Abstract
Introduction: Infertility could decrease the self-esteem of the infertile couples. Using the defensive style is one way to deal with stressful events. Therefore, the aim of this study was to investigate the role of self-esteem and defense mechanisms based on the cause of infertility.
Methods: In this cross-sectional study, 400 infertile couples referred to infertility center in Tehran, Iran. Participates classified in 4 groups for the cause of infertility: female, male, both and unknown. Data gathering tools in this study were demographic questionnaire, Rosenberg Self-Esteem Scale and Defense Styles Questionnaire (DSQ). Data were analyzed (SPSS 18 software) using paired t-test for comparison between the groups according to the cause of infertility and using regression analyses tests.
Results: The results of this study showed that men in female infertility group has significantly higher self –esteem than other groups (P<0.049). In couples, husbands with female and male factor showed more self-esteem than their wives (P< 0.001, P<0.008, respectively). In defense mechanisms, there was no difference between women, men, and couples. In this study, self-esteem showed a negative relationship with immature and neurotic defense mechanisms and a positive relationship with mature defense mechanism.
Conclusion: The findings of this study showed that women had higher levels of vulnerability than their husbands did even when they were not the cause of infertility so they have a low self-esteem. Therefore, it is suggested that infertile women receive more psychological counseling than men, and in order to facilitate the treatment of infertile couples and provide better services to improve marital relationships and solve their problems, differences between men and women about psychological issues should be considered.

Abstract
Introduction: Maxillary sinus drains through the primary maxillary ostium into the infundibulum, then flows through the hiatus semilunaris into the middle meatus and communicates with the nasal cavity. The maxillary sinus ostium is located approximately at the most superior part of the medial wall of the sinus. Accessory maxillary ostium (AMO) may play a role in sinusitis, but the effect of heredity or environment on the presence or absence of AMO is unknown.The aim of this study was to assess the primary and accessory maxillary ostium.
Methods: In this descriptive-cross-sectional study, 130 Cone Beam Computed Tomography scans (260 sinuses in total) from the maxilla of patients referred to the Department of Oral and Maxillofacial Radiology, School of Dentistry of Isfahan Azad University were examined in Isfahan City, Iran (in the year 2021-2022). Measurements were performed in the coronal section by On Demand 3D software. Statistical analysis was performed by T-Test, Exact fisher, Shapiro-Wilk and Spearman tests through SPSS statistics version 16.
Results: The mean diameter of primary maxillary ostium was 1.33 ± 0.45 on the right and 1.33 ± 0.5 on the left, respectively. AMO was observed in 64% of the left sinuses and 38.5% of the right sinuses. Increased sinus mucosal thickness was seen in 26% of the right sinuses and 28% of the left sinuses, and finally Mucous Retention Cyst in 9% of the right sinuses and 8% of left sinuses, respectively.
Conclusion: Primary maxillary ostium size was not statistically significant related to the variables of age, sex and the presence of AMO, but on the right side, the average primary maxillary ostium size is less if there is increase in the thickness of the sinus mucosa than when there is no increase in the thickness.

Abstract
Introduction: Shift work disorder (SWD) is a sleep disorder that affects the circadian rhythm and is characterized by symptoms such as excessive daytime sleepiness and insomnia. This condition can significantly increase the risk of accidents and diminish the overall quality of life for individuals affected by it. Therefore, using the four-question of shift work disorder questionnaire (SWDQ) can be useful for identifying people at risk of SWD. In this research, we evaluated the accuracy and consistency of the Persian adaptation of the SWDQ among female employees.
Methods: In this descriptive cross-sectional investigation, a sampling available method was employed to select employed women who were referred to Royan Institute, Arash Hospital, and Gynecological Office in Tehran. It was used translated and reverse translation methods for the questionnaire of SWDQ. Statistical analysis was performed by using the Statistical Package for the Social Sciences (SPSS version 16, Inc. Chicago, IL, USA).The tests used in this study were Cronbach's alpha, internal correlation, and confirmatory factor analysis.
Results: In terms of content validity rate (CVR) with an average of 70% (questions 80%, 80%, 60% and 60%, respectively) and content validity index (CVI) with an average of 87.5% (questions 100%, 90%, 80% and 80%, respectively) was acceptable. The internal homogeneity of the SWD questionnaire with Cronbach's alpha was 63.4% and deleting each of the four items of the questionnaire reduced it. Moreover, the range of total correlated changes for the questionnaire was from 0.339 to 0.488, which was more than the minimum of 0.3.
Conclusion: Overall, the validity and reliability of the Persian version of SWDQ (the four-item) have acceptable.

Abstract
Introduction: Vincristine (VIN) is a broad-spectrum anticancer drug used to treat various cancers. Resveratrol (Res) is a natural polyphenol found in numerous plant sources. Many studies have reported anti-inflammatory and antioxidative effects of resveratrol. In this study, the effect of resveratrol on kidney damage caused by vincristine in female mice has been investigated.
Methods: In this study, 36 female mice weighing 25-30 grams were randomly divided into four groups (n=9): 1) Control group, 2) Vin- group, 3) Vin-Res group and 4) Res group. The mice received vincristine at 3 mg/kg once a week for 4 weeks and resveratrol at 30 mg/kg daily for 28 days through gavage. At the end of the study, the fat peroxidation index (MDA), total antioxidant capacity (TAC), and the activities of the antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPX) in kidney tissue were measured. Data were presented as mean ± standard deviation, and the significant differences among groups were analyzed using SPSS16, one-way ANOVA, and Tukey's post hoc test.
Results: The findings indicated that in the vincristine group, levels serum of urea, creatinine, and MDA in kidney tissue were increased significantly compared to the control group (P=0.001).the TAC level and the activity level of GPX (P=0.001) and SOD (P=0.009) enzymes in the kidney tissue were significantly decreased in the vincristine group when compared to the control group (P=0.001). Conclusion: The results of this study showed that the protective effects of resveratrol were probably attributed to its antioxidant properties and that it could reduce the kidney damage induced by vincristine.
