The sodium/iodide transporter (NIS) mediates active I− uptake in thyroid, lactating breast, salivary gland, and stomach epithelial cells. NIS-mediated I− transport is electrogenic with a 2:1 Na+:I− stoichiometry, i.e. when NIS activity is measured electrophysiologically in NIS-expressing oocytes, inward positive currents are recorded upon addition of I− or other anions that are NIS substrates. Howev...

BackgroundBioelectrical impedance analysis (BIA) has been widely used in the evaluation of body composition. Phase angle (PhA) is obtained from the direct measurements of resistive (Rz) and reactive (Xc). Pha and can be interpreted as an indicator of fluid distribution, electric resistance and cellular membrane capacitance of the human body, and is associated with nutritional status. Its screening, and an early intervention in patients with a low PhA, ma...
