Posterior Ankle Arthroscopic Reduction With Internal Fixation

Arthroscopy Techniques, 2016
Current surgical techniques in ankle fracture management now include arthroscopic-assisted reduction and internal fixation. The need for minimally invasive fracture reduction techniques, which preserve soft tissue envelops and assists in overall anatomic

Segond's fracture: a biomechanical cadaveric study using navigation [PDF]

, 2017
Background Segond’s fracture is a well-recognised radiological sign of an anterior cruciate ligament (ACL) tear. While previous studies evaluated the role of the anterolateral ligament (ALL) and complex injuries on rotational stability of the knee ...

Gigacycle fatigue properties of additively manufactured Hastelloy X

Science and Technology of Advanced Materials: Methods
Gigacycle fatigue tests were conducted on additively manufactured (AM) Hastelloy X. Individual AM samples manufactured in the Z and X directions were tested at room temperature, and the results were compared with those for conventionally produced ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Managing periprosthetic tibia fractures: International perspectives

OTA International: The Open Access Journal of Orthopaedic Trauma, 2023
Summary: Knee arthroplasty, both total knee and unicompartmental, has had a significant impact on millions of patients globally. Although satisfaction is usually high, complications such as periprosthetic fracture are increasingly common. Distal femur periprosthetic fractures are relatively well researched and understood in comparison with ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

FEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

Oxidation-induced changes in mechanical properties of silicon nitride ceramics [PDF]

, 1999
The effect of oxidation on the room-temperature mechanical properties of four different silicon nitride ceramics is investigated. The strength and the elastic modulus of the whole material and the hardness, the fracture toughness and the elastic ...
