Background: Stress is one of the perceived feelings in university students that plays an important role in students' academic performance and achievement which is often overlooked. Therefore, the present study was conducted to identify and compare stressors in medical and non-medical students. Materials and methods: In this comparative descriptive study, a sample of 380 medical and non-medical students of Islamic Azad University in Tehran, who were at the first semester of the 2019-2020 academic year were selected. The study tools included a demographic information and stressors questionnaire. Data were analyzed by SPSS-16 software using descriptive statistics and independent t-test at the significant level of 0.05. Results: There was a statistically significant difference between the medical and non-medical students of Tehran Islamic Azad University, in terms of problems related to "academic affairs", "emotions", "job, welfare and finance", "marital issues, marriage and choice of spouse", "social issues " and " family issue” (p<0.05). However, no statistically significant difference was observed between the medical and non-medical students in terms of problems related to "burnout", "unexpected events such as natural disasters”, "different accidents" and "behavioral characteristics and habits, and health issues" (p>0.05). Conclusion: The results of present study can help managers in developing educational frameworks to improve and create a suitable educational environment, recognize and improve coping strategies among students and to provide effective education for parents in order to reduce the stressors of students.

Background: Exercise training and the use of medicinal plants are helpful in the prevention and treatment of diabetes. The purpose of this study was to evaluate effect of eight-week high-intensity interval training and Aloe vera consumption on serum adiponectin and beta cells function in diabetic male rats. Materials and methods: In this experimental study, 32 diabetic Wistar rats with STZ (weight of 240-260 grams and an average age of 12 weeks) were randomly divided into four groups, including the “control group”, the “training group”, the “supplement group” and the “training + supplement group”. Training group was exposed to high-intensity interval training with %90 VO2max intensity for 8 weeks and 5 sessions per week for 2 to 6 minutes per session. Supplement group received 300 mg of Aloe vera daily for 8 weeks, five times a week. Data were analyzed using one-way ANOVA. Results: Eight weeks of high intensity interval training with Aloe vera supplementation resulted in a significant increase in adiponectin and insulin in diabetic male rats (P<0.05). But there was no significant difference in glucose and beta cell function (P>0.05). Conclusion: According to the findings of the present research, it seems that high intensity interval training along with Aloe vera supplementation may help to increase adiponectin and insulin and also improve diabetes control.

Background: Mesenchymal stem cells are pluripotent stromal cells which are capable of differentiating into different cell lines. Nowadays, umbilical cord Wharton’s jelly (UC-WJ) are increasingly used as sources of stem cells. Studies show that scaffolds can affect the differentiation of stem cells to different cells and cause higher cell viability and proliferation as well. The present study aimed to evaluate the adhesion and viability of WJ-MSCs to PLA/Wax scaffold. Materials and methods: PLA/Wax scaffold was prepared using electrospinning method. Adhesion and viability of MSCs on this scaffold was investigated using scanning electron microscope (SEM) and MTT assay respectively. Results: SEM results showed that the fibers were homogeneous, uniform, and free of beads with high quality property, and adding wax to PLA significantly reduced the diameter of the nanofibers. These studies confirmed that the cells were attached to the scaffold in large numbers and with appropriate size. The results of MTT show good biocompatibility of the scaffold made with the cells and a significant increase in the survival rate of mesenchymal cells was observed during the period. Conclusion: In conclusion, using PLA/Wax scaffold has promoted the attachment, survival and proliferation of the cells and has the potential to be an important candidate for developing the efficiency of 3D-cultures in order to cure diseases.

Background: Tuberculosis is a threat to public health. The epidemiology of tuberculosis can be effective in identifying the source of infection, the dominant circulating strains and achieving transmission pathways in the world. The aim of this study was to determine the genotype of Mycobacterium tuberculosis (M. tb) strains in patients referred to Pasteur Institute of Iran between 2018 and 2019. Materials and methods: In this study, 50 confirmed M. tb strains were evaluated. After M. tb strains identification and determining the drug susceptibility test, all strains were genotyped by MIRU-VNTR (Mycobacterial Interspersed Repetitive Unit Variable Number Tandem Repeat) method. Results: The most frequent genotype in all strains was CAS/Delhi (42%), followed by Haarlem (24%), NEW-1 (10%), LAM (8%), Beijing (8%), Cameroon (4%), EAI (% 2) and S (2%). Three clonal complexes and 44 singleton isolates were identified . Beijing genotype was the common genotype in MDR-TB strains. Also, QUB26 and QUB4156 loci had shown the highest of discriminative and allelic diversity. Conclusion: CAS/Delhi and Beijing genotypes were introduced as the dominant genotypes in drug sensitive and MDR strains, respectively.

Background: Pseudomonas aeruginosa is an opportunistic gram-negative bacterium that causes infections of the urinary tract, respiratory tract, skin inflammation, soft tissue infections, and a variety of systemic infections. Increased antibiotic resistance in Pseudomonas aeruginosa has led to its introduction as one of the most important nosocomial infections. Recently, carbon nanotubes are important and effective antibacterial agents. Materials and methods: Carbon nanotubes were prepared as carboxyl-functionalized nanofluids and then were evaluated on Pseudomonas aeruginosa to reduce antibiotic resistance. Results: It was observed that multi-walled carbon nanotubes had antimicrobial effects on Pseudomonas aeruginosa. Bacterial resistance to the antibiotic meropenem was also significantly reduced in the presence of nanofluids containing functionalized carbon nanotubes. Thus, by co-administration of functionalized carbon nanotubes and meropenem, in the nanofluid condition, a significant reduction in growth was observed. Conclusion: In the present study, using nanofluids containing functionalized carbon nanotubes and also increasing its stability, the antibiotic resistance of Pseudomonas aeruginosa was significantly reduced in lower dilutions than antibiotics alone. However, more specialized cellular and molecular research are needed to obtain more accurate results.

Background: Trimethyltin (TMT) is an organotin with selectively damage in the cerebral cortex and hippocampus which leads hyperactivity in prenatal exposure. The aim of this study was the evaluation of Ferulic acid (FER) effect on amelioration of motor and cognitive deficits in prenatal TMT-intoxication rat model. Materials and methods: In this experimental study, 30 Wistar pregnant rats were randomly divided into 5 groups, including control group, TMT+Saline group and TMT+FER25, TMT+FER50 and TMT+FER100 groups. TMT (9 mg/kg) were intraperitoneally injected to the pregnant rats on embryonic day (ED) 14. Ferulic acid groups were treated by 25, 50 and 100 mg/kg doses of Ferulic acid during ED12 to ED18. Open field test for evaluation of anxiety and locomotor activity, beam walking and grid walking test for assessment of motor learning and Y-maze for evaluation of working memory were used on postnatal day (PND) 30. The data were analyzed by ANOVA and Tukey post hoc. Results: Increased rates of anxietylike behaviors, decrease of motor learning and working memory were shown in TMT+Saline group compared to the control. Although, Ferulic acid treated groups were shown a significant amelioration in correct alteration behavior and motor learning with reduction of anxietylike behaviors (p˂0.05). Conclusion: TMT prenatal exposure impairs learning and attention in rats and Ferulic acid may reduce cognitive-behavioral deficits.

Background: This study aimed to examine the mediating role of attachment styles to parents and peers in predicting aggression and social self-efficacy among adolescents. Materials and methods: This was a descriptive-correlational (predictive) study that regarded as an applicable study in terms of its objective. The statistical population included all adolescents referred to healthcare centers in Zahedan whom based on the latest statistics, were more than 190 adolescents. Using Morgan’s table, the sample size was determined 122 people. A convenience sampling method was applied to select the sample and the measurement tools were the Armsden and Greeberg Inventory of Parent and Peer Attachment (1987), the Buss and Perry Aggression Questionnaire (1992), and the Connolly Scale of Social Self-Efficacy (1989). Research hypotheses were analyzed using the stepwise regression analysis via SPSS ver.22. Results: Among the components of attachment to peers and parents, in the first step, feeling alienated with peers explained 11% of the variance and, in the second step, feeling alienated with parents explained 18% of the variance in aggression among the adolescents at the confidence level of 0.99. Additionally, among the components of attachment to peers, only the component of communication with peers predicted 2.5% of the variance in social self-efficacy at confidence level of 0.95. Conclusion: Attachment to parents and peers is one of the important factors contributing to aggression and social self-efficacy among adolescents.
