introduction: ubiquicidin 29-41 (ubi) is a fragment of the cationic antimicrobial peptide that is present in various species including humans. the purpose of this study was to investigate radiochemical and biological characteristics of [6-hydrazinopyridine-3-carboxylic acid (hynic)]-ubi 29-41 designed for the labeling with 99mtc using tricine as coligand. methods: synthesis was preformed on a ...

In recent years the physiological role of the proinsulin C-peptide has received increasing attention, focusing on the potential therapeutic value of C-peptide replacement in preventing and ameliorating type 1 diabetic complications. In order to consolidate these new data and to identify the immediate directions of C-peptide research and its clinical usefulness, an International Symposium was he...

  Introduction: It has been shown that some primary human tumors and their metastases, including prostate and breast tumors, over-express gastrin-releasing peptide (GRP) receptors. Bombesin is a neuropeptide with a high affinity for these GRP receptors. The purpose of this study was to prepare and evaluate the characteristics of a new Freeze-dried kit, [6-hydrazinopyr...
