Purpose: The aim of this study was to relate lesion detectability to image contrast and noise for fi ve diff erent PET scanners, by performing an observer study of thorax phantom images. Methods: A thorax phantom containing four fi llable spheres with diameters of 10, 13, 17 and 23 mm in the mediastinal region, as well as cold lung, liver and spine inserts, was fi lled with 20 MBq F. The activi...

Background: Sperm cryopreservation has been associated with over production of reactive oxygen species (ROS). Buffalo spermatozoa are susceptible to ROS inducing damages due to insufficient level of cytoplsmic antioxidant along with high amount of poly unsaturated fatty acids composition in membrane structure. Therefore, appropriate antioxidant in buffalo cryopreservation extender would reduce ...

BACKGROUND Video-assisted thoracoscopic surgery (VATS) pulmonary wedge resection has emerged as the standard treatment for primary spontaneous pneumothorax. Recently, single-port VATS has been introduced and is now widely performed. This study aimed to evaluate the outcomes of the Tower crane technique as novel technique using a 15-mm trocar and anchoring suture in primary spontaneous pneumotho...
