Clinical Decision‐Making in Peptic Esophageal Stenosis: To PEG or Not to PEG?

open access: yesClinical Case Reports
Esophageal strictures can cause dysphagia and malnutrition requiring enteral feeding. We report a 78‐year‐old woman with therapy‐refractory distal esophageal stenosis initially considered benign.

Nuclear Pore Mechanotransduction in Oncology: A Structural Axis of Vulnerability for Targeted Intervention

open access: yesAdvanced Materials, EarlyView.
Cancer‐associated NPC remodeling creates a high‐flux, low‐stringency nuclear state that supports malignant adaptation but increases mechanical fragility. Targeting the FG‐barrier or NPC scaffold may drive mechanostat failure, envelope rupture, DNA damage, and loss of nuclear integrity.

Polar Wurtzite NbAlN: A Transition‐Metal Nitride Alloy for Polarization‐Engineered GaN Heterostructures

open access: yesAdvanced Materials, EarlyView.
A novel polar wurtzite alloy, NbAlN, is demonstrated as a transition‐metal‐containing polar barrier for GaN heterostructures. Nb atoms form coherent nanoscale enrichment within the wurtzite lattice without disrupting metal polarity. This study demonstrates that transition metals can be integrated into polar nitrides to enable polarization‐related ...

Dental Microwear Texture Analysis on Radular Teeth

open access: yesAdvanced Materials Interfaces, EarlyView.
3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.

Balloon dilatation of ureteric strictures

open access: yes, 2000
Aims: Evaluation of dilatation as a minimally invasive technique for the treatment of ureteric strictures. Material and Methods: We evaluated this technique in 16 patients with ureteric and secondary pelviureteric junction strictures from June 1998.

Programmable Pneumatic Actuator System for a Bioinspired Artificial Colon

open access: yesAdvanced Materials Technologies, EarlyView.
A modular soft robotic colon simulator driven by programmable pneumatic actuation is developed to mimic physiological and pathological‐like motility patterns of the large intestine. Finite element–guided design and distributed control enable anatomically realistic deformation for peristalsis, segmentation, and mass movements, supporting capsule ...

CT Evaluation of Long-Term Changes in Common Bile Duct Diameter after Cholecystectomy

open access: yesJournal of the Korean Society of Radiology
Purpose The present study aimed to investigate the frequency and extent of compensatory common bile duct (CBD) dilatation after cholecystectomy, assess the time between cholecystectomy and CBD dilatation, and identify potentially useful CT findings ...

A Self‐Healing Permanent Magnet Putty for Soft Robot Skins With Force Sensing and Functional Recovery

open access: yesAdvanced Robotics Research, EarlyView.
Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...
