Cannabidiol (CBD), the main nonpsychotomimetic compound from Cannabis sativa, inhibits experimental seizures in animal models and alleviates certain types of intractable epilepsies in patients. Its pharmacological profile, however, is still uncertain. Here we tested the hypothesis that CBD anticonvulsant mechanisms are prevented by cannabinoid (CB1 and CB2) and vanilloid (TRPV1) receptor blockers. We also investigated its effects on electroencephalographic (EEG) activity and hippocampal cytokines in the pentylenetetrazole (PTZ) model...

Despite long use of antiepileptic drugs, it remains a challenge to achieve seizure control while reducing adverse effects and preventing cognitive impairment. Several lines of evidence suggest a role of vitamin D in epilepsy. So this study aimed to investigate the effect of vitamin D on epileptogenesis, cognitive dysfunction and antiepileptic activity of lamotrigine, in a rat model of chemical kindling. Rats were kindled by pentylenetetrazole injections every other day over four weeks, together with daily oral treatment by either vehicle, vitamin D, lamotrigine or combination of vitamin D and lamotrigine...

PURPOSE: To examine associations between health-related quality of life (HRQoL) and anxiety symptoms across anxiety domains (obsessions/compulsions, social anxiety, panic disorder, agoraphobia, separation anxiety, physical injury fears, generalised anxiety, and posttraumatic stress) in a general adolescent population. Expanded knowledge about these associations can provide valuable information for improving interventions and prevention strategies for adolescent anxiety. METHODS: Cross-sectional data about anxiety were collected via a school survey from a community sample of Norwegian adolescents aged 12-17 (N = 1719)...

THIP (4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol) is a GABAA receptor agonist with varying potencies and efficacies at γ-subunit-containing receptors. More importantly, THIP acts as a selective superagonist at δ-subunit-containing receptors (δ-GABAA Rs) at clinically relevant concentrations. Evaluation of THIP as a potential anticonvulsant has given contradictory results in different animal models and for this reason, we reevaluated the anticonvulsive properties of THIP in the murine pentylenetetrazole (PTZ) kindling model...

BACKGROUND: Children with specific learning disabilities (SpLD) are likely to develop self-stigma and have a poor quality of life (QoL) because of their poor academic performance. Although both self-stigma and poor QoL issues are likely to be found in low academic achievers without SpLD, children with SpLD have worse situation because their diagnosis of SpLD suggests that their learning struggles are biological and permanent. Specifically, students' perception of own capabilities may be affected more by the diagnosis of SpLD than their own actual performance...

Purpose: The pleiotropic effects of statins (antioxidant and anti-inflammation) have been reported by previous studies. Therefore, we aimed to determine whether pitavastatin has protective effects against pentylenetetrazol (PTZ)-induced kindling in mice and also whether pitavastatin improves the brain antioxidant capacity and attenuates the oxidative injuries in kindled mice. Methods: Twenty-four mice were randomly divided into four groups (each group n=6); control, PTZ-kindling and PTZ-kindled rats treated with pitavastatin (1&4 mg/kg)...

In order to develop phenyl sulfonamides as a novel class of anti-epileptic drugs (AED) for both general and partial seizure, we initiated in vivo screening of our chemical library in the mice MES and sc-PTZ models and found compounds 1 and 2 as lead compounds. Optimization of 1 and 2 led to the discovery of compound 21, which showed potent anticonvulsant effect in MES, scPTZ and rat amygdala kindling models. These findings indicate that compound 21 could be a useful new broad spectrum AED like sodium valproate and provide an opportunity to struggle current therapy-resistant epilepsy...

OBJECTIVE: Quantitative assessments of extracellular EEG to identify specific features of three main phases of seizure acquisition based on kindling model in Rat. METHODS: Male rats were divided into 2 groups including kindled (n=10) and sham (n=7) and respectively underwent an amygdala rapid kindling and placebo kindling. EEG signals in stages 1-2 (initial seizure stages (ISSs)), 3 (localized seizure stage (LSS)), and 4-5 generalized seizure stages (GSSs) were divided into 5 bands: delta (0-4Hz), theta (4-8Hz), alpha (8-12Hz), beta (12-28Hz), and gamma (28-40Hz)...

INTRODUCTION: Epileptogenesis is a process of seizure development. Lamotrigine is a novel antiepileptic drug which is also used for antiepileptogenic research. Kindling models are recommended as potentially useful tools for antiepileptogenic treatment discovery. However, previous studies demonstrated that the antiepileptogenic effect of lamotrigine is controversial in the electrical kindling model. Chemical kindling such as with pentylenetetrazole is another kindling model. The aims of this study were to examine whether lamotrigine could prevent the development of seizure in pentylenetetrazole kindling rats...

Connexin (Cx) 36 is known to be a component of gap junctions, and has been suggested to play an important role in epilepsy. In order to determine dynamic changes of Cx36 protein expression in epilepsy and investigate the role of Cx36 in electroencephalographic activity and pathogenesis, we utilized kainic acid (KA) to induce epileptogenesis. We found that epileptic discharges began 71.8 ± 23.7 s after KA administration. Spike frequency and amplitude of epileptiform activity reached maximal levels at 30 ± 5...

A properly mounted immune response is indispensable for recognizing and eliminating danger arising from foreign invaders and tissue trauma. However, the 'inflammatory fire' kindled by the host response must be tightly controlled to prevent it from spreading and causing irreparable damage. Accordingly, acute inflammation is self-limiting and is normally attenuated after elimination of noxious stimuli, restoration of homeostasis and initiation of tissue repair. However, unresolved inflammation may lead to the development of chronic autoimmune and degenerative diseases and cancer...

The biologic processes underlying epileptogenesis following a brain insult are not fully understood, but several lines of evidence suggest that hyperphosphorylation of tau may be an important factor in these processes. To provide further insight into the causal relationship between tau and epileptogenesis, this study applied amygdala kindling to rTg4510 mice that, concurrent with other pathologies, overexpress phosphorylated tau, tau knockout mice, or their respective wild-type controls. Mice were electrically stimulated twice daily, 5 days per week for 3 weeks...

Epilepsy is one of the most common neurologic disorders worldwide with no distinguishable cause in 60% of patients. One-third of the world population has been infected with Toxoplasma gondii. This intracellular parasite has high tropism for excitable cells including neurons. We assessed impact of acute and chronic T. gondii infection on epileptogenesis in pentylenetetrazole (PTZ) kindling model in male rats. T. gondii cysts were administered to rats by intraperitoneal (i.p.) injection. The presence of T. gondii cysts in the brain of rats was verified by hematoxylin-eosin staining...

New graduate nurses (NGNs) are not fully prepared to recognize and react to rapidly declining patient conditions. Academic curricula typically do not target education related to rapid response events. A study was conducted to evaluate if a collaborative simulation between senior nursing students and NGNs would develop and improve the knowledge and skills needed to recognize and react to a patient who is rapidly deteriorating. Outcomes showed that participants made gains in the areas of competence, prioritization, and communication...

Amygdala kindling is a common temporal lobe-like seizure model. In the present study, temporal and spectral analyses of the ictal period were investigated throughout amygdala kindling in response to different behavioral seizures. Right-side amygdala was kindled to induce epileptiform afterdischarges (ADs). ADs of both the frontal cortex and amygdala were analyzed. Powers of the low (0-9 Hz)- and high (12-30 Hz)-frequency bands in response to different behavioral seizures were calculated. Densities of upward and downward peaks of spikes, which reflected information of spike count and spike pattern, throughout kindle-induced ADs were calculated...
