Abstract

The relevance of the GB virus C/hepatitis G virus (GBV-C/HGV) in blood banking results from its high prevalence in blood donors and the fact that it is present at a very high percentage (18%) in polytransfused and hemophiliac patients. Since there is no assay available for serological testing, we developed a sensitive PCR utilizing newly designed NS3 primers to investigate the prevalence in blood donors in Hessia. Testing 1,143 accepted blood donors with alaninaminotransferase (ALT) concentrations < 45 U/l we found 15 (1.3%) positive for GBV-C/HGV RNA. From 507 donors settling in urban Frankfurt areas, 10 (2.0%) were positive. Of those donors settling in rural hessian areas only 5/635 (0.8%) tested positive. By testing 100 excluded donors with ALT values > 45 U/l, 3% turned out to be positive. In 4 out of 9 recipients of GBV-C/HGV-positive blood products we detected the donor viral RNA as proved by sequencing and phylogenetic analysis. The virus was transmitted to 3 recipients by erythrocytes and to 1 recipient by platelets. Testing family members of the GBV-C/HGV-positive blood donors we could not detect any intrafamilial transmission.

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.
