Abstract

Two variants for APOL1; the gastrointestinal (G1) variant (S342G and 1384M substitutions) and the G2 variant (N388 and Y389 deletions) have been previously described to be associated with renal disease. The prevalence of APOL1 variants in Saudi Arabia is unknown. We aimed to determine the prevalence of APOL1 variants in a cohort of patients with renal disease in Saudi Arabia. Patients with renal disease followed up at King Abdulaziz University Hospital were approached consecutively at the out patient clinic, and unaffected controls were approached at the blood donation area. Clinical and laboratory data were collected from electronic medical records. Laboratory variables in controls were obtained on enrollment. This is a cross-sectional, cohort study. One hundred and one patients with a mean age of 54.5 (±19) years, and 119 unaffected controls with a mean age of 31.9 (±7.89) years, were enrolled. Seventy-four patients (68.5%) had hypertension and 62 (57.4%) had diabetes. The mean estimated glomerular filtration rate was 22.47 (± 27.6) mL/min. Two patients were heterozygous for G1 allele. Among the control group, two were heterozygous for G1 allele, and three were heterozygous for G2. All five controls had no evidence of renal d...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.
