Abstract

Tataouine (South Tunisia) has been subject to several viral hepatitis epidemics during these last years. Prospective study has been conducted to define the prevalence of HVB infection. It has examined 511 cases, the age of whom was between 1 month and 70 years, reported in groups through the OMS recommendations, taking into account the number of inhabitants in each area. The global prevalence was 6.2% for HBs Ag and 18.5% for HBs antibody. These results were not different from the frequencies observed within the Tunisian population in general. The analysis of this study according to these groups, shows that in three areas (Ras El Oued, Bir 30, Dhibet) 60 to 80% of cases have at least one of HVB marquers, whereas the prevalence in other areas (Rogba) was very weak. The geographic repartition of HVB infection corresponds approximatively to areas that have been the most infected by the last hepatitis epidemics. A second study has completed and confirmed the results of the first one, taking into consideration a more important number of cases from areas of strong and weak endemicity. 596 sera have been examined in Rogba which counts 2000 inhabitants and is a weak endemicity area. 528 sera have been examined in the three areas of str...Continue Reading

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.
