Abstract

A significant reduction in the prevalence of both intestinal and urinary schistosomiasis has occurred in all emirates (districts) in all 12 foci of the infection distributed in five regions of Saudi Arabia. Infection with Schistosoma mansoni has dropped in foci of the infection in the Central Region (Riyadh and Hail) and in all foci within the western provinces. Reduction has also occurred in the prevalence of S. haematobium in foci of Gizan, the Red Sea coastal areas and parts of Madinah. The disease no longer exists around Riyadh. The overall prevalence in all 12 foci of infection in Saudi Arabia dropped gradually from 11% in 1983 to 1.9% in 1987. At present the infection rates among expatriates are much higher than among Saudis in most foci. The number of emirates which had rates of 10% or more has dropped from 46 in 1983, to nil in 1987, and the number with rates of 5-10% from 25 in 1983 to one in 1987. The overall prevalence is presently between 1 and less than 5% in 73 emirates and less than 1% in 41 emirates. Significant reduction was observed in most villages in each district. Higher infection rates may still be present in a few areas within one or two emirates not surveyed in the last 2-3 years. The potential danger of...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.
