An automated radiopharmaceutical production and quality control system includes a particle accelerator, a radiopharmaceutical micro-synthesis subsystem, and quality control subsystem. The micro-accelerator of the improved biomarker generator is optimized for producing radioisotopes useful in synthesizing radiopharmaceuticals in quantities on the order of multiple unit doses, allowing for significant reductions in size, power requirements, and weight when compared to conventional radiopharmaceutical cyclotrons. The radiopharmaceutical micro-synthesis subsystem encompasses a small volume chemical synthesis system comprising a microreactor and/or a microfluidic chip and optimized for synthesizing the radiopharmaceutical in small quantities, allowing for significant reductions in processing time and in the quantity of radioisotope required. The automated quality control subsystem is used to test the composition and characteristics of the radiopharmaceutical to ensure that it is safe to inject.

Described herein are Tz/TCO-based pretargeting strategies using an Al[.sup.18F]-NOTA-labeled tetrazine radioligand. This imaging strategy enables delineation of cancer at earlier time points compared to other imaging strategies and further decreases the radiation dose to healthy tissues compared to directly labeled antibodies. Al-based .sup.18F imaging of small molecules, such as tetrazine, has not been previously achieved due to the decomposition of tetrazine during radiofluorination. Radiofluorination is advantageous over other radiolabeling methods because, in addition to having a shorter half-life, .sup.18F is more readily available to produce and therefore integrated into hospital workflows.

A breath test and a breath test method for diagnosing abnormal gastric emptying using a .sup.13C labeled breath test meal by identifying the time of maximum excretion of .sup.13CO.sub.2 in the breath samples. The test and test method include supplying a subject with the breath test meal, collecting a breath sample of the subject at a plurality of time points after the subject consumes the meal, generating measurements of .sup.13CO.sub.2 excretion from the breath samples, identifying a time T.sub.max at which .sup.13CO.sub.2 excretion is maximal, comparing T.sub.max to a cut-off value. The subject may be diagnosed as having delayed gastric emptying if T.sub.max is greater than the T.sub.max cut-off value.

Systems and methods including a material that emits high energy beta particles to destroy cancer cells contained in cancerous tumor or tissue. Electronic neutron generators produce neutrons with energies that have a high probability to interact with the material yttrium-89 to produce yttrium-90. Yttrium-90 emits beta radiation with a maximum energy of about 2.25 MeV and a half-life of about 64 hours, which decays to stable zirconium. Stable yttrium-89 can be directly placed in or around cancerous tissue and irradiated with neutrons in the 0.1-15 KeV energy range to produce significant amounts of yttrium-90. The beta radiation emitted by yttrium-90 will primarily destroy the more radiation sensitive cancer cells within the range of the beta particles. The resulting zirconium isotope is not radioactive such that no further radiation is released. A low probability gamma is also created that will assist in cancer cell destruction.

The present invention provides compositions for treating or preventing cancer and methods of using and making the compositions. The compositions comprise herpes simplex viruses comprising recombinant herpes simplex virus genomes. Further provided are recombinant herpes simplex virus genomes, viruses comprising the recombinant herpes simplex virus genomes, and cancer vaccines and other compositions comprising the viruses.

Infusion system configurations and assemblies facilitate routing of infusion circuit tubing lines. Tubing lines are routed into and out from compartments of a shielding assembly for the infusion system, at locations which prevent kinking and/or crushing of the lines, and/or provide for ease in assembling the circuit. A plurality of the lines may be held together by a support frame to form a disposable infusion circuit subassembly, that can further facilitate routing of the lines.

The present invention relates to compounds that are useful as metal ligands and which either contain a molecular recognition moiety or can be bound to a molecular recognition moiety and methods of making these compounds. Once the compounds that contain a molecular recognition moiety are coordinated with a suitable metallic radionuclide, the coordinated compounds are useful as radiopharmaceuticals in the areas of radiotherapy and diagnostic imaging. The invention therefore also relates to methods of diagnosis and therapy utilising the radiolabelled compounds of the invention.

A method of labelling biological molecules with .sup.18F, via attachment of fluorine to a metal complex, where the metal complex is conjugated to the biological molecule. The invention highlights the incorporation of hydrogen bonding (H-bonding) into the metal complex scaffold, and how this can be utilised to improve the kinetics of fluoride incorporation. Also provided are pharmaceutical compositions, kits and methods of in vivo imaging.

This invention relates the use of cortisol blockers (glucocorticoid receptor [GR] antagonists) for the treating or preventing treatment resistant prostate cancer, treating or preventing neoplasia, and treating or preventing infection related to acute or chronic injury or disease.
