As an organism grows, the feel of it changes too. In the initial stages, an embryo takes on an almost fluid-like state that allows its cells to divide and expand. As it matures, its tissues and organs...
Gas production in humans ingesting a soybean flour derived from beans naturally low in oligosaccharides
Soy flour low-oligosaccharide soybeans breath-hydrogen concentration
2016/5/30
Ingestion of soy products may cause excessive
intestinal gas. This gas results from colonic bacterial fermentation
of the indigestible oligosaccharides raffinose and stachyose,
which are present in...
Culture refers to the shared patterns of feelings, beliefs and behaviour that reflect in the way of living in a society. Culture uniquely influence the role functioning or psychosoical wellbeing of pe...
Acoustic Analysis of Breath Sounds as a Surrogate for Gas Exchange Thresholds
Acoustic Analysis Breath Sounds Gas Exchange Thresholds
2015/5/21
Respiratory gas exchange threshold measurements are a reference standard for measuring sustainable exercise capacity (McLellan and Skinner, 1981). A recent consensus report suggested that ‘threshold b...
The Difference in Respiratory and Blood Gas Values During Recovery After Exercise With Spontaneous Versus Reduced Breathing Frequency
Constant load test reduced breathing frequency recovery respiratory parameters oxygen saturation blood gas
2015/4/23
Extrapolation from post-exercise measurements has been used to estimate respiratory and blood gas parameters during exercise. This may not be accurate in exercise with reduced breathing frequency (RBF...
Comparison of metabolic gas analysis between a standard laboratory system and a portable device

2015/4/23
The recent development of portable metabolic gas analysis systems gives scientists the capability of measuring physiological data, including oxygen consumption, associated with multi-directional movem...
Very Few Exercise-Induced Arterialized Gas Bubbles Reach the Cerebral Vasculature
SCUBA DIVING GAS EMBOLI GRADING ARTERIAL GAS EMBOLI INTRAPULMONARY ATERIAL-VENOUS ANASTOMOSES
2017/4/20
Introduction: Arterialization of venous gas emboli (VGE) formed after surfacing from SCUBA diving can become arterial gas emboli (AGE) through intrapulmonary arterial-venous anastomoses that open with...
Air-Standard Aerothermodynamic Analysis of Gas Turbine Engines With Wave Rotor Combustion
Air-Standard Aerothermodynamic Gas Turbine Engines
2014/11/13
The wave rotor combustor can significantly improve gas turbine engine performance by implementing constant-volume combustion. The periodically open and closed combustor complicates thermodynamic analy...
Wave Cycle Design for Wave Rotor Gas Turbine Engines with Low NOx emissions
Wave Cycle Design Wave Rotor Gas Turbine Engines
2014/11/13
The wave rotor is a promising means of pressure-gain for gas turbine engines. This paper examines novel wave rotor topping cycles that incorporate low-NOx combustion strategies. This approach combines...
消痈溃得康对乙酸致胃溃疡模型大鼠血清GAS及MTL含量的影响
