OBJECTIVE To investigate the effectiveness and side effects of oral versus pulse cyclophosphamide (CYC) in combination with corticosteroids (CS) in the treatment of systemic Wegener's granulomatosis (WG). METHODS Patients with newly diagnosed systemic WG were enrolled in a prospective, randomized trial. At the time of diagnosis, prior to randomization,(More)
The metabolism of docetaxel by human liver microsomes was investigated in vitro and compared with that of paclitaxel. A main docetaxel metabolite was generated by human liver microsomes in the presence of NADPH: retention time in high pressure liquid chromatography and its ion fragmentation in mass spectrometry were identical to those of the authentic(More)
Biliary, plasma, and urinary disposition of paclitaxel and paclitaxel metabolites were determined simultaneously in a patient with percutaneous biliary drain. The complete chemical structures of the major metabolites were established by mass spectrometry and NMR spectroscopy. A nonlinear elimination model was indicated by the fact that the rate of biliary(More)
The metabolism of paclitaxel and docetaxel by human liver microsomes was investigated in vitro. The main metabolite of paclitaxel formed in vitro was the 6 alpha-hydroxypaclitaxel: its formation largely exceeded the formation of other metabolites hydroxylated on the lateral chain by rat liver microsomes and initially characterized in rat bile. In contrast,(More)
Reversed-phase high-performance liquid chromatography/mass spectrometry (LC/MS), with an atmospheric-pressure chemical ionization (APCI) interface, has been applied to the identification of metabolites and derivatives of paclitaxel (taxol) in plasma and urine of patients treated with this new anticancer drug. Protonated molecules with substantial(More)
Dissolved organic carbon (DOC) export from soils can play a significant role in soil C cycling and in nutrient and pollutant transport. However, information about DOC losses from agricultural soils as influenced by management practices is scarce. We compared the effects of mineral fertilizer (MF) and liquid hog manure (LHM) applications on the concentration(More)
Even at the prototype stage, experts were saying the technology was obsolete. Yet, in the face of tepid consumer response, the company stubbornly kept increasing production capacity and developing new models. By the time it was finally killed, the initiative had cost the company an astounding $580 million and had tied up resources for 14 years. The product(More)
OBJECTIVE To study the nature and incidence of gastrointestinal (GI) manifestations in polyarteritis nodosa (PAN) and Churg-Strauss syndrome (CSS) and define their therapeutic and prognostic implications. METHODS Fifty-three patients (29 males, 24 females) affected with PAN or CSS and followed in our institution were included in a retrospective study.(More)
When renal insufficiency occurs in classical antineutrophil cytoplasm antibody- (ANCA) associated vasculitides, histological examination usually finds pauci-immune focal segmental glomerulonephritis. We report on 2 cases of histologically proven necrotizing vasculitis associated with IgA nephropathy. Concomitant vasculitis and IgA nephropathy has only(More)
The selective, high-efficacy 5-HT(1A) receptor agonist, (3-chloro-4-fluoro-phenyl)-[4-fluoro-4-[[(5-methyl-pyridin-2-ylmethyl)-amino]-methyl]piperidin-1-yl]-methanone (F 13640) has been reported to produce long-term analgesia in rodent models of chronic nociceptive and neuropathic pain; it also preempts allodynia following spinal cord injury. Here, rats(More)
