Quercetin (SNPC) is a compound with both anti-inflammatory and anti-oxidant effects, which can cross the blood brain barrier. The aim of the present study was to evaluate neuroprotective effect of quercetin in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced model of PD in male mice. Materials and Methods: 48 male NMRI mice were divided into 6 groups (n=8); control, saline, MPTP, MPTP+ 20mg/kg quercetin, MPTP+ 25mg/kg quercetin, and MPTP+ 30mg/kg quercetin. To induce PD model, MPTP (25mg/ Kg) was injected intraperitoneally (i.e.) for 4 day. Catalepsy test was assessed by test bars one and 21 days after the last injection MPTP. Quercetin (20, 25, 30mg/kg/day) was applied orally for 21 days. Dopaminergic neurons of SNPC were determined by immunohistochemical labeling. The levels of interleukin 10 and TNF-α were determined in the substantia nigra and the striatum using ELISA technique. Results: Treatment with quercetin was significantly improved catalepsy. Furthermore, quercetin significantly enhanced the number of neurons in SNPC, increased interleukin 10 protein levels, and reduced TNF-α protein values. Conclusion: Quercetin may exert a neuroprotective effect on progressive cell damage and the neuronal death in the substantia nigra in PD; possibly via modulation of inflammatory mediators.

Stress can be a risk factor for long-term depression. It also suggests that depression plays a role in developing dementia. Amnesia is the most problem in dementia. Is amnesia a risk factor for depression? Considering the common underlying mechanisms for causing these disorders, the purpose of this study is to investigate the role of amnesia in developing depression. Materials and Methods: Forty-eight wistar rats were divided into two main groups (sham-A and intervention-B) and four subgroups (Control-C, Chronic mild stress-D, hypoperfusion without stress-E, hypoperfusion with Mild stress-F). Permanent occlusion of bilateral common carotid artery was performed to induce cerebral hypoperfusion. Radial arm maze test and chronic unpredictable mild stress were used to evaluate amnesia and depression, respectively. Forced swim test was performed to assess severity of depression and finally we used neuronal count for evaluating cellular degeneration in the CA1 hippocampus region. Results: Cerebral hypoperfusion causes amnesia and significantly reduced the mean number of cells in the hippocampal CA1 area. Cerebral hypoperfusion and stress significantly increased the incidence of depression-like behavior. Conclusion: Amnesia caused by cerebral hypoperfusion can increase the risk of depression, especially under stressful situations. 2034 Basic research in Neuroscience Comparison of the Effectiveness of Sertraline, Transcranial Direct Stimulation Current and their Combination on Post-Traumatic Stress Disorder in Veterans Sarhadi Shabnam Ghaemi Fatemeh Dortaj Fariborz Delavar Ali Department of Psychology, Factuly of Literature, Humanities and Social Science, Science and Research Branch, Islamic Azad University, Tehran, Iran Ministry of Health and Medical Education, Deputy of Health, Tehran, Iran Department of Educational Psychology, Faculty of Psychology and Educational Sciences, Allameh Tabataba'i University, Tehran, Iran Department of Educational Psychology, Faculty of Psychology and Educational Sciences, Allameh Tabataba'i University, Tehran, Iran 1 12 2019 8 1 51 62 20 02 2020 20 02 2020 Introduction: Traumatic Stress Disorder (PTSD) is one of the most prevalent health problems in the victims of the Iran-Iraq war. Despite many advantages of the administration of selective serotonin reuptake inhibitors, as the first-line treatment of PTSD, a large number of the patients still need more effective therapies. The purpose of this study was to comparison of the effectiveness of sertraline, transcranial direct stimulation current (TDCS), and the combined treatment (TDCS and sertraline) to relieve the symptoms of PTSD in the veterans in Tehran, Iran. Materials and Methods: The current study was a semi-experimental study including pre- and post-tests, a control group, and three-month follow-up. The population of study was veterans who lived in Tehran in 2018. 68 veterans were selected by purposive sampling method and then randomly divided to control and experimental groups. The first group was treated with sertraline, the second group received TDCS, and the third group treated with the combined treatment. The PTSD Checklist for DSM-5(PCL-5) was used as a research tool. Results: All of the treatment approaches were effective in reduction of symptoms in patients with PTSD. In the post-test and follow-up phase, there was a significant difference in PCL-5 scores between sertraline, TDCS, and combined treatment in comparison with the control group. Combined treatment (TDCS and sertraline) have shown a significantly higher and persistence effectiveness. Conclusion: Combined treatment with TDCS and sertraline can be used as an efficient and effective approach to reduce PTSD symptoms in veterans. 2033 Basic research in Neuroscience The Effect of Pilates Training and Electrical Stimulation on Motor and Cognitive Function of Women with Multiple Sclerosis Ghorbanian Bahloul Saberi Yousef Rasouli Maryam Department of Sport Sciences, Faculty of Education and Psychology, Azarbaijan Shahid Madani University, Tabriz.

Iran 1 12 2019 8 1 63 76 20 02 2020 20 02 2020 Introduction: Multiple Sclerosis (MS) is a chronic, debilitating nervous system disease, which damages the myelin of the central nervous system. The purpose of this study was to investigate the effect of 8 weeks Pilates training and direct transcranial stimulation (tDCS) on motor and cognitive functions in women with MS. Materials and Methods: The present study was a semi-experimental one in which the women with MS in Tabriz, Iran were selected and 36 of them were selected as subjects with age range of 20-40 years. They were randomly divided into four groups; Pilates + tDCS, Pilates + Placebo, tDCS, and control groups. The Pilates and tDCS training program consisted of 8 weeks (three sessions/60 minutes) Pilates training plus 20 minutes of electrical stimulation. Results: The results have shown that after exercise and electrical stimulation, the tDCS + exercise and exercise + placebo groups improved motor functions (general endurance, general speed, flexibility, balance). The results also revealed that among the measured cognitive factors, there was a significant improvement in the cognitive flexibility in the tDCS + exercise, the exercise + placebo, and the tDCS groups. Conclusion: Considering the combined effects of exercise with tDCS on motor functions, it seems that the use of these two techniques is helpful in improving motor functions in MS patients. However, this combined therapy can not improve cognitive functions of patients with MS. 2042 Basic research in Neuroscience The Role of Behavioral Activation Group Therapy on Ineffective Attitudes Rate and Rumination in Women with Insomnia Disorder Tahmasebi Zadeh Zohreh Homaei Rezvan Department of Psychology, Ahvaz Branch, Islamic Azad University, Ahvaz, Iran Department of Psychology, Ahvaz Branch, Islamic Azad University, Ahvaz, Iran 1 12 2019 8 1 77 85 24 02 2020 24 02 2020 Introduction: Sleep disorder seriously affects cognitive and physical functions.

Results: The results showed that after the behavioral activation group therapy, the mean scores of ineffective attitude and rumination were significantly different in the experimental group compared to the control group. Conclusion: Our data indicate that behavioral activation group therapy reduces ineffective attitudes and rumination in people with insomnia disorder. 2043 Basic research in Neuroscience Structural Model of Quality of Life in Patients with Breast Cancer: The Role of Psychological Hardiness, Religious Orientation, Perceived Social Protection and Self-Efficacy with Mediation of Resilience and Death Anxiety Farahbakhsh Beh Sara Mehrinejad Abolghasem Moazedian Ameneh Department of Psychology, Semnan Branch, Islamic Azad University, Semnan, Iran Department of Clinical Psychology, Faculty of Education and Psychology, AlZahra University, Tehran, Iran Department of Psychology, Semnan Branch, Islamic Azad University, Semnan, Iran 1 12 2019 8 1 86 98 24 02 2020 24 02 2020 Introduction: The quality of life in cancer patients has become increasingly important. The purpose of this study was to examine the predictive model of quality of life in patients with breast cancer based on psychological hardiness, religious orientation, perceived social support, and self-efficacy with mediation of resiliency and death anxiety. Materials and Methods: The research method was analytical and structural equation modeling. The statistical population in this study included all patients with breast cancer referring to Cancer Institute of Imam Khomeini and Milad hospitals in Tehran, Iran in 2018. Purposeful sampling method was used to select the sample. 300 patients with breast cancer were selected based on the criteria for entering and leaving criteria. The research tool was a general self-efficacy questionnaire of Sherer et al., multi-dimensional perceived social support questionnaire Zamet et al., Allport Religious Orientation Questionnaire, Kobasa Psychological Hardiness Questionnaire, Templar Death Anxiety Scale, The Conor-Davidson Resilience Questionnaire, and the World Health Organization Quality of Life Scale. Results: The results of the model analysis showed that the factor structure of the research scales was acceptable. The results of the conceptual model test showed that the fitting indices of the research model are in a favorable condition. Religious orientation and psychological hardiness on quality of life in patients with breast cancer have significant direct and indirect effects on resiliency and death anxiety. In addition, perceived social support and self-efficacy exhibits a significant indirect effect on death anxiety of patients. Furthermore, resiliency and death anxiety have a significant direct effect on the quality of life of patients with breast cancer. Conclusion: Our results indicate the importance of the antidote to psychological hardiness, religious orientation, and perceived social support in improvement of the quality of life of patients with breast cancer. 2044 Basic research in Neuroscience Stem Cell-Based Stroke Treatment Alavian Firoozeh Ghasemi Sorayya Department of Basic Sciences, Farhangian University, Tehran, Iran Cellular and Molecular Research Center, Shahrekord University of Medical Sciences, Shahrekord, Iran 1 12 2019 8 1 99 110 24 02 2020 24 02 2020 Introduction: Self-renewable and differentiable cells or stem cells are high-potential cells for the repair of tissue damages. Therefore, this is a promising approach to treat brain tissue damage following neurological disorders, such as stroke. Animal studies have shown the beneficial effects of various stem cells, including embryonic stem cells, inducible pluripotent stem cells, neural stem cells, and mesenchymal stem cells, in stroke recovery. The healing process may be due to replacement of damaged cells, neuroprotective effects, endogenous neurogenesis, angiogenesis, modulation of inflammation, and immune responses. Currently, stem cell-based methods have attracted the attention of many scientists and practitioners due to their curative effect on stroke. Conclusion: Although numerous clinical studies indicate that stem cells have high efficacy and safety in stroke treatment, some key issues should be considered. The positioning of these cells, survival, traceability, immunity, and cell transplantation protocols, such as the rate of usage and timing, are the challenges in stem cell-based treatment. Although the stem cell therapy is a potential new approach for treatment of stroke, further studies are still needed to improve the efficacy of this therapeutic method. This review article is a summary of current knowledge and concerns of the use of stem cells in post-stroke healing. 2038 Basic research in Neuroscience Late Life Depression as a Risk Factor for Dementia and Mild Cognitive Impairment: The Mediating Mechanisms and Processes Zeraatkar Haniyeh Department of Psychology, Faculty of Psychology and Educational Sciences, University of Tehran, Tehran, Iran 1 12 2019 8 1 111 119 22 02 2020 22 02 2020 Introduction: In recent years, the population of the elderly has risen in Iran.

In this disease, mitochondrial defects and oxidative stress lead to the enhancement of the free radicals and the death of dopamine neurons in the Sabstantia nigra. The clinical symptoms of this disease are including tremor, muscle stiffness, and inability to walk as well as cognition, memory and learning deficits. Aging increases the severity of Parkinson's disease. Conclusion: Any therapeutic strategy which can modulate antioxidant homeostasis and neuroprotection may increase the life expectancy and quality of life of patients with Parkinson's disease. 2040 Basic research in Neuroscience The Effect of Transcranial Direct Current Stimulation on Dorsolateral Prefrontal Cortex: a Review of its Role on Cognitive Functions Moslemi Bakhtiar Azmodeh Masoumeh Tabatabaei Mahmoud Alivandi Vafa Marzieh Department of Psychology, Tabriz Branch, Islamic Azad University, Tabriz, Iran Department of Psychology, Tabriz Branch, Islamic Azad University, Tabriz, Iran Department of Psychology, Tabriz Branch, Islamic Azad University, Tabriz, Iran Department of Psychology, Tabriz Branch, Islamic Azad University, Tabriz, Iran 1 12 2019 8 1 129 144 22 02 2020 22 02 2020 Introduction: The dorsolateral prefrontal cortex (DLPFC) is often selected as an excitatory target in the brain. A wide range of cognitive functions that can be modulated by the stimulation of this area makes it difficult to predict precise stimulation effect. The stimulation of DLPFC by transcranial direct current stimulation (tDCS) can be effective in modifying a wide range of cognitive activities. From a relatively simple and low-level activity, such as the attention process, to the complex cognitive functions, such as decision making and working memory, can be affected by tDCS. The effects of tDCS are very diverse and dependent on stimulation parameters, which sometimes lead to conflicting results. The aim of the present study was to investigate and identify various cognitive domains resulting from the effect of tDCS on DLPFC. Conclusion: Several complex cognitive activities are carried out by the DLPFC. The stimulation of this area by tDCS simultaneously activates multiple cognitive processes. This can lead to the facilitatation and sometimes inhibition of cognitive function, which subsequently may promote some behavior dysfunctions. To improve our understanding of the neurobiological mechanisms of tDCS on cognitive functions modulated by DPFLC, further investigations are needed.
