Tie2‐Dependent Mechanisms Influence Leptomeningeal Collateral Dynamics and Reperfusion Following Stroke

Advanced Science, EarlyView.
This work demonstrates that endothelial EphA4 limits Tie2 activation and curbs leptomeningeal collateral expansion after ischemic stroke. Pharmacological activation of Tie2 by an Ang‐1 mimetic or genetic loss of EphA4 stimulates collateral vessel growth, improves cerebral perfusion, and enhances neurological recovery.

Severe Edema and Venous Congestion Following Sphenoorbital Meningioma Resection in a Meningiomatosis Case: Importance of Predicting Venous Disturbances

Journal of Neurological Surgery Reports, 2015
To achieve local disease control, radical removal is the best option for sphenoorbital meningiomas. Preservation of the venous system is crucial during the resection of skull base meningiomas.

Magnetic resonance investigation into the mechanisms involved in the development of high-altitude cerebral edema [PDF]

, 2017
Rapid ascent to high altitude commonly results in acute mountain sickness, and on occasion potentially fatal high-altitude cerebral edema. The exact pathophysiological mechanisms behind these syndromes remain to be determined.

Iron Overload Mediates the Differential Cell Fate of Astrocytes from Neurons and Its Regulatory Mechanisms in Ischemic Stroke

Advanced Science, EarlyView.
Upon ischemia/reperfusion‐induced iron overload condition, neurons and astrocytes exhibit similar oxidative stress changes but opposite alterations in endogenous antioxidant defense mechanisms, leading to divergent ferroptotic outcomes. The iron deposition and neuronal loss are increased within the perilesional cortex of stroke patients ...

Salvage resection of advanced mediastinal tumors [PDF]

, 2019
The surgical treatment of locally advanced mediastinal tumors invading the great vessels and other nearby structures still represent a tricky question, principally due to the technical complexity of the resective phase, the contingent need to carry out

CARD9 Conveys Pancreatic Islet Sympathetic Nervous β2 Signals to Reshape Macrophage Creatine Metabolism in Type 1 Diabetes

Advanced Science, EarlyView.
This study identifies CARD9 as a key mediator linking sympathetic β2‐adrenergic receptor signaling to macrophage creatine metabolism, inflammatory polarization, and neuronal integrity. Loss of β2‐AR‐PKA‐CREB1‐CARD9 signaling in macrophages reduces creatine uptake, promotes pro‐inflammatory macrophage activation, and drives sympathetic axon ferroptosis.

Neutrophil Extracellular Trap Reprograms Cancer Metabolism to Form a Metastatic Niche Promoting Non‐Small Cell Lung Cancer Brain Metastasis

Advanced Science, EarlyView.
This study mainly combines spatial/single‐cell transcriptomics and metabolomics to reveal LOX+ Malig‐5 as NSCLC brain metastasis‐initiating cells, forming a niche with NET‐releasing neutrophils via the NET‐KRT10 axis. The metastatic niche is involved with metabolic reprogramming, with palmitic acid serving as a key metabolite.
