Poser
No full textPoser is a book of poems consisting of seven sections. The poems inside the book deal with a range of topics, but focus centrally around the development of identity in contemporary society. The work calls to question the paths human beings seek in order to affirm selfhood, and deals heavily with the psychological problem known as "Imposter Syndrome." The sections address distinct periods of development and their corresponding spiritual, social, and human inquiries, which end up defining the shapes of our lives.M.F.A.Includes bibliographical referencesby Evan Gill Smit
Natural mineral particles are cytotoxic to rainbow trout gill epithelial cells in vitro
Full text linkWorldwide increases in fluvial fine sediment are a threat to aquatic animal health. Fluvial fine sediment is always a mixture of particles whose mineralogical composition differs depending on the sediment source and catchment area geology.Nonetheless, whether particle impact in aquatic organisms differs between mineral species remains to be investigated. This study applied an in vitro approach to evaluate cytotoxicity and uptake of four common fluvial mineral particles (quartz, feldspar, mica, and kaolin; concentrations: 10, 50, 250 mg L21) in the rainbow trout epithelial gill cell line RTgill-W1. Cells were exposed for 24, 48, 72, and 96 h. Cytotoxicity assays for cell membrane integrity (propidium iodide assay), oxidative stress (H2DCF-DA assay), and metabolic activity (MTT assay) were applied. These assays were complemented with cellcounts and transmission electron microscopy. Regardless of mineral species, particles #2 mm in diameter were taken up by the cells, suggesting that particles of all mineral species came into contact and interacted with the cells. Not all particles, however, caused strong cytotoxicity: Among all assays the tectosilicates quartz and feldspar caused sporadic maximum changes of 0.8–1.2-fold compared to controls. In contrast, cytotoxicity of the clay particles was distinctly stronger and even differed between the two particle types: mica induced concentration-dependent increases in free radicals, with consistent1.6–1.8-fold-changes at the 250 mg L21 concentration, and a dilated endoplasmic reticulum. Kaolin caused concentrationdependent increases in cell membrane damage, with consistent 1.3–1.6-fold increases at the 250 mg L21 concentration. All effects occurred in the presence or absence of 10% fetal bovine serum. Cell numbers per se were marginally affected. Results indicate that (i.) natural mineral particles can be cytotoxic to gill epithelial cells, (ii.) their cytotoxic potential differs between mineral species, with clay particles being more cytotoxic, and (iii.) some clays might induce effects comparable to engineered nanoparticles

Nodular gill disease: a unique form of proliferative gill disease in rainbow trout, Salmo gairdneri Richardson
No full textIn an outbreak of proliferative gill disease in laboratory rainbow trout fingerlings lesions were multifocal among filaments and uniquely severe in the distal region of affected filaments, forming nodules. This contrasted with the more common forms of proliferative gill disease in Ontario, such as bacterial gill disease, in which lesions are diffuse along and among filaments. The cause is unknown, although cells with a very distinctive morphology were closely associated with the lesions..RE: 22 ref.; SC: ZA; CA; VE; 0V; 0ISource type: Electronic(1) http://upei-resolver.asin-risa.ca?sid=SP:CABI&id=pmid:&id=&issn=0140-7775&isbn=&volume=8&issue=6&spage=511&pages=511-522&date=1985&title=Journal%20of%20Fish%20Diseases&atitle=Nodular%20gill%20disease%3a%20a%20unique%20form%20of%20proliferative%20gill%20disease%20in%20rainbow%20trout%2c%20Salmo%20gairdneri%20Richardson.&aulast=Daoust&pid=%3Cauthor%3EDaoust%2c%20P%20Y%3bFerguson%2c%20H%20W%3C%2Fauthor%3E%3CAN%3E19862272504%3C%2FAN%3E%3CDT%3EJournal%20article%3C%2FDT%3
Cancer and exercise do mix
Full text linkFirst paragraph: When you hear the word “cancer” probably the last thing that you think of is physical activity. In fact, most of us think of cancer as a death sentence. Treatments for cancer make many people feel lousy and the side effects of treatment include fatigue, anxiety, nausea, vomiting and pain. So it is hardly surprising that people who are diagnosed with cancer are not reaching for their running shoes or gym kit.

Novel insights on microbiome dynamics during a gill disease outbreak in farmed rainbow trout (Oncorhynchus mykiss)
No full textThe generic term “Gill disease” refers to a wide range of disorders that affect the gills and severely impact salmonid aquaculture systems worldwide. In rainbow trout freshwater aquaculture, various etiological agents causing gill diseases have been described, particularly Flavobacterium and Amoeba species, but research studies suggest a more complex and multifactorial aetiology. Here, a cohort of rainbow trout affected by gill disease is monitored both through standard laboratory techniques and 16S rRNA Next-Generation Sequencing (NGS) analysis during a natural disease outbreak and subsequent antibiotic treatment with Oxytetracycline. NGS results show a clear clustering of the samples between pre- and post-treatment based on the microbial community of the gills. Interestingly, the three main pathogenic bacteria species in rainbow trout (Yersinia ruckeri, Flavobacterium psychrophilum, and Flavobacterium branchiophilum) appear to be weak descriptors of the diversity between pre-treatment and post-treatment groups. In this study, the dynamics of the gill microbiome during the outbreak and subsequent treatment are far more complex than previously reported in the literature, and environmental factors seem of the utmost importance in determining gill disease. These findings present a potential novel perspective on the diagnosis and management of gill diseases, showing the limitations of conventional laboratory methodologies in elucidating the complexity of this disease in rainbow trout. To the authors’ knowledge, this work is the first to describe the microbiome of rainbow trout gills during a natural outbreak and subsequent antibiotic treatment. The results of this study suggest that NGS can play a critical role in the analysis and comprehension of gill pathology. Using NGS in future research is highly recommended to gain deeper insights into such diseases correlating gill’s microbiome with other possible cofactors and establish strong prevention guidelines
