The voltage-gated calcium channel subunit α2δ-2 controls calcium-dependent signaling in neurons, and loss of this subunit causes epilepsy in both mice and humans. To determine whether mice without α2δ-2 demonstrate hippocampal activation or histopathological changes associated with seizure activity, we measured expression of the activity-dependent gene c and various histopathological correlates of temporal lobe epilepsy (TLE) in hippocampal tissue from wild-type (WT) and α2δ-2 knock-out ( KO) mice using immunohistochemical staining and confocal microscopy. Both genotypes demonstrated similarly sparse c- and expressions within the hippocampal dentate granule cell layer (GCL) at baseline, consistent with no difference in basal activity of granule cells between genotypes.

The patient group consisted of children with obesity/overweight and the control group consisted of children with normal weight.

Material And Method: Forty male Wistar rats were randomly divided into five equal groups, control, paracetamol (P), okra seed extract (AE), okra seed extract + paracetamol (P + AE), and okra seed extract + paracetamol + N-acetyl cysteine (NAC) (P + AE + N). AE was administered by oral gavage through a gastric tube at 600 mg/kg/day for seven days.
Article Synopsis
- * Even though knockout (KO) mice showed fewer active cells in the dentate gyrus after handling-induced seizures, they exhibited increased activation when given a low dose of a seizure-inducing drug compared to wildtype (WT) mice, indicating heightened sensitivity to convulsions.
- * Histopathological markers, such as neurogenesis and glial activation, were largely similar in both KO and WT mice, except for a notable increase in hilar mossy cell density in KO mice,
Objective: The purpose of this study was to investigate the serum levels of mitochondrial metabolism/reactive oxygen species (ROS)-related peptides (hypoxia inducible factor-1α [HIF-1α], fibroblast growth factor-21 [FGF-21], growth differentiation factor-15 [GDF-15]) and key migraine-related neuropeptides (calcitonin gene-related peptide [CGRP], pituitary adenylate cyclase-activating peptide-38 [PACAP-38], substance P [SP], and vasoactive intestinal peptide [VIP]) during migraine attacks and to evaluate their diagnostic value in pediatric migraine.
Background: There is increasing evidence for the important role of impairment in oxidative mitochondrial metabolism in the pathophysiology of migraine. Potential biomarkers that may reflect the relationship between migraine and mitochondrial dysfunction are unclear.
