Abstract

Intravenous desferrioxamine (DFO) is the method commonly used to treat aluminum toxicity. This laboratory has developed a hollow fiber device with immobilized DFO, an "Aluminum DFO-HP" (DFO-HP), for the purpose of removing aluminum without the chelator (DFO) entering the blood. With Food and Drug Administration approval, a polysulfone DFO-HP, placed in the extracorporeal circuit in series with the patient's customary dialyzer, was tested for its safety and ability to remove aluminum in patients with ESRD who had aluminum overload. During treatment with this device, no toxic reactions, side effects, or hematologic or clinical laboratory changes were seen other than those associated with dialysis. Average aluminum clearance with the DFO-HP device was 25.3 mL/min with a range of 7.2 to 52.4 mL/min, whereas aluminum clearance with the F-60 polysulfone high-flux dialyzer was 8.4 mL/min. Aluminum clearance of the cuprophane dialyzers in series with the DFO-HP was negligible. The amount of aluminum removed over a 2-h treatment with DFO-HP ranged from 94 to 628 micrograms, which corresponded to 32 to 199% of the initial aluminum in the circulation before that particular treatment. The excess 99% was provided from aluminum released from...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.
