Assessing the Predictive Value of the SAMe-TT2R2 Score for Poor Anticoagulation Control in a Diverse Ethnic Population.

In Asian countries, warfarin is still widely used for stroke prevention in non-valvular atrial fibrillation compared to non-vitamin K antagonist oral anticoagulants (NOACs) due to its affordability. A tool such as the SAMe-TTR is needed to determine the probability of achieving and maintaining good anticoagulation control with warfarin therapy. However, it requires validation in the Malaysian cohort.

Monte Carlo-based Investigation of Absorbed-dose Energy Dependence of Thermoluminescent Dosimeters in Therapeutic Proton and Carbon Ion Beams.

Background: The present study is aimed at calculating relative absorbed-dose energy response correction () of commonly used thermoluminescent dosimeters (TLDs) such as LiF, LiBO, and AlO as a function of depth in water for protons (50-250 MeV/n) and carbon ion (80-480 MeV/n) beams using Monte Carlo-based FLUKA code.

Materials And Methods: On-axis depth-dose profiles in water are calculated for protons (50-250 MeV/n) and carbon ion (80-480 MeV/n) beams using FLUKA code. For the calculation of , selective depths are chosen based on the depth-dose profiles.

Monte Carlo-based dosimetry of proposed bi-radionuclide (I and Ru/Rh) eye plaque: A feasibility study.

Background: Combining the sharp dose fall off feature of beta-emitting Ru/Rh radionuclide with larger penetration depth feature of photon-emittingI radionuclide in a bi-radionuclide plaque, prescribed dose to the tumor apex can be delivered while maintaining the tumor dose uniformity and sparing the organs at risk. The potential advantages of bi-radionuclide plaque could be of interest in context of ocular brachytherapy.

Purpose: The aim of the study is to evaluate the dosimetric advantages of a proposed bi-radionuclide plaque for two different designs, consisting of indigenous I seeds and Ru/Rh plaque, using Monte Carlo technique.

Radiation-induced DNA damage by proton, helium and carbon ions in human fibroblast cell: Geant4-DNA and MCDS-based study.

. Radiation-induced DNA damages such as Single Strand Break (SSB), Double Strand Break (DSB) and Complex DSB (cDSB) are critical aspects of radiobiology with implications in radiotherapy and radiation protection applications..

Evaluation of uncertainty in personal dose measured using CaSO4:Dy-based TLD badge at different workplaces.

The metrological quality of a measurement is characterised by evaluating the uncertainty in the measurement. In this paper, uncertainty in personal dose measured using individual monitoring CaSO4:Dy-based thermoluminescence dosimeter badge is evaluated by application of the guide to the expression of uncertainty in measurement method. The present dose reporting quantity, whole body dose (WBD) and the proposed quantity, personal dose equivalent, Hp(10) has been used as measurands.
