摘要:
Fluoroalkanes such as fluoromethane labeled with 17F are produced by contracting 17F labeled F¿2? with alkanes, preferably methane, substituted or unsubstituted alkenes, or substituted or unsubsituted alkynes in the presence of a metal oxide catalyst, preferably a silver oxide catalyst, to produce the ?17¿F labeled fluoroalkane. The 17F may be produced by irradiating 20Ne with protons, preferably having an energy of about 11 MeV and produced by a cyclotron. The 17F labeled fluoromethane or fluoroalkanes may be produced continuously. A method for determining the location of an 17F labeled tracer includes generating an 17F labeled fluoroalkane, administering the 17F labeled fluoroalkane to a test subject, and scanning the test subject with a radiosensitive detector such as a positron emission tomography scanner.
摘要:
A controlled release agricultural absorbent based product including particles of an absorbent material containing capillaries/voids between 10-200 microns in cross-sectional diameter which is impregnated in an amount of 40-95 % of the capillaries/voids volume with an agriculturally beneficial material selected from the group consisting of fertilizers, insecticides, herbicides and fungicides, being produced by a process shown in figure 1 including steps of: a) introducing water (6) to particles of absorbent material (4) to result in absorption of water within the absorbent material, b) heating the absorbent particles and water (5, 7) to transform the water within the absorbent particles to steam, c) introducing the heated absorbent particles to an agriculturally beneficial material in aqueous solution (1, 2) to essentially saturate the absorbent particles with the agriculturally beneficial material (3, 8), d) granulating the combination of agriculturally beneficial material and saturated absorbent particles to solidify and harden the mixture (9, 10, 11, 12), resulting in the agglomeration of absorbent particles into granules, and e) drying the granules (13).
摘要:
Biologically active 19-nor vitamin D analogs substituted at C-2 in the A-ring with an ethylidene or an ethyl group. These compounds have preferential activity on mobilizing calcium from bone and either high or normal intestinal calcium transport activity which allows their in vivo administration for the treatment of metabolic bone diseases where bone loss is a major concern. These compounds are also characterized by high cell differentiation activity.
