This paper reports on the analytical application of the oxidation reaction of [Os(bpy)3]2+ by Mn7+ (MnO4-). The present study developed a very simple, sensitive and selective spectrophotometric method for the determination of manganese in an acidic medium. Three analytical wavelengths were employed in the UV and visible regions at 290, 315 and 480 nm. Beer's law was obeyed up to a concentration...

Tunicamycin, an antibiotic which blocks the formation of N-acetylglucosamine-lipid intermediates, thereby preventing glycosylation of glycoproteins, inhibits the secretion of IgA and IgE by MOPC 315 mouse plasma cells and IR162 rat plasma cells, respectively. At 0.5 microng of tunicamycin per ml, D-[14C]glucosamine incorporation into newly synthesized immunoglobulin was inhibited greater than 9...

Noncytotoxic, MOPC-315 tumor bearer spleen cells were converted to a cytotoxic state by in vitro activation with MOPC-315 stimulatortumor cells.The levelof in vitro cytotoxicity exhibited by activated spleen cells from mice bearing small tumors was similar to that of activated spleen cells from normal mice while that exhibited by activated spleen cells from mice beaming large tumors was much lo...

Sensitive images of low-level, Mpc-sized radio cocoons offer new opportunities to probe large scale intergalactic gas flows outside clusters of galaxies. New radio images of high surface brightness sensitivity at strategically chosen wavelengths of the giant radio galaxy NGC 315 (Mack et al. 1997, 1998) reveal significant asymmetries and particularities in the morphology, radio spectrum and pol...

Cultured spleen cells from normal or MOPC-315 tumorbearing BALB/c mice that were pretreated in vivo with Bacillus Calmette-Guérin(BCG) exhibited in vitro cytotoxicity against MOPC-315 plasmacytoma. In vitro education of BALB/c spleen cells from normal or tumor-bearing mice by cocultivation with mitomycin C-treated MOPC-315 stim ulator cells also resulted in antitumor cytotoxicity. The combinat...
