Body Size and Habitat Association as Determinants for Water Balance, Temperature Relations, and Behavioral Performance in Leptodactylid Frogs

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The association between species' habitat preferences (e.g., aquatic, terrestrial, arboreal) and traits related to body temperature regulation and water balance has been relatively well studied in anurans. However, whether such associations hold for species occupying the same general habitat while differing in other relevant functional ...

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

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.

The distribution characteristics of aquaporin 4 antibody in patients with neuromyelitis optica and the relationship between aquaporin 4 antibody and oligoclonal bands

Chinese Journal of Contemporary Neurology and Neurosurgery, 2014
Objective To explore the distribution characteristics of aquaporin 4 (AQP4) antibody in serum and cerebrospinal fluid (CSF) of neuromyelitis optica (NMO) patients, and to analyze the relationship between AQP4 antibody and oligoclonal bands (OB) in CSF

Accelerated Motion‐Compensated Diffusion‐Weighted pCASL Using Subspace Low‐Rank Reconstruction for Quantification of BBB Water Exchange and Permeability

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an accelerated motion‐compensated diffusion‐weighted pseudo‐continuous arterial spin labeling (MCDW‐pCASL) method using a spatial subspace low‐rank reconstruction method for efficient quantification of blood–brain barrier (BBB) water exchange (kw) and permeability (PSw).

Distribution of aquaporin-4 water channel expression within rat kidney

, 1995
The aquaporins are a family of transmembrane proteins that function as molecular water channels. Recently, a mercurial-insensitive water channel [MIWC or aquaporin-4 (AQP4)] has been cloned, and its mRNA was found to be expressed strongly in kidney ...

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 ...

Update on the intriguing roles of AQP4 expression and redistribution in the progression and treatment of glioma

Annals of Medicine
Aquaporin 4 (AQP4) is abundant in the human brain and has an important role in brain homeostasis and diseases. AQP4 expression has been found to be associated with glioma malignancies.

Distinct serum and cerebrospinal fluid cytokine and chemokine profiles in autoantibody-associated demyelinating diseases

Multiple Sclerosis Journal - Experimental, Translational and Clinical, 2019
Background Demyelinating diseases of the central nervous system associated with autoantibodies against aquaporin-4 and myelin-oligodendrocyte-glycoprotein are mediated by different immunopathological mechanisms compared to multiple sclerosis.
