Abreu-Martin, Maria T., Andrew A. Palladino, Mary Faris, Nelson M. Carramanzana, André E. Nel, and Stephan R. Targan. Fas activates the JNK pathway in human colonic epithelial cells: lack of a direct role in apoptosis. Am. J. Physiol. 276 (Gastrointest. Liver Physiol. 39): G599–G605, 1999.—Fas is expressed constitutively by colonic epithelial cells, and its ligand is expressed by intraepithelia...

Kriston, Tünde, Rocco C. Venuto, Christine Baylis, and György Losonczy. Hemodynamic and renal effects of U-46619, a TXA2/PGH2 analog, in late-pregnant rats. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R831–R837, 1999.—The vasoconstrictor effects of pressor agents are attenuated during pregnancy. Thromboxane A2 (TXA2) is produced in great quantities during hypertension in pre...

Huang, Qin-Heng, Victor J. Hruby, and Jeffrey B. Tatro. Role of central melanocortins in endotoxin-induced anorexia. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R864–R871, 1999.—Inflammation and microbial infection produce symptoms, including fever, anorexia, and hypoactivity, that are thought to be mediated by endogenous proinflammatory cytokines. Melanocortins are known to...

Taylor, Ryan P., M. Brennan Harris, and Joseph W. Starnes. Acute exercise can improve cardioprotection without increasing heat shock protein content. Am. J. Physiol. 276 (Heart Circ. Physiol. 45): H1098–H1102, 1999.—The aim of this study was to determine the effects of acute bouts of exercise on myocardial recovery after ischemia and heat shock protein expression.
