Antibodies to hepatitis E and A viruses among patients with non-alcoholic chronic liver disease in Taiwan

The prevalence of hepatitis E virus (HEV) and hepatitis A virus (HAV) infection in patients with non-alcoholic chronic liver disease (CLD) was assessed. Antibody levels to HEV (anti-HEV) and HAV (anti-HAV) were evaluated in 100 pairs of CLD patients and healthy controls. The prevalence of anti-HEV was higher in patients (10.0%) than in controls (0%; p = 0.0001). There was no difference in anti-HAV positivity between patients (95%) and controls (93%). The patient group with anti-HEV was older (p = 0.024) and had more smokers (p = 0.03), having a higher prevalence of antibodies to hepatitis C virus (p = 0.02). Patients with anti-HAV were older than patients without (p = 0.0001). The prevalence of anti-HAV in patients more than 30 years old was higher than younger patients (95.1% versus 73.6%, p = 0.011). HEV may superinfect on chronic liver disease in an area hyperendemic for hepatitis A and B.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
