Bridging The Gap: Reducing Disparities In Reproductive Healthcare For Black And White Women, Emma Weiden

Population Health Research Brief Series

A woman’s reproductive healthcare experience in the United States can vary dramatically depending on her race. In 2020, the pregnancy-related mortality rate in the U.S. was 40.8 deaths per 100,000 live births for Black women, which is more than three times the rate among White women (12.7 per 100,000). This brief summarizes disparities in reproductive healthcare outcomes for Black women compared to White women in the U.S., advocates for policy changes, and provides recommendations for addressing racial disparities to create more equitable reproductive healthcare.

Presever, $N$-Potent, And Periodic Operators On Banach Spaces And Function Spaces, Zachary Easley

Electronic Theses and Dissertations Archive

In this thesis, we investigate certain ``preserver operators" from one Banach space into another. ``Preserver operators" are operators that leave unchanged one or more important properties of the domain space of the operator. Additionally, we explore operators related to or built from these preserver operators. Of importance will be the preserver operator known as an ``isometry," which are ``norm-persevering" operators, and the ``spectral projections" constructed from the elements contained in the spectrum of the isometry. The main results of this dissertation focus on projections (and more generally, $n$-potent operators) in the convex hull of a subgroup of the group of …

Olin, Katelyn J. Lamb, Michael J. Polito, Nancy N. Rabalais, Brian J. Roberts, Erick M. Swenson, Olaf P. Jensen

Michigan Tech Publications

Advancing ecological restoration assessments requires a more detailed consideration of species interactions and ecosystem processes. Most restoration projects rely on a few metrics not always directly linked with ecological theory. Here, we used Odum's theory of ecosystem development to assess and compare the ecosystem structure and services of created marshes (4–6 years old) with preexisting, reference marshes in a brackish water region of the Mississippi River Delta. We built ecosystem models for created and reference marshes that integrated large datasets of stomach contents, stable isotopes, and taxa abundances. Despite strong resemblance in community structure, created marshes were at an earlier …

In The Hot Seat: Acquiring Kernel Density Heat Map Design Guidance Through Delphi And Survey Methods, Lauren Eileen Mckinney-Wise

Dissertations and Theses

Kernel density heat maps have emerged as a new, popular thematic map type. Yet, unlike other thematic map types, little if any published guidance exists for effective heat map design. This is significant because maps are highly persuasive objects that are often utilized to communicate important information, but maps can also be misleading and misunderstood. Therefore, proper guidance for heat map creation is critical for cartographers to create maps that convey geographic information successfully.

To address this literature gap, I used a modified Delphi method and an online survey to investigate several questions, including understanding what cartographic experts think are …

Evaluating The Efficacy Of A Thermoresponsive Hydrogel For Delivering Anti-Collagen Antibodies To Reduce Posttraumatic Scarring In Orthopedic Tissues., Andrzej Steplewski, Jolanta Fertala, Lan Cheng, Mark Wang, Michael Rivlin, Pedro K Beredjiklian, Andrzej Fertala

Department of Orthopaedic Surgery Faculty Papers

Excessive posttraumatic scarring in orthopedic tissues, such as joint capsules, ligaments, tendons, muscles, and peripheral nerves, presents a significant medical problem, resulting in pain, restricted joint mobility, and impaired musculoskeletal function. Current treatments for excessive scarring are often ineffective and require the surgical removal of fibrotic tissue, which can aggravate the problem. The primary component of orthopedic scars is collagen I-rich fibrils. Our research team has developed a monoclonal anti-collagen antibody (ACA) that alleviates posttraumatic scarring by inhibiting collagen fibril formation. We previously established the safety and efficacy of ACA in a rabbit-based arthrofibrosis model. In this study, we evaluate …

The Aesthetics Of Social Innovation: The Body As The Site Of Change, Amy Phillips

Masters Projects

Social innovation scholarship often prioritizes tangible, product-based answers to questions of societal justice without examining the catalyst for change. Exploring the potential of the body to serve as a site of social innovation may complement the goals of emerging paradigms of social innovation that embrace new forms of knowing. The sensory knowledge developed through methods such as Augusto Boal’s Theatre of the Oppressed is systematized in the multidisciplinary field of somaesthetics, which looks closely at the disciplined cultivation of the body. This research project tracked the perceived body awareness and self-growth of formerly incarcerated individuals following four applied theatre workshops. …

Oral Small Molecule Agents In Management Of Ulcerative Colitis: Fact Or Fancy, Benan Kasapoğlu, Ati̇lla Ertan

Turkish Journal of Medical Sciences

Ulcerative colitis is a chronic, immune-mediated disease characterized by recurring episodes of mucosal inflammation in the colon and rectum. The primary pathogenic mechanism of ulcerative colitis is the dysregulation of the mucosal immune response. The disease follows a relapsing-remitting course, and the goal of management is to successfully induce and then maintain remission. Effectively managing this chronic disease requires addressing all aspects of it. Currently, we have various antitumor necrosis factor agents and novel biologics available for treating ulcerative colitis patients with moderate-to-severe disease. However, none of the existing treatments are considered entirely satisfactory or ideal in these cases. After …

Long Noncoding Rnas In Pancreas Cancer: From Biomarkers To Therapeutic Targets, Esra Güzel Tanoğlu, Seyfure Adigüzel, Alpaslan Tanoğlu, Zehra Betül Aydin, Güli̇zar Hocaoğlu, Samet Ebi̇nç

Turkish Journal of Medical Sciences

Long noncoding RNAs (lncRNAs) are noncoding RNA molecules with a heterogeneous structure consisting of 200 or more nucleotides. Because these noncoding RNAs are transcribed by RNA polymerase II, they have properties similar to messenger RNA (mRNA). Contrary to popular belief, the term "ncRNA" originated before the discovery of microRNAs. LncRNA genes are more numerous than protein-coding genes. They are the focus of current molecular research because of their pivotal roles in cancer-related processes such as cell proliferation, differentiation, and migration. The incidence of pancreatic cancer (PC) is increasing around the world and research on the molecular aspects of PC are …

Evaluation Of The Cytotoxic Effect Of Titanium Dioxide Nanoparticles In Human Embryonic Lung Cells, Olkan Afşar, Çağatay Oltulu

Turkish Journal of Medical Sciences

Background/aim: Titanium dioxide nanoparticles are widely used in a variety of products, including sunscreens, paints, and ceramics. However, their increasing use has raised concerns about their potential health risks. Titanium dioxide nanoparticles have been shown to have the ability to enter the bloodstream and accumulate in various tissues, reaching the fetus via the placenta. The aim of this study was to investigate the cytotoxic effects of titanium dioxide nanoparticles on a human embryonic lung cell line (HEL 299/An1) and the formation of oxidative DNA damage. Materials and methods: The cytotoxic effects of brookite-based titanium dioxide nanoparticles (<100 nm) were assessed using the 3-(4,5-dimethyldiazol-2-yl)-2,5 diphenyl tetrazolium bromide (MTT) assay for 24 and 48 h. Cell titanium levels were determined using inductively coupled plasma mass spectrometry. Oxidative DNA damage was assessed by measuring the levels of 8-hydroxy-2- deoxyguanosine (8-OHdG) as a biomarker. Results: Titanium dioxide nanoparticles caused dose-dependent cytotoxicity in HEL 299/An1 cells. The IC50 values were 25.93 μM and 0.054 μM after 24 h and 48 h of exposure, respectively. Cell titanium levels were found to be 25,967 ppb after 24 h and 210,353 ppb after 48 h (p < 0.01). 8-OHdG was detected at 32.96 ng/mL after 24 h of exposure and 17.89 ng/mL after 48 h of exposure. Conclusion: In our study, it was shown that titanium nanoparticles caused dose-dependent cytotoxicity and oxidative DNA damage in human embryonic lung cells. The nanoparticles also accumulated in cells and were taken up in higher amounts after 48 h of exposure. These findings suggest that titanium dioxide nanoparticles may pose a health risk, especially for pregnant women who may not be aware of their pregnancy. Therefore, it is important to take preventive measures to reduce exposure to these nanoparticles.
