Abstract: An assembler which limits the amount of torque that may be applied to a brachytherapy cartridge magazine when its cap is threaded onto same. The assembler is constructed so that the brachytherapy cartridge will rotate within the assembler before a destructive torque is applied while the cap and cartridge magazine are screwed together.
Abstract: Aluminum, boron and silicon were identified as potential leachables from borosilicate glassware and a silica based QMA during handling of aqueous 18F. The addition of only 0.4 ppm aluminum as AlCl3 in the eluent vial resulted in a strong reduction in the labeling yield of a model [18F]fluoride SN2 reaction (from 80 to 40% incorporation). The addition of boron as KBO2 and silicon as NaSiO3 did not result in any significant decrease in labeling yield. Interestingly, there was an interaction effect between AlCl3 and KBO2 in which the negative effect from AlCl3 on labeling yield was counteracted by KBO2. The present invention demonstrates that aluminum and boron from borosilicate glassware have a strong influence on the labeling yield in nucleophilic SN2 reactions with n.c.a [18F]fluoride.

Abstract: A transport unit includes a plurality of permanent magnets arranged to provide a magnetic holding field for protecting hyperpolarized gas during storage and/or transport. The permanent magnets are configured in a relatively light weight manner to project a substantially cylindrical magnetic holding field or spherical holding field in space. The magnet arrangements can include primary magnets and field shaping secondary magnets which act to enlarge the region of homogeneity. The permanent magnet arrangement can also be provided with a cylindrical shaped flex sheet magnetically activated to provide the magnetic holding field. The permanent magnet arrangements do not require disassembly to insert or remove one or more containers of hyperpolarized gas in or out of the transport unit.

Abstract: In certain embodiments, methods of the present invention obtain dynamic data sets of an NMR spectroscopy signal of polarized 129Xe in a selected structure, environment, or system. The signal data can be used to evaluate: (a) the physiology of a membrane or tissue; (b) the operational condition or function of a body system or portion thereof (when at rest or under stimulation); and/or (c) the efficacy of a therapeutic treatment used to treat a diagnosed disorder, disease, or condition. Thus, the present invention provides methods for screening and/or diagnosing a respiratory, cardiopulmonary disorder or disease such as chronic heart failure, and/or methods for monitoring the efficacy of therapeutics administered to subject to treat the disorder or disease.
