Abstract

The reduction of acute toxicity of paraquat dichloride (PQ) in mice was studied by several sodium sugar sulfates such as dextran sulfate (DS), cellulose sulfate (CS), chondroitin sulfate (CDS), sucrose sulfate (SS) and glucose sulfate (GS). When sugar sulfates (DS, CS, SS or GS, 2,000 mg/kg) were given orally immediately after PQ ingestion (200 mg/kg), the survival rates were 100% respectively on the 14th day after PQ ingestion. In the case of CDS, it was 73%. The effective dose of SS and GS given for the prevention of PQ toxicity in mice after PQ (200 mg/kg) ingestion was more than 400 mg/kg for SS-treated group and more than 800 mg/kg for GS-treated group. The survival rate of these mice was 100% respectively. When GS or SS (2,000 mg/kg) was given orally to mice within 1 h (0, 10, 20, 30 or 60 min) after PQ ingestion (200 mg/kg), the survival rates in an earlier treatment were greater than those in a later treatment. The measurement of serum PQ concentrations in mice suggested that a mechanism for the prevention of PQ toxicity by the administration of sugar sulfates may be inhibition of PQ absorption, and/or stimulation of PQ excretion from intestine. The effectiveness of SS and GS in preventing PQ toxicity was similar to tha...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.
