Hematodinium is a parasitic dinoflagellate of numerous crustacean species, including the economically important Atlantic snow crab, Chionoecetes opilio. The parasite was isolated from C. opilio in the fall of 2010 and 2011 and cultured in vitro. Several media were tested, with Nephrops medium yieldi...

Measurement of systemic immunoglobulin (Ig) concentrations in horses and camelids is important for early and accurate diagnosis of immunodeficiencies in order to provide proper medical intervention. As a consequence, there is a demand for up-to-date, economic, rapid and precise diagnostic assays for...

As an alternative to blanket dry cow therapy (BDCT), selective dry cow therapy (SDCT) is considered a more judicious approach to antimicrobial use for the purpose of mastitis control during the non-lactating period. The purpose of this research was to evaluate the utility of a 3M Petrifilm-based on-...

Lepeophtheirus salmonis is a copepod parasite of salmonid fish, commonly referred to as sea lice, and is particularly pathogenic to Atlantic salmon (Salmo salar). Although endemic on wild salmon, L. salmonis infection intensity rarely reaches clinical disease levels in wild fish. The stationary natu...

One of the major limitations of the use of optoacoustics (OA) for the imaging of prostate cancer is the relatively low resolution when performed in real time. The work presented in this thesis aims to address this limitation by applying frequency-based analyses, which contribute additional informati...

The Pacific Island Countries including the Fiji Islands are heavily dependent on imported petroleum fuels for their energy needs. This is a major cause of environmental vulnerability as well as economic vulnerability due to high and volatile crude oil prices. A combination of Demand Side Management ...

Approximately 60% of human pathogens and emerging infectious diseases are zoonotic. Simulation models are increasingly being used to investigate the spread of diseases, evaluate intervention strategies and guide the decisions of policy makers. In this thesis a systematic review of modeling methods a...

Following stroke, impairments in arm function are common motor deficits in survivors, affecting thousands of people each year. A useful technique used in clinical rehabilitation of patients with arm impairments is to force use of the impaired arm through constraint of the unaffected (or less affecte...

Effective control of parasitic sea lice (including Lepeophtheirus salmonis and Caligus elongatus), is a major challenge currently facing sea cage salmon aquaculture. Emamectin benzoate (EMB; SLICE®), a macrocyclic lactone (ML), has been the drug of choice for sea lice treatment over the past decade...

The American lobster (Homarus americanus) is harvested along the eastern seaboard of North America and forms the economic backbone of many small fishing communities in Atlantic Canada and the northeastern United States. The industry sets minimum size (carapace length) for harvesting American lobster...

The field of fungal taxonomy has been enduring in recent years due to the progress and application of molecular tools used in concert with morphological analysis. The fungal kingdom is extremely diverse and estimated to include 1.5 million species. Only 11% of these fungi are currently described in ...

Schizophrenia is a devastating neurological disorder that affects approximately 1% of the population and is characterized by positive, negative, and/or cognitive symptoms. Positive symptoms are associated with increased glutamate (Glu) and/or dopamine (DA) signaling in the nucleus accumbens (NAcc) w...

Alcyonacean octocorals (Order Alcyonacea, amended from Order, Gorgoniidae) are both dominant on Caribbean reefs and prolific sources of bioactive natural products. Although extensive literature has been published with respect to stony coral-associated bacteria, very little is known regarding bacteri...

Mast cells are crucial effector cells in host defense and immunoregulation. They are equipped with an impressive array of receptor systems which allows them to rapidly respond to pathogen-associated signals. G protein-coupled receptors (GPCRs) mediate mast cell activation and mediator release in res...

Sturgeon are harvested worldwide for their meat and eggs, sold as caviar and are among the most economically important fish species worldwide. A generally low physiological response to external stimuli/stressors has been documented in these phylogenetically primitive species. Considering how little ...

BACKGROUND Myocardial fibrosis is a hallmark of hypertrophic cardiomyopathy (HCM). Human patients with HCM have high serum concentrations of biomarkers of collagen synthesis, indicating a profibrotic state. This abnormality exists in sarcomere mutation carriers both with and without overt left ventr...
