Efficacy and safety of oral pulmonary vasodilators in pulmonary veno‐occlusive disease

Pulmonary Circulation, 2022
Pulmonary veno‐occlusive disease (PVOD) or pulmonary capillary hemangiomatosis (PCH) is a rare subtype of pulmonary hypertension with dismal prognosis.

Cellular changes at the glia-neuro-vascular interface in definite idiopathic normal pressure hydrocephalus

Frontiers in Cellular Neuroscience, 2022
Idiopathic normal pressure hydrocephalus (iNPH) is a subtype of dementia with overlap toward Alzheimer's disease. Both diseases show deposition of the toxic metabolites amyloid-β and tau in brain.

Retinal oxygen supply shaped the functional evolution of the vertebrate eye

eLife, 2019
The retina has a very high energy demand but lacks an internal blood supply in most vertebrates. Here we explore the hypothesis that oxygen diffusion limited the evolution of retinal morphology by reconstructing the evolution of retinal thickness and the

Modeling of water rising in systems of cylindrical capillaries of different radii

Advanced Engineering Research, 2016
The promotion of water in the systems of cylindrical capillaries is studied in detail. A mathematical model of the water movement in both symmetric and asymmetric capillaries connected to a vertical capillary is built.

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 ...

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)

Leukocyte margination in alveolar capillaries: Interrelationship with functional capillary geometry and microhemodynamics [PDF]

, 1999
The pulmonary capillary microvasculature harbors a large pool of intravascularly marginated leukocytes. In this study, we investigated the interrelationship of leukocyte margination with characteristics of functional capillary geometry and ...

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.
