p38 Mitogen-activated Protein Kinase Regulates Oscillation of Chick Pineal Circadian Clock [PDF]
, 2003 Extracellular signal-regulated kinase (ERK) and p38 are members of the mitogen-activated protein kinase (MAPK) family, and in some cases these kinases serve for closely related cellular functions within a cell. In a wide range of animal clock structures,

Studies of the Chick Edema Disease
Poultry Science, 1973 Abstract Based on recently obtained analytical information, calculations were made to ascertain the toxic effects of chick edema factor (CEF) preparations for the intact day-old chick, the developing chick embryo, and the monkey. Results indicate that CEF, principally polychlorodibenzo-p-dioxins, elicits toxic responses in these experimental animals.
