Nanostructured drug delivery systems for posterior segment eye diseases: Strategies to defy ocular barriers

open access: yesBMEMat, EarlyView.
Efficient drug delivery to the posterior segment of the eye has long been a challenging issue due to the complex ocular barriers. The review focuses on the promise held by nanoplatforms for barrier penetration and the key mechanisms involved, also highlighting their advantages in achieving efficient drug delivery and superior treatment of PSEDs ...

Non‐invasive and efficient diabetic retinal mitochondrial repair nanoplatform based on engineered endothelial mitochondrial‐derived vesicles with dynamic integrated stress response modulation

open access: yesInterdisciplinary Medicine, EarlyView.
Under hyperglycemic conditions, mitochondrial dysfunction in retinal endothelial cells triggers excessive reactive oxygen species/reactive nitrogen species production, barrier protein degradation, and endothelial barrier breakdown in diabetic retinopathy.

Pre‐operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno‐arterial extracorporeal membrane oxygenation or cardiac surgery

open access: yesJournal of Medical Radiation Sciences, EarlyView.
A pre‐cannulation survey of the circle of Willis (CoW) using transcranial Doppler (TCD) ultrasound was implemented to assess cerebral collateral circulation in children undergoing VA ECMO or cardiac surgery with cervical cannulation. The technique, in use since 2019, employs high‐end ultrasound platforms to assess brain morphology, haemorrhage and ...

Early choroidal structure and choroidal vascularity index change after carotid stenting

open access: yesPhotodiagnosis and Photodynamic Therapy, 2022
We aimed to evaluate changes in subfoveal choroidal thickness (SFCT) and choroidal vascularity index (CVI) in the first postoperative day and month in patients with severe internal carotid artery (ICA) stenosis after ICA stenting.The patients who diagnosed with severe ICA stenosis and was performed ICA stenting were included in the study. Patients with

CRPPA exon 6–9 deletion as a founder mutation in Chinese patients with dystroglycanopathy

open access: yesPediatric Investigation, EarlyView.
Analysis of sixteen Chinese dystroglycanopathy patients reveals a founder mutation (CRPPA exon 6–9 deletion) in 25% of cases and expands the phenotypic spectrum from severe muscle‐eye‐brain disease to limb‐girdle muscular dystrophy. ABSTRACT Importance Dystroglycanopathies (DGPs) are a group of muscular dystrophies with abnormal glycosylation of ...

Linking cardiological parameters and choroidal changes in patients with precapillary pulmonary hypertension: a cross-sectional study

open access: yesScientific Reports
Diagnosing precapillary pulmonary hypertension (PPH) is challenging, and prognosis remains poor. This study aims to explore the pathogenesis of choroidal changes in these patients and assess whether choroidal parameters could serve as noninvasive ...
