Background: One of the main problems of dedicated IORT accelerators is to determine dosimetric characteristics of the electron beams. Monte Carlo simulation of IORT accelerator head and produced beam will be useful to improve the accuracy of beam dosimetry.Materials and Methods: Liac accelerator head was modeled using the BEAMnrcMonte Carlo simulation system. Phase-space files were generated at...

Intracardiac flow of intravenously injected radiopaque material was studied by means of rapid simultaneous biplane stereoscopic angiocardiography. Intracardiac circulation times thus determined may be found useful in recognizing structural abnormality and in detecting changes in car(liac function. In mitral stenosis, a distinctive, but not specific, pattern was recognized whether or not mitral ...

Yeast strains have been widely used as models for eukaryotic microorganisms because of their amenability to biochemical and genetic studies. Recent advances of molecular biological techniques have made this organism an attractive host for functional expression of heterologous genes. Furthermore, structural genes corresponding to various genetic traits have been identified by complementation stu...

espite its heterogeneous clinical appearance, coeliac disease has a remarkable uniform human leuco-cyte antigen (HLA) association. The majority of coeliac disease patients carry a certain variant of HLA-DQ2, the rest carry HLA-DQ8. 1 2 As the physiological role of the HLA system is to present pep-tide fragments of antigens to T cells, it would seem logical that the HLA-DQ2 and HLA-DQ8 molecules...

Introduction: Intraoperative electron radiation therapy (IOERT) is one of the cancer treatment techniques that delivers high doses to tumor bed during surgery. IOERT can be performed by either conventional LINACs or dedicated IORT accelerators such as LIAC (Light Intraoperative Accelerator). Two types of applicators can be used with LIAC dedicated accelerator including conventi...
