Forward‐Biased Perovskite Photodiodes for In‐Sensor Optical Change Sensing

Advanced Functional Materials, EarlyView.
A forward‐biased perovskite photodiode is introduced as an in‐sensor analog preprocessing unit that uses current balancing between photocurrent and injection current to generate optical changes relative to programmable optical reference levels. The device directly converts reference‐relative optical changes into bipolar current signals, enabling sensor‐

Mechanical Evaluation Of Locking Compression Plate [PDF]

, 2018
Locking Compression Plate, LCP has been widely used in the femoral shaft fracture fixation. The clinical cases show that the failure of locking compression plate is possible before the adequate healing of the fracture.

Modern anatomical locking plates are associated with increased postoperative wound complications and unplanned surgical revisions compared to standard tubular plates in the management of unstable ankle fractures: a comparative cohort study in 595 patients

Patient Safety in Surgery
Background The clinical benefit of locking plates in distal fibula fractures has not yet been proven. In addition, the risk of wound complications appears to be higher than with conventional tubular plates.

3D‐Printed Gradient Shape‐Memory Strain Sensors With Rewritable Gauge Factors

Advanced Functional Materials, EarlyView.
A 3D‐printed shape‐memory strain sensor combines thermomechanical programming with gradient architectural design. Preset strain rewrites the gauge factor (GF), while the gradient geometry amplifies the response through strain redistribution. Reprogrammable sensitivity enables the same sensor to detect weak pulse signals and monitor large‐amplitude ...

Biomechanical evaluation of acromion and scapular spine fracture repair techniques systematic review

JSES Reviews, Reports, and Techniques
Background: The incidence of reverse total shoulder arthroplasty (rTSA) is rising. Acromion and scapular spine fractures (ASFs) are a known complication following rTSA with an incidence rate of around 5%.

A biomechanical study of headless compression screws versus a locking plate in radial head fracture fixation

, 2019
Hypothesis: Fixation of a 3-part radial head fracture with cannulated compression screws will show equivalent stiffness to a locking plate under axial load. Debate exists regarding the management of Mason type III fractures, with many believing that open

Targeting CD300a Signaling With a Phosphatidylserine‐Presenting Hydrogel Rescues Macrophage Dysfunction and Accelerates Diabetic Wound Healing

Advanced Healthcare Materials, EarlyView.
Schematic illustration of the proposed mechanism: PEG/RGD‐PSLs mimic apoptotic cells to engage PS receptors (notably CD300a), transducing an inhibitory signal that suppresses the MyD88/NF‐κB pathway, leading to global anti‐inflammatory and pro‐reparative effects.
