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...

MacNeil, B. J., A. H. Jansen, A. H. Greenberg, and D. M. Nance. Effect of acute adrenalectomy on sympathetic responses to peripheral lipopolysaccharide or central PGE2. Am J Physiol Regulatory Integrative Comp Physiol 278: R1321–R1328, 2000.—The impact of plasma corticosterone levels on the sympathetic nervous system (SNS) response to intravenous lipopolysaccharide (LPS) or intracerebroventricu...

Bluhm, Wolfgang F., Evangelia G. Kranias, Wolfgang H. Dillmann, and Markus Meyer. Phospholamban: a major determinant of the cardiac force-frequency relationship. Am. J. Physiol. Heart Circ. Physiol. 278: H249–H255, 2000.—The cardiac force-frequency relationship has been known for over a century, yet its mechanisms have eluded thorough understanding. We investigated the hypothesis that phosphola...

Kahlke, Volker, Martin K. Angele, Martin G. Schwacha, Alfred Ayala, William G. Cioffi, Kirby I. Bland, and Irshad H. Chaudry. Reversal of sexual dimorphism in splenic T lymphocyte responses after traumahemorrhage with aging. Am. J. Physiol. Cell Physiol. 278: C509–C516, 2000.—Previous studies have demonstrated that hemorrhagic shock produces immunodepression in young male mice, whereas the immu...

Hulme, J. T., and C. H. Orchard Effect of acidosis on transient outward potassium current in isolated rat ventricular myocytes. Am. J. Physiol. Heart Circ. Physiol. 278: H50–H59, 2000.—The effect of acidosis on the transient outward K1 current (Ito) of rat ventricular myocytes has been investigated using the perforated patch-clamp technique. When the holding potential was 280 mV, depolarizing p...

McNulty, Patrick H. Comparison of local and systemic effects of insulin on myocardial glucose extraction in ischemic heart disease. Am. J. Physiol. Heart Circ. Physiol. 278: H741–H747, 2000.—Physiological increases in circulating insulin level significantly increase myocardial glucose uptake in vivo. To what extent this represents a direct insulin action on the heart or results indirectly from ...

Donahue, Henry J., Zhongyong Li, Zhiyi Zhou, and Clare E. Yellowley. Differentiation of human fetal osteoblastic cells and gap junctional intercellular communication. Am. J. Physiol. Cell Physiol. 278: C315–C322, 2000.—Gap junctional channels facilitate intercellular communication and in doing so may contribute to cellular differentiation. To test this hypothesis, we examined gap junction expre...

Heaps, Cristine L., Michael Sturek, Julie A. Rapps, M. Harold Laughlin, and Janet L. Parker. Exercise training restores adenosine-induced relaxation in coronary arteries distal to chronic occlusion. Am J Physiol Heart Circ Physiol 278: H1984–H1992, 2000.—We previously reported that canine collateral-dependent coronary arteries exhibit impaired relaxation to adenosine but not sodium nitroprussid...

Zhu, Peili, Li Lu, Ya Xu, Clifford Greyson, and Gregory G. Schwartz. Glucose-insulin-potassium preserves systolic and diastolic function in ischemia and reperfusion in pigs. Am. J. Physiol. Heart Circ. Physiol. 278: H595–H603, 2000.—Clinical and experimental studies have suggested benefit of treatment with intravenous glucose-insulin-potassium (GIK) in acute myocardial infarction. However, pati...
