Homarus americanus has a life history that is similar to other arthropods, including a pelagic larval phase and a benthic adult phase. The larval phase is divided into three morphologically distinct stages, followed by metamorphosis to the post-larval phase. H. americanus larval development has been...

We review studies claiming that fish feel pain and find deficiencies in the methods used for pain identification, particularly for distinguishing unconscious detection of injurious stimuli (nociception) from conscious pain. Results were also frequently misinterpreted and not replicable, so claims th...

Sturgeon aquaculture has increased considerably worldwide but little is known about their immunological development and competence in early life stages. Culture of larvae is one of the most critical stages in intensive sturgeon farming, often associated with high mortality rates. The objective of th...

A variety of human enteropathogens, including viruses, bacteria, and parasites, have been shown to bioaccumulate in suspension-feeding bivalve shellfish. Cryptosporidium parvum is a zoonotic protozoan parasite that has been detected in many shellfish species within both fecally contaminated and clea...

Edaravone, an electron spin trapper with radical scavenging activity, has been shown to be effective in reducing infarct volume in humans following ischemic stroke. However, concerns of edaravone-induced renal toxicity have limited its clinical adoption. Previous work has demonstrated that edaravone...

Allergic diseases are a major medical concern with increasing prevalence in the world. Inflammation is one of the hallmarks of allergic diseases. Long chain n-3 polyunsaturated fatty acids (PUFAs) have been shown to inhibit allergic inflammation, but their direct effect on activation of the mast cel...

The present study demonstrates the benefits of combinatorial antioxidant therapy in the treatment of ischemic stroke. Male Sprague-Dawley rats were anaesthetised and the middle cerebral artery (MCA) was occluded for 30 minutes followed by 5.5 hours of reperfusion. Pretreatment with resveratrol 30 mi...

Discovery of novel bioactive metabolites from marine bacteria is becoming increasingly challenging, and the development of novel approaches to improve the efficiency of early steps in the microbial drug discovery process is therefore of interest. For example, current protocols for the taxonomic dere...

In this article, we compare quantitatively the efficiency of three different protocols commonly used in commercial defibrillators. These are based on monophasic and both symmetric and asymmetric biphasic shocks. A numerical one-dimensional model of cardiac tissue using the bidomain formulation is us...

The prevalence of Giardia duodenalis, Cryptosporidium spp. and other intestinal parasites was determined in dogs <1 year old from Prince Edward Island, Canada. Fecal samples were collected from the local animal shelter (n=62), private veterinary clinics (n=78) and a pet store (n=69). Intestinal para...

The adult American lobster (Homarus americanus) is susceptible to few naturally occurring pathogens, and no viral pathogen is known to exist. Despite this, relatively little is known about the H. americanus immune system and nothing is known about its potential viral immune response. Hundreds of rur...

This is the first transcriptomic study focusing on immunity in the commercially valuable American lobster (Homarus americanus). We have conducted an in vivo infection trial using the Gram-positive bacterium Aerococcus viridans var. homari to determine how H. americanus responds to this naturally occ...

Agricultural pesticide runoff has been suspected as the cause of numerous fish kills in rivers throughout Prince Edward Island but the impact on the surrounding marine environment is unknown. Endosulfan, an organochlorine pesticide, is a potent neurotoxin and molt inhibitor used to combat the Colora...

The present application relates to novel apocynin-lopioc acid covalent conjugates, compositions comprising these compounds and their use, in particular for the treatment of diseases, disorders or conditions that are mediated by oxidative stress. In particular, the present application includes compou...

A small commercial hunt for 5-7 weeks old grey seals (Halichoerus grypus) occurs intermittently around the Canadian Maritime provinces and may expand in the near future. We sought to better understand and, where possible, improve the harvesting methods of this hunt. We compared the use of the regula...

The zoonotic protozoan parasites Cryptosporidium parvum, and Giardia duodenalis can colonize the gastrointestinal tracts of many farmed, domestic and wild animals, and are capable of causing disease in humans. Due to their high prevalence in dairy and beef cattle, farms are considered to be potentia...

There are currently four invasive tunicate species which are causing significant challenges to the aquaculture industry in Atlantic Canada: Ciona intestinalis, Styela clava, Botryllus schlosseri and Botrylloides violaceus. Molecular PCR based assays have been developed in previous studies as high th...

Parasitic sea lice are a major challenge for salmon aquaculture. This is especially due to recent development of resistance to emamectin benzoate (EMB) in the parasite. We investigated 1) whether EMB treatment success in Grand Manan, Bay of Fundy, NB, can be explained through EMB bioassay and P-gp ...

Due to the challenges of managing invasive species, new technologies to assist in monitoring for the early detection of early life stages of invasive species is critical for many regions of the world. Invasive tunicates have been causing challenges to the shellfish aquaculture industry in Atlantic C...
