Feasibility study on pre-treatment quality assurance using the EPID system of the uRT-linac 506c.

Purpose: With the rapid development of computer technology, techniques with high modulation capabilities, such as Intensity Modulated Radiation Therapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT), have been widely applied in radiotherapy. As a result, it has become essential to perform Pre-treatment Quality Assurance (PQA) for each treatment plan to prevent radiation accidents. We aim to validate the novel uRT-linac 506c's EPID system as an alternative method for PQA by comparing the performance with IMatriXX.

Acteoside suppresses hepatocellular carcinoma progression via modulation of macrophage migration inhibitory factor and mitogen-activated protein kinase proteins.

This study investigated acteoside's (ACT) inhibition of hepatocellular carcinoma (HCC) progression via macrophage migration inhibitory factor (MIF) and MAPK signaling; immunohistochemistry and in situ hybridization assessed MIF/MAPK expression in HCC, cirrhotic, and normal tissues. The effects of ACT on HepG2 and Huh-7 cells were evaluated via CCK-8 assays, wound healing assays, and Transwell assays. Cell lines with MIF knockdown or overexpression were established to explore MIF's role.

The Extension Arm Design Method Based on a Two-Bar Tension Stretchable Mechanism.

The deployable and foldable structure is a unique structural system that provides convenience in terms of transportation and expansion. Although the current deployable mast can transition between closed and extended structures, it lacks stability during movement and does not have the ability to recover on its own after contracting. Hence, improving the stability of deployable mechanisms while enabling them to self-restore has become an essential area for development.

Prevalence of infection in Chinese military personnel: A cross-sectional, multicenter-based study.

However, the prevalence of infection and its regional distribution in the military population remain unclear, which hinders effective prevention and treatment strategies.

lncRNA-NEF regulates hepatic stellate cells proliferation, cell cycle, apoptosis and ECM synthesis through the ERK1/2/c-Fos axis.

In this study, we investigated the role of lncRNA-NEF in modulating hepatic stellate cell (HSC) activation, a key process in liver fibrosis. Using the GSE78160 dataset, we identified lncRNA-NEF as downregulated in liver cirrhosis patients. Gene Ontology and KEGG analyses implicated it in transcriptional regulation and cell cycle control.

Direct inhibition of microglial activation by a μ receptor selective agonist alleviates inflammatory-induced pain hypersensitivity.

Opioids are widely used in the treatment of moderate and severe pain. Nociceptive stimulation has been reported to potentially promote microglial activation and neuroinflammation, which also causes chronic pain sensitization. The aim of this study was to demonstrate whether the novel μ receptor agonist MEL-0614 could inhibit activated microglia directly and the associated signaling pathway.

Induction of Broadly Cross-Reactive Antibody Responses to SARS-CoV-2 Variants by S1 Nanoparticle Vaccines.

Despite the rapid deployment of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines, the emergence of SARS-CoV-2 variants and reports of their immune evasion characteristics have led to an urgent need for novel vaccines that confer potent cross-protective immunity.
