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 oxidative metabolism of drugs by mouse hepatic microsomes
animal mice oxidative metabolism hepatic microsomes delta-9-tetrahydrocannabinol Cannabis drug
2009/7/14
The metabolism of antipyrene and delta-9-tetrahydrocannabinol (delta-9-THC) was studied in vitro with mouse liver supernatant and 105,000 g microsomes at 450 atm pressure. No significant change in rat...
Effects of the submarine environment on renal-stone risk factors and vitamin D metabolism
submarine nephrolithiasis vitamin D metabolism renal stone sunlight deprivation
2009/6/12
The effects of total sunlight deprivation on urinary risk factors for nephrolithiasis and vitamin D metabolism were studied in 20 healthy male subjects. Blood and 24-h urine samples were collected bef...
Bone composition and metabolism after hyperbaric oxygenation in rats with 1-hydroxyethylidene-1,1-bisphosphonate-induced rickets
HBO hyperbaric Bone composition animal rat
2009/6/8
We examined bone composition and metabolism after hyperbaric oxygenation (HBO) in Wistar rats with 1-hydroxyethylidene-1, 1-bisphosphonate (HEBP)-induced rickets. Twenty rats at 4 wk of age were divid...
Pressure and temperature interactions on aerobic metabolism in migrating silver eels: results in vitro

2009/6/2
The European eel (Anguilla anguilla) migrates (6000 km) from European coast towards the supposed spawning area: the Sargasso Sea. This intensive and sustained swimming activity is performed without fe...
