Ecologisch profiel van de Strandgaper (Mya arenaria)
No full text(See below for English summary. Content of rapport is in Dutch) De Strandgaper (Mya arenaria) is een in de ondiepe kustwateren van Nederland algemeen tweekleppig schelpdier dat tot 40 cm diep ingegraven in de bodem leeft. Vooral op de bij laag water droog vallende platen in het Waddenzeegebied en in Ooster- en Westerschelde is het een belangrijke soort. In de ondiepe kustzone is de soort aanzienlijk minder talrijk. De soort voedt zich met partikeltjes van uiteenlopende aard (vooral flagellaten en detritus) die uit het water worden gefiltreerd. De Strandgaper is in het project Watersysteemverkenningen (WSV) gekozen als doelvariabele om de milieukwaliteit van de Nederlandse zoute wateren te toetsen. In het Ecoprofiel komt naar voren dat het voorkomen van de Strandgaper negatief beïnvloed wordt door diverse verontreinigingen en het storten van baggerspecie. Organische microverontreinigingen kunnen het ontstaan van tumorcellen induceren. Het geringe voorkomen van de Strandgaper in het oostelijk deel van de Westerschelde moet in verband worden gebracht met daar voorkomende concentraties microverontreinigingen. Storten van baggerspecie heeft pas dan negatief effect op lokaal aanwezige Strandgapers als meer dan 8 cm slib wordt afgezet. -English- The soft shell clam (Mya arenaria) is a common bivalve mollusc in shallow Dutch coastal waters. It lives in the sediment at depths down to 40 cm. It is especially abundant at intertidal flats in the Wadden Sea, Ems estuary, Westerschelde and Oosterschelde. In coastal waters the species is far less abundant. The species is a suspension feeder utilising various particles, such as phytoplankton and detritus, from the water column. In the 'Aquatic Outlook' project Mya arenaria has been chosen as a sentinel organism for measuring environmental quality of coastal waters. The occurrence of Mya arenaria can be negatively influenced by various pollutants as well as by dumping of dredged material. Organic micropollutants are considered as a cause of prevalence of tumor cells in these animals. The low numbers of Mya arenaria that are present in the eastern part of the Westerschelde are related to the concentrations of micropollutants in that part of the estuary. Dumping of dredged material will affect local populations of this species only if more than 8 cm of mud is deposited.Watersysteemverkenningen (WSV) 199

Changes induced by two strains of Vibrio splendidus in haemocyte subpopulations of Mya arenaria, detected by flow cytometry with LysoTracker
No full textFlow-cytometric characterisation of bivalve haemocytes is usually performed by light-scatter profiles based on size and complexity of the cells. Additional means of characterisation such as specific fluorescent dyes are not commonly used to discriminate cell subpopulations in challenged and unchallenged haemocytes. In the present study, we characterise the changes in haemocyte subpopulations of soft-shell clam Mya arenaria induced by in vivo challenge with 2 strains of Vibrio splendidus by using a fluorescent probe. Responses were measured 24 h after infection with either a local wild strain (7SHRW) or a modification (LGP32-GFP) of a strain associated with oyster mortalities in France (LGP32). Changes in haemocyte subpopulations were analysed using flow cytometry based on 2-parameter scatter profiles and lysosomal content reflected by LysoTracker staining. Forward and side-scatter profiles revealed 2 haemocyte subpopulations: hyalinocytes and granulocytes. Granulocytes exhibited significantly higher levels of lysosomal staining (p<0.01). Following infection with LGP32-GFP, both subpopulations merged into a single continuous group and their lysosomal content significantly decreased (p<0.05). Independent modifications after infection were observed in the proportions of subpopulations established by their lysosomal content. While the subpopulation of hyalinocytes had lower levels of lysosomal content after infection, especially with LGP32-GFP (p<0.001), the subpopulation of granulocytes had similar levels of lysosomes after infection with 7SHRW and significantly decreased levels after infection with LGP32-GFP (p=0.001). Our data suggest specific modulation of bivalve responses against pathogenic bacteria that would include degranulation.Accession Number: 20093356818. Publication Type: Journal Article.

Differential gene expression of γ-actin, Toll-like receptor 2 (TLR-2) and interleukin-1 receptor-associated kinase 4 (IRAK-4) in Mya arenaria haemocytes induced by in vivo infections with two Vibrio splendidus strains
No full textImmune function gene expression in Mya arenaria haemocytes was evaluated following in vivo infection with Vibrio splendidus LGP32-GFP and 7SHRW. Elongation factor 1α (EF-1α) with 2 (EF-2), after challenge with LGP32-GFP, and EF-1α with the ribosomal protein S-18, after challenge with 7SHRW, were found to be the most stable housekeeping genes. Using these internal controls and comparing the regulation induced by both strains, up-regulation of γ-actin, down-regulation of TLR-2 and up-regulation of IRAK-4 was significantly higher after challenge with LGP32-GFP (p<0.001, p=0.001 and p<0.05, respectively). These results suggest specific responses at a molecular level modulated by the bacterial strains. LGP32-GFP induced marked responses which coincide with a similar trend previously found on phenotypic responses under our experimental model

Perceived Credibility in News Depending on Author Race & Statistical Evidence
No full textThis 2x2 between-subjects experiment investigated the impact of the race of the reporter and statistical evidence upon perceived credibility. This study was run at a small midwestern university with 65 participants (60% female and 40% male) that had an average age of 19.26 years. These participants were asked to read a news article in an online format, answer a few short-answer questions over the content of the article, take a quick survey, answer a set of multiple choice questions about the content, and complete a demographic survey. The survey that the participants completed was adapted from a credibility scale utilized by Gaziano and McGrath (1986) and measured credibility on a five-point likert scale. It has been hypothesized that articles with more statistical evidence present will lead to higher ratings of credibility in relation to the report and a white male author will lead to higher ratings of credibility in relation to the article. Finally, an interaction was also hypothesized between the race of the author and the statistical evidence present in the article such that when there is a presence of statistical evidence, the credibility ratings of the black and white male authors will not show a statistical difference. Whereas, without the presence of statistical evidence, the black male author will lead to significantly lower ratings in credibility in comparison to the white male author. A 2x2 between-subjects ANOVA indicated no significant results (p \u3e .05) suggesting that neither race or statistical evidence has a significant impact upon credibility
The Biological Effects of Trauma
No full textIn this paper, we sought to understand the effects of trauma through a biological lens so that we could better learn how all the different expressions of mental unwellness, as a result of trauma, affect our everyday lives. Previous research has predicted that the symptomatic consequences of trauma can be identified and affected by variables such as platelet serotonin concentrations, substance addiction, and cortisol levels. For our correlational study, we tested the strength of these relationships by examining naturalistic daily changes in their variables over a one-week period. We measured substance addiction by how many alcoholic drinks were consumed each day, inferred cortisol levels by levels of water retention of the wrist each day, serotonin concentrations by rating tiredness each day using a subjective scale, and inferred traumatic symptoms by heart rate each day. Data pooled across participants in our correlational study showed that alcohol intake, but not serotonin or cortisol levels, was significantly correlated with our physiological measurement of trauma levels. Though a minute finding, this information may be able to offer guidance and aid to future psychologists and healthcare providers in both the furthering of their research and in the betterment of treatment plans for those who have undergone trauma. These findings could also motivate councillors and therapists to inaugurate more resources for combatting addiction into their practices.Supervising Instructor & Course Number: Michael Pollock, Psyc 215 (“Biological Psychology”
Growing Mya-1 T Cells for Adoptive Immunotherapy
No full textabstract: CD4+CD25+ FOXP3+ cells are recognized as the most reliable regulatory T cell subset. However, the intracellular nature of the FOXP3 transcription factor limits its use for the isolation or selection of viable regulatory T cells for adoptive immunotherapy. Nuclear localization of FOXP3 has been more strongly associated with induced regulatory T cell (Treg) function than increased expression of FOXP3 alone. Several different cell culture methods and T cell activation techniques can induce increased expression of FOXP3 in a variety of T cell models, but Rapamycin (an mTOR inhibitor) was recently shown to differentially induce nuclear localization of FOXP3 when compared with IL-10 and TGFβ. Feline Tregs have been well characterized and share many of the phenotypic and functional characteristics of murine and human Tregs. We cultured feline Mya-1 T cells in conditions that would differentially promote effector or regulatory phenotypes and correlated nuclear localization of FOXP3 with other quantitative morphologic features using imaging flow cytometry. We compared the morphologic features of cells with high intra-nuclear concentrations of FOXP3 cultured without IL-2, with IL-2, and with IL-2 and Rapamycin before and after non-specific antigenic stimulation with Concanavalin-A. This analysis may help identify a population of pure regulatory T cells that would be more likely to maintain regulatory function following in-vitro expansion and activation. Furthermore, the feline T cell model could help elucidate important differences between murine and human Treg cells that would further translational efforts in adoptive immunotherapy. Now, we ask if nuclear localization of FOXP3 could be used to identify other morphologic differences between activated effector and regulatory T cells using a feline T cell line
