High Altitude Ballooning As A Platform For Measuring Ozone Uptake Over Agricultural Landscapes, Thomas Sykora, Mark Potosnak
High Altitude Ballooning As A Platform For Measuring Ozone Uptake Over Agricultural Landscapes, Thomas Sykora, Mark Potosnak
DePaul Discoveries
Measuring plant health is a key aspect in maximizing crop outputs. One often overlooked risk to crop fields is damage caused by stomatal ozone uptake; measuring this uptake is an important tool in understanding crop losses. Traditional methods for measuring plant ozone uptake are prohibitively expensive and rely on equipment that cannot easily be moved. Here, we propose high-altitude weather ballooning as a cost-effective alternative for measuring ozone uptake on a regional (~10 km) spatial scale. Ozonesounde data was obtained with weather balloons launched from the National Oceanic and Atmospheric Administration research station in Boulder, Colorado. This data was then …

The Open Neuroscience Initiative is a free-to-use textbook
This project began as a means to overcoming the financial burden that face undergraduate neuroscience students when buying textbooks. By compiling and writing a completely free-to-access textbook that covers the foundations of a typical college introduction to neuroscience course, students would have one less obstacle to overcome in their educational career, allowing them to focus their valuable time and attention on learning rather than finances. To make this project a reality, I began with a humble tweet in May 2019 that managed to gain a tiny bit of traction among the neuroscience …
Quantifying Greenhouse Gas Flux Of Restored Vs. Unrestored Wetlands: A Case Study At Prairie Wolf Slough, Matthew Connors, Beth Lawrence
Quantifying Greenhouse Gas Flux Of Restored Vs. Unrestored Wetlands: A Case Study At Prairie Wolf Slough, Matthew Connors, Beth Lawrence
DePaul Discoveries
Wetlands provide ecological services such as cleansing the water supply, sequestering carbon, and providing habitat for wildlife, however wetland restoration often alters the greenhouse gas flux of the site. Our study aims to investigate the effects of wetland restoration on greenhouse gas flux at Prairie Wolf Slough. We did this by comparing greenhouse gas flux on matching hydric soil series from the restored wetland with an adjacent abandoned agricultural field. We measured known controls of greenhouse gas flux such as soil moisture and soil temperature. We found that there was no detectable methane and nitrous oxide flux at either site, …
Chronic Inflammation As A Result Of Hepatitis C Virus Infection: A Review Of The Literature, Samantha L. Lane
Chronic Inflammation As A Result Of Hepatitis C Virus Infection: A Review Of The Literature, Samantha L. Lane
DePaul Discoveries
Approximately 170 million people are infected with Hepatitis C virus (HCV) worldwide5,6. It is estimated that roughly 80% of those infected suffer from persistent infection with the virus; this persistence of infection is progressive, and over time can lead to fibrosis, cirrhosis, and hepatocellular carcinoma7. Chronic inflammation and apoptotic deregulation are both hallmarks of chronic HCV infection, and many molecular pathways are initiated in both the innate and adaptive immune responses during infection with this viral pathogen. The aim of this review was to survey some of the major molecular mechanisms responsible for the induction of …
Roles Of Resveratrol And Genistein In Invasion And Metastasis Of Breast Cancer, Brittany Wolfe
Roles Of Resveratrol And Genistein In Invasion And Metastasis Of Breast Cancer, Brittany Wolfe
College of Science and Health Theses and Dissertations
Breast cancer is a cellular disease characterized by the exploitation of several cellular and molecular mechanisms involved in cell proliferation, apoptosis, motility, and invasion. Effective treatment is available for non-invasive breast cancer at diagnosis, leading to a very high survival rate compared to the low survival rate for those where the breast cancer has spread. Thus, identifying effective therapies and preventative agents is imperative to successfully treat breast cancer. Since diet compromises a large component of the risk factors for breast cancer, it would be beneficial to examine dietary compounds that could potentially play a beneficial role in inhibiting cancer …
A Study Of Histone Deacetylase Inhibitors: Determination Of The Binding Energetics Of Suberoylanilide Hydroxamic Acid With Zinc And Cobalt And Preliminary Screening Of Nitric Oxide Donors, Erin Gallagher
College of Science and Health Theses and Dissertations
Inhibiting histone deacetylases (HDACs) can suppress tumor cell growth eventually leading to their death, makeing HDACs an important drug target. Therefore, understanding the mechanism behind inhibiting HDACs is imperative. To determine the thermodynamic parameters for the interaction of a known competitive HDAC inhibitor, suberoylanilide hydroxamic acid (SAHA), with zinc(II), the metal ion in the HDAC active site, and cobalt(II), isothermal titration calorimetry (ITC) was used. The results showed that SAHA binds to zinc(II) more strongly than it does to cobalt(II) as the equilibrium binding constants were 4.3 ± 0.5 x 102 M-1 and 2.0 ± 0.5 x 10 …
