The Single, the Whole, and the Pooled: Implications of Tissue Choice for Stable Isotope Analysis

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT In the exciting era of non‐invasive tissue sampling and data reuse via open access databases, it is increasingly challenging to ensure comparability of sample types for stable isotope analysis in ecology. According to the theoretical predictions about the changes in the stable isotope values between prey and consumers and tissue turnover rates,

Mapping the Landscape of Over‐Scanning in CT Imaging: A Scoping Review

Journal of Medical Radiation Sciences, EarlyView.
Over‐scanning in CT is highly prevalent and contributes to unnecessary radiation exposure, with notable impact on radiosensitive organs. Standardised protocols and AI‐assisted planning show strong potential to optimise scan range and reduce excess dose.

Radiographers' Paediatric CT Radiation Dose Consideration: A Quantitative Study at Hospitals in Urban South Africa

Journal of Medical Radiation Sciences, EarlyView.
This descriptive quantitative survey and a cross‐sectional design present an investigation on paediatric radiation dose consideration by radiographers. Paediatric patients have a higher dose risk related to CT scan exposures. This study showed that there are gaps in specialised training and a need for stricter paediatric imaging protocols.

Methodological constraints for the stable isotope analysis of different tissues: A comparison between muscle and whole‐body samples in freshwater gammarids

Limnology and Oceanography: Methods, EarlyView.
Abstract Carbon (δ13C) and nitrogen (δ15N) stable isotope ratios allow the reconstruction of food webs, provided that all trophic levels are properly characterized. In freshwater ecosystems, small‐bodied invertebrates often occupy central positions in food webs, with whole‐body samples commonly used for their stable isotope analysis, due to ...

COVID‐19 Amplifies Sex‐Specific Dopamine and Glial Responses in a Parkinson's Disease Mouse Model

Movement Disorders, EarlyView.
Abstract Background Exposure to environmental agents, including viral infections, may increase Parkinson's disease (PD) susceptibility, especially in males, but the neurodegenerative risk extent of COVID‐19 remains uncertain. Objectives We investigated the plausible link between severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection and
