Long-term effects of early status epilepticus on the acquisition of conditioned avoidance behavior in rats

Epilepsia
M R de FeoG F Ricci

Abstract

The acquisition of active avoidance behavior in a shuttle-box apparatus was studied in 45-day-old rats. In these animals a single episode of status epilepticus had been induced by the systemic administration of kainic acid (KA) or pentylenetetrazole (PTZ), when they were 10 or 25 days old. The results were compared with those obtained from animals in which, at the same ages, only saline solution had been injected. In KA-treated rats a decrement of right responses and a prolonged reaction time were observed, with these results more evident in animals treated earlier (10 days). Parallel with the behavioral alterations, the histological, morphometric and morphological examinations revealed neuronal and glial abnormalities at the neocortical level, while no lesions were found in the hippocampus. PTZ-treated rats showed no behavioral alteration nor histological abnormality. The different findings obtained after KA and PTZ injection suggest that not only status epilepticus per se, but the mechanism of action and the neurotoxicity of the convulsant agent, are very important in impairing late performances.

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.
