in this study, production, quality control and biodistribution studies of 166ho-zoledronate have been presented as a possible bone marrow ablative agent. ho-166 chloride was produced by thermal neutron irradiation of natural 165ho(no3)3 samples. 166ho-zoledronate complex was prepared by adding the desired amount of zoledronate solution (0.2 ml, 150 mg/ml in 1 m naoh) to appropriate amount of th...

various radiometal complexes have been developed for tumor imaging, especially ga-68 tracer. in the present study, the development of a radiogallium bis-thiosemicarbazone complex has been reported. [67ga] acetylacetonate bis(thiosemicarbazone) complex ([67ga] aats) was prepared starting [67ga]gallium acetate and freshly prepared acetylacetonate bis (thiosemicarbazone) (aats) in 30 min at 90°c. ...

We now know that approximately 30,000 to 40,000 genes effectively control and regulate the human body. The recent completion of a rough draft of the human genome and the complete sequence of Drosophila melanogaster, Caenorhabditis elegans, Mycobacterium tuberculosis, and numerous other sequencing projects provide a vast amount of genomic data for further refinement and analysis.1 These landmark...

bamboo-structured carbon nanotubes are grown on co-mo/mcm-41 catalyst in the temperature range of 873-973 k by thermal chemical vapor deposition of acetylene. this study shows that the purified carbon nanotubes have open tips and the metals of the catalyst are not encapsulated. thus, the bamboo-structure seems to grow from the base. pore size distribution of the product is quite narrow and is i...
