Abstract: A manifold system allows for the movement of a radioactive fluid from a container to a treatment balloon or other device, and the withdrawal of the radioactive fluid from the treatment device. The system allows for the convenient movement of the fluid, with minimal radiation exposure for those using the system. The manifold system is particularly useful in the use of radiation to prevent restenosis of arteries.

Abstract: A packaging system and method is provided which will substantially retard or reduce the caking of powdered, crystalline, or granular organic and inorganic cakable chemical compounds and mixtures thereof. Such retardation and reduction in caking enhances the free flowability and scoopability of the compound. The packaging system and method comprises a moisture impermeable container which may include a moisture impermeable cover which closes the container, providing a moisture tight seal to close the container, and desiccant. The compound can be placed directly into the container or into a moisture permeable bag which is sealed after the compound has been placed therein. The bag is filled or sized so that there will be a void space in the container once the container is closed. The desiccant is placed in the void space. The drum may be a fiber board drum having a moisture impermeable liner, such as an aluminum liner. The cover is preferably a plastic cover.

Abstract: This invention relates to radiolabeled peptide compositions for radiopharmaceutical use and, more specifically, to radiolabeled peptides for diagnostic or therapeutic use having an unmodified carboxy terminal amino acid. The radiopharmaceutical composition may be used for targeting a selected biological site. The radiolabeled peptide is characterized by having its carboxy terminal amino acid in its carboxylic acid form and the peptide is coupled to a diagnostic or therapeutic radionuclide by a chelating agent. The radiopharmaceutical composition preferably comprises a radiolabeled peptide selected from the group consisting of somatostatin, an analog of somatostatin, a derivative of somatostatin and peptides capable of binding to the somatostatin receptor, where the peptide is coupled to a diagnostic or therapeutic radionuclide by a chelating agent has its carboxy terminal amino acid in its carboxylic acid form.

Abstract: A process is described for the synthesis of nalbuphine. The process results in a product having very low levels of the undesirable .beta.-epimer. The process is a five-step synthesis that begins with a compound such as an N,O.sup.3 -bis (alkoxycarbonyl) -14-hydroxynormorphinone.

Abstract: The invention relates to a reservoir for at least one capsule for oral administration which comprises a substance which is dangerous for the environment, in particular a radioactive composition, which reservoir can be enclosed within an at least substantially cylindrical shielding sleeve, has a closed bottom and can be closed at its open upper end by means of a cap, the reservoir internally comprising a plurality of longitudinal ribs. The reservoir is prefereably constructed so that it is locked against rotation within the shielding sleeve. The invention further relates to a shielded holder comprising the last-mentioned locked reservoir and a shielding sleeve having a bottom portion with an internal cross-section which is triangular to dodecagonal or forms a segment of a circle.

Abstract: The invention relates to polyhydric phenol compounds of the general formula ##STR1## wherein R is a hydrogen atom or a saccharide moiety;A and B are hydrogen atoms or form together a C--C bond;R.sub.1 is a hydroxy group and R.sub.2 is a hydrogen atom, orR.sub.1 and R.sub.2 form together an oxygen atom;Z is a hydroxy group, an amino group, a carboxy group or a N-(carboxymethyl)carbamoyl group;X* is a radioactive halogen isotope; andm and n are 0 or 1, with the proviso, that m is 1 if n is 0, and that m is 0 if n is 1.The radiolabelled phenol compounds can be used for diagnosis and therapy.

Abstract: An aromatic compound (such as benzene) is alkylated with a alkene (such as propylene) by contacting the two compounds together in the presence of a tungsten on zirconia catalyst. The reaction preferably takes place at elevated temperature and elevated pressure. The process of the invention has very high selectivity and conversion, and produces no or only very low amounts of undesirable oligomers (as measured by bromine number).

Abstract: Hydrocarbons, gas mixtures of hydrocarbons, and the like containing hydrogen sulfide are brought into intimate contact with a hydrogen sulfide scavenger prepared by reacting an alkylenepolyamine with formaldehyde, whereby the amount of hydrogen sulfide in the hydrocarbon is significantly reduced.

Abstract: Hydrogen sulfide evolution in a heavy hydrocarbon (such as a residual fuel oil) derived from a heavy crude oil (such as a API 8 gravity crude) is suppressed by contacting the hydrocarbon with a compound corresponding to the reaction product of a heterocyclic aldehyde (such as furfural) and an organic primary amine.

Abstract: Bromobiphenyls (such as 2-fluoro-4-bromobiphenyl) are synthesized by reacting together a phenylboronic acid (such as phenylboronic acid) and a bromoiodobenzene (such as 2-fluoro-4-bromoiodobenzene). The reaction generally takes place with the aid of a catalyst (such as palladium in a zero valance state) and an inert solvent (such as fluorobenzene). Control of temperature is very important to obtain both an acceptable reaction rate and an acceptable level of terphenyl byproduct.
