Abstract

Liver biopsies from 52 patients with chronic hepatitis B were investigated for the presence and distribution of HBcAg and the results were compared with the status of hepatitis B virus deoxyribonucleic acid (HBV-DNA). The patients consisted of 37 men and 15 women, aged 16-55 years (mean = 34 years). Serum alanine aminotransferase (ALT) was elevated in 50 patients (range: 18-969 U/L; mean = 290 U/L). Serological testing showed HBsAg in all, HBeAg in 45 (87%), and HBV-DNA in 28 (54%). Liver biopsies demonstrated HBcAg in 35 (67%) patients. HBcAg was not only present in 31 of 45 (69%) patients who were seropositive for HBeAg, but also in four of seven (57%) with antibody to HBeAg (anti-HBe). In 28 of 35 (80%) patients with HBcAg in the liver, serum HBV-DNA was detected. However, no serum HBV-DNA was detected in 17 patients who had no detectable HBcAg in the liver. The distribution of HBcAg in the liver was rather cytoplasmic and nuclear than nuclear alone. Among 33 patients with cytoplasmic HBcAg in the liver, 15 (45%) had an evidence of acute exacerbation of hepatitis with marked ALT elevation (range: 168-894 U/L; mean = 385 U/L) and nine patients showed severe chronic active hepatitis and confluent necrosis, histologically.

COVID-19

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

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.

Evolution of Pluripotency

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.

Microbicide

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.
