1. A single oral dose of either [(14)C]Prefix or 2,6-dichlorobenzo[(14)C]nitrile to rats is almost entirely eliminated in 4 days: 84.8-100.5% of (14)C from [(14)C]Prefix is excreted, 67.3-79.7% in the urine, and 85.8-97.2% of (14)C from 2,6-dichlorobenzo-[(14)C]nitrile is excreted, 72.3-80.7% in the urine. Only 0.37+/-0.03% of the dose of [(14)C]Prefix and 0.25+/-0.03% of the dose of 2,6-dichlorobenzo[(14)C]nitrile are present in the carcass plus viscera after removal of the gut. Rats do not show sex differences in the pattern of elimination of the respective metabolites of the two herbicides. The rates of elimination of (14)C from the two compounds in the 24hr. and 48hr. urines are not significantly different (P >0.05) from one another. 2. After oral administration to dogs, 85.9-106.1% of (14)C from [(14)C]Prefix is excreted, 66.6-80.9% in the urine, and 86.8-92.5% of (14)C from 2,6-dichlorobenzo[(14)C]nitrile is excreted, 60.0-70.1% in the urine. Dogs do not show sex differences in the pattern of eliminating the metabolites of either Prefix or 2,6-dichlorobenzonitrile. 3. Dogs and rats do not show species differences in the patterns of elimination of the two herbicides. 4. Prefix and 2,6-dichlorobenzonitrile are completely me...Continue Reading

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.

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.

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.
