Although plasma pTau181 has been shown to accurately discriminate patients with Alzheimer’s disease from healthy older adults, there are few studies of plasma biomarkers among middle-aged populations. Given the potential utility of plasma AD biomarkers such as pTau181 in screening for disease risk, examining pTau181 in a middle-aged cohort without AD is important for future implementation. The objectives of this study were to...
Global Fire Emissions Linked to Madden-Julian OscillationNARA Subscribed
Understanding the relationship between fire activity and climate variability is a major concern for the scientific community and is essential for reducing economic losses and life-threatening fire hazards. However, the drivers of fire activity and the influence of climate variability remain uncertain. Here, we show that the Madden-Julian Oscillation (MJO)—a dominant tropical subseasonal variability—influences fire activity by...
Sand tiger shark Carcharias taurus mating season in the northwest Atlantic Ocean inferred from wound healing dynamicsNARA Subscribed
All sharks and rays reproduce using internal fertilization. This necessitates males and females to be coupled tightly during copulation, and as a result, bite wounds associated with mating occur. The appearance of these bite wounds can be used to gauge the timeframe of mating activity without direct observation of copulation. A wound staging system was developed for the sand tiger shark Carcharias taurus through longitudinal o...
The Toxicology Investigators Consortium 2023 Annual ReportNARA Subscribed
Background: The decrease in the production of Argopecten purpuratus scallops in Chile is linked to extensive larval deaths in hatcheries caused by bacterial pathogens, particularly Vibrio genus, threatening sustainability. Traditional antibiotic practices raise concerns, urging research on eco-friendly strategies like bacterial probiotics. This study explores the metabolic responses of scallop larvae to Vibrio bivalvicida and...
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...
Mapping the Green-Lipped Mussel (Perna canaliculus) Microbiome: A Multi-Tissue Analysis of Bacterial and Fungal DiversityNARA Subscribed
Poor health and mortality events of the commercially important and endemic New Zealand green-lipped mussel ( Perna canaliculus ) pose a threat to its industry. Despite the known importance of microbiomes to animal health and environmental resilience, the host-associated microbiome is unexplored in this species. We conducted the first baseline characterization of bacteria and fungi within key host tissues (gills, haemolymph, di...
Salmonids are the third major farmed finfish species after carps and tilapines, and thus contribute to global food fish production. However, as the aquaculture industry continues to grow, several challenges have emerged. Left unchecked, current problems will hinder aquaculture development. Metabolomics is one of the powerful biotechnological tools that will contribute to solving some of the pressing problems. This review aims...
