Abstract
Background: Human need for food is one of the inherent or physiological needs that, along with the ability to eat and drink, is the most important factor of health, survival and longevity. Children with cerebral palsy suffer from severe maladjustment in the nutritional mechanism and the creation of unsafe, even risky, conditions for life, due to deficiencies in the disease. Because of the importance of Eating and Drinking Ability Classification System (EDACS) in the research and treatment of children with cerebral palsy, the purpose of this study was to determine the psychometric properties of the Persian version of this system.
Materials and Methods: After the forward and backward translation procedures and investigation of face and content validity, test–retest reliability was assessed between parents and therapists using the intra-class correlation coefficient (ICC). 130 Children (3 to 20 years, mean age 52.35 months and standard deviation 33.96; 73 boys, 57 girls) with various types of CP were classified according to EDACS by both parents and therapists.
Results: The test–retest reliability was high and significant; the ICC related to parents and occupational therapists was 0.98, and the ICC related to speech therapists (0.99) was higher than 0.90 that both of them showed high correlation.
Conclusion: The Persian version of the EDACS is found to be valid and reliable, and is suggested to be appropriate for the assessment of eating and drinking ability in children with cerebral palsy.

Abstract
Background: Recent Research has pointed to the involvement of lysyl oxidase (LOX) in the muscle development. Despite the fact, there is currently no direct evidence that lox is involved in the myogenic factors and exercise-induced hypertrophy. Therefore, the purpose of this study was to investigate the effect of lysyl oxidase inhibition on exercise-induced hypertrophy, as well as the gene expression of MyoD1, myogenin, TGF-β and LOX in FHL muscle of wistar rats.
Material and Methods: In this experimental research, 32 male Wister rats with an average weight of 220±15 were divided into four groups: resistance training, normal control, treated control and treated resistance training. Rats performed a resistance training for 8 weeks in which animals climbed a vertical ladder of 1­m and inclined at 85° with weights attached to their tails. In order to inhibit lysyl oxidase, treatment group rats received daily injection of intraperitoneal β-aminopropionitrile (120 mg/kg/day). FHL muscle was extracted to measure relative muscle weight, as well as genes expression of MyoD1, myogenin, TGF-β and LOX by real time-PCR.
Results: Relative weight of FHL muscle was decreased significantly in the treated groups with BAPN, compared with normal groups (p<0.05). Lysyl oxidase showed a significant increase compared to the normal control group following a resistance training (p<0.05). LOX gene expression in treatment groups showed a significant increase compared to normal control group (p<0.05). TGF-β gene expression in BAPN-treated groups significantly was increased (p<0.05) and Myogenin in treatment groups showed a significant decrease compared to normal control groups (p<0.05). The expression of MyoD1 gene in treatment groups was only decreased significantly in the treated control groups compared to normal control groups (p<0.05).
Conclusion: Results showed that inhibiting the lysine oxidase enzyme could affect the genes involved in hypertrophy and reduce the hypertrophy induced by resistance training.

Abstract
Background: Today, the high prevalence of diabetes and its complications are one of the most important public health issues worldwide. For this reason, finding relations between diabetes risk factors is very effective in preventing and reducing complications. For discovering these relations, the data mining methods can be used. By extracting association rules, which is one of the data mining techniques, we can discover the relations between a large numbers of variables in a disease.
Materials and Methods: The population of this study was 1046 patients with type 2 diabetes, whose data had recorded between 2011 and 2014 at the Special Clinic for Diabetes in Tehran's Imam Khomeini Hospital. After pre-processing step with SPSS19 software, 573 people entered the analysis phase. The FP-Growth algorithm was applied to the data set to discover the relations between heart attack and other risk factors using Rapid miner5 software. Relations, after extraction, were given to the doctor to confirm clinical validation.
Results: The obtained results of studying these 573 people (Including 292 (51%) women and 281 (49%) men, with age range 27 to 82 years) showed that the lack of blood pressure, creatinine and diastolic blood pressure at its normal level, despite higher systolic blood pressure level than normal, doesn't increase the probability of heart attack.
Conclusion: Using association rules is a good way of identifying relations between the risk factors of a disease. Also, it can provide new hypotheses to do epidemiological studies for researchers.

Abstract
Background: Nanotechnology offers a great chance to treat drug-resistant microbial infections. The purpose of this study was to synthesize amoxicillin-encapsulated polymeric nanoparticles and compare the antibacterial activity of this nanoformulation with pure amoxicillin.
Materials and Methods: Amoxicillin-encapsulated polymeric nanoparticles were prepared using chitosan as a polymer and alginate as cross linking agent. The obtained nanoparticles were characterized by Fourier transform infrared, dynamic light scattering and scanning electron microscopy. The antibacterial effects of the nanoparticles were evaluated using broth microdilution and well diffusion methods against some common bacterial strains involved in hospital-acquired infections.
Results: The drug-encapsulated nanoparticles were found to be spherical in shape with average size of 96 nm. These nanoparticles had a significant antibacterial effect on all tested bacteria, except for Pseudomonas aeruginosa. They also displayed stronger antibacterial activity than the nanocarrier alone or free antibiotic. The highest mean zones of growth inhibition (23.7 mm) for methicillin-sensitive Staphylococcus aureus and the smallest zone (12.5 mm) for the resistant species of this bacterium were determined. MIC of the nanoformulation against these two strains was respectively determined at 1.5 and 48 µg/ml and for Escherichia coli and Pseudomonas aeruginosa at 6.6 and 256 µg/ml.
Conclusion: The results suggest that amoxicillin encapsulation in polymer nanoparticles has the potential to increase its antibacterial activity against bacteria causing nosocomial infections.

Abstract
Background: Multiple sclerosis (MS) is a myelinating inflammation and an impairment of neuronal cell regeneration in the central nervous system with unknown causes. The aim of this study was to evaluate serum melatonin levels in the treatment of patients with multiple sclerosis.
Materials and Methods: A prospective study and a Cohort were conducted on 40 MS patients with multiple sclerosis patients referring to instituate MS in Arak city for one year. In this study, patients who were treated with interferon-moderating drugs and who had not been treated for more than one year were randomly selected. A questionnaire containing demographic information and clinical information and separation of interacting factors was completed and completed. Clinical information included MRI, VEP, EDSS (Expanded Disability Status Scale) score, and clinical symptoms. The patients also received peripheral blood samplers 3 times in 6 months intervals to measure melatonin and their melatonin levels, and then the relationship between the data obtained from the patient's clinical data, EDSS, serum melatonin levels using the software SPSS with ANOVA and Post-hoc statistical analyzed.
Results: In patients with MS, in spite of receiving drug treatment, the level of melatonin as an antioxidant decreased in second order sampling, which is consistent with the deterioration of the patient's clinical condition (EDSS test), and this is not observed in the control group.
Conclusion: According to the findings of this study, it can be argued that the level of melatonin is a measurable objective and measurable variable (with the help of ELISA) that can be used in the follow-up of these patients, along with clinical evaluations and questionnaires.

Abstract

Background and Aim: The inactivated vaccines are formulated with adjuvant to direct the host immune responses and also increase stability of the antigen. In recent years, the development of biological adjuvants and the evaluation of their ability in elicitation of immune responses against influenza virus have been considered. Hemokinin-1 (HK-1) activates T and B cells for differentiation into plasma cells, and antibody production. In this study, the effect of HK-1 for inducing humoral immune response against influenza chitosan based-nano vaccine was investigated.
Materials and Methods: Chitosan nanoparticle containing inactivated influenza antigen and chitosan nanoparticle containing the inactivated antigen formulated with HK-1 were prepared. Immune response following influenza nanoparticles vaccinations with and without the adjuvant was assessed in SPF chickens after prime and boost immunizations. Specific antibody levels against influenza were evaluated in serum samples of treatment and control groups by serological tests.
Findings: The chickens immunized with the HK-1 adjuvanted nano vaccine produced higher specific antibody titers that were sustained until the end of experiment comparable either with inactivated antigen alone or the H9N2 nanoparticles without HK-1 adjuvant. Administration of boosting had no effect on the enhancing of antibody titer.
Conclusion: The data show that the chitosan nanoparticles provide better absorption conditions and more stability and release of the influenza antigen in the presence of HK-1 biological adjuvant.

Abstract

Background and Aim: Advances in the field of medicine over the past few decades enabled the identification of risk factors that may contribute toward the development of coronary artery disease (CHD). However, this knowledge has not yet helped in the significant reduction of CHD incidence. The purpose of this study is to assess the risk factors of coronary artery heart events, after receiving stent, by competing risks with composite events tree. We can reduce CHD incidence with control of this risk factors.
Materials and Methods: This sectional study includes the Coronary Artery Disease (CAD) patients that received Percutaneous Coronary Intervention (PCI) cure with at least planting one stent from May 21, 2007 to May 22, 2009 in Tehran heart center. We followed patients for three years. Revascularization, nonfatal myocardial infarction, and cardiac death are considered as major acute cardiovascular events (outcome). We used decision tree with competing risks with composite events model for classification of patients. The data were analyzed by IBM SPSS Statistics 24 and R 3.3.3 softwares.
Findings: Four factors including fasting blood sugar, diabetes mellitus, body mass index and age established six homogeneous subgroups of patients for nonfatal myocardial infarction and revascularization. Maximum Revascularization incidence after 50 months was 17.8% and Maximum Nonfatal myocardial infarction was 9.7%.
Conclusion: CAD patients can reduce serious cardiac events by controling their weight and diabetes status, after receiving stent.

Abstract

Background and Aim: The aim of study was to investigate the effect of 8 weeks of moderate-intensity continuous training (MICT) and high intensity interval training (HIIT) on the GLUT4 gene expression in skeletal muscle of obese male rats.
Materials and Methods: Twenty-eight male Wistar rats with 150 ± 25 grams body weight were divided into base control (n = 6), obese control (n = 6), MICT (n = 8), and (n = 8) HIIT groups as study sample. At the beginning of the study, base control group rats were sacrificed. In other groups, rats underwent high fat regime diet for 8 weeks. After one week of familiarization, rats in training groups run on treadmill for 8 weeks and 5 days per week. Forty-eight hours after the last session, the rats were scarified and gastrocnemius muscle tissue sample were removed. GLUT4 gene expression was measured by Real-Time PCR methods.
Findings: Results indicated that high fat diet for 8 weeks significantly increased rats body weight (p= 0.001), whereas both of MICT and HIIT training significantly decreased body weight (p= 0.001). Moreover, the MICT and HIIT had significant increase in GLUT4 gene expression in gastrocnemius muscle of obese rats (p = 0.001). Although, there were no differences between two experimental groups (p = 0.99).
Conclusion: According to the results, the MICT and HIIT increase gene expression of GLUT4 in mixed muscle fibers in obese rats.

Abstract

Background and Aim: Metabolic syndrome (MS) was committed multiple disorders including diabetes, hypertension, and obesity, which were played influential effects on the mortality rates of patients suffering from of cardiovascular disorders. Vascular endothelial growth factor (VEGF) is a protein that stimulates vascular and angiogenesis. One of the most common epigenetic changes is methylation of the promoter regions of genes, which leads to the regulation of gene expression. We aimed to assess the methylation pattern of promoter regions of VEGF gene which may act a critical role in the pathogenesis of MS.
Materials and Methods: In this descriptive-analytical investigation, we have assessed a total of 100 subjects, which were included 50 of cases diagnosed as MS and 50 healthy individuals as a control group. Methyl specific polymerase chain reaction (MS–PCR) method was performed to analyzing of VEGF gene promoter methylatin patterns and data analysis was performed using Chi Square test and SPSS 23 software.
Findings: The frequencies of VEGF gene promoter methylation observed in 32% and 20% of case and control individuals, respectively. Our findings revealed that the frequencies of the gene methylated were not statistically different between two groups (p=0.239). In other hand, our findings revealed a statistically significant difference regarding to the clinical parametrics including, triglycired (p=0.050), cholesterol (p=0.046), suger blood (p=0.025) and HbA1C (p=0.016) between cases and control groups (p=0.05).
Conclusion: According to our findings, methylation alteration in VEGF gene did not show any critical role in the pathogenesis of MS and it is suggested that more evidence will be needed to approve the present results.

Background and Aim: Working memory is a dynamic neural system for temporarily maintaining and processing of information. Prefrontal cortex (PFC) is the main processing center of Working memory by using different neurotransmitter systems communicate with other brain structures such as Basolateral Amygdala (BLA). In this study, we investigated the role of Opioidergic system in medial PFC and Dopaminergic system of BLA nucleus in working memory based on RAM test.
Materials and Methods: In this study, The male Wistar rats were used. Rats were cannulated with stereotaxic surgery in mPFC and BLA sites. After a recovery period, they were microinjected. Parameters such as working and reference memory errors were calculated with DSWS protocol.
Ethical Considerations: This study with research ethics code IR.UMZ.REC.1397.23 has been approved by Bioethics Committee at Mazandaran University, Iran.
Findings: High doses of Morphine (2 µg/rat) intra mPFC and Chloropromazine (2 µg/rat) intra BLA have improving effects on working and reference memory (p≤0.05). Low (0.005 µg/rat) and high dose (0.5 µg/rat) of Apomorphine had improving {(p≤0.05), (p≤0.01)} and the moderate dose (0.05 µg/rat) of it had decreasing effect on working and reference memory (p≤0.01). Microinjection of Morphine (0.5 µg/rat) with triple doses of Chloropromazine had no significant change on working and reference memory errors. Interaction of Morphine (0.5 µg/rat) with different doses of Apomorphine could change Apomorphine different effects. Coadministration of different doses of Apomorphine with effective dose of Chloropromazine (2 µg/rat) and Morphine (2 µg/rat) decreased the working and reference memory errors.
Conclusion: Our findings showed that in processing of working and reference memory, opioidergic system in mPFC and dopaminergic system in BLA, are interacting reciprocally.

Abstract

Background and Aim: Attention Deficit Hyperactivity Disorder is a common psychiatric disorder in children and paying attention to drugs that were used in this disorders are important. This study compares the efficacy of Ritalin with Memantin that is added to Ritalin on the severity of ADHD and attention deficit disorder in children.
Materials and Methods: This study is a clinical trial. All of 76 patients with diagnostic criteria for ADHD had been selected from the group of children that they were 7-12 years old, through diagnostic interviews in control & experimental groups based on DSM-V. At first, both groups filled out the Connors parent questionnaire for assessing the severity of the symptoms. Then, Ritalin was prescribed for the patients in the control group and Memantin was added to Ritalin for the patients in the experimental group for one month. The two groups again completed the questionnaire and the effectiveness of drugs was compared.
Ethical Considerations: This study with research ethics code 139510 has been approved by research ethics committee at Arak university of medical sceinces and also has been registered with code IRCT2016080829268N1 at Iranian Registry of Clinical Trials (IRCT).
Findings: According to the P-value of this test, there was no significant difference between the two groups after taking the drugs, which is equal to 0.324 and more than 0.05. But in that groups, there was a significant difference in severity of the symptoms between groups before and after taking the drugs.
Conclusion: Although the symptoms severity of hyperactivity decreased, there was no significant difference between these two groups. The Memantin added to Ritalin did not have a special effect on reducing the severity of symptoms compared to Ritalin. We can conclude the Ritalin might have had a significant effect on the symptoms reduction.

Abstract

Background and Aim: Lung cancer is one of the most contagious cancers in all of the world. Recently, several potential oncogenes and carcinogens have been identified, including EGFR, BRAF, KRAS and ALK genes. With due attention to the high prevalence of lung cancer, its death rate, the complications of chemotherapy and the efforts to find effective and less effective drugs, this study was done to investigate the effect of a plant extract so that results are available to manufacturing centers.
Materials and Methods: In this study, the effect of Eucalyptus extract and cisplatin on the expression of KRAS gene in A549 lung cancer cell line was investigated. To determine the cell survival, MTT was used and IC50 was determined. After determining IC50, the cells were exposed to less than IC50 concentrations of the extract and drug for 48 hours. Then, the amount of β-ACTIN and KRAS genes expressions in control and extract treated and drug treated groups were determined. For this purpose, a specific primers were designed for β- ACTIN and KRAS, and Real-Time PCR was be done.
Ethical Considerations: This study with research ethics code IR.IAU.East Tehran.REC.1396.3 has been approved by research ethics committee at Islamic Azad University, Tehran- East Branch, Iran.
Findings: The results showed that the amount of IC50 of the extract and drug was 8.75 and 1.77 mg/ml, respectively. In addition, the expression of genes in control and treated cells with extract and drug was compared. The expression of the KRAS gene relative to the reference gene in the cancer cell line treated with extract and drug, for 48 hours, was significantly decreased 2.89 and 9.25, respectively (p = 0).
Conclusion: Regarding the reduction of the relative gene expression in the A549 treated group, future studies on targeted lung cancer treatment can be promising and the potential for the use of plant compounds is more evident.

Abstract

Background and Aim: There is increasing evidence that cancer cells in addition to multiple genetic mutations, also acquire epigenetic abnormalities during development, maintenance, and progression. By utilizing the reprogramming technology as a tool to introduce the ‘pressure’ to alter epigenetic regulations, we might be able to clarify the epigenetic behavior that is unique to cancer cells. So far, iPSCs have been generated from normal primary cells, but it is unclear whether human primary cancer cell can be reprogrammed. We investigated the production of the iPS cells from the pancreatic adenocarcinoma cells using defined transcription factors.
Materials and Methods: We sought to reprogram patient derived xenograft from human PDAC, by introducing lentiviral mediated induction of Yamanaka Factors (OSKM) and characterized of induced cells by Alkaline Phosphatase staining, Real-Time PCR and immunostaining.
Ethical Considerations: This study with research ethics code EC/93/1025 has been approved by research ethics committee at Royan Institute.
Findings: Alkaline Phosphatase staining, Real-Time PCR and immunostaining showed that induction with the OSKM results in generating iPS cell line from fibroblast cells but not from PDAC PDX cells .We showed that, PDAC cells could not fully reprogrammed by the expression of 4 transcription factors.
Conclusion: This study demonstrated that the PDAC-PDX cancer cells were distinct from PDAC induced cells with regard to their epigenetic modifier genes expression pattern, although the expression of pluripotency genes did not increased significantly in the induced PDAC cells.
