Feasibility study of the positronium imaging with the J-PET tomograph [PDF]
, 2018 A detection system of the conventional PET tomograph is set-up to record data from e+ e- annihilation into two photons with energy of 511 keV, and it gives information on the density distribution of a radiopharmaceutical in the body of the object. In this paper we explore the possibility of performing the three gamma photons imaging based on ortho ...

TP53‐Mutated Myeloid Neoplasms: 2024 Update on Diagnosis, Risk‐Stratification, and Management
American Journal of Hematology, EarlyView.ABSTRACT Alterations in the tumor suppressor gene TP53 are common in human cancers and are associated with an aggressive nature. Approximately 8%–12% of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) harbor TP53 mutations (TP53mut) and present immense challenges due to inherent chemoresistance and poor outcomes.

Flux crystal growth of Ba2[(UO2)2Ti2O8]: Structures, spectroscopies and implications
Journal of the American Ceramic Society, Volume 106, Issue 2, Page 1381-1390, February 2023., 2023 We report a flux crystal growth of Ba2[(UO2)2Ti2O8], and subsequent structural and spectroscopic studies using multiple techniques including synchrotron single crystal X‐ray diffraction and X‐ray absorption near‐edge structure spectroscopy. In addition, its vibrational modes and thermal stability were investigated.

Letter: Radiopharmaceuticals in breastfeeding [PDF]
Australian Prescriber, 2016 In the article on drugs in breastfeeding,1 I was dismayed at the inclusion of ‘radiopharmaceuticals’ in the table of drugs contraindicated in breastfeeding. There was little elaboration within the article as to the reason for this. The other drugs listed have sufficient evidence of the potential for serious adverse effects to the infant.

Premenopausal bilateral oophorectomy and Alzheimer's disease imaging biomarkers later in life
Alzheimer's &Dementia, EarlyView.Abstract INTRODUCTION Premenopausal bilateral oophorectomy (PBO) before the age of 46 years is associated with an increased risk of dementia. We investigated the long‐term effects of PBO performed before age 50 years on amyloid beta (Aβ), tau, and neurodegeneration imaging biomarkers of Alzheimer's disease (AD).
