The coexistence of two ecologically similar species could be explained by differential use of microhabitats. This study investigated factors that influence foraging and web building behavior of two invasive species of arthropod predators in the family Pholcidae. Both are well-adapted to human dwellings, with Pholcus phalangioides, the larger species, undergoing displacement in Southwest Ohio by […]
A49: Carnitine Degradation in an Isolated Strain of the Gut Bacterium Citrobacter amalonaticus
The gut microbiome is home to several species of bacteria and other microorganisms that play an essential role in human health. For example, the normal bacteria in our gut provide resistance to pathogenic species and directly impact nutrient metabolism, such as the production of vitamin K. Carnitine, which is a molecule commonly found in seafood […]
A48: Seeing a Future Together: The Potential for Health Programs to Reduce Avoidable Blindness in Rural Communities
My project is about avoidable blindness in rural areas of the United States and is analyzed through the lens of global health. The work was conducted with a mix of in-field work and academic work. My immersion experience involved spending 7 weeks immersed in rural Honduras. During this time I shadowed physicians and community health […]
A47: Depicting Inequities in Oral Health: Barriers to Dental Care Among Marginalized Groups in the U.S.
This project is the final component of Global Health Studies immersion experience. I completed this experience at two different dental clinics within the Cincinnati Health Network. I shadowed dental professionals for approximately 40 hours, taking detailed field notes for qualitative research, in addition to my literature research. Oral health is one of the most integral, […]
A46: Impact of Chlamydia on Caspase Activation
The purpose of this experiment was to determine if Chlamydia psittaci is inhibiting caspase activation in HeLa cells through the sequestering of ceramide. This was done by treating cells infected with C. psittaci, as well as uninfected cells, with increasing concentrations of C6-ceramide. A fluorometric multiplex activity assay was used to measure caspase activation.It was […]
A44: HVSR Analysis of Heterogenous Buried Glacial Valley Deposits, Southwestern Ohio
This study presents the results of a detailed Horizontal-to-vertical spectral ratio (HVSR) passive-seismic recording program in glacial filled-valley deposits in southwestern Ohio. Study goals were to evaluate the sensitivity of the HVSR method and best practices regarding field sampling techniques and data analysis. The study was conducted in the valley of Four Mile Creek near […]
A42: MBI475: The Effects of Environmental Stressors on Antarctic Algae
This study was intended to identify the impact of salt concentrations on the diversity of Antarctic microbial taxa. Lakes in the McMurdo Dry Valley(MDV) of Antarctica are permanently covered with 3-5 meters of ice and have substantially increasing salt concentrations as the depth increases in the lakes. Salinity is a harsh stressor for most organisms […]
A43: Actinobacteria and Their Link to Unique Microbial Ecosystems in the Taylor Dry Valleys, Antarctica
Extremophiles, organisms that live in environments outside of the conditions that are well suited to life, need incredible amounts of adaptation to survive. One of the most extreme environments on earth are the lakes in the Taylor Dry Valleys in Antarctica. These lakes are subject to the polar night, as well as increased radiation.Low precipitation […]
A45: Applications of Dimethyl Carbonate for the HILIC Separation of Sugars with Charged Aerosol Detection: Greening Industrial Solvents
We have researched the use of the green solvent dimethyl carbonate (DMC) as a mobile phase modifier for different forms of chromatography, such as hydrophilic liquid interaction chromatography (HILIC), normal phase liquid chromatography, and reversed phase liquid chromatography. Our lab’s recent publication demonstrates the utility of non-toxic and biodegradable DMC as a replacement for the […]
A41: Unusual Cell Division in Cell Wall-less Bacteria
Cell division in most bacteria is a highly organized, regular process in which a single cell gives rise to two essentially equivalent daughter cells. Division is coordinated with parent cell growth and DNA replication and dependent upon cell wall synthesis. Mycoplasma is a genus of very small bacteria resulting from reductive evolution of the genome, […]
