Formerly Used Defense Sites On Unalaska Island, Alaska: Mapping A Legacy Of Environmental Pollution, Jennifer Schmidt

ISER Articles

Unalaska Island, Alaska, served as a US military base during World War II. The military installed bases on Unalaska and nearby islands, many of which were built adjacent to Unangan communities. The military used toxic compounds in its operations and left a legacy of pollution that may pose health risks to residents and local wildlife. The goals of this study were to identify hotspots of contamination remaining at Unalaska formerly used defense (FUD) sites, evaluate the risk posed by arsenic, and examine “no US Department of Defense action indicated” (NDAI) status determinations for FUD sites near communities. We compiled soil …

Discovery Of Strong 3-Nitro-2-Phenyl-2h-Chromene Analogues As Antitrypanosomal Agents And Inhibitors Of Trypanosoma Cruzi Glucokinase, Shane M. Carey, Destiny M. O’Neill, Garrett B. Conner, Julian Sherman, Ana Rodriguez, Edward L. D'Antonio

Natural Sciences Faculty Publications

Chagas disease is one of the world’s neglected tropical diseases, caused by the human pathogenic protozoan parasite Trypanosoma cruzi. There is currently a lack of effective and tolerable clinically available therapeutics to treat this life-threatening illness and the discovery of modern alternative options is an urgent matter. T. cruzi glucokinase (TcGlcK) is a potential drug target because its product, D-glucose-6-phosphate, serves as a key metabolite in the pentose phosphate pathway, glycolysis, and gluconeogenesis. In 2019, we identified a novel cluster of TcGlcK inhibitors that also exhibited anti-T. cruzi efficacy called the 3-nitro-2-phenyl-2H-chromene analogues. This was achieved by performing a target-based …

Habitat Suitability For Age-0 Lake Sturgeon In The Grand River, Benjamin D. Gunnett

Masters Theses

Lake sturgeon (Acipenser fulvescens) are a state-threatened species in Michigan and have become a focus for conservation. The lower Grand River is home to a remnant population of lake sturgeon between the 6th Street dam in downtown Grand Rapids and Lake Michigan. There has been limited research on age-0 lake sturgeon habitat use in low-gradient and more turbid rivers. To address this deficit, we developed a Habitat Suitability Index (HSI) for age-0 lake sturgeon based on prior literature in the Great Lakes. A HSI combines parameters representing in-stream habitat characteristics to score habitat suitability on a scale of 0-1, 0 …

Relying on my own lived experience as a Lingít learner and educator, as well as interviews and conversations with Lingít community members, we discuss how relationality supports the larger goal of Lingít language and cultural revitalization. Specifically we talk about the role of women within the language movement, and what approaches can best …

If You Choose Not To Decide... Alaska’S Budgeting Process In 2023, Glenn Wright

Faculty, Staff, and Students

Alaska in 2023 is experiencing the first results of the new election system—the top-four all-party primary and Ranked Choice Voting. So far, that system seems to be generating results consistent with what advocates expected; a more moderate and collegial policy-making environment, and possibly even more sensible budgetary policy. This, coupled with relatively strong (though declining) oil prices, and abundant sovereign wealth led to a relatively low-drama, low-conflict budgeting process in spring 2023, as well as relatively moderate budgeting outcomes.

Chitosan-Based Hydrogels In Drug Delivery, Salma A. Fereig, Mona Mohamed Ahmed Abdelmottaleb

Pharmacy

Hydrogels are three-dimensional cross-linked hydrophilic polymers that are able to absorb large quantities of water and swell. They have various properties like biocompatibility, low toxicity, and mostly biodegradability, which make them attractive for drug delivery applications. Chitosan hydrogels are especially attractive due to the inherent activities of the chitosan itself like the antibacterial, anti-inflammatory, and tissue regeneration enhancement capacity. Therefore, chitosan hydrogels have been proposed for the delivery of various drugs, genes, cytokines, and stem cells via various routes of administration for the treatment of various diseases as well as different forms of degeneration.

Gucy2c Signaling Limits Dopaminergic Neuron Vulnerability To Toxic Insults, Lara Cheslow, Matthew Byrne, Jessica Kopenhaver, Lorraine Iacovitti, Richard Smeyne, Adam Snook, Scott Waldman

Farber Institute for Neuroscience Faculty Papers

Mitochondrial dysfunction and reactive oxygen species (ROS) accumulation within the substantia nigra pars compacta (SNpc) are central drivers of dopaminergic (DA) neuron death in Parkinson's disease (PD). Guanylyl cyclases and their second messenger cyclic (c)GMP support mitochondrial function, protecting against ROS and promoting cell survival in several tissues. However, the role of the guanylyl cyclase-cGMP axis in defining the vulnerability of DA neurons in the SNpc in PD remains unclear, in part due to the challenge of manipulating cGMP levels selectively in midbrain DA neurons. In that context, guanylyl cyclase C (GUCY2C), a receptor primarily expressed by intestinal epithelial cells, …

A Critical Review Of Sociological Research On Sexual Pleasure, Hannah Regan

Faculty Scholarship

Sociologists of sexuality often invoke the theme of pleasure, but it is not always clear what scholars believe the implications and importance of pleasure are. To this end, this paper reviews the existing literature on sexual pleasure, specifically within the field of sociology, to demonstrate what questions about sexual pleasure are (and are not) currently being asked. Through a systematic literature review, I demonstrate that scholars often lack a justification for why pleasure is important. I also connect themes between the kind of questions being asked about pleasure and the justifications attached to these studies, relating to risk mitigation, relationship …

Spatial Distribution Of Wildfire Threat In The Far North: Exposure Assessment In Boreal Communities, Jennifer Schmidt

ISER Articles

Increased wildfire activity has raised concerns among communities about how to assess and prepare for this threat. There is a need for wildfire hazard assessment approaches that capture local variability to inform decisions, produce results understood by the public, and are updatable in a timely manner. We modified an existing approach to assess decadal wildfire hazards based primarily on ember dispersal and wildfire proximity, referencing landscape changes from 1984 through 2014. Our modifications created a categorical flammability hazard scheme, rather than dichotomous, and integrated wildfire exposure results across spatial scales. We used remote sensed land cover from four historical decadal …

Increasing Multi-Hazard Climate Risk And Financial And Health Impacts On Northern Homeowners, Jennifer Schmidt

ISER Articles

Currently, more than half of the world’s human population lives in urban areas, which are increasingly affected by climate hazards. Little is known about how multi-hazard environments affect people, especially those living in urban areas in northern latitudes. This study surveyed homeowners in Anchorage and Fairbanks, USA, Alaska’s largest urban centers, to measure individual risk perceptions, mitigation response, and damages related to wildfire, surface ice hazards, and permafrost thaw. Up to one third of residents reported being affected by all three hazards, with surface ice hazards being the most widely distributed, related to an estimated $25 million in annual damages. …

Perceptions Of Patient-Healthcare Provider Relationships In The Management Of Type 2 Diabetes, Desiree D. Lacey

Walden Dissertations and Doctoral Studies

The patient-healthcare provider relationship (PPR) is the foundation of clinical care: it is established as a human relationship and has a profound effect on health outcomes. Though PPR has been studied in multiple health domains, there is very little on its role in managing Type 2 diabetes mellitus (T2DM). The purpose of this phenomenological qualitative research study was to better understand the challenges faced by healthcare providers (HCP) and T2DM patients within the clinical PPR for diabetes selfmanagement. The health belief model served as the theoretical framework and the diabetes self-management education program as the conceptual framework. Participants were recruited …

Socioeconomic Disparity Level And Telehealth Utilization Among Outpatient Healthcare Providers In California, Brittney Goodgame

Walden Dissertations and Doctoral Studies

The recent expansion of telehealth in the United States has created an opportunity for increased access to care for all patients, especially those with historically limited access. Grounded in Bronfenbrenner’s ecological systems theory, logistic regression analysis was used to determine if there is an association between community socioeconomic disparity level and telehealth utilization by healthcare providers. Secondary datasets were obtained through an independent insurance brokerage based in California. They contained claim level detail of patient visits conducted with outpatient healthcare providers in California. A random sample of 1,000 cases from the dataset were used for the completion of the study. …
