    ABSTRACT This is a comparative study that aims at comparing the extent of self-concept and compatibility among single and divorced women in Bandar Abbas (Mostly between 25 to 35 years old). According to this research, the method used is descriptive and of causalcomparative. The study population included all single girls over 25 years, living in the city of Bandar Abbas. All divorced women had their divorce decree issued 12 month before the study. The study samples included 130 people who responded to Roger's Self-Concept and Bell's Compatibility questionnaire. The data for this study were analysed using SPSS software. Results from data analysis showed that self-concept of divorcees and singles is not much different. The results also showed that the compatibility of divorced and single individuals is not the same and also reveals that the compatibility of single girls is more than divorced women. It can be concluded that the "compatibility variable" has little predictive power compared to "self-concept variable"

    BackgroundDisorders affecting the nervous system are diverse and include neurodevelopmental disorders, late-life neurodegeneration, and newly emergent conditions, such as cognitive impairment following COVID-19. Previous publications from the Global Burden of Disease, Injuries, and Risk Factor Study estimated the burden of 15 neurological conditions in 2015 and 2016, but these analyses did not include neurodevelopmental disorders, as defined by the International Classification of Diseases (ICD)-11, or a subset of cases of congenital, neonatal, and infectious conditions that cause neurological damage. Here, we estimate nervous system health loss caused by 37 unique conditions and their associated risk factors globally, regionally, and nationally from 1990 to 2021.MethodsWe estimated mortality, prevalence, years lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life-years (DALYs), with corresponding 95% uncertainty intervals (UIs), by age and sex in 204 countries and territories, from 1990 to 2021. We included morbidity and deaths due to neurological conditions, for which health loss is directly due to damage to the CNS or peripheral nervous system. We also isolated neurological health loss from conditions for which nervous system morbidity is a consequence, but not the primary feature, including a subset of congenital conditions (ie, chromosomal anomalies and congenital birth defects), neonatal conditions (ie, jaundice, preterm birth, and sepsis), infectious diseases (ie, COVID-19, cystic echinococcosis, malaria, syphilis, and Zika virus disease), and diabetic neuropathy. By conducting a sequela-level analysis of the health outcomes for these conditions, only cases where nervous system damage occurred were included, and YLDs were recalculated to isolate the non-fatal burden directly attributable to nervous system health loss. A comorbidity correction was used to calculate total prevalence of all conditions that affect the nervous system combined.FindingsGlobally, the 37 conditions affecting the nervous system were collectively ranked as the leading group cause of DALYs in 2021 (443 million, 95% UI 378–521), affecting 3·40 billion (3·20–3·62) individuals (43·1%, 40·5–45·9 of the global population); global DALY counts attributed to these conditions increased by 18·2% (8·7–26·7) between 1990 and 2021. Age-standardised rates of deaths per 100 000 people attributed to these conditions decreased from 1990 to 2021 by 33·6% (27·6–38·8), and age-standardised rates of DALYs attributed to these conditions decreased by 27·0% (21·5–32·4). Age-standardised prevalence was almost stable, with a change of 1·5% (0·7–2·4). The ten conditions with the highest age-standardised DALYs in 2021 were stroke, neonatal encephalopathy, migraine, Alzheimer's disease and other dementias, diabetic neuropathy, meningitis, epilepsy, neurological complications due to preterm birth, autism spectrum disorder, and nervous system cancer.InterpretationAs the leading cause of overall disease burden in the world, with increasing global DALY counts, effective prevention, treatment, and rehabilitation strategies for disorders affecting the nervous system are needed

    Nitrate is one of the most important groundwater pollutants with such different sources as chemical fertilizers, pesticides, or domestic and industrial wastewater. In this research, the optimal operation of groundwater wells in aquifers with nitrate pollution is investigated using simulation and optimization techniques. For the simulation part, an artificial neural network (ANN) model is developed, and for the optimization model, the particle swarm optimization (PSO) is used. Considering the high nitrate concentration in Karaj area and its increase in recent years, the northern part of this aquifer is selected as a case study to apply the proposed methodology. A seasonal ANN model is developed with input layers including well discharge in the current and previous seasons, nitrate concentration in the previous season, aquifer thickness, and well coordinates, all selected based on sensitivity analysis. The results of PSO algorithm shows that nitrate concentration can be controlled by increasing or decreasing well discharge in different zones. Therefore, it is possible to reduce nitrate concentration in critical areas by changing the spatial distribution of groundwater extractions in different zones keeping the total discharge constant

    Introduction and Aims: Fruits and vegetables as parts of healthy food system are recommend. Individuals who have high consumption of fruits and vegetables, less likely to involve overweight and danger of encountering to cordial disease and special type of cancer is reduced. Consumption of fruit and vegetable lead to safe from type 2 diabetes ,brain strike, long term pulmonary diseases, eye cataract, blood pressure and intestine disease.Materials and Methods: This cross-sectional analytic study implemented on 200 citizen in Ilam by random sampling. Data gathering tools is questionnaire include constructions of developed planned behavior theory.Results: Attitudes, habits, and intention have impact directly on consumption of fruit and vegetables. However attitude and habits affected consumption of fruit and vegetables thereby intention. Based on general effect of variables after habits, attitude was the second factor that predict the consumption. Mental norms have no significant direct effect on consumption of fruit and vegetables.Conclusion: Hygienic theories such as planned behavior theory, can help to predicting and planning healthy behaviors. Planned behavior theory can be used for planning and intervening in order to preventing of disease.* Corresponding Author: Ilam University, Faculty of Management.Email: [email protected]

    Introduction: Stroke is one of the most common causes of death worldwide. Inflammation and apoptosis play an important role in the cascade of ischemic stroke. Aim: The aim of the present study was to evaluate the pretreatment effects of Lamium album (L. album) extract on caspase-3 and cyclooxygenase-2 (COX-2) expression, infarct volume, and neurological deficit score in a rat model of middle cerebral artery occlusion (MCAO). Materials and methods: Wistar male rats were randomly divided into three groups: 1) MCAO group (1 h after MCAO, reperfusion was allowed for 24 h by retracting the thread); 2) L. album + MCAO group [receiving L. album extract (100 mg/kg via intraperitoneal) for a week before MCAO]; 3) sham group. The expression level of caspase-3 and COX-2 in the core, penumbra, and subcortex regions was measured by real time-PCR technique. Infarct volume and neurological deficit score were also assessed. Results: The mRNA expression of caspase-3 in the core, penumbra, and subcortex regions in L. album group was significantly reduced compared to MCAO group (p<0.05). Expression level of COX-2 in the subcortex of the rats exposed to L. album was statistically decreased relative to MCAO group (p<0.05). Infarct volume in the core, penumbra, and subcortex was significantly reduced in the L. album group compared with MCAO group (p<0.001, p<0.001, p<0.05, respectively). Neurological deficit score was remarkably decreased in the L. album group in comparison with the MCAO group (p<0.05). Conclusions: It appears that pretreatment with L. album extract may attenuate brain tissue damage after ischemic stroke. The potential protective effects of this plant extract against this condition might be in part attributed to its anti-inflammatory and anti-apoptotic activities
