Raising Awareness About Recognizing Pediatric Obstructive Sleep Apnea Associated With Down Syndrome: Developing A Health Education Program, Mahima Dave

Undergraduate Student Symposium

Down syndrome (DS) is the most prevalent chromosomal disorder in which an extra copy of chromosome-21 disrupts the development of intellectual abilities. Unique physical manifestations places children with DS at high risk for obstructive sleep apnea (OSA) in which repeated blockages of the upper airway cause difficulty breathing during sleep. 80% of children with DS are afflicted with OSA compared to only 2-5% of the general pediatric population. OSA increases incidences of nocturnal sudden cardiac arrest by 2.57-fold compared to the general population. Common signs of OSA include snoring, restlessness during sleep, night waking, and daytime tiredness. Manifestations of OSA, …

Re-Discovery Of Microatolls In The Galapagos Islands, Ecuador, Amber Orr

Undergraduate Student Symposium

Microatolls are coral colonies with a signature ring-like shape. They form in shallow water where depth limits vertical growth, allowing them to be utilized as indicators of current and past sea level. Additional contributors to their formation include accumulation of sediment on the colonies which smothers corallites in the center of the structure, overgrowth by algae, and upper surface abrasion by bioeroding organisms. Microatolls occur at numerous locations in the Indo-West Pacific, however, they are reported at only two known locations in the tropical eastern Pacific: Caño Island, Costa Rica and the Galápagos Islands, Ecuador. More than 50 Porites lobata …

Skill Football Players Outperform And "Outforce" Big-Skill And Big Players In The Vertical Jump, Jeffrey Marin, Erica Vazquez

Undergraduate Student Symposium

Vertical jump (VJ) performance is critical for football players. Position demands vary and may influence VJ loading (eccentric) and propulsion (concentric) forces. Examining forces in addition to jump height (JH) informs training programs. We aimed to determine differences in VJ performance [reactive strength (RSImod, m/s); JH (cm)] and peack concentric (CON-PF) and eccentric (ECC-PF) forces between position groups. Sixty football players (age, 22.6±1.1yrs; ht, 186.4±6.8cm; mass, 103.6±21.2kg) representing three position groups, Skill, Big-Skill, and Big, performed VJ on dual uniaxial force plates. ForceDecks software allowed for calculation of the dependent variables. ECC-PF and CON-PF were normalized to body mass (N/kg). …

Proton transfer within DNA base pairs is a possible origin for mutations which can ultimately lead to cancer. To better understand this potential source of mutations we have modeled this process using Ab Initio molecular dynamics simulations of model systems for DNA base pairs in water. These simulations have provided insight into how often and when proton transfer occurs in these systems while also highlighting the relationship between the likelihood of a proton transfer event and the way the water molecules are coordinated around the model system for DNA. This in turn has allowed for a greater understanding of potential …

Understanding The Tradeoff Between Atp Metabolism And Growth In E. Coli, Naziba Nuha, Julia Gumirov, Ariane Kalifa

Undergraduate Student Symposium

The inoculum effect (IE) is a phenomenon in which the minimal inhibitory concentration (MIC) of an antibiotic increases with the density of a bacterial population. IE has been observed for nearly all antibiotics, and has been shown to decrease antibiotic efficacy, prolong the recovery period and increase mortality rates. Despite its ubiquity in the clinic, a mechanism to explain IE for bacteria that expresses antibiotic resistant elements, such as β-lactamases, has yet to be identified. Interesting enough, recent work has shown that interactions between growth rate and metabolism, as determined through ATP production, affect IE for bacteria that lack a …

Who Stressed The Dogs Out: A Case For Studying Mitochondrial Dna As A Novel Biomarker For Stress In Canines, Aidan Kunju, Ariana Ali, Ritika Kothur, Olivia Singleton

Undergraduate Student Symposium

Canines transiting through animal shelters experience extreme stress that is subsequently ameliorated by adoption into loving (human) homes. These transitions provide exceptional opportunities to study links between social stress and physiological processes, and to develop biomarkers for stress and social bonding with applications in both animal welfare and human health. Here, we propose a novel approach to the study of shelter-related stress in dogs, and of stress reversals following adoption. Specifically, we will quantify mtDNA dynamics in buccal swabs sampled during shelter intakes of canines at the Broward County animal shelter, as well as samples collected after these animals’ adoptions …

How The Molecular Vibrations Of Water May Prevent Skin Cancer, Ramson Munoz Morales, Jenna Handal

Undergraduate Student Symposium

Studies have shown that when DNA absorbs ultraviolet light it can become structurally damaged leading to a mutation and possibly skin cancer. However, exposing skin to sunlight rarely leads to a mutation. This indicates that after the ultraviolet light is absorbed by the DNA the energy from the light can either cause a structural change to the DNA (a mutation) or be dissipated in a way that does not damage the DNA. Absorption of ultraviolet light causes molecular vibrations in DNA and these vibrations are what likely leads to structural changes in the DNA. One way the structural changes could …
