Neurovascular Uncoupling Is Linked to Microcirculatory Dysfunction in Regions Outside the Ischemic Core Following Ischemic Stroke

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Normal brain function depends on the ability of the vasculature to increase blood flow to regions with high metabolic demands. Impaired neurovascular coupling, such as the local hyperemic response to neuronal activity, may contribute to poor ...

An unusual presentation of Goodpasture syndrome

Saudi Journal of Anaesthesia, 2023
Goodpasture disease is an anti–glomerular basement membrane (anti-GBM) disease that manifests as progressive glomerulopathy and alveolar hemorrhage. Our case was a 68-year-old female who presented with decompensated liver disease (DCLD) with no prior ...

White matter capillaries in vascular and neurodegenerative dementias

Acta Neuropathologica Communications, 2019
Previous studies suggest white matter (WM) integrity is vulnerable to chronic hypoperfusion during brain ageing. We assessed ~ 0.7 million capillary profiles in the frontal lobe WM across several dementias comprising Alzheimer’s disease, dementia with ...

Adaptive motility enables neutrophils to rapidly navigate confined capillaries. [PDF]

Sci Immunol
As the first responders of the immune system, neutrophils rapidly and abundantly reach inflamed tissues through blood capillaries. The diameter of capillaries can be as narrow as two microns, imposing considerable deformations on neutrophils.

Structural Microangiopathies in Skeletal Muscle Related to Systemic Vascular Pathologies in Humans

Frontiers in Physiology, 2020
It is unclear how microangiopathic changes in skeletal muscle vary among systemic vascular pathologies. We therefore analyzed the capillary fine structure in skeletal muscle from patients with arterial hypertension (HYPT), diabetes mellitus type 2 (T2DM)

Bottom-up synthesis of chiral covalent organic frameworks and their bound capillaries for chiral separation

Nature Communications, 2016
Covalent organic frameworks (COFs) are a novel class of porous materials, and offer great potential for various applications. However, the applications of COFs in chiral separation and chiral catalysis are largely underexplored due to the very limited ...

Curcumin reduces blood-nerve barrier abnormalities and cytotoxicity to endothelial cells and pericytes induced by cisplatin

Folia Morphologica, 2023
BACKGROUND: Cisplatin is a platinum-based antineoplastic agent used to treat cancers of solid organs. Neuropathy is one of its major side effects, necessitating dose reduction or cessation.

VEGF signaling regulates the fate of obstructed capillaries in mouse cortex

eLife, 2018
Cortical capillaries are prone to obstruction, which over time, could have a major impact on brain angioarchitecture and function. The mechanisms that govern the removal of these obstructions and what long-term fate awaits obstructed capillaries, remains

Hybrid integrated platform of PDMS microfluidics and silica capillary for effective CE and ESI-MS coupling [PDF]

, 2009
We present an effective hybrid integration of PDMS microfluidic devices and fused silica capillaries. These hybrid microfluidic integrated PDMS and silica capillary (iPSC) modules exhibit a novel architecture and method for leakage free CE sample ...
