The automatic exudate segmentation in colour retinal fundus images is an important task in computer aided diagnosis and screening systems for diabetic retinopathy. In this paper, we present a location-to-segmentation strategy for automatic exudate segmentation in colour retinal fundus images, which includes three stages: anatomic structure removal, exudate location and exudate segmentation. In ...

OBJECTIVES This study aimed to examine the peritoneal penetration of intravenous doripenem, a novel carbapenem used for the treatment of intra-abdominal infections. PATIENTS AND METHODS Doripenem (500 mg) was administered to 10 patients before abdominal surgery. Venous blood and peritoneal exudate samples were obtained at the end of infusion (0.5 h) and every hour for 6 h afterwards. The drug...

The aim of this study was to assess the efficacy and pharmacokinetic profiles of gentamicin, vancomycin, and levofloxacin in a rat air pouch model, in which Staphylococcus aureus (ATCC 25293) was used as the test organism. Antibiotic treatments (i.p.) were started 1 hour after bacterial inoculation and continued for 5 days. Bacterial counts and antibiotic concentrations were determined in pouch...

BACKGROUND Orthopaedic implant infections are treated by surgical debridement, systematic antibiotic treatment or local antibiotic treatment with antibiotic-loaded beads. Currently antibiotic concentrations in wound exudate, serum, urine or tissue samples are determined with HPLC or fluorescent spectrometric assays. Both methods are heavily influenced due to proteins in the samples. QUESTIONS...

Problems with exudate production occur if the wound becomes ‘stuck’ in the inflammatory stage and the production of exudate is overstimulated. Exudate found in chronic wounds (those that fail to heal after six weeks) has a different makeup to that in acute wounds and is often produced in higher quantities. Chronic wound exudate does not have the active growth factors found in acute wound exudat...
