Developmental dynamics of ovine lung in health and cystic fibrosis at single-cell resolutionNARA Subscribed
The sheep lung has long been used to model aspects of the human lung, both its normal development and pathological changes that occur in ovine models of lung disease. The similarities between the two species provide an opportunity to investigate phases of lung development that are not accessible for investigation in humans, for example later in gestation. Here we use single cell (sc) RNA-seq to investigate the developmental dy...
An experimental approach to assess the combined effects of multiple stressors on a large vertebrate speciesNARA Subscribed
The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure. The population of bottlenose dolphins in Barataria Bay, Louisiana, experienced long...
Diet of juvenile skipjack herring Alosa chrysochloris : Ontogenetic shifts, predator–prey size ratios and mouth gape allometryNARA Subscribed
The skipjack herring Alosa chrysochloris inhabits Gulf of Mexico drainages, primarily the Mississippi River Basin, and estuarine environments in the Gulf of Mexico. The trophic ecology of the skipjack herring is poorly understood, therefore we quantified the length, mouth gape and gut contents of juvenile skipjack herring from the Mississippi River (fish n = 6), Illinois River (fish n = 181) and Ohio River (fish n = 255) and t...
Global patterns and regional insights into kelp forest protection, restoration, and stewardshipNARA Subscribed
Kelp forests are among the most extensive and productive coastal ecosystems, yet they remain underrepresented in global conservation policy despite widespread declines driven by interacting global- (i.e., ocean warming, marine heatwaves) to local-scale stressors. At the same time, kelp conservation and restoration efforts are expanding rapidly across regions, but measures of success and syntheses tend to primarily focus on eco...
Precision measurement of the Ds*+-Ds+ meson mass differenceNARA Subscribed
Abalone in the genus Haliotis are economically important for aquaculture. Abalone naturally graze on macroalgae; however, they are increasingly fed formulated pellets that lack essential nutrients in aquaculture. Dietary supplements may increase abalone growth performance, immunity, survival, and market traits. Despite these advantages, there has been limited industry uptake, which can be influenced by a lack of formal evidenc...
Purpose The DANFLU-1 trial suggested lower incidence of hospitalizations for pneumonia and influenza, respiratory disease and all-cause mortality among older adults receiving high-dose (HD-IV) versus standard-dose (SD-IV) influenza vaccine. This study assessed the relative effectiveness of HD-IV versus SD-IV according to comorbidity in elderly individuals. Methods This was a post-hoc analysis of the DANFLU-1 randomized control...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
Current opinion in biomass-based applications in per- and polyfluoroalkyl substances removal in water and soil systemsNARA Subscribed
Per- and polyfluoroalkyl substances (PFAS) represent a diverse class of persistent organic pollutants that are ubiquitously detected across water and soil environments, posing serious ecological and human health risks. PFAS compositions vary by environmental matrices. Long-chain compounds dominate groundwater, short-chain forms are common in stormwater, mixed PFAS appear in surface waters, and landfill leachates show the highe...
Alzheimer’s disease (AD) disproportionately affects women and carriers of the apolipoprotein E ε4 allele (APOE4), yet little is known about how sex and APOE interact to influence white matter (WM) integrity during disease progression. We integrated diffusion MRI and matched blood transcriptomic data to investigate these interactions and their underlying biological mechanisms. WM microstructure was quantified using diffusion te...
