Diet, Nutrition, And Substance Use Disorder, Mateja R. Savoie-Roskos, Ashley Yaugher, Alise Williams Condie, Gabriela Murza, Maren Wright Voss, Kandice Atisme

All Current Publications

Consuming a healthy diet can benefit everyone—especially individuals with substance use disorder (SUD), a disorder that occurs when frequent use of drugs or alcohol causes impairment, health issues, and difficulties with managing daily responsibilities (Substance Abuse and Mental Health Services Administration [SAMHSA], 2020). Although often overlooked, nutrition can play a key role in the treatment and recovery process for individuals with SUD, and should be included as part of a holistic approach toward recovery. In this fact sheet we will review how diet and nutrition are impacted during an active addiction, and the influence nutrition can have on treatment and …

“To Ask Freedom For Women”: The Night Of Terror And Public Memory, Candi Carter Olsen

Journalism and Communication Faculty Publications

On the night of November 14, 1917, 31 suffragists and members of the National Woman’s Party (“NWP”) were taken to Occoquan Workhouse in Virginia and tortured and beaten. This so-called “Night of Terror” captured national headlines at the time and has been memorialized through digital sites today. This article examines versions of the Night of Terror from the NWP’s official newspaper, The Suffragist, national newspapers of the day gathered from the Chronicling America database, and modern digital memorials of the event to understand the ways that the mediated telling of events create the fractured popular memories that are retold …

Aspen Next Generation: Conversations From Southern Colorado And Northern New Mexico, Dan Binkley, Bill Romme

Aspen Bibliography

Aspen trees and forests are especially important in the Rocky Mountains. Aspens add beauty to landscapes, foster high diversity and productivity of understory plants, provide for the habitat needs of many species of animals, and moderate fire behavior. There is a perception that aspen trees and stands are not regenerating well in southern Colorado and northern New Mexico; cohorts of trees younger than a few decades are scarce, at least in some areas. The next generation of aspen in the southern Rockies will be influenced by land use decisions, including harvesting, fire policy and management, and browsing by livestock and …

Fasting Diets: Are They Safe, Healthy, And Effective?, Carrie Durward, Keshele Stevens

All Current Publications

Diets are commonly prescribed to induce weight loss and reduce the risk of many diseases. Because a standard daily calorie restriction diet is often hard to maintain, other diet alternatives such as fasting diets were created. Fasting diets have been found to be effective, though they may not be any more effective than typical diets. Before beginning a fasting diet, it is best to seek professional medical advice to assess individual risks and circumstances. This fact sheet helps readers learn more about the safety, health, and effectiveness of fasting diets.

Added Sugars: What You Need To Know, Carrie Durward, Keshele Stevens

All Current Publications

Added sugar has become a hot topic among health professionals and in the media. Based on the best available evidence, health professionals recommend that less than 10% of daily calories come from added sugar (U.S. Department of Health and Human Services [HHS] & U.S. Department of Agriculture [USDA], 2015c) in order to maintain a balanced diet with all the important nutrients. In this fact sheet, we will address why and how to limit added sugar in your diet, what it is, and where to find it.

Human Development and Family Studies Faculty Publications

Divorce education programs are mandatory in most states. Despite the ongoing debate in the field regarding the appropriate duration of these programs, the goal of the current study was to identify the following five content areas in divorce education that may be most relevant for predicting favorable outcomes: (1) impact of divorce on children, (2) impact of divorce on family relationships, (3) financial responsibilities of divorcing parents for children, (4) benefits of positive coparenting, and (5) impact of domestic violence on children and family relationships. Using divorcing parents' self‐reported data (N = 3,275) from a one‐hour online divorce education …

Using Disaster Outcomes To Validate Components Of Social Vulnerability To Floods: Flood Deaths And Property Damage Across The Usa, Beth Tellman, Cody Schank, Bessie Schwarz, Peter D. Howe, Alex De Sherbinin

Environment and Society Faculty Publications

Social vulnerability indicators seek to identify populations susceptible to hazards based on aggregated sociodemographic data. Vulnerability indices are rarely validated with disaster outcome data at broad spatial scales, making it difficult to develop effective national scale strategies to mitigate loss for vulnerable populations. This paper validates social vulnerability indicators using two flood outcomes: death and damage. Regression models identify sociodemographic factors associated with variation in outcomes from 11,629 non-coastal flood events in the USA (2008–2012), controlling for flood intensity using stream gauge data. We compare models with (i) socioeconomic variables, (ii) the composite social vulnerability index (SoVI), and (iii) flood …

Solubility Of Carbon Dioxide In Renneted Casein Matrices: Effect Of Ph, Salt, Temperature, Partial Pressure, And Moisture To Protein Ratio, Prabin Lamichhane, Prateek Sharma, Alan L. Kelly, Jens Risbo, Fergal P. Rattray, Jeremiah J. Sheehan

Nutrition, Dietetics, and Food Sciences Faculty Publications

The solubility of carbon dioxide (CO2) in the moisture and protein components of cheese matrices and the influence of changing pH, salt and temperature levels remains unclear. In this study, model casein matrices were prepared, by renneting of micellar casein concentrate (MCC), with modulation of salt and pH levels by adding salt and glucono delta-lactone, respectively, to the MCC solutions prior to renneting. Different moisture-to-protein levels were achieved by freeze-drying, incubation of samples at different relative humidities, or by applying varying pressures during gel manufacture. The CO2 solubility of samples decreased linearly with both increasing temperature and salt-in-moisture content, whereas …

Effect Of Choline Forms And Gut Microbiota Composition On Trimethylamine-N-Oxide Response In Healthy Men, Clara E. Cho, Niklas D. J. Aardema, Madison L. Bunnell, Deanna P. Larson, Sheryl Aguilar, Janet R. Bergeson, Olga V. Malysheva, Marie A. Caudill, Machael Lefevre

Nutrition, Dietetics, and Food Sciences Faculty Publications

Background: Trimethylamine-N-oxide (TMAO), a choline-derived gut microbiota-dependent metabolite, is a newly recognized risk marker for cardiovascular disease. We sought to determine: (1) TMAO response to meals containing free versus lipid-soluble choline and (2) effects of gut microbiome on TMAO response. Methods: In a randomized, controlled, double-blinded, crossover study, healthy men (n = 37) were provided meals containing 600 mg choline either as choline bitartrate or phosphatidylcholine, or no choline control. Results: Choline bitartrate yielded three-times greater plasma TMAO AUC (p = 0.01) and 2.5-times greater urinary TMAO change from baseline (p = 0.01) compared to no choline and phosphatidylcholine. Gut …

Warner, Guillaume Poliquin, Kyle Rosenke, Kathy Frost, Kevin Tierney, Greg Saturday, Jinxin Miao, Jonna B. Westover, Brian B. Gowen, Stephanie Booth, Heinz Feldmann, Zhongde Wang, David Safronetz

Animal, Dairy, and Veterinary Science Faculty Publications

Crimean-Congo hemorrhagic fever virus (CCHFV) is a tick-borne pathogen causing a febrile illness in humans, which can progress to hemorrhagic manifestations, multi-organ failure, and death. Current mouse models of CCHFV infection reliably succumb to virus challenge but vary in their ability to reflect signs of disease similar to humans. In this study, we established a signal transducer and activator of transcription 2 (STAT2) knockout hamster model to expand the repertoire of animal models of CCHFV pathogenesis that can be used for therapeutic development. These hamsters demonstrated a systemic and lethal disease in response to infection. Hallmarks of human …

Information Search And Financial Markets Under Covid-19, Behzod B. Ahundjanov, Sherzod Akhundjanov, Botir B. Okhunjanov

Applied Economics Faculty Publications

The discovery and sudden spread of the novel coronavirus (COVID-19) exposed individuals to a great uncertainty about the potential health and economic ramifications of the virus, which triggered a surge in demand for information about COVID-19. To understand financial market implications of individuals’ behavior upon such uncertainty, we explore the relationship between Google search queries related to COVID-19—information search that reflects one’s level of concern or risk perception—and the performance of major financial indices. The empirical analysis based on the Bayesian inference of a structural vector autoregressive model shows that one unit increase in the popularity of COVID-19-related global search …

Seed-Transmitted Wheat Mosaic Virus In Sweet Corn In Utah, Claudia Nischwitz

Biology Faculty Publications

Wheat mosaic virus (WMoV) (syn. High Plains virus) was first observed in corn in 1993 in Colorado, Idaho, Kansas, and Texas (Seifers et al. 1997). The virus causes chlorotic streaks and mosaic on corn foliage, and it stunts ear development. When infected early in the season, plants frequently die. There are anecdotal reports of reduced seed germination rates in infected seed lots. The host range of the virus includes corn, small grains, and yellow and green foxtail. The virus is transmitted by the wheat curl mite (Aceria tosichella Keifer 1969). Seed transmission of WMoV at extremely low rates was …

Fire Suppression Impacts On Fuels And Fire Intensity In The Western U.S.: Insights From Archaeological Luminescence Dating In Northern New Mexico, Christopher I. Roos, Tammy M. Rittenour, Thomas W. Swetnam, Rachel A. Loehman, Kacy L. Hollenback, Matthew J. Liebmann, Dana Drake Rosenstein

Geosciences Faculty Publications

Here, we show that the last century of fire suppression in the western U.S. has resulted in fire intensities that are unique over more than 900 years of record in ponderosa pine forests (Pinus ponderosa). Specifically, we use the heat-sensitive luminescence signal of archaeological ceramics and tree-ring fire histories to show that a recent fire during mild weather conditions was more intense than anything experienced in centuries of frequent wildfires. We support this with a particularly robust set of optically stimulated luminescence measurements on pottery from an archaeological site in northern New Mexico. The heating effects of an October 2012 …

Do Plant Secondary Metabolite‐Containing Forages Influence Soil Processes In Pasture Systems?, Andrea K. Clemensen, Juan J. Villalba, George E. Rottinghaus, Stephen T. Lee, Frederick D. Provenza, Jennifer R. Reeve

Wildland Resources Faculty Publications

Grazed pastures are susceptible to N loss from urine/manure additions, which increases eutrophication, affecting the global N cycle. Plant secondary metabolites (PSM), such as condensed tannins (CT) and terpenes, influence silviculture soil dynamics by generally decreasing N mineralization. We investigated whether cattle‐grazed pastures of non‐traditional grass and legume forage monoculture strips including CT‐containing sainfoin (Onobrychis viciifolia Scop.) and tall fescue (TF) [Schedonorus arundinaceus (Schreb.) Dumort.] influenced soil dynamics compared with traditional grass and legume forage monoculture strips of alfalfa (Medicago sativa L.), without tannins, and TF. Throughout the study, CT in sainfoin averaged 58.9 g kg^{−1 …}

Coqui Frog Predator Avoidance And Recognition, Karen H. Beard

Browse all Datasets

The purpose of this study was to determine whether coqui frogs from their non-native range responded to native predators the same way as frogs from their native range. Frogs were collected from two sites in Puerto Rico (El Yunque and Rio Abajo) in May 2006 and one site in Hawaii (Hilo) in June 2006. At each site, frogs were collected from a high (> 700 m) and low (< 300 m) elevation population. Of the total number of frogs collected, 100 males were randomly selected to be used in this study (45 and 55 from Hawaii and Puerto Rico, respectively). Three tailless whipscorpions (Phrynus longipes) and three tarantulas (Avicularia laeta) were also collected in Puerto Rico in field sites where frogs were collected and shipped back to a laboratory.

Promoting Healthy Decision-Making Via Natural Environment Exposure: Initial Evidence And Future Directions, Meredith S. Berry, Meredith A. Repke, Alexander L. Metcalf, Kerry Jordan

Psychology Faculty Publications

Research within psychology and other disciplines has shown that exposure to natural environments holds extensive physiological and psychological benefits. Adding to the health and cognitive benefits of natural environments, evidence suggests that exposure to nature also promotes healthy human decision-making. Unhealthy decision-making (e.g., smoking, non-medical prescription opioid misuse) and disorders associated with lack of impulse control [e.g., tobacco use, opioid use disorder (OUD)], contribute to millions of preventable deaths annually (i.e., 6 million people die each year of tobacco-related illness worldwide, deaths from opioids from 2002 to 2017 have more than quadrupled in the United States alone). Impulsive and unhealthy …

Preparing And Improving Garden Soil, Katie Wagner, Melanie Stock, Larry A. Sagers

All Current Publications

A great garden starts with healthy soil. In Utah, there are unique considerations for creating and maintaining healthy soils. Native Utah soils are relatively low in organic matter. One of Utah’s most troublesome, pH-related deficiencies is iron chlorosis, a deficiency of plant-available iron. Soil salinity easily increases in Utah. This fact sheet addresses these challenges to help gardeners transform garden soils from brutal to beautiful!

Contested Dam Development In Iran: A Case Study Of The Exercise Of State Power Over Local People, Elham Hoominfar, Claudia Radel

Sociology, Social Work and Anthropology Student Research

In this article, we address the interaction of the Iranian State, an agent of power, with affected village residents, as four dam projects are planned and implemented. Dams, recently positioned as a green energy source, are a central component to Iran’s national development strategies; yet historically their construction has been a source of significant conflict and resistance around the world. We focus on ten villages facing displacement or partial loss of lands at the time of the research, and we answer the question: During dam building and resettlement processes, how have residents experienced their role in decision making and the …

In Vitro Digestibility Of Mountain-Grown Irrigated Perennial Legume, Grass And Forb Forages Is Influenced By Elevated Non-Fibrous Carbohydrates And Plant Secondary Compounds, Yunhua Zhang, Jennifer W. Macadam, Juan J. Villalba, Xin Dai

Plants, Soils, and Climate Faculty Publications

BACKGROUND

Perennial legumes cultivated under irrigation in the Mountain West USA have non‐fibrous carbohydrate (NFC) concentrations exceeding 400 g kg−1, a level commonly found in concentrate‐based ruminant diets. Our objective was to determine the influence of NFC concentration and plant secondary compounds on in vitro rumen digestion of grass, legume and forb forages compared with digestion of their isolated neutral detergent fiber (NDF) fraction. Forages were composited from ungrazed paddocks of rotationally stocked, irrigated monoculture pastures between May and August 2016, frozen in the field, freeze‐dried, and ground.

RESULTS

The maximum rate (RMax) of gas production was greater for the …

Raman Spectroscopy Characterization Extracellular Vesicles From Bovine Placenta And Peripheral Blood Mononuclear Cells, Han Zhang, Ana Caroline Silva, Wei Zhang, Heloisa M. Rutigliano, Anhong Zhou

Animal, Dairy, and Veterinary Science Faculty Publications

Placenta-derived extracellular vesicles (EVs) are involved in communication between the placenta and maternal immune cells possibly leading to a modulation of maternal T-cell signaling components. The ability to identify EVs in maternal blood may lead to the development of diagnostic and treatment tools for pregnancy complications. The objective of this work was to differentiate EVs from bovine placenta (trophoblast) and peripheral blood mononuclear cells (PBMC) by a label-free, non-invasive Raman spectroscopy technique. Extracellular vesicles were isolated by ultracentrifugation. Dynamic light scattering (DLS) and scanning electron microscopy (SEM) were applied to verify the presence and the size distribution of EVs. Raman …

Application Of A Cascade Membrane Filtration Process To Standardise Serum Protein Depleted Cheese Milk For Cheddar Cheese Manufacture, Xiaofeng Xia, John B. Tobin, Prateek Sharma, Mark Fenelon, Paul L.H. Mcsweeney, Jeremiah J. Sheehan

Nutrition, Dietetics, and Food Sciences Faculty Publications

A cascade membrane filtration process including microfiltration (MF), ultrafiltration (UF) and reverse osmosis (RO) was used to fractionate skim milk into different streams. Significant quantities of lactose and minerals were removed to permeate after MF at 0.14 μm. Cheese milk, of similar casein content to the raw milk, was standardised simultaneously for casein, lactose, ash and total calcium from the membrane streams without requiring CaCl2 and lactose addition. Serum protein depleted cheese milk of typical casein content had similar rennet coagulability, cheese composition, texture and yield to the control; milk of 1.5 × casein content had a faster coagulation rate …

Urban Garden Soils: Testing And Management, Melanie Stock, Tiffany Maughan, Paul R. Grossl

All Current Publications

This fact sheet provides step-by-step instructions on selecting appropriate soil tests, sampling, and interpreting results. Soil tests measure plant nutrient needs and soil contamination, both important aspects of sustainable urban gardening. Although many garden centers sell home soil test kits, these tests are not recommended because they were developed outside of the Intermountain West with soils that have nearly opposite conditions. Soil tests conducted in local labs may cost more initially, but will provide results specific to Utah soils and management recommendations that balance long-term soil productivity, human health, and environmental sustainability. The Utah State University Analytical Labs (USUAL) is …

Equine Nutrition: Concentrates, Karl Hoopes, Patricia Evans, Scott Mckendrick

All Current Publications

Concentrate (grain) should be considered only as supplements to good quality hay. In general, a mature horse does not require the energy provided by concentrate-type feeds (grains/sweet feeds, pelleted feed, etc.) unless the horse is used for more than light work or in production, such as a lactating mare or a breeding stallion. Too many times horses are overfed rather than underfed. This fact sheet will help horse owners understand the digestive process and the general feeding requirements, including different grains and mixed grains, for their horses.

Water Development, Consumptive Water Uses, And The Great Salt Lake, Sarah E. Null, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

Great Salt Lake (GSL) covers 5500 km² (2100 mi²) at its unimpacted elevation and is the eighth largest saline lake in the world. Its highly productive food web supports millions of migratory birds and the economic value of the lake is estimated at $1.5 billion US dollars in 2019. Droughts and wet cycles have caused huge fluctuations in lake level, area, and salinities, and this variation has masked anthropogenic impacts. Recent work, however, has determined that consumptive water uses in the watershed have depleted inflows by approximately 39%, with 63% used by agriculture, 11% by cities, 13% …

Restoring Lake Urmia: Moving Beyond A Uniform Lake Level (2-Page Summary), Somayeh Sima, Dory Rosenberg, Wayne A. Wurtsbaugh, Sarah E. Null, Karin M. Kettenring

Watershed Sciences Faculty Publications

More than 5 million people live near Lake Urmia in northwestern Iran, one of the world's largest hypersaline lakes. Over the past two decades, the lake has lost 95% of its volume, lake level has dropped more than 7 m, and lake restoration has gained widespread interest. The government seeks a uniform "ecological" target lake level of 1274.1 m above sea level to lower salinity below 240 gL^-1 and recover brine shrimp (Artemia spp.) and flamingos (Phoenicopterus roseus).
