Saphenous Vein Harvesting With Endoscopy Versus No-Touch Technique: Short-Term Results, Tamer El Bannaa, Mohamed M. Mohamed, Ahmed Zayed, Yasser A. Sadek

Journal of Medicine in Scientific Research

Objective ‘No-touch’ (NT) saphenous vein harvesting maintains vasa vasorum, resulting in less medial ischemic affection, which leads to improved short-term and long-term patency. However, it may also be associated with a higher rate of wound complications. Endovascular vein harvesting (EVH) has a low rate of wound complications but also a tendency toward a lower patency rate. The aim was to compare wound complications and short-term symptomatic relief, which could be an indication of functioning grafts. Patients and methods During a 2-year period (2018–2019), in a nonrandomized prospective study, we monitored patients after coronary artery bypass graft for recurrence of ischemic …

Knockout Of Endospanin 1 Via Crispr In Zebrafish, Danio Rerio, Jared Kittinger

Williams Honors College, Honors Research Projects

I made endospanin 1 knockout (KO) zebrafish to examine its effects on lipid and bone metabolism. Endospanin 1, or leptin receptor overlapping transcript (leprot), is a cytosolic protein linked to the protein hormone leptin that influences the trafficking of leptin receptors to the plasma membrane of cells. Genes for endospanin and tyrosinase (a pigmentation enzyme) were targeted via a microinjection of guide RNAs and CRISPR Cas9 into zebrafish embryos at 2-4 cell stages. I was able to disrupt the endospanin 1 gene (based upon the disruption of tyrosinase), but very few mutant zebrafish fully developed into adults. Only low KO …

Mouthpiece For Patients With Neuromuscular Disorders, Rebekah Starkey, Carissa Thompson, Michael Dickens, Andrew Pero Jan 2023

Mouthpiece For Patients With Neuromuscular Disorders, Rebekah Starkey, Carissa Thompson, Michael Dickens, Andrew Pero

Williams Honors College, Honors Research Projects

Neuromuscular Disorders (NMDs) impact people throughout the world. An early hallmark of these disorders includes some degree of facial muscle weakness. Respiratory testing is important to evaluate the progression of these patients’ NMDs. However, these tests require that the patient purses their lips around a mouthpiece to create a tight seal. This is a difficult task for one with facial muscle degeneration. This often leads to results that fail to reflect the patient’s true respiratory ability and prevents their physician from providing the appropriate degree of care. The objective of this project was to develop a face mask or mouthpiece …

An Examination Of The Role Of Adrenergic Receptor Stimulation In Mediating The Link Between Early-Life Stress And The Sensitization Of Neuroinflammatory-Based Depressive-Like Behavior In Isolated Guinea Pig Pups, Rachel Renate Kessler Jan 2023

An Examination Of The Role Of Adrenergic Receptor Stimulation In Mediating The Link Between Early-Life Stress And The Sensitization Of Neuroinflammatory-Based Depressive-Like Behavior In Isolated Guinea Pig Pups, Rachel Renate Kessler

Browse all Theses and Dissertations

Early-life stress appears to sensitize neuroinflammatory signaling to increase later vulnerability for stress-related mental disorders. How stress initiates this process is unknown, but sympathetic nervous system activation during the early stress may be key. Isolated guinea pig pups display inflammatory-mediated depressive-like behavior and fever that sensitize on repeated isolation. We assessed whether sympathetic nervous system activity contributed to the sensitization process in guinea pig pups. In Experiment 1, the adrenergic agonist ephedrine, either alone or with cortisol, did not increase depressive-like behavior or fever during an initial isolation the following day. In Experiment 2, both depressive-like behavior and fever sensitized …

Department of Speech, Language, and Hearing Sciences Faculty Publications

Purpose: Providing culturally responsive care for a diverse patient population is critical for future speech-language pathologists and audiologists. Prior studies have shown gains in intercultural competence (ICC) from study abroad programs, face-to-face classes, and online courses; however, limited studies have investigated differences between face-to-face and online modes of delivery in speech-language pathology and audiology. The purpose of this study was (a) to evaluate whether there are quantitative differences in development of ICC in a direct comparison of a face-to-face and 100% asynchronous online introductory in communication dis-orders, and (b) to describe participants learning through the structural intercultural learning activities embedded …


The Heads-Ed: A Psychosocial Screening For Pediatric Patients In Emergency Departments: A Systematic Review, Jessica Burns Jan 2023

The Heads-Ed: A Psychosocial Screening For Pediatric Patients In Emergency Departments: A Systematic Review, Jessica Burns

Theses and Dissertations

The rates of mental health (MH) conditions among the pediatric population are rising steadily (Abramson, 2022; Clark et al., 2019). Given that MH symptoms and concerns frequently present in the emergency department (ED)-particularly since the onset of the COVID-19 pandemic-the ED setting may be a practical and effective setting to implement screening measures to identify youth at risk for mental illness and suicide (Leeb et al., 2020; Leff et al., 2021). This integrative systematic review examined the extent to which the HEADS-ED, one specific psychosocial screening measure, has been administered in the ED setting with youth and which healthcare professionals …


Black Midwives For Black Mothers: Ameliorating Racial Disparities In The Quality Of Maternal Healthcare, Kimberly Navarro Jan 2023

Black Midwives For Black Mothers: Ameliorating Racial Disparities In The Quality Of Maternal Healthcare, Kimberly Navarro

Theses and Dissertations

In the United States, maternal mortality represents a dire health crisis with a stark racial imbalance. Black women are two and a half to three times more likely to die from pregnancy and birth-related complications than their White counterparts. Racial disparities in maternal health can be explained by variations in the quality of maternal healthcare services that women tend to receive. Racial and ethnic minority women are more likely to receive inferior quality prenatal care (PNC), which brings to question the care model of traditional PNC and its adequacy in serving the healthcare needs of Black women. Since Black women …

A systematic review was conducted and identified nine studies for inclusion. Results highlight seven themes focusing on bilingual Spanish-English Latinx …


Internal Medicine Interns' Perceived Preparation For Residency And Perceived Value Of Non-Surgical Ttr Course, Anthony Gaynier Jan 2023

Internal Medicine Interns' Perceived Preparation For Residency And Perceived Value Of Non-Surgical Ttr Course, Anthony Gaynier

Wayne State University Dissertations

Transition to residency (TTR) courses have become increasingly popular in medical schools. Yet there is limited data on interns’ perceived preparation for residency and the value of non-surgical TTR courses and their common components. Research has shown that TTR courses increase medical knowledge, clinical skills, and an increase in confidence in participants, but still incoming residents still do not feel prepared for the start of residency. Currently, there are only a few single institution studies researching interns’ perceived value of TTR courses.

This quantitative study surveyed internal medicine interns at five residency programs to find their preparation for residency, their …


The Mechanisms Of Trail Resistance In Triple-Negative Breast Cancer, Julio Macias Pimentel Jan 2023

The Mechanisms Of Trail Resistance In Triple-Negative Breast Cancer, Julio Macias Pimentel

Wayne State University Dissertations

Triple-negative breast cancer (TNBC) is an aggressive form of breast cancer that lacks targeted therapies. Previous studies have shown that TNBC cells are highly sensitive to tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL), making it a promising agent for treating TNBC. However, the development of TRAIL resistance limits its further clinical development, and the underlying mechanisms are not fully understood. In this study, we report the role of PD-L1 and inflammation in TRAIL resistance. Specifically, we found that TRAIL treatment increases PD-L1 expression in TRAIL-sensitive cells and that basal PD-L1 expression is increased in acquired TRAIL-resistant cells. Mechanistically, we found …


Mechanistic Insights Into The Therapeutic Potential Of Adjunctive Thymosin Beta-4 Treatment In Pseudomonas Aeruginosa-Induced Keratitis, Yuxin Wang Jan 2023

Mechanistic Insights Into The Therapeutic Potential Of Adjunctive Thymosin Beta-4 Treatment In Pseudomonas Aeruginosa-Induced Keratitis, Yuxin Wang

Wayne State University Dissertations

Tβ4, a naturally occurring 43-amino acid protein, has been found to promote wound healing and reduce corneal inflammation. Topical Tβ4 as a therapeutic agent in conjunction with ciprofloxacin improves the outcome of Pseudomonas aeruginosa-induced keratitis by regulating the cellular functions of PMNs and MΦs and enhancing the production of SPMs. Understanding the mechanisms of Tβ4 provides valuable insights and novel therapeutic potential for resolving disease pathogenesis not only in the cornea but also in other infectious and immune-regulated inflammatory conditions.

Defining County-Level Terrestrial Rabies Freedom Using The Us National Rabies Surveillance System: Surveillance Data Analysis, Amber Kunkel, Gabriella Veytsel, Sarah C. Bonaparte, Haillie Meek, Xiaoyue Ma, Amy J. Davis, Jesse Bonwitt, Ryan M. Wallace

United States Department of Agriculture Wildlife Services: Staff Publications

Background: Rabies is a deadly zoonotic disease with nearly 100% fatality rate. In the United States, rabies virus persists in wildlife reservoirs, with occasional spillover into humans and domestic animals. The distribution of reservoir hosts in US counties plays an important role in public health decision-making, including the recommendation of lifesaving postexposure prophylaxis upon suspected rabies exposures. Furthermore, in surveillance data, it is difficult to discern whether counties have no cases reported because rabies was not present or because counties have an unreported rabies presence. These epizootics are monitored by the National Rabies Surveillance System (NRSS), to which approximately 130 …

Deriving Spatially Explicit Direct And Indirect Interaction Networks From Animal Movement Data, Anni Yang, Mark Q. Wilber, Kezia R. Manlove, Ryan S. Miller, Raoul Boughton, James Beasley, Joseph Northrup, Kurt C. Vercauteren, George Wittemyer, Kim Pepin

United States Department of Agriculture Wildlife Services: Staff Publications

Quantifying spatiotemporally explicit interactions within animal populations facilitates the understanding of social structure and its relationship with ecological processes. Data from animal tracking technologies (Global Positioning Systems [“GPS”]) can circumvent longstanding challenges in the estimation of spatiotemporally explicit interactions, but the discrete nature and coarse temporal resolution of data mean that ephemeral interactions that occur between consecutive GPS locations go undetected. Here, we developed a method to quantify individual and spatial patterns of interaction using continuous-time movement models (CTMMs) fit to GPS tracking data. We first applied CTMMs to infer the full movement trajectories at an arbitrarily fine temporal scale …

Long Term Changes In Aquaculture Influence Migration, Regional Abundance, And Distribution Of An Avian Species, Paul C. Burr, Brian S. Dorr, Jimmy L. Avery, Garrett M. Street, Bronson K. Strickland

United States Department of Agriculture Wildlife Services: Staff Publications

Agricultural development has been causing changes to the environment and the abundance and distribution of avian species. Agriculture is dynamic with changes in products occurring at large scales over relatively short time periods. The catfish aquaculture industry is one such agriculture industry that has undergone dramatic changes over the last 25 years. The double-crested cormorant (Nannopterum auritum) is a piscivorous bird that has an extensive history with the aquaculture industry of Mississippi due to its depredation of cultured catfish. A large-scale monitoring program began in 1989 to estimate the abundance and location of cormorants at every known roost in the …
