Ischemic neuronal death is presumably caused by glutamate-induced excitotoxicity, in which the increased glutamate release and impaired glutamate reuptake lead to glutamate accumulation. Mechanisms underlying the ischemic deficiency of astrocytic glutamate reuptake remain unclear, which we have studied by analyzing the effect of calmodulin-dependent protein kinase II (CaMK-II) and protein kinase C (PKC) inhibitions on astrocytic glutamate transporter during ischemia. Glutamate transporter current was recorded on the astrocytes in cortical slices...

Epileptiform activity in various but not all epilepsy and recording types and cerebral areas is more frequent in NREM sleep, and especially during sleep periods with high-amplitude EEG slow waves. Slow waves synchronize high-frequency oscillations: physiological activity from the theta through the gamma band usually appears during scalp-positive upstates while epileptiform activity occurs at transitory phases and the scalp-negative downstate. It has been proposed that interictal discharges (IIDs) are facilitated by the high degree of neuronal firing synchrony during slow wave transitory and downstates...

The accumulation of α-synuclein is the primary pathological hallmark of Parkinson's disease (PD). In PD patients, CpG demethylation of intron-1 has been reported to be associated with α-synuclein up-regulation. Environmental factor, for example neurotoxin, is a major etiological risk factor in PD pathogenesis. However, the role of CpG methylation in neurotoxin-induced PD has not been addressed completely yet. To explore CpG methylation associating with α-synuclein transcription and its underlying mechanisms in the neurotoxin-induced PD pathology, human neuroblastoma SH-SY5Y cells were treated with neurotoxins 6-hydroxydopamine (6-OHDA) and 1-methyl-4-phenylpyridinium (MPP(+))...

Recent years, several case-control studies reported that two polymorphisms (rs947211 and 1572913) within the PARK16 locus were associated with the Parkinson's disease (PD). However, the results were still controversial. Herein, we conducted a comprehensive meta-analysis to estimate the associations between two polymorphisms and PD. Seven databases (PubMed, Google Scholar, EMBASE, Web of Science, CNKI (China National Knowledge Infrastructure), VIP and Wanfang) were searched to identify the eligible studies. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to evaluate the associations of two polymorphisms with PD susceptibility...

Tests based on hyponeophagia phenomena are the most widely used to check the efficacy and efficiency of new-generation chronic antidepressant treatments. Even so, these tests lack strict consensus about their methodology, which reduces their validity, reproducibility and makes translatability difficult. Therefore, after an extensive literature review on this subject, we propose a methodological protocol for the Novelty-Suppressed Feeding Test to normalize this situation. Animals were induced to a reserpine-induced depression model and were then chronically treated with duloxetine, desvenlafaxine or vehicle...

Many patients of advanced Parkinson's disease (PD) suffer from intractable axial symptoms (severe gait and postural impairments), which were recently speculated to be more relevant to cholinergic degeneration in the brainstem than dopaminergic degeneration in the substantia nigra compacta (SNc). To investigate the role of the cholinergic cells of the pedunculopontine tegmental nucleus (PPTg) on motor deficits, especially the axial motor impairments, we measured and analyzed the gait performance of sham lesion rats, SNc dopaminergic lesion rats, PPTg cholinergic lesion rats, and combined lesion rats by using the CatWalk system...

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impaired social interaction, limited verbal communication and repetitive behaviors. Previous studies have shown that the level of Bcl-2 in the brain tissues of ASD patients is significantly decreased. However, the mechanisms underlie the down-regulation of Bcl-2 in ASD is still unknown. In this study, we investigated the alteration of Bcl-2 level and associated mechanisms in valproic acid (VPA) exposed ASD rats. VPA exposure resulted in ASD-like behaviors in rats, such as repetitive behavior and social interaction impairment...

Concepts organize our experiences and allow for meaningful inferences in novel situations. Acquiring new concepts requires extracting regularities across multiple learning experiences, a process formalized in mathematical models of learning. These models posit a computational framework that has increasingly aligned with the expanding repertoire of functions associated with the hippocampus. Here, we propose the Episodes-to-Concepts (EpCon) theoretical model of hippocampal function in concept learning and review evidence for the hippocampal computations that support concept formation including memory integration, attentional biasing, and memory-based prediction error...

Recent studies have demonstrated the presence of oxidative stress in insomnia patients. Uric acid (UA) is regarded as one of the most important antioxidants that may attenuate oxidative stress. The aim of our study was to investigate whether there is an alteration of serum UA levels in chronic insomnia patients. The association between sleep quality and serum UA in chronic insomnia patients was also investigated. We recruited 300 chronic insomnia patients and 300 age- and gender-matched normal controls. The uricase-PAP method was used to measure the concentration of UA both in patient and normal control subjects...

Inhibitory tagging (IT), a flexible central control mechanism based on the current task goals, reduces the cognitive conflict effect at the cued location by blocking the incompatible stimulus-response (S-R) code. However, it is unknown whether IT has a similar effect on emotional conflict. Thus, we combined the face-word Stroop task with the manipulation of inhibition of return (IOR) and used event-related potential (ERP) technology to simultaneously examine the modulation effect of IT on emotional and cognitive conflict processing...

Interleukin-8 (IL-8) is a pro-inflammatory cytokine that has been shown to play a role in inflammatory and autoimmune disorders. The objective of the present study was to assess the levels of IL-8 in rat serum, dorsal root ganglion (DRG) and the sciatic nerve following four different forms of sciatic nerve injury. The models used to induce the injury included partial sciatic ligation (PSL), chronic constriction injury (CCI), perineural inflammation (neuritis) and complete sciatic transection (CST). Mechanical and thermal hyperalgesia were detected by measuring withdrawal responses from a mechanical stimulus and withdrawal latency from thermal stimulation...

The proportion of people in the population who are elderly is rapidly increasing. In addition, dangerous alcohol consumption in this demographic is rising. Approximately 33% of all people with an alcohol use disorder are diagnosed with late onset alcoholism. However, few suitable animal models for late onset alcoholism exist, making it difficult to investigate the impact of alcoholism later in life. The current study investigated if chronic intermittent ethanol exposure via intraperitoneal injections every other day for 20days in aged, adult and adolescent male rats differentially alters body weight and impairs gross motor behavior as measured by the aerial righting reflex...

Cholinergic function is compromised in plethora of neurodegenerative disorders especially Alzheimer's disease. Increasing acetylcholine (ACh) levels has been the mainstay in majority of the therapeutic regimens, accepted for management of disease. The present study investigates the efficacy of 5-Desmethylnobiletin (DN), a polymethoxyflavone in augmenting cholinergic function using Caenorhabditis elegans as a model organism. The studies revealed significant elevation in cholinergic transmission mediated through increased levels of ACh and activity of nicotinic acetylcholine receptors (nAChR)...

Plasma membrane calcium ATPases (PMCAs) are ion pumps that expel Ca(2+) from cells and maintain Ca(2+) homeostasis. Four isoforms and multiple splice variants play important and non-overlapping roles in cellular function and integrity and have been implicated in diseases including disorders of the central nervous system (CNS). In particular, one of these isoforms, PMCA2, is critical for spinal cord (SC) neuronal function. PMCA2 expression is decreased in SC neurons at onset of symptoms in animal models of multiple sclerosis...

Hearing loss in mature ears can cause functional reorganization of the auditory cortex. The functional reorganization is speculated to negatively affect the outcome of hearing rehabilitation. Therefore, once a hearing loss occurs, it is important to provide auditory input before extensive reorganization in the auditory pathways. We investigated the neural plasticity in auditory cortex after single-sided deafness (SSD) in an adult rat model. The animals were divided into two groups: a normal hearing (NH) and the SSD group...
