Background: CT is a diagnostic imaging modality giving higher patient dose in comparison with other radiological procedures, so the calculation of organ dose in CT exams is very important. While methods to calculate the effective dose have been established (ICRP 26 and ICRP 60), they depend heavily on the ability to estimate the dose to radiosensitive organs from the CT procedure. However, dete...

in this study, we investigate the immunostimulatory effects of alcoholic extract of the coffee seed on cell-mediated immune response andcyclophosphamide-induced (cp) immunosuppressed mice. the assessment of cellular immune function was carried out by the measurement of delayed-type hypersensitivity (dth) response. according to the literature survey, cyclophosphamide has only suppressing effect ...

Extensive research on the nutritional and medical application of selenium nanoparticles (SeNPs) was performed in past decades. Besides nutritional values, new characteristics such as antibacterial and anticancer properties depict a bright future for high Selenium (Se) consumption in the coming years. Se is essential for the proper functioning of most of the m...
