Hyperoxic ventilation, used to prevent hypoxemia during potential periods of hypoventilation, has been reported to paradoxically decrease whole body oxygen consumption (Vo(2)). Reduction in nutritive blood flow due to oxygen radical production is one…
Circulatory indirect calorimetry (CIC) is a potentially useful method to assess the energy requirements of critically ill patients. Unlike respiratory indirect calorimetry (RIC), which measures oxygen utilization from inhaled and exhaled gases, CIC…
Odontochelys semitestacea, the oldest known turtle, from the Late Triassic of China, shows a pathology. Sharply defined, focal depressions were noted on the articular surfaces of both humeri, documenting avascular necrosis. Diving habits of Mesozoic…
