Introduction Systemic inflammation and endothelial dysfunction are potentially modifiable factors implicated in Alzheimer’s disease (AD), which offer potential therapeutic targets to slow disease progression. Methods We investigated the relationship between baseline circulating levels of inflammatory (TNF-α, IL-1ß) and endothelial cell markers (VCAM-1, ICAM-1, E-selectin) and 18-month cognitive decline (ADAS-cog12) in 266 mild...
Marine mammals are exposed to increasing intensities of anthropogenic stressors such as acoustic disturbance and contaminants. Correlative studies have suggested concerning shifts in behavioral and physiological status of stress-exposed individuals, which could alter the health and survival of marine mammal populations. However, functional studies of the effects of multiple stressors on marine mammals are lacking. To fill in t...
We compared the electrosensory system of two benthic elasmobranchs Hemiscyllium ocellatum and Chiloscyllium punctatum . The distribution of the ampullary pores on the head was similar for both species, with a higher density of pores anteriorly and a lower density posteriorly, although C. punctatum generally possessed larger pores. Ampullary canals of the mandibular cluster were quasi‐sinusoidal in H. ocellatum , a shape previo...
Aim Large tropical trees form the interface between ground and airborne observations, offering a unique opportunity to capture forest properties remotely and to investigate their variations on broad scales. However, despite rapid development of metrics to characterize the forest canopy from remotely sensed data, a gap remains between aerial and field inventories. To close this gap, we propose a new pan‐tropical model to predic...
Experimental induction of mouthrot in Atlantic salmon smolts using Tenacibaculum maritimum from Western CanadaNARA Subscribed
Mouthrot, or bacterial stomatitis, is a disease which mainly affects farmed Atlantic salmon, ( Salmo salar , L.), smolts recently transferred into salt water in both British Columbia (BC), Canada, and Washington State, USA. It is a significant fish welfare issue which results in economic losses due to mortality and antibiotic treatments. The associated pathogen is Tenacibaculum maritimum , a bacterium which causes significant...
Morphological comparison of the ampullae of Lorenzini of three sympatric benthic raysNARA Subscribed
This study investigated and compared the morphology of the electrosensory system of three species of benthic rays . Neotrygon trigonoides , Hemitrygon fluviorum and Maculabatis toshi inhabit similar habitats within Moreton Bay, Queensland, Australia. Like all elasmobranchs, they possess the ability to detect weak electrical fields using their ampullae of Lorenzini. Macroscopically, the ampullary organs of all three species are...

An eDNA assay for Irish Petromyzon marinus and Salmo trutta and field validation in running waterNARA Subscribed
This pilot study presents an environmental DNA ( eDNA ) assay for sea lamprey Petromyzon marinus and brown trout Salmo trutta , two species of economic and conservation importance in the Republic of Ireland. The results demonstrate the effectiveness of eDNA for assessing presence of low‐abundance taxa (here, P. marinus ) for environmental managers, and they highlight the potential for assessing relative abundance of rare or in...
