Background: The reactivation of international travel in 2021 has created a new scenario in which the profile of the traveler to medium-high health risk areas may well have changed. However, few studies have analyzed this new profile since the reopening of borders in that year.

Methods: We designed an ad hoc questionnaire that was administered face-to-face by our medical team during appointments with 330 travelers in the second half of 2021.

Is coulomb explosion a damaging mechanism for (125)IUdR?

Int J Radiat Biol

April 2005

Department for Safety and Radiation Protection, Forschungszentrum Jülich GmbH, D-52425 Jülich, Germany.

Purpose: To test the integrity of the thymine molecule that experiences an increasing number of charges due to the loss of Auger electrons emitted by the decay of incorporated 125I. Besides the radiation action of these electrons, Coulomb explosion is suspected to be an additional mechanism responsible for the strong radiotoxic effect of decaying DNA-incorporated 125I. The two-step decay process initiates a first Auger cascade within 10(-16) to 10(-14) s resulting in the release of about 7 electrons on average and a corresponding large positive charge on the 125Te daughter atom.

We describe our preliminary studies on the development of methods to measure hypoxia in standard paraffin sections of human tumors. Three parameters were investigated. First, image analysis of tumor vascularity yielded the parameter diffusion limited fraction (DLF), which is the amount of tumor tissue greater than a fixed distance from the nearest blood vessel.
