A comparison of respiratory function in divers breathing with a mouthpiece or a full face mask
exercise equipment mouthpiece full face mask respiratory dead space
2009/7/14
A comparison was made of respiratory function in submersed divers breathing with either a mouthpiece or a full face mask while exposed to varying depths (15 and 190 fsw), exercise loads (0-175 W), and...
Effects of breathing-gas pressure on pulmonary function and work capacity during immersion
exercise pulmonary narcosis hyperbaric air immersion work of breathing
2009/7/9
Upright immersion induces respiratory mechanical changes that may impair pulmonary function during hyperbaric exercise. To evaluate this, 10 divers performed an incremental cycling protocol while imme...

2009/6/30
The protective roles of low-dose dopamine and mannitol infusion in the renal function of patients undergoing cardiovascular surgery were compared in 36 patients by measuring urine N-acetyl-b-D- glucos...
Evaluation of Phagocytic Function of The Spleen After Splenic Artery Ligation in Secondary Hypersplenism
Hypersplenism Splenic vein ligation Splenic artery ligation Phagocytosis Fibrosis
2009/6/25
The aim of this study was to investigate the effects of splenic artery ligation on the phagocytic functions and morphology of the spleen in rabbits in which secondary hypersplenism was induced by sple...
Insulin Sensitivity,b Cell Function and Serum Lipid Levels in Helicobacter Pylori Positive,Non-Obese,Young Adult Males
Helicobacter pylori insulin sensitivity
2009/6/23
It is not clear whether Helicobacter pylori (Hp) infection affects insulin levels and insulin sensitivity. We aimed to determine insulin sensitivity and beta cell function, and to evaluate serum lipid...
Effects of Acute Fenthion Toxicity on Liver and Kidney Function and Histology in Rats
Fenthion butyrylcholinesterase hepatotoxicity nephrotoxicity
2009/6/17
Aim: The aim of this study was to investigate the dose-related effects of fenthion on the liver and kidney and the correlation between severity of organ damage and serum butyrylcholinesterase (BChE) e...
Effect of hyperbaric and normobaric oxygen on pulmonary endothelial cell function
pulmonary animal rat
2009/6/12
The effect of prior exposure to raised partial pressures of oxygen on pulmonary endothelial cell function was assessed in the isolated perfused rat lung preparation. Prolonged exposure to both 1 bar (...
Moderate hypercapnia:cardiovascular function and nitrogen elimination
CO2 carbon dioxide nitrogen elimination hypercapnia nitrogen cardiovascular
2009/6/12
Elevated carbon dioxide concentrations frequently encountered in diving operations may have cardiovascular effects. If so, changes in nitrogen loading and elimination may be induced. To study this pos...
Use of the Wavelength Differential Method to Eliminate Baseline Drift in the Assessment of Cerebral Function Using NIRS
NIRS absorbance difference by wavelength Wiener filter cerebral oxygenation cerebral function
2009/6/10
This paper focuses on a method to eliminate the artifacts and level the baseline in the estimation. At first, we examined the appropriateness of the two-component model generally used in NIRS estimati...
Effects of venous gas microemboli on pulmonary gas transfer function
