Effect Of Tidal Cycling Rate On The Distribution And Abundance Of Nitrogen-Oxidizing Bacteria In A Bench-Scale Fill-And-Drain Bioreactor, Joseph M. Battistelli, Rima B. Franklin, Aaron L. Mills

Biology Publications

Most domestic wastewater can be effectively treated for secondary uses by engineered biological systems. These systems rely on microbial activity to reduce nitrogen (N) content of the reclaimed water. Such systems often employ a tidal-flow process to minimize space requirements for the coupling of aerobic and anaerobic metabolic processes. In this study, laboratory-scale tidal-flow treatment systems were studied to determine how the frequency and duration of tidal cycling may impact reactor performance. Fluorescent in situ hybridization and epifluorescence microscopy were used to enumerate the key functional groups of bacteria responsible for nitrification and anaerobic ammonium oxidation (anammox), and N-removal efficiency …

Functional Analysis Of Protease Adamts 6 During Vertebrate Eye Formation, Austin Taylor

Lewis Honors College Capstone Collection

Extracellular matrix (ECM) remodeling and epithelial sheet fusion occur during the development of many different tissues, including the vertebrate eye (Lu et al., 2011) (Pai et al., 2012). During morphogenesis of the eye, the ventral hemisphere of the developing retinal tissue forms an opening called the optic fissure which must undergo epithelial fusion (Pai et al., 2012). Failure of optic fissure fusion leads to a congenital blinding disorder called coloboma (Gregory-Evans, 2004). A long standing question pertaining to the mechanism of optic fissure fusion is exactly which ECM remodeling enzymes are actively involved in dismantling the ECM to allow for …

Does The Foundational Model Of Anatomy Ontology Provide A Knowledge Base For Learning And Assessment In Anatomy Education?, Melissa D. Clarkson, Mark E. Whipple

Institute for Biomedical Informatics Faculty Publications

Throughout the development of the Foundational Model of Anatomy (FMA) ontology, one of the use cases put forth has been anatomy education. In this work, we examine which types of knowledge taught to anatomy students can be supported by the FMA knowledge base. We first categorize types of anatomical knowledge, then express these patterns in the form “Given ____, state ____”. Each of the 33 patterns was evaluated for whether this type of knowledge is compatible with the modeling and scope of the FMA.

Female Mate Choice Of Male Signals Is Unlikely To Promote Ecological Adaptation In Enchenopa Treehoppers (Hemiptera: Membracidae), Kasey Fowler-Finn, Joseph T. Kilmer, Daniel C. Cruz, Rafael Rodriguez

Biological Sciences Faculty Articles

A key question in speciation research is how ecological and sexual divergence arise and interact. We tested the hypothesis that mate choice causes local adaptation and ecological divergence using the rationale that the performance~signal trait relationship should parallel the attractiveness~signal trait relationship. We used female fecundity as a measure of ecological performance. We used a species in the Enchenopa binotata treehopper complex, wherein speciation involves adaptation to novel environments and divergence in sexual communication. We used a full-sibling, split-family rearing design to estimate genetic correlations (r_G) between fecundity and signal traits, and compared those relationships against population-level …

Treatment Outcomes Of Mohs Surgery Vs. Imiquimod In Basal Cell Carcinoma, Mir Saleem, Julianna Robinson

Biology Faculty Articles

Background: Basal Cell Carcinoma (BCC) is a type of skin cancer, and a growing number of cases are diagnosed each year. There are many treatment options available, however finding the best treatment that has the lowest recurrence rate and morbidity is a challenge. The treatment options vary from topical or systemic medications to special procedures to surgical interventions. Treatment’s effectiveness largely differs on the BCC sub-type and its individual features. Method: Data was collected from the charts of patients that were diagnosed with BCC. The selected patients were treated by either Mosh surgery or Imiquimod. Results: Majority …

The Roles Of Inter- And Intra-Sexual Selection In Behavioral Isolation Between Native And Invasive Pupfishes, Cory Becher, Jennifer M. Gumm

Faculty Publications

Male-male competition and female mate choice may both play important roles in driving and maintaining reproductive isolation between species. When previously allopatric species come into secondary contact with each other due to introductions, they provide an opportunity to evaluate the identity and strength of reproductive isolating mechanisms. If reproductive isolation is not maintained, hybridization may occur. We examined how reproductive isolating mechanisms mediate hybridization between endemic populations of the Red River pupfish Cyprinodon rubrofluviatilis and the recently introduced sheepshead minnow C. variegatus. In lab-based dominance trials, males of both species won the same number of competitions. However, male C. rubrofluviatilis …

The Effects Of Ultraviolet Light On Anthocyanin Accumulation In The Adventitious Roots Of Sedum Wrightii (Crassulaceae), Lila D. Kerr, Dennis A. Gravatt, Robert J. Wiggers

Faculty Publications

Several studies have supported the idea that anthocyanin accumulation may be a possible protection mechanism in plants against DNA damage caused by ultraviolet radiation (UV). This study explored the accumulation of anthocyanins in the adventitious root tips of Sedum wrightii using the following treatments: UVA, UVA+low UVB, and UVA+high UVB. Following exposure to UV radiation, samples were analyzed for anthocyanin accumulation using an ethanol extraction procedure. Using ELISA, additional root samples were analyzed for indicators of DNA damage: cyclobutane pyrimidine dimers (CPDs) and pyrimidine (6-4) pyrimidone dimers (6-4 PPs). The anthocyanin concentrations were significantly higher in the UVA + high …

Immunization By Radiotherapy: Enhancing An Immune-Mediated Abscopal Effect, Amy Steffen

Biology and Microbiology Graduate Students Plan B Research Projects

Radiotherapy aims to destroy tumors by inducing DNA damage in their cells at the local irradiation site. Its immune-mediated systemic effects, called abscopal effect, has shown to enhance anti-tumor immunity when combined with immune therapies and thus, have gained attention by researchers and clinicians to investigate. Below is a summary of the fundamentals of cancer and the immune system’s response to it, as well as the changes in the phenotype and microenvironment of tumor cells after exposure to radiation. Impacts of the abscopal effect and the induction of effective antitumor immunity with various immune therapy strategies will be outlined. The …

Increasing The Clinical Efficacy Of Radiotherapeutics For Solid Tumors By Inhibition Of Hypoxia Inducible Factor-1a, Austin Levi Walz

Biology and Microbiology Graduate Students Plan B Research Projects

Radiotherapy is commonly used in a variety of tumor types and is effective in control of long term progression and may be curative under certain circumstances. Radiotherapeutics have been shown to be the single most effective therapeutic for cancer and only account for 5% of the total cost. However, treatment of cells with radiation causes the tumor microenvironment to undergo changes and leads to cycles of hypoxia inside the tumor which allows for the cell to undergo angiogenesis, metastasize and may lead to repopulation of the tumor. Current systemic chemotherapeutics typically have an additive toxicity due to the unintended targeting …

A Review Of Multiple Sclerosis Treatments: Interferon Beta, Glatiramer Acetate, Fingolimod, And Natalizumab, Ryan Golden

Biology and Microbiology Graduate Students Plan B Research Projects

Multiple Sclerosis (MS) is an autoimmune disease in which the body’s own immune system works to demyelinate the myelin sheaths in the central nervous system. The beginning of the review will concentrate on the history of MS while also describing how MS, the disease, differs from that of normal immune responses. The review then shifts to the four different stages of MS and how to differentiate between the stages, since the treatment options are often dependent on the stage of MS that the patient is in. The main focus of this review is to take an in depth look on …

Microbial Communities And Their Impact On Bioenergy Crops In Dynamic Environments, Brandon Monier

Electronic Theses and Dissertations

Native perennial grasses, such as prairie cordgrass (PCG, Spartina pectinata Link), and switchgrass (SG, Panicum virgatum L.) have a great potential as bioenergy crops, because they require fewer inputs, produce more energy, and reduce greenhouse gas emissions in comparison to annual cropping systems such as corn and soybean. SG has been selected by the U.S. Department of Energy for development as bioenergy crop, but studies have shown that PCG can outcompete switchgrass in terms of biomass production. These crops can also form associations with a wide variety of plant growth promoting microbes including arbuscular mycorrhial (AM) fungi. In CHAPTER 2, …

The Contributions Of Fc Gamma Receptors And Macropinocytosis To The Internalization, Sorting And Clearance Of Antibody Coated Nanovesicles In Macrophages, George Opoku-Kusi Jr.

Electronic Theses and Dissertations

Macrophages are tissue-resident phagocytes that play critical roles in immune response and tissue homeostasis. They have a tremendous capacity to internalize objects of various sizes ranging from nanoscale viral particles to micron sized bacteria and tumor cells. This phenomenon, termed phagocytosis for the uptake of large particles, or endocytosis for the uptake of small particles, is integral to the immune response in multicellular organisms. Macrophages express FcγRs, which are tyrosine kinase receptors that bind IgG on an opsonized target. Binding of IgG Fc domain to the extracellular domain of an FcγR triggers signaling cascades that coordinate internalization of the opsonized …

Black-Tailed Prairie Dog (Cynomys Ludovicianus) State-And-Transition Model For Loamy Ecological Sites In Mlra 62 In Custer State Park, South Dakota, Mark R. Hendrix

Electronic Theses and Dissertations

Black-tailed prairie dogs (Cynomys ludovicianus) are native burrowing rodents that occupy large areas in the shortgrass and mixed-grass prairies of the Northern Great Plains. They are an important component of these prairie systems due to their impacts on plant communities. Currently State-and-Transition models (STMs) for grassland Ecological Site Descriptions (ESDs) address grazing by livestock as a major factor affecting states and phases within states. Impacts from other grazers, such as prairie dogs, are either not addressed directly, or are included only in a transition to a generalized early seral state. There are, however, dramatic differences in plant communities …
