Abstract:
Hepatitis B core antibody (anti-HBc) targets viral core protein and is produced in patients with hepatitis B virus (HBV) infection, and seroconversion occurs in the early stage of infection and often lasts for a lifetime. Qualitative detection of anti-HBc has been used in clinical practice for many years, while the clinical significance of its quantitative level remains unclear. A novel anti-HBc immunoassay based on double-antigen sandwich ELISA has been developed in recent years and lays a foundation for illustrating the change in the quantitative level of anti-HBc (qAnti-HBc) in HBV infection and its clinical significance. Several recent studies have revealed that qAnti-HBc is associated with the degree of hepatitis activity and response to pharmacotherapy and may become an important basis for selecting antiviral drugs, optimizing therapeutic regimen, and predicting treatment outcome.

Critical Region, Critical Values and Significance Level
In hypothesis testing, a sample statistic is converted to a test statistic using z, t, or chi-square distribution. A critical region is an area under the curve in probability distributions demarcated by the critical value. When the test statistic falls in this region, it suggests that the null hypothesis must be rejected. As this region contains all those values of the...

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
