The GC and GC/MS analysis of aerial parts of Ocimum gratissimum grown in Fars Province, southwestern Iran showed 51 constituents in volatile oil. Total percentage of identified constituents in the essential oil was equal to 99.05. The main components were linalool (32.2%), 1,8-cineole (15.57%), geraniol (14.7%) and epi-α-cadinol (5.5%). The essential oil yield was equal to 2.1%. The experiment continued using methanolic and hydromethanolic extracts of O. gratissimum to determine phenolic acid profiles as well as, antioxidant activity, total phenolic, and total flavonoid contents. Results showed total flavonoid contents of 151.90 and 15.77 μg QE mg−1 and phenolic contents of 63.05 and 74.59 μg GAE mg−1 for methanolic and hydromethanolic extracts, respectively. The IC50 values of the extracts were also reported as 714.49 for methanolic and 8724.39 μg mL−1 for hydromethanolic extracts, respectively. HPLC chromatograms showed the presence of 4.45 μg mg−1 DW of rosmarinic acid, 5.00 μg mg−1 DW of catechin, 3.30 μg mg−1 DW of gallic acid, and 2.47 μg mg−1 DW of sinapic acid for hydromethanolic extracts. The main phenolic acids were catechin (0.27 μg mg−1 DW), rosmarinic acid (0.1 μg mg−1 DW), sinapic acid (0.37 μg mg−1 DW), and eugenol (0.26 μg mg−1 DW) for methanolic extracts. All parameters showed significant differences in these extracts, while TPC presented a remarkable significant inverse relationship with TFC, FC, and anthocyanin at a significance level of 0.01, and a significant positive relationship was also reported between TFC and FC at a significance level of 0.01.

Purpose: Paying attention to the psychological characteristics of soldiers is a matter of concern for planners and senior commanders. Therefore, this study was conducted to investigate the mediating role of personality traits in the relationship between psychological empowerment and mental health in soldiers stationed in the Kerman Province barracks.In this cross-sectional study, 604 soldiers serving in Kerman Province barracks in the year 2021 were examined. The soldiers were selected from a cluster sampling of two barracks. Data were collected using a demographic information checklist, the Sportzier Psychological Empowerment Questionnaire (PEQ), the General Health Questionnaire (GHQ), and the NEO Personality traits (NEO). Pearson’s correlation coefficient and structural equation modeling were used for data analysis. The Judd and Kenny’s framework was also employed to investigate the mediating role.Of these individuals, 390 (46.6%) had completed their military training, while 433 (71.7%) were single. The correlation between PEQ and GHQ was inverse and non-significant (P = 0.348), between PEQ and NEO was direct and significant (P = 0.002), and between NEO and GHQ was inverse and significant (P < 0.001). In the structural equation model, the PEQ variable had a significant impact on NEO (P = 0.002), but it did not significantly affect the GHQ variable (P = 0.850). The NEO variable also had a significant impact on GHQ.The NEO variable has a full mediation effect on the relationship between PEQ and GHQ. Therefore, the use of psychologists and clinical physicians for appropriate interventions to enhance mental health, such as education, counseling, and psychotherapy, appears to be necessary.Method: Paying attention to the psychological characteristics of soldiers is a matter of concern for planners and senior commanders.

Climate Change Adaptation (CCA) is a complex, multi-disciplinary, and culture-dependent concept. This study aims to explore a conceptual definition, the subjective framework of CCA including its domains, attributes, and consequences. The approach of qualitative conventional content analysis was considered for the explanation of the subjective concept, and at the same time as the collection process, data analysis was performed using Zhang and Wildemuth's method. The interview method was semi-structured and sampling was targeted and with maximum diversity. The interview was conducted with 22 qualified experts. The accuracy and validity of the data were ensured using Guba and Lincoln scientific accuracy criteria. Six main categories including "sustainability, productivity, stability, empowerment, transformation, and flexibility" were conceptualized in the theme of adaptation characteristics. "Sustainable development, life improvement, response coordination and integration, creativity and innovation, resilience promotion, vulnerability reduction, effective management, and independence" were the main categories in the theme of the adaptation consequences. According to the results, the following conceptual-functional definition can be presented for adaptation to climate change: "CCA refers to the ability of system instability, sustainability, empowerment, productivity, flexibility, and transformation to climate change through the optimal use of resources, resistance, and coping, capacity building and opportunity creation". This definition is conceptual, it means that includes the main features of climate-adaptation and is also functional that is, includes adaptation strategies for climate change.

In recent years, climate change has been one of the most complicated problems that human being has faced. Climate change adaptation (CCA) is considered to be an important component of risk management. In order to achieve adaptation, it is necessary to determine the indicators influencing adaptation in each community and this requires measurement and standard tools. The aim of this study is to determine and categorize the indicators of CCA. International electronic databases including Science Direct, Web of Science, Scopus, Google Scholar were investigated for only articles published in English language. In addition, Iranian databases including Irandoc, SID, and Magiran were investigated. There was no limitation on the methods of studies. Furthermore, snowball method was used for finding more articles while the ProQuest database was searched for related dissertations. The published documents from 1990 to November 2017 were gathered in this study. Out of 4439 publications initially search, 152 full texts were investigated. Finally, a total of 45 potentially relevant citations were included for full text review; in addition, fourteen other sources were investigated. Using snowball method, we found 24 other articles that were included in our final result. From the searches, 176 indicators were identified, while seven main domains were mentioned. Since in the articles, domains of adaptation are not in the form of a model, it is better to focus on this issue in the future and it seems that prioritizing and weighting domains in adaptation in different communities with different needs are an important issue.

This study was conducted to investigate the effects of salicylic acid (SA) treatments on chlorophyll (Chl) degradation and postharvest quality of two lime (‘Persian lime’ and ‘Tahiti’) cultivars during cold storage. SA at 0, 0.5, 1 and 2 mM were applied to fruit by vacuum infiltration at 30.55 kPa for 7 min and afterward stored at 4 °C, and 85% RH for 60 days, then kept at 20 °C for 2 days as a simulated shelf life. Postharvest SA application effectively maintained greater fruit firmness and lessened weight loss during cold storage. The results displayed that SA treatments efficiently delayed the reduction of the Chl a contents and hue values. During cold storage, ascorbic acid content, antioxidant activity, and total phenolic content were greater in SA treated limes than the control. SA treated limes had the highest titratable acidity (TA), whereas soluble solids concentration (SSC), pH, and SSC/TA ratios of control fruit were greatest. Altogether, SA application by vacuum infiltration could be an effective and simple method for maintaining postharvest quality of limes during cold storage without chilling injury symptom.

In a pot experiment, essential oil composition, extract polyphenolic content and antioxidant activity of Pimpinella anisum L. seeds (aniseed) treated with 5-aminolevulinic acid (5-ALA) (0.1 and 0.2% w/v) were investigated. In all living organisms, the compound 5-ALA is natural and has various effects on plants physiology. 5-ALA has attracted increasing attention as a plant growth regulator (PGR) owing to its nontoxicity to humans, crops and animals. The essential oil constituents in the aniseed are significantly changed by 5-ALA foliar application. Sesquiterpenes, particularly β-bisabolene, (447.51 and 424.39 g kg−1) were nominated as the predominant fundamental class of essential oil components under 5-ALA treatments. Also, after foliar application of 5-ALA at the level of 0.2% w/v, polyphenolic contents as well as the antioxidant activity of aniseeds extract increased. The highest level of chlorogenic acid (0.47 mg g−1) as the main phenolic compound was obtained from the 5-ALA (0.2%) treated aniseeds. In conclusion, the results demonstrated the potential and positive efficacies of 5-ALA to improve the pharmaceutical properties and oil composition of aniseeds. [ABSTRACT FROM AUTHOR]

Objectives: The uvuloglossopharyngeal dimensions (UGPDs) are assumed to be affected by thalassemia major (TM). Because thalassemia intermedia (TI) is a milder form without need for blood transfusions, this study aimed to evaluate whether the UGPDs in thalassemic patients are equally affected by the two forms. Methods: The study sample comprised 52 lateral cephalograms from thalassemic patients (31 TM; 21 TI) aged 12.98 ± 1.66 years. The control group comprised 25 lateral cephalograms from non-thalassemic subjects aged 13.64 ± 1.55 years with ANB > 3°. Linear measurements including tongue length (TGL), tongue height (TGH), soft palate length, uvula thickness (UT), superior airway space, middle airway space, inferior airway space, and mandibular plane to hyoid (MP-H) were recorded using AutoCAD 2007 software. Results: Mean TGL, TGH, and MP-H in the thalassemic patient group were significantly smaller than those in the control group (all P < 0.05). Conversely, the mean UT was significantly greater than that in the control group ( P < 0.001). The mean TGH, TGL, and MP-H in the control group were significantly greater than those in the TM and TI groups and the mean UT in the control group was significantly smaller than those in the TM and TI groups (all P < 0.05). Conclusions: There were significant differences in some airway components (TGL, TGH, MP-H, UT) between the thalassemic patient group and the control group based on lateral cephalograms as a reliable tool. However, there were no significant differences in these measurements between TM and TI patients. [ABSTRACT FROM AUTHOR]

Background and Purpose: Sand and Dust storms (SDS) are meteorological hazards that are increasing due to climate change. Mitigation and adaptation are two main strategies that help to deal with this global concern. In the recent decades, Iran has been prone to SDS. Therefore, this study was conducted in 2018 in order to explore the SDS adaptation experiences and strategies in the Iranian community.Using content analysis approach and purposive sampling, three groups (including 14 experts, 8 authorities, and 23 individuals) were selected. Data were collected through semi-structured interviews. Data analysis was performed using Graneheim and Lundman’s method. Finally, Gaba and Lincoln’s scientific criteria were used for data validity.Two major categories emerged from the analysis. The first category was related to the adaptation experiences and included two subcategories: “citizens’ experiences” and “experts’/ authorities’ experiences”. The second was related to SDS adaptation strategies and included five subcategories: “educational development”, “public participation”, “inter-sectorial coordination”, “institutional development”, and “environment preservation”.Identifying the experiences and strategies that are implemented by a community to adapt to SDS is the core stone for developing a comprehensive local and national adaptation plan. This study suggests strategies and action plans for SDS adaptation that can be used in policy making.Methods: Sand and Dust storms (SDS) are meteorological hazards that are increasing due to climate change.
