Evidence of calcium phosphate supersaturation in the loop of Henle
American Journal of Physiology-Renal Physiology, 1996 We have used published rat micropuncture data to construct a matrix of ion concentrations along the rat nephron. With an iterative computer model of known ion interactions, we calculated relative supersaturation ratios in all nephron segments. The collecting ducts and urine showed expected supersaturation with stone-forming salts.

Thick ascending limb of the loop of Henle. [PDF]
Clin J Am Soc Nephrol, 2014 The thick ascending limb occupies a central anatomic and functional position in human renal physiology, with critical roles in the defense of the extracellular fluid volume, the urinary concentrating mechanism, calcium and magnesium homeostasis, bicarbonate and ammonium homeostasis, and urinary protein composition.

Development, 2017 The formation of the proper number of nephrons requires a tightly regulated balance between renal progenitor cell self-renewal and differentiation. The molecular pathways that regulate the transition from renal progenitor to renal vesicle are not well ...

In developing mouse kidneys, orientation of loop of Henle growth is adaptive and guided by long-range cues from medullary collecting ducts. [PDF]
J Anat, 2019 The path taken by the loop of Henle, from renal cortex to medulla and back, is critical to the ability of the kidney to concentrate urine and recover water.

Signal transduction in a compliant short loop of Henle. [PDF]
Int J Numer Method Biomed Eng, 2012 SUMMARYTo study the transformation of fluctuations in filtration rate into tubular fluid chloride concentration oscillations alongside the macula densa, we have developed a mathematical model for tubuloglomerular feedback (TGF) signal transduction along the pars recta, the descending limb, and the thick ascending limb (TAL) of a short‐looped nephron ...

New Strategies for Volume Control in Patients with Diabetes Mellitus, a Narrative Review
Pharmaceutics, 2022 Sodium is reabsorbed all along the renal tubules. The positive impacts of sodium-glucose cotransporter-2 inhibitors (SGLT2i), angiotensin receptor neprilysin inhibitor (ARNI) and mineralocorticoid receptor antagonists (MRA) on hard renal and/or cardiac ...

Role of Prox1 in the Transforming Ascending Thin Limb of Henle's Loop during Mouse Kidney Development. [PDF]
PLoS ONE, 2015 The homeobox transcription factor Prox1 is critical to the development of many embryonic organs and tissues, although current understanding of its expression in the developing renal medulla is limited.

Function of thin loops of Henle
Kidney International, 1987 The existence of a steep osmotic gradient in the renal medullary interstitium is the most critical in the formation of concentrated urine [1]. The architectural organization of the renal tubules and blood vessels in the medulla constitutes counterflow systems which are essential for both generating and maintaining high osmotic pressure of the renal ...

Natural Ventilation with Heat Recovery: A Biomimetic Concept
Buildings, 2015 In temperate countries, heat recovery is often desirable through mechanical ventilation with heat recovery (MVHR). Drawbacks of MVHR include use of electric power and complex ducting, while alternative passive heat recovery systems in the form of roof or
