Stroke penumbra defined by an MRI-based oxygen challenge technique: 2. Validation based on the consequences of reperfusion [PDF]

, 2011
Magnetic resonance imaging (MRI) with oxygen challenge (T2* OC) uses oxygen as a metabolic biotracer to define penumbral tissue based on CMRO2 and oxygen extraction fraction. Penumbra displays a greater T2* signal change during OC than surrounding tissue.

Actuated Hydrogel Platforms To Study Brain Cell Behavior

Advanced Healthcare Materials, EarlyView.
The complex and dynamic viscoelastic properties of the brain underpin neural plasticity and overall function. Actuating hydrogel platforms support mechanistic research to elucidate how brain cells respond to dynamic microenvironments. This study reviews the mechanobiology of the brain and its impact on brain function in health and disease and describes

Function of BID - a molecule of the bcl-2 family - in ischemic cell death in the brain [PDF]

, 2002
Mitochondrial mechanisms, particularly the release of cytochrome c, play a role in the death of nerve and glial cells in cerebral ischemia. We have currently investigated whether BID, a proapoptotic molecule of the bcl-2 family and promoter of the ...

Mesenteric Ischemia [PDF]

Seminars in Interventional Radiology, 2009
Mesenteric ischemia is classified as either acute or chronic. The former is a life-threatening emergency in which a sudden reduction in intestinal blood flow may ultimately result in bowel infarction. The most common causes are arterial embolism, arterial thrombosis, nonocclusive mesenteric ischemia, and mesenteric venous thrombosis.

CircAars‐Engineered ADSCs Facilitate Maxillofacial Bone Defects Repair Via Synergistic Capability of Osteogenic Differentiation, Macrophage Polarization and Angiogenesis

Advanced Healthcare Materials, EarlyView.
Schematic representation of circAars‐engineered‐ADSCs incorporated into GelMA scaffolds for craniomaxillofacial bone regeneration. CircAars‐engineered ADSCs embedded in GelMA scaffolds enhance the repair of critical‐sized bone defects by binding miR‐128‐3p in the cytoplasm, thereby inhibiting its activity.

The Long Noncoding RNA MALAT1 Induces Tolerogenic Dendritic Cells and Regulatory T Cells via miR155/Dendritic Cell-Specific Intercellular Adhesion Molecule-3 Grabbing Nonintegrin/IL10 Axis

Frontiers in Immunology, 2018
By shaping T cell immunity, tolerogenic dendritic cells (tDCs) play critical roles in the induction of immune tolerance after transplantation. However, the role of long noncoding RNAs (lncRNAs) in the function and immune tolerance of dendritic cells (DCs)

Analysis of a Mathematical Model of Ischemic Cutaneous wounds [PDF]

arXiv, 2009
Chronic wounds represent a major public health problem affecting 6.5 million people in the United States. Ischemia represents a serious complicating factor in wound healing. In this paper we analyze a recently developed mathematical model of ischemic dermal wounds.

Vulnerability of white matter to ischemia varies during development [PDF]

, 2011
Stroke is the one of the leading causes of mortality and morbidity in developed countries. The central role of injury to white matter in the pathophysiology of stroke has been recognised over the recent years.

Myocarcial ischemia.

Japanese Circulation Journal, 1985
As one of the cause of acute myocardial ischemia, coronary vasospasm has attracted attention increasingly in clinical cardiology. We developed animal model of coronary vasospasm associated with transient myocardial ischemia by administration of histamine or serotonin in atherosclerotic miniature swine.
