  • Are they what they eat? A stable GIT microbiome characterized in P. resecata

    Creator:
    Gustafson, Tarah N.
    Abstract:
    Intertidal herbivores, such as isopods, help regulate and contribute to nutrient cycling and organic carbon flow through the trophic levels in estuaries and coastal ecosystems. Though much is known about the microbiomes of macrophyte leaves that serve as the primary food source for isopods, and (to a lesser extent) the...

  • Numerical Effects on Timing System Pathways

    Creator:
    Steiner, Samantha K.
    Abstract:
    Studying human’s ability to estimate temporal durations could lead to a greater understanding of our cognitive abilities as well as the processes that underlie temporal estimation. It has been shown through previous research that time and number may be interconnected cognitively and that the magnitude of one may alter the...

  • Site-Specific Modification of Glucose Proteins Enabling Precise Surface Orientation For Glucose Sensors

    Creator:
    Wolfenden, Nurhayati
    Abstract:
    An ideal labeling reaction between protein and surface should generate a protein-patterned surface with control over the orientation of the desired protein. Controlling orientation would generate a homogeneous, un-fouled protein surface and allow for maximum efficiency in regards to the activity, reactivity, and stability of the protein. In this research...

  • Investigation of the effects of cryopreservation on cellular viability and mechanical integrity of the intervertebral disc

    Creator:
    Forcier, Ryan J.
    Abstract:
    Degeneration of the intervertebral disc (IVD) is a phenomenon that has yet to be adequately addressed. Treatment options remain limited and incomplete. The ability to effectively cryopreserve IVDs would allow for better allograft transplantations and storage of samples for research purposes. This study aimed to assess how cryopreservation with different...

  • Selection of an Orthogonal tRNA Synthetase for Trifluoromethyl-phenylalanine in Methanomethylophilus Alvus System

    Creator:
    Eyberg, Daniel R.
    Abstract:
    Genetic code expansion is a technology that allows for site-specific incorporation of noncanonical amino acids into recombinant proteins at amber stop codons using engineered translational machinery. The technology allows for expanded study into proteins, derived from the integration of novel chemical functions found in noncanonical amino acids, such as fluorescence,...

  • Controlled Orientation of Engineered Carbonic Anhydrase on a Surface : A Model for Protein Immobilization for Biosensors and Biomaterials

    Creator:
    Brown, Wesley
    Abstract:
    Current protein immobilization techniques lack defined control over protein orientation. Protein orientation is important for making biosensors and biomaterials that are sensitive and efficient and can be crucial for designing some devices such as immunosensors or direct electron transferring biocells. A new method of protein immobilization is proposed that takes...

  • Characterizing the Interactome of Nitrotyrosine-Calmodulin using Genetic Code Expansion

    Creator:
    Kong, Garth L.
    Abstract:
    A specific tyrosine post-translational modification, called 3-nitro-tyrosine (nitroTyr), has been known to be present on an essential calcium signaling protein called calmodulin (CaM) during oxidative stress. While protein-bound 3-nitro-tyrosine has long been considered a biomarker of OS, it is also hypothesized to be a mechanism for protein signaling. However, purification...

  • Tuning tRNA and EF-Tu for the Efficient Site-specific Incorporation of Noncanonical Amino Acids into Proteins

    Creator:
    Gottfried-Lee, Ilana L.
    Abstract:
    Genetic code expansion (GCE) is a technology that allows us to incorporate noncanonical amino acids (ncAAs) site-specifically into recombinant proteins using engineered translational machinery. Typically, an orthogonal aaRS/tRNA pair is engineered by directed evolution to recognize the ncAA and incorporate it at a reassigned codon while not interacting with the...

  • Photoactuated Droplet Microfluidics

    Creator:
    Frederick, Ryan T.
    Abstract:
    A system of Photoactuated Droplet Microfluidics (PDM), in which a droplet of fluid is moved by way of the manipulation of the wettability of a spiropyran functionalized surface via irradiation with ultraviolet and visible light, was proposed. The photochromic behaviors of several species of spiropyran were studied and a procedure...

  • Cancer Cell Detection with Mask R-CNN

    Creator:
    Wong, Ryan
    Abstract:
    Instance segmentation, the classification and localization of objects in an image, is a problem in cellular biophysics due to the physiological relevance of cell morphology. Particularly, cancer cells migrate in tissue space by changing their body shape similarly to how humans extend their limbs to swim through water. Monitoring such...
