Objectives: natural dentofacial changes and that induced by the Thurow modified extra oral appliance (TMEOA) were evaluated in this prospective study. Methodology: the data consisted of fifteen Class II division 1 children 7 to 10 years old, with anterior open bite and hiperdivergent facial pattern treated with the Thurow appliance and of fifteen Class II division 1 children followed longitudinally from 6 to 12 years of age without treatment (Burlington Growth Centre, Toronto University, Canada). The analyses were based in traditional measurements obtained in lateral cephalometric radiographs scanned with the aid of the software Radiocef Studio®. Radiographs were taken in the beginning and after 1 year of treatment for the treated group and at the 6, 9 and 12 years of age for the control group. Results: the data analysis showed that the TMEOA significantly reduced the SNA, ANB, AOBO, SNPOc SNPM, SGO/NMe, OJ e OB. On the other hand the appliance did not interfere with the SNB e SNPP. The natural growth promoted significant change in the ANB, AOBO, SNPOc, OJ e OB from 6 to 9 years and in the SNB, SNPOc e SGo/NMe from 9 to 12 years. The restriction of the maxillary growth (SNA), reduction of the skeletal discrepancy (ANB) and the reduction of the overjet (OJ) were significant with the treatment considering the natural growth as verified in the control group. Conclusion: the TMEOA corrected the skeletal Class II malocclusion by maxillary restriction, reducing the overjet, closing the anterior open bite and decreasing both the hyper divergent facial pattern and mandible plane inclination.

The consumption of carotenoid-rich vegetables such as tomatoes and tomato sauces is associated with reduced risk of several chronic diseases. The predominant carotenoids in tomato products are in the (all-E) configuration, but (Z) isomers can be formed during thermal processing. The effect of cooking time (15, 30, 45 and 60 min) and the addition of extra virgin olive oil (5% and 10%) on the carotenoid extractability of tomato sauces was monitored using liquid chromatography-tandem mass spectrometry (LC-ESI-MS/MS) and LC-ultraviolet detection (LC-UV). The thermal treatment and the addition of extra virgin olive oil increased the levels of antioxidant activity, total carotenoids, Z-lycopene isomers, -carotene and -carotene. These results are of particular nutritional benefit since higher lycopene intake has been associated with a reduced risk of lethal prostate and a reduction of prostate-specific antigen (PSA) levels. Moreover, -carotene has been reported to suppress the up-regulation of heme oxygenase-1 gene expression in a dose dependent manner and to suppress UVA-induced HO-1 gene expression in cultured FEK4.
