abstractbackground: delivering the radiation dose to the target volume and minimizing the dose to normal tissues are the main objectives in radiotherapy. the aim of our study is to enhance the contrast of the portal image to increase the accuracy of delineation of the organs in the irradiation field.   methods: the software was written based on local enhancement of the pixel values in image mat...

Prompt clinical diagnosis and timely treatment are the hallmarks of the proper care of diabetic patients with foot infections. The importance of careful clinical foot examination cannot be overemphasized. When infection is suspected, effort should be made to search for deeper infections, especially osteomyelitis. Numerous imaging techniques are available, but their cost-effectiveness has not be...

Bioimaging contributes significantly to our understanding of plant virus infections. In the present review, we describe technical advances that enable imaging of the infection process at previously unobtainable levels. We highlight how such new advances in subcellular imaging are contributing to a detailed dissection of all stages of the viral infection process. Specifically, we focus on: (i) t...

The main propose of this approach is to evaluate the efficiency of Tc-Ciprofloxacin (Infecton) imaging to detect infection sites induced in foot’s rat by staphylococcus aureus susceptible to ciprofloxacin in comparison with S aureus resistant to drug. S aureus bacteria have been isolated from the patients admitted in Imam Khomeini hospital Ahvaz Khuzestan Iran. According to the table of Clinica...

Influenza transmission efficiency in ferrets is vital for risk-assessment studies. However, the inability to monitor viral infection and transmission dynamics in real time only provides a glimpse into transmissibility. Here we exploit a replication-competent influenza reporter virus to investigate dynamics of infection/transmission in ferrets. Bioluminescent imaging of ferrets infected with A/C...

this is a report of a case with unilateral cavernous sinus thrombosis due to ipsilateral ethmoid sinusitis. a 10 year old female was admitted in our hospital with severe headache, purulent postnasal discharge, right eye proptosis and third cranial nerve palsy in the same eye. she had history of viral upper respiratory tract infection and then acute otitis media which did not improve with routin...

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...

one hundred sixty two domestic fowls were examined for toxoplasma infection by both indirect haemagglutination tests for toxoplasma antibodies and inoculation of their brains intraperitoneally into mice for the parasite. the overall sero-positive rate (spr) was 29 percent with the titers ranging from 1:20 to 1:6400. the number of each species tested and their spr were: 74 hens (27.0%), 35 roost...
