Dosimetrie eines Blutbestrahlungsgerätes [PDF]

Strahlentherapie und Onkologie, 1998
Blood and blood products are irradiated to avoid the graft-versus-host disease (GVHD) in immunosuppressed patients and to destroy tumor cells during the intra-operative autotransfusion in tumor surgery. For that purpose more and more dedicated gamma irradiators are used.

Physiologically Based Pharmacokinetic Modeling to Predict Nicotine Pharmacokinetics of Nicotine Pouches Under Naturalistic Use Conditions

The Journal of Clinical Pharmacology, EarlyView.
Abstract Adult users of traditional tobacco products like combustible cigarettes (CC) or moist smokeless tobacco (MST) products can reduce exposure to toxicants by switching to potentially less harmful alternatives such as tobacco‐free nicotine pouches (NP). Nicotine exposure assessment is an important consideration to determine the switching potential

Optimising Radiation Dose Estimation: UNSCEAR DAP‐to‐ED Conversion in Uterine Artery Embolisation

Journal of Medical Radiation Sciences, EarlyView.
This study uses the conversion factors from the ‘UNSCEAR Global Survey on Medical Exposure: A User Manual’ to estimate radiation dose exposure for patients undergoing uterine artery embolisation. Estimating the effective dose provides interventional radiologists and interventional radiographers a better understanding of the stochastic risks associated ...
