Transmantle pressure under the influence of free breathing: non-invasive quantification of the aqueduct pressure gradient in healthy adults.
Fluids Barriers CNS
January 2025
Medical Image Processing Department, CHU Amiens-Picardie University Hospital, Amiens, France.
Background: The pressure gradient between the ventricles and the subarachnoid space (transmantle pressure) is crucial for understanding CSF circulation and the pathogenesis of certain neurodegenerative diseases. This pressure can be approximated by the pressure difference across the aqueduct (ΔP). Currently, no dedicated platform exists for quantifying ΔP, and no research has been conducted on the impact of breathing on ΔP.

Brain Imaging Behav
January 2025
Department of Radiology, the First Affiliated Hospital of Chongqing Medical University, Chongqing, 400016, China.
Background: Studies on the impact of white matter hyperintensity (WMH) on function outcome have primarily concentrated on WMH volume, overlooking the potential significance of WMH location. This study aimed to investigate the relationship between WMH location and outcome in patients with their first-ever acute ischemic stroke (AIS).
Methods: Patients who underwent their first AIS between September 2021 and September 2022 were recruited.
Hirudin promotes cerebral angiogenesis and exerts neuroprotective effects in MCAO/R rats by activating the Wnt/β-catenin pathway.

Department of Gerontology, The Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University, Luzhou, 646000, China. Electronic address:
Objective: Hirudin has shown potential in promoting angiogenesis and providing neuroprotection in ischemic stroke; however, its therapeutic role in promoting cerebrovascular angiogenesis remains unclear. In this study, we aimed to investigate whether hirudin exerts neuroprotective effects by promoting angiogenesis through the regulation of the Wnt/β-catenin signaling pathway.
Methods: An in vitro model of glucose and oxygen deprivation/reperfusion (OGD/R) was established using rat brain microvascular endothelial cells (BMECs).
Escape of Kdm6a from X Chromosome Is Detrimental to Ischemic Brains via IRF5 Signaling.

The role of chromatin biology and epigenetics in disease progression is gaining increasing recognition. Genes that escape X chromosome inactivation (XCI) can impact neuroinflammation through epigenetic mechanisms. Our previous study has suggested that the X escapee genes Kdm6a and Kdm5c are involved in microglial activation after stroke in aged mice.

December 2024
Sunnybrook Health Sciences Centre, Toronto, ON, Canada.
Background: White matter hyperintensities (WMH) are commonly observed on MRI in Alzheimer's disease (AD), but the molecular pathways underlying their relationships with the ATN biomarkers remain unclear. The aim of this study was to identify genetic variants that may modify the relationship between WMH and the ATN biomarkers.
Method: This genome-wide interaction study (GWIS) included individuals with AD, MCI, and normal cognition from ADNI (n = 1012).
