Abstract:: The production of C¹⁴O₂ metabolized from glucose labeled in specific carbon atoms by homogenates of chick embryonic and adult heart was compared by the radiorespirometric technique. Homogenates of early (two to five days of incubation) embryo hearts were found to utilize the phosphogluconate pathway of glucose catabolism to a greater...

Abstract:: Isocitrate-NADP oxidoreductase activity in mitochondrial and soluble fractions was determined for hearts, livers and brains of chick embryos at various stages of development. One-half to two-thirds of the activity in brain and liver homogenates is located in the soluble fraction. Supernatant activity increases in these organs to a maximum during...

Abstract:: Levels of activity of glucose-6-phosphate- , 6-phosphogluconate- , and isocitric- dehydrogenase were measured in the soluble and particulate fractions of heart, brain and liver at several ages throughout the development of the chick embryo. Compared to isocitric dehydrogenase, levels of glucosesphosphate- , and 6-phosphogluconate- dehydrogenase are generally low. This suggests...

Creator:: Casillas, Edmund Rene
Abstract:: Carnitine, acetylcarnitine, and long-chain acylcarnitine concentrations were determined for heart, brain, and liver of chick embryos during various stages of development. The total carnitine concentration was approximately the same in all three organs and showed only small variations during development. Acetylcarnitine was not detected in any organ until the seventeenth...

Creator:: Austin-Bythell, Suzanne H.
Abstract:: Patterns of nest attendance behavior by breeding birds represent a parent-offspring trade-off in which adults balance self-maintenance with parental care decisions. Incubation, in particular, is of interest because adults must provide an environment suitable for embryonic development through nest-building and contact-incubation. We evaluated how adult incubation constancy and nest visitation...
