National and sub-national age-sex specific and cause-specific mortality and disability-adjusted life years (DALYs) attributable to household air pollution from solid cookfuel use (HAP) in Iran, 1990–2013

National and sub-national mortality, years of life lost due to premature mortality (YLLs), years lived with disability (YLDs) and disability-adjusted life years (DALYs) for household air pollution from solid cookfuel use (HAP) in Iran, 1990–2013 were estimated based on the Global Burden of Disease Study 2013 (GBD 2013). The burden of disease attributable to HAP was quantified by the comparative risk assessment method using four inputs: (1) exposure to HAP, (2) the theoretical minimum risk exposure level (TMREL), (3) exposure-response relationships of related causes (4) disease burden of related causes. All across the country, solid fuel use decreased from 5.26% in 1990 to 0.15% in 2013. The drastic reduction of solid fuel use leaded to DALYs attributable to HAP fell by 97.8% (95% uncertainty interval 97.7–98.0%) from 87,433 (51072–144303) in 1990 to 1889 (1016–3247) in 2013. Proportion of YLLs in DALYs from HAP decreased from 95.7% in 1990 to 86.6% in 2013. Contribution of causes in the attributable DALYs was variable during the study period and in 2013 was in the following order: ischemic heart disease for 43.4%, chronic obstructive pulmonary disease for 24.7%, hemorrhagic stroke for 9.7%, lower respiratory infections for 9.3%, ischemic stroke for 7.8%, lung cancer for 3.4% and cataract for 1.8%. Based on the Gini coefficient, the spatial inequality of the disease burden from HAP increased during the study period. The remained burden of disease was relatively scarce and it mainly occurred in seven southern provinces. Further reduction of the disease burden from HAP as well as compensation of the increasing spatial inequality in Iran could be attained through an especial plan for providing cleaner fuels in the southern provinces

The study of the relationship between organizational structure and psychological empowerment among the staffs in Ministry of Economic Affairs and Finance

The present paper has been conducted with the aim of studying the relationship between organizational structure and psychological empowerment of staff of the Ministry of Economic Affairs and Finance. This research is applied and is survey study from conduct point of view. Research population includes all the staff, experts and managers of Financial Supervision Department and Treasury of the whole country of the Ministry of Economic Affairs and Finance which is a total number of 537 persons. For this purpose we have used closed questionnaires in the form of five options (standard questionnaire of Robins’ organizational structure which has three dimensions of formality, complexity and focus and standard questionnaire of Whetten and Cameron’s psychological empowerment which has 5 dimensions of trust, meaningfulness, effectiveness, self-efficiency, and self-determination). The size of the sample is 224 individuals of staff, experts and managers which have been selected with the use of stratified sampling. For analyzing the obtained data descriptive statistics (frequency table) and inferential statistics (Pearson’s correlation coefficient test) have been used which the results indicate that there is significant and negative relationship between organizational structure and three dimensions of “formality”, “complexity”, “focus” with psychological empowerment variable. Dimension of focus has the highest significance (first rank) among other dimensions of organizational structure variable and also self-determination has the highest importance (first rank) among the dimensions of psychological empowerment

The effect of Phoenix dactylifera pollen on the expression of NRF2, SOD2, CAT, and GPX4 genes, and sperm parameters of fertile and infertile men: A controlled clinical trial

Background: Oxidative stress is caused by the imbalance occurring between the creation and clearance of the reactive oxygen species (ROS), which is responsible for 30–40% of male infertility. The positive impact of phoenix dactylifera pollen (Date palm pollen, DPP) on the improvement of sperm parameters has been well documented in animal models. Objective: For evaluating the effect(s) of DPP on sperm parameters, ROS levels, expression of antioxidant genes, and activity of antioxidant enzymes of infertile men. Materials and Methods: In this controlled clinical trial, a total of 60 male case with infertility and 20 normospermic fertile men were recruited. Before and after the treatment with DPP, the case were administered 400 mg/kg of gelatinous capsules daily for 30 consecutive days and semen samples were taken. Quantitative real-time polymerase chain reaction was applied for the evaluation of the mRNA expression levels of Nuclear factor erythroid 2-related factor 2(NRF2), superoxide dismutase (SOD2), glutathione peroxidase 4(GPX4), and catalase (CAT) genes. Results: The mRNA expression levels of NRF2, SOD2, GPX4, and CAT (p < 0.05 for all) and significantly increased after treatment with DPP. The increased expressions of all antioxidant genes and enzymes significantly correlated with improvement in semen parameters including count (p = 0.01), motility (p = 0.05), and morphology (p = 0.01) of sperm. A significant correlation between the alteration of SOD2 gene expression and SOD activity, GPX4 and GPX, and CAT were also observed (p = 0.05). Conclusion: DPP can increase the expressions of NRF2, GPX4, SOD2, and CAT genes and also improve the semen quality in infertile men. Key words: DPP, Male infertility, SOD2, NRF2, GPX4, CAT, ROS, Spermatozoa
