Urinary extracellular vesicular release of aquaporins in patients with renal transplantation
BMC Nephrology, 2019 Background Diuresis has been observed within a week following renal transplantation, suggesting that the procedure causes acute disturbance of renal water homeostasis. Aquaporin (AQP) 1 and AQP2, important proteins for renal water reabsorption, have been

Controlled aquaporin-2 expression in the hypertonic environment [PDF]
American Journal of Physiology-Cell Physiology, 2009 The corticomedullary osmolality gradient is the driving force for water reabsorption occurring in the kidney. In the collecting duct, this gradient allows luminal water to move across aquaporin (AQP) water channels, thereby increasing urine concentration. However, this same gradient exposes renal cells to great osmotic challenges.

Neuromyelitis optica - an update: 2007-2009
Annals of Indian Academy of Neurology, 2009 Neuromyelitis optica is an inflammatory demyelinating disorder of the central nervous system. The discovery of a specific antibody (NMO IgG /aquaporin-4 antibody) in patients with this condition has led to a marked revival of research on the disease ...

Applications in Plant Sciences, EarlyView.Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.

Deficiency of Carbonic Anhydrase II Results in a Urinary Concentrating Defect
Frontiers in Physiology, 2018 Carbonic anhydrase II (CAII) is expressed along the nephron where it interacts with a number of transport proteins augmenting their activity. Aquaporin-1 (AQP1) interacts with CAII to increase water flux through the water channel. Both CAII and aquaporin-

Advanced Physics Research, EarlyView.A physics‐grounded framework based on decoherence timescales (τ_dec vs τ_func), Markovian validity, and falsifiability criteria is applied across molecular systems to distinguish where quantum effects are necessary, marginal, or irrelevant. The analysis integrates quantum chemistry, biological quantum mechanisms, and quantum computing under a unified ...

Journal of Pharmacological Sciences, 2004 Targeted positioning of water channel aquaporin-2 (AQP2) strictly regulates body water homeostasis. Trafficking of AQP2 to the apical membrane is critical for the reabsorption of water in renal collecting ducts.

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease
Arthritis &Rheumatology, EarlyView.Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

NEPHROGENIC DIABETES INSIPIDUS: THE CRUCIAL ROLE OF AQUAPORINS
Bioscience InsightsNephrogenic diabetes insipidus (NDI) is a disorder marked by the kidney's inability to concentrate urine despite normal or elevated levels of vasopressin, often due to impairments in aquaporin-2 (AQP2) expression or function.
