چکیده
The current study was performed to evaluate the efficacy and toxicity of a chemotherapy treatment using melphalan administered over a 24-h period with individual adapted dosing in advanced ovarian cancer. Melphalan was infused intravenously with an automatic infusion pump over a 24-h period. The schedule was repeated every 28 days for a maximum of 6 cycles. The initial administered dose was 25 mg/m2. Drug adjustment was then made using a population approach, with the aim of constraining the overall area under the plasma concentration-time curve within 2.0-2.5 mg • h/l. A total of 96 courses of chemotherapy was administered. The toxicity profile did not differ greatly from that reported after a 1-h infusion and was acceptable in such a heavily pretreated patient population. Twenty-five patients were assessable for response and survival. Four (16%) partial responses were observed, which lasted 9, 10, 13 and 37 months, respectively. Three patients experienced stable disease during 8, 14 and 22 months, respectively. The 1and 2-year survival rates were 18% and 6%, respectively. At the time of analysis, two patients remained alive with progressive disease at 22 and 37 months, respectively. In conclusion, melphalan administered over a 24-h period in platinumand taxane-resistant ovarian cancer patients appeared to provide some clinical benefits with manageable toxicity. Based on these results, future studies comparing melphalan administered over a 24-h period and oral melphalan administrations will be scheduled.

A PdPt (10 wt% Pt) catalyst is used to replace platinum at the cathode of a PEMFC MEA whereas pure palladium is used as the anode catalyst. The catalysts are deposited on commercial carbon woven web and carbon paper GDLs by plasma sputtering. The relations between the depth density profiles, the electrode support and the fuel cell performances are discussed. It is shown that the catalyst gradie...

Two patients with ankylosing spondylitis were found to have IgA nephropathy and leucocytoclastic cutaneous vasculitis. Immunofluorescence showed perivascular deposition of IgA in the skin of one patient and in the mesangium of both patients. Such an association has been reported only once before. This supports the concept of abnormal IgA immune stimulation in the pathogenesis of ankylosing spon...
