Study of genetic diversity in different wheat species with various genomes based on morphological characteristics and zinc use efficiency under two zinc-deficient growing conditions

Screening of cash crops to tolerate and grow under low levels of micronutrients is important issue in the plant breeding programs. Thus, the study screened the tolerance of 50 wheat genotypes to zinc (Zn) deficiency in the calcareous soil. The Zn treatment was carried out with application of 5 mg kg-1 (+Zn) and without (-Zn) to the collected soils with initial Zn extractable of 0.5 mg Zn kg-1 soil. The results revealed that the supplementary application significantly increased shoot dry matter, shoot Zn concentration and shoot Zn content compared to the without Zn application (control), but Zn utilization decreased under Zn application. There was considerable genetic variation in Zn efficiency (55 - 118 %), shoot Zn concentration (11.8 - 27.0 and 14.3 - 39.6 mg kg-1 DM under deficient and sufficient Zn, respectively), shoot Zn content (0.56 - 2.02 and 0.90 - 2.83 µg plant-1, under deficient and sufficient Zn, respectively) and Zn utilization efficiency (39 - 87.2 and 31.2 - 71.5 mg DM µg-1 Zn under deficient and sufficient Zn, respectively) within wheat genotypes. Cluster analysis based on Zn efficiency, and shoot dry matter at deficient and adequate Zn conditions classified the genotypes into four clusters. Over the two conditions, the most Zn-efficient and Zn-unefficient genotypes were ‘Ankara-98’ and ‘Altintoprak-98’ and ‘Pg"S’ and ‘Zarin’, respectively. Most durum genotypes had a greater Zn efficiency than modern bread wheat genotypes, therefore these genotypes could be effectively used to breed the new cultivars with high Zn efficiency for calcareous soils

The theme of the world diabetes day 2014; healthy living and diabetes; a nephrology viewpoint.

Annually, on November 14, the world diabetes day (WDD) is celebrated. WDD is a campaign led by the International Diabetes Federation (IDF) and its member associations throughout the world. It was created in 1991 by IDF and World Health Organization (WHO) in response to increasing concerns about the intensifying threat of diabetes worldwide. The WDD 2014 organization marks the first of a three-year (2014-16) emphasis on "healthy living and diabetes". Replacement of whole grain and cereal-based foods with refined grains in diet planning could be an operative and practical strategy in type II diabetic patients. This strategy beyond the development of glycemic control, leads to more benefits for management of other features of diabetes, diminution of diabetes-induced metabolic disorders, and prevents long-term complications especially diabetic kidney disease and cardiovascular disease

Analysis of Yield Stability of Wheat Genotypes Using New Crop Properties Balance Index (CPBI) Method

The study of some important crop characteristics in a population and the consideration of the limitations and possibilities is a general way to define suitable genotypes. Data collected over six years in the cold winter experiment stations of Iran were used to determine to optimal levels of characteristics and the stability parameters of wheat varieties under rainfed conditions. The boundary lines method allowed the determination of optimal levels of days to heading, days to physiological maturity, duration of grain filling, plant height and thousand kernel weight which were 221.2 days, 259.6 days, 33.8 days, 62.5 centimeter and 28.3 grams, respectively. These data were closely equivalent to optimal levels determined using averaging method. The results showed also that the released cultivars in each location had similar maximum crop properties balance index (CPBI). The maximum CPBIs in Maragheh, Kurdestan, Zanjan, Ardabil and Uromeh regions were 155, 270, 150, 182 and 440, respectively. The analysis of adaptation of commonly grown winter wheat varieties showed that �Sardari� is more suitable for regions with cold winters and cool springs along with spring precipitation; �Sabalan� variety is adapted to cold winters and relatively temperate spring with abundant spring precipitation; and �Azar-2� cultivar is suitable for cold falls and temperate springs along with fall-spring precipitation and minimum winter precipitation

The global burden of adolescent and young adult cancer in 2019 : a systematic analysis for the Global Burden of Disease Study 2019

Background In estimating the global burden of cancer, adolescents and young adults with cancer are often overlooked, despite being a distinct subgroup with unique epidemiology, clinical care needs, and societal impact. Comprehensive estimates of the global cancer burden in adolescents and young adults (aged 15-39 years) are lacking. To address this gap, we analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, with a focus on the outcome of disability-adjusted life-years (DALYs), to inform global cancer control measures in adolescents and young adults. Methods Using the GBD 2019 methodology, international mortality data were collected from vital registration systems, verbal autopsies, and population-based cancer registry inputs modelled with mortality-to-incidence ratios (MIRs). Incidence was computed with mortality estimates and corresponding MIRs. Prevalence estimates were calculated using modelled survival and multiplied by disability weights to obtain years lived with disability (YLDs). Years of life lost (YLLs) were calculated as age-specific cancer deaths multiplied by the standard life expectancy at the age of death. The main outcome was DALYs (the sum of YLLs and YLDs). Estimates were presented globally and by Socio-demographic Index (SDI) quintiles (countries ranked and divided into five equal SDI groups), and all estimates were presented with corresponding 95% uncertainty intervals (UIs). For this analysis, we used the age range of 15-39 years to define adolescents and young adults. Findings There were 1.19 million (95% UI 1.11-1.28) incident cancer cases and 396 000 (370 000-425 000) deaths due to cancer among people aged 15-39 years worldwide in 2019. The highest age-standardised incidence rates occurred in high SDI (59.6 [54.5-65.7] per 100 000 person-years) and high-middle SDI countries (53.2 [48.8-57.9] per 100 000 person-years), while the highest age-standardised mortality rates were in low-middle SDI (14.2 [12.9-15.6] per 100 000 person-years) and middle SDI (13.6 [12.6-14.8] per 100 000 person-years) countries. In 2019, adolescent and young adult cancers contributed 23.5 million (21.9-25.2) DALYs to the global burden of disease, of which 2.7% (1.9-3.6) came from YLDs and 97.3% (96.4-98.1) from YLLs. Cancer was the fourth leading cause of death and tenth leading cause of DALYs in adolescents and young adults globally. Interpretation Adolescent and young adult cancers contributed substantially to the overall adolescent and young adult disease burden globally in 2019. These results provide new insights into the distribution and magnitude of the adolescent and young adult cancer burden around the world. With notable differences observed across SDI settings, these estimates can inform global and country-level cancer control efforts. Copyright (C) 2021 The Author(s).

Global burden of 369 diseases and injuries in 204 countries and territories, 1990–2019: a systematic analysis for the Global Burden of Disease Study 2019

Background: In an era of shifting global agendas and expanded emphasis on non-communicable diseases and injuries along with communicable diseases, sound evidence on trends by cause at the national level is essential. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) provides a systematic scientific assessment of published, publicly available, and contributed data on incidence, prevalence, and mortality for a mutually exclusive and collectively exhaustive list of diseases and injuries. Methods: GBD estimates incidence, prevalence, mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) due to 369 diseases and injuries, for two sexes, and for 204 countries and territories. Input data were extracted from censuses, household surveys, civil registration and vital statistics, disease registries, health service use, air pollution monitors, satellite imaging, disease notifications, and other sources. Cause-specific death rates and cause fractions were calculated using the Cause of Death Ensemble model and spatiotemporal Gaussian process regression. Cause-specific deaths were adjusted to match the total all-cause deaths calculated as part of the GBD population, fertility, and mortality estimates. Deaths were multiplied by standard life expectancy at each age to calculate YLLs. A Bayesian meta-regression modelling tool, DisMod-MR 2.1, was used to ensure consistency between incidence, prevalence, remission, excess mortality, and cause-specific mortality for most causes. Prevalence estimates were multiplied by disability weights for mutually exclusive sequelae of diseases and injuries to calculate YLDs. We considered results in the context of the Socio-demographic Index (SDI), a composite indicator of income per capita, years of schooling, and fertility rate in females younger than 25 years. Uncertainty intervals (UIs) were generated for every metric using the 25th and 975th ordered 1000 draw values of the posterior distribution. Findings: Global health has steadily improved over the past 30 years as measured by age-standardised DALY rates. After taking into account population growth and ageing, the absolute number of DALYs has remained stable. Since 2010, the pace of decline in global age-standardised DALY rates has accelerated in age groups younger than 50 years compared with the 1990–2010 time period, with the greatest annualised rate of decline occurring in the 0–9-year age group. Six infectious diseases were among the top ten causes of DALYs in children younger than 10 years in 2019: lower respiratory infections (ranked second), diarrhoeal diseases (third), malaria (fifth), meningitis (sixth), whooping cough (ninth), and sexually transmitted infections (which, in this age group, is fully accounted for by congenital syphilis; ranked tenth). In adolescents aged 10–24 years, three injury causes were among the top causes of DALYs: road injuries (ranked first), self-harm (third), and interpersonal violence (fifth). Five of the causes that were in the top ten for ages 10–24 years were also in the top ten in the 25–49-year age group: road injuries (ranked first), HIV/AIDS (second), low back pain (fourth), headache disorders (fifth), and depressive disorders (sixth). In 2019, ischaemic heart disease and stroke were the top-ranked causes of DALYs in both the 50–74-year and 75-years-and-older age groups. Since 1990, there has been a marked shift towards a greater proportion of burden due to YLDs from non-communicable diseases and injuries. In 2019, there were 11 countries where non-communicable disease and injury YLDs constituted more than half of all disease burden. Decreases in age-standardised DALY rates have accelerated over the past decade in countries at the lower end of the SDI range, while improvements have started to stagnate or even reverse in countries with higher SDI. Interpretation: As disability becomes an increasingly large component of disease burden and a larger component of health expenditure, greater research and developm nt investment is needed to identify new, more effective intervention strategies. With a rapidly ageing global population, the demands on health services to deal with disabling outcomes, which increase with age, will require policy makers to anticipate these changes. The mix of universal and more geographically specific influences on health reinforces the need for regular reporting on population health in detail and by underlying cause to help decision makers to identify success stories of disease control to emulate, as well as opportunities to improve.

Global, regional, and national cancer incidence, mortality, years of life lost, years lived with disability, and disability-Adjusted life-years for 29 cancer groups, 1990 to 2017 : A systematic analysis for the global burden of disease study

Importance: Cancer and other noncommunicable diseases (NCDs) are now widely recognized as a threat to global development. The latest United Nations high-level meeting on NCDs reaffirmed this observation and also highlighted the slow progress in meeting the 2011 Political Declaration on the Prevention and Control of Noncommunicable Diseases and the third Sustainable Development Goal. Lack of situational analyses, priority setting, and budgeting have been identified as major obstacles in achieving these goals. All of these have in common that they require information on the local cancer epidemiology. The Global Burden of Disease (GBD) study is uniquely poised to provide these crucial data. Objective: To describe cancer burden for 29 cancer groups in 195 countries from 1990 through 2017 to provide data needed for cancer control planning. Evidence Review: We used the GBD study estimation methods to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-Adjusted life-years (DALYs). Results are presented at the national level as well as by Socio-demographic Index (SDI), a composite indicator of income, educational attainment, and total fertility rate. We also analyzed the influence of the epidemiological vs the demographic transition on cancer incidence. Findings: In 2017, there were 24.5 million incident cancer cases worldwide (16.8 million without nonmelanoma skin cancer [NMSC]) and 9.6 million cancer deaths. The majority of cancer DALYs came from years of life lost (97%), and only 3% came from years lived with disability. The odds of developing cancer were the lowest in the low SDI quintile (1 in 7) and the highest in the high SDI quintile (1 in 2) for both sexes. In 2017, the most common incident cancers in men were NMSC (4.3 million incident cases); tracheal, bronchus, and lung (TBL) cancer (1.5 million incident cases); and prostate cancer (1.3 million incident cases). The most common causes of cancer deaths and DALYs for men were TBL cancer (1.3 million deaths and 28.4 million DALYs), liver cancer (572000 deaths and 15.2 million DALYs), and stomach cancer (542000 deaths and 12.2 million DALYs). For women in 2017, the most common incident cancers were NMSC (3.3 million incident cases), breast cancer (1.9 million incident cases), and colorectal cancer (819000 incident cases). The leading causes of cancer deaths and DALYs for women were breast cancer (601000 deaths and 17.4 million DALYs), TBL cancer (596000 deaths and 12.6 million DALYs), and colorectal cancer (414000 deaths and 8.3 million DALYs). Conclusions and Relevance: The national epidemiological profiles of cancer burden in the GBD study show large heterogeneities, which are a reflection of different exposures to risk factors, economic settings, lifestyles, and access to care and screening. The GBD study can be used by policy makers and other stakeholders to develop and improve national and local cancer control in order to achieve the global targets and improve equity in cancer care. © 2019 American Medical Association.

Development and analysis of the Soil Water Infiltration Global database

In this paper, we present and analyze a novel global database of soil infiltration measurements, the Soil Water Infiltration Global (SWIG) database. In total, 5023 infiltration curves were collected across all continents in the SWIG database. These data were either provided and quality checked by the scientists who performed the experiments or they were digitized from published articles. Data from 54 different countries were included in the database with major contributions from Iran, China, and the USA. In addition to its extensive geographical coverage, the collected infiltration curves cover research from 1976 to late 2017. Basic information on measurement location and method, soil properties, and land use was gathered along with the infiltration data, making the database valuable for the development of pedotransfer functions (PTFs) for estimating soil hydraulic properties, for the evaluation of infiltration measurement methods, and for developing and validating infiltration models. Soil textural information (clay, silt, and sand content) is available for 3842 out of 5023 infiltration measurements ( ∼ 76%) covering nearly all soil USDA textural classes except for the sandy clay and silt classes. Information on land use is available for 76% of the experimental sites with agricultural land use as the dominant type ( ∼ 40%). We are convinced that the SWIG database will allow for a better parameterization of the infiltration process in land surface models and for testing infiltration models. All collected data and related soil characteristics are provided online in *.xlsx and *.csv formats for reference, and we add a disclaimer that the database is for public domain use only and can be copied freely by referencing it. Supplementary data are available at https://doi.org/10.1594/PANGAEA.885492 (Rahmati et al., 2018). Data quality assessment is strongly advised prior to any use of this database. Finally, we would like to encourage scientists to extend and update the SWIG database by uploading new data to it

Explaining the structural model of predicting sexual anxiety based on self-sexual schemas by examining the mediating role of emotional regulation in men with heart failure.

Background and Aim: sexual relationship anxiety, which refers to the degree of fear of discussing one's sexual relations with another, is an issue that has not been studied in detail as much as others; Therefore, the explanation of the structural model of predicting sexual anxiety was based on self-sexual schemas by examining the mediating role of emotional regulation in men with heart failure. Methods: The current research is a descriptive and correlational quantitative research in terms of fundamental-applicative purpose and in terms of data collection and the nature of the title. The statistical population of this research was men with heart failure who referred to Martyr Dr. Lavasani Hospital in Tehran in 1402. The sampling method in this research was non-random and accessible, and 300 men were selected. In this research, the sexual relationship anxiety questionnaire of Davis (2006), the sexual schema scale of Andersen and Siranoski (1994) and the emotional regulation of Gratz et al. (2006) were used; To analyze the data, Pearson's correlation coefficient test and path analysis were used using spss-22 and amos-18 software. Results: The results showed that the strongest direct effect on sexual relationship anxiety was related to emotional regulation with an effect size of -0.50, followed by self-sexual schema with an effect size of 0.47. The result of the direct effects test showed that these effects are significant at the confidence level of at least 95% (p<0.05). Conclusion: The confirmation of the mediating role of variables shows that in the pathology and treatment of male sexual deviance, paying attention to psychological aspects, especially cognitive and emotional aspects, is as important as paying attention to its physiological aspects. The mediating role of emotional and cognitive variables in the dual control model needs more attentio

Effects of foliar application of zinc sulfate at different phenological stages on yield formation and grain zinc content of bread wheat (cv. Kohdasht)

Zinc (Zn) is an essential mineral nutrient for plant and human growth, and dietary Zn deficiency is a worldwide nutritional problem. Two-year field experiments were conducted during the 2013 and 2014 to evaluate the effects of foliar application of zinc sulfate at the developmental stages on agronomy traits and grain Zn content. The following foliar applications of Zn (0.44 g Zn/lit) at the phenological stages were used: (1) no Zn fertilizer addition (control), (2) stem elongation stage and (3) stemming and grain filling stages. The results showed that foliar Zn application at the stemming and grain filling stages was much more effective than foliar Zn application at the stem elongation stage on grain yield and its components of wheat. Foliar application at stemming and grain filling stages had no significant effect on the harvest index whereas significantly increased plant height. Zn concentration was not changed when plants were sprayed at early stem elongation while significantly increased grain yield and its components. In general, the most effective treatments to ameliorate Zn deficiency were foliar application at stemming and grain filling stages

The Partitioning Trend of Resources and Alpha-Amylase Enzyme Activity with Zinc Priming in Wheat (Triticum aestivum) Seed

The percentage and rate of germination and proper establishment of seedlings are important factors contributing to higher yield per unit area. As an essential element for plant growth and development, Zinc plays a critical role in many metabolic processes, and also has a positive effect on seed germination. The effects of seed priming with concentrations of 0.5, 1 and 2 percent zinc sulfate on the partitioning of reserved materials in seed, the start of autotrophic seedling growth and the activity of alpha-amylase enzyme were investigated in wheat seeds, using a factorial experiment in the Research Farm of the University of Maragheh, Iran in 2014 on the basis of a completely randomized design with four replications. The results showed that zinc priming had a significant effect on all the parameters under investigation. Mean comparisons showed that an increase in zinc concentration- up to one percent- had a positive effect on the parameters investigated and increasing its concentration more than one percent caused a negative effect on the parameters touched upon above. The results of this study showed that the dry seed weight of the control and zinc sulfate (0.5%) treatment reached a stable level on day 21 and 20, respectively. In addition, in the control and 0.5% zinc sulfate, the total dry weight reached its initial weight (seed weight) on day 15 and 13, respectively. In addition, the growth of autotrophic plant began 10-12 days after soaking. The seeds treated with 5.0 and 1 percent zinc sulfate had more leaf area than the other treatments; this could be due to the earlier entrance of the seedlings produced by 5.0 and 1% zinc sulfate treatments into the autotrophic stage, as compared with other treatments. The results of variance analysis of the finishing seeds' reserved materials, initial kernel, root dry weight and shoot dry weight confirmed that 0.5 and 1% zinc sulfate treatments were better than other concentrations. The treatments of 0.5 and 1%&nbsp; of zinc sulfate reached the autotrophic stage sooner than the control and 2% zinc sulfate treatment. Given the results of this study, 5.0 and 1% zinc sulfate treatments were selected for field cultivation. &nbsp
