Street Outreach And Reentry: The Role Of Community Violence Intervention In The Reintegration Of Returning Citizens, Hilary Jackl

Electronic Theses & Dissertations (2024 - present)

Amidst ongoing efforts to reduce the nation’s prison population, as well as calls to defund the police and invest in civilianized public safety strategies following the murder of George Floyd, community-based violence intervention (CVI) strategies have been increasingly recognized as a critical means by which to ameliorate the United States’ enduring gun violence problem without exacerbating the harms of overpolicing and mass incarceration. However, most contemporary CVI research has assessed program impacts on neighborhood rates of gun violence and has produced conflicting findings, leading scholars to call for the need to examine a wider range of program-related functions and outcomes. …

Comparison Of Methane Emission Quantification Methods At Landfills In New York State, Alexandra M. Catena

Electronic Theses & Dissertations (2024 - present)

Greenhouse gas (GHG) emission increases are a consequence of global population rise and economic growth. It is well known that carbon dioxide is the dominant GHG by mass, but methane has received increasing attention recently due to its high warming potential and relatively short lifetime of about a decade. Methane has several different types of both natural and anthropogenic sources including wetlands, waste management, energy, agriculture and farming, and wildfires, which makes tracking and reducing methane emissions a complex problem. The emission rates of each of these sources are highly uncertain due to differing emission estimation methods, which can be …

Postnatal Programming Of Infant Temperament At 12-Months: A Test Of Lactation Programming Theory, Lydia Bierce

Electronic Theses & Dissertations (2024 - present)

The current study examined how maternal cortisol and breastfeeding duration across the first six months postpartum might relate to infant temperament profile membership at 12 months in 322 low-income Mexican American mother-infant dyads (46.3% male). Results revealed that maternal postnatal cortisol levels were significantly moderated by breastfeeding duration to predict infant temperament profile (β = 0.14, p = .030) such that more maternal cortisol was linked to higher likelihood of belonging to a high positive affect, well-regulated profile when mothers breastfed for above average durations. This suggests that while maternal cortisol in breastmilk might initially shape infant negative temperament, …

Environmentally Persistent Free Radicals Lead To Selective Inhibition Of Cyp1 Monooxygenase Activities, And Increased Production Of Reactive Oxygen Species By Reaction Uncoupling, John Patrick Connick, Amari A. Stepter, George F. Cawley, Marilyn K. Eyer, Wayne L. Backes

School of Medicine Faculty Publications

This study focuses on the effect of Environmentally Persistent Free Radicals (EPFRs) on the P450 enzymes of the CYP1 family. EPFRs are a component of particulate pollutants, that are stable in the environment, but can generate free radicals, leading to oxidative stress and subsequent toxicity of the respiratory, cardiovascular, and immune systems once they enter an organism. The results show differences in the ability of EPFRs to inhibit CYP1-dependent substrate metabolism, with CYP1B1 being inhibited to the greatest extent. There also were differences in the ability of EPFRs to disrupt the POR•CYP1 complex, with CYP1B1 being the only form where …

Chronic Administration Of A Cannabis-Derived Mixture At An Antihyperalgesic Dose Does Not Significantly Enhance Hepatotoxicity Or The Development Of Metabolic Dysfunction-Associated Steatohepatitis In Male Mice, Kim B. Pedersen, Tomislav Jelesijevic, Tamara M. Morris, Sarah M. Melton, Ashley S. Henderson, John F. Glenn, Gregory J. Davenport, Martin J.J. Ronis, Peter J. Winsauer

School of Medicine Faculty Publications

Cannabis and cannabinoid mixtures have been linked to a variety of health benefits including pain mitigation, suppression of nausea produced by chemotherapeutic agents, anti-inflammatory effects, and effects on energy homeostasis, glucose, and lipid metabolism. The latter properties have led to the suggestion that these products could have therapeutic effects on the development of metabolic dysfunction-associated steatohepatitis (MASH) - a severe type of liver pathology in obese and diabetic patients. However, varying agonist and antagonistic properties of different cannabinoids on the endogenous cannabinoid system make prediction regarding hepatic effects and diet interactions difficult. The current study was designed to examine hepatic …
