Multi‐fidelity Monte Carlo fusion for BNCT dose calculation using a dual‐branch network

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background Boron neutron capture therapy (BNCT) is a binary radiotherapy that selectively kills tumor cells. Its clinical implementation relies on Monte Carlo (MC)‐based treatment planning systems, which are time‐consuming and limit clinical workflow efficiency.

Image‐based evaluation of a commercial AI synthetic CT generator for brain and prostate MR‐only radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Synthetic CTs (sCT) were developed to provide electron density information for MR‐only treatment planning. Some AI‐based sCT generators have received FDA‐clearance and better capture tissue heterogeneity through voxel‐wise mappings to improve image guidance and dose calculation.

Initial experience of clinical implementation of an Online Simulation‐free CBCT‐based Adaptive Radiotherapy (OSCAR) workflow for palliative and urgent treatment indications

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background The current standard radiotherapy treatment planning workflow typically requires several hours to days, during which patients must wait before treatment can be initiated. In certain oncological situations, however, treatment should commence as soon as possible.

Emerging Function of Prolactin-Inducible Protein—Is This Important Tear Protein Found in Alzheimer’s Disease?

Cells
Alzheimer’s disease is characterized by a chronic, long-term neurodegenerative process and an increasing need for easily accessible biomarkers that enable early diagnosis and disease monitoring. For this reason, tears have attracted growing interest as a

Endoscopic dacryocystorhinostomy [PDF]

Vojnosanitetski Pregled, 2010
Background/Aim. Intensive epiphora (lacrimal apparatus disease) can make difficult daily routine and cause ocular refraction disturbances. In most cases ethiology is unknown, rarely occurs after nose surgical procedures, face fractures, in Wegener ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

The Anatomical Record, Volume 309, Issue 8, Page 1937-1969, August 2026.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

The Anatomical Record, Volume 309, Issue 8, Page 1995-2048, August 2026.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known
