Abstract
Introduction: In diabetes mellitus the increase of AgII (Angiotensin II), IGF-1(insulin like growth factor-1) and growth hormone induce kidney lesions especially changes in content and thickness of GBM and widening and fusion of podocyte pedicles. In this research for the first time the combination of Losartan (AT1 receptor blocker) and Octreotide (Somatostatin analogue) were used in order to prevent glomerular epithelial lesions.
Materials & Methods: In this experimental study 15 male rats (2 months age) were uninephrectomised from left flank and divided in 5 groups (3 per group). 7 days later diabetes was induced in 2th, 3th, 4th and 5th group by Alloxan (120mg/kg) subcutaneously. 5 days after diabetes induction, the third group received Losartan (5mg/kg/day) orally, 4th group Octretide (10 ŭg/day) subcutaneously and 5th group both two drugs with the mentioned doses for 8 weeks. The 2th group was served as diabetic non treatment group. Kidneys of all groups were fixed by perfusion technique. After second fixation of 1 mm3 cortex parts in Osmium Tetroxide, they were processed in TAAB812 resin for embedding. Thin sections (600 nm thickness) were prepared and investigated by transmission electron microscope qualitatively.
Results: Losartan inhibited fusion and thickening of podocyte pedicles but in some cases couldn,t maintain the 3 layer form of GBM. Octreotide had little effect on inhibition of fusion and thickening of podocyte pedicles and no effect in 3 layer form maintaining of GBM. Combined therapy inhibited fusion and thickening of podocyte pedicles and maintained 3 layer form of GBM but in some cases the lamina rara near endothelium was not seen.
Conclusion: Octreotide have little effect on prevention of glomerular epithelium lesions. However Losartan could prevent glomerular epithelium lesions well, but combined drug therapy showed better results comparing Losartan.

Abstract
Background and Aim: The long noncoding RNAs (lncRNAs) is an important type of RNAs that can regulate gene expression and, therefore, are involved in the development of various cancers. The genome-wide association study (GWAS) is used to identify phenotype-related loci within non-coding regions. However, the biological functions and exact relationships between phenotype-related loci and lncRNAs have not fully been identified. No study was found on the relationship between rs8506C>T polymorphisms in the lincRNA-NR_024015 exon and breast cancer susceptibility and clinical factors. Therefore, the present study aimed to evaluate the effect of polymorphism rs8506C>T on the breast cancer risk.
Methods & Materials: In this case-control study, participants were 120 patients with breast cancer, 120 healthy controls. The genetic variant was genotyped by using the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR–RFLP) method. Interactions between the polymorphism and clinical factors were further evaluated, and Odds Ratio (OR) was measured for risk assessment.
Ethical Considerations: This study has been approved by the Research Ethics Committee at Shahrekord University of Medical Sciences (code:????) .
Results: There was a correlation between rs8506 C>T polymorphism and breast cancer risk in the dominant model (CC and CT+TT genotypes; P=0.027; OR=1.84; 95% CI: 1.067‐3.201). In the co-dominant model, CT genotype had a statistically significant association with breast cancer risk (P=0.038). Subjects with T allele in the rs8506 polymorphism had an increased risk of breast cancer (OR=1.69; 95% CI: 1.047-2.736; P=0.031). No relationship between rs8506 polymorphism and clinical factors including metastasis, tumor grade, and Human Epidermal Growth Factor Receptor 2 (HER2) status was observed.
Conclusion: Genetic variant rs8506 C>T polymorphism in the lincRNA-NR_024015 exon may contribute to the breast cancer risk. Allele T in this variant confers an increased risk of breast cancer. Further functional analyses are required to detect the detailed mechanism underlying the observed association.

Abstract
Background and Aim: Ankle injuries are among the most common musculoskeletal injuries in sports, accounting for 10% to 15% of all injuries. Since controlling pain and inflammation in ankle sprains is one of the main goals of treatment, we decided to compare the therapeutic effects of Cheleh daghi Herbal ointment with a common therapeutic gel such as piroxicam.
Methods & Materials: This study was performed as a double-blinded clinical trial for 6 months from January 2019 to August 2019. After referral, all patients completed the consent form, and the patient's details and study variables were recorded by the evaluator in the research form. To measure joint inflammation, we measured the ankle with a meter tape in the ankle area (cm) and recorded. A goniometer was also used to measure the degree of ankle movements. The symptoms of ankle ecchymosis were also checked by physical examination and observation and recorded in the checklist. Statistical analysis was performed in SPSS V. 18 using statistical tests (the Mann-Whitney U test, the Chi-square, and the independent t-test).
Ethical Considerations: The Research Ethics Committee of Arak University of Medical Sciences approved the study (Code: IR.ARAKMU.REC.1396.55) and registered by the Clinical Trial (Code: IRCT2017071720258N53).
Results: The Mean±SD age in the control group was 34.2±8.6 years, and in the case group was 35.4±8.9 years. There was no statistically significant difference according to the Mann-Whitney U test (P<0.05). Also, the Mean±SD height in the control group was 1.7±0.12 m and in the case group was 1.72±0.11 m. The results also showed a statistically significant difference between the two groups studied before and after the intervention regarding the mean indicators of pain, swelling, and inflammation around the joints (P<0.05).
Conclusion: The results of our study showed that Cheleh daghi Herbal ointment for 3 weeks could be more effective in reducing local pain and inflammation than piroxicam gel treatment.

Abstract
Introduction: Delinquency is a serious challenge for teenagers and has significant negative social effects. The main goal of this research was to find out the structural equation modeling of extraversion and delinquent behavior disorder: the mediating role of moral intelligence among the juveniles of Kerman Correctional Center.
Methods: This was a descriptive correlational research of structural equation model type. The statistical population of this research was made up of 80 juveniles of Kerman Correctional Center, who were selected and studied by simple random sampling using Morgan's table. To collect information, Hans Eysenck's (1963) Personality Type Questionnaire, Goodman's Conduct Disorder Questionnaire (1997), Aiti Juvenile Delinquency Questionnaire (2013) and Link and Keel's Moral Intelligence Questionnaire (2005) were used. Descriptive and inferential statistics (structural equation modeling) were used for data analysis through SPSS-28 and Smart PLS-3 software.
Results: The results of this research showed that there is a direct and positive relationship between extraversion and juvenile delinquency. There is a significant direct and positive relationship between conduct disorder and juvenile delinquency. There is a direct and positive relationship between extroversion and moral intelligence of teenagers. There is a significant direct and negative relationship between conduct disorder and moral intelligence of adolescents. There is a direct negative relationship between moral intelligence and delinquency. There was no relationship between extraversion and juvenile delinquency as a mediator of moral intelligence. There was no relationship between conduct disorder and juvenile delinquency with the mediating role of moral intelligence.
Conclusions: According to the results, it can be acknowledged that moral intelligence is an effective component of delinquency affected by extroversion and behavior disorder in teenagers. Therefore, education and training programs should be implemented to strengthen moral intelligence in schools and families, because these programs can strengthen moral skills and moral decision-making power in teenagers and help reduce behavioral disorders and, as a result, delinquency.
