Aryne-Guided C-H Functionalization Of Benzenoid Rings Using Diaryliodonium Salts, Aleksandra Nilova Nov 2020

Aryne-Guided C-H Functionalization Of Benzenoid Rings Using Diaryliodonium Salts, Aleksandra Nilova

Dissertations and Theses

The benzenoid core is a frequent and irreplaceable component of biologically active molecules. Structure function relationship of these compounds has been broadly analyzed and presented in numerous literature reports. Herein, we augmented existing knowledge by a broad analysis of the benzenoid substitution patterns in small molecule active pharmaceutical ingredients approved by the FDA. Our findings reveal a strong correlation that the most represented substitution patterns are those achieved via SEAr. Despite the rapid development of methods to functionalize benzenoid rings, the lack of synthetic methodologies to access sterically and electronically unfavorable positions is highlighted. We sought to establish …

Microplastics In Pacific Northwest Bivalves: Ecological Prevalence, Harvester-Consumer Exposure, And Aquarium Exhibit Outcomes, Britta Rahel Baechler

Dissertations and Theses

Up to 23 million metric tons of mismanaged plastics enter the global ocean annually. Microplastics (MPs;<5mm) degrading. MPs leak into the environment and now pervade every corner of the earth, with implications for animal, plant, ecosystem and human health. It is important to understand localized environmental MP prevalence, distribution and organismal uptake in order to determine the extent of MP pollution, and ultimately unlock solution sets to reduce transmission of MPs into the natural world. In Chapter 2, I quantified MP types, concentrations, anatomical burdens, geographic distribution, and temporal differences in Pacific oysters (Crassostrea gigas) and Pacific razor clams (Siliqua patula) from 15 coastal sites in Oregon. Both of these species are integral to culture, economy, gastronomy and food security along the United States West Coast. In Chapter 3, I quantified MPs in Pacific razor clams collected from 8 Olympic Coast, Washington sites, administered questionnaires to recreational razor clammers and subsequently estimated annual MP exposure of those Olympic Coast razor clam harvester-consumers surveyed. In Chapter 4, I designed and installed an educational ocean plastic …

Compost And Biochar To Promote Soil Biological Activities Under Sweet Potatoes Cultivation In A Subtropical Semiarid Region, Josabeth Navarro, Jahdiel Salazar, James Jihoon Kang, Jason Parsons, Chu-Lin Cheng, Alexandria Castillo, Engil Isadora Pujol Pereira

School of Earth, Environmental, & Marine Sciences Faculty Publications

South Texas is located in a subtropical semiarid climate, and due to high temperature and irregular precipitation, farmers opt to leave their fields fallow during the summer months jeopardizing overall soil health. We evaluated whether sweet potato (Ipomoea batatas) cultivation coupled with drip irrigation could restore soil biological activities compared with bare fallow. Additionally, because sweet potatoes have high demand of soil nutrients, especially potassium (K), we evaluated the nutrient supply of locally sourced soil amendments. Sweet potato was cultivated during summer 2018 in McAllen, Texas, under control (no fertilizer), NPK (synthetic fertilizer), RC (yard-waste compost), and AC (compost produced …

Faculty and Staff Publications

The biomechanical and adaptive significance of variation in craniodental and mandibular morphology in fossil hominins is not always clear, at least in part because of a poor understanding of how different feeding behaviors impact feeding system design (form-function relationships). While laboratory studies suggest that ingestive behaviors produce variable loading, stress, and strain regimes in the cranium and mandible, understanding the relative importance of these behaviors for feeding system design requires data on their use in wild populations. Here we assess the frequencies and durations of manual, ingestive, and masticatory behaviors from more than 1400 observations of feeding behaviors video-recorded in …

Smoking Behaviors In Patients Offered Lung Cancer Screening, Sara Elizabeth Golden Nov 2020

Smoking Behaviors In Patients Offered Lung Cancer Screening, Sara Elizabeth Golden

Dissertations and Theses

In the United States, smoking causes preventable diseases, including lung cancer, which is the leading cause of cancer deaths. Improving smoking cessation rates is important to decrease lung cancer deaths. Health care visits with a discussion about lung cancer screening (LCS) may help in increasing prevalence of smoking cessation. Importantly, insurers now require clinicians to have a shared decision-making discussion with patients that includes discussion of smoking abstinence before they can receive an LCS scan (i.e., a low-dose computed tomography scan). This discussion may represent a unique opportunity to encourage smoking cessation since it may prompt positive smoking behavior change. …

Association Of Insulin Resistance With Overactive Bladder Syndrome In Female Patients, Anwar Al- Bassam, Hadeel Kareem, Saba Shaker Nov 2020

Association Of Insulin Resistance With Overactive Bladder Syndrome In Female Patients, Anwar Al- Bassam, Hadeel Kareem, Saba Shaker

Iraqi Postgraduate Medical Journal

BACKGROUND: Overactive bladder Syndrome refers to a group of lower urinary tract symptoms related to the storage of urine in the bladder. Normally the bladder fills and stores urine without discomfort or leakage. The sensation of bladder fullness gradually increases until the need to void comes to conscious awareness. In those who have overactive bladder, however, the sensation to void is altered (and generally delayed) to the extent that involuntary urination may occur. current evidence suggests that it may be associated with insulin resistance  . AIM OF STUDY: We aimed to investigate the association of insulin resistance with overactive bladder …

Extending Power Series Methods For The Hodgkin-Huxley Equations, Including Sensitive Dependence, James S. Sochacki Nov 2020

Extending Power Series Methods For The Hodgkin-Huxley Equations, Including Sensitive Dependence, James S. Sochacki

CODEE Journal

A neural cell or neuron is the basic building block of the brain and transmits information to other neurons. This paper demonstrates the complicated dynamics of the neuron through a numerical study of the Hodgkin-Huxley differential equations that model the ionic mechanisms of the neuron: slight changes in parameter values and inputted electrical impulses can lead to very different (unexpected) results. The methods and ideas developed for the ordinary differential equations are extended to partial differential equations for Hodgkin-Huxley networks of neurons in one, two and three dimensions.

Criminology As Epistemic Necropolitics, Tamari Kitossa Phd Nov 2020

Criminology As Epistemic Necropolitics, Tamari Kitossa Phd

Social Transformations Journal of the Global South

I argue in this essay that from 1492 to the present, the Global North has used theories of “crime,” its causation and control, as part of a three-pronged epistemic necropolitical attack on the Global South. I suggest that the emergence of critical criminology and its more recent offshoots, given their dependence on the present or hypothetical war making and coercive state, are themselves a part of the problem. I suggest criminology is a Trojan Horse that brings epistemic toxic waste and destruction in the guise of deterministic theories on crime and its control. Like their Inquisitorial predecessors, I suggest criminology …

Shifting The 'White Gaze' On Black Bodies In Philippine Collegiate Basketball: Toward A Structural Understanding Of Covert Racism In The Global South, Satwinder Singh Rehal Nov 2020

Shifting The 'White Gaze' On Black Bodies In Philippine Collegiate Basketball: Toward A Structural Understanding Of Covert Racism In The Global South, Satwinder Singh Rehal

Social Transformations Journal of the Global South

In a postcolonial Global South context, the representation of race seems to persist and is manifested through the media scripting of Black African sporting bodies that in effect extends the deployment of the “White gaze,” the effort to explore the Black body within the context of white supremacy. Through a qualitative content analysis of media texts in the Philippines, the paper illustrates how in a postmodern context racial stereotypes literally play out within Philippine collegiate basketball framed by the “White gaze” that expresses a covert form of racism that supports an essentialist deployment of categories of race. The paper ends …

Counselor Preparation In Crisis, Trauma, Grief, And Neurocounseling, Karlesia T. Montague, Katie Christensen, Susan Furr Nov 2020

Counselor Preparation In Crisis, Trauma, Grief, And Neurocounseling, Karlesia T. Montague, Katie Christensen, Susan Furr

Journal of Counselor Preparation and Supervision

Crisis, trauma, and grief are common themes in counseling while neurocounseling is a relatively new term that has increased presence in counseling. However, little is known about the current status of CACREP programs offering courses directly preparing counselors to address these concerns. This descriptive study analyzed CACREP programs (N = 392) to determine how many counselor education programs offered courses in each special topic. Results indicated that programs offered crisis courses at the highest rate (62.2%) compared to trauma (41%), grief (21.2%), and neurocounseling (5.1%). These results examined program offerings immediately following the CACREP 2016 Standards revisions and may …

Biomechanical Comparison Of The Validity Of Two Configurations Of Simulators For Body-Powered Hand Prostheses, Camille Bennett, Amanuel Matias, Brendan Smith, Jenevieve Roper, Stephen Estelle Nov 2020

Biomechanical Comparison Of The Validity Of Two Configurations Of Simulators For Body-Powered Hand Prostheses, Camille Bennett, Amanuel Matias, Brendan Smith, Jenevieve Roper, Stephen Estelle

Honors Thesis

Simulators are often used in prosthesis research to evaluate new devices or characterize aspects of prosthesis use, so as to recruit participants without amputations. Simulators, in general, must locate the prosthesis somewhere other than where the intact biological limb exists. In this study, we compared two configurations of simulators for hand prostheses to determine which leads to more natural elbow and shoulder kinematics, and in turn, which is the more valid simulator. One configuration located the prosthesis in-line with the forearm, beyond the biological hand; the other located it beside the hand. We measured the kinematics of 12 non-amputee participants …

Death Sentence: A Compendium Against Assailment, John F. Serafine Nov 2020

Death Sentence: A Compendium Against Assailment, John F. Serafine

Lincoln Memorial University Law Review Archive

Getting people to kill themselves is the oldest trick in the book. There ought to be a constitutional law against it. This Article proposes one.“Assailment” means asking, telling, or tempting a person under the age of eighteen to attempt or complete suicide. It also includes extorting or blackmailing a child into suicidal behavior. Such a law is necessary because of the skyrocketing rate of youth suicide. Death Sentence: A Compendium Against Assailment encourages lawmakers to enact an assailment statute. It further tells the stories of 41 completed youth suicides, 15 attempts, and 8 cases of suicidal ideation. The rigors of …

Immunohistochemical Localization Of Prolactin Receptor (Prlr) To Hodgkin's And Reed-Sternberg Cells Of Hodgkin's Lymphoma, Rajendra Gharbaran, Onyekwere Onwumere, Naomi Codrington, Latchman Somenarian, Stephen Redenti

Publications and Research

Prolactin receptor (PRLR), a type-1 cytokine receptor, is overexpressed in a number of cancer types. It has attracted much attention for putative pro-oncogenic roles, which however, remains controversial in some malignancies. In this study, we reported the localization of PRLR to the Hodgkin's and Reed-Sternberg (HRS) cells of Hodgkin's lymphoma (HL), a neoplasm of predominantly B cell origin. Immunohistochemistry performed on 5-μm thick FFPE sections revealed expression of PRLR in HRS cells. Cellular immunofluorescence experiments showed that the HL-derived cell lines, Hs445, KMH2 and L428 overexpressed PRLR. The PRLR immunofluorescent signal was depleted after treating the cell lines with 10 …
