introduction: appendicitis is one of the most common surgical emergencies. in spite of the relatively high rate of negative appendectomy, as a result of miss diagnosis, uncertainty of diagnosis still continues to challenge physicians. the objective of this prospective study was to investigate the role of 99mtc-ubiquicidin (ubi) scintigraphy in the diagnosis of acute appendicitis and to compare ...

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 ...

Ubiquicidin 29-41 (UBI 29-41) is an antimicrobial peptide with six positively charged residues which preferentially binds to the negatively charged groups present on the microbial membrane by electrostatic interaction at the foci of infection. For this reason UBI 29-41 has been suggested to label by 99m Tc ( 99m Tc-UBI 2941)directly or by using coligand reagents like 6-hydrazinopyridine 3-carbo...

Background: UBI 29-41 (a derivative of antimicrobial peptide ubiquicidin) labelled with 99mTc is reported to discriminate between bacterial infections and sterile inflammatory processes. In this study, three lyophilized kit were performed, one of them based on the direct labelling with only SnCl2 as reducing agent , and other two based on 6- hydrazinopyridine-3-carboxylic acid (HYNIC) and trici...

A 31-year-old woman who had multiple orthopedic surgeries on the left lower limb and recently suffered from pain redness in lateral thigh was referred to hospital rule out osteomyelitis by [ 99m Tc]UBI scintigraphy. Except soft tissue inflammation mentioned region, scan showed significant diffuse both lungs uptake incidentally. The patient experienced symptoms of COVID-19 disease recently. Ches...
