FLASH Radiotherapy: Expectations, Challenges, and Current Knowledge

International Journal of Molecular Sciences
Major strides have been made in the development of FLASH radiotherapy (FLASH RT) in the last ten years, but there are still many obstacles to overcome for transfer to the clinic to become a reality. Although preclinical and first-in-human clinical evidence suggests that ultra-high dose rates (UHDRs) induce a sparing effect in normal tissue without ...

Evaluation of Experienced Manipulation Characteristics in Robotic Surgery Using Log Data From the Hinotori Surgical System

Annals of Gastroenterological Surgery, Volume 10, Issue 4, Page 1320-1330, July 2026.
This study analyzed log data from the Japanese hinotori surgical robot to characterize manipulation performed by experienced surgeons in robotic surgery. Compared with less‐experienced surgeons, the experienced group demonstrated shorter task durations, reduced travel distances with the right instrument (Arm3), faster and more dynamically modulated ...

Mex‐3 RNA‐binding family member A limits macrophage ferroptosis‐associated injury linked to the SLC7A11/GPX4 pathway in diabetic atherosclerosis

Clinical and Translational Medicine, Volume 16, Issue 7, July 2026.
Diabetes reduces macrophage MEX3A and aggravates atherosclerotic plaque instability. MEX3A stabilises Slc7a11 and Gpx4 mRNAs to sustain SLC7A11/GPX4 antioxidant defence. MEX3A deficiency promotes macrophage ferroptosis, lipid peroxidation and mitochondrial injury. Ferrostatin‐1 partially attenuates ferroptotic injury and diabetic plaque destabilisation.

Dietary Phytochemical Index and Its Relationship With Diminished Ovarian Reserve: Evidence From a Case–Control Study

Endocrinology, Diabetes &Metabolism, Volume 9, Issue 4, July 2026.
A higher dietary phytochemical index was associated with lower odds of diminished ovarian reserve, highlighting the potential role of phytochemical‐rich diets in supporting ovarian function and reproductive health. ABSTRACT Introduction Diminished ovarian reserve (DOR) represents a significant contributor to female infertility and adverse reproductive ...

Macro Monte Carlo dose calculation for very high energy electron (VHEE) radiotherapy

Medical Physics, Volume 53, Issue 7, July 2026.
Abstract Background Very high energy electron (VHEE) radiotherapy has gained growing interest owing to its potential to reach deep‐seated targets and induce FLASH effect. Dose calculations can be performed using analytical or Monte Carlo (MC) methods. Analytical approaches enable rapid dose computation but suffer from limited accuracy in heterogeneous ...

Possible mechanisms and simulation modeling of FLASH radiotherapy

FLASH radiotherapy (FLASH-RT) has great potential to improve patient outcomes. It delivers radiation doses at an ultra-high dose rate (UHDR: ≥ 40 Gy/s) in a single instant or a few pulses.
