The present invention provides a novel method for the preparation of .sup.18F-fluoride (18F) for use in radiofluorination reactions. The method of the invention finds use especially in the preparation of 18F-labelled positron emission tomography (PET) tracers. The method of the invention is particularly advantageous where bulk solutions are prepared and stored in prefilled vials rather than being freshly prepared on the day of synthesis. Also provided by the present invention is a radiofluorination reaction which comprises the method of the invention, as well as a cassette for use in carrying out the method of the invention and/or the radiofluorination method of the invention on an automated radiosynthesis apparatus.

or a pharmaceutically acceptable salt or solvate thereof, in combination with other cancer treatments are described, wherein R.sup.1 is halo; R.sup.2 is halo; and Q is CH or N.

New chelators such as H.sub.3L1, H.sub.3L2, H.sub.3L3, H.sub.3L26 and derivatives were synthesized for the complexation of {Al.sup.18F}.sup.2+. These new chelators are able to complex {AI.sup.18F}.sup.2+ with good radiochemical yields using a labeling temperature of 37° C. The stability of the new Al.sup.18F-complexes was tested in phosphate buffered saline (PBS) at pH 7 and in rat serum. AI.sup.18F-L3 and AI.sup.18F-L26 showed a stability comparable to that of the previously reported Al.sup.18F-NODA. Moreover, the biodistribution of Al.sup.18F-L3 and AI.sup.18F-L26 showed absence of in vivo demetallation since only very limited bone uptake was observed, whereas the major fraction of activity 60 min p.i. was observed in liver and intestine due to hepatobiliary clearance of the radiolabeled ligand. The chelators H.sub.3L3 and Al.sup.18F-L26 demonstrated to be a good lead candidates for the labeling of heat sensitive biomolecules with .sup.18F-fluorine and derivatives have been synthesized. We have explored the complexation of {AI.sup.18F}.sup.2+ with new chelators and obtained very favourable radiochemical yields (>85%) using a labeling temperature of 37° C. The stability of the new Al.sup.18F-complexes was tested in phosphate buffered saline (PBS) at pH 7 and in rat serum at 37° C., where AI.sup.18F-L3 and AI.sup.18F-L26 showed a stability comparable to that of the previously reported Al.sup.18F-NODA. Moreover, the biodistribution of Al.sup.18F-L3 and Al.sup.18F-L26 showed high stability, since only very limited bone uptake—which would be an indication of release of fluorine-18 in the form of fluoride—was observed, whereas the major fraction of activity 60 min p.i. was observed in liver and intestines due to hepatobiliary clearance of the radiolabeled ligand. The chelators H.sub.3L3 and H.sub.3L26 demonstrated to be good lead candidates for the labeling of heat sensitive biomolecules with .sup.18F-fluorine and several derivatives have been synthesized.

Nanoparticles and microparticles, and pharmaceutical formulations thereof, containing conjugates of an active agent such as a therapeutic, prophylactic, or diagnostic agent attached to a targeting moiety, such as a somatostatin receptor binding moiety, via a linker have been designed. Such nanoparticles and microparticles can provide improved temporospatial delivery of the active agent and/or improved biodistribution. Methods of making the conjugates, the particles, and the formulations thereof are provided. Methods of administering the formulations to a subject in need thereof are provided, for example, to treat or prevent cancer or infectious diseases.

The invention relates to novel monoclonal anti-alpha-synuclein antibodies. The antibodies can be used for treating a synucleinopathy such as Parkinson's disease (including idiopathic and inherited forms of Parkinson's disease), Diffuse Lewy Body Disease (DLBD), Lewy body variant of Alzheimer's disease (LBV), Combined Alzheimer's and Parkinson disease, pure autonomic failure and multiple system atrophy.

An isotope production system, emanation generator, and process are disclosed for production of high-purity radioisotopes. In one implementation example, high-purity Pb-212 and/or Bi-212 isotopes are produced suitable for therapeutic applications. In one embodiment the process includes transporting gaseous radon-220 from a radium-224 bearing generator which provides gas-phase separation of the Rn-220 from the Ra-224 in the generator. Subsequent decay of the captured Rn-220 accumulates high-purity Pb-212 and/or Bi-212 isotopes suitable for direct therapeutic applications. Other high-purity product isotopes may also be prepared.

The present invention provides compositions and methods for detecting GluA1, as a subunit protein and/or as a GluA1-containing, GluA2-lacking AMPAR complex. The invention further provides composition and methods for detecting and/or diagnosing GluA1-mediated disorders, such as PTSD. The invention further relates to compositions that can be detected using radiological imaging techniques, and processes for performing such imaging techniques using the compositions, to identify elevated GluA1 expression or activity in a subject.
