Development of a multi-laboratory integrated predictive model for silicosis utilizing machine learning: a retrospective case-control study.

Department of Laboratory, West China School of Public Health and West China Fourth Hospital, Sichuan University, Chengdu, China.
Objective: Due to the high global prevalence of silicosis and the ongoing challenges in its diagnosis, this pilot study aims to screen biomarkers from routine blood parameters and develop a multi-biomarker model for its early detection.
Methods: A case-control study was conducted to screen biomarkers for the diagnosis of silicosis using LASSO regression, SVM and RF. A sample of 612 subjects (half cases and half controls) were randomly divided into training and test groups in a 2:1 ratio.

To explore the intergenerational cardiotoxicity of nanoplastics, maternal mice were exposed to 60 nm polystyrene nanoplastics (PS-NP) during pregnancy and lactation. The results showed that PS-NP can enter the hearts of offspring and induce myocardial fiber arrangement disorder, acidophilic degeneration of cardiomyocytes, and elevated creatine kinase isoenzymes (CK-MB) and lactate dehydrogenase (LDH) levels after maternal exposure to PS-NP at 100 mg/kg during pregnancy and lactation. Mechanistically, KEGG analysis of RNA sequencing showed the participation of hypoxia-inducible factor-1 (HIF-1) and ferroptosis in PS-NP-induced cardiotoxicity.

Background: Real-time and rapid detection of ingredients in food has important significance for food safety. However, traditional detection methods not only require bulky and costly instruments but also are often based on single-mode analysis, limiting their accuracy and applications in point-of-care testing. Herein, an integrated and miniaturized dual-mode device based on colorimetric and photoacoustic (PA) principles is developed, using Au@Ag nanoparticles (Au@AgNPs) as signal probe and ascorbic acid (AA) and ascorbate oxidase (AAO) as analytes.

An 83-year-old female patient presented with angina pectoris, hemoglobinuria and jaundice. Laboratory diagnostics proved difficult due to hemolysis in all blood tubes, following re-evaluation after warming the blood sample.With low haptoglobin, elevated lactate dehydrogenase and elevated indirect bilirubin, we made a suspected diagnosis of autoimmune hemolytic anemia with cold antibodies, which was confirmed through a positive Coombs test and detection of C3d-loaded erythrocytes.

Nicotinamide adenine dinucleotide is a crucial coenzyme in cellular metabolism and is implicated in various diseases. This work introduces an electrochemical bioanalytical method utilizing solution-phase formate dehydrogenase (CbFDH) for detecting its oxidized form (NAD) in human blood plasma samples. The detection mechanism involves the catalytic conversion of NAD to NADH, facilitated by CbFDH in the presence of formate.
