The Complex Role of HBeAg and Its Precursors in the Pathway to Hepatocellular Carcinoma

Viruses, 2023
Hepatitis B virus (HBV) is one of the seven known human oncogenic viruses and has adapted to coexist with a single host for prolonged periods, requiring continuous manipulation of immunity and cell fate decisions.

Imaging Techniques: Essential Tools for the Study of SARS-CoV-2 Infection

Frontiers in Cellular and Infection Microbiology, 2022
The world has seen the emergence of a new virus in 2019, SARS-CoV-2, causing the COVID-19 pandemic and millions of deaths worldwide. Microscopy can be much more informative than conventional detection methods such as RT-PCR.

In vitro expression of precore proteins of hepatitis B virus subgenotype A1 is affected by HBcAg, and can affect HBsAg secretion

Scientific Reports, 2021
HBeAg, a non-particulate protein of hepatitis B virus (HBV), is translated from the precore/core region as a precursor, which is post-translationally modified.

In Vitro Systems for Studying Different Genotypes/Sub-Genotypes of Hepatitis B Virus: Strengths and Limitations

Viruses, 2020
Hepatitis B virus (HBV) infects the liver resulting in end stage liver disease, cirrhosis, and hepatocellular carcinoma. Despite an effective vaccine, HBV poses a serious health problem globally, accounting for 257 million chronic carriers.

Knowledge, attitudes and practices of undergraduate health sciences students on hepatitis B vaccination at a South African university highlight the need for improvement of policies, implementation and co-ordination

South African Medical Journal, 2023
Background. Hepatitis B virus (HBV) infection causes nearly 300 million chronic infections globally. Healthcare workers face up to four times the risk of HBV infection through occupational exposure to contaminated blood and bodily fluids.

Genomic diversity of vaccinia virus strain Cantagalo isolated in southeastern Brazil during the early years of the outbreak, 1999-2006 [PDF]

Memorias do Instituto Oswaldo Cruz, 2021
Outbreaks of a vesiculopustular disease in dairy cattle and milkers have been frequently reported in Brazil since 1999 when the vaccinia virus strain Cantagalo was first isolated in the State of Rio de Janeiro. However, the genomic diversity of the viral

Characterisation of the Viral Community Associated with the Alfalfa Weevil (Hypera postica) and Its Host Plant, Alfalfa (Medicago sativa)

Viruses, 2021
Advances in viral metagenomics have paved the way of virus discovery by making the exploration of viruses in any ecosystem possible. Applied to agroecosystems, such an approach opens new possibilities to explore how viruses circulate between insects and ...

Molecular characterization and genotyping of hepatitis C virus from Sudanese end-stage renal disease patients on haemodialysis

BMC Infectious Diseases, 2022
Background Hepatitis C virus (HCV) is a global public health problem, with ~ 11 million people in Africa infected. There is incomplete information on HCV in Sudan, particularly in haemodialysis patients, who have a higher prevalence compared to the ...
