Marples, David, Jørgen Frøkiaer, and Søren Nielsen. Long-term regulation of aquaporins in the kidney. Am. J. Physiol. 276 (Renal Physiol. 45): F331–F339, 1999.—The discovery of the aquaporin family of water channels has greatly improved our understanding of how water crosses epithelial cells, particularly in the kidney. The study of the mechanisms involved in the regulation of collecting duct w...

Michaud, David, Hymie Anisman, and Zul Merali. Capsaicin-sensitive fibers are required for the anorexic action of systemic but not central bombesin. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1617–R1622, 1999.—Bombesin (BN) suppresses food intake in rats whether given centrally or systemically.

Physiol. 45): H913–H917, 1999.— Recent studies have suggested that the increased ventilatory response during exercise in patients with chronic heart failure was related to the activation of muscle metaborecept...

McLean, Lee Anne, Shaheen Zia, Fredric A. Gorin, and Peter M. Cala. Cloning and expression of the Na1/H1 exchanger from Amphiuma RBCs: resemblance to mammalian NHE1. Am. J. Physiol. 276 (Cell Physiol. 45): C1025– C1037, 1999.—The cDNA encoding the Na1/H1 exchanger (NHE) from Amphiuma erythrocytes was cloned, sequenced, and found to be highly homologous to the human NHE1 isoform (hNHE1), with 79...

Physiol. 276 (Cell Physiol. 45): 1046–C1052, 1999.—Increased epithelial permeability is associated with intestinal inflammation, but there is little information on factors that regulate barrier function in the absence of or bef...

Segar, Jeffrey L., Oliva J. Smith, and Aaron T. Holley. Mechanoand chemoreceptor modulation of renal sympathetic nerve activity at birth in fetal sheep. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1295– R1301, 1999.—Physiological responses at birth include increases in heart rate (HR), blood pressure, sympathetic nerve activity, and circulating vasoactive peptides. The fact...

setting, and an increasing number of emergency providers use point-of-care biliary sonography to rapidly evaluate symptomatic patients for the presence of cholelithiasis and its complications. Evaluation of elderly patients with suspected biliary sepsis is frequently complicated by altered mental status. In contrast to younger patients, sepsis from ascending cholangitis may be accompanied by at...
