Thus, the frog heart has yielded fundamental information about ion movements and the primary role of calcium in excitation-contraction, while the frog sartorius has provided the basis of mechanics and energetics in skeletal

The increasing number of active substances isolated from living systems makes it necessary to investigate the effect of any substance not as an independent agent but in interaction with other substances so as to build up the whole picture o

Some Problems of Controlling Spaceshipsby iodoacetic acid and nitrogen. At room temperature, 18–22°C, hypoxia reduced resting heat production from a mean of 30.1 to 18.4 mcal/g muscle · min. Tension development fell from 3.29 to 2.48 (g) and work output under a 1.0 g load decreased from 0.069 to 0.044 g.cm. The mean isometric heat coeffi
