Abstract

The distribution and excretion of radioactivity from [14C]citrinin (3 mg/kg, i.v) was determined in male rats. At 0.5 h after administration maximum values of 14.7% and 5.6% of total radioactivity were observed in the liver and kidneys, respectively, and by 6 h decreased to 7.5% in the liver and 4.7% in the kidney. Plasma concentration of 14C decreased from 9.2% at 0.5 h to 4.7% at 6.0 h. 2 plasma elimination rates were observed, with half-lives of 2.6 and 14.9 h, respectively. Approximately 80% of the administered 14C activity was excreted in feces and urine by 24 h after administration. A second group of rats was pretreated with 50 mg/kg of citrinin, i.p., 4 days prior to administration of 3 mg/kg [14C]citrinin, i.v. 30% of the pretreated animals died and the remaining animals were divided into 2 groups on day 4 after pretreatment; rats which were "nephrotoxic" and rats which had "recovered" from the initial insult of citrinin. Proteinuria and glucosuria as well as enhanced urine output were observed in "nephrotoxic" rats 4 days after pretreatment. 24 h after [14C]citrinin, only 13% of 14C activity was detected in the urine of "nephrotoxic" rats. The plasma disappearance curve had 2 elimination rates, with half-lives of 0.6 a...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.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Rh Isoimmunization

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Discover the latest research on Rh Isoimmunization here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.

Enzyme Evolution

This feed focuses on molecular models of enzyme evolution and new approaches (such as adaptive laboratory evolution) to metabolic engineering of microorganisms. Here is the latest research.

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.

Pharmacology of Proteinopathies

This feed focuses on the pharmacology of proteinopathies - diseases in which proteins abnormally aggregate (i.e. Alzheimer’s, Parkinson’s, etc.). Discover the latest research in this field with this feed.

Alignment-free Sequence Analysis Tools

Alignment-free sequence analyses have been applied to problems ranging from whole-genome phylogeny to the classification of protein families, identification of horizontally transferred genes, and detection of recombined sequences. Here is the latest research.
