Electron Microscopy [PDF]

open access: yes, 2012
Correlative light (LM) and transmission electron microscopic (TEM) analysis is useful, if ultrastructural details of cells need to be related to functional aspects which can only be examined at the LM level. The first protocol presented here introduces a relatively simple way of obtaining TEM images which, on the one hand, reveal ultrastructural ...

Outcome of hypofractionated breast irradiation and intraoperative electron boost in early breast cancer: A randomized non‐inferiority clinical trial

open access: yesCancer Reports, 2021
Background Intraoperative electron radiotherapy (IOERT) followed by hypofractionated whole breast irradiation (HWBI) provides the shortest possible time of adjuvant breast irradiation. The efficacy of either method has been described in previous reports;
