New developed cylindrical TM010 mode EPR cavity for X-band in vivo tooth dosimetry. [PDF]

PLoS ONE, 2014
EPR tooth in vivo dosimetry is an attractive approach for initial triage after unexpected nuclear events. An X-band cylindrical TM010 mode resonant cavity was developed for in vivo tooth dosimetry and used in EPR applications for the first time.

177Lu‐labeled amidoxime‐functionalized biodegradable microspheres for transarterial radioembolization of hepatocellular carcinoma

Precision Radiation Oncology, EarlyView.
Scheme 1. Schematic illustration of the synthesis and therapeutic evaluation of PLA‐g‐PAO microspheres (PLA‐g‐PAO‐Ms). Monodisperse PLA microspheres (PLA‐Ms) were initially fabricated via microfluidic technology. Surface grafting of acrylonitrile monomers was subsequently achieved through radiation‐induced graft polymerization, followed by ...

Baicalein Sensitizes Radioresistant BT549 and MCF7‐R Breast Cancer Cells by Modulating Rac1 Signaling

Phytotherapy Research, EarlyView.
ABSTRACT Radioresistance remains a key barrier in breast cancer (BC) treatment. Baicalein, a flavonoid from Scutellaria baicalensis, has shown potential to enhance radiosensitivity. This study investigates its efficacy and mechanism in radioresistant BC models. Radioresistant BC cell models were established via fractionated irradiation and validated by

Context‐Dependent Radioenhancement by Platinum Nanoparticles Under Conventional and Ultra‐High Dose‐Rate “FLASH” Radiotherapy

Small, EarlyView.
Overview of the experimental workflow and main findings of the study investigating Pt‐NPs‐mediated radioenhancement under conventional 134 dose‐rate (CONV) and ultrahigh dose‐rate (UHDR) 9 MeV electron irradiation. Pt‐NP distribution and uptake were characterized in 4T1 spheroids and syngeneic tumor models.

Harnessing the nonthermal effects of ultrasound for cancer treatment: From mechanisms to applications

Smart Molecules, EarlyView.
Nonthermal ultrasound transforms acoustic energy into diverse therapeutic bioeffects through cavitation, mechanical stimulation, and physicochemical activation. This review discusses how acoustic parameters, biological mechanisms, and responsive materials interact to influence nonthermal ultrasound‐enabled cancer therapies. Mechanism‐guided engineering
