Previous studies have shown that some dysregulated miRNAs are involved in radioresistance of tumor cells. Here, we identified significantly decreased miR-424 expression in radioresistant cervical cancer cells and specimens from cervical cancer patients with radioresistance compared to their radiosensitive parental cells and specimens from radiosensitive patients, respectively. Ectopic expressio...

This study investigated 94.4% of Palestinian radio technologists and the mean percentage of correct answers for knowledge and awareness questions was 26.4%. The percentage of correct answers for questions testing knowledge of the ALARA (As Low As Reasonably Achievable) principle and hormesis hypothesis was 66.5% and 17.2%, respectively. Radio technologists with education level higher than bache...

Subpopulations that are genetically predisposed to radiation-induced cancer could have significant public health consequences. Individuals homozygous for null mutations at the ataxia telangiectasia gene are indeed highly radiosensitive, but their numbers are very small. Ataxia Telangiectasia heterozygotes (1-2% of the population) have been associated with somewhat increased radiosensitivity for...

Purified vaccinia virus was irradiated by 7-rays under direct-effect conditions. The ability of the irradiated samples to form plaques (infectivity) and to induce viral DNA synthesis was determined. The radiosensitive volume of the viral unit causing infection (I.9 × IO-X7 cm2) is very small compared with the volume of the whole viral DNA ( ~ IO %). The inactivation of the DNA replication funct...

Intracranial deposits of extramedullary hematopoiesis are extremely rare, and limited experience with the treatment of these lesions has been reported. Our review of the literature provides further insights regarding the clinical, radiological, and pathological behavior of these lesions and examines the available treatment strategies. Radiation therapy has proven to be an effective modality for...
