Longitudinal changes in peritoneal solute transport rate and the impact of lower glucose degradation product glucose dialysates

Therapeutic Apheresis and Dialysis, Volume 29, Issue 3, Page 471-478, June 2025.
Abstract Introduction Peritoneal solute transfer rates (PSTR) are reported to increase with time. Changes in PSTR were reviewed in long‐term peritoneal dialysis (PD) patients to determine whether lower glucose degradation products (low GDP) dialysates prevented an increase in PSTR. Methods PSTR was determined with a 4‐h peritoneal equilibrium test with

Lead induces increased water permeability in astrocytes expressing aquaporin 4

, 2005
The water channel aquaporin 4 (AQP4) is abundantly expressed in astrocytes. There is now compelling evidence that AQP4 may contribute to an unfavorable course in brain edema.

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Aquaporin-4 expression is not elevated in mild hydrocephalus

, 2011
Aquaporin-4 (aqp-4) is a member of water channel family proteins primarily expressed in the central nervous system. Physiologically it is the main channel providing water transport into the nervous system water compartments and across the blood-brain ...

Wasteosomes accumulate in periventricular white matter hyperintensities and exhibit complex relationships with mixed pathology, sclerotic index, and perivascular space

Brain Pathology, EarlyView.
In a mixed diagnostic cohort of pathologically diagnosed Alzheimer's disease, cerebrovascular disease, mixed pathology, and control tissue, we connected the histopathological wasteosome profile in periventricular (PV) brain sections to 7T FLAIR‐MRI confirmed PV white matter hyperintensities (WMHs), vascular stenosis and perivascular space size ...

Genetic Insights Into AVP Deficiency: Identification of a Novel AVP Variant and Compilation of a Curated Catalogue of Pathogenic Variants

Clinical Genetics, EarlyView.
We identified a novel pathogenic AVP variant in two Danish families with autosomal dominant inheritance of symptoms of AVP deficiency. In addition, we compiled a catalogue of additionally 109 AVP variants that cause AVP deficiency and demonstrated the advantage of combining expert‐assisted curation, literature search, and online repositories to ensure ...

Structural features of aquaporin 4 supporting the formation of arrays and junctions in biomembranes

, 2012
A limited class of aquaporins has been described to form regular arrays and junctions in membranes. The biological significance of these structures, however, remains uncertain.

A review of skin microbiome and new challenges to cosmetic microbiome‐friendly formulations

International Journal of Cosmetic Science, EarlyView.
Microbiome‐friendly concepts offer new perspectives for a healthy relationship between cosmetic use and the skin microbiome, especially the interaction of non‐biotic cosmetic ingredients with the skin, requiring further studies to clarify the dynamics between the skin microbiome and different classes of cosmetic ingredients.
