introduction: ubiquicidin (ubi) 29-41 is a synthetic antimicrobial peptide that binds with the microbial cell membrane at the location of infection. this study was conducted to evaluate its probable efficacy as an infection-imaging agent with potential to differentiate bacterial infection from sterile inflammation in humans. methods: fifteen diabetic foot patients (10 males and 5 females) with...

ubiquicidin (ubi) [29-41] is a synthetic cationic antimicrobial peptide that preferentially binds to bacterial cell membrane at the site of infection. we aimed to assess diagnostic value of 99mtc-ubi [29-41] as a radiopharmaceutical in differentiation of bacterial infection from sterile inflammation in suspected orthopedic implants. nine patients suspected for orthopedic implant infection, all ...

We present a case of infective endocarditis (IE) diagnosed by the increased (99m)Tc-UBI specific uptake in the tricuspid valve region. In conclusion, our case data may indicate a first pass-like distribution with strong avidity of the tracer to infective endocarditis, facilitating image interpretation.

BACKGROUND The rice receptor kinase XA21 confers robust resistance to the bacterial pathogen Xanthomonas oryzaepv. oryzae(Xoo). We previously reported that XA21 is cleaved in transgenic plants overexpressing XA21 with a GFP tag (Ubi-XA21-GFP) and that the released C-terminal domain is localized to the nucleus. XA21 carries a predicted nuclear localization sequence (NLS) that directs the C-termi...

UNLABELLED Ubiquicidin (UBI) 29-41 is a cationic, synthetic antimicrobial peptide fragment that binds preferentially with the anionic microbial cell membrane at the site of infection. The current study was conducted to evaluate its potential as an infection-imaging agent in humans. METHODS Eighteen patients, 9 female and 9 male (mean age, 31.7 y; range, 5-75 y), with suspected bone, soft-tiss...

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-hydrazinopyridine3-carboxylic acid (HYNIC)]-UBI 29-41 designed for the labeling with Tc using tricine as coligand. Methods: Synthesis was preformed on a solid...

Bacterial infections are a major complication in human healthcare. Bacteria tracing and targeted delivery of antibiotics to bacterial infection sites being developed reduce the high mortality caused by pathogenic infections. Owing challenges accurate diagnosis infection, particularly identification biomaterial‐related bacteria, use bacteria‐targeting nanomaterials has become increasingly import...
