Rat liver mitochondria are much more susceptible to protein oxidation induced by paraquat than plant mitochondria. The unsaturated index and the peroxidizability index are higher in rat than in potato tuber. The levels of superoxide dismutase and glutathione reductase are concurrent with the different sensitivities to paraquat, with higher activities in(More)
Acquired perforating collagenosis (APC) is a rare perforating dermatosis characterized by transepidermal collagen elimination. We describe a 65-year-old patient, with long-standing type 2 diabetes mellitus and a 2-year history of itchy hyperkeratotic nodules situated on the back, who was subsequently diagnosed with APC. Treatment included topical(More)
OBJECTIVE To retrospectively analyze the safety and efficacy of transjugular intrahepatic portosystemic shunting (TIPS) using covered stents in children. MATERIAL AND METHODS We present 6 children (mean age, 10.6 years; mean weight, 33.5kg) who underwent TIPS with 8mm diameter Viatorr(®) covered stents for acute (n=4) or recurrent (n=2) upper digestive(More)
Ca(2+)-sensitive electrode as a practical approach is used to follow Ca(2+) changes in the medium and particularly useful to study mitochondrial Ca(2+) uptake (or release); this method permits the continuous recording of Ca(2+) movements through the mitochondrial inner membrane. In this chapter, it is described how to prepare a Ca(2+)-sensitive electrode,(More)
