Objective: Inositols play significant roles in biological systems. Myo-inositol (MI), the most prevalent isomer, functions as an osmolyte and mediates cell signal transduction. Other notable isomers include Scyllo-inositol (SCI) and D-Chiro-inositol (DCHI).

Connectivity of toxigenic Pseudo-nitzschia species assemblages between the Northeast U.S. continental shelf and an adjacent estuary.

Harmful Algae

Pseudo-nitzschia harmful algal blooms have recently caused elevated domoic acid in coastal environments of the Northeast United States. In 2017, the toxigenic species P. australis was observed in Narragansett Bay, Rhode Island, a temperate estuarine ecosystem, for the first time since 2009 when DNA monitoring for Pseudo-nitzschia species began.

The long-term effects of limbic non-convulsive status epilepticus in peri-adolescent rats.

Electronic address:

To optimize the clinical approach to non-convulsive status epilepticus (NCSE), it is essential to gain insight into its long-term effects on cognition and behaviors. Here, we investigated limbic NCSE-induced hippocampal injury and behavioral deficits in peri-adolescent rats. NCSE was induced in P43 Sprague Dawleyrats with intrahippocampal subconvulsive doses of kainic acid (NCSE group, n = 14) under continuous epidural cortical electroencephalography (EEG).

Bacterial Lipopolysaccharide Post-Conditioning in The kainic acid animal model of Temporal Lobe epilepsy.

Epilepsy Behav

Electronic address:

This study used intra-hippocampal injections of Kainic Acid (KA) in Wistar rats to induce spontaneous recurrent seizures (SRS) after a 9-day latent period. A post-conditioning protocol with LPS, injected at the same site 72 h after the initial KA insult, was employed to trigger secondary competing processes. To evaluate the post-conditioning effect of LPS, 25 animals were divided into four groups: SAL-SAL (n = 6), KA-SAL (n = 6), SAL-LPS (n = 7), and KA-LPS (n = 6).

Objective: Structural epilepsies can manifest months or years after the occurrence of an initial epileptogenic insult, making them amenable for secondary prevention. However, development of preventive treatments has been challenged by a lack of biomarkers for identifying the subset of individuals with the highest risk of epilepsy after the epileptogenic insult.

Methods: Four different rat models of epileptogenesis were investigated to identify differentially expressed circulating microRNA (miRNA) and isomiR profiles as biomarkers for epileptogenesis.
