- The Anti-microbial Properties of Silver found in Alagon by Christina Scalzo.
Silver has long been known for its antimicrobial properties, but its uses within the industry have been limited. This led to exploring the properties of a byproduct, Alagon, which contains small amounts of silver. In order to prove its antimicrobial properties, several studies have been conducted to observe growth of bacteria under different treatments. The growth of bacteria was observed on varying surfaces (i.e. paper, cardboard, plastic etc.) before being placed on a bacteria plate or treated. Two methods are used to test treatment; coating cotton swabs in Alagon to transfer bacteria and a full coverage dusting of Alagon on each surface. Each surface was plated on different augers (TSA, Malt, and Columbia blood) and compared between treated and untreated, from this percent inhibition was calculated. Initial studies show that Alagon has an inhibitory effect, with a preliminary inhibition of 80%?90% for the dusted treated plates and 30%?70%. The data collected thus far has led the research to exploring different concentrations of silver in Alagon, varying surface area exposed, and new testing procedures as the next step. Future studies will include the use of liquid cultures, using analysis via UV-Vis spectroscopy, allowing the enhancement of analytical results. ( ,,,, )
- Urinary lead and arsenic are associated with carotid intima media thickness in CNY children by Charlotte Labrie-Cleary.
A set of tools within a statistical program called RStudio was used to explore the associations between urinary metals and the cardiovascular disease potential in 300 children between the ages 9 and 12 years old from Syracuse NY, as part of the Environmental Exposures and Child Health Outcomes study. A total six covariables were used to account for potential confounders contributing to cardiovascular/psychological health: race, child age, gender, BMI percentile, and socioeconomic status z-score. The concentration of creatinine in the urinary samples was measured in the summer of 2020 in our laboratory. When running correlation analysis between urinary metals and creatinine in this study, it was found that all such associations were highly significant. For this reason, the concentration of heavy metals in our urinary samples was adjusted for the individual creatinine level within each subject. Following this adjustment, a strong association between the concentration of lead and arsenic and carotid intima media thickness was discovered. Itâ€™s a novel an important finding. Future work will expand correlation analysis to psychological parameters.
