To establish to what extent immune privilege interferes with T cell-mediated antitumor immun...
Background and purpose: Concave eye applicators of Ru-106, a beta emitter source, have a lot of use in brachytherapy of intraocular tumors. This has led to the need of knowing the exact dose distribution caused by beta radiation to the tumor and its normal surrounding tissue. The purpose of this study was the 3D calculation of dose distribution for three Ru-106 plaques: CCA, CCB, and CGD in a h...
The pivotal role of p53 in the regulation a vast array cellular functions has been subject extensive research. biological activity is not strictly limited to cell cycle arrest but also includes homeostasis, DNA repair, apoptosis, and senescence. Thus, mutations gene with loss function represent one major mechanisms for cancer development. As expected, due its key role, expressed throughout huma...
The occurrence of clinically symptomatic intraocular metastases as an initial manifestation of primary neoplasm is rare event. The recognition of metastatic ocular tumors is important since they indicate a poor prognosis. Prompt diagnosis and treatment can significantly improve the quality of life for these patients. We report the case of a 48-year-old man presenting with a two-week history of ...
