introduction individual x-ray diffraction patterns of biological tissues are obtained via interference of coherent scattering with their electrons. many scientists have distinguished normal and cancerous breast tissue, bone density, and urinary stone types using the x-ray diffraction patterns resulting from coherent scattering. the goal of this study was to introduce an optimized method for obt...

Background: H2AX is a histone variant that is systematically found and ubiquitously distributed throughout the genome. DNA double-strand breaks (DSBs) induce phosphorylation of H2AX at serine 139 (γH2AX), an immunocytochemical assay with antibodies recognizing γH2AX has become the gold standard for the detection of DSBs. The importance of this assay to investigate different individu...

disseminated candidiasis is an opportunistic infection in immunosuppressed animals by candida species. the purposes of this study were to determine the predominant candidal forms in different tissues and tissue reactions. sixteen dogs were selected in this study. the treatment dogs were immunosuppressed by intravenous administration of cyclophosphamide and after 5 days, they were challenged wit...

conclusions alterations were present in both the aspect and spacing of collagen fibrils and in the shape of elastic fibers. the present familial combination of scad and edsh, with almost similar ultrastructural features suggests a possible connection between both conditions. case presentation we present a woman with scad and her five close relatives showing obvious or suggestive signs of edsh. ...

the reliability of gene expression profiling based technologies and methods to find transcriptional differences representative for the original samples is influenced by the quality of the extracted rna. hence, rna extraction is the first step to investigate the gene expression and its function. consequently, the quality of extracted rna is really significant. correspondingly, this research was ...

To calculate and evaluate wave scattering and penetration of electromagnetic waves in different biological tissues it is necessary to use a realistic model of the human body, with all tissues resolved and separately assigned with appropriate electric/magnetic properties. We report the development of a realistic 3D whole-body human model that has been adapted for simulation in CST software, cont...

Introduction: Staff and patient Movement in static magnetic field MRI scanner induces current density in the human tissues, so cause biologic effects in people. The aim of this study was the Modelling of current density induced by moving individual with different velocities in static magnetic field of magnetic resonance imaging. Materials and Methods: current ...

background marketing new radiography devices necessitates documenting their absorbed x-ray doses. since the current literature lacks studies on new devices, we assessed the doses of two new devices that had not previously been assessed. objectives the new devices were compared to the promax three dimensional (3d) scanner at two fields of view (fov) in nine critical head and neck tissues and org...
