Abstract
Background and Aim: Non-alcoholic fatty liver disease is a type of accumulation of fat in the liver cells. Moreover, portulaca oleracea has hypolipidemic properties. Accordingly, the present study aimed to investigate the effect of a combination of training and portulaca oleracea supplementation on plasma lipid profile and liver ultrasound in obese women with nonalcoholic fatty liver.
Methods & Materials: The study population consisted of 40 to 60-year-old obese women with non-alcoholic fatty liver disease. In total, 40 obese women with nonalcoholic fatty liver disease were randomly selected and divided into 4 groups. The study groups included training (n=10), training + supplementation (n=10), placebo (n=10) and supplementation (n=10). Before and after the intervention, sonography of the liver and blood tests were performed. The Paired Samples t-test and Analysis of Variance (ANOVA) were used to analyze the obtained data. The significance level was set at P<0.05.
Ethical Considerations: This study was approved by the Research Ethics Committee of Islamic Azad University, Rasht Branch, Iran (code: IR. IAU.RASHT.REC. 1397. 034). Moreover, it was registered at the Iranian Registry of Clinical Trials (IRCT) (code: IRCT201903090429871).
Results: The obtained data suggested that 12 weeks of portulaca oleracea supplementation and combination training significantly decreased the plasma concentrations of cholesterol (P=0.001), triglyceride (P=0.00), LDL (P=0.00), and significantly increased serum HDL levels (P=0.00) in the exercise + supplement, supplement, and exercise groups (P<0.05). Liver ultrasound data also improved in the exercise + supplement (P=0.02), and exercise (P=0.00) groups.
Conclusion: Portulaca oleracea supplementation with combination exercises could be effective in reducing plasma lipids and improving liver ultrasound in obese women with nonalcoholic fatty liver.

Abstract
Background and Aim: There exists increased demineralization risk of enamel adjacent to fixed orthodontic attachments by cariogenic bacterias (e.g., Streptpcoccus mutans, Streptpcoccus sobrinus) and inadequate data about commonly used orthodontic cements. Thus, we evaluated the antibacterial effects of three common domestic and foreign orthodontic cements (Glass ionomer, Zinc phosphate, & polycarboxylate) on two cariogenic pathogens (S. mutans & S. sobrinus).
Methods & Materials: In this laboratory study, after culturing two standard strains of Streptococcus mutans and Subrinus bacteria and concentrating and diluting them, a direct contact test was used to evaluate the antibacterial properties of types of cement. The study groups (n=5) included the following: three types of glass ionomer resilience cement, Hoffman’s zinc phosphate and Hoffman’s polycarboxylate, and three glass ionomer cement, zinc phosphate, and carboxylate from Aria Dent factory in Iran. The acquired data were analyzed using SPSS v. 17.
Ethical Considerations: The present study was approved by Babol University of Medical Sciences (Code: MUBABOL.REC.1391.7).Results: In both types of culture media, containing Streptococcus mutans and Streptococcus subrinus bacteria, there was a significant difference between culture media containing 3 groups of cements respecting bacterial growth inhibition zone (P<0.001). In general, The mean diameter of the inhibition zone was greater in Iranian polycarboxylate, compared to its foreign counterpart (P<0.001).
Results: Regarding to zone of inhibition, there was statistically significant difference between three tested cements in both S.mutans and S.sobrinus culturing media (P<0.001). The mean diameter of inhibition zone was greater for Iranian polycarboxylate compared to its foreign counterpart (P<0.001).
Conclusion: Glass ionomer cement demonstrated better antibacterial effect compared to zinc phosphate and polycarboxylate cements. There was also greater antibacterial effect of three tested cements on S.sobrinus than S.mutans. Iranian polycarboxylate showed stronger inhibition on both mentioned bacterias compared to the foreign one.

Abstract
Introduction: Glyphosate is the most popular broad-spectrum herbicide globally due to the growing demand for glyphosate-resistant crops. Glyphosate exhibits harmful properties, including cytotoxicity, neurotoxicity, and reproductive toxicity. This study aimed to investigate the detrimental effects of glyphosate on ovarian histopathology in mice and the in vitro maturation (IVM) of oocytes following superovulation.
Methods: In this study, thirty-two female NMRI mice were randomly divided into the following groups: control, glyphosate, superovulation, and superovulation-glyphosate. Animals received glyphosate (0.5%) continuously through drinking water for three weeks. HMG and HCG were used to induce superovulation. Oocytes were collected from the ampulla, and the quantity and quality of oocytes were analyzed. Then, in vitro maturation (IVM) of oocytes was performed. At the end of the study, ovarian histopathology was analyzed.
Results: Compared to the control group, the glyphosate-treated group exhibited a significant decrease in secondary and Graafian follicles while demonstrating a concomitant increase in atretic follicles (P < 0.05). Additionally, the superovulation-glyphosate group showed fewer germinal vesicle breakdown (GVBD) and MII oocytes than the superovulation group. In the superovulation-glyphosate group, there was a notable reduction in GVBD and MII oocytes following in vitro maturation (IVM).
Conclusions: Glyphosate has the potential to damage ovarian tissue and adversely affect IVM and oogenesis.

Abstract
Good governance, as one of the fundamental concepts in managing health systems, plays a critical role in improving efficiency, effectiveness, and equity in delivering healthcare services. Emphasizing principles such as transparency, accountability, participation, and rule of law, good governance has been regarded as a framework for enhancing policymaking and management within health systems.
Objective: This study aimed to design and propose a model of good governance in the health system using a combined approach of thematic analysis and the partial least squares (PLS) method.
Methodology: The research employed both qualitative and quantitative methods. In the qualitative phase, the research population consisted of managers, experts in health and medical sciences, senior officials from the Ministry of Health and Medical Education, and academic scholars. Seventeen participants were selected using purposive and snowball sampling methods until theoretical saturation was achieved. In the quantitative phase, the PLS method was utilized to fit the proposed model. The statistical population included all health and medical professionals in Iran. Based on Cochran’s formula, the minimum sample size was calculated to be 384 participants.
Findings: The results of thematic analysis in the qualitative phase, followed by model fitting in the quantitative phase, revealed that the final model of good governance in the health system consists of seven main dimensions: effectiveness, efficiency, equity, transparency and accountability, participation, rule of law, and leadership. Each dimension was further divided into specific components, confirming their significance in strengthening good governance.
Conclusion: This study presents a comprehensive model of good governance for the health system, offering a framework to enhance policymaking, management, and performance in this field. The proposed model can serve as a tool for strategic decision-making and improving managerial structures.
