Gold Nanorod-Mediated Photothermolysis Induces Apoptosis To Macrophages Via Damage Of Mitochondria, Ling Tong, Ji-Xin Cheng

Birck Poster Sessions

Alterations in macrophage functions contribute to a variety of autoimmune and inflammatory diseases. Diagnosis and eradication of activated macrophages is becoming a valid pharmaceutical target. In this work, gold nanorods conjugated with arginine-rich peptides were applied as theragonosis agents to detect activated macrophages via two-photon luminescence (TPL) and subsequent eradicate through optical hyperthermia. Functionalized gold nanorods could be selectively internalized by activated macrophages in live animals 0.5 h after intraperitoneal (i.p.) injection. Apoptosis of macrophage was induced under proper irradiation conditions to reduce secondary inflammation, through mitochondria-dependent pathway.

M.D. Snodgrass: The Founder Of The Alaska State Fair, Talis James Colberg

Arctic and Northern Studies

This dissertation presents the life of M.D. Snodgrass as an example of how the Alaskan frontier transformed an unremarkable middle aged migrant into a socially prominent civic leader. The life of M.D. Snodgrass exemplifies how American frontier society provides ordinary people with exceptional opportunities to flourish and prosper. One of the end results of Snodgrass's taking advantage of Alaskan frontier opportunity was the Alaska State Fair. The dissertation divides the life of Snodgrass into four phases with the following findings: (1) The first thirty-one years of Snodgrass's life was spent outside of Alaska. His early life in Kansas demonstrates: the …

The Effects Of Perchlorate Exposure On A Model Vertebrate Species: The Threespine Stickleback, Richard R. Bernhardt

Biological Sciences

Few studies have examined the effects of chronic perchlorate exposure during multiple stages of development, and fewer still have analyzed the effects of perchlorate over multiple generations. Perchlorate exposure is known to cause thyrocyte hypertrophy (suggesting glandular stimulation), interference with thyroid hormone synthesis, and ultimately altered levels of circulating thyroid hormones, but whether these effects represent adaptive mechanisms or actual impairment is often debated within the scientific community. My research attempts to clarify whether exposure to environmentally relevant concentrations of perchlorate cause impairment at the organismal level. I examine ecologically significant endpoints to provide an indication if a contaminated population …

The Effects Of Climate Change On The Population Dynamics Of Trumpeter Swans, Joshua H. Schmidt

Biological Sciences

Survey data for trumpeter swans were collected throughout Alaska since 1968, but due to design difficulties and past analytical limitations, previous analyses were limited to simple summary statistics. The main purpose of my work was to rigorously analyze these data using advanced methods and determine rates of population change, the effects of environmental change on habitat use, and the influences of habitat features on habitat occupancy. I estimated that the adult population grew at a rate of 5.9% (95% credible interval = 5.2% to 6.6%) and production of cygnets increased at 5.3% (95% credible interval = 2.2% to 8.0%) annually. …

Distribution Of White Spruce In Alaska. An Open Access Prediction Surface From Climatic And Bioclimatic Parameters Using Esri Grid Formats., Falk Huettmann

Faculty

This open access data set contains a spatially gridded distribution of White Spruce in Alaska (ESRI GRID format), predicted from climatic and bioclimatic parameters (temperature, precipitation, elevation, and aspect). A species distribution model, developed by Bettina Ohse, was used to determine the ecological niche of the species based on the environmental variables. The model was developed within TreeNet, a classification and regression tree software. The ecological niche was then projected into geographical space, resulting in a predictive map of the species distribution in Alaska (4km resolution, tested accuracy of c. 95 %). We used ArcGIS 9.2. Data sources were freely …

Indigenous Emotional Economies In Alaska: Surviving Youth In The Village, Stacy Michelle Rasmus

Anthropology

According to the Status of Alaska Natives Report 2004 produced by the Institute of Social and Economic Research, University of Alaska Anchorage, Native youth in rural Alaska experience significant mental health disparity. Suicide rates for Alaska Native youth are the highest in the nation, and substance abuse, social misconduct and teenage pregnancy rates are also much higher among the rural, indigenous population in Alaska. These disparate rates have caused many to ask; what is going on with the youth in the villages today? This dissertation reports on research conducted to help answer that question, and identify local intervention strategies for …

Molecular Identification And Analysis Of Treponematosis (Syphilis, Bejel, Yaws, Or Pinta) In Ancient Mummified Remains From Northern Chile And Southern Peru, Michelle Kaye

Anthropology

The sequencing of Treponema pallidum subsp. pallidum, the bacterium that causes syphilis, and the identification of a family of 12 genes with sequence similarity that allows scientists to distinguish between treponemal subtypes has opened up a new line of inquiry for biological anthropologists. This research contributes genetic evidence of pre-contact treponematosis in the Americas; by combining osteological and molecular evidence with data on environment and cultural practices, it also furthers our knowledge of human-pathogen interaction. This research assessed the presence of treponematosis, a bacterial spirochete, in the DNA of skeletal and mummified human remains from northern Chilean cemeteries dating from …

Late-Pleistocene Syngenetic Permafrost In The Crrel Permafrost Tunnel, Fox, Alaska, M.Z. Kanevskiy, H.M. French, Y.L. Shur

Cold Regions Research and Engineering Laboratory (CRREL)

Late-Pleistocene syngenetic permafrost exposed in the walls and ceiling of the CRREL permafrost tunnel consists of ice-and organic-rich silty sediments penetrated by ice wedges. Evidence of long-continued syngenetic freezing under cold-climate conditions includes the dominance of lenticular and micro-lenticular cryostructures throughout the walls, ice veins and wedges at many levels, the presence of undecomposed rootlets, and organic-rich layers that reflect the former positions of the ground surface. Fluvio-thermal modifications are indicated by bodies ofthermokarst-cave ('pool') ice, by soil and ice pseudomorphs, and by reticulate-chaotic cryostructures associated with freezing ofsaturated sediments trapped in underground channels.

Cultivating Sustainability Through Participatory Action Research: Place -Based Education And Community Food Systems In Interior Alaska, Laura R. Henry-Stone

Indigenous Studies

As the environmental movement grows into a broader sustainability revolution, we must move beyond the traditional scope of environmental education to address social-ecological challenges through integrated education for sustainability. This research explores how place-based education can promote sustainability of a community food system in which feedbacks between production and consumption are integrated within a biocultural region. Through participatory action research, the project develops and demonstrates pedagogical components of sustainability that are applicable to formal and non-formal educational contexts. In this pedagogy, the purpose of sustainability education is to foster a community culture that will promote the emergence of sustainability in …

Applied Range Ecology Of Reindeer (Rangifer Tarandus Tarandus) On The Seward Peninsula, Alaska, Gregory Lawrence Finstad

Plant, Animal and Soil Sciences

Linking variation of the environment to animal production is key to successful range management. Ecological site descriptions (ESDs) are landscape units used by land managers for the grazing management of domestic reindeer ( Rangifer tarandus tarandus) on the Seward Peninsula, Alaska. This study investigated the appropriateness of using ESDs for the grazing management of reindeer and explored the use of alternate units to link landscape variation to animal production. ESD composition of reindeer ranges varied across the Seward Peninsula, but there was no relationship to either animal production, estimated by June calf weight and cow/calf ratios, or reindeer serum and …

Lingitx Haa Sateeyi, We Who Are Tlingit: Contemporary Tlingit Identity And The Ancestral Relationship To The Landscape, Vivian F. Martindale

Theses (Unassigned)

Divergent views on the Tlingit ancestral relationship to the landscape of Southeast Alaska often leads to conflicts between Western-orientated government agencies, public entities, and the Tlingit people themselves. To better understand this subject, I collected nine personal narratives from research participants from within the Tlingit nation. The narratives provide insight into the dynamics at the intersection of conflicting worldviews, and the role this plays in shaping contemporary Tlingit identity. The results of exploring these diverging worldviews has illuminated three factors influencing contemporary Tlingit identity: the loss and struggle with maintaining the Lingit language, implementation of subsistence regulations and resultant conflicts, …

The Development And Application Of Stable Oxygen And Hydrogen Isotope Analyses Of Chironomidae (Diptera) As Indicators Of Past Environmental Change, Yiming Wang

Geosciences

Environmental change continues to be of increasing interest to scientists in all disciplines, and there is a paramount need to gain a comprehensive understanding of the impacts of environmental change in the past to better predict the future. A challenge associated with interpreting past change is a lack of reliable proxies to infer past environmental conditions preserved in the fossil record. My research has been dedicated to developing techniques associated with analyzing the stable oxygen and hydrogen isotopic composition (delta18O and deltaD) of subfossil chironomid (Chironomidea: Diptera) headcapsules (primarily composed of chitin) preserved in lake sediments as a new proxy …

Local Perceptions And Regional Climate Trends On The Central Plateau Of Burkina Faso, C.T. West, C. Roncoli, F. Ouattara

ISER Reports

Due to devastating droughts in the 1970s and 1980s, climatic and environmental change in the West African Sahel has attracted a great deal of scientific research. While many of these studies documented a long-term trend of declining rainfall, analyses conducted in the last few years suggest that a ‘recovery’ is underway. Drawing on ethnographic interviews, focus groups, and participant observation in two Provinces of the Central Plateau of Burkina Faso, we elicited local perspectives on these rainfall trends from the people who are most directly affected, namely local farmers. Fieldwork revealed that farmers in the research sites perceive that both …

Foraging Ecology And Nutritional Stress Of Tufted Puffins (Fratercula Cirrhata) Inferred From Stable Isotopes, Fatty Acid Signatures, And Field Endocrinology, Cory T. Williams

Marine Biology

Prey availability has a major impact on the reproductive output of seabirds, yet information on seabird diets throughout the breeding season is often lacking. Although reduced prey availability is known to affect the growth and survival of nestling seabirds, few studies have demonstrated similar effects on indices of adult body condition. I used stable isotopes and fatty acid (FA) signatures to investigate seasonal and age-related variation in the foraging niches of tufted puffins (Fratercula cirrhata). I conducted captive feeding experiments to determine whether inferences based on these techniques are affected by moderate food restriction during growth. I also examined how …

Perspectives On The Dynamic Human-Walrus Relationship, Martin D. Robards

Biological Sciences

Changes in sea ice conditions have direct bearing on ice-associated species such as Pacific walrus (Odobenus rosmarus divergens), which are an important component of subsistence for Alaska Native communities in the Bering Sea. I explore the relationship between walrus, sea ice, and Alaska Native subsistence at Diomede, Gambell, and Savoonga between 1952 and 2004 to better understand walrus ecology and subsistence under different climatic regimes. I then consider how the inability to reliably and regularly count walrus and other ice-associated pinnipeds in this dynamic environment challenges effective management of walrus and subsistence under the Marine Mammal Protection Act (MMPA). However, …

Site Fidelity: Definition, Measurement And Implications For Population Structure Using Mark-Recapture, Genetic, And Comparative Data In The Hooded, Red-Breasted, And Common Merganser, John Maunsel Pearce

Biological Sciences

For species that return each year to the same breeding or nonbreeding area, subsequent biological assumptions have included population genetic structure, demographic independence, and possible irreversible extirpation of a site-faithful group due to low immigration. Little is known about patterns of site fidelity, population structure, and migratory patterns of the three species of mergansers that breed and winter in North America: the Hooded Merganser (Lophodytes cucullatus), the Red-breasted Merganser (Mergus serrator ) and Common Merganser (M. merganser). The primary objective of this study was not only to infer general levels of site fidelity with different data types (mark-recapture and genetic), …
