conclusions due to the significant reduction in the mean inactivation dose of colon cancer cells in the presence of gold nanoparticles, it seems that gnps are suitable options to achieve a new approach in order to improve radiotherapy efficiency without increasing the prescribed radiation dose. results cell survival in the presence of gnps was more than 90% and the maximum uptake of gnps was ob...

The study investigated the effect of various doses of carbendazim on the morphology of the magnum of the Japanese quail. No morphological changes were observed in the magnum in birds treated with carbendazim at doses of 25 mg/kg and 100 mg/kg bodyweight. A carbendazim dose of 400 mg/kg bodyweight was the lowest dose which caused morphological changes in the magnum. Histologically, carbendazim c...

3 PURPOSE: The aim of this study was to investigate how the diagnostic accuracy in digital mammography is affected by dose to the breast. MATERIAL AND METHODS: Structures resembling invasive tumours and microcalcifications on x-ray images were positioned in an anthropomorphic breast phantom equivalent to a 50 mm compressed breast containing 50% glandular tissue. The average glandular dose based...

In an experimental study in rats, cimetidine, a potent gastric-acid inhibitor (50 mg/kg, .p.o.) reduced the macromolecular glycoprotein level of glandular stomach. The administration of cimetidine at a dose of 50 mg/kg, which inhibited the gastric lesions induced by hypoxia (13% O2 for 6 hours), reduced the glandular stomach level of high molecular glycoproteins in animals receiving a low oxyge...

Our purpose in this study was to investigate the image quality and absorbed dose characteristics of a digital mammography imaging system with a CsI scintillator, and to identify an optimal x-ray tube voltage for imaging simulated masses in an average size breast with 50% glandularity. Images were taken of an ACR accreditation phantom using a LORAD digital mammography system with a Mo target and...

PurposeMammography is the diagnostic imaging practice used in screening to detect early lesions suspected of malignancy. It uses a low energy X-ray beam which dose order 2–3 mGy delivered patient breast cells. However, it has been speculated that could lead significant cell damage, when compared conventional X-ray. We investigated biological effects doses, with mean glandular doses (MGDs) 2.5 a...
