Background: Usually, to produce radical sulfate, persulfate anions can be activated by heat, UV light and transition metals such as iron ions. The purpose of this study was investigation of performance of persulfate activated with iron produced by electrical method using iron anode electrode in degradation of Acid Blue 113 from aqueous solutions.
Materials and Methods: In this study, a lab-scale electrochemical batch reactor equipped with four iron electrodes and a DC power supply was used for removing of Acid Blue 113. The effect of operating parameters such as initial pH, voltage, persulfate and initial Acid Blue 113 concentration were evaluated. Also, the amount of pH changes during the process, the synergistic effect of processes in the system and Acid Blue 113 UV-Vis spectrum analysis in optimal conditions was investigated.
Results: The results showed, initial pH of solution, initial concentration persulfate and applied voltage has a significant effect on dye removal. Dye removal efficiency was higher in acidic condition and decreased with increasing pH, So that, after 2 min of reaction at pH 3, voltage 10 V and 150 mg/L of persulfate, 98% of the dye was removed, at pH 5, 7, 9 and 11, after 2 min of reaction and in the same condition the dye removal efficiency was, 66, 0, 0 and 13.5%, respectively. With increasing voltage from 1 to 10 V, increased the dye removal efficiency. S2O82- at the end of 20 min of reaction, removed 17% of dye, at the same condition, electrochemical process with iron electrode had only 31% efficiency, but, the combination of these two processes could remove 99.8% of dye.
Conclusion: The use of S2O82- anions in an electrochemical reactor with iron electrodes can be increase the efficiency of process. Therefore, using this process can be promising process to industrial wastewater treatment.

Background: The aim of this study is to assess of dose enhancement effect in tumour in presence of 10B, 157Gd, 10B nanoparticles and 157Gd nanoparticles in radiotherapy through neutron capture by Monte Carlo method.
Materials and Methods: A 252Cf brachytherapy source AT model was simulated by Monte Carlo method code MCNPX and its TG-43 parameters were calculated and compared with previous corresponding data. This 252Cf brachytherapy source was used as a neutron source in neutron capture therapy. Dose enhancement factor was compared in tumour in presence of 10B, 157Gd, 10B nanoparticles and 157Gd nanoparticles for the concentrations of 100, 200 and 500 ppm of each capture agents in neutron capture. For this aim, around the 252Cf source, a spherical soft tissue phantom and a tumour containing each capture agents were considered.
Results: Calculated air kerma strength and dose rate constant for 252Cf source equals to 0.306 cGycm2/hµg and 5.782 cGy/Uh respectively. Among examined agents, maximum DEF belonged to 10B and 10B nanoparticles in concentration of 500 ppm. These values were reported as 1.06 and 1.08 respectively.
Conclusion: IN this study, air kerma strength and dose rate constant indicate difference of %7.27 and %1.10 with other corresponding values. In dose enhancement point of view, capture agents containing 10B are more useful in neutron capture therapy. In the same concentrations, dose enhancement factor for capture agents in nanoparticles form is higher than the presence of capture agents in atomic form. So, it is preferable to use of nanoparticle capture agent rather than atomic form. However, it should be noted that before clinical usage of this agents, other medical, chemical and physical criteria should be considered, for their comparison, in selection of capture agents in neutron capture therapy.

Background and objective: Stress specially the chronic psychological one is an important issue of our modern society. In this regard, this study has been investigated the effects of chronic psychological stress on metabolic, hormonal and behavioral parameters.
Materials and methods: The present study is an experimental intervention.The animals were divided into control and stressed groups and then subdivided into 15 and 30 days (n=7). Stress was induced by the communication box.This device consisted of 9 chambers. The animals received electrical shock in five chambers and the animals in four chambers exposed to various emotional. Chronic stress for 15 and 30 days (h / day1) was applied. Blood sampling was done by using retro orbital puncture method. The plasma levels of glucose, cholesterol, triglyceride, insulin, and corticosterone were measured. In addition, feed and water intake, latency to eat and drink, adrenal and body weights were determined. For statistical analysis a mixed analysis of variance with repeated measures within the stressed and control groups and independent measures between the two groups was performed by SPSS Version 16.0 program package. The level of significance was considered less than 0.05.
Results: Chronic psychological stress did not significantly change plasma corticosterone (P=0.41), insulin (P=0.45), glucose (P=0.47), triglyceride (P=0.07) and cholesterol (P=0.26) levels. 30 days chronic stress significantly increased feed intake compared to control ones (P=0.01). Whereas water intake (P=0.07), latency to eat (P=0.70) and drink (P=0.08) did not change significantly in the stressed group. 30 days exposure to the stress in both control and stressed groups increased body (P=0.002 and P=0.004 respectively) and adrenal (P=0.01 and P=0.04 respectively) weights markedly compared to day 15.
Conclusion: short and mid-term psychological stress did not change hormonal and metabolic parameters significantly, whereas feed intake was significantly increased. However, no significant difference was observed in body weight of stressed animals compared to controls.

Background and Purpose: This study has been done with the aim of assessing the life quality (at subjective and objective levels), and social health and their relationship with each other in students of Islamic Azad University of Sabzevar, Iran.
Materials and Methods: The statistical population of the study included 4704 people which study in 15 majors from associate degrees to doctoral education. With the use of Morgan table, the sample size was calculated to be 380. By using a disproportionate stratified random sampling, statistical samples were selected from the statistical population, and the data were collected by two questionnaires of quality of life which are summary of two standard questionnaires for quality of life, the World Health Organization and Keynesian social health questionnaire; findings were analyzed with in SPSS with descriptive statistics and Pearson's correlation coefficient, Spearman, Mann Whitney U, and Kruskal Wallis.
Results: Although quality of life, in comparison to social health, has a better utility, students’ quality of life is not in a good condition. Their social health is assessed by dimensions of prosperity, participation and compliance (a little higher than average); reception and integration (lower than average and weak). Overall, there is no relationship between social health and quality of life in one hand, as well as grade, major, income, gender and academic achievement of students on the other hand.
Conclusion: One of the major causes of social health and quality of life is trust. Therefore, in order to increase social health among students, it is necessary to increase their trust of other members of society and social institutions by providing clear information through responsible institutions, preference of criteria to relations and the attention of authorities to their wishes and needs.

Background and purpose:Microsporidia infections occurvirtually in all in vertebrate and vertebrate hosts,in cluding humans. The this study is aimed atcomparison of distribution of microsporidiosis in various samples of Iranian immunocompromised patients and healthy individuals by molecular methods.
Materials and Methods: Inthiscase - control study, 258stool, blood, bronchoalveolar lavage (BAL) and urine sampleswere obtained fromimmunocompromisedpatients (bone marrowtransplant, kidney transplant and respiratory complications) referred to Masih Daneshvari and Shariati Hospitalduring 2010-2011.
After recording clinical data, DNA extraction was performed on all samples. To identifyhuman related microsporidiosis (Encephalitozoon spp. And Enterocytozoon spp.), polymerase chain reactionwas performedusingspecific primers andmultiplex-PCR on allsamples.
Results: Overall, the prevalence of microsporidiosis in immunocompromised patients were 4.3 and 3.9 percent in cases and control group, respectively.Incidence of microsporidiosis in patients undergoing bone marrow transplantation (5 isolates from 70 samples) was 7.1%, in patients with respiratory complications (4 isolates from 150 samples) 2.7 percent and patients undergoing renal transplantation (2 isolates from 38 samples) 5.3 percent. In the case group, most cases of infection occurred among men at the age of40-60 years. In bronchoalveolar lavage samples 3 isolates of Encephalitozoon (2%) and one isolate of Entrocytozoon (0.7%), were identified, respectively. In cancer patients undergoing bone marrow transplantation 4 isolates of Encephalitozoon (5.7%), 1 isolate of Enterocytozoon (1.4%) and in patients with renal transplants 2 isolates of Enterocytozoon (5.3%)were detected. 4 isolates of Enterocytozoon (2.2%) and 3 isolates of Encephalitozoon (1.7%) were identified in the control group that most infections occurred among menat the age of30-45years.
Conclusion:The most cases of human microsporidiosis are associated with human immunodeficiency virus infection or other states of immunosuppression, particularly in organ transplant recipients; The obtained results confirm this claim.

Background and Purpose: Evaluation of puberty stages is important to assess adolescent health. This study has been done with the aim of determination of the average age of onset of puberty and its relationship with Body Mass Index (BMI) in male students of Sabzevar city in the North East of Iran in 1390.
Methods and Materials: This cross - sectional study was conducted on 252 male students of secondary schools and high schools of Sabzevar, Iran, with the age of 11-18 years who were selected by probability and multistage sampling. Data were collected through a Tanner standardized questionnaire; afterwards, measuring of height and weight and BMI calculation were performed. Data were analyzed in SPSS 15 using chi-square test, t-test, ANOVA and Bonfronie post hoc test, analysis of covariance, Spearman correlation coefficient and Kappa agreement coefficient; significance level was considered as 0.05.
Results: To conduct this study, we selected a group of researchers who were trained for the initiation of project for assessing puberty in male schools in order to increase the accuracy of determining the Tanner stages. Students were examined for their height and weight, size of penis and testicles, and the manner of pubic and axillary hair growth as well as also voice changes. Mean final growth stage of testicles and scrotum (G5 stage), pubic hair (P5 stage), were measured to be 16.40 ± 1.65 and 16.79 ± 1.19 years respectively, and their mean BMI at P2 and G2 were 20.96±4.1 and 19.49±3.66 kg /m2 respectively.
Conclusion: Regarding to the declining age of puberty and its relationship with BMI, health systems should focus on training programs and encouraging teenagers to begin changing their lifestyle. Age of puberty onset in male students is similar to many other countries but determining the precise status of puberty in Iranian children requires further studies in different provinces, rural and urban areas as well as longitudinal studies.

Background and purpose: Athletes try toimprove their performance by using different techniques. Using supplements is one of these methods. Creatine supplement is one of the most popular body building supplements and its usage has been increased dramatically in recent years. Unfortunately our knowledge of the effects of this supplement on body isn't enough. Therefore, this study was aimed at evaluating the effects of short-term use of Creatine supplement on urinary excretion of Creatine and Creatinine and anaerobic performance among bodybuilding athletes.
Materials and Methods: Sixteen male bodybuilders (23.8±3.4years old) were assigned in a double-blind clinical trial and were randomly divided into two groups, a Creatine treatment group or aplacebo group. Creatine and Creatinine concentrations inurine were determined for both groups before and after intervention and anaerobic performance was evaluated by the Wingateanaerobic test method.
Results: The results revealed an increase in of urinary Creatine and Creatinine concentration sin the Creatine recipient group. Also three measured indices of the Wingate test, including peak power, average power and fatigue index increased in the Creatine recipient group.
Conclusion: According to the increase in anaerobic performance indices among subjects, Creatine supplement can improve body builders performances. According to obtained increase in urinary Creatine and Creatinine concentrations, evaluation of probable side effects of long termuse of this supplement, especially on renal function is necessary.

Background: This laboratory experiment was aimed of to investigate the antibacterial effect of Polypropylenimine-G2 (PPI-G2) and Polyamidoamine-G4 (PAMAM-G4) dendrimers on Klebsiella oxytoca, Pseudomonas aeruginosa and Proteus mirabilis.
Materials and Methods: Different concentrations of PPI-G2 and PAMAM-G4 dendrimers were inoculated onto Blank disks and were placed in Mueller-Hinton agar media. Zone of inhibition was investigated by bacterial inoculation according to the McFarland standard 0.5. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of PPI-G2 and PAMAM-G4 dendrimers were determined by Micro-dilution method in nutrient broth culture.
Results: Zone of inhibition in concentration 500 μg/ml of PPI-G2 dendrimers for Klebsiella oxytoca, Proteus mirabilis and Pseudomonas aeruginosa were 25, 15 and 20mm, respectively. Zone of inhibition in concentration 500 μg/ml of PAMAM-G4 dendrimers for Klebsiella oxytoca, Proteus mirabilis and Pseudomonas aeruginosa were 20, 18 and 0mm, respectively. The MIC of PPI-G2 dendrimer for Klebsiella oxytoca and for Pseudomonas aeruginosa were 5 μg/ml. Also, the MIC of PPI-G2 dendrimer for Proteus mirabilis was 50 μg/ml. The MBC of PPI-G2 dendrimer for Klebsiella oxytoca was 50 μg/ml and it was 500 μg/ml for Proteus mirabilis and Pseudomonas aeruginosa. The MIC of PAMAM-G4 dendrimer attributed to Klebsiella oxytoca and Proteus mirabilis were reported 500 and 1250 μg/ml, respectively. The MBC of PAMAM-G4 dendrimer belonged to Klebsiella oxytoca and Proteus mirabilis were 1250 and 2500 μg/ml, respectively.
Conclusion: According to the results, PPI-G2 dendrimers can eliminate Pseudomonas aeruginosa, Klebsiella oxytoca and Proteus mirabilis effectively but PAMAM-G4 only has antibacterial effect against Klebsiella oxytoca and Proteus mirabilis. Also the antibacterial activity of PPI-G2 dendrimer is obviously better than those of PAMAM-G4. However, using dendrimers can be considered as a new approach for drinking water disinfection but it requires further wide range studies.

Background: In recent years, crisis of water shortage has become a serious problem in many countries. In this regard, the use of treated wastewater in natural or artificial method in agriculture and the like, has been proposed as an important and practical solution. The natural purification method by the use of artificial canebrakes, compared with other methods of treatment is an appropriate method because of its low cost, and also, because of easy navigation, the requirements of low technology and low energy consumption. Several herbs have been used to increase the efficiency canebrakes which including special plants to purify such wastewater is Vetiveria that has unique genetic, morphological and physiological characteristics. Due to the limited knowledge of the plant's industrial wastewater treatment, in this study, a comparison of filterablity of hospital wastewater was done between Vetivaria and bulrush in tropical areas.
Methods: This experimental study was done in 2013 in the hot season, summer. In this study, was made two pilot glass with dimensions of 50*60*100 Cm. A mixture of soil, sand, gravel, clay soil was selected. The irrigation method in this study was subsurface and continuous. First, hospital wastewater via a 220 liter tank as the primary sedimentation retention time and with time of 2 hours entered into bed with a hydraulic retention time of 4 days to discharge 85/0 liters per hour. To evaluate the efficiency of each plant in the treatment of hospital wastewater, chemical parameters including (PH, TP, TN , TSS, BOD5, COD)were measured according to standard methods of measuring. . Analysis of the data was done by the use of t-test and Mann-Whitney and SPSS software.
Results :Based on the finding of this study, percentage of removal parameter(Bod5,Tss,Tn,Tp) by plant Vetiveria was (88.54,95.71,93.93,99.80) and for bulrush was (82.54,91.13,86.64,99.28).
Conclusion: Due to the unique characteristics of Vetiveria, such as high resistance against unfavorable environmental conditions and its higher efficiency than bulrush, this plant is recommended for the treatment of hospital wastewater.

Background and Purpose: Traditional baker’s occupation is a complex of long repetitive tasks and movements with high intensity which exposes the baker into musculoskeletal disorders. The aim of this study was a detailed analysis of risk factors leading to the incidence of musculoskeletal disorders in Sabzevar bakers.
Materials and Methods: This cross-sectional descriptive study was conducted on 70 traditional bakers in Sabzevar, Iran who were selected by simple random sampling. First, the prevalence of musculoskeletal disorders was determined using Nordic Musculoskeletal Questionnaire; then, Rapid Upper Lumbar assessment (RULA) was used for assessing postures to obtain final scores. Data were analyzed using R software (version R2.15.2).
Results: Based on the findings, the average age and work experience of bakers were 19.4 and 36.4 years respectively. The most symptomatic risk factors were related to shoulder (%56.8) and knees (50%). In assessing Rapid Upper Lumbar assessment (RULA), 33.34% of personnel (correction level 4) obtained 7, and 55% obtained 5 and 6 (with Corrective level 3). Non-parametric showed significant correlation between the musculoskeletal disorders and age (p = 0.02) and work experience (p = 0.03) (confidence level 95%). In other words, bakers with older age and more work experience suffered from more disorders
Conclusion: Based on the results, a significant percentage of traditional bakers work in an ergonomically unsafe environment (%88.3), and the frequency of musculoskeletal disorders is high in this population; this requires urgent ergonomic and managerial action.

Background and purpose: Nowadays repeated transcranial magnetic stimulation (rTMS) is being used as a treatment for some neurological disorders, but its effect on neuronal activity and synaptic plasticity has not been completely determined. The purpose of this study was to evaluate the effect of chronic rTMS on the ability of synaptic plasticity.
Materials and Methods: rTMS was applied to the hippocampal region for 14 days. One week following termination of rTMS, the amount of synaptic long-term potentiation (LTP) in animals was investigated and compared with control group. High-frequency stimulation (HFS) was applied to the perforant path for LTP induction, andfield potentials were recorded from granular layer of the dentate gyrus. Baseline field potential was recorded 10 minutes before HFS. An increase of at least 20% in population spike amplitude was measured as an index of synaptic potentiation.To compare the effects of rTMS on measured parameters, we used t-test and two way ANOVA followed by Benferroni test (Prism 8 software).
Results: Obtained data showed that, following 14 days of rTMS application causeda reduction in population spike amplitude compared to the control group (P
