Abstract
Background: Few studies have investigated the possible ways to prevent lead induced defects during gestation and lactation. The aim of this study was to investigate the effect of melatonin as a hormone with antioxidant properties on oxidative stress in the hippocampus and learning and memory impairment induced by administration of lead.
Materials and Methods: Pregnant rats were exposed to treatments of control, lead acetate (0.2% solution in water), lead acetate + melatonin and melatonin (10 mg / kg by oral gavage) from gestation day 6 until weaning. 21 days after birth, the activities of several antioxidant enzymes including superoxide dismutase (SOD), glutathione peroxidase (GPX) and catalase (CAT) as well as malondialdehyde levels in hippocampus of 23 male offspring rats were assayed. To behavioral studies, on postnatal day 30, 57 rats were trained 6 days in the Morris water maze and the probe test was performed 24 h later.
Results: The results showed that administration of lead during pregnancy and lactation could increase MDA levels and decrease glutathione peroxidase, superoxide dismutase and catalase antioxidant enzymes activities in the hippocampus of male offspring. Also, this treatment significantly disrupted performance of the Morris water maze test and impaired learning and spatial memory in male offspring compared with control. Administration of melatonin attenuated lipid peroxidation and could improve learning and spatial memory deficits and the activity of antioxidant enzymes in lead exposure group.
Conclusion: Melatonin as a neuropotective drug can protect the hippocampus against the complications of lead exposure, in the course of development.

Abstract
Background: Migraine is a chronic neurological disorder that leads patients to avoid any kind of activities. Since different factors are involved in migraine incidence and its triggers, so drugs are used to prevent or treat it are so variable. Also, combined medications are used to relieve migraine. This study examined the effectiveness of self-control training on quality of life in patients with migraine.
Materials and Methods: Statistic population of this study included all migraine patients in Ardabil in 2014(Estimation: N=1150) that 40 patients were selected by convenience sampling. Demographic and disease information questionnaire and quality of life questionnaire (SF-36) were used to collect data in clinical centers. Multivariate analysis of variance (MANCOVA) was used to analyze data, because present research was a experimental and clinical trial with pre-test and post-test with control group.
Results: The results showed that there is a significant difference between mean in quality of life in migraine patients and control subjects. It means that physical health and mental health of quality of life was different between control and experimental groups after self- control training.
Conclusion: Self-control training can be used to enhance quality of life in migraine patients. These results have important and effective applications in the treatment of migraine patients. Generally, specialists of clinical centers can use this method alongside other treatment interventions.

Abstract
Background: In present research, the structural equation modeling of the relationship between cognitive avoidance and rumination with clinical symptoms of OCD with mediating role of cognitive failure was studied.
Materials and Methods: In a descriptive correlational study, 220 patients with OCD were selected from Urmia psychological clinics and completed YBOCS, RRS, CAQ, and CFQ questionnaires. For data analysis, structural equation modeling (SEM) was used.
Results: The results showed that the modified final model is best fitted with present research data and cognitive avoidance, rumination, and cognitive failure paths with OCD and cognitive avoidance, and rumination paths with cognitive failure were significant. Also, indirect paths such as cognitive avoidance and rumination to OCD were significant.
Conclusion: According to the results of this study, it can be concluded that in addition to the direct relationship, cognitive failure can adjust the relationship between cognitive avoidance and rumination with OCD.

Abstract
Background and Aim: Enterococci are among the microbial flora in human and animals digestive tract. The nosocomial pathogenicity of enterococci has emerged in recent years. The purpose of the study was to evaluate the effect of a diode laser with a wavelength of 810nm and a power of 30mw at 180s on the survival of an antibiotic resistant enterococci.
Materials and Methods: 30 clinical isolates of enterococcus bacteria were tested for sensitivity to antibiotics according to diffusion method. 10 isolates with the highest antibiotic resistance were selected and diode laser with a wavelength of 810nm and a power of 30mw for 180s were beamed on them and investigated.
Findings: The Results of our antibiotic susceptibility test showed that among 30 isolates resistant to antibiotic enterococci, 27 isolates (90%) were resistant to Oxacillin antibiotics. The results of the diode laser radiation showed that the lowest survival rate of the intended isolates was at 810nm and 30mw for 180s (0.58%).
Conclusion: Based on the results obtained, the antibacterial effect of the diode laser is at 810nm and 30mw for 180s. Therefore, it is recommended to use a 810nm diode laser to eliminate clinical strains of antibiotic-resistant enterococci.

Abstract
Background and Aim: Background and Aim: Photodynamic therapy is a minimally invasive approach to cancer, which is used to combine non-toxic photosensitizer and visible light to produce reactive oxygen species and destroy tumors. This study aimed to investigate the cytotoxicity effect of Graphene Oxide (GO)as an organic matter with many oxygen groups on photodynamic on destroying cancer cells.
Materials and Methods: This study was performed on breast cancer cells (MCF-7) in vitro. The study groups included the first group of drug with different concentrations of graphene oxide (333.3, 285.7, 230.7, 166.6, 90.9,
47.6 µg/ml), the second group co-drug and laser light irradiation and the control group consisted of cells treated only with laser irradiation and the control group was treated with no treatment. Cells were exposed to visible laser irradiation (405 nm) at 0.1 W / cm2. Cell viability was determined by MTT assay.
Ethical Considerations: This study with research ethics code SBU/S.1397.46A has been approved by research ethics committee at Shahid Behesht University of Tehran, Iran.
Findings: The results of in vitro experiments showed that the dark toxicity of graphene oxide at concentrations of less than the 90.9 μg / ml concentration had no significant effect on cancer cells. Also, laser light alone don’t has toxic effect on cells. But graphene oxide-mediated dynamic light therapy has reduced the bioavailability of cancer cells on average by 21% over dark toxicity. Results are presented as mean of three independent replications, standard error, and p< 0.05 was considered significant.
Conclusion: In this study, graphene oxide is fully biodegradable at concentrations below a certain value, but with increasing concentration, the toxicity effect increases. With exposure to light and graphene oxide, viability decreses that it is more effective for in vivio studies.

Abstract
Background and Aim: Genetic and environmental factors are known to be related to the development of childhood Eczema. We aimed to assess the ecological factors associated with the prevalence of Eczema among children using the ISAAC questionnaire.
Methods & Materials: A total of 1600 primary school girls and boys were selected and examined by multistage random sampling in this cross-sectional study. Data were collected and completed using the International ISAAC Questionnaire, including demographic questions and risk factors through interviews with parents, especially the student’s mother. The data were analyzed in SPSS v. 19 software using the Chi-square test and multiple logistic regression.
Ethical Considerations: This study was approved by the Ethics Committee of Zahedan University of Medical Sciences (Code: REC.1397.481).
Results: The prevalence of current Eczema was 10.4% (95%CI: 8.9-11.9). Co-morbidity with Asthma and Rhinitis was 82.8% and 74.5%, respectively. In multiple logistic regression models, history of allergies in family members (OR: 2.35, 95%CI: 1.53-3.59), father snoring (OR: 3.00, CI95%: 1.98-4.55), Keeping any animal in (OR: 1.6, 95%CI: 1.002-2.58), family size (OR: 0.85, 95%CI: 0.68-0.95), exposure to tobacco smoke at home (OR: 2.84, 95%CI: 1.18-6.81), showed a significant relationship with the occurrence of students’ Eczema.
Conclusion: Exposure to tobacco smoke at home, keeping any animal at home are effective factors in the prevalence of Eczema in children. By eliminating these factors, the prevalence of this disease can be reduced. However, the mothers have the most crucial role in screening and early diagnosis of Eczema in school children regarding determinants in this study. According to the results of this study, it is suggested that parents’ education, especially mothers, be emphasized by paying attention to these favorable factors.

Abstract
Background and Aim Recently, a myokine called irisin has been discovered that affects glucose level, obesity, metabolism and glucose homeostasis by browning of white adipose tissue and heat production. This study aims to evaluate the effect of four weeks of ginger supplementation followed by acute eccentric and concentric training on irisin and insulin levels, insulin resistance index, and lipid profile of young women with obesity.
Methods & Materials This is a randomized clinical trial. Participants were 50 young women (BMI >30 kg/m2, age: 24.86±2.87 years, height: 159.66±4.20 cm, and weight: 87.42±4.61 kg). After measuring their maximum oxygen consumption, they were randomly divided into five groups, two groups of supplementation, two groups of placebo, and one control group. The training protocol consisted of two sessions of acute eccentric and concentric activity. The supplementation groups consumed 2 g of ginger powder daily for 4 weeks. Blood samples were collected before and immediately after each activity. Data were analyzed using dependent t-test and one-way analysis of variance (ANOVA).
Ethical Considerations This study was registered by Iranian Registry of Clinical Trials (Code: IRCT201104246178N1) and was approved by the ethics committee of Ilam University of Medical Sciences (Code: IR.MEDILAM.REC.1395.192).
Results The irisin and insulin levels between increased and the glucose level decreased significantly in the supplementation groups (P<0.05). The change in insulin resistance index was not significantly different among the study groups (P>0.05). Based on the results of one-way ANOVA, triglyceride and low-density lipoprotein levels decreased significantly (P<0.05), but the high-density lipoprotein level showed no significant difference (P<0.05). The total cholesterol level was not significantly different in terms of exercise type (P> 0.05) but was significantly different in terms of supplementation type (P<0.05).
Conclusion Long-term consumption of ginger along with regular exercise can be an effective method for lowering glucose level and causing favorable changes in irisin level, insulin resistance, and lipid profile in young women with obesity.
