Ray, Ramesh M., Mary Jane Viar, Qing Yuan, and L. R. Johnson. Polyamine depletion delays apoptosis of rat intestinal epithelial cells. Am. J. Physiol. Cell Physiol. 278: C480–C489, 2000.—The polyamines spermidine, spermine, and their precursor putrescine are essential for cell growth and the regulation of the cell cycle. Recent studies suggest that excessive accumulation of polyamines favors ei...

Hirschfield, Wulf, Melanie R. Moody, William E. O’Brien, Anthony R. Gregg, Robert M. Bryan, Jr., and Michael B. Reid. Nitric oxide release and contractile properties of skeletal muscles from mice deficient in type III NOS. Am. J. Physiol. Regulatory Integrative Comp. Physiol. 278: R95–R100, 2000.—Skeletal muscle constitutively expresses both the type I (neuronal) and type III (endothelial) isof...

Delp, Michael D., Patrick N. Colleran, M. Keith Wilkerson, Matthew R. McCurdy, and Judy MullerDelp. Structural and functional remodeling of skeletal muscle microvasculature is induced by simulated microgravity. Am J Physiol Heart Circ Physiol 278: H1866–H1873, 2000.— Hindlimb unloading of rats results in a diminished ability of skeletal muscle arterioles to constrict in vitro and elevate vascul...

Yang, H. T., and Y. Feng. bFGF increases collateral blood flow in aged rats with femoral artery ligation. Am. J. Physiol. Heart Circ. Physiol. 278: H85–H93, 2000.—We tested the hypothesis that aged animals are as responsive as the young adult animals in expanding collateral vasculature under a similar treatment of basic fibroblast growth factor (bFGF). Two age groups of male Fischer 344 rats (1...

Miller, Kristy J., Deepa Thaloor, Sarah Matteson, and Grace K. Pavlath. Hepatocyte growth factor affects satellite cell activation and differentiation in regenerating skeletal muscle. Am. J. Physiol. Cell Physiol. 278: C174– C181, 2000.—Hepatocyte growth factor (HGF) is the only known growth factor that activates quiescent satellite cells in skeletal muscle. We hypothesized that local delivery ...

Nevière, Rémi, Benoit Guery, Serge Mordon, Farid Zerimech, Stéphane Charré, Francis Wattel, and Claude Chopin. Inhaled NO reduces leukocyte-endothelial cell interactions and myocardial dysfunction in endotoxemic rats. Am J Physiol Heart Circ Physiol 278: H1783–H1790, 2000.— Inhaled nitric oxide (NO) has been shown to have some protective effect in the peripheral distal inflamed vasculature. The...

Da Costa, Maria, Sheldon P. Rothenberg, Easwara Sadasivan, Annette Regec, and Lian Qian. Folate deficiency reduces the GPI-anchored folate-binding protein in rat renal tubules. Am J Physiol Cell Physiol 278: C812–C821, 2000.—A folate-binding protein (FBP) anchored to cell membranes by a glycosyl phosphatidylinositol (GPI) adduct is constitutively expressed in some transformed and cultured cell ...

Faro, Constance J., Roger D. Reidelberger, and Jeffrey M. Palmer. Suppression of food intake is linked to enteric inflammation in nematode-infected rats. Am. J. Physiol. Regulatory Integrative Comp. Physiol. 278: R118– R124, 2000.—Our aim was to investigate the cause-effect relationship between intestinal inflammation induced by infection with enteric stages of Trichinella spiralis and decrease...

Richman, Joshua S., and J. Randall Moorman. Physiological time-series analysis using approximate and sample entropy. Am J Physiol Heart Circ Physiol 278: H2039–H2049, 2000.—Entropy, as it relates to dynamical systems, is the rate of information production. Methods for estimation of the entropy of a system represented by a time series are not, however, well suited to analysis of the short and no...

Osterloh, Kurt, Peter Gaehtgens, and Axel R. Pries. Determination of microvascular flow pattern formation in vivo. Am J Physiol Heart Circ Physiol 278: H1142–H1152, 2000.—Blood flow in microvessels differs significantly from that of red blood cells (RBC) flowing through long, straight glass tubes in vitro. The in vivo situation is characterized by the presence of plasma favoring aggregation, by...
