Diversity of HBV genotypes and their association with precore/basal core mutations among HBsAg-positive patients in Ibadan, Nigeria.

Hepatitis B virus (HBV) is the most implicated cause of severe liver disease and hepatocellular carcinoma worldwide. Studies have shown that the basal core protein (BCP) and precore protein (PC) of HBV play a significant role in HBV-related carcinogenesis. There is a paucity of data on the type and effect of BCP and PC mutations in Nigeria.

Molecular detection and genotyping of HBV from HBsAg positive patients in a tertiary hospital in Nigeria.

Background: Nigeria remains one of the countries with a high hepatitis B virus (HBV) burden in Africa. Reports have indicated the presence of mixed HBV genotypes in Nigeria; however, there is still paucity of data regarding mixed genotype infections particularly in the Southern part of the country.

Objective: Our aim is to determine the HBV genotype distribution among HBsAg-positive gastroenterology patients at the University College Hospital Ibadan, Nigeria.

Mandibular Denture Base Deformation with Locator and Ball Attachments of Implant-Retained Overdentures.

Purpose: The aim of this in vitro study was to evaluate and compare mandibular denture base deformation between ball and Locator attachments of implant-retained overdentures.

Materials And Methods: An experimental acrylic model covered with resilient silicone mucosal simulation was constructed. Two laboratory implants were placed in the canine areas of the model.
