Functional responses of diaphragm muscle in the rat to varying PCO2 levels and helium content in hyperbaric atmospheres
diaphragm carbon dioxide helium hyperbaric animal rat
2009/7/20
Functional responses of diaphragm muscle in the rat to varying PCO2 levels and helium content in hyperbaric atmospheres.
Reduction of the incidence of decompression sickness in rats by smooth-muscle activating factor (SMAF)
decompression
2009/7/17
Normal rats were injected with a smooth-muscle activating factor (SMAF) to examine the dose-response relationshio of SMAF to the incidence of decompression sickness. After injections of saline or 1.0,...
Muscle preparations from rat atria were hydraulically compressed in circulating Tris-buffered solution kept at 37 degrees C. Spontaneously beating preparations decreased their beating frequency with 3...
Combined effect of beating rate and hydrostatic pressure on excitation in cardiac muscle
cardiac heart rate hydrostatic animal dog
2009/7/16
Canine cardiac Purkinje fibers stimulated at frequencies from 1-4 Hz were exposed to hydrostatic pressures of 1 and 150 ATA. Both increases in stimulation frequency and pressure slowed conduction and ...
Effects of dietary lipids on frequency and force in atrial muscle at 10 MPa
diet lipid cardiac animal rat
2009/7/14
Spontaneously beating atrial preparations, from rats fed different lipid diets, were compressed to 10 MPa. The following observations were made: Different lipid diets altered the ratio of omega-6/omeg...
Effect of benzazole-related centrally acting muscle relaxants on HPNS
benzazole high pressure nervous syndrome animal mice
2009/7/14
A series of benzazole-related, centrally acting muscle relaxants, comprising benzimidazole, chlorzoxazone, and zoxazolamine, were found to give substantial protection against the tremors and convulsio...
Skeletal muscle metabolic enzymes are altered by hyperbaric oxygenation treatments
HBO Skeletal muscle metabolic enzymes rabbit animal
2009/6/12
To test whether repeated HBO exposures would increase activity of skeletal muscle metabolic enzymes, 27 rabbits (3 groups) were exposed 90 min/day, 5 days/wk to either 100% O2 at 243 kPa (HBO), 100% O...
Muscle swelling in divers may represent a previously unreported form of decompression sickness. It shows marked, brawny swelling of skeletal muscle which clinically most suggests muscular lymphedema i...
Effects of hyperbaric (6 ATA) pressure on voluntary and evoked skeletal muscle contractile properties
Atmospheric Pressure Compressive Strength human Muscle Contraction
2009/6/4
The objective of this study was to investigate the effect of 6 atmospheres of pressure (ATA) on plantar flexors' (PF) voluntary force and activation, force-frequency characteristics, and rate of torqu...
Effect of hyperbaric oxygen therapy on exercise-induced muscle soreness
Creatine Kinase blood Exercise physiology human Hyperbaric Oxygenation
2009/6/4
The purpose of this study was to examine the effects of HBO2 therapy on exercise-induced muscle soreness. Subjects (n = 6 male and 10 female university student volunteers) were randomly divided into a...
Effects of respiratory muscle training on respiratory CO2 sensitivity in SCUBA divers
DIVERS ventilation carbon dioxide CO2 production hypoventilation hyperventilation respiratory respiratory muscle performance CO2 retainers
2009/6/2
Typically, ventilation is tightly matched to CO2 production. However, in some cases CO2 is retained (SCUBA diving). One factor behind hypoventilation in divers may be low respiratory CO2 sensitivity. ...
'In situ' high pressure confocal Ca(2+)-fluorescence microscopy in skeletal muscle:a new method to study pressure limits in mammalian cells
high pressure microscopy in situ confocal laser scanning microscopy PRESSURE Ca2+ homeostasis mammalian skeletal muscle fluorescence mitochondria
2009/6/2
We combined 'in situ' high pressure microscopy with confocal laser scanning microscopy to directly study Ca2+ homeostasis in intact mammalian (murine) skeletal muscle fibres during high pressure expos...
Resistive respiratory muscle training improves and maintains endurance swimming performance in divers
