55 to 109.67 mg equivalents of ascorbic acid/g fresh weight. For both two solvents, Bejo exhibited the highest this website phenolic content and total antioxidant activity, while Baydh El Hamam presented the lowest. A positive linear correlation between total antioxidant activity and phenolic contents was observed (R-2 = 0.83; R-2 = 0.74 for acetone/H2O and methanol/H2O, respectively).

The antioxidant activity of acetone/H2O and methanol/H2O extracts was carried using DPPH

radical-scavenging activity and reducing power. These results showed that dates had strongly scavenging activity on DPPH reaching 90.12% in methanol/H2O from Deglet Nour. Whereas, acetone/H2O showed the best reducing power which Bejo was significantly higher than the other varieties.

This study demonstrates the potential antioxidant activity with Tunisian date, that we can use these natural extracts as food additives in replacement of synthetic compounds. (C) 2012 Elsevier B.V. All rights reserved.”
“Chlorination of 3,6-di-tert-butyl-1,2-benzoquinone in a two-phase catalytic system (CH(2)Cl(2), HCl- H(2)O, H(2)O(2), Bu(4)NCl) led to halogen addition at the C=C bond, and subsequent dehydrochlorination of the adduct gave 3,6-di-tert-butyl-4-chloro-1,2-benzoquinone. Chlorination of the latter

afforded 3,6-di-tert-butyl-4,5-dichloro-1,2-benzoquinone.”
“Objectives: Hybrid aortic arch repair procedure was introduced to reduce invasiveness in high-risk Stem Cell Compound Library patients with aortic arch pathology. The good results are expanding its application, but endoleak, particularly

17DMAG purchase type I, remains its Achilles’ heel.

Design: We describe our experience with hybrid treatment of aortic arch diseases focussing on techniques and results to avoid type I endoleak.

Materials and Methods: A total of 15 high-risk patients with zone 0-2 aortic arch pathology underwent supra-aortic debranching on ascending aorta and proximal aortic arch reinforcement with a Dacron prosthesis. Metachronously, the procedure was completed with endovascular stent grafting (ESG).

Results: Median age was 70 years with a mean European System for Cardiac Operative Risk Evaluation (EuroSCORE) of 12.7 +/- 6.8. One patient died between aortic debranching and ESG. Mean time between surgical debranching and ESG was 32 +/- 27.7 days. No major neurological events occurred. Mean length of the landing zone for ESG was 3.8 +/- 0.8 cm. Computed tomography (CT) angiography scan performed soon after operation, and at 3, 6, and 12 months did not show any type I endoleak.

Conclusions: Supra-aortic debranching on ascending aorta with proximal aortic arch reinforcement is a useful step to ensure a safe landing zone for ESG, reducing risk early to midterm of endoleak. Longer term follow-up is required to confirm the viability of this technique. (C) 2010 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved.
