- چکیده انگلیسی: Background and Objective: Adolescence is a complex, sensitive and multidimensional period in the human development process. Nutrition quality is the main factors that have an essential role in the growth and maturity of adolescents. Adolescent’s health literacy is an importance because individuals with high levels of health literacy have better health outcomes than individuals with limited health literacy.
Materials and Methods: The present study is an experimental intervention that was conducted on 15-18 years old female adolescents studying in high schools of Zahedan, Iran. The data collection tools in this study consisted of three questionnaires. Health literacy data were collected by HELMA questionnaire and its validity has been proven by Cronbach's alpha coefficient of 0. 95. Educational posters, booklets (designed by the researcher) and PowerPoint were used to conduct training programs during 3 sessions of 45 to 60 minutes. A post-test was carried out in the control and intervention groups One month after the last session. The SPSS software version 26 was used to analyze the data.
Results: The results showed a significant difference between health literacy and nutritional performance of students in the intervention and control groups after the intervention (P-value <0.001), therefore; that educational intervention increased the health literacy and nutritional performance in students. A significant and positive relationship was found between students' health literacy and nutritional performance (P-value <0.05).
Conclusion: According to the results of the present study, it is necessary for policymakers and planners to improve the health literacy of adolescents and students through intervention programs to promote health literacy, awareness, attitude, and nutritional behaviors in adolescent’s population.

- چکیده: ریزنمونههای برگ کالادیوم در شرایط درون شیشهای روی محیطهای MS همراه با 25 غلظت مختلف از BAP و NAA بهمنظور تعیین غلظتهای مناسب برای ریزازدیادی کشت شدند. تمام ترکیبات تشکیل کالوس را روی ریز نمونهها القا کردند. تولید کالوس روی ریزنمونههای برگی رشد یافته روی محیط شاهد بسیار کم بود. محیط غنی شده با 4 میلیگرم بر لیتر BAP + 5/0 میلیگرم بر لیتر NAA برای تشکیل کالوس موثرترین بودند. بیشترین تعداد نوشاخهها (43/6 در ریزنمونه) و بیشترین تعداد ریشهها (56/5 در ریز نمونه) بهترتیب روی محیطهای حاوی یک میلیگرم بر لیتر BAP + 5/0 میلیگرم بر لیتر NAA و 3 میلیگرم بر لیتر BAP + 5/0 میلیگرم بر لیتر NAA تولید شدند. گیاهچههای باززایی شده در شرایط گلخانهای رشد داده شدند و بطور موفقیتآمیزی سازگار گردیدند.
- چکیده انگلیسی: Leaf explants of kaladium dwubarwne Caladium bicolor (Aiton) Vent., were cultured in vitro on MS media supplemented with 25 different concentrations of BAP and NAA in order to determine the appropriate concentrations for micropropagation. All combinations induced callus formation on explants. Callus production on leaves explants grown on control medium was very low. The medium enriched with 4 mg l-1 BAP + 0.5 mg l-1 NAA was the most effective for callus formation. The highest number of shoots (6.43 per explant) and roots (5.56 per explant) were regenerated on media containing 1 mg l-1 BAP + 0.5 mg l-1 NAA and 3 mg l-1 BAP + 0.5 mg l-1 NAA, respectively. The regenerated plantlets were grown in a greenhouse and acclimatized successfully.

- چکیده: Stress management is considered as an important factor in nowadays landscape. Therefore this research was conducted using a factorial experiment based on a randomized completely design with regulated deficit irrigation at four levels (100, 75, 50, and 25% of lawn irrigation requirement) and three replicates to evaluate some biochemical and physiological traits on four groundcover plants (Lolium perenne, Potentilla spp., Trifolium repens and Frankinia spp.) with the potential use in landscape. Results showed that Frankinia spp. and 75% lawn irrigation requirement bears the highest proline content with same amount (0.84 mg/g fresh weight) and on the other hand highest (32.61 mg/g fresh weight) and lowest (15.95 mg/g fresh weight) chlorophyll content was shown in control (irrigation treatments) and Frankinia spp., respectively. For total soluble carbohydrates content, highest amount (1.54 mg/g fresh weight) belongs to Lolium perenne whereas the lowest (0.79 mg/g fresh weight) belongs to Trifolium repens. Trifolium repens also had the most DPPH free radical-scavenging assay (75.05%) among species. In general, regulated deficit irrigation affects different biochemical characteristics of examined groundcover plants significantly, but as a managing method applying it to below the damaging point for landscape plants can be a good method for water consumption management in this manner.

- چکیده:
- چکیده انگلیسی: Background: To date, with rapid increase of bilingual children, more attention about different patterns of the bilingual children narratives is needed. The aim of this study was to compare microstructure level of narratives generated by typical developing kindergarten children who were bilingual in Persian and Balochi with monolingual Persian speakers.Method: Thirty Persian-speaking monolingual and thirteen available bilingual children (aged 48 months old) participated in this study. Children’s story telling was audio-recorded and analyzed using the Persian-NAP (Narrative Assessment Protocol) guidelines. Results: All of the NAP indicators include of group structure, phrase structure, modifiers, noun and verbs didn’t show significant difference between monolingual and bilingual children (0.06≤p≤0.5).Conclusion: We didn’t find different performance in the five NAP indicators between bilingual and monolingual children. It may be suggested that the different patterns of creating phrases and sentences in two languages don’t affect the grammatical use of them in second language.

- چکیده: رشد و نمو دانهالهای گوجهفرنگی (Solanum lycopersicum L.) بطور قابل مالاحظهای توسط تنش آبی مهار می-شود. پوترسین در تحمل به تنش آبی نقش دارد. با این حال، اطلاعات بسیار محدودی در مورد اثرات کاربرد بیرونی پوترسین بر گیاهان از جمله گوجهفرنگی وجود دارد. این آزمایش به منظور بررسی کاربرد پوترسین بر برخی صفات فیزیولوژیکی و بیوشیمیایی گوجهفرنگی در شرایط تنش آبی انجام شد. گیاهان در معرض سه شرایط آبی قرار گرفتند: 100 درصد ET0 به عنوان تیمار خوب آبیاری شده (یا شاهد)، 75 و 50 درصد ET0 به عنوان تیمارهای تنش آبی. کاربردهای برگی پوترسین در غلظتهای 5/0 و 1 میلیگرم در لیتر بود در حالی که گیاهان شاهد با آب مقطر اسپری شدند. تنش خشکی باعث کاهش معنیداری در رشد و بهرهوری گیاه و کاهش سطح برگ، ارتفاع بوته و عملکرد میوه در 50 درصد ET0 نسبت به تیمار شاهد شد. همچنین آنزیمهای آنتیاکسیدانی مانند SOD ، PPO و CAT با افزایش شرایط تنش آبی افزایش یافت. کاربرد پوترسین باعث بهبود صفات رشدی، ارتفاع بوته، عملکرد میوه و سطح برگ در شرایط تنش آبی شد. علاوه بر این، محتوای PPO و فعالیتهای آنزیم CAT و SOD با استفاده از پوترسین نیز بهبود یافت. نتایج این تحقیق نشان داد که کاربرد برگی پوترسین در سطح مناسب ممکن است به عنوان ماده مؤثر در تحریک فرآیندهای فیزیولوژیکی و القای بیوسنتز متابولیتهای با ارزش عمل کند که این امر میتواند تأثیر منفی تنش خشکی بر زیست توده، کیفیت و کمیت گیاه را جبران کند.
- چکیده انگلیسی: The growth and development of tomato seedlings (Solanum lycopersicum L.) are drastically inhibited under water stress. Putrescine (PUT) is involved in water stress tolerance. However, very limited information is known concerning the effects of exogenous application of PUT on plants including tomato. This experiment was carried out to study the application of putrescine on some physiological and biochemical factors of tomato under the water stress. Plants were exposed to three water conditions: 100 % (ET0) as well- watered treatment (or control), 75 and 50% of ET0 as a water stress treatments. Foliar applications of PUT were applied at 0.5 and 1 mgL-1 while control plants were sprayed with distilled water. Drought stress significantly impaired the plant growth and productivity, and reduced leaf area, plant height, fruit yield at 50% ET0 compared to control treatment. Also antioxidant enzymes such as SOD, PPO, and CAT were increased by increasing the water stress conditions. The application of PUT improved the growth characters, plant height, fruit yield, and leaf area under water stress. Furthermore, PPO content and CAT and SOD enzyme activities were also improved by applying PUT. The results of this study indicated that foliar application of putrescine in proper level may act as elicitor to trigger physiological processes and induce valuable metabolites biosynthesis, which may compensate the negative impacts of drought stress on plant biomass, quality and quantity.

- چکیده:
- چکیده انگلیسی: Background & aim: Inability in childbearing is considered a deviation from the norms; therefore, the stigmatized women need to develop some effective strategies to meet this tough challenge. The present study was conducted to determine the effect of infertility counseling programs on perceived stigma among infertile women who were candidates for intrauterine insemination.
Methods: This quasi-experimental study was carried out on 135 women referring to the infertility center, Zahedan, Iran, during July 7th to December 12th, 2018. The subjects in the intervention group were invited to take part in a three-session counseling program, whereas the control group received the routine care. The perceived stigma was evaluated using the Infertility Stigma Scale. The data analysis was performed in SPSS software (version 21) using Fisher’s exact test, Chi-square test, Mann-Whitney U test, and independent t-test.
Results: Theresults indicated that women in the intervention group expressed less infertility stigma, as compared to the control group (P <0.001). Additionally, these women manifested less infertility stigma in subscales including public stigma (23.42±2.84 vs. 12.52±2.14; p <0.001), self-devaluation (19.58±2.04 vs.9.65±1.50; p <0.001), social withdrawal (14.04±1.65 vs.7.25±1.54; p <0.001), and family stigma (12.70±1.94 vs. 9.23±1.72; p <0.001) after the intervention.
Conclusion: Infertility counseling can help women to remedy their sense of self-devaluation. Additionally, establishment of close relationship with others and appropriate release of innermost feelings and thoughts can decrease the perceived public and social stigma.- انتشار مقاله: 29-02-1398

- چکیده:
- چکیده انگلیسی: Objective(s): Acinetobacter baumannii is one the most dangerous opportunistic pathogens in hospitalized infections. This bacterium is resistant to 90% of commercial antibiotics. Therefore, developing new strategies to cure A. baumannii-infections is urgent. The DNA vaccines new approach in which the immunogen can be directly expressed inside the target cells through cloning of immunogen into an expression vector. The outer membrane protein A(OmpA) is one the critical factors in pathogenicity of A. baumannii which has been repeatedly described as a powerful immunogen to trigger the immune responses. As the pure form of the OmpA is insoluble, vaccine delivery is very hard.
Materials and Methods: We previously cloned the ompA gene from A. baumannii into the eukaryotic expression vector pBudCE4.1 and observed that the OmpA protein has been considerably expressed in eukaryotic cell model. In current study, the immunogenic potential of pBudCE4.1-ompA has been evaluated in mice model of experimental. The serum levels of IgM, IgG, IL-2, IL-4, IL-12 and INF-γ were measured by enzyme-linked immunosorbent assay (ELISA) after immunization with ompA-vaccine. The protective efficiency of the designed-DNA vaccine was evaluated following intranasal administration of mice with toxic dose of A. baumannii.
Results: Obtained data showed the elevated levels of IgM, IgG, IL-2, IL-4, IL-12 and INF-γ in serum following the vaccine administration and mice who immunized with recombinant vector were survived more than control group.
Conclusion: These findings indicate ompA-DNA vaccine is potent to trigger humoral and cellular immunity responses although further experiments are needed.- انتشار مقاله: 08-01-1397

- چکیده انگلیسی: Background: Preterm birth is one of the most remarkable reasons for neonatal and infant mortality and morbidity across the world. This study aimed to determine risk factors of premature infants in the rural area of Azadshahr city, Iran. Materials and Methods: Acase-control study was conducted on all premature and low birth neonates (less than 37 weeks and weight less than 2500 grams). Data were collected by records in 30 health houses located in the rural areas of Azadshahr city durring 2013 to 2016. Two groups (case and control) were matched by gender and health houses. A trained midwife was collected data by using of a researcher-made checklist. To describe mean and standard deviation of the demographic characteristics, descriptive methods were used.To analyze, inferential statistic tests such as Chi- square, and independent t-test were implemented through SPSS (version,16). Significant level was also taken <0.05. Results: In total, 112 girl infant and 101 boy infant were explored. The mean age of mother in the case and control groups was 26.14+ 8.4 and 25.67+ 9.1 years old respectively.There was a significant difference between the two groups in terms of prenatal care and pregnancy complications. In addition, a remarkable relations was found between polytocous and delivery time (P<0.05). Conclusion: Providing mothers with necessary information in terms of interval between births, and the importance of prenatal cares in the pregnancy period to prevent complication seems to be likely useful.

- چکیده:
- چکیده انگلیسی: Objectives: This study aims to assess the relationship between the frequency of aggressive behaviors, life satisfaction (LS) and self- rated health (SRH) and counseling with family members in a representative sample of Iranian children and adolescents.
Methods: In this nationwide study, 14880 school students, aged 6-18 years, wereselected by cluster and stratified multi-stage sampling method from 30 provinces inIran. The World Health Organization Global School-based Health Survey questionnaire(WHO-GSHS) was used.Mental disorders were assessed through the WHO-GSHSquestionnaire that consisted of worthless, angriness, anxiety, insomnia, confusion, depression, and worried.
Results:.The results showed that 45.7% of boys and 44.8% of girls share their problem with their brother or sister. The prevalence of physical fight, victim, and bully was not different in children and adolescents who consulted with their brother or sister compared with those who did not consult (p> 0.05). In addition, 60.4% of boys and 66.0% of girls share their problems with friends. Physical fight and bully were less prevalent in children and adolescents who consulted with their friends compared with those who did not consult (p< 0.001). According to this study, the prevalence of LS and SRH “good” was also lower in children and adolescents who share their problem with their father or mother compared with those who did not consult (p< 0.001).
Conclusion:Children and adolescents should be encouraged to consult with their parents about their problems. Parents should offer their children an opportunity to express their views and wishes about their problems.- انتشار مقاله: 04-05-1395
