Retinoic Acid Hydroxylase Inhibitors As A Novel Therapy For Alzheimer’S Disease, Isabel M. Makman

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Alzheimer’s Disease (AD) is one of the most prevalent neurodegenerative diseases afflicting the modern world. As no cure for AD has yet been discovered we sought to explore a potential treatment option based on the inhibition of retinoic acid (RA) metabolism, the active metabolite of vitamin A. Beta-amyloid plaques form in the brain and decrease cognitive function in AD patients. In a recent preclinical study RA was shown to decrease these plaques and rescue memory deficits in an Alzheimer’s mouse model[i]. One key limitation is that when RA is administered to humans it induces its own breakdown, making …

Crop Swap Missoula: Food Waste And The Sharing Solution, Cathryn Raan

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Rachel Botsman coined the term “collaborative consumption” to describe an economic model based on sharing, swapping, trading, or renting products and services, and enabling access rather than ownership¹. Also referred to as the sharing economy, the mesh economy, or the peer-to-peer economy, collaborative consumption models offer a more efficient use of unused, or underutilized resources. Whereas previously peer-to-peer exchanges were only practical within small networks of friends, family, and neighbors, the Internet and mobile technology have allowed us to share almost anything at any time. While there are countless examples of community exchange platforms, and more springing up …

Contrasting Two Prophylactic Dysphagia Interventions For Patients With Head And Neck Cancer Treated With Radiotherpy With Or Without Adjunctive Chemotherapy, Laurie Slovarp

Graduate Student Theses, Dissertations, & Professional Papers

Many patients with head and neck cancer (HNC) suffer from dysphagia caused by organ preserving regimens of radiation therapy with or without adjunctive chemotherapy. Prior research has shown a benefit of prophylactic dysphagia intervention; however, prior studies vary in terms of timing, dosage, and types of treatments prescribed. Additionally, compliance to prophylactic swallowing exercises (PSEs) has been poor and anecdotal evidence points towards swallowing pain as a cause of poor compliance. This prospective study investigated exercise compliance, oral intake, self-perceived swallowing function, swallowing-related quality of life, and swallowing-related pain for patients who received two different types of prophylactic swallowing interventions. …

An Assessment Of Biochar Amended Soilless Media For Nursery Propagation Of Northern Rocky Mountain Native Plants, Clarice P. Matt

Graduate Student Theses, Dissertations, & Professional Papers

A study was conducted to better inform nursery practitioners of the potential benefits of biochar application in common nursery media for native plant propagation. Biochar – a carbon-rich, recalcitrant charred organic co-product of the bioenergy pyrolysis process – has emerged as a promising potential replacement for various components of soilless media, namely peat, perlite, and vermiculite, in nursery seedling propagation. A strong conceptual basis exists for biochar as a nursery media amendment, but empirical data on biochar-based plant propagation is limited. This greenhouse study examined the effects of biochar displacement of standard soilless nursery media at rates of 0%, 15%, …

Participants wore standard WLFF Nomex green pants, Nomex yellow shirt with …

The Sensitivity Of Soil Respiration To Soil Temperature, Moisture, And Carbon Supply At The Global Scale, Andrew Hursh

Graduate Student Theses, Dissertations, & Professional Papers

Soil respiration is one of the most important terms in the global carbon budget, yet we know very little about how important environmental factors control this process at the global scale. Soils contain more carbon than terrestrial biomass and the atmosphere combined and contribute ten times more carbon dioxide to the atmosphere each year than the burning of fossil fuels. This study provides new insight on the factors driving soil respiration at the global scale by assimilating satellite observations of soil moisture, temperature, and net primary productivity with the Global Soil Respiration Database (SRDB).While temperature, moisture, carbon supply and other …

The Last Wolves Of Isle Royale, Kasey Rahn

Graduate Student Theses, Dissertations, & Professional Papers

Isle Royale National Park, located in Michigan, is home to a wolf population that is in decline due to complications from inbreeding. Scientists and managers struggle to decide whether to intervene. Some scientists promote bringing new wolves to the island to restore the population because they say the decline is human-caused. Others promote “watchful waiting.” To date, the National Park Service has not interceded and is currently undergoing a management planning process. The issue raises questions about what it means to manage wildlife in an era of change. Should humans intervene to protect wildlife in the face of climate change …

The Drunken Path: Discerning Women's Voices And Participation In The Informal Economy Of Illegal Manufacturing Of Prohibition Alcohol In The Historical And Archaeological Record, Kelli M. Casias

Graduate Student Theses, Dissertations, & Professional Papers

This thesis puts the Prohibition years in Anaconda and Butte, Montana, into historical, and sociocultural context to discover an engendered narrative of liquor law violators between the years 1923 and 1926 and to investigate the scope of the local informal, illegal, illicit economic systems dictating the distribution of illegal liquor during that era. The transference of the means and modes of production, as envisioned by Karl Marx, and collective social resistance serve as the theoretical frameworks for analysis and examination of three case studies. The first, Poacher Gulch is a remote mining site in western Montana, was the subject of …

Linking The Effects Of Risk Factors On Annual Calf Survival To Elk Population Dynamics In The Bitterroot Valley, Montana, Daniel R. Eacker

Graduate Student Theses, Dissertations, & Professional Papers

The recolonization of gray wolves (Canis lupus) in multiple carnivore systems has been correlated with declining recruitment of juvenile ungulates, but the importance of wolves relative to other established carnivores is uncertain. The realized effect of carnivores may depend on compensation from forage and winter weather severity, which may mediate juvenile vulnerability to predation. Also, in high predation systems, the importance of juvenile recruitment may be reduced for ungulate population dynamics. We first tested for the effects of risk factors on annual elk (Cervus elaphus) calf survival and estimated cause-specific mortality rates. Secondly, we investigated the …

Maximal Femoral Artery Blood Flow During Cycle Ergometry, Tucker W. Squires

Graduate Student Theses, Dissertations, & Professional Papers

MAXIMAL FEMORAL ARTERY BLOOD FLOW DURING CYCLE ERGOMETRY

Chairperson: Matthew Bundle Ph.D.

The delivery of oxygen to working muscle in order to support aerobic respiration has long been recognized as one of the critical elements conferring endurance performance. Oxygen is transported from the environment to the active cells by the cardiovascular system, which is classically understood to deliver progressively greater amounts of gas to support increased levels of aerobic metabolism. However, the vast majority of existing studies have used modes of exercise that activate relatively small volumes of muscle and consequently have relatively small demands for oxygen delivery. We measured …

Coevolution And Cospeciation In A Bark-Beetle Fungal Symbiosis, Ryan Russell Bracewell

Graduate Student Theses, Dissertations, & Professional Papers

Bark beetles in the genus Dendroctonus are some of the most important insects in forest ecosystems worldwide and are known to be involved in symbiotic relationships with fungi. However, we have a poor understanding of beetle-fungal coevolution and if the specificity we see in beetle-fungal relationships may translate to cospeciation over longer time frames. In this dissertation, I attempt to answer these questions by investigating the western pine beetle (Dendroctonus brevicomis)-fungal symbiosis, a beetle that consists of two putative cryptic species in the early stages of divergence on two susbspecies of ponderosa pine (Pinus ponderosa). In the first chapter, I …

Does Migration Matter? Causes And Consequences Of Migratory Behavior In Sierra Nevada Bighorn Sheep, Derek Benjamin Spitz

Graduate Student Theses, Dissertations, & Professional Papers

Despite their potential conservation importance, the demographic implications of migratory behavior remain poorly understood. Sierra Nevada bighorn sheep (Ovis canadensis sierrae; hereafter “Sierra bighorn”) are federally-endangered and partially migratory. In summer, Sierra bighorn share high-elevation summer ranges, but in winter some individuals migrate to lower elevation for winter while others remain resident at high-elevation. Lower elevations have better forage in winter, but these areas also carry an increased risk of predation from Sierra bighorn's primary predator, the cougar (Puma concolor). We should therefore expect differences in winter conditions to result in demographic differences between migrants and residents.

First, I developed …
