A Text-Based Smoking Cessation Intervention For Sexual And Gender Minority Groups: Protocol For A Feasibility Trial, Irene Tami-Maury, Rebecca Klaff, Allison Hussin, Nathan Grant Smith, Shine Chang, Lorna Mcneill, Lorraine R Reitzel, Sanjay Shete, Lorien C Abroms

Faculty, Staff and Student Publications

BACKGROUND: Smoking among sexual and gender minority (SGM) groups, which include lesbian, gay, bisexual, transgender, and queer individuals, has been reported to be highly prevalent. This is attributed to several factors, including minority-specific stress and targeted tobacco marketing. Therefore, this population is at an increased risk for tobacco-related diseases. SMS text messaging programs have been found to be effective for smoking cessation and appeal to traditionally hard-to-reach populations over other interventions. It has also been suggested that targeted and tailored interventions could be more effective among SGM smokers because they can be designed to assure a safe, validating health care …

School of Medicine Faculty Publications

An association between the BRAFV600E mutation and the clinicopathological progression of papillary thyroid microcarcinoma (PTMC) has been suggested. We aimed to summarize the relevant literature and determine the predictive value of BRAFV600E mutation in predicting clinical outcomes and risk stratification in patients with PTMC. A systematic search using PubMed, Cochrane, and Embase up to February 2020 was performed. A total of 33 studies met the inclusion criteria, resulting in a pool of 8838 patients, of whom 5043 (57.1%) patients were positive for BRAFV600E mutation. Tumors with positive BRAFV600E mutation had a higher tendency for multifocality (RR = 1.09, 95%CI = …

Alterations In The Oral Microbiome Leading To Inflammatory Periodontal Disease, Emma Vlaun

Honors Scholar Theses

The oral cavity contains a complex micro-ecosystem of flora inhabiting a variety of different niches. Some of these niches include saliva, shedding surfaces, and non-shedding surfaces. Biofilms in the oral microbiome, colloquially referred to as dental plaque, can accumulate on non-shedding surfaces, such as natural teeth and other artificial hard parts such as braces, dentures, fillings, and implants. These biofilms are made up of many mutualistic bacteria that stick to each other and adhere to hard surfaces. Scientists speculate that at least 700 different species of bacteria inhabit various parts of the mouth. These bacteria occupy different niches in varying …

Preeclampsia is a complex disease of pregnancy whose physiopathology remains unclear. We developed machine-learning models for early prediction of preeclampsia (first 16 weeks of pregnancy) and over gestation by analyzing six omics datasets from a longitudinal cohort of pregnant women. For early pregnancy, a prediction model using nine urine metabolites had the highest accuracy and was validated on an independent cohort (area under the receiver-operating characteristic curve [AUC] = 0.88, 95% confidence interval [CI] [0.76, 0.99] cross-validated; AUC = 0.83, 95% CI [0.62,1] validated). Univariate analysis demonstrated statistical significance of identified metabolites. An integrated multiomics model further improved accuracy (AUC …

Gender Identity, Sports, And Affirmative Action: What's Title Ix Got To Do With It?, Michael E. Rosman

St. Mary's Law Journal

There is much talk these days of promoting “equity” rather than “equality.” When applied outside athletics, Title IX promotes non-discrimination, usually associated with equality. As it has been applied to sports, though, it may be our most prominent “equity” statute, making sure each sex gets its fair share.

The questions this article seeks to address are legal ones that the debate about trans females seems to bring to the fore. How did we start with a statute whose language looks very similar to every other civil rights statute—and, indeed, that acts just like every other civil rights statute outside of …

Food Insecurity Among College Students: Perception Of College Administrators, Ibiyemi Adesanya

Seton Hall University Dissertations and Theses (ETDs)

Abstract

While food insecurity among college students has existed for decades, only in recent years has the focus on the impact of food insecurity on student success emerged. However, most of the research has been quantitative, conducted at public two-year and four-year colleges and focused on predictors, prevalence, and impact of food insecurity among college students. Although prior student-based research has been beneficial to understand the problem, there is inconsistency in how institutions and higher education professionals address this issue with their students.

A transcendental phenomenological single case study design was used in this study to explore the lived experience …

Development Of A Crosslinked Osteochondral Xenograft And A Collagen Stabilizing Intra-Articular Injection To Remediate Cartilage Focal Lesions To Prevent Osteoarthritis, Mark Lewis Mosher

Theses and Dissertations

Osteoarthritis is one of the most common causes of disability in adults in America. It is a progressive and degenerative disease where the articular cartilage is broken down and lost from the surfaces of bones causing chronic pain and swelling in the joints, and currently has no cure. The most commonly osteoarthritis starts from a focal lesion on the cartilage surface, which will expand on the surface and downwards through the thickness of the tissue. The current gold standard for correcting cartilage focal lesions is the osteochondral autograft/allograft transplantation (OAT), which replaces the defect with a fresh osteochondral graft. The …

Beyond All Worlds: George Macdonald, The Pre-Tolkienians, And The Forgotten Possibilities Of Fantasy, Ethan Patrick Stevens

Masters Theses

The history of modern fantasy has been powerfully shaped by the worldbuilding paradigm so successfully executed in J.R.R. Tolkien's 1954-55 trilogy The Lord of the Rings. However, there were nearly a hundred and fifty years of creative work between the birth of fantasy as a genre and Tolkien’s publication of The Lord of the Rings. By examining the pre-Tolkienian fantasists, we find that Tolkien's way of exhaustive consistency was not, and is not, the only way to write fantasy. Phantastes (1858), the first novel by the influential Victorian fantasist George MacDonald, defies contemporary worldbuilding standards almost constantly in …

Insights Into Early-Stage Inbreeding Depression In Hawaiian Metrosideros, Rosalie Chaleunsouck

Undergraduate Research Symposium Podium Presentations

Inbreeding depression is the reduced biological fitness of offspring resulting from the conception of two genetically related gametes. Selfing, the fusion of gametes from the same individual, is the most extreme form of inbreeding, common in many plant species. Inbreeding depression is most prevalently seen at the seed-development stage (Levin, 1981).

Assessing The Legacy Of Erosion And Flood Control Management Efforts On The Fish Assemblages And Physical Conditions Of Yazoo Basin Bluff Hill Streams, Nicky M. Faucheux

Theses and Dissertations

The hills of Yazoo Basin have a long history of land use modification and subsequent erosion and flood control issues. In response, federal actions were taken to address these issues beginning after the Mississippi River flood of 1927. Four major flood control reservoirs were built in 1932-1957, and instream low-drop grade control structures (GCS) were installed beginning in the 1980s. The objective of my dissertation was to ascertain the long-term effects of these efforts on stream fish assemblages and channel morphology. To assess whether the reservoirs affected upstream fish assemblages as barriers to recolonization by fluvial fishes or as source …

Towards Structured Planning And Learning At The State Fisheries Agency Scale, Caleb A. Aldridge

Theses and Dissertations

Inland recreational fisheries has grown philosophically and scientifically to consider economic and sociopolitical aspects (non-biological) in addition to the biological. However, integrating biological and non-biological aspects of inland fisheries has been challenging. Thus, an opportunity exists to develop approaches and tools which operationalize planning and decision-making processes which include biological and non-biological aspects of a fishery. This dissertation expands the idea that a core set of goals and objectives is shared among and within inland fisheries agencies; that many routine operations of inland fisheries managers can be regimented or standardized; and the novel concept that current information and operations can …

Effects Of Post-Fire Disturbance Responses Of Microstegium Vimineum On Native Hardwood Seedling Growth And Survival, Zachary A. Chandler

Theses and Dissertations

Invasions by alien understory plant species have gradually become a worldwide challenge in maintaining forest biodiversity and ecosystem productivity. Notably, Microstegium vimineum, a C4 grass native to Japan, has increased dominance in mixed deciduous hardwood forests of the southeastern United States, largely due to its shade tolerance and ability to spread through rhizomes. Microstegium vimineum also proliferates after prescribed fire, a common management tool used in the region to restore forests to desired conditions, and may compete with hardwood seedlings, hindering restoration efforts. Using two upland deciduous hardwood forest research sites in Marshall and Tate Counties, Mississippi, this study …

Non-Traditional Adjuvants And Methods For Applying Root-Promoting Compounds In Commercial Cutting Propagation, Anthony Turner Bowden

Theses and Dissertations

The nursery/greenhouse industry is innovative. There have been several reports in the popular literature of non-traditional adjuvants used in plant propagation; however, these claims have never been evaluated in a scientific setting. Five studies, conducted at the South Mississippi Branch Experiment Station in Poplarville in 2019 and 2021 determined the impact that adding honey to water-soluble auxin solutions and surfactants to foliar applied auxin solutions on physiological responses associated with adventitious root formation. Treatments in studies presented in chapters two and three included three honey sources (multiflora, local, and Manuka). Honey-infused water-soluble auxin solutions affected plant species but not in …

Development Of A Novel Loop-Mediated Isothermal Amplification (Lamp) Assay For The Rapid Detection Of Clostridium Perfringens, Deepa Chaudhary

Theses and Dissertations

Clostridium perfringens (C. perfringens) causes diseases such as necrotic enteritis in poultry. Current methods for early detection of C. perfringens, including culture, and molecular techniques (PCR and qPCR), have logistical limitations in detecting pathogens on-site because they require specialized equipment and long sample preparation time. This study describes developing a highly sensitive on-site LAMP assay combined with a simple DNA extraction method to detect C. perfringens. Results showed that the LAMP assay was highly specific and sensitive with the optimal reaction conditions: 63°C for 30 mins with primer concentration of 1.2 mM FIP/BIP and 0.2 mM F3/B3. The HotSHOT method …

Microstructure And Sensory Attributes Of Rabbiteye Blueberries Subject To Osmotic Dehydration And Two Freezing Methods, Antonio Carlos Garcia

Theses and Dissertations

Frozen, thawed and osmotically-dehydrated highbush (HB) (Vaccinium corymbosum) and rabbiteye (RB) (V. virgatum) blueberries were analyzed under a scanning electron microscope (SEM) to observe microstructural differences in their skin. Rabbiteye blueberries of both frozen, thawed and osmotically-dehydrated treatments, had thicker skins than highbush blueberries. Rabbiteye blueberries, collected from local farms, packed and blast frozen (PBF), had thinner skins than individually quick-frozen (IQF) blueberries. Washing berries prior to freezing had no effect on skin thickness. Sensory analysis of samples determined there were no differences (p > 0.05) between PBF and IQF methods and species with respect to skin intactness, grittiness, sweetness, and …
