Abstract

Few studies have dealt with assaying aluminium levels in different tissues of uremic patients; so far a comparison has never been made between its accumulation in the various tissues of uremic patients and controls. Aluminium levels were determined in the following biological samples: 1) 111 serum samples from hemodialysis patients and 55 serum samples from normal subjects; 2) 47 urine samples from the same dialysis patients and 45 from the controls; autopsy tissue specimens (blood, bile, brain, rib, cartilage, cranium, lung, spleen, kidney, aorta, vena cava, liver, muscle) from 12 deceased dialysis patients undergoing post-mortem diagnosis and 10 autopsy cases in which death was not associated with uremia. In living subjects, both serum and urinary levels of aluminium are significantly higher in hemodialysis patients than in controls; a significant positive correlation was found between serum and urinary levels of aluminium. In autopsy specimens, aluminium levels were higher in the dialysis group than controls for all tissues; the differences were statistically significant except in heart and urine. Tissue concentrations of aluminium in the two groups were then analysed separately both in uremic patients and controls. The high...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.
