Purpose: This study aimed to investigate whether combining the analysis of different magnetic resonance imaging (MRI) signs enhances the diagnostic accuracy of lateral meniscus posterior root tears (LMPRTs) in patients with anterior cruciate ligament (ACL) injuries. We hypothesised that analysing the cleft, ghost and truncated triangle signs and lateral meniscus extrusion (LME) measurement together would improve the preoperative MRI-based diagnosis of LMPRTs.
Methods: This retrospective study used prospectively collected registry data from two academic centres, including patients undergoing primary or revision ACL reconstruction (ACLR) and LMPRT repair.
Polymer Ligands with Multi-Nitrogen Heterocyclic Carbenes for Enhanced Stability and Reactivity in Nanoparticle Surface Functionalization.

Nitrogen heterocyclic carbenes (NHCs) are emerging as effective substitutes for conventional thiol ligands in surface functionalization of nanoparticles (NPs), offering exceptional stability to NPs under harsh conditions. However, the highly reactive feature of NHCs limits their use in introducing chemically active groups onto the NP surface. Herein, we develop a general yet robust strategy for the efficient surface functionalization of NPs with copolymer ligands bearing various functional groups.

Increasing demand for adeno-associated virus (AAV) used in gene therapy highlights the need to enhance AAV production. When intracellular AAV2 and extracellular AAV9 were produced in HEK293T cells using the triple transfection method, apoptosis occurred during the AAV production. To mitigate apoptosis induced by AAV production, the pro-apoptotic BAX/BAK1 genes were knocked out in HEK293T cells.

The slope aspect is an important environmental factor, which can indirectly change the acceptable solar radiation of forests. However, the mechanism of how this aspect changes the underground ecosystem and thus affects the growth of aboveground trees is not clear. In this study, Pinus yunnanensis plantation was taken as the research object, and the effects of soil and microbial characteristics on tree growth under different slope aspects and soil depths were systematically analyzed.

Background: Fibrous dysplasia (FD) is the most common benign tumor of the ribs, with surgical resection being the preferred treatment modality for rib FD, leading to enhanced quality of life and favorable outcomes. The complexity of surgical intervention varies depending on the location of costal FD, presenting challenges for both open surgical and thoracoscopic approaches. In this study, we present a novel technique for three-port robotic-assisted costectomy utilizing a Gigli saw, detailing our initial findings and outcomes.
