Valorization of Xylan in Agroforestry Waste Streams.
Harrison Appiah
Microwave-assisted deep eutectic solvent and gamma-valerolactone metallic chloride catalyzed conversion of xylan to furfural were investigated using a 2x3 factorial experimental design at two levels of percent microwave power, reaction time, and catalyst concentration. The levels of each factor studied were (20%, 60% microwave power, 2, 4 minutes, and 10, 20mg) respectively. The effect of three metallic chloride catalysts (LiCl, FeCl3.6H20, CuCl2) on the conversion of xylan to furfural was also investigated. The gamma-valerolactone-ferric chloride sent system exhibited the highest mean yield of furfural (56.50%). The next highest furfural yield of …
Climatic Drivers Of Growth In Mixed Conifer Forests Of The Sierra Nevada For Different Tree Sizes And Thinning Treatments, Andrew M. Hirsch
Climatic Drivers Of Growth In Mixed Conifer Forests Of The Sierra Nevada For Different Tree Sizes And Thinning Treatments, Andrew M. Hirsch
Graduate Theses, Dissertations, and Problem Reports
The Mediterranean region of northern California is projected to get increasingly warmer under all Intergovernmental Panel on Climate Change (IPCC) emission scenarios, with future precipitation projections not showing much of a trend. This poses a problem to the already dry summers that are experienced in the Mediterranean region of California. If precipitation does not increase alongside temperatures, the dry seasons will likely only get drier. The use of dendroclimatology to assess how mixed conifer species in the Sierra Nevada responded to past climate is a key resource that can be used to infer how trees may respond to a future …
Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler
Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler
Graduate Theses, Dissertations, and Problem Reports
Soils in the Monongahela National Forest (MNF) are acidic due to sandstone parent material, acid deposition, uptake of base cations by vegetation, and release of organic acids by organic matter (OM) decomposition. Increases in soil acidity have caused declines in forest health and changed species composition and nutrient status. Liming can neutralize soil acidity, but no large-scale liming projects have been done on acid forest soils in the USA. In anticipation of acquiring funding for a proposed liming project in the MNF, in 2007 and 2009 10 sites were selected to sample and analyze soils before lime was applied. In …
Determining The Effects Of Imidacloprid On Non-Target Soil Organisms In Hemlock Stands, Braley Burke
Determining The Effects Of Imidacloprid On Non-Target Soil Organisms In Hemlock Stands, Braley Burke
Graduate Theses, Dissertations, and Problem Reports
The hemlock woolly adelgid (HWA), Adelges tsugae Annand (Hemiptera: Adelgidae), is an invasive insect that is causing mortality of eastern hemlock trees, Tsuga canadensis, and Carolina hemlock trees, Tsuga caroliniana, across the eastern United States. To protect these ecologically important tree species, a neonicotinoid insecticide, imidacloprid, is commonly used. Imidacloprid is an effective treatment and can remain effective against HWA for four to six years but long-term (≥ one year after application) non-target effects of imidacloprid on forest ecosystems are not well-studied. This study examined terrestrial non-target effects of imidacloprid in hemlock stands with different treatment histories to …
Mitochondrial Aspects Of Neuronal Pathology In Triple-Transgenic Alzheimer’S Disease Mice, John Zachary Cavendish
Mitochondrial Aspects Of Neuronal Pathology In Triple-Transgenic Alzheimer’S Disease Mice, John Zachary Cavendish
Graduate Theses, Dissertations, and Problem Reports
Alzheimer’s disease (AD) is a fatal, progressive neurodegenerative disease afflicting millions of people in the United States alone and is the only one of the top leading causes of morbidity and mortality with no effective disease-modifying therapies. It is the most common form of dementia, affecting one in three people over the age of 85. While the hallmarks of the disease include accumulation of beta-amyloid-based extracellular plaques and hyperphosphorylated tau-based intracellular neurofibrillary tangles, treatment strategies centered on removing or mitigating these components of AD have all failed in humans. Mitochondrial dysfunction has been increasingly recognized as an early and consistent …
Biomechanically Inspired Assistive Technology To Restore Movement Of The Upper Limbs After Stroke, Ariel Thomas
Biomechanically Inspired Assistive Technology To Restore Movement Of The Upper Limbs After Stroke, Ariel Thomas
Graduate Theses, Dissertations, and Problem Reports
A stroke often damages the neural structures responsible for movement. Stroke is a heterogeneous disease, affecting each survivor differently. There are common motor features of a stroke, but even these features vary across time as an individual proceeds through different stages of recovery. The different ways in which stroke motor impairment can present itself are often overlooked, but these differences are fundamental to the understanding of the disease and its recovery. When motor assessments are capable of acquiring information necessary to parse out a detailed profile of each stroke case, this will lead to an improved neuromechanical understanding of the …
Improving Microbial Safety Of Locally Grown Produce In West Virginia Area, Kawang Li
Improving Microbial Safety Of Locally Grown Produce In West Virginia Area, Kawang Li
Graduate Theses, Dissertations, and Problem Reports
There is a growing concern regarding the microbial safety of farmers’ markets as fresh produce consumption in the United States is gaining popularity. The CDC reported 46% of foodborne illnesses are related to fresh produce. Consuming fresh produce raw removes a processing step, increasing the risk of cross-contamination, leading to illness. However, this risk can be mitigated by washing produce with antimicrobial solutions during post-harvest processes. To reduce the microbial load on fresh produce, the triple-wash process, where the produce is rinsed with water twice and lastly an antimicrobial solution (WWA). WWA is recommended by the WVU Extension Service Small …
The Origin Of Novel Trait Inferred From Transcriptomic Analysis And A Targeted Gene Approach In The Beetle Horns., Naureen Fatima
The Origin Of Novel Trait Inferred From Transcriptomic Analysis And A Targeted Gene Approach In The Beetle Horns., Naureen Fatima
Graduate Theses, Dissertations, and Problem Reports
The origin of the evolutionary new trait (evolutionary novelty) and its subsequent evolution is of great interest for biologists in various fields, and beetle horns have been used to address this fundamental biological question. Previous studies on one of the horned beetle species, Onthophagus taurus, that utilized comparative gene expression analyses, suggested legs to be a strong candidate of the origin of horns. At the same time, their horns are secondary sexual traits whose development is regulated by the same gene (doublesex) as genitalia, which also originates from paired appendages such as legs. However, little is known …

Tree Species Influence On Microbial Functional Gene Abundance And N Cycling In Riparian Soil, Elizabeth Matejczyk
Tree Species Influence On Microbial Functional Gene Abundance And N Cycling In Riparian Soil, Elizabeth Matejczyk
Graduate Theses, Dissertations, and Problem Reports
Little is known about how above-ground vegetation may differentially influence the below-ground microbial community structure, abundance, and function. Abundance of soil microbial N cycling genes responsible for nitrification (amoA), denitrification (nirK and nirS), and nitrous oxide reduction (nosZ) may vary with tree species and increasing N availability, and these variables may be used to predict production of NO3- and N2O from soil. Variability of nitrification and denitrification rates have also been linked to tree mycorrhizal associations, with soil beneath tree species associated with arbuscular mycorrhizal (AM) exhibiting greater denitrification rates …

Targeting The Cerebrovasculature In Sepsis: A Focus On The Brain Microvascular Endothelium, Divine C. Nwafor
Targeting The Cerebrovasculature In Sepsis: A Focus On The Brain Microvascular Endothelium, Divine C. Nwafor
Graduate Theses, Dissertations, and Problem Reports
The blood-brain barrier (BBB) is a critical interface between the systemic circulation and the brain. It is a specialized multicellular unit composed of brain microvascular endothelial cells (BMECs), pericytes, a basement membrane, and astrocytic end foot processes. BMECs are a principal component of the BBB that provide the structural framework needed for the stringent transport of molecules into the brain. BMEC dysfunction permits the trafficking of neurotoxins from systemic circulation into the brain, which ultimately exacerbates BBB dysfunction and neuroinflammation. Studies have shown that BBB dysfunction is a key determinant of cognitive decline in sepsis. However, there are critical knowledge …
Meeting The Mental Health Needs Of Student-Athletes: A Descriptive Study Of Practitioners And Their Perspectives, William C. Way Iii
Meeting The Mental Health Needs Of Student-Athletes: A Descriptive Study Of Practitioners And Their Perspectives, William C. Way Iii
Graduate Theses, Dissertations, and Problem Reports
Efforts are being made to promote mental health awareness and destigmatize help-seeking behavior among student-athletes (e.g., Kern et al., 2017). The availability and visibility of practitioners with specialized training in sport psychology can facilitate these efforts (e.g., Flowers, 2007; Carr, 2007; McDuff et al., 2005). However, some student-athletes have observed that the clinical sport psychology (CSP) practitioners who are available to them are being stretched thin (Way et al., 2020). In the context of collegiate mental health more broadly, many campus counseling centers are struggling to meet the demand for clinical services (e.g., Kafka, 2019). Research on the experiences and …
Effects Of Biofertilizer On Soil Nutrient Cycling And The Productivity Of Bioproduct Crops In Marginal Soils, Kieran B. Liseski
Effects Of Biofertilizer On Soil Nutrient Cycling And The Productivity Of Bioproduct Crops In Marginal Soils, Kieran B. Liseski
Graduate Theses, Dissertations, and Problem Reports
Recently there has been increased interest in the use of marginal lands in order to grow bioproduct crops. Utilizing marginal lands to grow bioproduct crops such as Miscanthus x giganteus and Panicum virgatum could not only improve soil quality and minimize negative environmental impacts on the surrounding ecosystems but could also offer economic benefits to growers in rural areas. Because marginal soils tend to reduce crop yields compared to prime farmlands even when growing bioproduct crops, which tend to be more robust than traditional food crops, augmenting the soil with biofertilizers (i.e., the direct addition of viable microbial cells) could …
Mechanisms And Therapeutic Interventions For Breast Cancer-Induced Fatigue And Mitochondrial Dysfunction, David Andrew Stanton
Mechanisms And Therapeutic Interventions For Breast Cancer-Induced Fatigue And Mitochondrial Dysfunction, David Andrew Stanton
Graduate Theses, Dissertations, and Problem Reports
According to the latest statistics from the National Cancer Institute (NCI), about 1 in 8 U.S. women (~13%) will develop invasive breast cancer over the course of their lifetime. This translates to an estimated 268,600 new cases of breast cancer for the year 2019, and these diagnoses will collectively make up 15% of all new cancer cases across all cancer types. The majority of these women will experience the often-debilitating symptom of breast cancer-induced fatigue. these patients often have difficulty performing normal activities of daily living, have decreased tolerance to traditional tumor-directed therapies, and have higher rates of cancer recurrence. …

Initial And Advanced Stages Of Microbiota Establishment Within The Tsetse Fly, Miguel Eduardo Medina Munoz
Graduate Theses, Dissertations, and Problem Reports
Symbiosis is a long-term physical association between two or more species, although little is known regarding its evolutionary origins, particularly at the genetic level. Tsetse flies are the vector of African trypanosomes, causative agents of Human and Animal African Trypanosomiases. Tsetse provide an ideal model for studying initial and advanced stages of symbiosis. Tsetse have a simple digestive tract microbiota primarily consisting of two bacteria; the ancient mutualist Wigglesworthia glossinidia and the recently acquired Sodalis glossinidius. This work presents a chronological study in evolutionary terms of the history of a microbial-insect association. First, I present concepts on symbiosis and …
Manipulating The Perineuronal Net In The Deep Cerebellar Nucleus, Deidre E. O'Dell
Manipulating The Perineuronal Net In The Deep Cerebellar Nucleus, Deidre E. O'Dell
Graduate Theses, Dissertations, and Problem Reports
Perineuronal nets (PNN) are a type of specialized extracellular matrix in the central nervous system. The PNN forms during postnatal development but the ontogeny of the PNN has yet to be elucidated. Studying the PNN in the rat brain may allow us to further understand the PNN’s role in development, learning, and memory. The PNN is fully developed in the deep cerebellar nuclei (DCN) of rats by post-natal day 18. By using enzymatic digestion of the PNN with chondroitinase ABC (ChABC), we studied how digestion of the PNN affects cerebellar-dependent eyeblink conditioning (EBC) and performed electrophysiological recordings from DCN neurons. …

Graduate Theses, Dissertations, and Problem Reports
Photoreceptors are specialized neuroepithelial cells which are optimized for efficient capture of light and initiation of visual transduction. These cells have several compartments which are very important for proper visual function and segregation of cellular processes, including the outer segment (OS), inner segment (IS), nucleus, and synapse. The IS houses all of the cellular organelles and biosynthetic molecular machinery the cell requires and is the site of protein synthesis. The light-sensing OS is a highly modified, primary cilium, which contains many stacks of double membranous discs which house proteins required for formation and maintenance of OS structure, as well as …

Modern shallow brine environments contain an abundance of microorganisms. Microorganisms, mineral crystals, and air bubbles can be trapped with those brines in primary fluid inclusions in bedded halite as it grows in shallow saline surface waters. Primary fluid inclusions and their contents can be preserved, unaltered, for millions of years.
The ~830 million-year-old Browne Formation of central Australia contains intervals of bedded halite with unaltered primary fluid inclusions. Intervals of bedded halite were sampled in the Empress 1A core from ~1480 m – 1520 m depths. Here, I used petrography to describe suspect microorganisms and organic compounds that were trapped …
Nuclear Aurora-A Kinase-Induced Hypoxia Signaling Drives Dissemination And Metastasis In Breast Cancer., Kristina Marinak Whately
Nuclear Aurora-A Kinase-Induced Hypoxia Signaling Drives Dissemination And Metastasis In Breast Cancer., Kristina Marinak Whately
Graduate Theses, Dissertations, and Problem Reports
Metastatic breast cancer causes the vast majority of cancer-associated deaths, especially in triple negative breast cancers (TNBC). TNBC is still poorly understood and has no effective treatment. Here we reveal that presence of Aurora-A Kinase (AURKA) in the nucleus and metastatic dissemination are molecularly connected through HIF1 (Hypoxia induced factor-1) signaling. The nuclear AURKA in the complex with constitutively expressed HIF-1β subunit activates transcription of “hypoxia induced genes” under normoxic conditions (the phenomenon called pseudohypoxia) without upregulation of oxygen-sensitive HIF-1α subunit. We uncover that AURKA preferentially binds to and phosphorylates HIF-1β, and co-localizes with HIF complex on DNA. The mass …

Effects Of 4-Methylcyclohexanemethanol On Stress Response Pathway Regulators, In Saccharomyces Cerevisiae, Suk Lan Ser
Graduate Theses, Dissertations, and Problem Reports
Hydrotropes are small molecules capable of inducing liquid-liquid phase separation by altering the solubility and conformation states of organic compounds that are increasingly becoming important in organizing chemical reactions and regulating complexes. They prevent protein aggregation causing these proteins to form condensates. Mediator, a highly conserved multi-subunit complex, plays an important role in transcription. Med15, a subunit found within the tail domain of the Mediator complex, works with stress-induced transcription factors and is regulated by many kinases, including CDKs and the AMP kinase, Snf1. Living cells respond by changing molecular and cellular pathways when they are exposed to stressful conditions. …

Insect Community Associated With Black Cherry (Prunus Serotina) In The Allegheny National Forest, Craig James Larcenaire
Graduate Theses, Dissertations, and Problem Reports
Black cherry (Prunus serotina Ehrh.) is valuable species managed for its economic and ecologic benefits. This species grows best in the environment of the Allegheny Plateau region in northwestern Pennsylvania. Land managers on the Allegheny National Forest (ANF) have been managing black cherry for a variety of goals and purposes. Over the last few decades, the land managers have noticed a decline in the natural regeneration of black cherry in the forest. Because the black cherry flowers are self-incompatible and require animal pollinators to transfer the pollen from one tree to another one hypothesis for this decline could be …

Biocompatible And Multifunctional Trityl Spin Probes For Electron Paramagnetic Resonance Spectroscopy, Teresa D. Gluth
Graduate Theses, Dissertations, and Problem Reports
The primary objective of my thesis was to develop and utilize a biocompatible multifunctional trityl spin probe for concurrent measurement of pO2, pHe, and [Pi] in vivo by electron paramagnetic resonance (EPR) spectroscopy (Chapter 2). My first goal was to synthesize the proposed probe we are terming HOPE71. Secondly, HOPE71 was characterized by X-band and L-band EPR spectroscopy. Next, the biocompatibility of HOPE71 was assessed through an albumin binding test, cytotoxicity assays, and in vivo intravenous tolerance. Then, the use of HOPE71 to measure the target parameters was demonstrated in a breast cancer …
The Receptor Basis Of Serotonergic Modulation In An Olfactory Network, Tyler Ryan Sizemore
The Receptor Basis Of Serotonergic Modulation In An Olfactory Network, Tyler Ryan Sizemore
Graduate Theses, Dissertations, and Problem Reports
Neuromodulation is a nearly ubiquitous process that endows the nervous system with the capacity to alter neural function at every level (synaptic, circuit, network, etc.) without necessarily adding new neurons. Through the actions of neuromodulators, the existing neural circuitry can be adaptively tuned to achieve flexible network output and similarly dynamic behavioral output. However, despite their near ubiquity in all sensory modalities, the mechanisms underlying neuromodulation of sensory processing remain poorly understood. In this dissertation, I address three main questions regarding the mechanisms of one modulator (serotonin) within one sensory modality (olfaction). I begin by establishing a "functional atlas" of …
