Introduction.-It has been shown earlierl 2 that the synthesis of the isoprenoid, rubber, by a rubber-bearing plant, guayule (Parthenium argentatum), involves acetate as an, intermediate. Not only does the administration of acetate to this plant result in a net increase in the amount of rubber formed, but, in addition, rubber synthesized by plants supplied with doubly C"4-labeled acetate possess...

and Summary.-Analysis of the electron spin resonance (ESR) of a 'y-irradiated single crystal of L-tyrosine-HCl reveals a free radical formed by loss of an H from the hydroxyl group attached to the ring. Principal g values of the radical are g. = 2.0023 A 0.0005, g, = 2.0067 + 0.0005, and g, = 2.0045 ± 0.0005, with gx perpendicular to the plane of the ring and g, along the CO bond to the ring. A...

Syringe exchange programs in Brazil: preliminary assessment of 45 programs.

The present study aims to evaluate the current operation of Brazilian syringe exchange programs (SEP). After consulting national and regional networks of people working in projects/programs aiming to reduce drug-related harm, we identified 134 potential participant programs. Unfortunately, only 45 SEPs answered a survey, even after repeated attempts. The survey addressed: coverage, funding, pro...
