Abstract The present study aims to examine the anti-diabetic effects of fullerene C60 nanoparticle, as an anti-oxidant compound, on serum glucose level, body weight, food and water intake, and pancreatic oxidative stress in the rats with type 1 diabetes. Diabetes mellitus was induced by single intravenous injection of streptozotocine (45 mg/kg) into the tail vein of the rats. Four groups of rats were divided as follow: normal, normal treatment, diabetic, and diabetic treatment groups. Normal treatment and diabetic treatment groups received intra-orally fullerene (1 mg/ kg/daily) up to day 60 following streptozotocine injection. Oxidative stress markers in the pancreas were evaluated on day 60 after inducing diabetes mellitus. Injection of streptozotocine significantly increased serum glucose level as well as food and water intake on all experimental days; it decreased body weight on day 60. Streptozotocine increased MDA level and decreased GSH level and SOD activity in the pancreas. Fullerene significantly decreased food and water intake and increased body weight as compared with the diabetic group. Fullerene also could normalize the pancreatic MDA and GSH markers. The present study suggested that fullerene can decrease diabetic symptoms via its anti-oxidant activity in the pancreas in the rats with type 1 diabetes mellitus.

Abstract Introduction Internet addiction disorder has reportedly become an important cause of health and social problems. The aim of this study was to investigate the effectiveness of cognitive-behavioral group therapy for internet addiction symptoms, quality of life, and mental health of students with internet addiction. Methods This was a quasi-experimental study with pretest-posttest measures and a control group. The statistical population of the study consisted of all students at Tehran universities in the academic year of 2018-19. The target group was selected through an internet addiction test and a clinical interview using a targeted sampling method and was divided into experimental and control groups by randomization. The experimental group participated in fifteen 90-minute cognitive-behavioral group therapy sessions. Before, immediately after, and 3 months after the treatment, the internet addiction symptoms of both groups were evaluated to assess mental health with the IAT, quality of life (QOL), and SCL-90-R questionnaires. Data were analyzed with ANCOVA analysis using SPSS Statistics 20 software. Results After treatment, cognitive-behavioral therapy groups showed reductions in internet addiction scores (p < 0.05). Results showed that the cognitive-behavioral group therapy was effective for improving quality of life (p < 0.05) and mental illnesses (p < 0.05) in students with internet addiction. Conclusions Cognitive-behavioral group therapy can enhance awareness and mental health of students with internet addiction. Therefore, this intervention can be used as a beneficial treatment to reduce internet addiction symptoms and improve the condition of people with behavioral addictions such as internet dependency.

The facile chemical synthesis method was used for preparing Trimetallic Fe-Co-V/Zeolite and Fe-Co-Mo/Zeolite composite nanostructures. The structural functionalities and morphological observations were obtained using characterization techniques of field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Fourier transfer infrared (FT-IR) spectroscopy, and energy dispersive spectroscopy (EDS). The results indicated the formation of irregular and no-shaped nanostructures for both Fe-Co-V/Zeolite and Fe-Co-Mo/Zeolite composite nanostructures. The optical characterization was conducted by UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS). The optical studies were revealed band-gap energies equivalent to 3.0 and 3.5 eV for Fe-Co-V/Zeolite and Fe-Co-Mo/Zeolite samples. The morphological features of sample were investigated with a Zeiss (EM10C -Germany) transmission electron microscope (TEM) operating at 100 kV respectively.

Objective: This was the first national epidemiological study on oppositional defiant disorder (ODD) in Iran, which provided new information about the prevalence, comorbidities, and sociodemographic predictors of ODD. Methods: Data from a face-to-face household survey of 30,532 children and adolescents aged 6-18 years were collected from across all 31 provinces of Iran using a multistage cluster sampling design. The Persian version of the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children – Present and Lifetime Version (K-SADS-PL) was used in this study. Results: The lifetime prevalence of ODD was found to be 3.9%. ODD was significantly more common in boys than girls and appeared in late adolescence more frequently than in childhood. A lower prevalence of ODD was found among participants who lived in rural areas. ODD is highly likely to co-occur with attention deficit hyperactivity disorder, separation anxiety disorder, generalized anxiety disorder, and depressive disorders. Conclusions: The findings of this national population-based study confirm and extend previous findings on the prevalence, comorbidities, and sociodemographic predictors of ODD.

Abstract Methotrexate (MTX) was shown to cause oxidative stress and liver damage. The objective was to investigate the possible protective effects of Matricaria Chamomilla L. (chamomile) extract with anti-oxidant and anti-inflammatory properties on the methotrexate-induced liver toxicity. Twenty four Wistar rats were divided into four groups. MTX group was injected intraperitoneally on days 7 and 14 with 20 mg/kg methotrexate. Groups CE200 (chamomile extract 200 mg/kg/day) and CE300 (chamomile extract 300 mg/kg/day) received the same dose of methotrexate added with chamomile extract orally for 15 days at 200 mg/kg and 300 mg/kg respectively and the last group was healthy control group. Results of biochemical analyses indicated serum liver biomarkers (aminotransferases), alkaline phosphatase (ALP), albumin, and liver content of anti-oxidant enzymes (catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px)), reduced glutathione (GSH) and total anti-oxidant capacity (TAC) significantly increased (P <0.05-0.001) to normal in the CE treated groups compared to those of the MTX group. Serum bilirubin and hepatic malondialdehyde (MDA) levels significantly increased (P ˂0.001) in MTX group compared to those of the control group and decreased in CE200 and CE300 groups compared to those of the MTX group. Histopathological study showed inflammatory damage, necrotic cells and lipid infiltration in MTX group. In the groups treated with the chamomile extract, a significant improvement was observed in liver tissue in response to increased dose of the extract. In conclusion, chamomile extract administration could have a protective role in methotrexate-induced liver toxicity in rats through improving anti-oxidant defense system.

RESUMEN Se realizó un experimento de campo en un diseño de bloques completos al azar con cuatro niveles de azufre, S0, S1, S2 y S3, incluyendo 0, 12, 24 y 36 kg ha-1 (respectivamente) junto con 115 kg N ha-1, para evaluar el rendimiento económico de una variedad de canola (Hyola401) en Abandankash en el Distrito Central del condado de Sari en el norte de Irán. Se registraron parámetros tales como actividad de la nitrato-reductasa de la hoja, contenido de nitrato en raíz, contenido de azúcares en hojas y en raíz, actividades de peroxidasa en raíz y de catalasa en hojas y rendimiento de semilla. Los resultados del análisis de varianza revelaron diferencias altamente significativas entre los caracteres para la mayoría de los rasgos como contenido de nitrato y de azúcares en hojas y raíz, actividades de peroxidasa en raíz y de catalasa en hojas y rendimiento de semillas. Debido a una correlación positiva significativa entre la nitrato- reduc-tasa de la raíz y el rendimiento de la semilla, el aumento de esta enzima en la raíz mediante la aplicación de azufre tiene un efecto acelerador en el rendimiento de la semilla de colza. Una correlación positiva altamente significativa determinada entre el contenido de azúcar en la hoja y el rendimiento de la semilla (0.75**) indica que los niveles crecientes de azufre tuvieron un efecto directo sobre el contenido de azúcar en la hoja, lo que tuvo un efecto acelerador sobre el peso del rendimiento del grano. La aplicación de azufre aumentó significativamente el rendimiento de la semilla sobre el control (nivel de S0) y varió de 2744 a 3215 kg ha-1 en S0 y S3, respectivamente.

ABSTRACT A field experiment was conducted in a randomized complete block design with four sulfur levels, S0, S1, S2 and S3, including 0, 12, 24 and 36 kg ha-1 (respectively) along with 115 kg N ha-1, to evaluate the economic yield of the rapeseed variety (Hyola401) in Abandankash in the Central District of Sari County in Northern Iran. Parameters such as activity of leaf nitrate reductase, root nitrate content, contents of sugars in leaves and root, root peroxidase activity, and leaf catalase activity as well as seed yield were recorded. The results of the analysis of variance revealed that there were highly significant differences between characters for the majority of the traits such as contents of sugars and nitrate in leaves and root, root peroxidase activity, leaf catalase activity, and seed yield. Due to significant positive correlation between activity of root nitrate reductase and seed yield, increasing this enzyme in roots by sulfur application would have an accelerating effect on rapeseed seed yield. A highly significant positive correlation determined between leaf sugar content and seed yield (0.75**) indicated that increasing levels of sulfur had a direct effect on leaf sugar content, which had an accelerating effect on the weight of seed yield. Sulfur application significantly increased seed yield compared to the control (S0 level), and it ranged from 2744 to 3215 kg ha-1 in S0 and S3.

Objective: In Western countries, the prevalence of childhood trauma (CT) ranges from 15 to 25%. CT might be indirectly associated with lower parental socioeconomic status and educational attainments. The aims of this cross-sectional study were fourfold: to assess prevalence of CT in a large sample of Iranian children; to compare the Iranian prevalence rates with those of Western countries; to explore gender-specific patterns; and to explore possible socioeconomic predictors. Method: The sample comprised 608 children (mean age 11.49 years, 51.5% females). All completed the Farsi version of the Trauma Symptoms Checklist for Children. Additionally, parents reported on their current employment status and highest educational level. Results: Trauma symptoms were reported by 20 of 295 boys and 23 of 313 girls. The overall prevalence was 7.1%. Child-reported trauma symptoms were not associated with parents’ socioeconomic status or highest educational level. Compared to prevalence findings from U.S. national surveys (ranging from 15-25% of children and adolescents), the prevalence among 11- and 12-year-olds in the present study was considerably lower. Conclusions: The overall prevalence of reported trauma symptoms among a large sample of Iranian children was unrelated to parents’ socioeconomic status, and was lower than that reported in U.S. surveys.

Detailed information derived from a soil moisture characteristics curve (SMC) helps in water flow and solute transport management. Hence, prediction of the SMC from soil particle size distribution (PSD), which is easy to measure, would be convenient. In this study, we combine an integrated robust PSD-based model and a Van Genuchten SMC model to predict a continuous form of SMC using sand, silt and clay percentages for 50 soils selected from the UNSODA database. We compare the performance of the proposed approach with some previous prediction models. The results indicated that the SMC can be predicted and modelled properly by using sand, silt, clay and bulk density data. The model's bias was attributed to the high fine particle and organic carbon (OC) content. We concluded that independence of the proposed method from the database and any empirical coefficients make predictions more reliable and applicable for large-scale water and solute transport management.

ABSTRACT Canine taeniids are among the major tapeworms with remarkable medical and economic significance. Reliable diagnosis and differentiation of dog taeniids using simple and sensitive tools are of paramount importance for establishing an efficient surveillance system. Microsatellites as abundant unique tandem repeats of short DNA motifs are useful genetic markers for molecular epidemiological studies. The purpose of the present study was to find a primer pair for rapid differentiation of major tapeworms of dogs, Taenia hydatigena, T. multiceps, T. ovis and Echinococcus granulosus, by screening existing nucleotide data. All the mitochondrial genome records as well as non-coding ITS1 sequences of Taeniidae species were downloaded from Nucleotide database from NCBI. For prediction and analysis of potential loci of STR/SSR in ITS1 as well as mitochondrial regions, we used ChloroMitoSSRDB 2.0 and GMATo v1.2. software. Different tapeworm species were categorized according to different motif sequences and type and size of each microsatellite locus. Three primer sets were designed and tested for differentiating taeniid species and evaluated in a conventional PCR system. Four taeniid species were successfully differentiated using a primer pair in a simple conventional PCR system. We predicted 2-19 and 1-4 microsatellite loci in ITS1 and mitochondrial genome, respectively. In ITS1, 41 Di and 21 Tri motifs were found in the taeniids while the majority of the motifs in the mitochondrial genome were Tetra (89) and Tri (70). It is documented that the number and diversity of microsatellite loci is higher in nuclear ITS1 region than mostly coding mitochondrial genome.
