A three years (2008, 2009, and 2011) open field experiment was conducted to study the effect of growing methods (organic and conventional) on the tomato yield components (Brix°, carbohydrate, organic acid, lycopene, and total polyphenols). Significantly higher Brix°, carbohydrate-, and lycopene content was found in conventional production. In spite of this, total phenolic content of tomato fruits was significantly higher in organic production. Our experiences show that it is probable, that the techniques used in the cultivation of organic crops-no artificial nutrients-could activate natural defence mechanisms in tomato plants, by increasing content of total polyphenol in the fruits.

Background: Metabolic syndrome occurs more often among people living in poorer social conditions. The health status of the largest minority ethnic group in Hungary lags in many aspects behind that of the general population. Methods: To estimate the prevalence of metabolic syndrome a screening was initiated in the city of Gyor among subjects aged 20-70 years who declared themselves as Gypsy. Subjects with known diabetes and cardiovascular disease were excluded. The diagnosis of metabolic syndrome was based on the ATP-III criteria. Results: Among the 77 individuals screened (35 men, 42 women, age 46.9 ± 10.6 years, × ± SD) diabetes mellitus was found in 14 cases (18.2 %), and pre-diabetes (impaired fasting blood glucose (IFG) or impaired glucose tolerance (IGT) could be diagnosed in further 14 cases (18.2 %). Individual components of the metabolic syndrome occurred as follows: hypertension in 47 subjects (61.0 %), abnormal waist circumference in 40 individuals (51.9 %), abnormal HDL-cholesterol in 39 cases (50.6 %), abnormal triglycerides in 35 individuals (45.5 %) and abnormal fasting blood glucose in 15 subjects (19.5 %). Within the cohort metabolic syndrome could be diagnosed in 39 individuals (50.6 %) without a signifi cant gender difference (males 20/35 = 57.1 %; women: 19/42 = 45.2 %, p>0.05). Conclusion: The occurrence of metabolic syndrome and that of glucose intolerance is high among adult Gypsy people in Hungary. In order to recognise cardio-metabolic risks and to prevent their cardiovascular consequences, continuous health promotion and adequate medical care should be provided for the Gypsy population in Hungary.

During the vine ripening of tomato fruits (Solanum lycopersicum L.), the change in antioxidant content and color was studied under two different solar exposures. An experiment was carried out in 2008 and 2009 to determine how color evolution, surface temperature, and antioxidant content of tomato fruits were influenced by fruit position and exposure on trellised tomato plants. Trellised rows were oriented so that non-shaded fruits were subjected to full solar irradiation from 0900 HR to 1600 HR, whereas shaded fruits were completely shaded during the same time period. A significant difference (P = 0.001) between fruit surface temperatures of shaded or non-shaded fruits was observed. The more direct solar irradiation the fruits were exposed to, the higher the fruit surface temperatures increased. At 1400 HR, only the average temperature of non-shaded fruits was significantly higher (7.0 and 9.3 °C in 2008 and 2009, respectively) than the air temperature. At the end of the ripening process, color change of non-shaded fruits showed significantly higher CIELab hue compared with shaded fruits. A close negative correlation (R2 = 0.51) was detected between the hue color parameters and the cumulative fruit surface-air temperature difference of non-shaded fruits, but in the case of shaded fruits, there was only a weak (R2 = 0.29) correlation. Solar exposure had a great effect on the antioxidant content of tomato fruits. A higher fruit surface temperature resulted in significantly less lycopene and more polyphenols and ascorbic acid content in tomato fruits. Source

Background - The Global Burden of Disease Study has been publishing its reports since the early 1990's. The last one from 2010 covers 291 diseases, and 67 risk factors for 187 countries. Aims - Presenting examples of the Hungarian health burden status the authors advocate the use this unique data source. Methods - The authors downloaded the 1990 and 2010 data for Hungary from the Global Burden of Disease Study website. To quantify the economic burden they calculated the change in GDP related to the absence from work as a consequence of risks and diseases. Results - In the publication the authors presented some of the versatile utilization methods of the GBD data and the data visualization tools available on GDB's website. In 2010 the DALY for Hungary was 3,714,900 years which is the 84% of the country's DALY in 1990. The most Years Lived by Disability was caused by musculoskeletal disorders (YLD: 28.4%), while cardiovascular and circulatory diseases caused the most Years of Life Lost (YLL: 40.3%). In 2010 the dietary risk was the leading risk factors in Hungary accountable for 840 thousand of life years lost which economic cost was over 950 milliard Hungarian forints. Conclusions - The use of the result provided by the Global Burden of Disease Study can significantly contribute for planning and evaluating interventions to promote healthy lifestyle, to advance supporting living conditions, and to distribute health care capacity efficiently. © 2015 LAM.

Tomato fruit ripening is a complex, genetically programmed process that culminates in dramatic changes in texture, color, flavor, and aroma of the fruit flesh. The characteristic pigmentation of red ripe tomato fruit is the result of the de novo synthesis of carotenoids, mainly lycopene and β-carotene, which are associated with the change in fruit color from green to red as chloroplasts are transformed to chromoplasts. The aim of this study was to examine the effect of ripening conditions on color development and antioxidant content. Detached tomato fruit stored at 15 and 30 °C and vine-ripened fruits were studied to characterize the ripening process by Hue (8) index (CIELab color system), which is strongly influenced by the circumstances of ripening. Total polyphenols, ascorbic acid, and lycopene content of tomato fruits were analyzed at the end of the experiment. Changes in the color of fruit stored at 15 °C and vine-ripened fruit showed significantly higher a* compared with fruit stored at 30 °C. Storage temperature influenced positively ascorbic acid and negatively lycopene content, whereas total polyphenols did not show differences among the different ripening conditions. Source
