Harokopio University is a public research university in Athens, Greece. Founded in 1990 as the successor of the Harokopios Higher School of Home Economics that was established in 1929, the university has ever since expanded to further scientific areas. Harokopio awards bachelor's, master's, as well as Ph.D. degrees. Wikipedia.

To record the prevalence of overweight and obesity in urban primary-school children in relation to several socio-economic and demographic factors. Cross-sectional. A representative sample of 729 schoolchildren (379 male and 350 female), aged 9-13 years, stratified by parental educational level, was examined in the urban region of Athens. Weight and height were measured using standard procedures. The International Obesity Task Force thresholds were used for the definition of overweight and obesity. Several socio-economic and demographic data and the child's 'popularity' score were also recorded with specifically designed standardized questionnaires. The prevalence of overweight and obesity was 29·6 % and 11·1 %, respectively. Annual family income of € 12,000-20,000 (OR = 1·58), residence ownership (OR = 1·63) and the grandmother as the child's primary caregiver (OR = 1·38) were significantly associated with higher odds of childhood overweight and obesity. Non-Greek parental nationality (OR = 0·72) and higher 'popularity' scores of children (OR = 0·42) were significantly associated with lower odds of overweight and obesity. The grandmother as the child's primary caregiver and an annual family income of € 12,000-20,000 remained significantly associated with childhood overweight and obesity after adding all significant correlates of childhood overweight and obesity observed at the bivariate level in a multivariate regression model (OR = 1·51 and 1·61, respectively). Among family income, residence ownership, child's primary caregiver, parental nationality and popularity scores that were identified as significant correlates of childhood overweight and obesity at the bivariate level, lower family income and grandmother as the child's primary caregiver were the only factors that remained significantly associated with childhood overweight and obesity at a multivariate level.

Purpose of review: Fat accumulation in the liver is strongly associated with metabolic dysfunction. Regular exercise improves many cardiometabolic risks factors; however, its effect on intrahepatic triglyceride (IHTG) content remains elusive. This article summarizes available data regarding the effects of exercise on IHTG. Recent findings: Several but not all observational studies report negative associations of habitual physical activity and cardiorespiratory fitness with IHTG and the prevalence of fatty liver. Aerobic exercise training in combination with hypocaloric diet reduces IHTG by a considerable amount (20-60%), even when weight loss is mild (<5%); hence weight loss per se may not be a critical factor. Longitudinal studies involving exercise training without dietary restriction and no weight loss demonstrate that increased cardiorespiratory fitness and reduced intra-abdominal adiposity are not invariably associated with liver fat depletion, whereas relatively large exercise-induced reductions in IHTG content (20-40%) can occur even in the absence of changes in body weight, body composition, or visceral adipose tissue. Although the majority of studies have examined aerobic training, resistance exercise has also been shown to be inversely associated with the prevalence of fatty liver in humans and effectively reduces IHTG content in animals. Summary: Exercise does hold promise as an effective treatment for hepatic steatosis; this field of research is still in its infancy, and there is much more to be learned. © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins.

The paper discusses certain issues of regional development theory in combination with long-forgotten conditions of uneven geographical development in the context of the current financial and debt crisis in the eurozone. The dominant explanations of the crisis are mainly macroeconomic and financial but this paper argues for its geographical components/foundations. After a short descriptive comment about the current debt crisis in the eurozone and particularly in Southern Europe as part of the wider global crisis of over-accumulation, an alternative interpretation is provided based on uneven geographical/regional development among Euro-regions, especially since the introduction of the euro. The paper also discusses the shift towards what we may call the neoliberal urban and regional development discourse, which is responsible for a de-politicized shift in regional theory and hence downplaying or simply overlooking questions of socio-spatial justice. The discussion about justice and solidarity goes beyond the controversial rescue plan introduced by the European Union and the International Monetary Fund, which was supposedly designed to help one of the so-called - in a typical colonial way - PIIGS (Portugal, Italy, Ireland, Greece and Spain), namely Greece. © The Author(s) 2011.

Regional Studies. This paper explores the prima facie puzzling issue of why so much contemporary theory in economic geography and regional planning - specifically New Economic Geography (NEG) and New Regionalism (NR) - has so little to say about the causes of the current post-2007 crisis and its geography globally and in Europe. It is argued here that this reflects its obsession with the regional 'success stories' of the 1970s and 1980s, its failure to appreciate the onset of crisis and the reasons for it in these regions in the 1990s, and its failure to appreciate the nature of capitalism as a crisis prone social system of combined and uneven development. Thus, the current economic crisis pushed dominant regional development theories into a homologous deep theoretical crisis. It is concluded that the time is ripe for a paradigm shift in theory and that this should involve a reconsideration of earlier theoretical approaches that fell out of fashion for a variety of intellectual and political reasons and of current radical social movements. © 2013 © 2013 Regional Studies Association.

The aim of the study was to investigate the effects of sesame oil on endothelial function and to detect the underlying mechanisms, both in the postprandial state and after long-term consumption. We enrolled 30 hypertensive men in a two-phase study. In the first phase, 26 volunteers consumed 35 g of either sesame oil or control oil. Endothelial function, inflammatory activation and nitric oxide syntase (NOS) inhibition was assessed after a 12-hour fast and 2 hours after consumption of an oil-containing standardized meal. In the second phase, 30 volunteers consumed 35 g of sesame oil or control oil daily for 2 months and the above-mentioned parameters were assessed at baseline, 15, 30 and 60 days. Methods: Endothelial function was estimated by endothelium-dependent FMD (flow-mediated dilatation) of the brachial artery. Flow-mediated dilatation (FMD) improved significantly both after acute (p = 0.001) and long-term sesame oil consumption (p = 0.015, p = 0.005 and p = 0.011 for 15, 30 and 60 days respectively). Intracellular adhesion molecule (ICAM) levels decreased significantly after only 60 days of daily sesame oil intake (p = 0.014). By contrast, no changes were observed in the control group in either phase of the study. This is the first study to show that sesame oil consumption exerts a beneficial effect on endothelial function and this effect is sustained with long-term daily use. Source
