The in situ oxygen partial pressure in normal and tumor tissues is in the range of a few percent. Therefore, when studying cell growth in 3D culture systems, it is essential to consider how the physiological oxygen concentration, rather than the one in the ambient air, influences the proliferation parameters. Here, we investigated the effect of reducing(More)
Plasma concentrations of homocysteine, cysteine, cysteinylglycine and glutathione were measured using a HPLC technique with fluorescence detection of the derivatives obtained with 7-fluoro-2,1,3-benzoxadiazole-4-sulfonamide (ABD-F). Blood was drawn into chilled EDTA-evacuated tubes. After centrifugation at 4 degrees C without delay, plasma samples were kept(More)
A study of the experimental chemotherapeutic activity of secnidazole as compared to metronidazole is presented, including a summary of toxicity, metabolism, pharmacokinetic studies and preliminary results from clinical trials. Secnidazole is about twice as active as metronidazole against experimental amebiasis, equiactive against trichomoniasis, and(More)
