Transthoracic Biopsy is a complementary diagnostic test used to diagnose lung, pleural and mediastinal injuries. This procedure, performed through puncture with intermittent support of axial images, or with Fluro-CT, in which the control of the needle position is done in real time, according to a minimally invasive method, can be performed in an outpatient setting. The type and size of the needle to be selected...
The authors present a clinical case report, of a 73 year-old female patient, with hypochromic, microcytic anaemia and serum iron deficiency, of two years duration. The out-patient colonoscopic and upper gastro-duodenal endoscopic studies were inconclusive. She presented with a decline in general status, asthenia and anorexia of two months duration, as well as dark stools and tachycardia, four days before hospit...
In the last decades, an increasing number of procedures to remove pollutants from wastewater have been reported. Advanced oxidation processes (AOPs) are one of those technologies used for this purpose, namely, for textile wastewater treatment. AOPs are environmentally friendly methods based on chemical, photochemical or photocatalytical production of hydroxyl radical (HO•). This strong oxidant can react with mo...
The aim of the present study was to investigate the electrochemical degradation of a vinylsulphone reactive dye, C.I. Reactive Orange 16, in the presence of hydrogen peroxide and copper ions. The reaction between these two species leads to the generation of hydroxyl radicals, causing dye oxidation and degradation. The efficiency of dyebath decolorization and dye degradation was evaluated by color removal and CO...
