    The aim of this work was to determine the fatty acids (FA), tocopherols, phenols, and antioxidant capacity (AC) of five virgin olive oils (VOO) obtained from the olive cultivar 'Roghiani', from different regions of northern Libya during the crop year 2015. The parameters determined for the oils were investigated for the first time. Seven principal FAs were detected in the VOO samples. Oleic, palmitic, and linoleic acids were the dominant ones. The highest percentage of palmitic acid was found in Tripoli VOO (P lt = 0.05). Oleic acid was dominant in all the VOO samples. Gharyan VOO possessed the highest value of oleic acid, O/L ratio, monounsaturated fatty acids (MUFA), total phenols content (TPC), total tocopherol and tocotrienol contents (TTC), and AC(DPPH)% (P lt = 0.05). A strong positive relationship between TPC and (AC) as (1/EC50DPPH) was observed, (r) was +0.831. On the other hand, (1/EC50DPPH) showed a positive correlation with TTC, (r) was +0.768

    We report photometric follow-up observations of thirteen exoplanets (HATS-1 b, HATS-2 b, HATS-3 b, HAT-P-18 b, HAT-P-27 b, HAT-P-30 b, HAT-P-55 b, KELT-4A b, WASP-25 b, WASP-42 b, WASP-57 b, WASP-61 b and WASP-123 b), as part of the Original Research By Young Twinkle Students (ORBYTS) programme. All these planets are potentially viable targets for atmospheric characterisation and our data, which were taken using the LCOGT network of ground-based telescopes, will be combined with observations from other users of ExoClock to ensure that the transit times of these planets continue to be well-known, far into the future

    European Society of Cardiology: Cardiovascular Disease Statistics 2019

    Aims The 2019 report from the European Society of Cardiology (ESC) Atlas provides a contemporary analysis of cardiovascular disease (CVD) statistics across 56 member countries, with particular emphasis on international inequalities in disease burden and healthcare delivery together with estimates of progress towards meeting 2025 World Health Organization (WHO) non-communicable disease targets. Methods and results In this report, contemporary CVD statistics are presented for member countries of the ESC. The statistics are drawn from the ESC Atlas which is a repository of CVD data from a variety of sources including the WHO, the Institute for Health Metrics and Evaluation, and the World Bank. The Atlas also includes novel ESC sponsored data on human and capital infrastructure and cardiovascular healthcare delivery obtained by annual survey of the national societies of ESC member countries. Across ESC member countries, the prevalence of obesity (body mass index ≥30 kg/m2) and diabetes has increased two- to three-fold during the last 30 years making the WHO 2025 target to halt rises in these risk factors unlikely to be achieved. More encouraging have been variable declines in hypertension, smoking, and alcohol consumption but on current trends only the reduction in smoking from 28% to 21% during the last 20 years appears sufficient for the WHO target to be achieved. The median age-standardized prevalence of major risk factors was higher in middle-income compared with high-income ESC member countries for hypertension {23.8% [interquartile range (IQR) 22.5–23.1%] vs. 15.7% (IQR 14.5–21.1%)}, diabetes [7.7% (IQR 7.1–10.1%) vs. 5.6% (IQR 4.8–7.0%)], and among males smoking [43.8% (IQR 37.4–48.0%) vs. 26.0% (IQR 20.9–31.7%)] although among females smoking was less common in middle-income countries [8.7% (IQR 3.0–10.8) vs. 16.7% (IQR 13.9–19.7%)]. There were associated inequalities in disease burden with disability-adjusted life years per 100 000 people due to CVD over three times as high in middle-income [7160 (IQR 5655–8115)] compared with high-income [2235 (IQR 1896–3602)] countries. Cardiovascular disease mortality was also higher in middle-income countries where it accounted for a greater proportion of potential years of life lost compared with high-income countries in both females (43% vs. 28%) and males (39% vs. 28%). Despite the inequalities in disease burden across ESC member countries, survey data from the National Cardiac Societies of the ESC showed that middle-income member countries remain severely under-resourced compared with high-income countries in terms of cardiological person-power and technological infrastructure. Under-resourcing in middle-income countries is associated with a severe procedural deficit compared with high-income countries in terms of coronary intervention, device implantation and cardiac surgical procedures. Conclusion A seemingly inexorable rise in the prevalence of obesity and diabetes currently provides the greatest challenge to achieving further reductions in CVD burden across ESC member countries. Additional challenges are provided by inequalities in disease burden that now require intensification of policy initiatives in order to reduce population risk and prioritize cardiovascular healthcare delivery, particularly in the middle-income countries of the ESC where need is greatest

    The objective of this study was to investigate the nutritional value of seven samples of cold pressed a pumpkin oil of different origins and influence of seed origin on the content of the most important bioactive components. Four samples of a pumpkin oil is obtained by cold pressing of the seeds of domestic and Austrian varieties, and three samples of cold pressed oils were obtained from the seeds of unknown origin, taken by free choice in the market. As indicators of the nutritional values are determined by the composition and content of fatty acids, tocopherols and sterols. In the composition of the fatty acid were oleic dominant (34,2±0,09 - 43,9±0,04%) and linolenic fatty acid (30,8±0,09 - 46,9±0,015%). This study confirmed that the oil pumpkin dominant ?+?-tocopherol, whose contents ranged from 34,65±0,03 to 44,59±0,69 mg/100g. We determine the composition and content of ?7 phytosterols, especially for specific oil pumpkins. Was detected five ?7 sterol: Spinasterol, ?7,22,25-stigmastatrienol, ?7,25-stigmastadienol, ?7-stigmasterol and ?7-avenasterol. Dominant its content was ?7,22-stigmastadienol or Spinasterol with 39,98 to 50,31% of the total content of sterols

    Five cultivars (Sampion, Jupiter, Sejnovo, Elit, and Geisenheim 139) of walnuts (Juglans regia L.) were collected during the 2008 harvest, from Cacak, Central Serbia. Two techniques of oil extraction were implemented - cold pressing and organic solvent extraction. The influence of the implemented methods on the fatty acid composition, tocopherol content as well as oxidative stability was examined. Predominant fatty acids were palmitic, oleic, linoleic, and linolenic acids. The oleic acid content of the oils ranged from 15.9-23.7% of the total fatty acids, while the linoleic acid content ranged from 57.2-65.1% and that of linolenic acid from 9.1-13.6%. The process of oil extraction had no significant effect on the content and composition of fatty acids in the oil. The total content of tocopherols ranged from 28.40 mg/100 g to 42.40 mg/100 g of the extracted oil. The most common tocopherol in all samples was γ-tocopherol. The oil extracted using the Soxhlet method contained higher amounts of total tocopherols while the stability of the oil samples, expresed as induction period, ranged from 5.0 h to 7.1 hours. Reduced stability of the oil samples as measured by the Rancimat method was negatively correlated with the level of linolenic acid and total content of tocopherols

    Antioxidant (AO) activity of cold pressed pumpkin (Cucurbita pepo L.) seed oil, produced from three naked and one hulled variety, was assessed using a DC polarographic assay based on a hydrogen peroxide scavenge (HPS). Results are expressed as the decrease of the anodic oxidation current of hydrogen peroxide obtained upon addition of methanolic extract of the investigated oils. Strict correlations of HPS and (1) radical scavenging capacity against the stable free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH) (0.99), (2) the induction period estimated by a Rancimat test (0.99) and (3) total phenolic content estimated by Folin-Ciocalteu (FC) assay (0.99) were obtained. In addition, a significant correlation of HPS and the content of delta-tocopherol (0.87), squalene (0.67) and color CIE a* (-0.89) was found. Based on the results reported, the polarographic assay was found to be suitable for determination of AO activity as an indicator of the quality and oxidative stability of oil

    © 2020 Inst. Sci. inf., Univ. Defence in Belgrade. All rights reserved. Background/Aim: Vitamin D insufficiency/deficiency is often present in patients with type-2 diabetes mellitus (DM) and could present a risk factor for rapid progression of diabetic nephropathy and for higher incidence of cardiovascular events. The aim of this study was to examine the influence of vitamin D supplementation on proteinuria, cholesterol, triglycerides, C-reactive protein (CRP) and hemoglobin A1c in patients with type-2 DM and vitamin D insufficiency/deficiency. Methods: This prospective, cohort study included 90 patients with type-2 DM and vitamin D insufficiency/deficiency divided into 3 equal groups: with normal proteinura, with microproteinuria and with macroproteinuria. Therapy included six months of supplementation with cholecalciferol drops: first two months with 20,000 IU twice weekly, than if level of vitamin D was below normal the same dose was given next four months. If the level of vitamin D was normal 5,000 IU was given twice weekly. At the begining and at the end of the study the levels of urea, creatinine, fasting blood glucose, calcium, phosphorus, cholesterol, triglycerides, CRP, hemoglobin A1c, intact parathyroid hormone, 24-hour urine protein and creatinine clearance were determined. Levels of calcium, phosphorus and vitamin D were also checked 2 months after beginning of therapy due to possible correction of cholecalciferol dose. Results: The lowest level of vitamin D before therapy was found in patients with macroproteinuria, while at the end of the study the significantly higher level of vitamin D was found in all three groups. After 6 months of therapy a significant decrease of 24-hour urine protein, cholesterol, triglycerides, hemoglobin A1c in all three groups, and CRP in patients with normal proteinuria and microproteinuria were found. Significantly negative correlation between vitamin D and 24-hour urine protein, cholesterol and CRP was found in patients with macroproteinuria. Also, significantly negative correlation was found between vitamin D and hemoglobin A1c, in patients with normal proteinuria, vitamin D and CRP in patients with microproteinuria. Conclusion: A preventive use of high-dose cholecalciferol supplementation in patients with type-2 DM (with or without proteinuria) decreases cholesterol, triglycerides, proteinuria, CRP and hemoglobin A1c

    Three Approaches to Urban Conflicts over Peace(s)

    No full text
    This chapter first argues that urban conflicts over peace(s) in the postwar city should be studied through the acts, governing, and spaces underpinning them. It then theorises negotiating agency, governmentality, and relational space as concepts apt for analysing these dimensions. Negotiating agency sees acts are the result of open-ended and constantly on-going negotiations between the subject and the world in which it exists. The key to understanding acts therefore lies neither in the subject nor the world, but in the negotiation between the two underpinning the act itself. Governmentality understands governing as about structuring the field of possible acts for collectives—effectively meaning that anything making collectives choose A instead of B is considered governing. Relational space in turn builds on the notion that space is neither given nor passive to but rather both produced by and productive of society. The chapter ends with some notes on research design
