Quantification of Hepatitis B Virus DNA: Validation of a qPCR Approach to detect Pregnant Women at High Risk to Transmit the Virus in Mali.

Introduction: Mother-to-child transmission (MTCT) of hepatitis B virus (HBV) is one of the main causes of chronic hepatitis B in endemic regions such as West Africa. Its prevention constitutes an essential element to eliminate HBV. Without intervention, rates of vertical transmission of HBV vary depending on the level of viral replication.

Colorectal Cancer: The Contribution of CXCL12 and Its Receptors CXCR4 and CXCR7.

Colorectal cancer is one of the most common cancers, and diagnosis at late metastatic stages is the main cause of death related to this cancer. This progression to metastasis is complex and involves different molecules such as the chemokine CXCL12 and its two receptors CXCR4 and CXCR7. The high expression of receptors in CRC is often associated with a poor prognosis and aggressiveness of the tumor.
