Post‐Therapeutic Dosimetry of Metastatic Castration‐Resistant Prostate Cancer With 177Lu‐PSMA: Experiences From Two University‐Based Hospitals in Thailand

Asia-Pacific Journal of Clinical Oncology, EarlyView.
ABSTRACT Objective 177Lu‐PSMA radioligand therapy (RLT) is increasingly used to treat metastatic castration‐resistant prostate cancer (mCRPC). Posttreatment dosimetry is essential for assessing normal organ absorbed doses. Therefore, this study aims to evaluate normal organs dosimetry in mCRPC patients undergoing 177Lu‐PSMA‐RLT from two university ...

Occupational exposure to metal welding and cataract: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Background Metal welding generates ultraviolet radiation (UVR) of cataractogenic wavelengths, and UVR emitted during welding has been associated with cataract formation, but results from prior studies are conflicting. Methods We conducted a systematic review and meta‐analysis of epidemiological studies addressing associations between ...

No evidence of the long-term in vitro toxicity of Aeroxide P25 TiO2 nanoparticles in three mammalian cell lines despite the initial reduction of cellular mitochondrial activity

Nukleonika
We studied the effects of Aeroxide P25 titanium dioxide nanoparticles (TiO2 NPs) with a diameter of 21 nm on induction of DNA damage and long-term survival of three human cell lines: hepatocellular liver carcinoma HepG2, colorectal adenocarcinoma HT29 ...

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Small dose monitor based on silicon-carbide diodes for FLASH radiotherapy. [PDF]

Med Phys
Abstract Background The FLASH biological effect in radiotherapy has been observed to appear at ultra‐high dose rates UHDR (>$>$40 Gy/s), where the accurate dosimetry at such high rates is still a challenge. Purpose A new 4 ×$\times$ 4 array of SiC‐based detectors (1 mm diameter, 2.2 mm pitch) is proposed for dosimetry in UHDR, as well as the ...

Plaque-adaptive flexible film dosimetry system for Ru-106 plaque brachytherapy commissioning and quality assurance. [PDF]

Med Phys
Abstract Background Ruthenium‐106 (Ru‐106) plaque brachytherapy is an established treatment modality for choroidal melanoma that delivers localized beta radiation while sparing surrounding ocular structures. It is widely used in Europe and parts of Asia, whereas COMS Iodine‐125 and Palladium‐103 plaques remain the standard in the United States. However,

The Sparing Effect of Multibeam Ultra‐High Dose‐Rate Irradiation on Intestinal Tissue in Mice

Cancer Science, EarlyView.
This study demonstrates that UHDR retains its robust sparing effects on intestinal toxicity under multibeam conditions with a split dose thresholds at 2.2–4 Gy. These findings suggest that multibeam irradiation can be employed in abdominal and pelvic UHDR to achieve good dose conformity.
