[Revision of anterior cruciate ligament reconstruction: Interpretation of the consensus by the European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA)].

Revision of anterior cruciate ligament (ACL) reconstruction is more challenging than primary ACL reconstruction and often yields less favorable outcomes. The European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA) has established a consensus regarding preoperative diagnosis, assessment, and selection criteria for ACL revision surgery. This consensus addresses 18 key issues that are most pertinent to clinical practice, providing guiding recommendations aimed at improving the prognosis of ACL revisions.

Stability Study of Anticoagulant Hydrogel Coatings Toward Long-Term Cardiovascular Devices.

Implantable cardiovascular devices have revolutionized the treatment of cardiovascular diseases, yet their long-term functionality without causing thrombosis is a persistent challenge. Although the surface modification of anticoagulant coating has greatly improved the biocompatibility of the devices, its long-term stability in complex physiological environments still remains questionable. Herein, the stability of three anticoagulant hydrogel coatings, poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC), poly(sodium 2-acryloyl-2-methylpropanesulfonate) (PAMPS), and poly(4-styrenesulfonate sodium) (PSS), is studied.

Anti-Mold Activities of Cationic Oligomeric Surfactants.

Molds are persistent and harmful but receive far less research attention compared with pathogenic bacteria. With the increase in microbial resistance to single-chain surfactant antimicrobial agents, it is crucial to investigate how surfactant structures affect the antimicrobial activity of surfactants. Here, we have studied the antimold efficacy of a series of oligomeric cationic quaternary ammonium surfactants at varying oligomerization levels with or without dynamic covalent imine bonds.

Biomimetic Nanostructure Engineering of Ultralow Ir-Loading Electrocatalysts for Oxygen Reduction Reaction.

Promoting the rate of the oxygen reduction reaction (ORR) is critical for boosting the overall energy efficiency of the flexible zinc-air batteries (FZABs). Inspired by nature, we designed "branch-leaf" like hierarchical porous carbon nanofibers with ultralow loadings of Ir nanoparticles (NPs) derived from covalent-organic framework/metal-organic framework (COF/MOF) core-shell hybrids. The as-obtained Ir/FeZn-hierarchical porous carbon nanofibers (HPCNFs) showcase enhanced ORR performance, and the ultralow Ir loading reduces the cost while maintaining catalytic capacity.

New motivation for injury prevention in the face of dramatic demographic changes in China.

B7-H3 CAR-T cell therapy combined with irradiation is effective in targeting bulk and radiation-resistant chordoma cancer cells.

Background: Chordoma is a slow-growing, primary malignant bone tumor that arises from notochordal tissue in the midline of the axial skeleton. Surgical excision with negative margins is the mainstay of treatment, but high local recurrence rates are reported even with negative margins. High-dose radiation therapy (RT), such as with proton or carbon ions, has been used as an alternative to surgery, but late local failure remains a problem.

Stratification system with dual human endogenous retroviruses for predicting immunotherapy efficacy in metastatic clear-cell renal cell carcinoma.

Background: Endogenous retrovirus (ERV) elements are genomic footprints of ancestral retroviral infections within the human genome. While the dysregulation of ERV transcription has been linked to immune cell infiltration in various cancers, its relationship with immune checkpoint inhibitor (ICI) response in solid tumors, particularly metastatic clear-cell renal cell carcinoma (ccRCC), remains inadequately explored.

Methods: This study analyzed patients with metastatic ccRCC from two prospective clinical trials, encompassing 181 patients receiving nivolumab in the CheckMate trials (-009 to -010 and -025) and 48 patients treated with the ipilimumab-nivolumab combination in the BIONIKK trial.

Association of systemic inflammatory markers with white matter hyperintensities and microstructural injury: an analysis of UK Biobank data.

We sought to investigate the relationship between systemic inflammation markers and imaging markers of CVSD, namely white matter hyperintensity (WMH) and microstructural injury.

Methods: We conducted a study involving both cross-sectional and longitudinal data from the UK Biobank Cohort.

Endosymbionts as hidden players in tripartite pathosystem of interactions and potential candidates for sustainable viral disease management.

The convoluted relationships between plants, viruses, and arthropod vectors housing bacterial endosymbionts are pivotal in the spread of harmful plant viral diseases. Endosymbionts play key roles in: manipulating host responses, influencing insect resistance to pesticides, shaping insect evolution, and bolstering virus acquisition, retention, and transmission. This interplay presents an innovative approach for developing sustainable strategies to manage plant diseases.

Modulating the Coordination Environment of Atomically Dispersed Nickel for Efficient Electrocatalytic CO Reduction at Low Overpotentials and Industrial Current Densities.

Electrocatalytic CO-to-CO conversion with a high CO Faradaic efficiency (FE) at low overpotentials and industrial-level current densities is highly desirable but a huge challenge over non-noble metal catalysts. Herein, graphitic N-rich porous carbons supporting atomically dispersed nickel (NiN-O sites with an axial oxygen) were synthesized (denoted as O-Ni-N-GC) and applied as the cathode catalyst in a CORR flow cell. O-Ni-N-GC showed excellent selectivity with a FE over 92% at low overpotentials ranging from 17 to 60 mV, and over 99% at 80 mV.

Ultrathin 2D Cu-Porphyrin MOF Nanosheet Loaded FeO Nanoparticles As a Multifunctional Nanoplatform for Synergetic Chemodynamic and Photodynamic Therapy Independent of O.

In this study, we developed a multifunctional nanoplatform to address the limitations of strictly acidic pH for the Fenton reaction involving FeO and the low efficiency of mono treatments. The hybrid material, FeO@Cu-TCPP, was assembled through hydrophobic interactions of polyvinylpyrrolidone (PVP) coated on its surface. The efficiency of the Fenton reaction using FeO was significantly enhanced by the photo-Fenton process in the presence of Cu-TCPP.

We previously reported a new targeting site at the dimer interface of AR (dimer interface pocket) and identified a novel antagonist M17-B15 that failed in oral administration.

Impacting Dynamics of Droplets on Cylindrical Superhydrophobic Surfaces Decorated with a Convex Ridge.

This work investigates the dynamic behavior of droplets on superhydrophobic cylindrical surfaces with a convex ridge through experimental analysis, focusing on the effects of varying the diameter ratio ( = ) and the ridge width ratio (δ = ). Impact morphology diagrams are established to reveal the morphology transition of the droplet as a function of and δ. The splash threshold is obtained, and the energy loss during the collision process is analyzed by examining the recovery coefficient and the splitting angle, with the splitting threshold found to be dependent on δ.
