In this study, we investigated the main constituent, the predominant class and biological activity of the essential oil extracted from the leaves of Pimenta dioica and the pattern of the major constituent against larvae in the third stage of Aedes aegypti. For this reason, we extracted the oil by hydrodistillation, identified its components by gas chromatography coupled with mass spectrometry (GC/MS) and calculated the lethal concentration (LC50) of the larvicidal activity using the Reed-Muench method. The results show that the oil consists mainly of eugenol, in which the phenylpropanoid class predominated and the lethal concentration, LC50, was 38.86 μg mL-1at a confidence level of 2.25 μg mL-1, while the eugenol standard presented LC5079.75 μg mL-1at a confidence level of 2.10 μg mL-1. Given the facts, we conclude that the oil is more active than the standard and that it has the potential to replace chemical larvicides.

Background: Given the rising rate of infertility, the prevalence of mental health disorders in infertile couples is undeniable. The present study aimed to investigate the effects of Integrative Behavioral Couple Therapy (IBCT) on infertility self-efficacy, dyadic adjustment, and sexual satisfaction in infertile couples. Methods: The present single-case experimental study used a multiple-baseline design. The statistical population of the study included all infertile couples referring to infertility centers in Ahvaz City, Iran, in 2019. The research instruments included the Infertility Self-Efficacy Scale (ISE), the Dyadic Adjustment Scale (DAS), and the Sexual Satisfaction Questionnaire (SSQ). Following a diagnostic interview, 3 couples were selected using the convenience sampling technique. Integrative behavioral couple therapy was conducted in twelve 120-minute sessions for the intervention group. The second couple entered the study in the second session of the first couple; the third couple enrolled the treatment plan in the third session of the first couple and the second session of the second couple. All questionnaires were completed in the first, third, sixth, eighth, and tenth sessions; the study participants were followed up and re-assessed two months later. The collected data were analyzed in SPSS using chart analysis, reliable change index, and significance statistics. Results: The provided IBCT increased infertility self-efficacy (39.04%), dyadic adjustment (25.91%), and sexual satisfaction (55.01%) in infertile couples. Besides, the improvement lasted throughout the follow-up which indicated the effectiveness of IBCT on infertility self-efficiency, dyadic adjustment, and sexual satisfaction in the study subjects. Conclusion: IBCT can be effective in improving personal and marital variables in infertile couples with infertility problems in addition to their marital problems.

This study aims to identify the determinants of non-performing financing (NPF) in Islamic banks in Indonesia. The study objects are the Islamic banking industry during the first quarter of 2008 until the third quarter of 2019. The variables in this study are inflation, growth of Gross Domestic Product (PDB), and Bank Indonesia rate. The statistic method used is the Vector Error Correction Model (VECM). The result shows that inflation shock significantly affects the trend of NPF, while others do not give significant effect to NPF of Islamic Banking.
