Differential down-regulation of aquaporin-2 in rat kidney zones by peripheral nociceptin/orphanin FQ receptor agonism and vasopressin type-2 receptor antagonism

, 2007
Udgivelsesdato: 2007-NovWe previously showed that aquaresis induced by the peripherally acting nociceptin/orphanin FQ receptor agonist ZP120 is associated with a decreased protein level of aquaporin-2 (AQP2) in whole-kidney homogenates.

Enhanced 3D Filter‐Exchange Imaging Using Multi‐Slab Acquisition

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Starting from the implementation of a single‐slice FEXI sequence, a 3D method was developed to accelerate a FEXI experiment and acquire a multi‐slice volume. Methods 3D multi‐slab FEXI divides the volume of interest into different slabs.

In Vivo Dynamic D2O‐MRI for Quantifying Apparent CSF Water Renewal Across Ventricular and Extraventricular Compartments

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The choroid plexus has long been regarded as the principal source of cerebrospinal fluid (CSF), yet this view remains unresolved. We developed a dynamic indirect D2O MRI approach to quantify regional apparent CSF water renewal in vivo in rats at 9.4 T.

Chronic high‐altitude exposure and intracerebral hemorrhage: A novel perspective from the vascular‐immune‐neuronal network

Neuroprotection, EarlyView.
Long‐term chronic high‐altitude hypobaric hypoxia increases susceptibility to ICH, particularly among migrant populations lacking EPAS1/SENP1 adaptive genetic variants relative to high‐altitude indigenous residents. Persistent hypoxia initiates blood–brain barrier (BBB) breakdown, aberrant glial and immune activation, and progressive neuronal injury ...

Bulbophyllum weddellii (Orchidaceae) demonstrates foliar water uptake plasticity along Brazilian campos rupestres

Nordic Journal of Botany, EarlyView.
Phenotypic plasticity can facilitate species survival in a variety of conditions that are not possible with a fixed phenotype. Foliar water uptake (FWU), defined as the absorption of water through leaf surfaces, is an important mechanism contributing to plant water balance and drought tolerance in many species.

Urine Aquaporin-2: A Promising Marker of Response to the Arginine Vasopressin Type-2 Antagonist, Tolvaptan in Patients with Congestive Heart Failure

, 2016
Aquaporin-2, a member of the aquaporin family, is an arginine vasopressin-regulated water channel expressed in the renal collecting duct, and a promising marker of the concentrating and diluting ability of the kidney.

Molecular Biomarkers in Meniere's Disease: A Scoping Review of Current Evidence

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Meniere's disease is a complex chronic inner ear condition that is characterized by vertigo, tinnitus, aural fullness, and progressive hearing loss. Currently, diagnostic strategies remain symptom‐driven, and treatments focus on management of discrete episodes rather than targeting underlying pathophysiology.
