The somatostatin receptors on rat pancreatic acinar membranes were demonstrated by use of a radioiodinated (125I-) analogue of somatostatin (SMS 204-090 or [Tyr3]SMS). The tracer was found to bind to the receptor with a Kd of 58 pM. The number of sites detected by this tracer (4.7 pmol/mg of protein) was 5-10 times higher than the number of sites previously found with other tracers. Since the l...
BACKGROUND Technetium-99m-hydrazinonicotinamide-Tyr3-octreotide (99mTc-HYNIC-TOC) is recognized as a promising radiopharmaceutical for diagnosing neuroendocrine tumors (NETs). However, 99mTc-HYNIC-TOC dosimetry has been investigated only for adults. As pediatric radionuclide therapies become increasingly common, similar dosimetric studies for children are urgently needed. The aim of this study ...
Using a 2,3-diamino pyrazine substrate and yttrium triflate catalyst, various 2-alkyl and aryl substituted 3,8-diaminoimidazo[1,2-a]pyrazines were efficiently prepared through Groebke-Blackburn-Bienaymé MCR. In particular, a novel 2-piperonyl 3,8-diaminoimidazo[1,2-a]pyrazine structure was prepared exclusively with this new method and was found to have moderate Hsp90 inhibitory activity. A crys...
This investigation consisted of two parts. In part one, a High Rate Physical Vapor Deposition Process was developed for the deposition of metals, alloys, compounds and dispersion strengthened alloys. The relationship between the deposition temperature, the microstructure and the mechanical properties was studied. The materials resulting from this process were shown to have oroperties very simil...
