A Study of Relationship between Library Anxiety and Emotional Intelligence among Students of University of Tabriz and Azarbaijan Shahid Madani University

The main objective of the present research was the possibility of predicting library anxiety (LA) concerning students’ emotional intelligence (EI). This study's objective, practical research, data gathering, and research method are descriptive correlational studies. Graduate students of Azarbaijan Shahid Madani University and Tabriz University make up the statistical population of this research. Based on Morgan’s formulae for sample size determination, 298 and 350 students were selected as the study's sample size. Then, the random sampling method was used to prepare the questionnaires, which were distributed and collected. The required information in preparing the questionnaires was taken from Siberia Schering's Emotional Intelligence and the “library anxiety questionnaire.” For examining the research hypotheses, Pearson Correlation Test and stepwise regression were used. Based on the present study's findings, the average emotional intelligence scores of students of Azarbaijan Shahid Madani University and Tabriz University were above-average, i.e. 3.003 and 3.169, respectively. The correlation of the coefficients of emotional intelligence and library anxiety turned out to be -0.38. Also, the multiple regression analysis results showed that 17% of the changes in library anxiety can be predicted or revealed based on students’ emotional intelligence, and that 83% percent of them depend on other reasons. The findings of this research can raise the awareness about the status of students’ emotional intelligence and library anxiety among officials of Azarbaijan Shahid Madani University and Tabriz University and help with future decision-making and planning. https://dorl.net/dor/20.1001.1.20088302.2022.20.1.1.

Preliminarily report on molecular diversity of Sargassum species in Oman Sea by using ISSR and RAPD markers

Sargassum (Sargassaceae, Fucales) is a common macroalgal genus occurring throughout the world, except in the polar regions. Sargassum species are one of economically important brown algae in south of Iran. In this study, molecular variations were assessed in three Sargassum species; Sargassum tenerrimum J. Agardh, Sargassumglaucescens J. Agardh and Sargassum ilicifolium C.Agardh, widely distributed species in the southwest of Iran (Oman Sea). RAPD and ISSR markers were used to assess genetic variation within populations of each 3 species. Four of 30 RAPD primers as well as six combination of RAPD primers which have been used which all produced reproducible bands with high polymorphism (>96%). All populations in 3 species showed unique alleles which made unique profiles for each population. Twelve ISSR markers including single and combined primers showed high polymorphism (>94%). Nei’s genetic diversity, Shannon index showed high values between populations while no variations were observed within populations (Hpop =0, 1-Hpop/Hsp =1) in both molecular markers studied. AMOVA test also confirmed lack of variation within them. Different clustering like UPGMA and Neighbor Joining separated populations of each species studied based on RAPD and ISSR data. This is the first study on evaluation of inter-population variation in some of Sargassum species in Iran

The effects of Dendrobium species on the metabolic syndrome: A review

Metabolic syndrome (MetS) is known as a global health challenge with different types of health conditions such as hypertension, hyperglycemia, the increasing prevalence of obesity, and hyperlipidemia. Despite much recent scientific progress, the use of traditional herbal medicines with fewer side effects is increasing worldwide. Dendrobium, the second-largest orchid genus, has been used as a natural source of drugs for the treatment of MetS. The beneficial effects of Dendrobium, including anti-hypertension, anti-hyperglycemia, anti-obesity, and anti-hyperlipidemic against MetS have been shown in the scientific evidence. The anti-oxidant and lipid-lowering effects of Dendrobium modulate hyperlipidemia via reducing lipid accumulation and maintaining lipid metabolism. Restoring pancreatic beta cells and regulating the insulin signaling pathway are involved in its antidiabetic properties. The hypotensive effects contribute to increasing nitric oxide (NO) generation and inhibiting extracellular signal-regulated kinase (ERK) signaling. More research projects, especially clinical trials, are needed to investigate the safety, efficacy, and pharmacokinetics of Dendrobium in patients. This review article provides, for the first time, comprehensive information about the efficacy of different species of Dendrobium. The described species can be a source of medicines for the treatment of MetS, which are reported in various evidence

Key Words: Psychological capital, Social capital, Organizational commitment, Effective trainin

Investigating the effect of telmisartan on acrylamide-induced neurotoxicity through in vitro and in vivo methods

Objective(s):  Acrylamide (ACR) is an environmental contaminant and neurotoxin. Telmisartan is an AT1 blocker that has neuroprotective properties basically through its anti-oxidant effect. The effect of telmisartan on ACR-induced neurotoxicity was investigated in this study. Materials and Methods: Male Wistar rats were randomly assigned to eight groups (n=6): 1:Control (normal saline), 2:ACR (50 mg/kg, 11 days, IP), 3:ACR+vitamin E (200 mg/kg, every other day, 11 days), 4-6:ACR+telmisartan (0.6, 1.25, and 2.5 mg/kg, 11 days, IP), 7:ACR+telmisartan (0.6 mg/kg, days 3–11), 8:Telmisartan (2.5 mg/kg, 11 days). The behavioral test and blood pressure were assessed after 11 days. Then, the levels of MDA and GSH in brain tissue were measured. The MTT assay was used to evaluate the effect of telmisartan on ACR-induced cytotoxicity.Results: Exposing PC12 cells to ACR decreased cell viability versus the control group. Pretreating PC12 cells with telmisartan (0.0125, 0.025 µM) enhanced cell viability compared with the ACR group. Compared with control samples, ACR significantly caused motor impairment, elevated MDA, and reduced GSH levels. Locomotor abnormalities were significantly ameliorated by telmisartan (0.6, 1.25 mg/kg, 11 days) and vitamin E versus the ACR group. Receiving telmisartan (0.6, 1.25, and 2.5 mg/kg) and vitamin E along with ACR decreased MDA levels and enhanced GSH content compared with the ACR group.  There was no significant difference in animal blood pressure between the groups.Conclusion: Oxidative stress has a chief role in the neurotoxicity of ACR. Telmisartan (in doses that do not affect blood pressure) ameliorated ACR-induced toxicity by inhibiting oxidative stress

The Effectiveness of the Unified Transdiagnostic Treatment Protocol on the Social Skills of Students with Anxiety Disorders and the Self-Efficacy of their Mothers

The purpose of this study was to evaluate the effectiveness of the unified protocol for transdiagnostic treatment on the social skills of students with anxiety disorders and the self-efficacy of their mothers. This study was a quasi-experimental study with a pretest-posttest design and a control group with one-month and three-month follow-up, which was practical in purpose. The statistical population included all female students aged 8 to 10 years in the academic year 2020-2021 in Tehran and their mothers. Using the available sampling method, 30 anxious schoolgirls were identified and randomly divided into two groups (15 in the control group and 15 in the experimental group). The instrument used in this study was Gresham and Elliott’s Social Skills Questionnaire (SSRS), Spence Children’s Anxiety Questionnaire (SCAS), Teacher Report Form (TRF), and Dumka Patents Self-Efficacy Questionnaire (PSAM), which were completed by the students and mothers before and after the intervention, and after the follow-ups. Then, the experimental group participated in the intervention for 15 sessions of 60 minutes each. Finally, data were analyzed using SPSS software (version 24) and ANOVA with repeated measures. The results showed that the unified protocol for transdiagnostic treatment had a significant effect on improving social skills, reducing children's behavior problems, and increasing mothers’ self-efficacy. It appears that the unified protocol for transdiagnostic treatment can be used as a means to improve students’ social skills and their mothers’ self-efficacy

Due to the influence of this book on hospitals performance,this study aimed to determine and compare the selected statistical indicators of a teaching hospital before and after the implementation of the contents of this book.Materials and Methods: The present cross-sectional descriptive-analytical study was conducted in 2015. Data (statistical indicators) were collected, with the permission and considering the confidentiality of information, through reports review and on-site visiting and analyzed using SPSS (version 17) software.The comparison of selected indicators between paired samples were performed. Correlations were considered significant at α=0.05.Results: Announcement of the value of the notification book resulted in a statistically significant increase in bed occupancy ratio, occupied bed day, average length of stay, and number of hospital death and also a significant decrease of bed turnover interval and rate. Furthermore, a significant increase of inpatients andoutpatients visits and significant decrease of emergency visits and caesarean were also observed.Conclusion: Implementation of the aforementioned book significantly affected some statistical indicators (bed occupancy ratio, occupied bed day, and caesarian), but it has no significant effect on other statistical indicators (inpatients and outpatients visits, emergency visits and number of surgeries). However, extendingthe results of this study to other hospitals requires more extensive studies

Species delimitation and relationship in Crocus L. (Iridaceae)

The genus Crocus L. (Iridaceae) is monophyletic and contains about 100 species throughout the world. Crocus species have horticultural, medicinal and pharmacological importance. Saffron is the dried styles of C. sativus and is one of the world’s most expensive spices by weight. Controversy exits about the taxonomy of the genus and the species relationship. Exploring genetic diversity and inter-specific cross-ability are important tasks for conservation of wild taxa and for breeding of cultivated C. sativus. The present study was performed to study genetic variability and population structure in five Crocus L. species including Crocus almehensis Brickell & Mathew, C. caspius Fischer & Meyer, C. speciosus Marschall von Biberstein, C. haussknechtii Boissier, and C. sativus L. by inter simple sequence repeat (ISSR) molecular markers. We also used published internal transcribed spacer (ITS) sequences to study species relationship and compare the results with ISSR data. The results revealed a high degree of genetic variability both within and among the studied species. Neighbor joining (NJ) tree and network analysis revealed that ISSR markers are useful in Crocus species delimitation. Population fragmentation occurred in C. caspius and C. sativus. Both ISSR and sequenced based analyses separated C. sativus from the other studied species. Close genetic affinity of C. sativus and C. pallisii and inter-specific gene flow was supported by both data sets

Global incidence, prevalence, years lived with disability (YLDs), disability-adjusted life-years (DALYs), and healthy life expectancy (HALE) for 371 diseases and injuries in 204 countries and territories and 811 subnational locations, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

Background: Detailed, comprehensive, and timely reporting on population health by underlying causes of disability and premature death is crucial to understanding and responding to complex patterns of disease and injury burden over time and across age groups, sexes, and locations. The availability of disease burden estimates can promote evidence-based interventions that enable public health researchers, policy makers, and other professionals to implement strategies that can mitigate diseases. It can also facilitate more rigorous monitoring of progress towards national and international health targets, such as the Sustainable Development Goals. For three decades, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) has filled that need. A global network of collaborators contributed to the production of GBD 2021 by providing, reviewing, and analysing all available data. GBD estimates are updated routinely with additional data and refined analytical methods. GBD 2021 presents, for the first time, estimates of health loss due to the COVID-19 pandemic. Methods: The GBD 2021 disease and injury burden analysis estimated years lived with disability (YLDs), years of life lost (YLLs), disability-adjusted life-years (DALYs), and healthy life expectancy (HALE) for 371 diseases and injuries using 100 983 data sources. Data were extracted from vital registration systems, verbal autopsies, censuses, household surveys, disease-specific registries, health service contact data, and other sources. YLDs were calculated by multiplying cause-age-sex-location-year-specific prevalence of sequelae by their respective disability weights, for each disease and injury. YLLs were calculated by multiplying cause-age-sex-location-year-specific deaths by the standard life expectancy at the age that death occurred. DALYs were calculated by summing YLDs and YLLs. HALE estimates were produced using YLDs per capita and age-specific mortality rates by location, age, sex, year, and cause. 95% uncertainty intervals (UIs) were generated for all final estimates as the 2·5th and 97·5th percentiles values of 500 draws. Uncertainty was propagated at each step of the estimation process. Counts and age-standardised rates were calculated globally, for seven super-regions, 21 regions, 204 countries and territories (including 21 countries with subnational locations), and 811 subnational locations, from 1990 to 2021. Here we report data for 2010 to 2021 to highlight trends in disease burden over the past decade and through the first 2 years of the COVID-19 pandemic. Findings: Global DALYs increased from 2·63 billion (95% UI 2·44–2·85) in 2010 to 2·88 billion (2·64–3·15) in 2021 for all causes combined. Much of this increase in the number of DALYs was due to population growth and ageing, as indicated by a decrease in global age-standardised all-cause DALY rates of 14·2% (95% UI 10·7–17·3) between 2010 and 2019. Notably, however, this decrease in rates reversed during the first 2 years of the COVID-19 pandemic, with increases in global age-standardised all-cause DALY rates since 2019 of 4·1% (1·8–6·3) in 2020 and 7·2% (4·7–10·0) in 2021. In 2021, COVID-19 was the leading cause of DALYs globally (212·0 million [198·0–234·5] DALYs), followed by ischaemic heart disease (188·3 million [176·7–198·3]), neonatal disorders (186·3 million [162·3–214·9]), and stroke (160·4 million [148·0–171·7]). However, notable health gains were seen among other leading communicable, maternal, neonatal, and nutritional (CMNN) diseases. Globally between 2010 and 2021, the age-standardised DALY rates for HIV/AIDS decreased by 47·8% (43·3–51·7) and for diarrhoeal diseases decreased by 47·0% (39·9–52·9). Non-communicable diseases contributed 1·73 billion (95% UI 1·54–1·94) DALYs in 2021, with a decrease in age-standardised DALY rates since 2010 of 6·4% (95% UI 3·5–9·5). Between 2010 and 2021, among the 25 leading Level 3 causes, age-standardised DALY rates increased most substantially for anxiety disorders (16·7% [14·0–19·8]), depressive disorders (16·4% [11·9–21·3]), and diabetes (14·0% [10·0–17·4]). Age-standardised DALY rates due to injuries decreased globally by 24·0% (20·7–27·2) between 2010 and 2021, although improvements were not uniform across locations, ages, and sexes. Globally, HALE at birth improved slightly, from 61·3 years (58·6–63·6) in 2010 to 62·2 years (59·4–64·7) in 2021. However, despite this overall increase, HALE decreased by 2·2% (1·6–2·9) between 2019 and 2021. Interpretation: Putting the COVID-19 pandemic in the context of a mutually exclusive and collectively exhaustive list of causes of health loss is crucial to understanding its impact and ensuring that health funding and policy address needs at both local and global levels through cost-effective and evidence-based interventions. A global epidemiological transition remains underway. Our findings suggest that prioritising non-communicable disease prevention and treatment policies, as well as strengthening health systems, continues to be crucially important. The progress on reducing the burden of CMNN diseases must not stall; although global trends are improving, the burden of CMNN diseases remains unacceptably high. Evidence-based interventions will help save the lives of young children and mothers and improve the overall health and economic conditions of societies across the world. Governments and multilateral organisations should prioritise pandemic preparedness planning alongside efforts to reduce the burden of diseases and injuries that will strain resources in the coming decades.
