The Edinger-Westphal nucleus (EW) is a brain region that has recently been implicated as an important novel neural target for ethanol. Thus, the EW is the only brain region consistently showing elevated c-Fos expression following both voluntary and involuntary ethanol administration. Ethanol-induced c-Fos expression in the EW has been shown to occur in urocortin I-positive neurons. Moreover, pr...

Peripheral CRF inhibits gastric emptying and stimulates colonic motor function in rats. We investigated the role of CRF1 and CRF2 receptors in i.p. CRF-induced alterations of gut transit in conscious mice using selective CRF1 and CRF2 ligands injected i.p. Gastric emptying 2 h after ingestion of a solid chow meal and colonic transit (time to expel a bead inserted into the distal colon) were det...

IT IS HAS BEEN OVER TWO DECADES since Murry and colleagues (15) published their seminal study describing ischemic preconditioning, a phenomenon whereby brief antecedent periods of ischemia-reperfusion profoundly protect the heart against a subsequent lethal period of ischemia and reperfusion. This intrinsic cardioprotective mechanism has been demonstrated in every animal tested, including human...

CONTROL OF FOOD INTAKE is complex, involving multiple interconnected pathways and signal elements. A paper by Wang and Kotz (11) in this issue of the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology illustrates some of the complexity and carries implications for how the regulation of food intake is integrated into the daily life of humans and other animals. Wang...
