Antimicrobial Effects of Compounds Used in Cleaning Wipes

The antimicrobial effectiveness and level of biofilm inhibition of three compounds from Rockline Industries were tested, along with five compounds made by the St. Norbert College Organic Chemistry Department. The Rockline compounds, ColaLipid (CL), Sodium Benzoate (NaB) and Benzoic Acid (BA), were solubilized in 10% DMSO and tested at concentrations of 0.15%, 0.10%, and 0.01%. To ensure that any growth effects were due to the compounds in question, DMSO was also tested for antimicrobial activity. The compounds were tested against safe relative of eight bacteria of clinical importance (Acinetobacter baylyi, Bacillus subtilis, Escherichia coli, Enterococcus raffinosus, Enterobacter aerogenes, Pseudomonas fluorescens, Pseudomonas putida, Staphylococcus epidermidis) and one species of fungus (Candida albicans). The antimicrobial properties of these compounds were measured by reading absorbance at 600 nm of overnight cultures. Biofilm formation inhibition was measured using a crystal violet biofilm assay. ColaLipid and Benzoic Acid were found to inhibit growth of the bacterial and fungal strains, while Sodium Benzoate did not. Of the compounds synthesized by in St. Norbert organic chemists, two showed consistent inhibition of growth and three did not. ColaLipid, Benzoic Acid, and one organic compound showed consistent inhibition of biofilm formation.https://digitalcommons.snc.edu/collaborative_presentations/1081/thumbnail.jp

Exploring how age influences sensory perception, thirst and hunger during the consumption of oral nutritional supplements using the check-all-that-apply methodology

The Check-all-that-apply (CATA) method has been widely used for the sensory characterisation of many different foods and beverages. However, this methodology has been rarely used with older adults. The aim of this study was to measure the effectiveness of the CATA methodology to investigate the differences in sensory perception of Oral Nutritional Supplements (ONS) between younger and community dwelling older adults over successive sips of a full volume of two ONS. The study also sought to measure the effects of ONS on thirst, hunger and fullness. 160 participants (eighty aged over 65 and eighty aged 18-35) evaluated two ONS over two different days. They consumed five 40 ml aliquots of ONS amounting to one serving. After each 40 ml they completed a CATA questionnaire, which recorded liking using a 9-point hedonic scale and hunger, fullness, desire, and thirst using 100 mm visual analogue scales. The results indicated significantly lower levels in hunger (p ≤ 0.01) and thirst (p ≤ 0.01) in the older cohort than the younger cohort. Significant differences in texture perception with age were also observed with the younger cohort selecting ‘Watery’ significantly more (p ≤ 0.05) than the older cohort for ONS 1 and ‘Thick’ and ‘Viscous’ significantly more (p ≤ 0.05) for ONS 2. The study showed that the CATA methodology is appropriate for use with older adults. The findings enhanced our understanding of how an older population experience ONS and drivers of ‘liking’. This information has the potential to enhance ONS adherence and ultimately improve the nutritional status of older people

Other-Focus Versus Self-Focus: The Power Of Self-Transcendent TV Shows

Recently, a group of media scholars proposed that eudaimonic entertainment experiences can be differentiated into inward-driven and outward-driven experiences. The current study empirically tested this proposition by focusing on transcendent portrayals (i.e., content or character portrayals that focus on something greater than oneself) as one content characteristic to differentiate the proposed inward/self-focused from more outward/other-focused effects within the context of eudaimonic TV shows. A preregistered experiment (N = 147) revealed that highly transcendent TV shows elicited more self-transcendent emotions, universalism, and money donation behavior, as well as fewer self-image goals, than less transcendent TV shows. As expected, there was no difference between conditions in mixed affect (all but one of the TV shows), contemplation, and intrinsic need satisfaction. The results indicate that outward-oriented narratives include entertainment experiences previously associated with inward-oriented narratives, but not necessarily vice versa. The role of types of transcendent portrayals, quality of portrayals, and number of portrayals for the differentiation of various eudaimonic entertainment experiences are discussed.

Confronting Environmental Inequality: Assessing and Mitigating Students\u27 Exposure to Near Roadway Air Pollution in Silicon Valley

Near roadway vehicle emissions, such as particulate matter (PM), nitrous oxides, and other contaminants, are major sources of air pollution, which can cause respiratory and cardiovascular illnesses.1 Chronic air and noise pollution exposures can also negatively influence cognitive function and student learning. Of greatest concern are concentrations within 500 feet of high traffic street edges, but concentrations can be harmful at distances up to 1320 ft.2 Vulnerable populations such as children, the elderly, or those with impaired health are likely to suffer the greatest impacts. In 2003, the California legislature passed SB 352, prohibiting building new schools within 500 ft of high traffic roadways. However, SB 352 does not address what action should be taken to reduce the health risks for children at school sites already near high traffic roadways, and the Bill acknowledges that a disproportionate amount of low income students attend such schools. A recent report found that nationwide more than 8000 public schools or about one in every 11 public schools, serving roughly 4.4 million students is located within 500 ft. of a road with more than 30,000 vehicles per day, or at least 10,000 cars and 500 trucks per day. Many more head start and private schools are also exposed.3 An earlier study, found that 13.5% of students attended schools within 820 ft of a major roadway, concluding that minority and underprivileged children were disproportionately affected, although some results varied regionally.4 To better understand pollution patterns, environmental justice issues, and the community responses in Santa Clara County (SCC), we started field research in the Greater Washington Neighborhood of San Jose, CA. We started here because of the proximity of schools to high traffic roadways, and the support that Thriving Neighbors Initiative offered through partnerships with Washington Elementary School (WES) and a network of promotoras that are improving their community and interested in a community-based research

LEAF (Learning from and Engaging with Assessment and Feedback) Final project report

The LEAF (Learning from and Engaging with Assessment and Feedback) project was funded under the Teaching Fellowship in TU Dublin, city campus for 18 months beginning in January 2018. The project team comprised 18 academics from across the TU Dublin - City Campus and there are representatives from all colleges. Also included were two further members who represented the student voice: the Director of Student Affairs and the Students’ Union Education Officer. This project sought to address a key issue in third level Teaching and Learning, that of assessment and assessment feedback. Assessment strategies have been shown to have a large impact on shaping how students learn and how they develop key employability skills. Learning from best practice nationally and internationally, and research from staff, students and quality documents, this project has developed a set of recommendations which will enhance practices in, and experiences of, assessments and feedback in TU Dublin

Investigating the Potential and Pitfalls of EV-Encapsulated MicroRNAs as Circulating Biomarkers of Breast Cancer

Extracellular vesicles (EVs) shuttle microRNA (miRNA) throughout the circulation and are believed to represent a fingerprint of the releasing cell. We isolated and characterized serum EVs of breast tumour-bearing animals, breast cancer (BC) patients, and healthy controls. EVs were characterized using transmission electron microscopy (TEM), protein quantification, western blotting, and nanoparticle tracking analysis (NTA). Absolute quantitative (AQ)-PCR was employed to analyse EV-miR-451a expression. Isolated EVs had the appropriate morphology and size. Patient sera contained significantly more EVs than did healthy controls. In tumour-bearing animals, a correlation between serum EV number and tumour burden was observed. There was no significant relationship between EV protein yield and EV quantity determined by NTA, highlighting the requirement for direct quantification. Using AQ-PCR to relate miRNA copy number to EV yield, a significant increase in miRNA-451a copies/EV was detected in BC patient sera, suggesting potential as a novel biomarker of breast cancer
