Abstract
Epilepsy is a neurological condition distinguished by recurrent and unexpected seizures. Astrocytic channels and transporters are essential for maintaining normal neuronal functionality. The astrocytic water channel, aquaporin-4 (AQP4), which plays a pivotal role in regulating water homeostasis, is a potential target for epileptogenesis. In present study, we examined the effect of different doses (10, 50, 100 μM and 5 mM) of AQP4 inhibitor, 2-nicotinamide-1, 3, 4-thiadiazole (TGN-020), during kindling acquisition, on seizure parameters and seizure-induced cognitive impairments. Animals were kindled by injection of pentylenetetrazole (PTZ: 37.5 mg/kg, i.p.). TGN-020 was administered into the right lateral cerebral ventricle 30 min before PTZ every alternate day. Seizure parameters were assessed 20 min after PTZ administration. One day following the last PTZ injection, memory performance was investigated using spontaneous alternation in Y-maze and novel object recognition (NOR) tests. The inhibition of AQP4 during the kindling process significantly decreased the maximal seizure stage and seizure duration (two-way ANOVA, P = 0.0001) and increased the latency of seizure onset and the number of PTZ injections required to induce different seizure stages (one-way ANOVA, P = 0.0001). Compared to kindled rats, the results of the NOR tests showed that AQP4 inhibition during PTZ-kindling prevented recognition memory impairment. Based on these results, AQP4 could be involved in seizure development and seizure-induced cognitive impairment. More investigation is required to fully understand the complex interactions between seizure activity, water homeostasis, and cognitive dysfunction, which may help identify potential therapeutic targets for these conditions.

Abstract
PURPOSE This study aims to assess the vision-related quality of life in patients with retinal vein occlusion (RVO) among those referred to Labbafinejad Medical Center and Imam Hossein Hospital between 2019 and 2021. METHODS This comparative study included 37 eligible patients diagnosed with various types of RVO, with an average age of 61 ± 9. To ensure data validity, we included 74 age- and sex-matched healthy individuals. Only cases with a definitive diagnosis of RVO, confirmed by two retina specialists (ND and RN), were included. We assessed the vision-related quality of life of our participants using the National Eye Institute Visual Functioning Questionnaire-25 (NEI-VFQ-25). All participants underwent interviews. RESULTS In our study, we examined the vision-related quality of life in different subgroups of RVO patients. Overall, RVO patients had a significantly lower total VRQoL score compared to healthy individuals (P < 0.001), except in the subscale analysis of specific factors such as ocular pain, color vision, and driving, where no statistically significant difference was observed. A statistically significant difference was found in the comparison of subgroups, indicating lower VRQoL in central retinal vein occlusion (CRVO) patients (P = 0.010). Furthermore, a significant correlation was observed between lower VRQoL and decreased vision (P = 0.009) as well as longer disease duration (P = 0.011). CONCLUSION Retinal vein occlusion can significantly reduce vision-related quality of life, particularly in more severe cases.

Abstract
The present study aimed to investigate the effect of corticolimbic cannabinoid CB1 receptors activity on memory impairment in the intracerebroventricular (ICV)-streptozotocin (STZ) animal model of Alzheimer's like-disease. This study also assessed whether the corticolimbic overexpression of miRNA-137 or -let-7a could increase the endocannabinoids by inhibiting the monoglyceride lipase (MAGL) to ameliorate STZ response. The results showed that ICV microinjection of STZ (3 mg/kg/10 μl) impaired passive avoidance memory retrieval. The chronic microinjection of arachidonylcyclopropylamide (ACPA; 10 ng/0.5 μl), a selective cannabinoid CB1 receptor agonist, into the hippocampal CA1 region, the central amygdala (CeA) or the medial prefrontal cortex (mPFC) ameliorated the amnesic effect of ICV-STZ. Intra-CA1 or -CeA microinjection of ACPA alone did not affect memory retrieval, while its microinjection into the mPFC impaired memory formation. Based on bioinformatics analysis and verification of the MAGL gene, miRNA-137 and -let-7a were chosen to target the expression levels of MAGL in the corticolimbic regions. The chronic corticolimbic microinjection of lentiviral particles containing miRNA-137 or -let-7a ameliorated ICV-STZ-induced memory impairment. The high transfection efficiency was determined for each virus using comparing fluorescent and conventional vision. Corticolimbic overexpression of miRNA-137 or -let-7a decreased the MAGL gene expression that encodes the MAGL enzyme to increase the endocannabinoids. Thus, among the molecular mechanisms and signaling pathways involved in the pathophysiology of Alzheimer's disease (AD), it is worth mentioning the role of endocannabinoids in the corticolimbic regions. CB1 receptor agonists, miRNA-137 or -let-7a, may be potential therapeutic targets against cognitive decline in AD.

Abstract
AIMS Heart failure (HF) after myocardial infarction (MI) is a major cause of morbidity and mortality. We sought to investigate the functional importance of cardiac iron status after MI and the potential of pre-emptive iron supplementation in preventing cardiac iron deficiency (ID) and attenuating left ventricular (LV) remodelling. METHODS AND RESULTS MI was induced in C57BL/6J male mice by left anterior descending coronary artery ligation. Cardiac iron status in the non-infarcted LV myocardium was dynamically regulated after MI: non-haem iron and ferritin increased at 4 weeks but decreased at 24 weeks after MI. Cardiac ID at 24 weeks was associated with reduced expression of iron-dependent electron transport chain (ETC) Complex I compared with sham-operated mice. Hepcidin expression in the non-infarcted LV myocardium was elevated at 4 weeks and suppressed at 24 weeks. Hepcidin suppression at 24 weeks was accompanied by more abundant expression of membrane-localized ferroportin, the iron exporter, in the non-infarcted LV myocardium. Notably, similarly dysregulated iron homeostasis was observed in LV myocardium from failing human hearts, which displayed lower iron content, reduced hepcidin expression, and increased membrane-bound ferroportin. Injecting ferric carboxymaltose (15 µg/g body weight) intravenously at 12, 16, and 20 weeks after MI preserved cardiac iron content and attenuated LV remodelling and dysfunction at 24 weeks compared with saline-injected mice. CONCLUSION We demonstrate, for the first time, that dynamic changes in cardiac iron status after MI are associated with local hepcidin suppression, leading to cardiac ID long term after MI. Pre-emptive iron supplementation maintained cardiac iron content and attenuated adverse remodelling after MI. Our results identify the spontaneous development of cardiac ID as a novel disease mechanism and therapeutic target in post-infarction LV remodelling and HF.

Abstract
BACKGROUND Glioblastoma multiforme (GBM) is associated with remarkably poor prognosis, and its treatment is challenging. This investigation aimed to evaluate the safety of suicide gene therapy using allogeneic adipose tissue-derived mesenchymal stem cells (ADSCs) carrying herpes simplex virus-thymidine kinase (HSV-TK) gene for the first time in patients with recurrent GBM. METHODS This study was a first-in-human, open-label, single-arm, phase I clinical trial with a classic 3 + 3 dose escalation design. Patients who did not undergo surgery for their recurrence were included and received this gene therapy protocol. Patients received the intratumoral stereotactic injection of ADSCs according to the assigned dose followed by prodrug administration for 14 days. The first dosing cohort (n = 3) received 2.5 × 105 ADSCs; the second dosing cohort (n = 3) received 5 × 105 ADSCs; the third dosing cohort (n = 6) received 10 × 105 ADSCs. The primary outcome measure was the safety profile of the intervention. RESULTS A total of 12 patients with recurrent GBM were recruited. The median follow-up was 16 (IQR, 14-18.5) months. This gene therapy protocol was safe and well tolerated. During the study period, eleven (91.7%) patients showed tumor progression, and nine (75.0%) died. The median overall survival (OS) was 16.0 months (95% CI 14.3-17.7) and the median progression-free survival (PFS) was 11.0 months (95% CI 8.3-13.7). A total of 8 and 4 patients showed partial response and stable disease, respectively. Moreover, significant changes were observed in volumetric analysis, peripheral blood cell counts, and cytokine profile. CONCLUSIONS The present clinical trial, for the first time, showed that suicide gene therapy using allogeneic ADSCs carrying the HSV-TK gene is safe in patients with recurrent GBM. Future phase II/III clinical trials with multiple arms are warranted to validate our findings and further investigate the efficacy of this protocol compared with standard therapy alone.

Abstract
1. This experiment investigated the efficacy of varying doses of an emulsifier blend (EB; 0 and 1 g/kg of diet), betaine (BT; 0 and 1 g/kg of diet) and L-carnitine (CT; 0 and 0.5 g/kg of diet) in broilers subjected to circular heat stress (HS) conditions. A total of 1080 one-day-old male broiler chickens (Ross 308) were randomly assigned to one of nine treatment groups (six pens/treatment with 20 birds/pen) according to a completely randomised design. The thermoneutral control broiler chickens were housed at a comfortable temperature and fed a standard diet (no additives). The other eight groups were exposed to cyclic HS conditions (34°C) for 8 h (10:00-18:00).2. There were EB × BT × CT interactions for body weight (BW) at 24 d (P = 0.038) and average daily gain (ADG) during the 10-24 d period (P = 0.049), with the greatest values found with concurrent supplementation of three supplements.3. Inclusion of EB resulted in greater (P < 0.05) BW, ADG, European performance index, uniformity rate, primary antibody titres against sheep red blood cells (SRBC), duodenal villus height (VH) and villus surface area, digestible energy (DE) and the coefficient of apparent ileal digestibility (CAID) of dry matter, crude protein, and fat However, feed conversion ratio, mortality rate and heterophile to lymphocyte ratio were lower (P < 0.05).4. Dietary BT supplementation improved (P < 0.05) all performance indicators, primary antibody titres against SRBC and Newcastle disease virus, serum total antioxidant capacity, duodenal VH, Jejunal VH/crypt depth and the CAID of dry matter and crude protein. The effect of dietary supplementation with CT was limited to an increase (P < 0.05) in ADG (d 10-24) and a decrease (P < 0.05) in serum malondialdehyde concentration (42 d) and jejunal crypt depth (42 d).5. In conclusion, dietary supplementation of either EB or BT alone or in combination ameliorated some of the detrimental effects of HS on growth performance, immunity and intestinal health in broilers, while a minor positive effect on performance and antioxidant status was observed with CT supplementation.

Abstract
Introduction The prognosis for glioblastoma multiforme (GBM), a malignant brain tumor, is poor despite recent advancements in treatments. Suicide gene therapy is a therapeutic strategy for cancer that requires a gene to encode a prodrug-activating enzyme which is then transduced into a vector, such as mesenchymal stem cells (MSCs). The vector is then injected into the tumor tissue and exerts its antitumor effects. Case presentation A 37-year-old man presented to our department with two evident foci of glioblastoma multiforme at the left frontal and left parietal lobes. The patient received an injection of bone marrow-derived MSCs delivering the herpes simplex virus thymidine kinase (HSV-tk) gene to the frontal focus of the tumor, followed by ganciclovir administration as a prodrug for 14 days. For follow-up, the patient was periodically assessed using magnetic resonance imaging (MRI). The growth and recurrence patterns of the foci were assessed. After the injection on 09 February 2019, the patient's follow-up appointment on 19 December 2019 MRI revealed a recurrence of parietal focus. However, the frontal focus had a slight and unremarkable enhancement. On the last follow-up (18 March 2020), the left frontal focus had no prominent recurrence; however, the size of the left parietal focus increased and extended to the contralateral hemisphere through the corpus callosum. Eventually, the patient passed away on 16 July 2020 (progression-free survival (PFS) = 293 days, overall survival (OS) = 513 days). Conclusion The gliomatous focus (frontal) treated with bone marrow-derived MSCs carrying the HSV-TK gene had a different pattern of growth and recurrence compared with the non-treated one (parietal).

Abstract
Objective: The aim of this study was to investigate the moderating role of job control in relation to mental workload and job satisfaction of healthcare workers. Methods: This cross-sectional study was carried out on 480 nurses, midwives, and administrative workers in four educational hospitals of Ardabil, Iran. Research tools were included demographic information questionnaire, NASA-TLX questionnaire, job description index (JDI) questionnaire and job control inquiry. Results: Compared with administrative workers, mental workload of nurses and midwives was significantly higher and likewise mental workload of nurses was significantly difference compared to midwives (P < 0.001). Nurses and midwives had substantially higher job satisfaction than administrative workers (P < 0.001). Also, nurses and midwives had higher job control than administrative workers (P < 0.001 and P = 0.002, respectively). Based on the designed model, the correlation between mental workload and job satisfaction was negative and significant (r = -0.22); which in the presence of job control, the relationship between the two variables of workload and job satisfaction slightly increased (r = -0.19, P < 0.001). These conditions were the same in the three job groups separately. Conclusion: Mental workload is inversely related to job satisfaction and job control. Job control plays an important role in improving working conditions in healthcare workers.

Abstract
Nanotechnology has enabled the preparation of various materials for overcoming the rapid clearance of drugs, nonspecific uptake or actions, and poor tumor penetration. Based on the significance of using biomimetic substances, silk fibroin nanoparticles (SF-NPs) have been increasingly prepared for the delivery of therapeutics. Meanwhile, aggregation and low stability in the biological medium may negatively affect their efficiency. This prompted us to coat SF-NPs with polydopamine (PDA), and for efficient accumulation and increasing therapeutic efficiency against breast cancer, paclitaxel (PTX)-loaded PDA-coated SF-NPs were conjugated with targeting peptide, iRGD (iRGD-PDA-PTX-SF-NPs). The peptide impacts on the cellular uptake, cytotoxicity, tumor penetrability of NPs, and their antitumor effects were evaluated. iRGD-PDA-PTX-SF-NPs with suitable physicochemical characteristics and drug loading released PTX in a controlled manner, and efficient cellular uptake was observed. Improved pharmacological profile of PTX was revealed by increased anticancer effects in vitro and in tumor-bearing Balb/c mice, including the delayed growth of the tumor and enhanced rate of survival. The prepared NPs showed no toxic effects against the healthy tissues indicating the histocompatibility and safety of these biomimetic and long-circulating nanoplatforms. The peptide-based SF-NPs could be considered as promising biomimetic nanoformulation against breast cancer.

Abstract
Breast cancer therapy has remained one of the major healthcare challenges. Based on the critical role of cyclin-dependent kinase 4/6 (CDK 4/6) in cell cycle progression, targeting this signaling appears promising for cancer therapy. Palbociclib, a selective CDKs 4/6 inhibitor, is the first-line treatment for estrogen receptor-positive breast cancer. However, poor absorption or side effects may negatively affect its efficiency. This prompted us to incorporate palbociclib into the nanostructured lipid carriers (NLCs) and evaluate the anticancer effect of the nanoformulation (Pa-NLCs) in in vitro and in vivo models of breast cancer. Pa-NLCs were developed by high-pressure homogenization followed by assessment of the physicochemical characteristics and bioactivities in MCF-7 breast cancer cells and female Wistar rats exposed to the carcinogen 7,12-dimethylbenz(a)anthracene (DMBA). The prepared Pa-NLCs demonstrated suitable physicochemical characteristics, including the controlled release pattern, efficient cellular uptake, and cytotoxicity, while free palbociclib failed to show significant effects. Rats treated with Pa-NLCs exhibited significantly reduced tumor volumes, increased survival rates, and histopathological improvement. Free palbociclib was significantly less efficient than Pa-NLCs. Pa-NLCs, by improving the pharmacological profile of palbociclib and providing longer-lasting effects, can be considered as a promising nanoformulation against breast cancer.

Abstract
Colorectal cancer (CRC) with high metastasis rates has been known as a major cause of death worldwide. Lack of the specificity and insufficient concentrations of traditional chemotherapeutics at tumor site and their severe adverse effects necessitate development of new treatment strategies such as designing suitable nanocarriers for delivery of drugs, improving their pharmacological profiles and reducing adverse effects. We have developed a platform based on the poly-ursolic acid (poly-UA), a polymeric system with potential anticancer effect. Following the self-assembly of poly-UA into the nanoparticles (NPs), they were applied for delivery of mithramycin A (Mith-A), a promising candidate for CRC therapy, however, with some limitations such as rapid clearance and serious side effects. Mith-A-loaded poly-UA NPs with suitable physicochemical properties and efficient drug entrapment, released Mith-A in a controlled manner and provided suitable toxicity against the CT-26 colorectal cancer cells, increased accumulation in tumor, and protection against the detrimental features of the disease. Poly-UA NPs demonstrated therapeutic efficiency (in vivo and in vitro) by themselves. The prepared NPs induced no remarkable alteration of body weights or damages to the major organs in animals bearing tumor indicating the safety of NPs. The bioactive nanoformulation along with improving the pharmacological profile of Mith-A could provide a synergistic toxicity against the CRC.

Abstract
AIM In the current study, it was hypothesized that single nucleotide polymorphisms (SNPs) in the regulatory region of the IL-22 signaling pathway genes, including IL-22 and IL-22RA1 variants, may be associated with CRC susceptibility. BACKGROUND The important role of pro-inflammatory cytokines during tumorigenesis is well-established. In recent years, IL-22 has been linked with colorectal cancer (CRC) through a number of mechanistic and observational studies. METHODS The association of four polymorphisms in the IL-22 (rs1179251 and rs1179246) and IL-22RA1 (rs4648936 and rs10794665) genes with CRC risk were studied using a case-control design with 304 cases and 345 controls from the Iranian population. All 649 subjects were evaluated by PCR-RFLP method. RESULTS No significant difference was found in genotype and allele frequencies between the cases and controls for either IL-22 and IL-22RA1 gene variants or CRC risk before or after adjusting for confounders. CONCLUSION The current findings do not present any significant evidence for associations between variants in IL-22 signaling pathway genes and CRC. Complementary studies with greater sample sizes may be necessary to fully elucidate the nature of these associations.

Abstract
Recently, drug-eluting nanofibrous scaffolds have attracted a great attention to enhance the cell differentiation through biomimicking the extracellular matrix (ECM) in regenerative medicine. In this study, electrospun nanocomposite polycaprolactone (PCL)-based scaffolds containing synthesized graphene oxide (GO) nanosheets and osteogenic drugs, i.e. dexamethasone and simvastatin were fabricated. The physicochemical and surface properties of the scaffolds were investigated through FTIR, wettability, pH, and drug release studies. The cell viability, differentiation, and biomineralization were studied on mesenchymal stem cells (MSCs) by Alamar Blue, alkaline phosphatase (ALP) activity, and Alizarin Red-S staining, respectively. Uniformly distributed GO (thickness < 1 nm) in PCL nanofibers was observed by electron microscopy. It was revealed that the addition of GO and the drugs improved the hydrophilicity, cell viability, and osteogenic differentiation, in addition to pH changes, in comparison with PCL scaffolds. Despite the notable reduction in the cell viability, significant differentiation was revealed by ALP assay on PCL/GO-Dex scaffolds. Noteworthy, a twofold increase in the osteogenic differentiation was observed in comparison with the cells cultured in osteogenic differentiation medium, while a significant biomineralization was observed. The results of this study indicate the synergistic effect of GO and dexamethasone on improving osteogenic differentiation of drug-eluting nanocomposite scaffolds in bone tissue engineering applications.

Abstract
Municipal wastewater treatment facilities produce a lot of sludge which is concentrated with different pollutants. The sustainable design of the sludge disposal alternatives is of crucial importance for touristic cities like Mashhad in Iran. Increasing sludge generation and its accumulation in the city and more stringent legislations highlight the challenge of sludge disposal, recently. This study compares different alternatives to reach maximum possible environmental benefits as well as the most cost-effective technologies. In this study, life cycle analysis (LCA) assesses different scenarios for disposal of sewage sludge which is aerobically treated and dewatered for two real case studies. Alteymore and KhinArab are wastewater treatment units in the city. The scenarios include incineration, composting, and landfilling alternatives. The incineration and landfill scenarios are the least interesting solutions according to different life cycle impact categories. The heavy metals' emission to the soil worsens their impacts. Also, lifecycle cost analysis reveals that composting scenario is more cost-saving than others. However, main disadvantage of the composting scenario is its contribution in freshwater eutrophication. To move towards sustainability, the composting scenario is here determined as the best scenario for sludge disposal in Mashhad.

Abstract
Background: Pesticides have critical effects on human health. Because of the high amount of pesticides used, individual exposure is almost inevitable. According to the above-mentioned issues, few studies have been done in this area in Iran. Therefore, this study was conducted to evaluate the knowledge, attitude, and practice of pesticides use among farmers in Kabudrahang County, Hamadan Province, Iran. Materials and Methods: This cross-sectional study was conducted in Kabudrahang County. Data were collected from 262 farmer's sprayer, during April to July 2016. Data were collected, using convenience sampling through interviews with the farmers who had spryer during period spraying. Data collection instrument was a questionnaire that included three sections. Content validity ratio and content validity index indicators were used to measure the validity of questionnaire used from. Data were recorded in SPSS version 21.0 (SPSS Inc., Chicago, Illinois) and were analyzed using frequency analysis and Pearson correlation test. Results: Burning eyes and dizziness were the greater symptoms of poisoning with pesticides. Overall, most of them did not have proper knowledge. Many farmers had proper attitudes toward the use of personal protective equipment. However, 37.4% of them reported that the use of personal protective equipment is not easy. The farmers' practice toward the use of the personal protective equipment correlated with their knowledge and attitude (P < 0.001). Conclusion: It is proposed that educational sets consisted of acquaintance with poisons and their applications, storage, and carrying the pesticides, the methods for effective of different individual protection facilities, and utilizing the behavior to reduce the exposure to poisons should be developed and be available to farmers.

Abstract
Background: Despite the importance of emotional growth promotion among students, there is still a lack of standard emotional growth tools to evaluate the concept while developing interventional programs. The aim of present study was to devise and provide a valid and reliable instrument for measuring students' emotional growth. Methods: This study was conducted from 2016 to 2017 among university students. A questionnaire containing 79 items was made using focus group discussions with students and studying relevant texts. Exploratory factor analysis (EFA) (n = 188) was used to determine the construct validity of the questionnaire. Confirmatory factor analysis (CFA) (n = 38) was performed to assess the validity of the model. Reliability (n = 56) and repeatability (n = 31) of the questionnaire were assessed. Results: A 4-factor (positive identity, self-esteem, effective communication and motivation)and 21-item solution was found as the best solution, which explained 63.5% of total variancebetween the items. The results of CFA approved the validity of the model (CFI = 0.914, RMSEA= 0.070). Cronbach alpha (0.93) and Intra class correlation coefficient (0.91) approved the reliability and repeatability of questionnaire. Conclusion: The 21 items questionnaire seems to be a valid and reliable instrument to measure emotional growth among university students.

Abstract
Aims Iron deficiency (ID) is associated with adverse outcomes in heart failure (HF) but the underlying mechanisms are incompletely understood. Intracellular iron availability is secured by two mRNA-binding iron-regulatory proteins (IRPs), IRP1 and IRP2. We generated mice with a cardiomyocyte-targeted deletion of Irp1 and Irp2 to explore the functional implications of ID in the heart independent of systemic ID and anaemia. Methods and results Iron content in cardiomyocytes was reduced in Irp-targeted mice. The animals were not anaemic and did not show a phenotype under baseline conditions. Irp-targeted mice, however, were unable to increase left ventricular (LV) systolic function in response to an acute dobutamine challenge. After myocardial infarction, Irp-targeted mice developed more severe LV dysfunction with increased HF mortality. Mechanistically, the activity of the iron-sulphur cluster-containing complex I of the mitochondrial electron transport chain was reduced in left ventricles from Irp-targeted mice. As demonstrated by extracellular flux analysis in vitro, mitochondrial respiration was preserved at baseline but failed to increase in response to dobutamine in Irp-targeted cardiomyocytes. As shown by 31P-magnetic resonance spectroscopy in vivo, LV phosphocreatine/ATP ratio declined during dobutamine stress in Irp-targeted mice but remained stable in control mice. Intravenous injection of ferric carboxymaltose replenished cardiac iron stores, restored mitochondrial respiratory capacity and inotropic reserve, and attenuated adverse remodelling after myocardial infarction in Irp-targeted mice but not in control mice. As shown by electrophoretic mobility shift assays, IRP activity was significantly reduced in LV tissue samples from patients with advanced HF and reduced LV tissue iron content. Conclusions ID in cardiomyocytes impairs mitochondrial respiration and adaptation to acute and chronic increases in workload. Iron supplementation restores cardiac energy reserve and function in iron-deficient hearts.

Abstract
BACKGROUND It is clear that tobacco smoking and substance abuse have negative consequences on adolescent and youth's health. Tobacco smoking especially hookah smoking has increased worldwide especially among university students. This study aimed to determine the prevalence of risk-taking behaviors such as cigarette smoking, hookah smoking, alcohol use, and drug abuse and its predictors in students of Karaj universities. METHODS This cross-sectional study took place in Karaj in January and February 2014. The randomly selected sample consisted of 1959 college students. A self-administered questionnaire was used to measure risk-taking behaviors as well as demographic and related risk factors. Logistic regression model was performed in data analysis. RESULTS The prevalence of cigarette smoking was 9.3%. The prevalence of hookah smoking was 9.3%. 7% of students used illegal drugs and 9.5% of students used alcohol at least once in last 30 days. After adjustment for other factors, being male, living without parents, having smoker friends, and presence any smoker in the family were factors associated with students' risk-taking behaviors. The results showed the co-occurrence of risk-taking behaviors. CONCLUSIONS The prevalence of tobacco smoking and substance abuse, particular in males, are high. It seems that planning preventive interventions for this part of the population are necessary. This study emphasized the co-occurrence of risky behaviors, so, it is better high-risk behaviors simultaneously targeted at reducing or preventing interventions.

Abstract
Background: Current research findings demonstrate that acupuncture, a traditional Chinese medicine, has beneficial effects on several acute and chronic infectious and inflammatory diseases. Acupuncture promotes tissue healing and regulates immune response in various disease conditions. Cutaneous leishmaniasis (CL) is a parasitic disease caused by protozoan from genus Leishmania. Acupuncture is supposed to accelerate healing of CL because of common mechanisms involved in the cure of the CL lesions. Materials and Methods: 60 BALB/c mice were experimentally infected with L. major strain MRHO/IR/75/ER and divided into three groups: (1) Treatment group received acupuncture 2 times a week for 5 weeks (10 sessions) with intraperitoneal diazepam as a sedative agent. (2) Diazepam control group only received diazepam the same as the treatment group. (3) Control group did not receive any intervention. Size of the lesions was measured before the experiment, on session 5 and 10 and 4 weeks after the experiment. Parasite burden was evaluated by microscopic assay as well as quantitative real-time polymerase chain reaction technique. Results: Size of the lesions decreased significantly on session 5 in treated group in comparison with session 0 (P = 0.02) while the size of the lesions increased significantly in two control groups on session 5 and 4 weeks after treatment (P = 0.04 and P = 0.01 respectively). Mean parasite burden did not show a significant difference between or within groups on session 0 and 10 by any methods. Conclusions: This investigation showed that acupuncture decreased size of the CL lesions by session 5 in the BALB/c mice model, but did not cause a significant reduction in parasite burden.

Abstract
Background: The enterotoxigenic Staphylococcus aureus is considered as one of the most important cause of food poisoning that manifests with gastroenteritis, diarrhea, and vomiting. Its complications usually occur when bacterial virulence genes are produced. The most important virulence factors are cell-associated components, exoenzymes, exotoxins, enterotoxins, and enterotoxin-like toxins. Objectives: The present study aimed to study the presence of S. aureus and its virulence factors in chicken nuggets in Iran. Materials and Methods: Totally, 420 chicken nuggets from five brands were collected from Isfahan and Chaharmahal-va-Bakhtiari provinces, Iran. Samples were cultured and the positive results were studied using ELISA and PCR for detection of classical staphylococcal enterotoxins and sea-sej virulence genes, respectively. Results: Results showed that 27 (6.42%) of 420 samples were contaminated with S. aureus with bacteria concentration between 6.1 × 103 to 8.4 × 101/mL. Totally, 33.33% of isolates produced SEA, 4.16% SEB, 12.50% SEC, 8.33% SED, 12.50% SEA + SEC, and 12.50% SEA + SED. The most commonly detected genes were sea (25%), sea + seg (8.33%), sec (12.50%), sea + sed (12.50%), and sea + sec + sej (12.50%). Conclusions: S. aureus can easily contaminate the chicken nugget and this contamination is usually associated with significant presences of virulence genes. Consumption of these nuggets certainly is associated with gastrointestinal diseases. Therefore, some food safety and quality standards should be applied and performed in most of the Iranian food units to control growth of S. aureus and its virulence factors.

Abstract
BACKGROUND There is no information about the pattern of use of earphones and music players in Iranian adolescents. The aim of this study was to assess the prevalence and pattern of the use of earphone and music player devices as a main risk factor for hearing loss in adolescents of Tabriz city, northwest of Iran. METHODS In this cross-sectional study in November 2011, 2,359 high school students were randomly selected and were asked to complete a 20-item questionnaire about the pattern of using earphones and music players. RESULTS The results showed that 44.3% [confidence interval (CI) 95%: 38.3-50.3] of the respondents had a history of hearing problems that was significantly different between males and females (42.2% of males and 47% of females, p: 0.02). Notably, 36.8% of the participants stated that they listened to music without any rest or stop. Almost 49.6% (CI 95%: 44.4-54.4) of the students reported listening to 'somewhat loud' (gain setting at 50%) or 'very loud' (gain setting more than 50%) volume level of music. In terms of the kind of earphones, 17.1% of the participants used headphones, 34.8% used earbud-style headphones, 32.3% used supra-aural headphones, and 15.8% of them did not use any type of earphones. CONCLUSIONS Students have risky patterns of using earphones and music-listening devices. Planning educational programs in this domain for adolescents especially in high schools is necessary.

Abstract
UNLABELLED Objective(s ): Targeting the neuropeptide systems has been shown to be useful for the development of more effective antipsychotic drugs. Neurotensin, an endogenous neuropeptide, appears to be involved in the mechanism of action of antipsychotics. However, the available data provide conflicting results and the mechanism(s) by which antipsychotics affect brain neurotensin neurotransmission have not been identified. Therefore, we aimed to investigate the effects of fluphenazine and amisulpride on brain regional contents of neurotensin considering the role of cannabinoid CB1 receptors which interact with neurotensin neurotransmission. MATERIALS AND METHODS Fluphenazine (0.5, 1, and 3 mg/kg) or amisulpride (3, 5, and 10 mg/kg) were administered intraperitoneally to male Wistar rats either for one day or 28 consecutive days. Twenty four hours after the last injection of drug or vehicle, neurotensin contents were determined in the mesocorticolimbic and nigrostriatal dopamine regions by radioimmunoassay. In the case of any significant change, the effect of pre-treatment with CB1 receptor antagonist, AM251 was investigated. RESULTS Chronic, but not acute, treatment with the highest dose of fluphenazine or amisulpride resulted in significant enhancement of neurotensin contents in the prefronatal cortex and nucleus accumbens. Fluphenazine also elevated neurotensin levels in the anterior and posterior caudate nuclei and substantia nigra. Neither amisulpride nor fluphenazine affected neurotensin contents in the amygdala or hippocampus. Pre-treatment with AM251 (3 mg/kg) prevented the neuroleptic-induced elevation of neurotensin. AM251 showed no effect by itself. CONCLUSION The brain neurotensin under the regulatory action of CB1 receptors is involved in the effects of amisulpride and fluphenazine.

Abstract
OBJECTIVE(S) A growing interest has recently been attracted towards the identification of plant-based medications including those with protective effects against cognitive impairment. Sesamol has shown promising antioxidant and neuroprotective effects, therefore, we aimed to evaluate its therapeutic potential in epilepsy which is commonly associated with oxidative stress and cognitive impairment. MATERIALS AND METHODS Male Wistar rats received pentylenetetrazole (PTZ) (30 mg/kg, IP) once every other day until the development of kindling, i.e., the occurrence of stage 5 of seizures for three consecutive trials. After the completion of kindling procedure, behavioural tests including elevated plus maze and passive avoidance were performed in order to assess learning and memory. Oxidative stress was assessed by estimation of lipid peroxidation and reduced glutathione. The effects of pretreatment with sesamol (10, 20, and 30 mg/kg, IP) against PTZ-induced seizures, cognitive impairment and oxidative stress were investigated. RESULTS 32.45 ± 1.86 days after treatment with PTZ, kindling was developed that was associated with myoclonic jerks and generalized tonic-clonic seizures. Moreover, PTZ kindling induced a remarkable cognitive impairment and oxidative stress. Sesamol (30 mg/kg) significantly delayed the development of kindling and prevented seizure-induced cognitive impairment and oxidative stress. CONCLUSION Sesamol exerts ameliorative effects in the experimental model of epilepsy. This phytochemical may be considered as a beneficial adjuvant for antiepileptic drugs.

Abstract
Undular hydraulic jumps are characterized by a smooth rise of the free surface, followed by a train of stationary waves. These jumps sometimes occur in natural waterways and rivers. Numerical difficulties are especially distinct when the flow condition is close to the critical value because of the high sensitivity of the near-critical flow field to flow and channel conditions. Furthermore, the free surface has a wavy shape, which may indicate the occurrence of several transitions from supercritical to subcritical states and vice versa (i.e., undular hydraulic jumps). In this study, a flow model is used to predict an undular hydraulic jump in a rectangular open channel. The model is based on the general two-dimensional, Reynolds-averaged, Navier-Stokes flow equations. The resulting set of partial differential equations is solved using the FLOW-3D solver. The results are compared with the experimental data to validate the model. The comparative analysis shows that the proposed model yields good results. Several types of undular hydraulic jumps occurring in different situations are then simulated to prove the potential application of the model.

Abstract
OBJECTIVE This study examined the prevalence of smoking, the rates of transitions, and predictors of transition through the three stages of smoking. METHODS A total of 1785 high school students in Tabriz (northwest of Iran) were assessed at 2 time points with a 12-month interval in 2005 and 2006, regarding changes in smoking stages. The predictor variables were measured when the students were in the 10th grade. Logistic regression was employed to predict the different smoking stages at grade 11. RESULTS The results showed that 14.3% (95% confidence interval, 12.3%-16.4%) and 2.8% (2.0%-4.0%) of the never smokers became experimenters and regular smokers, respectively, whereas 16.5% (12.4%-21.7%) of the experimenters became regular smokers. Among never smokers, participation in groups with at least one smoker (odds ratio, 1.24 (95% confidence interval, 1.05-1.47)), having smoker friends (1.85 (1.21-2.83)), and a positive attitude toward smoking (1.22 (1.02-1.46)) predicted smoking experience. Among the experimenters, those who had general risk behaviors (2.56 (1.12-5.87)) and participated in groups with at least one smoker (2.58 (1.26-5.31)) significantly progressed to becoming a regular smoker at the follow-up. CONCLUSION Prevention of smoking in adolescence should begin by focusing on the predictors of transition through smoking stages, especially participating in smoker groups.

Abstract
BACKGROUND We investigated longitudinally the prevalence of smoking according to three stages of smoking (never smoking, experimenting the smoking, and regular smoking), the rates of transition from one stage to another one, and determinant predictors of transition through these stages of smoking. METHODS Of all 10(th) grade students in Tabriz, 1785 students were randomly selected and assessed twice, with a 12-month interval, with respect to the changes of stage. The predictor variables were measured when the students were in the 10(th) grade. Logistic regression and principal component analysis were used to analysis data at grade 11. FINDINGS Of 1785 students, 14.3% (CI 95%: 12.3-16.4) and 2.8% (CI 95%: 2.0-4.0) of the never smokers became experimenters and regular smokers, respectively and 16.5% (CI 95%: 12.4-21.7) of the experimenters became regular smokers. Among never smokers, participating in smoker groups (OR=1.24), having smoker friends (OR=1.85) and a positive attitude towards smoking (OR=1.22) predicted experimentation; and participating in smokers groups (OR=1.35) and a lower socioeconomic class (OR=0.36) predicted regular smoking. Among experimenters, students having general high risk behaviors (OR=2.56) and participating in smoker groups (OR=2.58) were distinguished as those who progressed to regular smoking in follow-up. CONCLUSION Programs aimed at smoking prevention and intervention should incorporate plans which focus on predictors of transition through smoking stages, and targeting participation in smoker groups.

Abstract
Limited information is available on adolescent's substance abuse in Iran. The aims of this study are to estimate incidence rate of substance abuse among the sample of 10-grade male students in Tabriz City (northwestern region of Iran), and to evaluate the associated factors. Of all grade-10 male students in Tabriz, 1785 (13.7%) were randomly sampled, and were assessed twice. A self-administered questionnaire with 48 questions was distributed to students in February and March 2005. After one year (February and March 2006), another questionnaire with 10 items was distributed to those students to determine the incidence rate of substance abuse. The influence of different factors on substance abuse was evaluated with a logistic regression model. The mean age of the subjects was 16.3+/-0.87 (min. 15, max. 19) years. At the end of follow-up, 10.1% and 2.2% of students reported incidence of alcohol use and drug abuse respectively. This study has shown low prevalence of substance abuse, but higher incidence rate of substance abuse.

Abstract
Adolescent substance abuse potentially holds a number of negative implications for the health and well-being of the individual, including increased risk for injury and death from interpersonal violence, motor vehicle accidents, and drowning, increased probability of engaging in high risk sexual behaviors; and increased risk for suicidal ideation and behaviors. The aim of this paper is to estimate prevalence of substance abuse among the sample of 10th grade male students in Tabriz City, and to evaluate the associated factors. Of all 10th grade male students in Tabriz, Iran, 1785(13.7%) were randomly sampled. Mean age of the subjects was 16.3+/-0.87 years. A self-administered questionnaire was used to collect demographic data, substance abuse, smoking status and friends smoking. The influence of different factors on substance abuse was evaluated with a logistic regression model. Among 1785 students 226 (12.7%, 95% CI: 11.2-14.3) had ever used alcohol and 36 (2.0%, 95% CI: 1.5-2.8) had used drugs. The results indicate that older age (OR=1.55), having general risk taking behavior (OR=1.70), higher smoking stage (OR=3.70), having self-injury (OR=1.22), higher socioeconomic class (OR=1.62), and ever use of illicit drugs (OR=5.72) were factors associated with student's ever use of alcohol. This study has shown low prevalence of substance abuse and determined some of its risk factors among students. More studies about adolescent population are necessary to approve the observed results of this study and thus allow for a certain generalization of the observations.
