability of increased pressure to reverse anaesthesia has been well documented, the cellular or molecular mechanism(s) responsible for their mutual antagonism have remained elusive.
