Degradation and transport of AVP by proximal tubule
American Journal of Physiology-Renal Physiology, 1987High-performance liquid chromatography (HPLC) analysis revealed that [3,4,5-3H-Phe3,Arg8]vasopressin ([3H]AVP) was not degraded by isolated renal brush-border membranes or by a cortical lysosomal fraction in vitro; however, in the presence of 1 mM reduced glutathione, [3H]AVP was degraded by both preparations.

A mathematical model of proximal tubule absorption
The Journal of Membrane Biology, 1979A previous model of the mechanisms of flow through epithelia was modified and extended to include hydrostatic and osmotic pressures in the cells and in the peritubular capillaries. The differential equations for flow and concentration in each region of the proximal tubule were derived. The equations were solved numerically by a finite difference method.

Water permeability and pathways in the proximal tubule
American Journal of Physiology-Renal Physiology, 1983The route of water transport in the proximal tubule could be either transjunctional or transcellular. A transjunctional route is supported by data showing high osmotic-to-diffusive water permeability ratios, the possible correlation of junctional leakiness to ions and nonelectrolytes with water permeability, and solvent drag of nonelectrolytes and ...

In Vitro Proximal Tubule Perfusion Preparation
2003Isolation and perfusion of single nephron segments was first described by Burg et al. (1) in 1966. This technique has allowed us to study both transepithelial and transmembrane transport in individual nephron segments, including the proximal tubule, under carefully controlled circumstances.

Ammonia Production and Secretion by the Proximal Tubule
American Journal of Kidney Diseases, 1989Ammonia production and secretion by the proximal tubule accounts for most of the ammonia that appears in the urine. Rates of ammonia production and net luminal ammonia secretion were measured in isolated perfused mouse proximal tubule segments. This approach combines the in vitro microperfusion technique with a sensitive bioluminescence assay for total
