Slow Inward Current, Thallium Intoxication, Voltage Clamp, Available Intracellular Energy To conclude our investigation of thallium effects on cardiac tissues, we studied the slow inward current of sheep cardiac Purkinje fibres exposed to 10“7 to 105 m Tl+ for extended periods of up to 80 min. Our previous results had suggested a possible involvement of the slow inward current during thallium i...

Fifty-two patients with suspected coronary artery disease underwent coronary angiography, thallium-201 myocardial imaging, and ECG-gated blood pool ventriculography at rest and at maximal exercise. In 11 patients without coronary artery disease, all thallium images were normal. The resting ejection fraction (EF) was normal in all 11 patients and increased during exercise in six, was unchanged i...

The method is based on the separation of Tl(I) as Tl(2)HPMo(12)O(40), stripping of the molybdate, and measurement of the peak current in differential-pulse polarography of the molybdenum. The calibration graph is linear over the range 2-12 ppm of thallium. The relative standard deviation is 1.2% (7 replicates each containing 500 microg of thallium). The current due to reduction of the molybdenu...

At this study, thallium (I) ion-imprinted polymer, as a novel sorbent for Tl (I) and comparison with Tl(III) ion-imprinted polymer has been synthesized. This sorbent for preconcentration and solid-phase extraction of Tl(I) ions from aqueous solutions, used. Through preparing the binary complex of Tl(I) ions with 5, 7-dichloroquinoline-8-ol (DCQ) the particles of thallium (I) Ion-Imprinted P...

PURPOSE Late enhancement magnetic resonance imaging (MRI) was compared with thallium-201 rest-redistribution single photon emission computed tomography (SPECT) in patients with reduced left ventricular (LV) function and prior myocardial infarction (MI). BACKGROUND Hyperenhancement on contrast cardiac MRI using gadolinium diethylenetriamine pentaacetic acid (Gd-DTPA) has been reported to ident...
