Imazosulfuron, 1-(2-chloroimidazo[1,2-alpha]pyridin-3-ylsulfonyl)-3- (4,6-dimethoxypyrimidin-2-yl)urea, is a new post-emergence sulfonylurea herbicide applied once per growing season, highly active at low application levels, used to control most annual and perennial broad-leaf weeds and sedges in paddy rice (75-95 g AI ha-1) and turf (500-1000 g AI ha-1),(More)
Purpose. To assess the response rate, survival, and toxicity of Taxol®(paclitaxel) as 1‐h infusion plus doxorubicin as first‐line treatment for patients with metastatic breast cancer (MBC). Patients and methods. Seventy‐six patients with untreated MBC were recruited. All of them had measurable disease and were evaluable for toxicity. Fifty‐five percent of(More)
Uracil and tegafur (in a molar ratio of 4:1 [UFT]) has proven activity against breast cancer and is delivered in an easy-to-administer oral formulation. Orzel, which combines UFT with the oral biomodulator, calcium folinate, may provide even greater antitumor efficacy against breast cancer. Here, we describe the preliminary results of this phase II trial(More)
Reversed-phase liquid chromatography (LC) is used to determine a relatively new sulfonylureic herbicide, imazosulfuron, 1-(2-chloroimidazo-[1,2-a] pyridin-3-ylsulfonyl)-3-(4,6-dimethoxy-2-pyrimidinyl)-urea (TH-913), in drinking water and in soil. TH-913 is extracted from water using solid-phase extraction on C18 bonded silica. Soil samples (20 g) are(More)
Disposable, ready-to-use cartridges filled with a macroporous diatomaceous material are used to extract in a single step fungicide residues with dichloromethane from aqueous acetone extracts of vegetables. This procedure takes the place of some functions (such as separating funnel partition, drying over anhydrous sodium sulphate and clean-up) usually(More)
Eleven quinolone antibacterials have been analyzed by HPLC. The effects of different pH values and organic modifiers on chromatographic behaviour are discussed. Moreover the influence on separation mechanism of different counter-ions at various concentrations in the eluent has been investigated. Two different chromatographic methods have been selected, that(More)
