Background This study evaluated the use of dietary vitamin E and polyphenols on growth, immune and oxidative status of weaned pigs fed peroxidized lipids. A total of 192 piglets (21 days of age and body weight of 6.62 +/- 1.04 kg) were assigned within sex and weight blocks to a 2 x 3 factorial arrangement using 48 pens with 4 pigs per pen. Dietary treatments consisted of lipid peroxidation (6% edible soybean oil or 6% peroxidized soybean oil), and antioxidant supplementation (control diet containing 33 IU/kg DL-alpha-tocopheryl-acetate; control with 200 IU/kg additional dl-alpha-tocopheryl-acetate; or control with 400 mg/kg polyphenols). Pigs were fed in 2 phases for 14 and 21 days, respectively. Results Peroxidation of oil for 12 days at 80 degrees C with exposure to 50 L/min of air substantially increased peroxide values, anisidine value, hexanal, and 2,4-decadienal concentrations. Fee...

222Rn is formed by the decay of 226Ra , then decays into 218Po and 214Po . Po ions electrostatically produced can be collected using a camera with a polarized high voltage then decays 218Po 214Pb particles emitting at 6.003 keV and thereafter decays 214Po 210Pb emitting particles at 7.687 keV. By measuring the concentration of these alpha particles in the camera can determine the concentration of radon in the air in an indirect way . The prototype has been developed using a measuring chamber 2 L stainless steel of a S3204 -09 PIN diode ( Hamamatsu ) bare body as alpha-particle detector . The camera and diode are polarized with a source of high voltage ( +500 V ) to collect ions and detect Po alpha particles that are then produced in the decay chain . Operations and digital functions are implemented on a PIC18F4550 microcontroller and the device has an internal USB module communication fo...
