Enhancement of adult liver regeneration in mice through the hepsin-mediated epidermal growth factor receptor signaling pathway.

Given the widespread use of partial hepatectomy for treating various liver pathologies, understanding the mechanisms of liver regeneration is vital for enhancing liver resection and transplantation therapies. Here, we demonstrate the critical role of the serine protease Hepsin in promoting hepatocyte hypertrophy and proliferation. Under steady-state conditions, liver-specific overexpression of Hepsin in adult wild-type mice triggers hepatocyte hypertrophy and proliferation, significantly increasing liver size.

Femtosecond laser-induced Au nanostructure-decorated with plasmonic nanomaterials for sensitive SERS-based detection of fentanyl.

Fentanyl and its analogs have emerged as the main factor behind the ongoing opioid abuse globally in recent years. However, the existing techniques for sensitive and accurate detection of fentanyl are often complex, laborious, expensive, and restricted to central healthcare facilities. We reported herein a plasmonic biochip fabricated by the femtosecond laser-induced nanostructures and plasmonic nanomaterials for sensitive SERS-based detection of fentanyl.

Addition of neutrophil-to-lymphocyte ratio to Pre-DAA FIB-4 does not increase prediction value for de novo liver complications in hepatitis C.

Background And Aims: Direct-acting antiviral agents (DAAs) achieve high sustained virologic response (SVR) in chronic hepatitis C patients; yet a proportion of patients still experience de novo liver complications after SVR. Identification of risk factors is clinically important. FIB-4 index is a useful noninvasive tool to assess fibrosis, while neutrophil-to-lymphocyte ratio (NLR) is a biomarker for systemic inflammation.

Design and Discovery of a Potent and Selective Inhibitor of Integrin αvβ1.

Selective inhibition of the RGD (Arg-Gly-Asp) integrin αvβ1 has been recently identified as an attractive therapeutic approach for the treatment of liver fibrosis given its function, target expression, and safety profile. Our identification of a non-RGD small molecule lead followed by focused, systematic changes to the core structure utilizing a crystal structure, modeling, and a tractable synthetic approach resulted in the identification of a potent small molecule exhibiting a remarkable affinity for αvβ1 relative to several other integrin isoforms measured. Azabenzimidazolone demonstrated antifibrotic efficacy in an rat liver fibrosis model and represents a tool compound capable of further exploring the biological consequences of selective αvβ1 inhibition.

Mac-2 binding protein glycosylation isomer at 5 years of antiviral therapy predict hepatocellular carcinoma and mortality beyond year 5 in chronic hepatitis B patients with cirrhosis.

Whether serum Mac-2 binding protein glycosylation isomer (M2BPGi) level at year 5 of treatment could predict hepatocellular carcinoma (HCC) development and mortality beyond year 5 of entecavir or tenofovir disoproxil fumarate (TDF) treatment in chronic hepatitis B (CHB) patients with cirrhosis remain unclear. This retrospective study investigated the role of M2BPGi level at year 5 of treatment in predicting HCC and mortality beyond year 5 in CHB patients with cirrhosis. This study analyzed 1385 cirrhotic patients receiving entecavir or TDF treatment.

Precision and Robust Models on Healthcare Institution Federated Learning for Predicting HCC on Portal Venous CT Images.
