Ensuring “stability of the real estate legal situation” in the Iranian land recording system

The topic of recording real estate transactions and the documentation of the rights of all parties is a controversial topic under the Iranian recording system. One of the functions of the recording system is “assuring security” regarding the stability of real estate property transactions, which can affect the rights of third parties as well. “Security” in transactions requires establishing priority for recorded transactions and observing rights concerning unrecorded ones. This means that the developed form of the recording system must move from “static security” to “dynamic security” in order to protect public interests instead of private ones. In reviewing the Iranian legal system, the bases of “Dynamic Security” can identified in various laws related to the recording of real estate transactions that legally recognize formal deeds and recorded rights. However, since these bases have not been theorized yet, there is not enough sanction to guarantee the enforcement of this theory. In addition, judicial procedure has issued a lot of sentences implying the acceptance of “Static Security”, so that private interests are considered much more important than public interests. The lack of any formal and legal “Dynamic Security” theory has even led legislators to adopt rules against this theory by granting the authority to judges to give effect to informal documents as well. All this has resulted in a lack of security and stability in the recording system, which has led to a lack of trust by all parties in trusting the information and the content of a registration book, because any kind of transaction can be nullified by a judicial decision. In applying a qualitative method and content analysis, it can be concluded that “Dynamic Security” can provide very useful tools for guaranteeing the security and stability of real estate transactions. Consequently, it is essential to theorize this security and consider it in the law and practical procedures relating to it

Feasibility study of rainbow trout (Oncorhynchus mykiss ) culture in brackish water in earthen fish pond in North Khorasan province

The use correct of non-agricultural land due to saline and waternon fresh for rearing of aquatic animals, especially fish, in good seasons, can generate for employment and provide fertile ground . This study aimed to assess the ability of Rainbow Trout reared in earthen ponds potential using brackish water stub area south of North Khorasan province in cold seasons (autumn and winter) have been conducted. Farming operations in three earthen ponds, each with an area of 3,000 square meters and two water wells within 160 days of the initial electric Bahdayt 8400 and 18100 µs was conducted. Average initial weight of juveniles when introduced into soil ponds 32.0±1.0 and 22.7±1/7 grams and density drop in the of ponds 5 and 7 number per cubic meters . Feeding on pond done recipes nutrition standards Related to fish size and water temperature was during the period culture . To help improve the water quality during the breeding ponds of cyclic change in volume of pond water (20-15%) and two aeration SPLASH with errive fresh water to form rain fall in each pond was used. The results obtained during the period of measurement water physico-chemical parameters (temperature, electrical conductivity, dissolved oxygen, nutrients, total dissolved substances, acidity) shows changes in the mean amplitude of these factors has been tolerated for raising trout The results showed that children reared trout have been introduced since the introduction of nteroperability with brackish water in the pond also grown to over 14 thousand have salt and water changes physical and chemical factors have endured. The results showed that fish farming in addition to works by adapting the environment had to foster the growth of the pond water . So in 5 months, with a mean survival of 87 percent hindrance develop marketable size with an average weight of 340±12-390±13and 470 ±17grams and have a total production of more than 20 tonnes. All of it has been confirmed, the study area (SFRAIEN)is very suitable for the breeding Rainbow trout of pond during the fall and winter seasons

Mapping 123 million neonatal, infant and child deaths between 2000 and 2017

Since 2000, many countries have achieved considerable success in improving child survival, but localized progress remains unclear. To inform efforts towards United Nations Sustainable Development Goal 3.2—to end preventable child deaths by 2030—we need consistently estimated data at the subnational level regarding child mortality rates and trends. Here we quantified, for the period 2000–2017, the subnational variation in mortality rates and number of deaths of neonates, infants and children under 5 years of age within 99 low- and middle-income countries using a geostatistical survival model. We estimated that 32% of children under 5 in these countries lived in districts that had attained rates of 25 or fewer child deaths per 1,000 live births by 2017, and that 58% of child deaths between 2000 and 2017 in these countries could have been averted in the absence of geographical inequality. This study enables the identification of high-mortality clusters, patterns of progress and geographical inequalities to inform appropriate investments and implementations that will help to improve the health of all populations

Mapping disparities in education across low- and middle-income countries

Analyses of the proportions of individuals who have completed key levels of schooling across all low- and middle-income countries from 2000 to 2017 reveal inequalities across countries as well as within populations. Educational attainment is an important social determinant of maternal, newborn, and child health(1-3). As a tool for promoting gender equity, it has gained increasing traction in popular media, international aid strategies, and global agenda-setting(4-6). The global health agenda is increasingly focused on evidence of precision public health, which illustrates the subnational distribution of disease and illness(7,8); however, an agenda focused on future equity must integrate comparable evidence on the distribution of social determinants of health(9-11). Here we expand on the available precision SDG evidence by estimating the subnational distribution of educational attainment, including the proportions of individuals who have completed key levels of schooling, across all low- and middle-income countries from 2000 to 2017. Previous analyses have focused on geographical disparities in average attainment across Africa or for specific countries, but-to our knowledge-no analysis has examined the subnational proportions of individuals who completed specific levels of education across all low- and middle-income countries(12-14). By geolocating subnational data for more than 184 million person-years across 528 data sources, we precisely identify inequalities across geography as well as within populations.Peer reviewe

Global injury morbidity and mortality from 1990 to 2017 : results from the Global Burden of Disease Study 2017

Correction:Background Past research in population health trends has shown that injuries form a substantial burden of population health loss. Regular updates to injury burden assessments are critical. We report Global Burden of Disease (GBD) 2017 Study estimates on morbidity and mortality for all injuries. Methods We reviewed results for injuries from the GBD 2017 study. GBD 2017 measured injury-specific mortality and years of life lost (YLLs) using the Cause of Death Ensemble model. To measure non-fatal injuries, GBD 2017 modelled injury-specific incidence and converted this to prevalence and years lived with disability (YLDs). YLLs and YLDs were summed to calculate disability-adjusted life years (DALYs). Findings In 1990, there were 4 260 493 (4 085 700 to 4 396 138) injury deaths, which increased to 4 484 722 (4 332 010 to 4 585 554) deaths in 2017, while age-standardised mortality decreased from 1079 (1073 to 1086) to 738 (730 to 745) per 100 000. In 1990, there were 354 064 302 (95% uncertainty interval: 338 174 876 to 371 610 802) new cases of injury globally, which increased to 520 710 288 (493 430 247 to 547 988 635) new cases in 2017. During this time, age-standardised incidence decreased non-significantly from 6824 (6534 to 7147) to 6763 (6412 to 7118) per 100 000. Between 1990 and 2017, age-standardised DALYs decreased from 4947 (4655 to 5233) per 100 000 to 3267 (3058 to 3505). Interpretation Injuries are an important cause of health loss globally, though mortality has declined between 1990 and 2017. Future research in injury burden should focus on prevention in high-burden populations, improving data collection and ensuring access to medical care.Peer reviewe

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 age-sex-specific fertility, mortality, healthy life expectancy (HALE), and population estimates in 204 countries and territories, 1950-2019 : a comprehensive demographic analysis for the Global Burden of Disease Study 2019

Background: Accurate and up-to-date assessment of demographic metrics is crucial for understanding a wide range of social, economic, and public health issues that affect populations worldwide. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 produced updated and comprehensive demographic assessments of the key indicators of fertility, mortality, migration, and population for 204 countries and territories and selected subnational locations from 1950 to 2019. Methods: 8078 country-years of vital registration and sample registration data, 938 surveys, 349 censuses, and 238 other sources were identified and used to estimate age-specific fertility. Spatiotemporal Gaussian process regression (ST-GPR) was used to generate age-specific fertility rates for 5-year age groups between ages 15 and 49 years. With extensions to age groups 10–14 and 50–54 years, the total fertility rate (TFR) was then aggregated using the estimated age-specific fertility between ages 10 and 54 years. 7417 sources were used for under-5 mortality estimation and 7355 for adult mortality. ST-GPR was used to synthesise data sources after correction for known biases. Adult mortality was measured as the probability of death between ages 15 and 60 years based on vital registration, sample registration, and sibling histories, and was also estimated using ST-GPR. HIV-free life tables were then estimated using estimates of under-5 and adult mortality rates using a relational model life table system created for GBD, which closely tracks observed age-specific mortality rates from complete vital registration when available. Independent estimates of HIV-specific mortality generated by an epidemiological analysis of HIV prevalence surveys and antenatal clinic serosurveillance and other sources were incorporated into the estimates in countries with large epidemics. Annual and single-year age estimates of net migration and population for each country and territory were generated using a Bayesian hierarchical cohort component model that analysed estimated age-specific fertility and mortality rates along with 1250 censuses and 747 population registry years. We classified location-years into seven categories on the basis of the natural rate of increase in population (calculated by subtracting the crude death rate from the crude birth rate) and the net migration rate. We computed healthy life expectancy (HALE) using years lived with disability (YLDs) per capita, life tables, and standard demographic methods. Uncertainty was propagated throughout the demographic estimation process, including fertility, mortality, and population, with 1000 draw-level estimates produced for each metric. Findings: The global TFR decreased from 2·72 (95% uncertainty interval [UI] 2·66–2·79) in 2000 to 2·31 (2·17–2·46) in 2019. Global annual livebirths increased from 134·5 million (131·5–137·8) in 2000 to a peak of 139·6 million (133·0–146·9) in 2016. Global livebirths then declined to 135·3 million (127·2–144·1) in 2019. Of the 204 countries and territories included in this study, in 2019, 102 had a TFR lower than 2·1, which is considered a good approximation of replacement-level fertility. All countries in sub-Saharan Africa had TFRs above replacement level in 2019 and accounted for 27·1% (95% UI 26·4–27·8) of global livebirths. Global life expectancy at birth increased from 67·2 years (95% UI 66·8–67·6) in 2000 to 73·5 years (72·8–74·3) in 2019. The total number of deaths increased from 50·7 million (49·5–51·9) in 2000 to 56·5 million (53·7–59·2) in 2019. Under-5 deaths declined from 9·6 million (9·1–10·3) in 2000 to 5·0 million (4·3–6·0) in 2019. Global population increased by 25·7%, from 6·2 billion (6·0–6·3) in 2000 to 7·7 billion (7·5–8·0) in 2019. In 2019, 34 countries had negative natural rates of increase; in 17 of these, the population declined because immigration was not sufficient to counteract the negative rate of decline. Globally, HALE increased from 58·6 years (56·1–60·8) in 2000 to 63·5 years (60·8–66·1) in 2019. HALE increased in 202 of 204 countries and territories between 2000 and 2019

A study of cytochrome P-448, a component of the monooxygenase system from Saccharomyces ceresvisiae: Purification and characterization.

The effect of glucose concentration in growth medium on biosynthesis of cytochrome P-450/P-448 under aerobic and anaerobic conditions was examined. High glucose concentration was required in both cases. The cytochrome P-450 enzyme from yeast Saccharomyces cerevisiae showed a Soret peak in the reduced CO-difference spectrum at 448nm, was purified to homogenity and had a molecular weight of 55,500. Cytochromes c(P-450) reductase, b[5], b[5] reductase were also purified from the same microsomal preparation. Amino acid analysis of yeast cytochrome P-448 revealed the presence of 407 residues per molecule. The sum of molecular weight of the polypeptides and other components was in good agreement with the molecular weight value obtained from SDS-polyacrylamide gel electrophoresis. A reconstituted system of purified yeast cytochrome P-448, NADPH:cytochrome c(P-450) reductase and phospholipid showed benzo(a)pyrene hydroxylase activity. The spin state of substrate-free and benzo(a)pyrene-bound purified yeast cytochrome P-448 were 94% and 82% low spin at 22°C respectively. Equilibrium gel filtration analysis of the number of benzo(a)pyrene binding sites per mole of enzyme monomer showed a value of 1 for purified yeast cytochrome P-448 and 6 for this enzyme in microsomal form. In addition to benzo(a)pyrene, lanosterol, ethylmorphine, dimethylnitrosamine and sodium phenobarbitone showed Type I binding spectra with yeast cytochrome P-448. A more specific and efficient form of benzo(a)pyrene hydroxylase was induced by the addition of benzo(a)pyrene to the yeast growth medium at zero time. Based on the effect of modification of various amino acids on parameters of yeast cytochrome P-448, participation of -SH group(s) and tyrosyl residue(s) in the active site of this enzyme is suggested. Various supports were evaluated for immobilization of yeast cytochrome P-448. Calcium alginate was found to be especially useful. Cytochrome P-448 from Saccharomyces cerevisiae is identified as a distinct enzyme of the cytochrome P-450 family. This enzyme, however, has many properties in common with cytochrome P-448 from mammalian sources
