Task-dependent ethanol effects on escape in rats bred for ethanol sensitivity

Pharmacology, Biochemistry, and Behavior
M B Bass, D Lester


Lines of rats selectively bred for differences in degree of locomotor depression by ethanol were tested for ethanol-induced impairment of jumping to a descending platform to escape 0.3 mA shock. The MA ("most affected") line showed greater decreases in height jumped than the LA ("least affected") line at IP doses of 1.25, 1.75, and 2.25, but not at 0.75 g ethanol/kg. MA rats also showed greater increases in latency to first jump (at 1.75 and 2.25 g/kg) which largely accounted for the line difference in decrease in height jumped. Males showed greater impairment than females on both measures. While extending the greater ethanol sensitivity of MA than LA rats to impairment of an escape response, the results contrast with previous studies of water escape where the LA line showed greater impairment than the MA line.

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.
