desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), we found the chicken heterophils teemed with avian beta defensin 2 (AvBD2) isoform. The heterophils play a crucial role in innate immunity defending against microbial pathogens. Because heterophils undergo activation through their membrane bound “Toll-like receptors (TLR)”that recognize “pathogen associated molecules,” we wa...

Nitrogen Metabolism in the Chick Embryo

To determine the nature of the food material burned by the developing chick embryo use has been made of two methods in the past. The validity of the information to be derived from one of them-the measurement of the respiratory quotient-we shall presently have occasion to examine. The second and more reliable method is based upon direct analysis of the egg contents at various stages of developme...

Metabolism of the Black Snake Embryo

Bohr (1904) reported CO2 production of an embryo of Natrix natrix, weighing 0-46 g., to be 120 mm./g./hr. at 14-2° C ; the CO2 produced at 28 0 C. was 3 times that at 15 C , and production by a newly hatched snake at 15° C. was approximately 90 mm./g./hr. Other data are given, but they are not related to stage of development, and oxygen utilization was not measured. Zarrow & Pomerat (1937) made...

Parallels between embryo and cancer cell metabolism.

A key characteristic of cancer cells is the ability to switch from a predominantly oxidative metabolism to glycolysis and the production of lactate even when oxygen is plentiful. This metabolic switch, known as the Warburg effect, was first described in the 1920s, and has fascinated and puzzled researchers ever since. However, a dramatic increase in glycolysis in the presence of oxygen is one o...
