    Notes: Summary A series of safe, simple and single-staged reconstructions following radical resection of maxillary antral carcinomas with soft tissue involvement is presented. These reconstructions were performed using free triple-folded latissimus dorsi myocutaneous flaps revascularised via the facial vessels. This technique can be safely used in irradiated patients and, when indicated, allows for the administration of early postoperative radiotherapy, thus improving the potential cure rate. Advantages and disadvantages of the technique are discussed.

    Notes: The reaction IO + CH3SCH3 → products (3) was studied at room temperature and near 1 Torr pressure of He, using the discharge flow mass spectrometric technique. The rate constant was found to be k3 = (1.5 ± 0.5) × 10-11 cm3 molecule-1 s-1. CH3S(O)CH3 was detected as a product suggesting the following channel: IO + CH3SCH3 → CH3S(O)CH3 + I. The rate constant of the reaction IO + IO → products (1) was also measured: k1 = (3 ± 0.5) × 10-11 at 298 K and 1 Torr pressure. The atmospheric implication of reaction (3) is discussed. The results indicate that this reaction could be a potential important sink of CH3SCH3 in marine atmosphere.

    Notes: A kinetic study of the reactions of H atoms with CH3SH and C2H5SH has been carried out at 298 K by the discharge flow technique with EPR and mass spectrometric analysis of the species. The pressure was 1 torr. It was found: k1 = (2.20 ± 0.20) × 10-12 for the reaction H + CH3SH (1) and k2 = (2.40 ± 0.16) × 10-12 for the reaction H + C2H5SH (2). Units are cm3 molecule-1 s-1. A mass spectrometric analysis of the reaction products and a computer simulation of the reacting systems have shown that reaction (1) proceeds through two mechanisms leading to the formation of CH3S + H2 (1a) and CH3 + H2S (1b).

    Notes: The reactions of OH radicals with dimethylsulfide (DMS) diethylsulfide (DES), tetrahydrothiophene (THT), and thiophene have been studied at room temperature for DES and THT, at 273, 293, and 318 K for DMS, and at 293 and 318 K for thiophene by the discharge flow EPR technique in a halocarbon wax coated reactor. The following rate constants were obtained at room temperature. For the reaction OH + DMS (1), a very low temperature dependence was noticed.Some additional results concerning the mass spectrometric analysis of the products are also reported.
