Variations of the anterior communicating artery

, 2000
Study was performed in 30 human cadavers during autopsy. The anterior communicating artery was present in all investigated cases. In 30% of instances the artery was of diameter less than 1 mm (hypoplastic)

Regulating Cells Fate and Function to Facilitate Bone Regeneration via Designing Programmable Bio‐Interactive Materials

Advanced Science, EarlyView.
This article aims to elucidate the biological mechanisms of bone repair and the evolution of material design, highlighting key cellular and molecular processes. It further proposes strategies and prospects for programmable bio‐interactive materials, which enable precisely guided bone tissue regeneration by dynamically regulating cell behavior and the ...

Two variations of the anterior communicating artery: A clinical reminder

, 2004
Of the 30 cadavers we examined two unusual variations of the anterior communicating artery (ACoA) were observed. In the first case ACoA was duplicated with a fenestrated anterior cerebral artery (ACA).

Ruptured partially thrombosed anterior inferior cerebellar artery aneurysms : two case reports and review of literature [PDF]

, 2016
2016-11Aneurysms arising from the distal anterior inferior cerebellar artery (AICA) are very rare. When the parent artery is an AICA−posterior inferior cerebellar artery (PICA) variant, occlusion of the artery, even distal to the meatal loop, leads to a ...

Programmable Paracrine‐Mimetic Microneedle System for Temporal Regulation of Cardiac Repair

Advanced Science, EarlyView.
Temporal signaling is encoded into a programmable paracrine‐mimetic microneedle patch via tris(2,2'‐bipyridyl)dichlororuthenium(II) hexahydrate/sodium persulfate‐tuned hydrogel microparticles that deliver TGF‐β, IGF‐1, and VEGF over phase‐matched 7‐, 14‐, and 28‐day windows.

Giant anterior communicating artery aneurysm with intrasellar extension

, 2023
Introduction: Aneurysms extending into the sella are uncommon with only a few cases reported till date. Most of these arise from either the supraclinoidal or infraclinoidal segments of the internal carotid artery.

14‐3‐3γ Protects Against Postoperative Cognitive Dysfunction by Regulating Tau Thr205 Phosphorylation and Synaptic Integrity

Advanced Science, EarlyView.
Integrative multi‐cohort analyses identify 14‐3‐3γ as a biomarker and regulator of cognitive vulnerability. Experimental studies show that 14‐3‐3γ loss is associated with Tau Thr205 phosphorylation, synaptic dysfunction, and cognitive impairment, while genetic overexpression or pharmacological stabilization of 14‐3‐3γ confers protective effects in ...
