Effect of E-beam treatment on the chemistry and on the antioxidant activity of lycopene from dry tomato peel and tomato powder.

Tomato powder (TP) and dry tomato peel (DTP) have been previously used in our laboratory as a source of lycopene to manufacture meat products ready-to-eat (RTE) submitted to E-beam irradiation with good technological and sensory results. Present work describes the studies performed in order to investigate the effect of radiation on chemical changes and antioxidant properties of lycopene. DTP and TP were irradiated (4 kGy).

Renal variant of Anderson-Fabry disease and bilateral renal cell carcinoma.

Anderson-Fabry disease (AFd) is an X-linked metabolic disease with clinical manifestations secondary to accumulation of glycosphingolipids in various tissues. We report the first case in which a patient with renal variant of AFd and chronic renal failure developed bilateral conventional renal cell carcinoma. His metabolic disorder was diagnosed only after histopathologic study of the kidney specimen resected because of the tumoral lesion.
