miR-18a-5p/PXR/SREBP2 Was Involved in MAFLD Associated With Methyl Tert-Butyl Ether Among Petrol Station Workers.

Background: Metabolic associated fatty liver disease (MAFLD), previously defined as non-alcoholic fatty liver disease (NAFLD), has been shown to be closely related to many environmental pollutants. Lately, we found methyl tert-butyl ether (MTBE), a new environmental pollutant, could increase NAFLD risk in American adults, which still needs more population epidemiological studies to verify, and its pathogenic mechanism is not yet clear.

Methods: We conducted a cross-sectional study among petrol station workers, diagnosed their MAFLD according to internationally recognised diagnostic criteria, assessed the potential association of MTBE exposure with MAFLD risk, and explored the miR-18a-5p/PXR/SREBP2 pathway as possible pathogenic mechanisms in male Wistar rats and HepaRG cells treated with MTBE.

Investigating the key principles in two-step heterogeneous transfer learning for early laryngeal cancer identification.

Data scarcity in medical images makes transfer learning a common approach in computer-aided diagnosis. Some disease classification tasks can rely on large homogeneous public datasets to train the transferred model, while others cannot, i.e.

DNA-compatible one-pot synthesis of multi-substituted dihydrofuran pyridinium ylide-mediated cyclization.

Synthesis of chemically diverse heterocyclic scaffolds in DNA-encoded libraries is highly demanded. We herein reported a convenient one-pot multi-component on-DNA synthetic strategy to afford multi-substituted 2,3-dihydrofuran scaffolds pyridinium ylide-mediated cyclization. This reaction exhibited modest to excellent conversions for a broad range of DNA-conjugated aldehydes, β-ketonitriles and pyridinium salts under mild reaction conditions.

Improvement of the accuracy of breeding value prediction for egg production traits in Muscovy duck using low-coverage whole-genome sequence data.

Low-coverage whole genome sequencing (lcWGS) is an effective low-cost genotyping technology when combined with genotype imputation approaches. It facilitates cost-effective genomic selection (GS) programs in agricultural animal populations. GS based on lcWGS data has been successfully applied to livestock such as pigs and donkeys.

Design and Synthesis of Hederagenin Derivatives for the Treatment of Sepsis by Targeting TAK1 and Regulating the TAK1-NF-κB/MAPK Signaling.

Sepsis is a systemic inflammatory response caused by infection and is a leading cause of death worldwide. We designed and synthesized a series of hederagenin analogues with anti-inflammatory activity. The most effective compound, , reduced the release of TNF-α and IL-6 in RAW264.
