Highly Stretchable, Self‐Healable, and Conductive Gelatin Methacryloyl Hydrogel for Long‐Lasting Wearable Tactile Sensors

open access: yesAdvanced Science, EarlyView.
Gelatin methacryloyl hydrogel, which possesses high stretchability, tensile strength, toughness, and autonomous self‐healing capability at room temperature, is developed through the introduction of interpenetrating networks, hierarchical hydrogen bonds (weak and strong H‐bonds), and borate ester bonds.

Antagonist conditioning contractions impair agonist functioning [PDF]

open access: yes, 2010
This study assessed the effect of antagonist conditioning contractions (ACC) on the subsequent force and electromyography of an agonist. Twelve subjects performed isokinetic elbow flexion on a dynamometer in 4 test conditions including a baseline ...

Splicing Shift of RAC1 Accelerates Tumorigenesis and Defines a Potent Therapeutic Target in Lung Cancer

open access: yesAdvanced Science, EarlyView.
Dysregulated RNA splicing is an underappreciated molecular feature of cancer. By integrating murine and cellular models with patient specimens of lung adenocarcinoma, this study demonstrates that RAC1B, rather than RAC1A isoform, promotes tumorigenesis and presents a potent therapeutic target for lung cancer. Mechanistically, RAC1B preferentially binds

Wide Linearity Range and Rapid‐Response Tactile Sensor Inspired by Parallel Structures

open access: yesAdvanced Science, EarlyView.
Inspired by parallel structures, a composite tactile sensor design is proposed using parallel elastomer integration, developing two novel sensors. This strategy optimizes the force‐electric response and viscoelastic hysteresis of the conductive composite, achieving a balanced enhancement of linear sensing range and fast response.

Clavicular tunnel widening in chronic acromioclavicular joint instabilities after primary versus revision arthroscopically‐assisted acromio‐ and coracoclavicular stabilization

open access: yesJournal of Experimental Orthopaedics
Purpose To evaluate joint reduction (loss of reduction [LOR]; dynamic posterior translation [DPT]) and clavicular tunnel widening (cTW) in patients treated with arthroscopically‐assisted acromioclavicular joint (ACJ) stabilization after previously failed
