background: chromosomal alterations play an important role in carcinogenesis. enhanced chromosomal radiosensitivity is shown for many cancer predisposition conditions including breast cancer. in this study chromosomal radiosensitivity and the frequency of background sister chromnatid exchanges (sce) in lymphocytes of normal individuals and breast cancer patients was compared. materials and meth...

A common feature of financial time series is their strong persistence. However, long memory may just be the spurious effect of the presence of one or more structural breaks. There exist four testing procedures to evaluate this issue. All tests are constructed under the null of true long memory versus the alternative of spurious long memory induced by a structural break. We consider the " Tempor...

objective: the passage of ionizing radiation in living cells creates clusters of damaged nucleotides in dna. in this study, dna strand breaks induced by the beta particle of iodine-131 (i-131), have been determined experimentally and compared to monte carlo simulation results as a theoretical method of determining131i damage. materials and methods: in this experimental study, in order to create...
