Villalobos, Alice R., Judith T. Parmelee, and J. Larry Renfro. Choline uptake across the ventricular membrane of neonate rat choroid plexus. Am. J. Physiol. 276 (Cell Physiol. 45): C1288–C1296, 1999.—The uptake of [3H]choline from the cerebrospinal fluid (CSF) side of the rat neonatal choroid plexus was characterized in primary cultures of the choroidal epithelium grown on solid supports. Cell-...

Currie, Suzanne, Bruce L. Tufts, and Christopher D. Moyes. Influence of bioenergetic stress on heat shock protein gene expression in nucleated red blood cells of fish. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R990–R996, 1999.—The physiological and biochemical signals that induce stress protein (HSP) synthesis remain conjectural. In this study, we used the nucleated red bl...

Boulton, M., M. Flessner, D. Armstrong, R. Mohamed, J. Hay, and M. Johnston. Contribution of extracranial lymphatics and arachnoid villi to the clearance of a CSF tracer in the rat. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R818–R823, 1999.—The objective of this study was to determine the relative roles of arachnoid villi and cervical lymphatics in the clearance of a cereb...

Moran, Daniel S., Yair Shapiro, Arie Laor, Sharona Izraeli, and Kent B. Pandolf. Can gender differences during exercise-heat stress be assessed by the physiological strain index? Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1798–R1804, 1999.—A physiological strain index (PSI) based on rectal temperature (Tre) and heart rate (HR) was recently suggested to evaluate exercise-he...

Good, David W., Thampi George, and Donna H. Wang. Angiotensin II inhibits HCO3 2 absorption via a cytochrome P-450-dependent pathway in MTAL. Am. J. Physiol. 276 (Renal Physiol. 45): F726–F736, 1999.—The role of ANG II in the regulation of ion reabsorption by the renal thick ascending limb is poorly understood. Here, we demonstrate that ANG II (1028 M in the bath) inhibits HCO3 2 absorption by ...

Ito, Osamu, and Richard J. Roman. Regulation of P-450 4A activity in the glomerulus of the rat. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1749–R1757, 1999.—We recently reported that an enzyme of the cytochrome P-450 4A family is expressed in the glomerulus, but there is no evidence that 20-hydroxyeicosatetraenoic acid (20-HETE) can be produced by this tissue. The purpose ...

Farge, Emmanuel, David M. Ojcius, Agathe Subtil, and Alice Dautry-Varsat. Enhancement of endocytosis due to aminophospholipid transport across the plasma membrane of living cells. Am. J. Physiol. 276 (Cell Physiol. 45): C725– C733, 1999.—Formation of intracellular vesicles is initiated by membrane budding. Here we test the hypothesis that the plasma membrane surface area asymmetry could be a dr...

Physiol. 276 (Cell Physiol. 45): C734– C746, 1999.—This study was designed to demonstrate the presence of epidermal growth factor (EGF) in the rat exorbital lacrimal gland. EGF precursor gene transcription was demonstra...

Frame, Mary D. S. Conducted signals within arteriolar networks initiated by bioactive amino acids. Am. J. Physiol. 276 (Heart Circ. Physiol. 45): H1012–H1021, 1999.—Our purpose was to determine the specificity of L-arginine (L-Arg)induced conducted signals for intravs. extracellular actions of L-Arg. Diameter and red blood cell velocities were measured for arterioles [18 6 1.6 (SE) μm] in the c...
