Conrad, Kirk P., Laurie J. Kerchner, and Monique D. Mosher. Plasma and 24-h NOx and cGMP during normal pregnancy and preeclampsia in women on a reduced NOx diet. Am. J. Physiol. 277 (Renal Physiol. 46): F48–F57, 1999.—We tested the hypothesis that nitric oxide (NO) biosynthesis increases during normal human pregnancy and decreases in preeclampsia. The major metabolites of NO, nitrate and nitrit...

Kohzuki, Hisaharu, Hiromi Misawa, Susumu Sakata, Yoshimi Ohga, Hiroyuki Suga, and Miyako Takaki. Energy expenditure by Ba21 contracture in rat ventricular slices derives from cross-bridge cycling. Am. J. Physiol. 276 (Heart Circ. Physiol. 45): H74–H79, 1999.—To clarify the energy-expenditure mechanism during Ba21 contracture of mechanically unloaded rat left ventricular (LV) slices, we measured...

Concannon, Patrick W., V. Daniel Castracane, Richard E. Rawson, and Bud C. Tennant. Circannual changes in free thyroxine, prolactin, testes, and relative food intake in woodchucks, Marmota monax. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R1401–R1409, 1999.— Woodchucks (n 5 12–14/group) with circannual cycles entrained to northern versus southern hemisphere photoperiods wer...

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...
