Microsurgical obliteration of craniocervical junction dural arteriovenous fistulas via a suboccipital median approach: a retrospective study.

Objective: The authors report on a broad range of microsurgical procedures in which the suboccipital median technique was used to treat craniocervical junction arteriovenous fistulas. Their aim was to evaluate the efficacy of the suboccipital posteromedian approach and to assess the associated clinical outcomes.

Methods: The authors extracted information on the fistula site, clinical manifestation, and structural characteristics of arterial and venous vessels by retrospectively evaluating cases from a neurointerventional database spanning 10 years.

Bridging immune-neurovascular crosstalk via the immunomodulatory microspheres for promoting neural repair.

The crosstalk between immune cells and the neurovascular unit plays a pivotal role in neural regeneration following central nervous system (CNS) injury. Maintaining brain immune homeostasis is crucial for restoring neurovascular function. In this study, an interactive bridge was developed via an immunomodulatory hydrogel microsphere to link the interaction network between microglia and the neurovascular unit, thereby precisely regulating immune-neurovascular crosstalk and achieving neural function recovery.

Application of polyamide 56 nanofiber membrane loaded with coffee grounds carbon dots in Fe detection.

One novel nanofiber membrane was fabricated which could detect Fe with the help of either fluorescence spectrometer or smartphone. Coffee grounds carbon dots (CCDs) were prepared by the solvent-thermal method, followed by the fabrication of CCDs/polyamide 56 (PA56) composite nanofiber membrane through electrospinning process. The 4 % CCDs/PA56 composite nanofiber membrane (FNM4) maintained good fluorescence performance (λ = 554 nm, λ = 470 nm) even after 5-runs quenching-recovery cycles.

A nomogram for predicting the risk of cerebral vasospasm after neurosurgical clipping in patients with aneurysmal subarachnoid hemorrhage.

Purpose: Cerebral vasospasm (CVS) is a common complication that occurs after neurosurgical clipping of intracranial aneurysms in patients with aSAH. This complication can lead to clinical deterioration and a poor prognosis. The aim of this study is to explore the risk factors for CVS in aSAH patients who have undergone neurosurgical clipping, develop a nomogram for CVS, and evaluate its performance.

The Atherogenic Index of Plasma Predicts Carotid in-Stent Restenosis: Development and Validation of a Nomogram.

Purpose: To explore the predictive value of atherogenic index of plasma(AIP) for carotid in-stent restenosis(ISR).

Methods: Patients who underwent carotid artery stenting (CAS) in hospital from January 2016 to January 2021 were retrospectively enrolled. They were randomly divided into training and validation sets.

Construction of a ratiometric phosgene probe by chromophore formation from auxochrome.

A new fluorescent probe for ratiometric detection of phosgene is reported. This probe was constructed with classic 1,8-naphthalimide and 2-(2-aminophenyl)benzimidazole by Ullmann coupling reaction. After exposure to phosgene, yellow fluorescence weakened while blue fluorescence enhanced significantly.
