Utilization of cannulated screw fixation of Jail and TiRobot-assisted percutaneous indirect reduction technique for AO/OTA type 41B2 tibial plateau fracture treatment.

Purpose: The present study was designed to investigate the precise procedure and effectiveness of percutaneous minimally invasive fixation assisted by TiRobot in managing AO/OTA type 41B2 tibial plateau fracture to provide an alternative solution for clinical application.

Methods: In total, 10 participants with AO/OTA type 41B2 tibial plateau fractures diagnosed by preoperative imaging examinations were enrolled in this study between May 2019 and May 2022. They were 5 males and 5 females, with an average age of 45.

Induced-Fit-Identification in a Rigid Metal-Organic Framework for ppm-Level CO Removal and Ultra-Pure CO Enrichment.

Removing CO from crude syngas via physical adsorption is an effective method to yield eligible syngas. However, the bottleneck in trapping ppm-level CO and improving CO purity at higher working temperatures are major challenges. Here we report a thermoresponsive metal-organic framework (1 a-apz), assembled by rigid Mg (dobdc) (1 a) and aminopyrazine (apz), which not only affords an ultra-high CO capacity (145.

Quasi-Orthogonal Configuration of Propylene within a Scalable Metal-Organic Framework Enables Its Purification from Quinary Propane Dehydrogenation Byproducts.

Propylene production via nonoxidative propane dehydrogenation (PDH) holds great promise in meeting growing global demand for propylene. Effective adsorptive purification of a low concentration of propylene from quinary PDH byproducts comprising methane (CH), ethylene (CH), ethane (CH), propylene (CH), and propane (CH) has been an unsolved academic bottleneck. Herein, we now report an ultramicroporous zinc metal-organic framework (Zn-MOF, termed as ) underlying a rigid one-dimensional channel, enabling trace CH capture and effective separation from quinary PDH byproducts.

One-Step Ethylene Purification by an Ethane-Screening Metal-Organic Framework.

Efficient purification of ethylene (CH) from ethane (CH) is a crucial but daunting task for the chemical industry given their similar physical natures and molecular dimensions. Reversed capture of CH from CH/CH dual-mixtures can be expected to directly yield high-purity CH through a one-step separation unit, but it remains a daunting challenge. Here, we skillfully target an unusual "electrostatic-driven linker microrotation" () in a Zr-MOF through coupling dual-ligands having electron-withdrawing/donating groups (e.

An improvement on the technique of transosseous tunnels for the fixation of lower pole patella fracture: Cerclage around the patella.

The technique of transosseous tunnels is widely used in lower pole patella fracture (LPP). Though the extensor mechanism can be restored, distal avulsion fragments are usually unstable. The subsequent fracture gap and nonunion impair the extensor mechanism in turn.

Artificial Intelligence to Diagnose Tibial Plateau Fractures: An Intelligent Assistant for Orthopedic Physicians.

Objective: To explore a new artificial intelligence (AI)-aided method to assist the clinical diagnosis of tibial plateau fractures (TPFs) and further measure its validity and feasibility.

Methods: A total of 542 X-rays of TPFs were collected as a reference database. An AI algorithm (RetinaNet) was trained to analyze and detect TPF on the X-rays.

Berberine prevents human nucleus pulposus cells from IL‑1β‑induced extracellular matrix degradation and apoptosis by inhibiting the NF‑κB pathway.

Intervertebral disc degeneration (IDD) is widely considered to be one of the main causes of lower back pain, which is a chronic progressive disease closely related to inflammation, nucleus pulposus (NP) cell apoptosis and extracellular matrix (ECM) degradation. Berberine (BBR) is an alkaloid compound with an anti‑inflammatory effect and has been reported to exert therapeutic action in several inflammatory diseases, including osteoarthritis. Therefore, it was hypothesized that BBR may have a therapeutic effect on IDD through inhibition of the inflammatory response.
