Objectives : Cognitive impairment is common in multiple sclerosis, but the brain MRI correlates in relapsing remitting multiple sclerosis remain controversial. The current study aimed to investigate whether cognitive decline can be predicted by global and/or regional brain atrophy. Methods : Sixty-three patients with relapsing remitting multiple sclerosis (36 men, mean age 39.9 ± 9.4 years old, mean EDSS 1.4 ± 1.2, mean disease duration 4.9 ± 4.3 years) and 46 healthy controls (21 men, mean age 37...

Objectives : The purpose of this research is to predict the cognitive impairment and to determine its correlation with retinal thickness, mainly (RFNL and GCIPL) in cases of multiple sclerosis. Methods : 60 multiple sclerosis patients and 30 age and sex-matched healthy controls were included in this study. Cognitive functions were evaluated in all study participants by the Montreal Cognitive Assessment (MoCA). OCT imaging was done to determine the thickness. The correlation between the cognitive domains of MoCA and the thickness of the retinal nerve fiber layers was analyzed by Spearman correlation...

Objectives : Opioid analgesics have been used for a long time in the treatment of acute and chronic pain. However, they have many side effects including tolerance development to a significant extent. Agomelatine, an atypical antidepressant, has been demonstrated to be effective in experimental studies on pain. However, the effect of agomelatine on morphine tolerance development and its mechanism of action are unknown. The antinociceptive effects of agomelatine, morphine and their combination were assessed in a mice model for painful diabetic neuropathy...

Objectives : Patients with coronary artery disease (CAD) concomitant with extracranial and intracranial atherosclerotic disease (EICAD) may have an increased risk of stroke and myocardial ischemic events. This study aimed to evaluate the concomitant atherosclerotic lesions in extra- and intracranial arterial beds in patients with CAD. Methods : A total of 1274 patients who underwent coronary angiography due to ischemic heart disease were included. All patients underwent ultrasound screening of the extra- and intracranial arteries before coronary angiography, and the degrees of extracranial carotid artery disease (ECAD) and intracranial cerebral artery disease (ICAD) were recorded...

Background : To verify the hypothesis that the nature of trigeminal neuralgia (TN) is an ectopic impulse induced by sodium channel modulated by cytokines, we conducted an animal study using the infraorbital nerve chronic constriction injury (CCI) model in rats. Method : The expression of Nav1.3 or IL-6 in the infraorbital nerve (ION) and trigeminal ganglion (TG) were detected by western blot and immunocytochemistry after administration of antisense oligodeoxynucleotide sequence (AS), IL-6 or Anti-IL-6...

This study aimed to evaluate the memory function in a rat model of fatty liver and to investigate the effects of statins on fatty liver, neuronal inflammation, oxidative stress and memory. In this study, 24 male rats were used and were divided into four groups consisting of 6 animals in each. Of them, 12 rats received liquid diet containing 35% fructose for 8 weeks in order to induce hepatosteatosis, while other animals had a normal nutrition. Group 1 served as controls and had a normal nutrition with no drug treatment...

Background : In this study, we investigate the neuroprotective effects of Hesperetin (Hst) and Nano-Hst on anxiogenic-like behavior and cerebral antioxidant defenses at transcriptional and enzymatic levels in a streptozotocin (STZ)-induced Alzheimer rat model. Methods : Wistar rats were administrated with Hst and Nano-Hst (10 and 20 mg/kg/d) for three weeks. The elevated plus-maze test assessed anxiogenic-like behavior. After behavioral test, activity and gene expression of catalase (CAT), superoxide dismutase (SOD), glutathione reductase (GRx) enzymes, as well as malondialdehyde (MDA) and glutathione (GSH) levels, were measured in the cerebral cortex...

Objectives : FOSL1 is overexpressed in multiple cancers including malignant glioma and contributes to different cellular processes. However, little attention has been paid to the lower grade glioma (LGG). Methods : Cox coefficients were examined to compare FOSL1 expression among different tumors types using OncoLnc. The UCSC Xena browser was used to generate Kaplan-Meier survival curves and explore the association between FOSL1 expression and overall survival (OS) in TCGA-LGG and subgroups. Results : FOSL1 expression in LGG was ranked first among 21 different cancers...

The pathophysiology of neuropathic pain is very complex. It involves several environmental and central mechanisms. In this study, we tried to assess the modulatory effect of (S)-3,4-Dicarboxyphenylglycine (DCPG), a metabotropic glutamate receptor subtype 8 (mGluR8) agonist, in a model of chronic central neuropathic pain in male rats. We used a spinal cord contusion method (T6-T8) for the induction of chronic central neuropathic pain.Male Wistar rats were randomly assigned to 5 equal groups (n = 10 per group)...

Backgroud and purpose : Soluble CD40 ligand (sCD40L) plays an important role in inflammation and autoimmune disorders. There is still a controversy regarding sCD40L in neuromyelitis optica spectrum disorders (NMOSD) and multiple sclerosis (MS). Herein the aims of this study were to evaluate the levels of sCD40L in patients with NMOSD, MS, and other noninflammatory neurological diseases; to investigate its potential relationship with laboratory parameters, glial fibrillary acidic protein (GFAP), thrombopoietin (TPO) and IL-6; and to address whether serum sCD40L levels in acute attacks of NMOSD patients were decreased after treatment with immunoglobulins, plasma exchange, or methylprednisolone...

Objective : Activation of nicotinic acetylcholine receptors (nAChRs) results in neuroprotection via a poorly understood molecular mechanism. In this study, we aimed to investigate the effect of nAChR stimulation with nicotine on the regulation of microRNA (miRNA) expression and identify the molecular pathway involved in neuroprotection. Methods : We conducted miRNA expression profiling using a microarray to identify the miRNAs regulated by nicotine. miR-132-5p expression was validated by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis...

Objectives : The critical closing pressure (CrCP) defines arterial blood pressure below which cerebral arteries collapse. It represents a clinically relevant parameter for the estimation of cerebrovascular tone. Although there are few methods to assess CrCP, there is no consensus which of them estimates this parameter most accurately. The aim of present retrospective, experimental study was to compare three methods of CrCP estimation: conventional Aaslid's formula and methods based on the cerebrovascular impedance: the established continuous flow forward (CFF) and a new pulsatile flow forward (PFF) model...
