Examining Risk Factors For Early-Onset Breast Cancer, Jennifer Grace Taylor Jul 2024

Examining Risk Factors For Early-Onset Breast Cancer, Jennifer Grace Taylor

Theses and Dissertations

Introduction: There have been great advancements in screening and in the identifying of risk factors associated with breast cancer, however, there is a lack of information of these factors in women with breast cancer occurring under the age of 45, known as early-onset breast cancer (EOBC). EOBC is often found at later stages, negatively impacting young women’s careers, family planning, and mental health. Additionally, because of the health disparities that exist within the U.S. health care system, women belonging to racial and ethnic groups, specifically young Black women, tend to have poorer outcomes and higher mortality rates of EOBC …

Neutrogeometry And Fractal Geometry, Erick González-Caballero, Maikel Y. Leyva-Vázquez, Noel Batista-Hernández, Florentin Smarandache

Neutrosophic Sets and Systems

Geometries are structures with certain elements like points, lines, planes, and spaces, among others, that satisfy certain definitions, axioms, properties, and theorems for the total of the elements. NeutroGeometries are geometric structures that meet at least one of these concepts only partially, never for 100% or 0% of the elements. Until now, NeutroGeometries have been developed from the ideas of classical geometries such as Euclidean, Hyperbolic, Elliptic, Mixed (Smarandache) geometries, among others where axiomatization is the basis of their construction. This paper aims to discuss some ideas about the relationship between NeutroGeometries and fractal geometry. This relation is not necessarily …

Characterizing The Quorum Sensing (Qs) System In The Model Eukaryote Chlamydomonas Reinhardtii, Kirstin Donnette Cutshaw Jul 2024

Characterizing The Quorum Sensing (Qs) System In The Model Eukaryote Chlamydomonas Reinhardtii, Kirstin Donnette Cutshaw

Theses and Dissertations

Group behaviors in microorganisms are often regulated by low-molecular weight molecules that enable them to sense population density, a signaling system known as quorum sensing (QS). QS in prokaryotes has provided insight into the role ‘social’ behaviors play in the bacterial world and refined our models of virulence, bacterial motility, and more. While less common, similar behaviors are observed in certain fungi, primarily yeasts, in which QS controls cell morphology, biofilm production, and other phenotypes. We have recently pursued the potential for QS to be more broadly distributed among unicellular eukaryotes, which could significantly alter our understanding of social behaviors …

Investigating Microbe-Plant Symbioses In Space, David Handy Jul 2024

Investigating Microbe-Plant Symbioses In Space, David Handy

Theses and Dissertations

As life has evolved on Earth, gravity has been a constant around which biological processes have developed, rather than a pressure that has been adapted to. As humanity ventures into space, we remove this constant and can observe a variety of changes in biological systems, such as bone loss in humans, stunted plant growth, or increased virulence in pathogens. The growing body of data shows that life adapts to spaceflight and microgravity in unique ways that, due to our limited understanding, can be difficult to predict. A particularly under-studied area is that of host-microbe interactions. Despite efforts to limit their …
