The in vitro alkaline comet assay with liver models as a complementary tool for genotoxicity assessment of N-nitrosaminesNARA Subscribed
N -nitrosamine (NA) impurities in pharmaceuticals represent “cohort of concern” compounds under ICH M7(R2), due to their mutagenic/carcinogenic potential, involving cytochrome P450 (CYP)-mediated metabolic activation. Increasing interest in mammalian cell-based genotoxicity/mutagenicity assays prompted our assessment of the in vitro alkaline comet assay regarding its predictive power for NAs. Here, precision-cut liver slices (...
Background Resilience in aging—the capacity to maintain cognition and function despite neuropathology—has been described through cognitive reserve, brain reserve, and maintenance. The dynamic Neurocognitive Adaptation (dNA) framework expands these constructs by defining resilience as a lifelong process of adaptive engagement across cognitive, physical, creative, and social domains that shape neural integrity and cognitive outc...
Sustainable agricultural development not only addresses global food insecurity but may also alleviate poverty by enriching the lives of millions of smallholder farmers. Improving the sustainability and profitability of agriculture where smallholders are dominant creates profound impacts because small landholding farmers produce approximately 70–80% of the global food. The need for a thorough understanding of the factors affect...
Resource modification by ecosystem engineers generates hotspots of stream community assembly and ecosystem functionNARA Subscribed
Ecosystem engineers can generate hotspots of ecological structure and function by facilitating the aggregation of both resources and consumers. However, nearly all examples of such engineered hotspots come from long‐lived foundation species, such as marine and freshwater mussels, intertidal cordgrasses, and alpine cushion plants, with less attention given to small‐bodied and short‐lived animals. Insects often have rapid life c...
183 Effects of prolonged hay net feeding on equine behaviorNARA Subscribed
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
Effective data management plays a key role in oceanographic research as cruise-based data, collected from different laboratories and expeditions, are commonly compiled to investigate regional to global oceanographic processes. Here we describe new and updated best practice data standards for discrete chemical oceanographic observations, specifically those dealing with column header abbreviations, quality control flags, missing...
Animals can be important in modulating ecosystem‐level nutrient cycling, although their importance varies greatly among species and ecosystems. Nutrient cycling rates of individual animals represent valuable data for testing the predictions of important frameworks such as the Metabolic Theory of Ecology ( MTE ) and ecological stoichiometry ( ES ). They also represent an important set of functional traits that may reflect both...
