Non-Invasive Monitoring of the Impact of Low-Level Viremia on Liver Fibrosis in Treated Chronic Hepatitis B Patients.

Background: Chronic hepatitis B (CHB) presents a global health challenge due to its potential to cause severe liver conditions such as hepatocellular carcinoma (HCC) and cirrhosis. Prior research has established a correlation between CHB infection with low-level viremia (LLV) and liver disease progression, such as increased HCC incidence. This study aims to investigate whether LLV during treatment with nucleos(t)ide analogs (NAs) contributes to the accelerated progression of liver fibrosis (LF).

Mechanisms and Advances of Epigenetic Regulation in Cardiovascular Disease.

Epigenetics refers to heritable changes in gene expression and function that impact nuclear processes associated with chromatin, all without altering DNA sequences. These epigenetic patterns, being heritable traits, are vital biological mechanisms that intricately regulate gene expression and heredity. The application of chemical labeling and single-cell resolution mapping strategies has significantly facilitated large-scale epigenetic modifications in nucleic acids over recent years.

The Emerging Role of Ferroptosis in Sepsis, Opportunity or Challenge?

Sepsis is a syndrome in multi-organ dysfunction triggered by a deleterious immunological reaction of the body to a condition caused by infection, surgery, or trauma. Currently, sepsis is thought to be primarily associated with abnormal immune responses resulting in organ microcirculatory disturbances, cellular mitochondrial dysfunction, and induced cell death, although the exact pathogenesis of sepsis is still inconclusive. In recent years, the role of abnormal metabolism of trace nutrients in the pathogenesis of sepsis has been investigated.
