Application of 3D‐Slicer combined with 3D printing technology in training neurosurgery resident physicians' imaging spatial cognition and clinical reasoning: A self‐controlled before‐ and after‐study

Anatomical Sciences Education, EarlyView.
Abstract Neurosurgical residency training requires advanced spatial cognition and 3D anatomical understanding, which traditional methods often fail to adequately develop. This study evaluated a novel educational model integrating 3D Slicer and 3D printing technology to enhance imaging spatial cognition and clinical reasoning among neurosurgery ...

Dissecting the angiogenic mechanism of pachychoroid polypoidal choroidal vasculopathy

iMeta, EarlyView.
A prognosis‐oriented classification system was established to distinguish Pachy PCV from Non‐pachy PCV using a large multicenter dataset. Comparative plasma multi‐omics profiling of Pachy PCV, Non‐pachy PCV, and normal controls revealed unique upregulation of the fluid shear stress and atherosclerosis (FSS‐AS) and HIF‐1 signaling pathways in Pachy PCV.
