background and objective: concurrent chemoradiotherapy (ebrt + cisplatin) plus intracavitary brachytherapy is the standard of care in patients with advanced cervical cancer. however, some patients are unable to undergo brachytherapy due to massive residual tumor or anatomical distortion. in this study, we evaluated the treatment outcome in patients with locally advanced cervical cancer undergoi...

in this paper, a new algorithm for system identification based on frequency response is presented. in this method, given a set of magnitudes and phases of the system transfer function in a set of discrete frequencies, a system of linear equations is derived which has a unique and exact solution for the coefficients of the transfer function provided that the data is noise-free and the degrees of...

cutaneous hodgkin’s lymphoma is a rare disease (0.5% to 3.4%) which tends to be in the setting of an advanced disease and has a poor prognosis. treatment of patients with cutaneous involvement of hodgkin’s lymphoma is according to dissemination of disease (systemic or localized therapy). the majority of data in this context are based on individual case reports or literature reviews. we have rep...

objective to determine the role of ketogenic diet in the treatment of intractable epilepsy in children. materials & methods sixty six consecutive children (1-16 years old) with intractable epilepsy whose seizure were not neurodegenerative nor febrile in origin were recruited. they received the ketogenic diet and we evaluated its effect on seizure frequency for 3 months. all these children had m...

The self-assembly of molecularly precise nanostructures is widely expected to form the basis of future high-speed integrated circuits, but the technologies suitable for such circuits are not well understood. In this work, DNA self-assembly is used to create molecular logic circuits that can selectively identify specific biomolecules in solution by encoding the optical response of near-field cou...

The response of a free-standing graphene monolayer exposed to few tens femtoseconds long extreme ultraviolet (XUV) pulse was studied theoretically in order analyze and compare contributions various mechanisms the damage, understood here as global atomic disintegration. Our simulation results indicate that nonthermal disintegration structure is predominant damage mechanism for layer. Only at hig...

Treatment of bone metastases comprises over 10% of the workload of a radiation-oncology center. Bone metastases produce severe pain and immobility, necessitate narcotic use, and reduce the quality of life. A good palliative treatment must be complete, free from side effects and fast; Thus we decided to evaluate Strontium-89 (89Sr) effectivity for palliation of breast and prostate cancer b...

elevated amount of the free radicals due to ionizing radiation causes deteriorating damage on immune system. therefore, we made attempts to investigate the protective effect of vitamin e (vit-e), a biological antioxidant in balb/c mice, so as to find an affordable prophylactic supplementation for individuals who are at risk. several groups of mice were selected and exposed to sub-lethal g -irra...
