Determination of the gross edge of a tumor is required during patient staging, assessing response to therapy, and for planning and executing surgical resection of locally invasive neoplasms. Disagreement in determination of the gross edge of the tumor is likely to directly affect patient staging, assessing response to therapy and...
Feline injection site sarcomas (FISS) are frequently encountered cutaneous and subcutaneous neoplasms of cats. Significant patient morbidity is related to the invasiveness these tumors display, typically requiring extensive local excision or amputation. As with many veterinary tumors, survival time and tumor recurrence for FISS is highly influenced by histologic margin...
This thesis presents two related studies on the methodology for creating, and
subsequently analyzing, an inverse food web model of an intertidal seagrass bed. The first study (Chapter 2) describes, for the first time in the literature, a method for incorporating isotopic information gained from Bayesian mixing models into an...
Platelet-rich plasma (PRP) has been applied as a hemostatic agent since the 1970s, and a potent source of autologous growth factors since the 1990s. PRP is rich in growth factors such as platelet derived growth factor (PDGF), vascular endothelial growth factor (VEGF), transforming growth factor-β (TGF-β), fibroblast growth factor (FGF)...
Availability of suitable nesting habitat that is free of nest predators and provides access to adequate prey resources within commuting distance is a major factor limiting seabird populations. Caspian terns (Hydroprogne caspia) in western North America have shifted their breeding habitat from naturally occurring habitats in interior wetlands, lakes, and...
Mass Spectrometry has emerged as an analytical core technique in omics sciences, in particularly mass spectrometry has advanced the fields of proteomics, metabolomics and lipidomics in recent years. Mass spectrometric techniques have enabled the characterization and determination of abundance levels of a wide range of biomolecules at molecular and system-wide...
Despite advances in treatment, cancer remains among the leading causes of death in the world. Progress in the treatment of metastatic cancers was seen with chemotherapy and radiotherapy, however, the major drawbacks of conventional cancer therapies are limited efficacy and severe side effects. Magnetic fluid hyperthermia (MFH) is a new...
Personal health monitoring tools, a subset of point-of care-diagnostics, enable more frequent testing of chronic health conditions outside of a clinic setting and can inform personalized therapy or support telehealth diagnostic capabilities. While there is evidence that regular monitoring of chronic conditions can lead to better health outcomes and lower...
OSU Libraries & Press initiated a pilot Open Access Fund in April 2015 that paid for open access article processing charges for OSU authors who met award criteria. The purpose of the fund was to heighten the visibility and accessibility of OSU scholarship and to support faculty and their student...
• Bladder Cancer in the United States has
progressively been one of the more common
cancers and is estimated to have 74,000 new
cases as well as 16,000 deaths in 2015.1
• This type of cancer also has one of the highest
rates of recurrence with an average of 60%...
Ewing sarcoma (EwS) is the second most highly malignant tumor that arises mainly from bone and surrounding soft tissue of adolescent and young adult patients. Despite the advances in Ewing sarcoma treatment that today include a combination of five chemotherapeutic agents, surgery, and/or radiotherapy, these therapies have demonstrated limited improvement...
This work expands the field of indoor free-space optical communication by introducing novel techniques in short range optical communication. The increasing need for high bandwidth communication necessitates the transition to optical frequencies with hundreds of terahertz worth of unregulated bandwidth. Optical communication offers an inherent security advantage over traditional communications...
Remote health monitoring tools have significant potential to revolutionize the current healthcare paradigm. Such tools could improve efficiencies in healthcare by alerting patients and doctors to abnormal health conditions in real time, shortening the time to diagnose and treat ailments. To meet these needs, we pursue the development of fabric-based...
Cancer is the second leading cause of death in the United States. To date, over 60% of current anticancer drugs were inspired by the discovery of chemical structure from nature, commonly known as a natural product. This work represents the biological characterization of several marine natural product compounds and their...
Paper-based microfluidic assays, like the common pregnancy test, allow for rapid screening at the point- of-care at low cost and with no instrumentation. Fabric has many similar properties to paper, but is more flexible and durable, making it a promising option for use in a variety of diagnostic and screening...
The serotonergic system plays a significant regulatory role in osteoblast differentiation and proliferation. Serotonin (five-hydroxytryptamine or 5HT) may promote or inhibit osteoblast proliferation depending upon the serotonin receptor isoforms expressed by the cell. Classically, 5HT receptor 1B (5HTR1B) reduces osteoblast proliferation by inhibiting phosphorylation of the cAMP response element binding...
Ovarian cancer, “the silent killer,” is one of the deadliest gynecological diseases due to delayed diagnosis, leading to a heavily disseminated and aggressive metastatic cancer. Therapeutic options are limited at stages III-IV of ovarian cancer, in which debulking surgery and cytotoxic chemotherapy remain the mainstays of
intervention. However, these therapeutic...
An increased understanding of secondary metabolism in fungi is important for both biological and societal reasons. The ascomycete genus, Tolypocladium, is an ideal system to explore secondary metabolism characterization, ecology, evolution and regulation. The genus produces and has the genomic potential to produce a wide array of metabolites. Paired with...
Ph.D. candidate Qi Wei's thesis consists of two projects: Chemotherapy Project: a study based on the research paper "Predicting chemotherapy response of various cancer types using a variational auto-encoder approach" submitted to the bioRxiv preprint archive and accepted by the BMC bioinformatics; and Wound Monitor Project: implementing and assessing analytics...
