Objectives: The aims of this study were to test whether lightening of the overexposed radiographs improve determination of endodontic files length and whether lightened radiographs are comparable with ideally exposed radiographs. Material and Methods: Four dried human skull coated with soft tissue-equivalent wax used for exposing radiographs of the upper molars. First, the endodontic file was p...

Twenty-eight Brangus cattle were used to determine the effect of copper and selenium supplementation on performance, feed efficiency, composition of fatty acids in Longissimus dorsi (LD) muscle, and cholesterol concentration in serum and in LD muscle and enzymes activities, reduced glutathione (GSH) and oxidized glutathione (GSSG). The treatments were: i) Control, without copper (Cu) and seleni...

The goal of this study was to determine the role of an influx copper transporter, CTR1, in the ototoxicity induced by cisplatin, a potent anticancer platinum analog used in the treatment of a variety of solid tumors. As determined through reverse transcriptase-PCR (RT-PCR), quantitative RT-PCR, Western blot, and immunohistochemistry, mouse CTR1 (Ctr1) was found to be abundantly expressed and hi...

OBJECTIVES 1) to determine zinc and copper levels of contamination in the individual component solutions used to prepare the pediatric total parenteral nutrition mixtures in Argentina; 2) to compare zinc and copper amounts prescribed by the physician with the true amount given to a neonate weighing 1.2 kg and to a child weighing 10 kg, who would receive total parenteral nutrition formulas prepa...

Copper sulfate is widely used as a fungicide and pesticide. Acute copper poisoning rare but potentially lethal in severe cases. can lead to cellular damage of red blood cells, hepatocytes, myocytes. Toxic effects include intravascular hemolysis, acute tubular necrosis and, rhabdomyolysis. A 76-year-old man presented with vomiting epigastric pain. He had ingested copper-containing (about 13.5 g ...
