An Evaluation Of The Registration And Use Prospects For Four Candidate Toxicants For Controlling Invasive Mongooses (Herpestes Javanicus Auropunctatus), Emily W. Ruell, Chris N. Niebuhr, Robert T. Sugihara, Shane R. Siers

United States Department of Agriculture Wildlife Services: Staff Publications

The eradication or control of invasive small Indian mongooses from islands likely requires toxic baiting when removal by trapping proves insufficient. The one toxic bait currently registered for mongooses in the United States has relatively low palatability and efficacy for mongooses. Developing and registering a new pesticide can be very expensive, while funding for developing toxicants for mongooses is limited. Once registered, use of a toxic bait may be hindered by other factors, such as public opposition to an inhumane toxicant, poorer efficacy than expected, or if the toxic bait is difficult for applicators to apply or store. Therefore, we …

Planetary geology and planetary exploration complement each other:planetary exploration provides an important research basis for the development of planetary geology, and the new discoveries of …

Research On Risks And Countermeasures Of "Cities Besieged By Waste" In China—An Empirical Analysis Based On Diis, Chen An, Chen Jingrui, Cui Jing, Fan Chao, Han Wei

Bulletin of Chinese Academy of Sciences (Chinese Version)

Nowadays, China's fast-growing cities are suffering from the problem of "Cities Besieged by Waste". The true portrayal of China today is people live in cities, while the cities are trapped in waste. China is still in this dilemma that a lot of garbage is difficult to memorial archway, clear, dispose, and manage, although local governments have promulgated corresponding policies in recent years. Tragedies caused by "Cities Besieged by Waste" are still everywhere. The risk situation and countermeasures of "Cities Besieged by Waste" should not be ignored, but should be focused on instead. Based on the DIIS (Data-Information-Intelligence-Solution) framework, this study …

Global Biodiversity And Conservation Along The Belt And Road Initiative, Meng Honghu, Gao Xiaoyang

Bulletin of Chinese Academy of Sciences (Chinese Version)

Biodiversity is essential to human well-being, enhancing many of nature's benefits, and playing an important role in the survival and development of the material basis to people. Therefore, sustainability of biodiversity is crucial to human health and life. However, human activities and climate changes are exerting a far-reaching influence on biodiversity, which are even driving the sixth mass extinction in Earth's history. Extraordinary rates of biodiversity loss, coupled with rising human population and consumption rates with the ongoing development of human societies and economies, are threatening the sustainability of Earth's life support systems. While developing the economy, China is making …

The Bone Extracellular Matrix As An Ideal Milieu For Cancer Cell Metastases., Alexus D. Kolb, Karen M. Bussard

Department of Cancer Biology Faculty Papers

Bone is a preferential site for cancer metastases, including multiple myeloma, prostate, and breast cancers.The composition of bone, especially the extracellular matrix (ECM), make it an attractive site for cancer cell colonization and survival. The bone ECM is composed of living cells embedded within a matrix composed of both organic and inorganic components. Among the organic components, type I collagen provides the tensile strength of bone. Inorganic components, including hydroxyapatite crystals, are an integral component of bone and provide bone with its rigidity. Under normal circumstances, two of the main cell types in bone, the osteoblasts and osteoclasts, help to …

Growing On A Scar: Genetic Variation Of Achillea Millefolium Near Meeker, Colorado, Ace Spitzer

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Mining operations deposit high concentrations of heavy metals such as lead, cadmium, arsenic, and vanadium into the topsoil of an ecosystem. These toxic metals can affect plant health and behavior, causing local extinction and shifts in ecosystem dynamics. However, genetic analyses of some plants growing on toxic soil conditions indicate higher genetic diversity than would be expected in that environment. Determining the effects of soil pollution on plants is important to determine a species’ utility in conservation and restoration. This investigation compared the genetic diversity of western yarrow (Achillea millefolium, Asteraceae), growing near a mine with vanadium and …

Artemisinin: From Chinese Herbal Medicine To Modern Chemotherapy, Anthony Butler

HIMALAYA, the Journal of the Association for Nepal and Himalayan Studies

Malaria is a disease that has blighted humankind since early times. The first antimalarial treatment available to Europeans was the dried bark of the cinchona tree from Peru. The main problem in its use was adulteration by other material. The ‘active principle’ was first extracted in 1820 and named quinine. It was found to be a more powerful and reliable drug than cinchona bark. Once its chemical structure had been determined, it was possible to synthesize substances chemically related to quinine that were equally powerful but could be manufactured industrially. Mepacrine (atabrine) was amongst the most successful, but had adverse …

Challenging The Biomedical Notion Of ‘Active Substance’: The Botanical Plasticity Of Tibetan Medical Formulas, Herbert Schwabl, Jan M. A. Van Der Valk

HIMALAYA, the Journal of the Association for Nepal and Himalayan Studies

Sowa Rigpa (Tibetan medicine) has been practiced across vast regions of Central and South Asia for centuries. In this medical tradition, it is common practice to dynamically adapt the mainly herbal formulas according to the regional flora and local conditions, and to use local variants of ingredients. Consequently, one Tibetan ingredient name within a specific formula can signify a variety of therapeutically fitting botanical items, which appear quite different from the perspective of modern taxonomy. This has led many researchers to understand the botanical plasticity of Tibetan medical formulas as misidentifications. We develop an alternative approach, exploring the advantages of …

Conceptions Of Potency, Purity, And Synergy-By-Design: Toward Developing A Sowa Rigpa Medical Theory-Based Approach To Pharmaceutical Research, Tawni L. Tidwell, James H. Nettles

HIMALAYA, the Journal of the Association for Nepal and Himalayan Studies

Sowa Rigpa institutions and practitioners have growing interest in examining and legitimizing Sowa Rigpa formulas vis-à-vis pharmacological research methods, seeking scientific validation of what they view as ‘potency’ and ‘purity’ for their formulas. Likewise, the pharmacology researchers have demonstrated renewed interest in herbal medical traditions in mining for new drugs to address resistance, toxicity, and optimize what they view as ‘potency’ and ‘purity.’ However, differing conceptualizations emerge when the pharmacological drug discovery process is examined to determine what is being analyzed, how it is doing so, and what assumptions underlie such methods. Whether a formula is ‘active,’ ‘toxic’ or ‘effective’ …

Garuda 5 (Khyung Lnga): Ecologies Of Potency And The Poison-Medicine Spectrum Of Sowa Rigpa’S Renowned ‘Black Aconite’ Formula, Jan M. A. Van Der Valk

HIMALAYA, the Journal of the Association for Nepal and Himalayan Studies

This article focuses on ethnographic work conducted at the Men-Tsee-Khang (Dharamsala, India) on Garuda 5 (khyung lnga), a commonly prescribed Tibetan medical formula. This medicine’s efficacy as a painkiller and activity against infection and inflammation is largely due to a particularly powerful plant, known as ‘virulent poison’ (btsan dug) as well as ‘the great medicine’ (sman chen), and identified as a subset of Aconitum species. Its effects, however, are potentially dangerous or even deadly. How can these poisonous plants be used in medicine and, conversely, when does a medicine become a poison? How can ostensibly the same substance be both …

Potency By Name? ‘Medicine Buddha Plant’ And Other Herbs In The Japanese Scroll Of Equine Medicine (Ba’I Sōshi Emaki, 1267), Katja Triplett

HIMALAYA, the Journal of the Association for Nepal and Himalayan Studies

Buddhist ritual healing and medical therapies included care for domestic animals, such as the horse. In pre-modern Japan, equine medicine (ba’i 馬医) was not restricted to the treatment of military horses; it was also practiced in a religious context. The Scroll of Equine Medicine (Ba’i sōshi emaki 馬医草紙絵 巻, 1267) is an enigmatic picture scroll held by the Tokyo National Museum. It extends to more than six meters and contains images of ten divine figures related to the healing of horses, followed by seventeen pictures of plants, and a postscript emphasizing that the content of the scroll should be kept …

Subjective Well-Being In Two Himalayan Communities, Post Road Development, Michelle U. Grocke, Kimber Haddix Mckay, Thomas Foor

HIMALAYA, the Journal of the Association for Nepal and Himalayan Studies

Although the first road to ever be built into Humla, Nepal is still under construction, it has already spurred numerous sociocultural and economic changes, including an increased integration into the market economy, changing access to market-purchased foods, and new kinds of health-seeking behavior. This paper is part of a larger research project where we examined changing health and nutrition outcomes co-synchronous with the arrival of this road. In this paper, we focus on whether and how the road is affecting villagers’ subjective well-being (SWB). We studied this while living and working with people from two Humli villages, one that is …

Racial Reassignment Surgery And The Dissolution Of The Color Line: Afrofuturist Satire In George Schuyler’S Black No More And Jess Row’S Your Face In Mine, Christopher A. Varlack

Third Stone

Racial passing, during the antebellum period, was a way in which African-American peoples sought to escape the throes of slavery and the physical and psychological abuse associated with the plantation tradition. In time, racial passing became a way of obtaining the social, economic, and political opportunities denied people of color in the discriminatory and racially-biased United States. This study, however, examines a specific form of racial passing--that of racial reassignment surgery--as explored in George Schuyler’s Black No More and Jess Row’s Your Face in Mine as a way to test the theory that assimilation and miscegenation would one day resolve …

The Shape Of You: Music's Impact On Identity, Codi Yhap

Music Summer Fellows

Investigating the multiple functions of music, scholars from various fields have expressed that music can regulate moods and emotions while providing listeners a way to navigate their identity. Focusing primarily on the genre of rap, this research has placed the field of Music and Emotion in conversation with Hip-Hop studies. The field of Music and Emotion has thoroughly measured/examined listener thought processes, bodily response, and cultural influences when engaging with music. Despite the rise in scholarship addressing popular music and emotion, the field rarely includes popular music in its discussions unless, perhaps, the genre is jazz. Recognizing that there are …

Beyond The 3rs: Expanding The Use Of Human-Relevant Replacement Methods In Biomedical Research, Kathrin Herrmann, Francesca Pistollato, Martin L. Stephens

Biomedical Research and Alternative Methods Collection

This year marks the 60th anniversary of Russell and Burch’s pioneering book, The Principles of Humane Experimental Technique. Their 3Rs framework has helped to inspire humane and scientific progress in experimental technique. However, it is time to update its strategic application. The 21st century has already seen the development of promising, high-tech non-animal models, such as organs-on-a-chip and computational approaches that, in our view, will replace animals as the default option in biomedical experimentation. How fast this transition will take place will depend on the pace at which these new models are optimized to reflect the biology of humans, rather …

Synthesizing Conservation Motivations And Barriers: What Have We Learned From Qualitative Studies Of Farmers’ Behaviors In The United States?, Pranay Ranjan, Sarah P. Church, Kristin Floress, Linda S. Prokopy

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Since 2011, qualitative studies examining adoption of conservation practices and programs (CPPs) have burgeoned. This article presents a systematic review of all U.S.-based qualitative investigations into CPP adoption since 1996. We found three themes are discussed primarily as motivating adoption: farmer characteristics, environmental awareness, and trust in information sources. Four themes are discussed primarily as barriers to adoption: farm management, negative perceptions of a conservation practice, perceptions that adoption is a risk, and land tenure. Four themes were discussed as both motivations and barriers: economic factors, social norms, perceptions of government programs, and farm characteristics. Overall, we found farmers’ economic …

Iamhappy: Towards An Iot Knowledge-Based Cross-Domain Well-Being Recommendation System For Everyday Happiness, Amelia Gyrard, Amit Sheth

Kno.e.sis Publications

Nowadays, healthy lifestyle, fitness, and diet habits have become central applications in our daily life. Positive psychology such as well-being and happiness is the ultimate dream of everyday people’s feelings (even without being aware of it). Wearable devices are being increasingly employed to support well-being and fitness. Those devices produce physiological signals that are analyzed by machines to understand emotions and physical state. The Internetof Things (IoT) technology connects (wearable) devices to the Internet to easily access and process data, even using Web technologies (aka Web of Things).

We design IAMHAPPY, an innovative IoT-based well-being recommendation system to encourage every …

Network‐Based Feature Selection Reveals Substructures Of Gene Modules Responding To Salt Stress In Rice, Qian Du, Malachy Campbell, Huihui Yu, Kan Liu, Harkamal Walia, Qi Zhang, Chi Zhang

Center for Plant Science Innovation: Faculty Publications

Rice, an important food resource, is highly sensitive to salt stress, which is directly related to food security. Although many studies have identified physiological mechanisms that confer tolerance to the osmotic effects of salinity, the link between rice genotype and salt tolerance is not very clear yet. Association of gene co‐expression network and rice phenotypic data under stress has penitential to identify stress‐responsive genes, but there is no standard method to associate stress phenotype with gene co‐expression network. A novel method for integration of gene co‐expression network and stress phenotype data was developed to conduct a system analysis to link …

A Novel Rapamycin Analog Is Highly Selective For Mtorc1 In Vivo., Katherine H. Schreiber, Sebastian I. Arriola Apelo, Deyang Yu, Jacqueline A Brinkman, Michael C Velarde, Faizan A Syed, Chen-Yu Liao, Emma L. Baar, Kathryn A. Carbajal, Dawn S. Sherman, Denise Ortiz, Regina Brunauer, Shany E. Yang, Stelios T Tzannis, Brian K Kennedy, Dudley W Lamming

Natural Sciences and Mathematics | Student Professional Publications

Rapamycin, an inhibitor of mechanistic Target Of Rapamycin Complex 1 (mTORC1), extends lifespan and shows strong potential for the treatment of age-related diseases. However, rapamycin exerts metabolic and immunological side effects mediated by off-target inhibition of a second mTOR-containing complex, mTOR complex 2. Here, we report the identification of DL001, a FKBP12-dependent rapamycin analog 40x more selective for mTORC1 than rapamycin. DL001 inhibits mTORC1 in cell culture lines and in vivo in C57BL/6J mice, in which DL001 inhibits mTORC1 signaling without impairing glucose homeostasis and with substantially reduced or no side effects on lipid metabolism and the immune system. In …

How Characteristic Is The Species Characteristic Selection Scale?, Erica F. Stuber, Joseph J. Fontaine

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Aim: The importance of framing investigations of organism–environment relationships to interpret patterns at relevant spatial scales is increasingly recognized. However, most research related to environmental relationships is single‐scaled, implicitly or explicitly assuming that a “species characteristic selection scale” exists. We tested the premise that a single characteristic scale exists to understand species– environment relationships within species by asking (a) what are the characteristic scales of species’ relationships with environmental predictors, and (b) is within species, cross‐predictor consistency in characteristic scales a general phenomenon.

Mixing It Up: The Impact Of Episodic Introgression On The Evolution Of High-Latitude Mesocarnivores, Jocelyn P. Colella

Biology ETDs

At high latitudes, climatic oscillations have triggered repeated episodes of organismal divergence by geographically isolating populations. For terrestrial species, extended isolation in glacial refugia – ice-free regions that enable terrestrial species persistence through glacial maxima – is hypothesized to stimulate allopatric divergence. Alternatively, upon glacial recession, divergent populations expanded from independent glacial refugia and often contacted other diverging populations. In the absence of reproductive isolating mechanisms, this biogeographic process may trigger hybridization and ultimately, gene flow between divergent taxa. My dissertation research aims to understand how these episodic periods of isolation and contact have impacted the evolution of high latitude …

Microbial Analysis Of Surfactant-Associated Bacteria In The Sea Surface Microlayer And Remote Sensing Of Associated Slicks, Georgia Parks

HCNSO Student Theses and Dissertations

The sea-surface microlayer (SML) is the boundary layer at the air-sea interface where many biogeochemical processes occur. Many organisms (e.g., bacteria) produce surface active agents (surfactants) for life processes, which accumulate in the SML and dampen short gravity-capillary waves, resulting in sea surface slicks. Synthetic aperture radar (SAR) is capable of remotely sensing these features on the sea surface by measuring reflected backscatter from the ocean surface in microwaves. This study coordinates SAR overpasses with in situ SML and subsurface (SSW) microbial sample collection to guide subsequent analysis after 16s rRNA sequencing on the Illumina MiSeq. In April …
