Factors That Contribute To An Increased Risk For Dental Caries And Prevention Methods, Allen Lee

BIO4960: Practicum in Biology I

This health literacy project focuses on identifying effective strategies for preventing dental caries by analyzing various aspects of an individual’s daily habits. Key lifestyle factors such as sleep patterns, dietary choices, and physical activity were explored in relation to their impact on oral health. The motivation for this project arose from direct observations of the high prevalence of cavities during clinical shadowing experiences, as well as growing evidence in the literature, highlighting an increasing trend in dental caries. Dental caries represent significant public health concern, as untreated caries can lead to serious complications such as tooth abscesses and extractions. Despite …

Embryonic Stem Cell Research, Huda Abu-Suwa, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Stem cell research is a controversial issue that has received considerable attention over the last three decades. Stem cell research began in the early 1980’s, when stem cells were obtained from mice embryos and utilized to understand the functioning of stem cells (Grivennikov, 2008). In 1998, researchers discovered techniques for obtaining embryonic stem cells from human and growing them in laboratories. Since them, substantial research has been conducted on stem cells and their potential uses, which includes increasing our understanding of diseases and how they occur, treating various diseases, and testing new medications for safety and efficacy (Taylor, 2005).

Trace Element Contamination In The Coastal Gray Wolves Of Southeast Alaska, Miranda Brohman

All HCAS Student Capstones, Theses, and Dissertations

Gray wolves (Canis lupus), northern sea otters (Enhydra lutris) and salmon (Oncorhynchus spp.) play vital roles in southeast Alaska, yet all are exposed to trace element (TE) bioaccumulation. This study examines dietary patterns and TE accumulation in four northern Lynn Canal wolf populations (Douglas Island, Juneau, Gustavus, and Pleasant Island) using stable isotope analysis (SIA) (δ¹³C and δ¹⁵N) and TE assessments. SIA revealed that wolves in Juneau and Douglas Island primarily consumed terrestrial prey, whereas wolves in Gustavus and Pleasant Island exhibited enriched isotopic signatures indicative of a marine-based diet, particularly …

The Impact Of Diet On Preeclampsia: An Observational Study Of Nutritional Influence, Trinity G. Moye, Alyssa Cunningham

Department of Nutrition Student Projects

Preeclampsia is a pregnancy-specific condition typically diagnosed after 20 weeks of gestation in women with no prior history of hypertension. Characterized by high blood pressure, proteinuria, thrombocytopenia, increased liver enzymes, and affecting the arteries carrying blood to the placenta, preeclampsia affects the health of both the mother and the fetus. Preeclampsia is disproportionately prevalent in certain populations, specifically among Black women, with various factors contributing to the higher susceptibility including socioeconomic status, education, and health distrust. These factors have been historically structured against Black women in American society. This study aims to reveal how dietary habits can play a role …

The Impact Of Paternal Obesity On Placental Development And Function During Pregnancy, Delaney G. Wolfe, Delaney G. Wiolfe

Department of Nutrition Student Projects

Paternal obesity is a rising concern in conception and reproductive health, with increasing evidence suggesting its impact on pregnancy outcomes. While maternal obesity's effects on fetal development and placental function are well-documented, the role of paternal obesity remains less understood. The placenta, crucial for nutrient exchange and fetal development, can be disrupted by inflammation, oxidative stress, and epigenetic modifications, potentially leading to long-term health implications for both maternal and fetal health. Understanding the paternal influence on placental development is essential for improving pregnancy outcomes and offspring
health. This study aims to investigate the relationship between paternal obesity on placental function …

Salmon As An Ecological Pathway Of Contaminants Into Alaskan Food Webs, Miranda Brohman, Gretchen Roffler, Dimitri G. Giarikos, David Kerstetter, Amy C. Hirons

SECLER Data

Salmon are important fish taxa for humans and animals in hemiboreal and subarctic ecosystems. Trace elements and their marine food web bioaccumulation raises biomagnification and potential human health risk concerns. Sixteen trace element concentrations and their health risk assessments were determined in seven different tissues of two Southeast Alaska salmon species (chum, Oncorhynchus keta and pink, Oncorhynchus gorbuscha). Chum tissues had overall higher trace element concentrations compared to pink, which may be attributed to a difference of diets, generally longer-lived and spending more time in the open ocean. All kidney and liver samples exceeded the tolerable daily intake for …

Retracted: Conserved Domains In Promoters Of Differentially Expressed Genes: How To Find Them And What Can They Tell Us?, Emalynn E. Tobias

Mako: NSU Undergraduate Student Journal

THIS ARTICLE HAS BEEN RETRACTED DUE TO THE FOLLOWING REASON: inadvertent errors in several citations.

The complex process of regulating gene expression involves a large number of cis- and trans-acting components. The cis elements also referred to as cis regulatory elements (CREs) are highly conserved across species, and are often referred to as conserved domains mainly located in the promoters of genes. The trans acting sequences such as enhancers, moderators and insulators are also crucial in the regulation of gene expression. With an increased influx of genomic and transcriptomic data, study of differentially expressed genes (DEGs) is highly effective in …

Resistance Training Versus Cardiovascular Training: Which Is Better For Fat Loss?: A Brief Narrative Review., Jason M. Curtis, Jose Antonio, Cassandra Evans

Journal for Sports Neuroscience

Abstract

Introduction: Obesity has risen from 30.5% to 41.9% from 2000-2017. Those who are considered severely obese increased from 4.7% to 9.2% over that same period. There are numerous fitness-center approaches to induce weight-loss or reduction of body fat. These interventions are often categorized into two general categories: Resistance training (using weighted resistance in anaerobic strength training) and cardiovascular training (aerobic training). While both fitness groups have been shown to be effective, there is a debate about which method is most effective for eliciting changes in body composition, primarily fat loss.

Methods: Google Scholar and Pubmed were scoured for …

Potential Health Risks From Trace Elements In Four Commercially Important Fish Species From The Gulf Of Alaska And Bering Sea Excel Data Sheet, Miranda Brohman, Dimtirios Giarikos, Amy Hirons

SECLER Data

Alaskan waters support a diverse array of fish species that are critical to apex predators and substantial commercial fisheries. Archived white lateral muscle tissue for capelin, herring, walleye pollock, and Pacific cod, from 1993 to 1996 were analyzed for 15 trace elements using induced coupled plasma mass spectrometry. This analysis serves as a proxy for assessing trace element concentrations in the Gulf of Alaska and Bering Sea. The highest concentrations of eight of the 15 elements (cadmium, chromium, cobalt, iron, manganese, selenium, vanadium, and zinc) were found in fish from the central Gulf of Alaska, while capelin showed the …

Ecological Niches Applied To Socioeconomic Phenomena: The Case Of The Colombian Internal Conflict, Alexander Alegría, Laura Jiménez, Jhon Jairo Alvarado-Quintero

Peace and Conflict Studies

Recent studies of the Colombian conflict have shown that struggle for resource accumulation and territorial control, in a very competitive and violent environment in which the illegal armed groups are involved, is crucial to their survival and development. Here, we applied a highly successful methodology from ecology (Ecological Niche Modelling) to the problem of identifying the ideal socioeconomic conditions for the presence of a Colombian illegal armed group, named the Revolutionary Armed Forces of Colombia (FARC). We analyzed some determining factors of FARC´s presence and permanence within the Colombian territory that reflect aspects of the socioeconomic dynamics and productive capacity …

Metabolic Response Of The Code Goby (Gobiosoma Robustum) To Estuarine Climate Change Forecasts, Karli S. Corey

All HCAS Student Capstones, Theses, and Dissertations

Forage fishes are small bodied species that form a diverse functional group, serving as a primary food source for a wide range of marine predators. This group plays a significant ecological role through energy transfer to higher trophic levels. Gobiosoma robustum (Code Goby) is a substantive diet component of several recreationally significant juvenile sportfishes in Florida estuaries. While the thermal tolerance of this species may be inferred from observational data, the absolute physiological limitations of this species remain unknown. In this study, intermittent-flow respirometry and critical thermal maxima were used to determine the response of G. robustum to chronic and …

Spatiotemporal Patterns In Orbicella Faveolata Wound Regeneration As An Indicator Of Colony Health, Alexander G. Wheeler

All HCAS Student Capstones, Theses, and Dissertations

Anthropogenic (e.g. damage from anchors, scuba divers, tissue sampling) and natural disturbances (e.g. predation, storm damage) can result in wounding of live tissue on coral colonies. Wounding has been shown to detract from a common resource pool, increasing disease susceptibility and impairing coral growth and reproductive activity. Regeneration not only varies between species, but also between conspecifics in the same location. A colony’s capacity to regenerate tissue can be an indicator of a colony’s condition and resilience. Understanding the physiological and environmental factors that affect tissue regeneration alongside the ultimate impact of sampling (disease and predation correlations) are needed for …

Species Detection And Discovery Of Zoanthidea Symbiotic With Deep-Sea Gorgonians, Saige Jost

All HCAS Student Capstones, Theses, and Dissertations

Symbiotic marine invertebrates known as Zoanthidea, from the phylum Cnidaria, live on a wide diversity of other organisms. Deep-sea corals such as Gorgonians are one of these clades of hosts. These octocorals and their Zoanthidean symbionts are challenging to collect and consequently difficult to study. However, the Evolution of Marine Symbioses Laboratory at Nova Southeastern University has obtained several samples from the Yale Peabody Museum and other museums or universities with the goal of expanding our knowledge of the diversity of Zoanthideans. Until recently, the existing taxonomic system has been based on morphological characters. A competing molecular parataxonomic system has …

An In-Depth Investigation Into Yersinia Pestis Phages: Isolating A Yersinia Pestis Phage From Soil And Constructing A Comprehensive Phylogenetic Analysis Of Known Yersinia Pestis Phages, Jacqueline Chavez

All HCAS Student Capstones, Theses, and Dissertations

Yersinia pestis, the causative agent of the plague, has become increasingly resistant to many antibiotics; therefore, alternatives such as phage therapy are necessary. Phage therapy uses combinations of bacteriophages or phages, which are viruses that only infect bacteria. However, phages—especially Y. pestis phages —are severely understudied. Thus, this research has sought to specifically isolate a phage from soil that infects Y. pestis. There were 146 samples that were collected from across the US, focusing on those with reported cases of plague. These samples were enriched with Y. pestis to maximize the amount of potential phage that target Y. pestis. …

Comparing Metabolism And Hypoxia Tolerance Of Native And Non-Native Florida Freshwater Fishes In Climate Change Scenarios, Benjamin A. Share

All HCAS Student Capstones, Theses, and Dissertations

As climate change brings rising water temperatures and lower dissolved oxygen (DO) concentrations to freshwater bodies, it has become increasingly important to understand how this will affect ecosystems with established non-native or invasive species. Fishes of the family Cichlidae are the most pervasive non-native fishes in the Everglades and may increase their range further north under a changing climate. To better understand potential invasibility and competition with native fishes, the metabolism and hypoxia tolerance of non-native Blue Tilapia Oreochromis aureus was compared to native Bluegill Lepomis macrochirus when acclimated across a range of seasonal and projected temperatures. Intermittent-flow respirometry was …
