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

Microplastics and the Endocrine–Metabolic Interface: Novel Diagnostic Tools Targeting Thyroid–Adipose Axis

Environmental Toxicology, EarlyView.
ABSTRACT Microplastics (MPs) have been identified as major environmental contaminants that can affect organisms directly and act as carriers of particles and chemical additives, thereby aggravating endocrine networks that coordinate metabolic homeostasis.

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Solid-state dosimeters have rendered ionization chambers obsolete for routine diagnostic X-ray quality control. [PDF]

J Appl Clin Med Phys
ABSTRACT Today's diagnostic medical physicist finds a broad variety of instruments available to make the numerous quality control (QC) measurements needed for routine equipment evaluations. One of the distinguishing features of different options is the availability of multi‐purpose solid‐state detectors (SSD) and application‐specific ion chambers (IC ...

Integrating Chemical, Electrical, and Photonic Effects Into a Unified ETOP‐Based Plasma Dose Framework

High Voltage, EarlyView.
ABSTRACT In plasma medicine and biological applications, plasmas typically deliver a complex combination of reactive chemical species and multiple physical energy components. However, establishing a unified and comparable dose metric to characterise their integrated biological effects remains a major challenge that continues to limit progress in this ...

Effect of oxygen and nanoparticles on human skin and colon cells exposed to synchrotron‐based X‐ray FLASH beams

Journal of Synchrotron Radiation, EarlyView.
Most cancer patients will be treated by radiotherapy, and recent findings suggest that delivering radiation at `FLASH' ultra‐high dose rates reduces damage to healthy tissues while still damaging the tumour. This project experimentally validates the reduced healthy tissue damage of FLASH radiotherapy on cells using synchrotron‐based beams, which will ...
