Previously we have identified and characterized three murine microbicidal proteins purified from the granule fraction of cells from the murine macrophage cell line RAW264.7. During these studies evidence was obtained for the presence of an additional antimicrobial protein in the cytosolic fraction of RAW264.7 cells that had been activated with interferon-gamma (IFN-gamma). In this study we have...

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 ...

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...

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.

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 ...

Individual cone snail ( Conus sp.) contains thousands of bioactive peptides, but there are limited studies on its antimicrobial peptides (AMPs). Here, we investigated AMPs along with AMP-derived genes in the representative Chinese tubular C. betulinus ) by integration our previously published multi-omics (genomics, transcriptomics, and peptidomics) data. We identified a total 466 putative from ...
