Article Synopsis
- The study produced dressings using Ag/ZnO nanoparticles and lavender oil incorporated into a PVA/Pet matrix via electron beam irradiation.
- The nanoparticles were identified as spherical and about 27.4 nm in size, with the overall swelling capacity of the dressings improving significantly under certain conditions, but decreasing with higher irradiation doses.
- The dressings exhibited biocompatibility, antimicrobial properties, and effective wound healing in rat models, indicating potential for use in clinical wound management.
Article Synopsis
- - The study examines the biodistribution, metabolism, and radiation dosimetry of a new radiotracer, [F]FNM, which targets NMDA receptors and may help investigate neurological and psychiatric diseases using PET/CT imaging in rats.
- - Researchers evaluated the stability of [F]FNM in human plasma and performed PET/CT scans on rats to collect data on organ uptake and determine effective radiation doses for human models.
- - Results indicate [F]FNM is stable in plasma with a 53% free fraction and low metabolism, showing potential for safe use in humans due to its low total effective dose compared to other PET radiotracers.
Unlabelled: The objective of this study was to evaluate the value of direct examination and culture of gastric fluid in the treatment of early neonatal bacterial infections (INBP) in pre-term infants.
Materials And Methods: Observational study conducted over 6 months in a Type III center. All hospitalized premature babies who had routine gastric fluid sampling at birth during the period of the study were included.
Segmenting the retinal vessels from fundus images is a prerequisite for many CAD systems for the automatic detection of diabetic retinopathy lesions. So far, research efforts have concentrated mainly on the accurate localization of the large to medium diameter vessels. However, failure to detect the smallest vessels at the segmentation step can lead to false positive lesion detection counts in a subsequent lesion analysis stage.
