Assessing the relationship between wrist synovitis and anxiety: a study using clinical statistics and Mendelian randomization analysis.

Background: Wrist synovitis often leads to persistent pain, swelling, and limited mobility, causing significant functional impairment and psychological distress, including anxiety. Although arthroscopic synovectomy can alleviate physical symptoms, whether it also improves anxiety and the causal relationship between synovitis and anxiety remains unclear.

Methods: A prospective study was conducted on 44 patients diagnosed with wrist synovitis who underwent arthroscopic synovectomy.

18F-5-fluoro-aminosuberic acid PET/CT imaging of oxidative-stress features during the formation of DEN-induced rat hepatocellular carcinoma.

The role of oxidative stress metabolism during hepatocellular carcinoma (HCC) formation potentially allows for positron emission tomography (PET) imaging of oxidative stress activity for early and precise HCC detection. However, there is currently limited data available on oxidative-stress-related PET imaging for longitudinal monitoring of the pathophysiological changes during HCC formation. This work aimed to explore PET-based longitudinal monitoring of oxidative stress metabolism and determine the sensitivity of [18F]-5-fluoroaminosuberic acid ([18F]FASu) for assessing pathophysiological processes in diethylnitrosamine (DEN) induced rat HCC.

Self-augmented catabolism mediated by Se/Fe co-doped bioceramics boosts ROS storm for highly efficient antitumor therapy of bone scaffolds.

The overexpression of glutathione (GSH) within the tumor microenvironment has long been considered as the major obstacle for reactive oxygen species (ROS)-based antitumor therapies. To address this challenge, a selenite (SeO) and ferric ion co-doped hydroxyapatite (SF-HAP) nanohybrid was synthesized, which is then introduced into poly-L-lactic acid (PLLA) to prepare porous scaffold by selective laser sintering to continuously release Fe and SeO ions. Of great significance is the released SeO catabolize GSH to generate superoxide anion (O) rather than directly eliminating GSH, thereby reversing the obstacle posed by its overexpression and achieving a "waste-to-treasure" transformation.

Loss-of-function SLC25A20 variant causes carnitine-acylcarnitine translocase deficiency by reducing SLC25A20 protein stability.

Background/aim: Autosomal-recessive carnitine-acylcarnitine translocase deficiency (CACTD) is a rare disorder of long-chain fatty acid oxidation caused by variants in the SLC25A20 gene, leading to energy deficiency and the toxic accumulation of long-chain acylcarnitines. Under fasting conditions, most newborns with severe CACTD experience sudden cardiac arrest and hypotonia, often leading to premature death due to rapid disease progression. The genetic factors and pathogenic mechanisms in CACTD are essential for its diagnosis, treatment, and prevention.

A tripartite transcriptional module regulates protoderm specification during embryogenesis in Arabidopsis.

Protoderm formation is a crucial step in early embryo patterning in plants, separating the precursors of the epidermis and the inner tissues. Although key regulators such as ARABIDOPSIS THALIANA MERISTEM LAYER1 (ATML1) and PROTODERMAL FACTOR2 (PDF2) have been identified in the model plant Arabidopsis thaliana, the genetic pathways controlling protoderm specification remain largely unexplored. Here, we combined genetic, cytological, and molecular approaches to investigate the regulatory mechanisms of protoderm specification in Arabidopsis thaliana.
