Intra-articular adductor canal block has equivalent analgesic effect to traditional ultrasound-guided adductor canal block after total knee arthroplasty: a prospective randomized controlled trial.

Introduction: An adductor canal block (ACB) is widely accepted as a regional nerve block for pain management following total knee arthroplasty (TKA). However, no consensus exists concerning whether the analgesic effect is greater when joint surgeons perform intra-articular ACBs (IA-ACBs) or when anesthesiologists perform ultrasound-guided ACBs (UG-ACBs). We hypothesized that intra-articular ACBs (IA-ACBs) performed by joint surgeons and UG-ACBs performed by anesthesiologists based on peri-articular injections (PAI) would yield equivalent analgesic effects.

Electrophoretic deposition of Ag-Cu-CTS coatings on porous titanium with photothermal-responsive antibacterial effect.

Porous architecture of titanium implants offers significant advantages in promoting osseointegration and mitigating the "stress shielding" effect. However, challenges remain in enhancing vascularization and preventing infection, especially given the complexities of modifying the intricate surface structure of porous titanium (PT). This study introduces a novel surface modification technique of PT using anti-gravity perfusion electrophoretic deposition (EPD) technique to fabricate antibacterial coatings containing silver (Ag) and copper (Cu) co-doped mesoporous silica nanoparticles (Ag-Cu@MSN) and chitosan binder on the surface of PT.

Metabolic Nanoregulators Induce Ferroptosis and Change Metabolite Flow to Reverse Immunosuppressive Tumor Microenvironment.

Aberrant energy and substance metabolic pathways of tumor cells critically support tumor cell proliferation by hijacking the resources from nonmalignant cells, thereby establishing a metabolite flow favorable to tumor progression. This metabolic adaptation of tumor cells further modulates the immune landscape, ultimately creating a tumor microenvironment characterized by drug resistance and immunosuppression. The synergistic regulation of energy and substance metabolic pathways might be a good antitumor therapeutic paradigm.

Zwitterionic Polymer Binder Networks with Structural Locking and Ionic Regulation Functions for High Performance Silicon Anodes.

The silicon anode suffers from significant volume expansion, low electrical conductivity, and poor long-term cycling performance, which collectively limit its potential to replace graphite as the anode material for lithium-ion batteries. In this article, a PAA-p(HEA-SBMA) binder was prepared by an in situ thermal cross-linking method, which combines strong mechanical properties and excellent reaction kinetics. The synergy of covalent bonding, dynamic hydrogen bonding, and ionic interactions in the binder structure provides excellent mechanical strength, which effectively dissipates stresses and "locks" the entire structure.

The token undermining effect: When and why adding a small reward to a dated outcome makes it less preferred.

The mere token strategy, which adds a small reward (token) to an option to increase attractiveness, is widely used in the consumer field. However, we conducted six studies that seek to confirm the 'token undermining effect', where adding a small token to a sooner and smaller reward (SS) paired with a later and larger reward (LL) decreases the preference for the SS. The results showed that the effect persists across various choice sets, participant populations, reward amounts, delays, outcome properties and regardless of whether the scenarios are incentivized.
