Fang, Zhiwu, Scott H. Carlson, Ning Peng, and J. Michael Wyss. Circadian rhythm of plasma sodium is disrupted in spontaneously hypertensive rats fed a high-NaCl diet. Am J Physiol Regulatory Integrative Comp Physiol 278: R1490–R1495, 2000.—High-NaCl diets elevate arterial pressure in NaCl-sensitive individuals, and increases in plasma sodium may trigger this effect. The present study tests the ...

Gupta, Gaurav, Li She, Xiao-Hui Ma, Xiao-Man Yang, Meizhu Hu, Jane A. Cases, Patricia Vuguin, Luciano Rossetti, and Nir Barzilai. Aging does not contribute to the decline in insulin action on storage of muscle glycogen in rats. Am. J. Physiol. Regulatory Integrative Comp.

Covasa, Mihai, Robert C. Ritter, and GilbertA. Burns. NMDA receptor participation in control of food intake by the stomach. Am J Physiol Regulatory Integrative Comp Physiol 278: R1362–R1368, 2000.—We previously reported that MK801 (dizocilpine), an antagonist of N-methyl-D-aspartate (NMDA)-type glutamate receptors, increased meal size and duration in rats. MK-801 did not increase sham feeding o...

Kanellis, John, Scott Fraser, Marina Katerelos, and David A. Power. Vascular endothelial growth factor is a survival factor for renal tubular epithelial cells. Am J Physiol Renal Physiol 278: F905–F915, 2000.—Vascular endothelial growth factor (VEGF) acts primarily as an endothelial cell mitogen via the ‘‘endothelial cell-specific’’ receptors VEGFR-1 (flt-1) and VEGFR-2 (flk-1/KDR). Only a few ...

Pavlova,Anna, Hiroyuki Sakurai, Baudouin Leclercq, David R. Beier, Alan S. L. Yu, and Sanjay K. Nigam. Developmentally regulated expression of organic ion transporters NKT(OAT1), OCT1, NLT(OAT2), and Roct. Am J Physiol Renal Physiol 278: F635–F643, 2000.—Several xenobiotic (organic cation and anion) transporters have recently been identified, although their endogenous substrates, if such exist,...

Lau, Sandy S., Tina M. Griffin, and Ruben Mestril. Protection against endotoxemia by HSP70 in rodent cardiomyocytes. Am J Physiol Heart Circ Physiol 278: H1439– H1445, 2000.—Clinical and experimental studies have shown that myocardial dysfunction is an early event during endotoxemia or septic shock. Several reports have shown that rodents submitted to a mild heat shock become resistant to lipop...

Buxton, Orfeu M., Mireille L’Hermite-Balériaux, Fred W. Turek, and Eve Van Cauter. Daytime naps in darkness phase shift the human circadian rhythms of melatonin and thyrotropin secretion. Am. J. Physiol. Regulatory Integrative Comp.

Song, Xiaowei, and Benjamin Rusak. Acute effects of light on body temperature and activity in Syrian hamsters: influence of circadian phase. Am J Physiol Regulatory Integrative Comp Physiol 278: R1369–R1380, 2000.—Light exposure at night causes an acute increase in human body temperature, which normally falls during the night. This change is largely attributable to the suppression by light of t...
