Public Health Violence Prevention: Supporting Law Enforcement, Kira Swensen, Gabriela Murza, Sandra H. Sulzer, Maren Wright Voss

All Current Publications

As frustrations over inequalities in policing and law enforcement continue despite attempted reforms (Beckett, 2016), many are asking for a more effective approach. A 2018 issue statement from the American Public Health Association (2018) highlights that violence is a public health issue that will not go away without the influence of a public health approach. The integrated biological-psychological-social model of health recognizes the complexity in the ways individuals are influenced by their situations, with violence as the unfortunate result of the wrong mix of circumstances. The public health approach to violence focuses on prevention as part of the solution. This …

Effect Of Carbon Hybridization In C—F Bond As An Electron Donor In Triel Bonds, Qingqing Yang, Zongqing Chi, Qingzhong Li, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

The ability of the F atom of HC≡CF, H₂C=CHF and H₃CCH₂F to serve as an electron donor to the triel (Tr) atom of TrR₃ in the context of a triel bond is assessed by ab initio calculations. The triel bond formed by C_sp3—F is strongest, as high as 30 kcal/mol, followed by C_sp2—F, and then by C_sp—F whose triel bonds can be as small as 1 kcal/mol. The noncovalent bond strength diminishes in the order Tr = Al > Ga > B, consistent with the intensity of the π-hole …

Glucocorticoids, Energy Metabolites, And Immunity Vary Across Allostatic States For Plateau Side-Blotched Lizards (Uta Stansburiana Uniformis) Residing In A Heterogeneous Thermal Environment, Susannah S. French, Spencer B. Hudson

Browse all Datasets

Reptiles rely on thermal heat exchange to achieve body temperatures (Tbody) conducive to maintaining homeostasis. Diurnal changes in the thermal environment are therefore liable to influence allostatic mediation of survival processes (e.g., immunity) during environmental challenges or stressors. However, the extent to which Tbody prompts individual variation in physiology remains largely unexplored in reptiles. Our study tested how circulating energy-mobilizing hormone, energy metabolites, and immunity can vary across basal and stress-induced allostatic states for plateau side-blotched lizards (Uta stansburiana uniformis) residing in a heterogeneous thermal environment. We collected baseline and acute stress blood samples from male lizards to compare changes …

Memantine Treatment Reduces The Incidence Of Flaccid Paralysis In A Zika Virus Mouse Model Of Temporary Paralysis With Similarities To Guillain-Barré Syndrome, Venkatraman Siddharthan, Hong Wang, Alexandre Lr De Oliveria, Xin Dai, John D. Morrey

Animal, Dairy, and Veterinary Science Faculty Publications

Clinical evidence suggests that Zika virus contributes to Guillain-Barré syndrome that causes temporary paralysis. We utilized a recently described Zika virus mouse model of temporary flaccid paralysis to address the hypothesis that treatment with an N-methyl-D-aspartate receptor antagonist, memantine, can reduce the incidence of paralysis. Aged interferon alpha/beta-receptor knockout mice were used because of their sublethal susceptibility to Zika virus infection. Fifteen to twenty-five percent of mice infected with a Puerto Rico strain of Zika virus develop acute flaccid paralysis beginning at days 8–9 and peaked at days 10–12. Mice recover from paralysis within a week of onset. In …

Influence Of Chaperone-Like Activity Of Caseinomacropeptide On The Gelation Behaviour Of Whey Proteins At Ph 6.4 And 7.2, Sophie J. Gaspard, Prateek Sharma, Ciarán Fitzgerald, John T. Tobin, James A. O'Mahony, Alan L. Kelly, Andre Brodkorb

Nutrition, Dietetics, and Food Sciences Faculty Publications

The effect of caseinomacropeptide (CMP) on the heat-induced denaturation and gelation of whey proteins (2.5–10%, w/v) at pH 6.4 and 7.2, at a whey protein:CMP ratio of 1:0.9 (w/w), was investigated using differential scanning calorimetry (DSC), oscillatory rheology (90 °C for 20 min) and confocal microscopy. Greater frequency-dependence in the presence of CMP suggested that the repulsive interactions between CMP and the whey proteins affected the network generated by the non-heated whey protein samples. At pH 6.4 or 7.2, CMP increased the temperature of denaturation of β-lactoglobulin by up to 3 °C and increased the gelation temperature by up to …

Silent information regulator 1 and 2 (SIRT1, 2) were NAD+-dependent histone or non-histone deacetylase, which emerged as key metabolic sensors in several tissues of mammals. In the present study, the search for polymorphisms within the ovine SIRT1 and SIRT2 loci as well as association analyses between SNPs and growth-related traits were performed in Tibetan sheep. To determine the expression pattern of SIRT1 and SIRT2 genes in Tibetan sheep, the quantitative real-time polymerase chain reaction (qPCR) analysis revealed that those two genes were widely expressed in diverse tissues. Expression of SIRT1 was less in abomasum of lamb, whereas it …

Herbivores At The Highest Risk Of Extinction Among Mammals, Birds, And Reptiles, Trisha B. Atwood, Shaley A. Valentine, Edd Hammill, Douglas J. Mccauley, Elizabeth M. P. Madin, Karen H. Beard, William D. Pearse

Ecology Center Publications

As a result of their extensive home ranges and slow population growth rates, predators have often been perceived to suffer higher risks of extinction than other trophic groups. Our study challenges this extinction-risk paradigm by quantitatively comparing patterns of extinction risk across different trophic groups of mammals, birds, and reptiles. We found that trophic level and body size were significant factors that influenced extinction risk in all taxa. At multiple spatial and temporal scales, herbivores, especially herbivorous reptiles and large-bodied herbivores, consistently have the highest proportions of threatened species. This observed elevated extinction risk for herbivores is ecologically consequential, given …

Rapidly Accelerating Deforestation In Cambodia's Mekong River Basin: A Comparative Analysis Of Spatial Patterns And Drivers, Sapana Lohani, Thomas E. Dilts, Peter J. Weisberg, Sarah E. Null, Zeb S. Hogan

Watershed Sciences Faculty Publications

The Mekong River is a globally important river system, known for its unique flood pulse hydrology, ecological productivity, and biodiversity. Flooded forests provide critical terrestrial nutrient inputs and habitat to support aquatic species. However, the Mekong River is under threat from anthropogenic stressors, including deforestation from land cultivation and urbanization, and dam construction that inundates forests and encourages road development. This study investigated spatio-temporal patterns of deforestation in Cambodia and portions of neighboring Laos and Vietnam that form the Srepok-Sesan-Sekong watershed. A random forest model predicted tree cover change over a 25-year period (1993-2017) using the Landsat satellite archive. Then, …

The Role Of Carbonate Minerals In Arsenic Mobility In A Shallow Aquifer Influenced By A Seasonally Fluctuating Groundwater Table, Jeremy Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Arsenic (As) is a poison historically used to great effect before modern detection methods rendered it obsolete. However, the largest mass poisoning in human history occurred due to groundwater in the Bengal Basin contaminated by natural sources of As. Since that time, research has determined that As is found in groundwater worldwide. This includes aquifers located in basin-filled valleys of the western United States. One of these valleys is the Cache Valley Basin located in Northern Utah. This semi-arid region contains carbonate-rich soils and is heavily influenced by snowmelt and seasonal runoff. Previous studies have found that 15% of private …

Cytomegalovirus Inhibition By Pluronic-Encapsulated Quercetin And Synergy With Ganciclovir, Ian Wadsworth

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Congenital cytomegalovirus (CMV) is the leading viral cause of birth defects worldwide and leads to a variety of complications. Ganciclovir is the most common anti-CMV drug used but often causes severe side effects. Quercetin, a plant pigment, shows anti-CMV activity that may provide a less toxic alternative to ganciclovir, or when co-administered, reduce ganciclovir treatments. However, a drug carrier is needed to deliver quercetin for CMV treatment. In this study, three Pluronic polymers (P123, F127, and F68) were investigated as a quercetin drug delivery system (DDS) for CMV treatment.

All selected Pluronics successfully encapsulated quercetin at varying degrees of efficacy. …

The Effects Of Milk Phospholipids On Functional Properties Of Anhydrous Milk Fat And Oil Structured Gel Systems, Zachary Cooper

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lecithin is an ingredient commonly used in foods composed of high concentration of phospholipids. Phospholipids are a type of fat that can mix with both water and oil. In the current food industry, most lecithins come from sunflower, egg, and soybean sources. An additional source of phospholipids can be the waste streams from the dairy industry, such as the whey protein and butter making processes, since these contain a high concentration of phospholipids. Dairy phospholipids have been isolated in the past, but their traits as a functional ingredient are still unknown. In addition, most isolated dairy phospholipids still contain protein, …

Bioprocessing is leveraging cells to produce high value, lifesaving products. Precise environmental control is needed to maintain integrity of the bioprocessing production process. Temperature control requires both appropriate equipment choice and correct control parameter selection. To aid in the equipment selection process, enable better understanding of equipment capacity, and enable optimization of control parameters, a transient thermal model of both heat transfer characteristics and control systems was created in silico.

Harmful Algal Blooms: Dominance In Lakes And Risk For Cyanotoxin Exposure In Food Crops, Austin D. Bartos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Climate change and human activities are promoting the dominance of a photosynthetic family of aquatic bacteria, cyanobacteria. Blooms of cyanobacteria are not only a visual nuisance but can produce a variety of cyanotoxins than can harm the liver, skin, and nervous system of animals and humans. We analyzed lakes in the contiguous United States and found that between 2007 and 2012, the number of lakes that produced measurable quantities of cyanotoxins increased from 33% to 45%. Nitrogen and phosphorus pollution were the main drivers of cyanobacteria blooms and toxin production between these years. Many of these lakes and reservoirs are …

Exploring In Vivo And In Vitro Regulation Of The Shigella Type Three Secterion System Atpase Spa47, Heather B. Case

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Diarrheal disease is caused by a diverse group of enteric pathogens and is one of the leading causes of preventable deaths worldwide. Some of the most common causes of diarrheal disease are bacterial pathogens such as Salmonella, E. coli, Cholera, and Shigella. Many bacterial enteric pathogens use a type three secretion system (T3SS) to cause infection. The T3SS uses a needle and syringe like apparatus that allows the bacteria to inject proteins into the host cell to cause infection. Striking similarities in T3SSs from all pathogens that utilize them makes the T3SS an attractive target for …

Impacts Of Tourism On The Ecophysiology Of The Endangered Northern Bahamian Rock Iguana (Cyclura Cychlura), Alison C. Webb

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Increased interest in ecotourism over recent years has led to more direct human-animal interactions and a striking concomitant increase in the provisioning of non-natural food, that may have unintended consequences for the wildlife involved. The critically endangered Northern Bahamian Rock Iguana provides a valuable model to address the potential impact of food provisioning on health as there are populations that represent a graded variation in human presence, with sites experiencing high, low, or no tourism. To assess the potential impacts of tourism on iguana physiology I first reviewed the relevant literature on iguana physiology and then performed three investigations focusing …

Evaluating The Effect Of The Removal Of Non-Native Trout In Two High Elevation Tributary Streams In The Intermountain West, Clint Brunson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Native fish species such as Bonneville Cutthroat Trout (BCT) require cold, clear, well-connected streams for spawning and rearing as well as access to complimentary habitats. Increasing river temperatures and lower water flows may have allowed non-native Brown Trout (BNT) to migrate into higher elevation pristine streams. Additionally, anthropogenic actions such as stocking non-native Brown and Brook (BKT) and Rainbow Trout (RBT) for angling opportunities impact BCT. Invasion of these tributaries by non-native species may reduce or eliminate cutthroat trout by predation, competition, displacement, genetic suppression, and exclusion. A seven-fold increase in BNT numbers of 50 to 350 from 2017 to …
