Calciphylaxis as A Rare Cause of A Chronic Wound in An 83-Year-Old Woman

Geriatrics, 2019
Chronic wounds are common in elderly patients, and the majority of them are caused by vascular diseases, such as peripheral arterial occlusive disease (PAD) or chronic venous insufficiency.

Hyperbaric oxygenation effects determination in the therapy of chronic occlusive lower extremities arteries disease by the use of perfusion scintigraphy [PDF]

Vojnosanitetski Pregled, 2010
Background/Aim. Hyperbaric oxygenation (HBO) is a medical treatment of a patient with 100% oxygen inspiration under the pressure higher than atmospheric in a special unit designed to let the whole patient's body rest in a chamber.

The GRK2/AP‐1 Signaling Axis Mediates Vascular Endothelial Dysfunction and Atherosclerosis Induced by Oscillatory Low Shear Stress

Advanced Science, EarlyView.
This study highlights GRK2 is a central mediator in OSS‐induced endothelial dysfunction. OSS activates GPCRs in endothelial cells, leading to GRK2 phosphorylation and the activation of AP‐1. AP‐1 induces inflammation, while also promoting NR4A1 expression and anchoring LKB1 in the nucleus, which suppresses AMPK activity. This cascade causes endothelial

Large Artery Occlusive Disease

, 2016
Extracranial and intracranial large artery atherosclerosis is often identified as a potential etiologic cause for ischemic stroke and transient ischemic attack (TIA). Given the high prevalence of large artery atherosclerosis in the general population, optimally treating each patient to minimize future stroke risk is paramount.

Single‐Cell Transcriptome Analysis Reveals That Hmga2 Regulates Neuroinflammation and Retinal Function by Modulating Müller Cell Autophagy Through PI3K/AKT Signaling Following MCAO‐Induced Retinal Ischemia

Advanced Science, EarlyView.
Employing snRNA‐seq post‐MCAO‐induced retinal ischemia (RI), this study revealed a novel Hmga2‐high Müller cell subpopulation. Hmga2 knockout alleviated neuroinflammation and RI symptoms, potentially by binding PI3K and regulating Müller cell autophagy.

DNase I‐Mediated Chemotactic Nanoparticles for NETs Targeting and Microenvironment Remodeling Treatment of Acute Ischemic Stroke

Advanced Science, EarlyView.
The neutrophil extracellular traps (NETs) play an important role in reperfusion injury in ischemic stroke. Here, considering the unique vascular localization of NETs, a DNase I‐mediated NETs‐targeting nanoparticle is developed to integrate the catalytic and chemotactic functions of DNase I and achieve the synergistic regulation of the internal and ...

Neutrophil Mobilization Triggers Microglial Functional Change to Exacerbate Cerebral Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
These study underscores the pivotal role of neutrophil‐derived myeloid‐related protein 14 (MRP14) in the pathophysiology of acute ischemic stroke (AIS). MRP14 not only disrupts mitochondrial function, thereby inhibiting microglial phagocytosis of neutrophils, but also activates microglial pyroptosis, exacerbating neuroinflammation following AIS ...

Pathophysiological mechanism, clinical classification and treatment strategy of acute progressive large vessel occlusive stroke

Chinese Journal of Contemporary Neurology and Neurosurgery, 2020
Acute progressive large vessel occlusive stroke (APLVO) is a special kind of acute ischemic stroke with large vessel occlusion (AIS⁃LVO). Adequate medical history inquiry, detailed imaging analysis and appropriate individualized treatment can lead to ...

Regulation of Neuroinflammation by Microglial DUBA‐IRAK1‐IKKβ Signaling Loop

Advanced Science, EarlyView.
The protein levels of deubiquitinating enzyme A (DUBA) are rapidly upregulated in microglia after activation of Toll‐like receptor 4 (TLR4). In turn, DUBA potentiates TLR4‐induced proinflammatory signal transduction in microglia by stabilizing interleukin‐1 receptor activated kinase 1 (IRAK1) through K48 deubiquitination.
