Neostigmine and pilocarpine attenuated tumour necrosis factor alpha expression and cardiac hypertrophy in the heart with pressure overload.

Logáil Isteach / Cláraigh
The inflammatory cytokine tumour necrosis factor alpha (TNF alpha) is known to be a major factor contributing to cardiac remodelling and dysfunction. Parasympathetic nervous system cholinergic function can inhibit TNF alpha expression during systemic infection. In the present study, we tested the

Status epilepticus triggers caspase-3 activation and necrosis in the immature rat brain.

Logáil Isteach / Cláraigh
The mode and mechanism of neuronal death induced by status epilepticus (SE) in the immature brain have not been fully characterized. In this study, we analyzed the contribution of neuronal necrosis and caspase-3 activation to CA1 damage following lithium-pilocarpine SE in P14 rat pups. By electron

Diverse effects of variant doses of dexamethasone in lithium-pilocarpine induced seizures in rats.

Logáil Isteach / Cláraigh
Corticosteroids are used in the management of several epileptic aliments; however, their effectiveness in combating seizures remains controversial, with pro- and anti-convulsive effects ascribed. The current study aimed to address the modulatory effect of dexamethasone (DEX) utilizing 3 dose levels

Ultrastructural identification of dentate granule cell death from pilocarpine-induced seizures.

Logáil Isteach / Cláraigh
Cell loss in the hippocampal formation is a common event in patients with temporal lobe epilepsy. The belief that dentate granule neurons are relatively resistant to excitotoxic injury has recently been challenged both, in epileptic patients and in animal models of temporal lobe epilepsy. The nature

The novel GLP-1/GIP dual receptor agonist DA3-CH is neuroprotective in the pilocarpine-induced epileptogenesis rat model.

Glia-mediated neuro-inflammation and oxidative stress-induced neuronal apoptosis can contribute to epileptogenesis. We have demonstrated previously that mimetics of glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP) and dual-GLP-1/GIP receptor agonists
Recently, more and more studies support that inflammation is involved in the pathogenesis of epilepsy. Although TGFβ signaling is involved in epileptogenesis, whether TGFβ-associated neuroinflammation is sufficient to regulate epilepsy remains unknown to date. Furthermore, tumor necrosis factor-α
Magnetic resonance imaging (MRI) is a useful noninvasive tool used to detect lesions in clinical and veterinary medicine. The present study evaluated the suitability of a new easy-to-use compact MRI platform (M2 permanent magnet system, Aspect Imaging, Shoham, Israel) for assisting with preclinical

Lithium-pilocarpine-induced status epilepticus produces necrotic neurons with internucleosomal DNA fragmentation in adult rats.

Logáil Isteach / Cláraigh
Prolonged and continuous epileptic seizures [status epilepticus (SE)] produce a widespread pattern of neuronal death, primarily in limbic brain regions. Because it has been suggested that seizure-induced neuronal death may be apoptotic in nature, we tested the hypothesis that

Early Chronic Carbamazepine-in-Food Administration to MAM/Pilocarpine Rats Does Not Affect Convulsive Motor Seizures.

Logáil Isteach / Cláraigh
Antiepileptic drug-resistance is a major health problem in patients with cortical dysplasia (CD). Whether drug-resistant epilepsy is associated with progressive brain damage is still debated. We previously generated a rat model of acquired CD, the methylazoxymethanol-pilocarpine (MP) rat, in which
Lithium-pilocarpine-induced status epilepticus (SE) leads to the genesis of massive neuronal loss in adult rats and to a lesser extent in P21 rats. Neuronal damage occurs mainly via a process of necrosis in limbic forebrain, cerebral cortex, thalamus, and substantia nigra. It is not known, however,

[Relationship between programmed cell death mechanisms and neuronal necrosis induced by seizures].

OBJECTIVE To clarify if programmed cell death mechanisms induced by seizures take part in the necrotic process of neurons. METHODS Seizure was induced by pilocarpine (P) in Sprague-Dawley adult rats which were allowed to recover for 24 or 72 hours before perfusion-fixation. Neuronal death was
BACKGROUND Status epilepticus (SE) induces severe vasogenic edema in the piriform cortex (PC) accompanied by neuronal and astroglial damages. To elucidate the mechanism of SE-induced vasogenic edema, we investigated the roles of tumor necrosis factor (TNF)-α in blood-brain barrier (BBB) disruption

Calpain I activity and its relationship with hippocampal neuronal death in pilocarpine-induced status epilepticus rat model.

Logáil Isteach / Cláraigh
This study aims to establish pilocarpine-induced rat model of status epilepticus (SE), observe the activity of calpain I in the rat hippocampus and the subsequent neuronal death, and explore the relationship between calpain I activity and neuronal death in the hippocampus. Fifty-eight adult male

Caspase-3 is not activated in seizure-induced neuronal necrosis with internucleosomal DNA cleavage.

A caspase-3-activated DNase produces internucleosomal DNA cleavage (DNA laddering). We determined whether caspase-3 is activated by lithium-pilocarpine-induced status epilepticus in six brain regions with necrosis-induced DNA laddering. The thymuses of adult rats given methamphetamine or normal

OBJECTIVE To determine definitively the morphology of neuronal death from lithium-pilocarpine (LPC)-and kainic acid (KA)-induced status epilepticus (SE), and to correlate this with markers of DNA fragmentation that have been associated with cellular apoptosis. Endogenous glutamate release is
