Article Synopsis
- The HyperSight high-performance CBCT imaging system provides better Hounsfield unit accuracy and image quality for treatment planning in cancer patients.
- A study compared dose calculation accuracy between HyperSight CBCT and traditional planning CT in prostate and lung cancer cases, evaluating various dose distribution parameters.
- Results showed HyperSight CBCT yielded accurate dose calculations for prostate patients, but breathing motion significantly affected accuracy for lung cancer patients.*
Article Synopsis
- Researchers used advanced momentum microscopy to investigate the electronic properties of the topological Dirac semimetal 1T-ZrTe, specifically focusing on the behavior of its Dirac cone above the Fermi level.
- They discovered the role of different scattering processes in how electrons relax, observing important electron-hole interactions and finding that the electrons' lifetime correlates linearly with their excess energy.
- The study offers new insights into the excited state dynamics of 1T-ZrTe, contributing to the understanding of ultrafast electron behaviors in 3D topological materials.
Background: Decellularized extracellular matrix (dECM) has been proposed as a useful source of biomimetic materials for regenerative medicine due to its biological properties that regulate cell behaviors. The present study aimed to investigate the influence of decellularized ECM derived from dental pulp stem cells (DPSCs) on gingival fibroblast (GF) cell behaviors. Cells were isolated from dental pulp and gingival tissues.

The aim of this study was to determine the added value of HyperSight CBCT imaging compared to conventional CBCT imaging in terms of organ visibility in the male pelvic region.
Materials And Methods: Twenty prostate cancer patients were included in this prospective clinical study.
