Nanozymes, as superior alternatives to natural enzymes, frequently employ the inhibition effect in turn-off sensors for analyte detection. However, limited attention has been paid to the inhibition mechanisms between analytes and nanozymes, limiting advancements in nanozyme-based sensing. Benefiting from the synergistic effects between three-dimensional network structure of aerogel and ligand effect triggered electronic regulation, PtBi aerogel nanozymes (PtBi ANs) exhibit superior peroxidase-like activity (293.

Background: Minimally invasive surgeries are increasingly central to modern medicine, particularly in liver transplantation. These techniques, which offer reduced trauma, precise operations, minimal bleeding, and swift recovery, are, however, unevenly adopted across China. Only a limited number of centers routinely perform minimally invasive donor hepatectomies, indicating a significant imbalance in the development and application of these advanced procedures.

"No-donor" liver transplantation.

Hepatobiliary Pancreat Dis Int

February 2025

Liver transplantation is hindered by organ shortage. The potential way to relieve this issue is to expand the donor pool via extending the donor criteria and make full use of all available grafts. The concept of "no-donor" liver transplantation allows grafts to be recovered from other liver recipients.

Lithium-sulfur (Li-S) batteries display promise as redox-based batteries, where separators are an essential part of preventing short-circuiting of the positive and negative electrodes, while the shuttle effect is a critical issue of separators. Currently, commercial PP separators are weak in inhibiting the polysulfides shuttling, so modified separators are needed to inhibit it to improve the battery performance. This paper reports that CeVO/KB composites act as separator materials.

  • The study investigates how the expression and secretion of HBsAg from integrated HBV DNA affect the ability to achieve a functional cure for chronic hepatitis B.
  • It analyzes liver biopsy samples from 625 patients, including treatment-naive and functionally cured individuals, to compare HBsAg levels and explore the mechanisms behind HBsAg secretion differences in HBeAg-positive versus negative patients.
  • Results show that HBeAg-negative patients have lower serum HBsAg but similar intrahepatic levels, with impaired secretion linked to an increase in preS1 mRNA from integrated HBV DNA, disrupting the balance in transcriptional activity of related promoters.

Dysregulated glycerophospholipid (GP) metabolism in the brain is associated with the progression of neurodegenerative diseases including Alzheimer's disease (AD). Routine liquid chromatography-mass spectrometry (LC-MS)-based large-scale lipidomic methods often fail to elucidate subtle yet important structural features such as sn-position, hindering the precise interrogation of GP molecules. Leveraging high-resolution demultiplexing (HRdm) ion mobility spectrometry (IMS), we develop a four-dimensional (4D) lipidomic strategy to resolve GP sn-position isomers.

Fms-like tyrosine kinase 3 (FLT3) is a receptor tyrosine kinase (RTK) primarily expressed in hematopoietic stem cells and dendritic cells (DCs). While FLT3 plays a critical role in the proliferation, development and maintenance of DCs, thus influencing immune responses under both normal and pathological conditions, there also exists some evidence that FLT3DC may be involved with immune responses in liver transplantation (LT). In this study, results from single-cell sequencing data analysis revealed a clear relationship between FLT3DCs and Regulatory T cells (Tregs) in liver tissue of LT recipients.
