High Altitude Ballooning As A Platform For Measuring Ozone Uptake Over Agricultural Landscapes, Thomas Sykora, Mark Potosnak Aug 2021

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 …


Quantifying Greenhouse Gas Flux Of Restored Vs. Unrestored Wetlands: A Case Study At Prairie Wolf Slough, Matthew Connors, Beth Lawrence Jul 2016

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 May 2015

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 …
