With the recent interest on the theranostic approach, there has been a renewed interest for alternative radionuclides in nuclear medicine. They can be produced using common production routes, i.e., using protons accelerated by biomedical cyclotrons or neutrons produced in research reactors. However, in some cases, it can be more valuable to use deuterons as projectiles. In the case of Cu-64, sm...
Introduction: Previously, 186Re and 188Re radioisotopes have been produced through appropriate activities, and each of them has been used for therapeutic applications. The 186Re and 188Re have unique properties, which make them proper for the treatment of tumors in different sizes. The long-range 188Re, is suitabl...
Hypertrophy and inflammation of the synovium with various underlying pathologies - such as rheumatoid arthritis, osteoarthritis, haemophilia and spondyloarthropathy - can be treated successfully by radiosynoviorthesis (RSO). For medium-sized joints (shoulder, elbow, wrist, hip and ankle), the radionuclide of choice is rhenium-186. We review the evidence for the efficacy of this local, relativel...
Photocatalytic CO(2) reduction has been studied for two dyads with porphyrin covalently attached to rhenium tricarbonyl bipyridine moieties, and on separate components consisting of [Re(CO)(3)(Picoline)Bpy](+) and either zinc porphyrin or zinc chlorin. TONs decrease in the order: zinc porphyrin + Re > long spacer dyad > zinc chlorin + Re > short spacer dyad.
The pharmacokinetics of 186Re-HEDP, a radiopharmaceutical for palliative treatment of metastatic bone pain, was investigated in 11 patients (17 studies) who suffered from metastatic breast or prostate cancer. Half-life times of 186Re in three blood fractions (whole blood, plasma and plasma water) were 40.1 +/- 5.0, 41.0 +/- 6.0 and 29.5 +/- 6.4 hr, respectively. Time-dependent increase in plasm...
The twoand three-dimensional ~2D and 3D! versions of ALEGRA-HEDP @A. C. Robinson and C. J. Garasi, ‘‘Three-dimensional Z-pinch wire array modeling,’’ Computer Physics Communications, submitted# have been utilized to simulate discrete wire effects including precursor formation in 2D (r-u plane! and nonuniform axial ablation ~3D!. Comparisons made between 2D and 3D simulations indicate that 2D si...
One of the best procedures to prevent haemarthrosis in haemophilia has been radioactive synovectomy (radiosynoviorthesis). Since 1976 we have performed 119 radiosynoviortheses in 110 patients, aged from 3 to 40 years (mean 10), and of whom 71 were under 12 years of age. The knees were injected in 71, elbow in 29, ankles in 16, and shoulders in 3 cases. Clinical results of the procedure gave exc...
Excitation functions, thinand thick-target yields for the Re radionuclides were measured by the activation method on natural tungsten foils for proton energies up to 17 MeV. A new data set has been given for the investigated radionuclides. These results are compared both with the experimental literature values and the ones calculated by the EMPIRE II code (version 2.19). In particular, the atte...
