Primary balloon angioplasty for chronic occlusion of intracranial internal carotid artery: A case report

Journal of Interventional Medicine, 2022
Chronic occlusion of large intracranial arteries is the main cause of ischemic stroke in China. Patients with symptomatic intracranial artery occlusion and hemodynamic impairment are at high risk of recurrent stroke. Chronic occlusion of the intracranial

Intraorbital aneurysm of the ophthalmic artery

BMJ Case Reports, 2019
Intraorbital ophthalmic artery (OA) aneurysms are rare. They can be asymptomatic or present with visual disturbances, exophthalmos and headaches. We present a case of a 57-year-old man who presented with reduced vision, diplopia and exophthalmos. A carotid artery angiogram identified a right OA aneurysm. Due to the low risk of rupture and the patient’s

S100A14 in Tumor‐Derived EVs Targets PIAS3 to Reprogram Astrocytes and Induce Immunosuppressive Microenvironment Promoting Brain Metastasis and Germacrone Reversal Effect

Advanced Science, EarlyView.
This study identifies S100A14 in tumor‐derived exosomes as a key driver of brain metastasis. S100A14 targets PIAS3 in astrocytes, activating STAT3 signaling and promoting immunosuppressive MDSCs recruitment via chemokine secretion. Germacrone, a natural compound, binds S100A14 to disrupt this axis, effectively inhibiting brain metastasis with low ...

GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

Advanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.
