Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Assessment of Thyroid Uptake Ratio Values in a Normal Population. Establishment of Normal Reference Values for 99mTc‐Pertechnetate Thyroid Uptake in an Australian Population

open access: yesJournal of Medical Radiation Sciences, EarlyView.
An Australian first, this study examined normal reference ranges for 99mTc‐pertechnetate thyroid uptake. Through a retrospective and prospective analysis, this study found a new reference range of 0.4%–2.4%. The findings suggest that locally derived reference values may differ from historical data and highlight the importance of region‐specific ...

More than just anemia: Uncovering celiac disease beneath the surface: A case report

open access: yesJPGN Reports, EarlyView.
Abstract Celiac disease (CD) is an immune‐mediated disorder triggered by gluten in genetically susceptible individuals. Although iron deficiency anemia is a common presentation, other micronutrient deficiencies may occur. We describe a 3.5‐year‐old female whose initial presentation of CD was severe, asymptomatic normocytic anemia secondary to copper ...
