In an attempt to evaluate the background levels of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), non-ortho, mono-ortho and indicator polychlorinated biphenyls (PCBs) in people living in an urban (Athens) and a rural (Kozani) area of Greece, blood serum and mother milk samples were analyzed. Analytical results are reported(More)
It is widely accepted that a healthy diet is an important factor in preventing chronic diseases, and in improving energy balance and weight management. Studies have shown strong inverse correlations between tomato consumption and the risk of certain types of cancer, cardiovascular diseases and age-related macular degeneration. Because tomato is the(More)
Food intake is the main source of exposure to dioxin-like compounds for humans. The results of a surveillance programme on polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and co-planar polychlorinated biphenyls (co-PCBs) in 77 food samples from the Greek market and producers are presented. The study included the analyses of milk and dairy(More)
Patterns of environmental change in the biosphere include concurrent and sequential combinations of increasing ultraviolet (UV-B) and ozone (O(3)) at increasing carbon dioxide (CO(2)) levels; long-term changes are resulting mainly from stratospheric O(3) depletion, greater tropospheric O(3) photochemical synthesis, and increasing CO(2) emissions. Effects of(More)
This paper sheds light on the importance of the validity of PPP hypothesis for the accessing process of the candidate countries towards EMU. The evidence of nonlinear adjustment in real exchange rates insists the estimation of a nonlinear SETAR model. While linear half-life estimates are biased upward (5 years on average), SETAR half-life estimates imply a(More)
Tomato (Lycopersicon esculentum Mill) ‘Trust’ was grown on rockwool with nutrient solutions containing two levels of calcium (150 and 300 mg·L–1) in factorial combination with three levels of magnesium (20, 50, and 80 mg·L–1) in Winters 1997 and 1998, to investigate the effects of calcium and magnesium on growth, biomass partitioning, and fruit production.(More)
We report here a case study of dioxin contamination after a fire in the public landfill of Tagarades, which is situated southeast of Thessaloniki, Greece. The aim of this study was to determine the levels of PCDD/Fs and PCBs in food samples of meat, eggs, dairy products and vegetables, collected near the affected area, and to compare them with the usual(More)
The changes in some kinetic properties of pyruvate kinase from the mantle muscle and the hepatopancreas of Patella caerulea, over a time-course of 16 or 8 h of acute hypoxia were studied. Up to the second hour of anaerobiosis PK exhibited changes of the kinetic properties in the direction of activation, whereas in the late stages of anaerobiosis in both(More)
Biodegradable oligolysine and oligoarginine-type homopeptides functionalized with PEG of two different molecular weights interact with insulin, at physiological pH, affording complexes studied by dynamic light scattering, ζ-potential, circular dichroism, FTIR spectroscopy, and isothermal titration calorimetry (ITC). High levels of insulin complexation(More)
