Hyperfiltration and glomerulosclerosis

Seminars in Nephrology, 2003
Nearly 70 years ago, the association between reduction in renal mass and subsequent glomerular injury was established. Later the pathologic changes were attributed to adaptive hemodynamic changes in the residual nephrons. This relationship seems to exist in a number of experimental animal species, as well as humans.

Mechanism of hyperfiltration

Clinical Queries: Nephrology, 2012
Abstract Glomerular hyperfiltration associated with early diabetes mellitus (DM) is a risk factor for the development of progressive diabetic nephropathy. Though pathogenesis of hyperfiltration is not well-known but has been attributed to glomerular hemodynamic and tubular factors.

Hyperfiltration of Saccharide Solutions

Berichte der Bunsengesellschaft für physikalische Chemie, 1973
AbstractFor a membrane system near equilibrium, the thermodynamics of irreversible processes yields an expression relating the filtration coefficient of the solute, its chemical flux and the volume flow through the membrane. This relation was checked experimentally and found to be correct for the investigated membrane system.

Glomerular Hyperfiltration in Human Diabetes

Diabetes Care, 1994
The presence of the characteristic early glomerular hyperfiltration seenin diabetes was originally suggested long ago by Cambier (1), indeed a few years before the well-known studies by Kimmelstiel and Wilson (2) that documented the typical glomerular structural lesions in diabetic patients. Brenner (3,4), in his breakthrough glomerular hyperfiltration-

Glomerular hyperfiltration in excess weight adolescents

Nigerian Journal of Clinical Practice, 2019
Childhood overweight/obesity burden is on the rise worldwide. Obesity affects virtually all organs. In the kidney, glomerular hyperfiltration that manifests as elevated glomerular filtration rate is a frequent manifestation in obesity. This adaptive renal manifestation to excess metabolic demand on the kidney, in children, has been studied mainly in ...

Sodium restriction corrects hyperfiltration of diabetes

American Journal of Physiology-Renal Physiology, 1988
The effect of a low-sodium diet on the abnormal glomerular hemodynamics of early diabetes was studied in rats. Starting 5 to 7 days after onset of streptozotocin-induced insulin-dependent diabetes mellitus (IDDM), rats were fed a low-sodium diet for 4-5 days. Normal rats fed the same diet served as controls. Micropuncture measurements were made during

Hyperfiltration of laundry wastes☆

Water Research, 1974
Abstract Hyperfiltration (reverse osmosis) with dynamically formed hydrous Zr(IV) oxide-polyacrylate membranes removed ∼98 per cent of the organic carbon from effluents from two commercial laundries. The filtrate was clear and essentially colorless to over 85 per cent water recovery. Fluxes were mostly between 50 and 100 (U.S.) gal day −1 ft −2 at

Laboratory experiments with hyperfiltration membranes

Desalination, 1980
Abstract The operation properties of hyperfiltration membranes are representable by various model concepts. The different mathematical relationships that are based on the respective models correspond to the known phenomenological ones and are suitable for describing the throughput through these membranes as well as their separation behaviour within a

Material transport in hyperfiltration

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1983
Transport equations for hyperfiltration, based on the frictional formalism of non-equilibrium thermodynamics, are derived for a gel-type membrane. Taking the concentration distribution in the membrane into account and allowing for possible non-equilibrium partition effects at the membrane boundaries, the flow equations are integrated and equations for ...

Streaming Potentials During Hyperfiltration

1971
The theoretical and experimental studies of hyperfiltration of electrolytes through charged membranes indicate the important role of the potentials developed across the membranes. These potentials were measured directly with a pair of reversible electrodes under conditions of stationary hyperfiltration.
