NDFIP2 Suppresses Colorectal Cancer Metastasis Through DDX3X‐Dependent R‐Loop Remodeling and GNG13 Transcriptional Activation

Advanced Science, EarlyView.
NDFIP2 recruits NEDD4 to promote K48‐linked ubiquitination and proteasomal degradation of DDX3X, leading to R‐loop accumulation and CTCF‐dependent suppression of GNG13 transcription. Consequently, PI3K/AKT signaling, EMT, stemness, and colorectal cancer metastasis are inhibited.

The Bony Density of the Pedicle Plays a More Significant Role in the Screw Anchorage Ability Than Other Regions of the Screw Trajectory

Orthopaedic Surgery
Objective Osteoporosis is a crucial risk factor for screw loosening. Our studies indicate that the bone mineral density (BMD) in the screw trajectory is a better predictor of screw loosening than the BMD of the lumbar spine or the screw insertion ...

C1-C3 lateral mass fusion for type IIa and type III Hangman′s fracture

Journal of Craniovertebral Junction and Spine, 2012
Hangman′s fractures, also known as traumatic spondylolisthesis of axis, can be managed either conservatively with immobilization or by surgery. Surgery is usually indicated in cases with instability or failure of conservative treatment.

Six‐DoF Strawberry Harvesting Pose Selection and Adaptive Obstacle Clearing in Occluded Environments

Advanced Intelligent Systems, EarlyView.
An occlusion‐aware 6‐DoF harvesting strategy integrates γ‐angle pose selection, ripeness‐weighted risk evaluation, and adaptive obstacle clearing. The approach enables collision‐free grasping orientation selection and improves strawberry harvesting reliability under complex occlusion, achieving higher success rates and reduced fruit damage. In complex,

Healing Following Endoscopic Reconstruction of the Anterior Skull Base in Patients With Sinonasal Malignancies

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Healing dynamics after anterior skull base (ASB) reconstruction following transnasal endoscopic surgery (TES) for sinonasal malignancies remain poorly characterized. This study aimed to describe the postoperative healing process, quantify time to healing, identify factors influencing healing, and assess radiologic evolution over ...
