Propylthiouracil (PTU) and methimazole (MMI) are the most commonly used antithyroid drugs. The available data suggest that these drugs may block the thyroid hormone synthesis by inhibiting the thyroid peroxidase (TPO) or diverting oxidized iodides away from thyroglobulin. It is also known that PTU inhibits the selenocysteine-containing enzyme ID-1 by reacting with the selenenyl iodide intermedi...

an Appropriate Basis for Nuclear Worker Compensation? Wakeford (2003) and Little (2003) wrote in response to our comments about the use of A-bomb survivor studies as a basis for U.S. nuclear worker compensation decisions (Wing and Richardson 2002). Wakeford (2003) disagrees with our statement (Wing and Richardson 2002) that there is discrepancy between childhood cancer risk estimates from in ut...

Interlacing causes complications in many image processing tasks. Theoretically, interlacing can be perfectly undone, but there remain a few difficulties in de-interlacing. Aliasing is an inherent artifact due to the interlaced sampling of video data. Interlacing also causes the loss of vertical resolution in the video. Motion in the video scenes need to be modelled accurately for the removal of...

We review the results of our work on the iodine interaction with thioamides, selenoamides, and amides. Complexes with (i) “spoke” or “extended spoke” structures, D · I2 and D · I2 · I2, respectively, (D is the ligand donor) (ii) iodonium salts of {[D2 − I][In]} (n = 3, 7) and {[D2 − I][FeCl4]} formulae and (iii) disulfides of the categories (a) [D − D], (b) {[D−DH][I3]} have been isolated and c...

Voltage-dependent K channels like Shaker use an intracellular gate to control ion flow through the pore. When the membrane voltage becomes more positive, these channels traverse a series of closed conformations before the final opening transition. Does the intracellular gate undergo conformational changes before channel opening? To answer this question we introduced cysteines into the intracell...
