We aimed to examine whether resistancetraining and berberine supplementation can protect the hippocampus against berberine-inducedneural toxicity.Methods: Fifty-six male Wistar rats were assigned randomly into eight groups of seven including:Control (Ctrl), Sham (normal saline), T1 (diazinon + berberine chloride (2 mg/kg) + resistancetraining), T2 (diazinon + berberine chloride [15 mg/kg] + resistance training), T3 (diazinon), T4(diazinon +resistance training), T5 (diazinon + berberine chloride [2 mg/kg]), and T6 (diazinon+ berberine chloride [15 mg/kg]). In the experimental groups, diazinon was intraperitoneallyadministered at a dose of 1.5 mg/kg. In the training groups, rats were trained every three days for sixweeks and 8-12 dynamic movements (repetitions) during each climb (six climbs for two sets). Theexpression of hippocampus PI3K and CDK genes and TrkB and ERK protein levels were evaluated inthe brain of diazinon-treated rats.Results: The protein expression of ERK and TrkB were increased following the treatment of diazinonintoxicated rats with berberine and resistance training (P=0.001). The administration of berberineat a dose of 15 mg/kg in combination with resistance training significantly (P=0.001) decreasedthe cell death rate in the hippocampus. Diazinon treatment caused extensive apoptosis in thehippocampus region of the rats’ brain (P=0.001). The gene expression of PI3K and CDK wassignificantly increased and the cell death rate significantly decreased (P=0.001) in the hippocampusfollowing the treatment of rats with berberine and resistance training.Conclusion: Six weeks of resistance training in combination with berberine treatment significantlyreduced apoptosis in the hippocampus region of diazinon-intoxicated rats. It seems theneuroprotection effects of berberine and resistance training are mediated by the stimulation of theexpression of enzymes responsible for the antioxidant defense within neuronal cells","PeriodicalId":33222,"journal":{"name":"International Clinical Neuroscience Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42626855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The phenotype and genotype of lipid metabolism disorders are heterogeneous and divided into two major groups. Constant or progressive proximal and axial muscle weakness associated with or without metabolic crisis, is often seen in patients with LSM such as primary carnitin deficiency (PCD) or multiple acyl-coenzyme a dehydrogenase deficiency disorder (MADD). On the other hand, rhabdomyolysis triggered by fasting, fever, or physical activity usually occurs in patients with disorders affecting intramitochondrial fatty acid transport and β-oxidation, such as carnitine palmitoyltransferase II deficiency (CPT2), mitochondrial trifunctional protein deficiency and very-long-chain acyl-CoA dehydrogenase deficiency (VLCAD). \u0000Methods: In this cross-sectional study, we summarized the clinical profiles and muscle histology of 64 Iranian patients diagnosed with LSM by muscle biopsy. These patients were selected from 3000 patients referred for muscle biopsy to Toos and Mofid children’s hospitals during 2010 to 2016. Their affected siblings were also added to the study. \u0000Result: In our study 45.3% of the patients were men and 54.7% were women. Mean age of the patients was 27.05 years (SD: 14.26) and the mean age of onset of symptoms in these patients was 20.94 (SD: 14.25) years.  Most patients (70.3%) had proximal weakness and no bulbar involvement. Only 9.3% of the patients had a positive family history. \u0000Conclusion: LSMs are not incommon in Iran and their phenotype can mimic inflammatory myopathy or limb girdle muscular dystrophy.

In this study, forward kinematics and Jacobian matrix calculated for two single-port robots for comparing the effectiveness of two types of single port minimal invasive surgical robots to ablation and resection of brain tumorMethods: The motion analysis of robots type 1 and 2 has compared to each other. Ablation manipulator in robot type 1 has five degrees of freedom, but in robot type 2, three revolute degrees of freedom of this manipulator has replaced with a revolute joint perpendicular to the previous three revolute joints.Results: Results showed that for resection surgery, in the same conditions, robot type 2 damaged 58.9 mm3 more of cerebral cortex tissue than robot type 1 to resect the brain tumors. To establish a static balance, robot type 2 needs to tolerate at least 41% more internal loading than robot type 1. The maximum velocity for robot type 1 in the contact location between the end-effector and the tumor is 1.7 times more than robot type 2. The maximum end-effector force of robot type 1 to apply the tumor for ablation surgery is more than 1.8 times in robot type 2, but the maximum moment and power for ablation surgery and resection of these two robots were the same less than 1% difference.Conclusion: Despite the more straightforward mechanism, a minimum number of joints, and better kinematics range of robot type 2, robot types 1 has the possibility for transformation, establishes the static balancing, and does a better ablation surgery with less damage to the brain.","PeriodicalId":33222,"journal":{"name":"International Clinical Neuroscience Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43161187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Schizophrenia is a combination of hallucinations, delusions, and mental disorders, that the severity of them impairs normal thinking and behavior, and in general the inability to perform daily activities. Behavioral, intellectual, and emotional disorders indicate the widespread impact of Schizophrenia on various aspects of mental health. The signs and symptoms of schizophrenia are very varied, although delusions, hallucinations, or disorganized speech are included in common symptoms. Dopamine has been the main subject of much research on schizophrenia for decades. Molecular neuroimaging studies to explore the Dopamine System (DA system) in vivo have revealed that schizophrenia is first associated with a defect in the striatum and then with a defect in extrastriatal regions with centralizing on Cortex and midbrain. Also, the Gamma-Aminobutyric acid (GABA) mRNA dysregulation and Neuroinflammatory mechanisms can be effective in schizophrenia. Various medications such as antipsychotic drugs are used to the aim of treating this disease but they can just decline or improve the positive symptoms. Modeling of neurodevelopment and synaptic connection defects by induced human pluripotent stem cells have made appropriate circumstances to the elimination of schizophrenia treatment barriers. With the development of cell therapies and the usage of induced pluripotent stem cells, there is a hope that the negative symptoms can be improved by this approach.","PeriodicalId":33222,"journal":{"name":"International Clinical Neuroscience Journal","volume":"7 1","pages":"171-178"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47368045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Astrocytes were treated with different concentrations of 0-50 μg/ml from MTX, PTX, the MTX-PTX mixture, PTX-loaded NPs, MTX-loaded NPs, and PTX-MTX co-loaded NPs for 48 hours.
