Excessive DNA Double‐Strand Breaks–Associated 3D Genome Reorganization Contributes to Neural Tube Defects with Folate Deficiency

open access: yesAdvanced Science, EarlyView.
Neural tube defects (NTDs) are among the most common congenital malformations. However, the underlying etiology and mechanism remain elusive. Here, the role of DNA double‐strand breaks (DSBs) in 3D genome organization within the NTDs with folate deficiency is reported.

Pigment Epithelium‐Derived Factor Deficiency Impairs Hippocampal Glutamate Homeostasis and Cognitive Function by Downregulating Astrocytic GLT‐1

open access: yesAdvanced Science, EarlyView.
The chronic glutamate‐induced excitotoxicity hypothesis has profoundly informed the therapeutic strategies employed in Alzheimer’s disease (AD). This study shows pigment epithelium‐derived factor (PEDF) regulates astrocytic glutamate transporter‐1 (GLT‐1)‐mediated glutamate homeostasis and cognition. Reduced PEDF correlates with lower Mini‐Mental State

Subventricular Zone‐on‐a‐Chip: A Model to Study Neurogenesis Disruption in Neonatal Intraventricular Hemorrhage

open access: yesAdvanced Science, EarlyView.
A human subventricular zone‐on‐a‐chip is developed to model intraventricular hemorrhage (IVH) in preterm infants. This platform enables the study of inflammation‐driven neurogenic disruption. Exposure to hemorrhagic cerebrospinal fluid and red blood cell lysate activated inflammatory pathways, with IL1B emerging as a key mediator.

Potentiating Cerebral Perfusion Normalizes Glymphatic Dynamics in Systemic Inflammation

open access: yesAdvanced Science, EarlyView.
LPS‐induced systemic inflammation increases glymphatic influx but delays cervical lymphatic drainage, accompanied by AQP4 depolarization and impaired glymphatic clearance. Enhancing cerebral blood flow via the inotropic agent levosimendan effectively restored AQP4 polarization, improving glymphatic flux and amyloid‐β clearance.

Integrated ‘Shield‐Spear’ Biological Patch for Fibrosis‐Free Bladder Reconstruction

open access: yesAdvanced Science, EarlyView.
Fibrosis‐free bladder reconstruction remains challenging. This study pioneers an integrated “shield‐spear” patch: The outer anionic hydrogel layer captures GATA6+ macrophages to suppress collagen overexpression, while the inner S100 aptamer‐engineered EVs target Schwann cells to downregulate the TGFβ/Smad pathway—inhibiting fibrosis with enhanced wound

Novel Approach to Difficult Spinal Reconstruction: Bilateral Simultaneous Rib and Iliac Crest Vascularized Bone Graft Spinoplastic Surgery

open access: yesPlastic and Reconstructive Surgery, Global Open
Summary:. Pseudoarthrosis is a severe complication of spinal fusion surgery with occurrence rates as high as 35%–40%. Current options of revision surgery to correct pseudoarthrosis frequently carry high failure rates and risk of developing junctional ...

Native chick laminin-4 containing the beta 2 chain (s-laminin) promotes motor axon growth. [PDF]

open access: yes, 1996
After denervation of muscle, motor axons reinnervate original synaptic sites. A recombinant fragment of the synapse specific laminin beta 2 chain (s-laminin) was reported to inhibit motor axon growth.
