Anti-Hepatitis B Virus Activity of Esculetin from Microsorium fortunei In Vitro and In Vivo

Molecules, 2019
Coumarins are widely present in a variety of plants and have a variety of pharmacological activities. In this study, we isolated a coumarin compound from Microsorium fortunei (Moore) Ching; the compound was identified as esculetin by hydrogen and carbon ...

Metal nanostructure‐coupled label‐free localized surface plasmon resonance biosensors for rapid and sensitive disease diagnosis

BMEMat, EarlyView.
LSPR biosensing enables rapid, sensitive, and low‐sample‐volume detection of biomarkers, with broad applications in diagnosing cancer, infectious, and chronic diseases. Advances in nanostructure design, micro/nanofabrication, and microfluidic integration have expanded the potential of LSPR sensors in biomedical diagnostics.

Seroprevalence for Hepatitis E and Other Viral Hepatitides among Diverse Populations, Malawi

Emerging Infectious Diseases, 2015
Data on prevalence of hepatitis E virus (HEV) in Malawi is limited. We tested blood samples from HIV-uninfected and -infected populations of women and men enrolled in research studies in Malawi during 1989–2008 to determine the seroprevalence of HEV ...

Examination of the Polypeptides of Hepatitis B Surface Antigen

Journal of General Virology, 1976
When the polypeptides of hepatitis B surface antigen were examined by SDS-polyacrylamide gel electrophoresis under a variety of conditions, anomalous results were found to be due to (i) variable and at times incomplete dissociation of polypeptides after boiling with 1% SDS and reducing agent, (ii) reaggregation of solubilized material under certain ...

Characterization and immunogenicity of nanoparticle vaccines displaying embecovirus spike proteins

Biotechnology Progress, EarlyView.
Virus‐like particle vaccines displaying spike proteins from OC43, HKU1 A, and HKU1 B were evaluated in mice for their ability to elicit antibodies against the spike proteins from OC43, HKU1 A, HKU1 B, and HKU1 C. Abstract Endemic human coronaviruses OC43 and HKU1 cause widespread respiratory infections and can be associated with severe illness in ...

Hepatitis B Surface Antigen in Corneal Donors

American Journal of Ophthalmology, 1987
Using an enzyme immunoassay, we detected hepatitis B surface antigen in washings of ocular tissue from two of three corneal donors who had positive serum assays for hepatitis B surface antigen. Hepatitis B surface antigen was identified in emulsified corneal tissue from one of two donors from whom corneal tissue was available for study.
