Traynor, Timothy R.,Ann Smart, Josephine P. Briggs, and Jurgen Schnermann. Inhibition of macula densastimulated renin secretion by pharmacological blockade of cyclooxygenase-2. Am. J. Physiol. 277 (Renal Physiol. 46): F706–F710, 1999.—Previous results from our laboratory have shown that in the isolated perfused juxtaglomerular apparatus, nonselective inhibitors of cyclooxygenase (COX) activity ...

Gustafsson, Thomas, Peter Andersson, Yun Chen, Jan Olof Magnusson, and Hans J. Arnqvist. Interaction of angiotensin II and the insulin-like growth factor system in vascular smooth muscle cells. Am. J. Physiol. 277 (Heart Circ. Physiol. 46): H499–H507, 1999.—We studied the effects and interactions of ANG II and the insulin-like growth factor (IGF) system in cultured rat aortic smooth muscle cell...

Parthimos, D., D. H. Edwards, and T. M. Griffith. Minimal model of arterial chaos generated by coupled intracellular and membrane Ca21 oscillators. Am. J. Physiol. 277 (Heart Circ. Physiol. 46): H1119–H1144, 1999.—We have developed a mathematical model of arterial vasomotion in which irregular rhythmic activity is generated by the nonlinear interaction of intracellular and membrane oscillators ...

Baldwin, Ann L. Modified hemoglobins produce venular interendothelial gaps and albumin leakage in the rat mesentery. Am. J. Physiol. 277 (Heart Circ. Physiol. 46): H650– H659, 1999.—Cross-linked hemoglobin (aa-Hb) and polyethylene glycol (PEG)-conjugated Hb have both been considered as possible ‘‘blood substitutes.’’ Previously, we showed that PEG-Hb extravasates rapidly in the intestinal mucos...

Richard, C. A., D. M. Rector, R. K. Harper, and R. M. Harper. Optical imaging of the ventral medullary surface across sleep-wake states. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R1239–R1245, 1999.—We hypothesized that spontaneous activity declines over widespread areas of the cat ventral medullary surface (VMS) during rapid eye movement (REM) sleep. We assessed neural and...

Schwartz, Lisa M., Thomas R. Bukowski, James H. Revkin, and James B. Bassingthwaighte. Cardiac endothelial transport and metabolism of adenosine and inosine. Am. J. Physiol. 277 (Heart Circ. Physiol. 46): H1241–H1251, 1999.—The influence of transmembrane flux limitations on cellular metabolism of purine nucleosides was assessed in whole organ studies. Transcapillary transport of the purine nucl...

Dong, Sheng-Jing, Paul S. Hees, Wen-Mei Huang, Sam A. Buffer, Jr., James L. Weiss, and Edward P. Shapiro. Independent effects of preload, afterload, and contractility on left ventricular torsion. Am. J. Physiol. 277 (Heart Circ. Physiol. 46): H1053–H1060, 1999.—Shortening of oblique left ventricular (LV) fibers results in torsion. A unique relationship between volume and torsion is therefore ex...

Speth, Robert C., William T. Barry, M. Susan Smith, and Kevin L. Grove. A comparison of brain angiotensin II receptors during lactation and diestrus of the estrous cycle in the rat. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R904–R909, 1999.—During lactation there are many dramatic alterations in the hypothalamic-pituitary (HP) axis, as well as an increased demand for food ...

Stein, Kenneth M., Jeff Walden, Neal Lippman, and Bruce B. Lerman. Ventricular response in atrial fibrillation: random or deterministic? Am. J. Physiol. 277 (Heart Circ. Physiol. 46): H452–H458, 1999.—The ventricular response in atrial fibrillation is often described as ‘‘chaotic,’’ but this has not been demonstrated in the strict mathematical sense. A defining feature of chaotic systems is sen...
