Application of the market-ready NAVETTA electrodeposition chamber for controlled exposure with nano-scaled aerosols.

Exposure of lung epithelia to aerosols is omnipresent. Chronic exposure to polluted air is a significant factor in the development of pulmonary diseases, which are among the top global causes of death, including COVID-19, chronic obstructive pulmonary disease, lung cancer, and tuberculosis. As efforts to prevent and treat lung diseases increase, the development of pulmonary drug delivery systems has become a major area of interest.

Effects of gold fiducial marker implantation on tumor control and toxicity in external beam radiotherapy of prostate cancer.

Background: Evidence regarding the effects of fiducials in image-guided radiotherapy (IGRT) for tumor control and acute and late toxicity is sparse.

Patients And Methods: Patients with primary low- and intermediate-risk prostate cancer, 40 with and 21 without gold fiducial markers (GFM), and treated between 2010 and 2015 were retrospectively included. The decision for or against GFM implantation took anaesthetic evaluation and patient choice into account.
