Design And Synthesis Of Novel No-Drug Hybrid Compound And Green Catalytic Activity Evaluation Of Synthesized Silver Nanoparticles-Halloysite Nanocomposite, Majed Abdullah Bajaber Dec 2020

Design And Synthesis Of Novel No-Drug Hybrid Compound And Green Catalytic Activity Evaluation Of Synthesized Silver Nanoparticles-Halloysite Nanocomposite, Majed Abdullah Bajaber

LSU New Orleans Theses and Dissertations

Acetaminophen is a well-known analgesic that can manage pain and reduce fever. SCP-1 is a derivative of acetaminophen that showed significantly reduced hepatotoxicity and nephrotoxicity comparative to acetaminophen. Nitric oxides have been well known to play a key role in a wide variety of physiological and pathophysiological important processes. It was therefore of interest to synthesize a nitric oxide donor linked to SCP-1 that could have enhanced analgesic and antipyretic activity. A furoxan CAS 1609 as NO-donor was synthesized and linked to SCP-1 successfully. The furoxan CAS 1609 was initially synthesized from tetronic acid to give 1,2- dioxime in 86 …

Disparities In Oral Health: Socioeconomic Status And Policies To Increase Access To Primary Dental Care, Mckenzie Nutter Dec 2020

Disparities In Oral Health: Socioeconomic Status And Policies To Increase Access To Primary Dental Care, Mckenzie Nutter

Theses/Capstones/Creative Projects

Primary dental care is a patient-centered service consisting of routine dental checkups. The oral cavity is the first point of entrance to the body for many harmful pathogens. Therefore, primary dental care is essential to not only prevent and treat conditions in the mouth, but to also reduce the number of systemic diseases in the rest of the body. However, people with higher incomes or wealth have increased access to primary dental care. People with low socioeconomic status have decreased access to primary dental care, at least in part due to difficulties in paying for separate dental insurance. Disparities in …

Cultural Competence Objective Structured Clinical Examination For Student Nurse Anesthetists, Ashley Nicole Minor, Loryn Elise Jamison

Doctoral Projects

The landscape of ethnicity is growing increasingly diverse. In 2017, the U.S. Census Bureau estimated that by the time the 2020 Census is conducted, over half of the nation’s children will be of a minority group (U.S. Census Bureau, 2017). With this evolution in cultural variety comes a necessity to incorporate exposure and training of cultural competency into professional health programs. Student registered nurse anesthetists (SRNAs) are a key demographic to professional growth within the realms of cultural competence as related to the field of nurse anesthesia. Along with clinical skills and advanced knowledge, cultural competence should be equally developed. …

The Relationship Between Mindfulness, Academic Stress, And Attention, Tida Blackburn Dec 2020

The Relationship Between Mindfulness, Academic Stress, And Attention, Tida Blackburn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Some degree of anxiety in learning situations is expected and normal. However, excessive anxiety and stress negatively affect cognitive performance, especially working memory, concentration, and sustained attention. Studies have shown that higher success in academics is related to a better ability to maintain focus on the information presented including auditory and visual attention. College students who are better able to manage stress are more successful than those who cannot. One method of coping with stress and anxiety is the practice of mindfulness. Mindfulness is the ability to be fully present in the moment, be aware of one’s mind, body, and …

A Standardized Unit Based Process For Obtaining Heart Failure Patient Weights, Lesli E. Teed Dec 2020

A Standardized Unit Based Process For Obtaining Heart Failure Patient Weights, Lesli E. Teed

Master's Projects

Introduction: A CNL student-led process improvement process improvement project was proposed to help improve the accuracy of Heart Failure patient weights on a geriatric specialty unit. Cardiology voiced a preference for patients to be weighed using electronic standing scales rather than in-bed scales to improve accuracy. A literature review revealed that in-bed scale weights were less accurate due to inconsistencies in zeroing the bed prior to obtaining the weight, not removing excess patient care equipment and bed linens, and not ensuring that the patient was wearing a minimal amount of clothing.

Methods: Electronic standing scales were purchased, current practice state …

Ampakines Stimulate Phrenic Motor Output After Cervical Spinal Cord Injury, L. B. Wollman, Kristi A. Streeter, A. F. Fusco, E. J. Gonzalez-Rothi, M. S. Sandhu, J. J. Greer, D. D. Fuller Dec 2020

Ampakines Stimulate Phrenic Motor Output After Cervical Spinal Cord Injury, L. B. Wollman, Kristi A. Streeter, A. F. Fusco, E. J. Gonzalez-Rothi, M. S. Sandhu, J. J. Greer, D. D. Fuller

Physical Therapy Faculty Research and Publications

Activation of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors increases phrenic motor output. Ampakines are a class of drugs that are positive allosteric modulators of AMPA receptors. We hypothesized that 1) ampakines can stimulate phrenic activity after incomplete cervical spinal cord injury (SCI), and 2) pairing ampakines with brief hypoxia could enable sustained facilitation of phrenic bursting. Phrenic activity was recorded ipsilateral (IL) and contralateral (CL) to C2 spinal cord hemisection (C2Hx) in anesthetized adult rats. Two weeks after C2Hx, ampakine CX717 (15 mg/kg, i.v.) increased IL (61 ± 46% baseline, BL) and CL burst amplitude (47 ± 26%BL) in 8 of 8 …


Two Weeks Of Remote Ischemic Conditioning Improves Brachial Artery Flow Mediated Dilation In Chronic Stroke Survivors, Allison S. Hyngstrom, Jennifer Nguyen, Michael Wright, Sergey Tarima, Brian D. Schmit, David D. Gutterman, Matthew J. Durand Dec 2020

Two Weeks Of Remote Ischemic Conditioning Improves Brachial Artery Flow Mediated Dilation In Chronic Stroke Survivors, Allison S. Hyngstrom, Jennifer Nguyen, Michael Wright, Sergey Tarima, Brian D. Schmit, David D. Gutterman, Matthew J. Durand

Physical Therapy Faculty Research and Publications

Many stroke survivors have reduced cardiorespiratory fitness as a result of their stroke. Ischemic conditioning (IC) is a noninvasive, cost-effective, easy-to-administer intervention that can be performed at home and has been shown to improve both motor function in stroke survivors and vascular endothelial function in healthy individuals. In this study, we examined the effects of 2 wk of remote IC (RIC) on brachial artery flow mediated dilation (FMD) in chronic stroke survivors. We hypothesized that FMD would be improved following RIC compared with a sham RIC control group. This was a prospective, randomized, double-blinded, controlled study. Twenty-four chronic stroke survivors …


Plasma Resuscitation Attenuates Intestinal Barrier Disturbance Following Hemorrhagic Shock., Jessica E. Schucht Dec 2020

Plasma Resuscitation Attenuates Intestinal Barrier Disturbance Following Hemorrhagic Shock., Jessica E. Schucht

Electronic Theses and Dissertations

Background: Intestinal ischemia-reperfusion injury (IIRI) following resuscitated hemorrhagic shock (HS/RES) leads to endothelial damage, microcirculatory dysfunction and intestinal barrier breakdown, increasing intestinal permeability. This pathologic process contributes pathophysiology of multiple organ dysfunction syndrome (MODS) in some trauma patients. Although vascular smooth muscle machinery remains intact, microvascular vasoconstriction occurs secondary to endothelial cell damage, resulting in further ischemia and organ injury. Used separately, resuscitation with Fresh Frozen Plasma (FFP) or Direct Peritoneal Resuscitation (DPR) improves the intestinal microcirculation and alleviates organ injury. Further examination of these effects individually or combined could aid in the resuscitation of hemorrhagic shock. Methods: Sprague Dawley …


Characterization Of Adiposity And Inflammation Genetic Pleiotropy Underlying Cardiovascular Risk Factors In Hispanics., Mohammad Yaser (Anwar) Dec 2020

Characterization Of Adiposity And Inflammation Genetic Pleiotropy Underlying Cardiovascular Risk Factors In Hispanics., Mohammad Yaser (Anwar)

Electronic Theses and Dissertations

The observed overlap between genetic variants associated with both adiposity and inflammatory markers suggests that changes in both adiposity and inflammation could be partially mediated by common pathways. The pervasive but sparsely characterized “pleiotropic” genetic variants associated with both adiposity and inflammation have been hypothesized to provide insight into the shared biology. This study explored and characterized the genetic pleiotropy underpinning adiposity and inflammation using genetic and phenotypic observations from the Cameron County Hispanic Cohort (CCHC). A total of 3,313 samples and >9 million single nucleotide polymorphisms (SNPs) were examined in this study. Mixed model genome-wide association studies (GWAS) were …

Role Of Β-Glucan Structure In Dectin-1 Homo- And Hetero-Oligomerization In Innate Anti-Fungal Immunity, Eduardo U. Anaya Dec 2020

Role Of Β-Glucan Structure In Dectin-1 Homo- And Hetero-Oligomerization In Innate Anti-Fungal Immunity, Eduardo U. Anaya

Biomedical Sciences ETDs

Dectin-1A is a C-type Lectin innate immunoreceptor that recognizes β-(1,3)-glucan, a structural component of Candida species cell walls. Dectin-1 has eight alternative splice isoforms including, A and B. Innate immunocytes can express one or both isoforms, but neither their relative responsiveness to β-glucan nor the potential for inter-isoform signaling cross-talk is well understood. In this study, we determine how the different structures of soluble β-glucans affect both isoforms and unravel how differences in glucan structure impact the earliest events in Dectin-1 signaling. Using quantitative microscopy techniques, we explored the role of glucan structure on Dectin-1A oligomerization, which is thought to …


Disruption Of Dna Polymerase Zeta Promotes An Innate Immune Response, Sara Martin Dec 2020

Disruption Of Dna Polymerase Zeta Promotes An Innate Immune Response, Sara Martin

Dissertations and Theses (Open Access)

DNA polymerase ζ (pol ζ) is a specialized polymerase that protects cells from the consequences of DNA damage and stress. Without pol ζ function mammalian cells and yeast are exquisitely sensitive to genotoxic stresses including ultraviolet irradiation and platinum compounds such as the chemotherapeutic agent cisplatin. This elevated sensitivity arises from the central role of pol ζ in lesion bypass. Pol ζ is also required to protect cells from endogenous genomic damage or stress. In primary mammalian cells, the function of pol ζ is required for genome protection and normal proliferation. Immortalized Rev3lknockout (KO) MEFs are under considerable constitutive …
