Nitrogen radio

Although use of radio and stable isotope labels involving the trio of covalently-bonded nitrogenous functions in 3 and in 78, provided evidence that isocyano is the precursor of the isothiocyano and formamido groups [30, 81], it remains to be shown that a biosynthetic equivalent of the in vitro chemically-proven fusion process between isocyano and free sulfur (e.g., cf. Introduction) exists in the cells of sponges. In marine biota, various ionic forms of sulfur in a number of oxidation states, as well as organo-polysulfides are known. However, any association with the isonitrile group and a sulfated species has yet to be established. 

Vesicants are also systemic agents and readily pass through the skin to affect susceptible tissue including those that produce blood. For this reason they are often described as radio-mimetic poisons. In severe cases, systemic effects can include cardiovascular shock and multiorgan failure. Nitrogen vesicants can also cause central nervous system depression and cardiovascular shock. Both sulfur and nitrogen vesicants are carcinogenic.

By studying radio and optical spectra from HII regions and planetary nebulas, to be discussed immediately below, we may establish the abundances of several elements, in particular, helium, absent from the solar spectrum, a point of great cosmological significance, but also nitrogen and oxygen. 

The production of human (Cu,Zn)-SOD by genetic engineering could make sufficient amounts available for a further testing of the promising applications in auto-inunune and inflammatory diseases, and as an adjuvant in the radio- and chemotherapy of certain types of tumors. In this respect the hemolysis observed as a secondary effect in patients treated with nitrogen mustards could be ascribed to a striking reduction of the (Cu,Zn)-SOD levels in their erythrocytes...

Tellurium, evaporated from a crucible, reacted with trifluoromethylthio radicals, generated from bis[trifluoromethyl] disulfane in a radio-frequency glow discharge, in a vessel equipped with a cold finger chilled with liquid nitrogen and evacuated to 0.001 torr. Trap-to-trap distillation of the material that condensed in the cold finger produced bis[trifluoromethylthio tellurium. The thermally unstable compound condensed in the - 45° trap4.
