In Vivo Dosimetry Evaluation of External Photon Treatments of Brain, Pelvis and Breast Cancer with Diode Dosimeters

Basic & Clinical Cancer Research, 2016
Background: Delivering the maximum dose to tumor while achieving the minimum dose delivery to normal tissue; is the most important goal in external radiotherapy. Diode in vivo dosimetry is widely considered to be an important tool for quality improvement

Combining flat‐panel imaging with internal BB markers for precise HDR brachytherapy source localization: A simulation study

Medical Physics, Volume 53, Issue 2, February 2026.
Abstract Background High Dose Rate (HDR) brachytherapy delivers concentrated radiation to the tumor by placing a high‐dose‐rate radioactive source directly inside the target. However, the sharp dose falloff also increases susceptibility to errors and uncertainties.

New alternatives in photoprotection: Preparation and evaluation of lamellar silicate derivatives and their use as sunscreens

International Journal of Cosmetic Science, Volume 48, Issue 1, Page 172-185, February 2026.
The use of nanotechnology in sunscreens has increased, with various filters and organoclays tested for new intercalated formulations. As animal toxicity tests decrease, New Approach Methodologies are favoured. The S4 + OMC‐NC improved cell survival under SSL and showed antimutagenic properties, making it a promising candidate for safe photoprotection ...

Tooth–bone attachment tissue is produced by cells with a mixture of odontoblastic and osteoblastic features in reptiles

Journal of Anatomy, Volume 248, Issue 2, Page 251-268, February 2026.
Tooth attachment in vertebrates ranges from ligament‐based anchorage in mammals to direct fusion in many reptiles. In the veiled chameleon, we identified a transient cell population—termed ankyloblasts—at the tooth‐bone interface. These cells exhibit both odontoblast‐ and osteoblast‐like features.

In vivo dosimetry and acute toxicity in breast cancer patients undergoing intraoperative radiotherapy as boost

Radiation Oncology Journal, 2017
Purpose To report the results of a correlation analysis of skin dose assessed by in vivo dosimetry and the incidence of acute toxicity. This is a phase 2 trial evaluating the feasibility of intraoperative radiotherapy (IORT) as a boost for breast cancer ...

Quality assurance during interstitial brachytherapy: in vivo dosimetry using MOSFET dosimeters

Journal of Contemporary Brachytherapy, 2018
Purpose Brachytherapy procedure may result in acute tissue reactions like edema, causing deviations between planned and measured doses. The rationale for in vivo dosimetry in interstitial brachytherapy is to assess the accuracy of the delivered dose in ...
