While long term disturbances in the acid–base balance can disturb the normal growth and development, acute short term, but severe changes in pH, can also be drastic. The body's acid base balance is maintained by different organ systems, including the lungs and the kidneys, along with the intracellular and extracellular buffer systems. A human body’s normal pH ranges from 7.35-7.45. pH and hydro...

Ear lobe blood pHa, PaCo2, PaO2, and O2 saturation (SaO2) were measured in healthy Caucasians and Sherpas at 3400 m (Namche Bazaar, Nepal, n = 4/5), 5050 m (Pyramid Laboratory, Lobuche, Nepal, n = 20/5) and 6450 m (Camp II of Mt Everest, n = 11/7). In the investigated altitude range, pHa increased progressively with altitude from 7.463 +/- 0.005 (mean +/- SE) to 7.496 +/- 0.006 in Caucasians wh...

Thirty four infants were studied; 21 with acute gastroenteritis, dehydration, and metabolic acidosis and 13 who served as controls. All infants with metabolic acidosis and without neurological signs had a normal to near normal cerebrospinal fluid acid base balance, but five with metabolic acidosis and severe neurological signs had cerebrospinal fluid acid base disequilibrium. Acute metabolic ac...

Arterial PCO2, hydrogen ion ([H+]a), and lactate ([L]a) concentrations, rates of metabolic CO2 production (VCO2) and O2 consumption (VO2), and effective alveolar ventilation (Veff) were determined in the lizards Varanus exanthematicus and Iguana iguana at rest and during steady-state treadmill exercise at 35 degrees C. In Varanus, VCO2 increased ninefold and VO2 sixfold without detectable rise ...

background: introducing rctm (research-centered teaching method) by the author, showed the method provokes enthusiasm and anxiety, correlated with cognition . by linking the broaden-and-build theory and emotional intelligence theory, it becomes apparent that the knowledge and use of positive emotions constitute an important skill set for effective functioning. purpose: to investigate the effect...

Disorders of water balance lead either to dehydration or overhydration. Because there is an intimate relationship between water and sodium concentration (water generally following salt), one can distinguish hypotonic, isotonic and hypertonic dehydration and the same for overhydration. The vast majority of water balance disorders are acquired. In this article, the focus is on the inherited disor...

Three-cylinder linear engines are designed to minimize, reduce fuel consumption and pollution. The disadvantages of this type of engine, heavy vibration inherent in them. this study aims to balance Three-cylinder linear engines with a balancing shaft. First, the dynamic analysis of these types of engines identifies unbalanced sources. The results of the dynamic analysis showed that the inertial...
