BACKGROUND Edge stenosis remains a serious limitation of catheter-based vascular brachytherapy (VBT). This study aims to identify the mechanisms and evaluate strategies to minimize edge restenosis in patients treated with VBT. METHODS AND RESULTS Thirty-four porcine stented coronary arteries were irradiated (doses of 15 or 22 Gy) with (192)Ir trains of either 6 seeds (23 mm) with 0 mm coverag...
Flash is a specified function in TomoDirect that enables beam expansion by opening additional leaves to the target. This study assessed the theoretical dose distribution resulting from Flash in breast irradiation using TomoDirect. A cylindrical phantom that enabled dose distribution of the breast was used for verifying the effect of planning target volume (PTV) contouring and Flash. A total of ...
background: compressive neuropathy of median nerve is relatively common but development of an hourglass like constriction is a rare phenomenon. the purpose of this study is to show morphologic changes of median nerve in advances carpal tunnel syndrome. methods: eighty patients with thenar atrophy, anesthesia and paresthesia of first, second and third finger and severe changes of emg‑ncv were ch...
Combined QM/MM calculations of an activesite of Cytochrome P450cam have been performed, before and after a binding process of Cytochrome P450cam to Putidaredoxin. The calculations have been carried out for two coordination spheres of the heme active-site of Cytochrome P450cam, namely a 5-coordinated, and a 6coordinated system of this protein having a water molecule as a 6th ligand. An experimen...
