Additional Dose of Intravenous Dexamethasone Can Replace Patient-Controlled Analgesia in Pain Control after Total Knee Arthroplasty while Reducing Opioid Complications.

Purpose The purpose of this study was to evaluate whether IV dexamethasone, within the current multimodal pain management protocol, (1) could maintain postoperative pain at a comparable level without IV PCA, (2) could reduce opioids-related side effects, and (3) whether an additional dose of dexamethasone on POD 2 would offer further pain-relieving effect without increasing the risk of complications. Methods A total of 178 patients (182 knees) who underwent total knee arthroplasty (TKA) for osteoarthritis were included in the study. The patients were divided into Dexa 2 & PCA and Dexa 3 & NoPCA group.

Therapy-induced senescent cancer cells contribute to cancer progression by promoting ribophorin 1-dependent PD-L1 upregulation.

Conventional chemotherapy- and radiotherapy-induced cancer senescence, which is characterized by poor proliferation, drug resistance, and senescence-associated secretory phenotype, has gained attention as contributing to cancer relapse and the development of an immunosuppressive tumor microenvironment. However, the association between cancer senescence and anti-tumor immunity is not fully understood. Here, we demonstrate that senescent cancer cells increase the level of PD-L1 by promoting its transcription and glycosylation.

12″ Wafer-Scale Mass-Manufactured Metal-Insulator-Metal Reflective Metaholograms by Nanotransfer Printing.

The unique characteristics of metasurfaces to precisely control the amplitude, phase, and polarization of light within a thin, flat footprint make them a promising replacement for bulky optical components. However, fabrication methods of conventional metasurfaces have suffered from low throughput and high costs, limiting scalability and practical application. To address these challenges, an advanced fabrication technique is developed by combining deep-ultraviolet argon fluoride photolithography with wafer-scale nanotransfer printing to facilitate the scalable fabrication of metal-insulator-metal structures.

Endonuclease G promotes hepatic mitochondrial respiration by selectively increasing mitochondrial tRNA production.

Mitochondrial endonuclease G (EndoG) contributes to chromosomal degradation when it is released from mitochondria during apoptosis. It is presumed to also have a mitochondrial function because EndoG deficiency causes mitochondrial dysfunction. However, the mechanism by which EndoG regulates mitochondrial function is not known.

Effects of maximum dose on local control after stereotactic body radiotherapy for oligometastatic tumors of colorectal cancer.

This study aimed to identify radiotherapy dosimetric parameters related to local failure (LF)-free survival (LFFS) in patients with lung and liver oligometastases from colorectal cancer treated with stereotactic body radiotherapy (SBRT). We analyzed 75 oligometastatic lesions in 55 patients treated with SBRT between January 2014 and December 2021. There was no constraint or intentional increase in maximum dose.
