Demystifying Hospital Charges For Hospital Readmissions In 2017 In The United States For Psychoses (Drg = 885), Japjot Singh Apr 2021

Demystifying Hospital Charges For Hospital Readmissions In 2017 In The United States For Psychoses (Drg = 885), Japjot Singh

Undergraduate Student Symposium

Existing research on hospital charges is focused on hospital admissions, but not on hospital readmissions. Literature review on hospital charges identifies several patient-specific, disease-specific, and hospital-specific variables as determinants of hospital charges. Given that there is a relative dearth of similar research focused on hospital readmissions, a federal agency – The Agency for Healthcare Research and Quality (AHRQ) has recognized this gap and developed the Healthcare Cost and Utilization Project (HCUP) in 2015 which contains information on hospital readmissions data. “This database addresses a large gap in healthcare data - the lack of nationally representative information on hospital readmissions.” We …

Drunken Parasites: Morphological Distortions Associated With Chemical Fixatives In Two Monogenetic Flatworms, Wamika Shoukat Apr 2021

Drunken Parasites: Morphological Distortions Associated With Chemical Fixatives In Two Monogenetic Flatworms, Wamika Shoukat

Undergraduate Student Symposium

Fixation is the first step in the identification of animal parasites: its primary purpose is to kill the parasite and prevent or delay decomposition via autolytic enzymes. In the lab, parasitologists typically use ethanol (primarily 70%), formalin, or combinations of the two (e.g. AFA: glacial acetic acid, formalin, and ethanol), but there is little consensus on which best preserves the morphological characters used for parasite identification. Furthermore, parasitologists working in the field and/or internationally are often constrained in their choice of fixative: for example, ethanol can be difficult to obtain in countries that prohibit the sale of alcohol. Instead, various …

Ecological Analyses Of Socio-Economic Food Deserts In Broward County, Annie Goyanes Apr 2021

Ecological Analyses Of Socio-Economic Food Deserts In Broward County, Annie Goyanes

Undergraduate Student Symposium

“Food desert” refers to an area where citizens lack access to fresh, affordable, nutritious food. Food deserts are generally in low-income urban neighborhoods or rural towns and can be considered environmental or economic injustice. South Florida and Broward County have been documented as having a high food insecurity rate, indicative of households having difficulty putting food on the table. Given the high rate of food insecurity, it was hypothesized that a lack of access to food and the presence of socio-economic food deserts was at least partially responsible. Data was collected by visiting three supermarkets in each of the 13 …

Effect Of Saha And Uc2288 On Epithelial To Mesenchymal Transition In P53 Wild/Mutant Types Of Lung Cancer Cells, Tanha Rahman, Naziba Akther Nuha

Undergraduate Student Symposium

Lung cancer is one of the most lethal cancers and encompasses over 30% of cancer-related deaths among men and women globally. Cancer progression is marked by the downregulation of epithelial markers and upregulation of mesenchymal markers, which causes solid tumors to become malignant and increase their invasiveness and metastatic properties. The epithelial-mesenchymal transition (EMT) is facilitated through complex molecular pathways that include epigenetic and posttranslational modifications. In this regard, DNA as well as Histone methyltransferases are suspected to be involved within the EMT process. In our study, we analyzed the markers of EMT in H460 and HCC827 lung cancer cells …

English Language Proficiency And Overall Verbal Ability: A Comparison Between Bilingual And Monolingual College Students, Samruddhi Ayachit, Erika Cabrera Ranaldi Apr 2021

English Language Proficiency And Overall Verbal Ability: A Comparison Between Bilingual And Monolingual College Students, Samruddhi Ayachit, Erika Cabrera Ranaldi

Undergraduate Student Symposium

Assessment of linguistic abilities of non-native English speakers reveals that Spanish/English bilinguals do not perform as well as English monolinguals on tests that require naming of common objects. Similarly, tests of English language proficiency reveal weaker performance in Spanish/English bilingual groups relative to monolinguals. One important limitation of some of these studies is that the language groups are different on educational attainment, which impacts linguistic abilities. Moreover, there are few studies evaluating overall verbal ability in these linguistically diverse groups. To fill these gaps in the research, we tested English monolingual (n=109) and Spanish/English bilingual (n=152) college students with similar …

Influence Of Growth Efficiency, Bacterial Density, And Metabolism On Antibiotic Resistance Across Different Drug Classes, Gabriela Diaz Tang, Estefania Marin Meneses Apr 2021

Influence Of Growth Efficiency, Bacterial Density, And Metabolism On Antibiotic Resistance Across Different Drug Classes, Gabriela Diaz Tang, Estefania Marin Meneses

Undergraduate Student Symposium

Antibiotic resistance has become a prevailing issue in the health care system due to increased hospital costs and mortality. Moreover, the discovery of new antibiotics has slowed significantly. Thus, there is a dire need to understand the general mechanisms by which bacteria resist antibiotics towards extending the usefulness of existing drugs. Recently, the effect of metabolism on drug efficiency has revealed that when bacterial metabolism is more active, antibiotics become more lethal. Accordingly, we chose to study how the inoculum effect, where the initial density of bacteria determines the minimum inhibitory concentration (MIC) of drug required, is impacted by bacterial …

Interlimb And Intralimb Coordination During Speed Running In American Football Players Training For The Nfl Draft, Emily Udvardy, Madison Allen Apr 2021

Interlimb And Intralimb Coordination During Speed Running In American Football Players Training For The Nfl Draft, Emily Udvardy, Madison Allen

Undergraduate Student Symposium

Speed is integral to players seeking to be drafted into the National Football League (NFL). To increase speed, coaches promote running symmetry and coordination. Coordination during running is assessed by graphing the relative temporal and spatial patterns of the hip, knee, and ankle, and visually inspecting the resulting angle-angle plots for linearity (in-phase, anti-phase, decoupled). Though qualitative, this method is sophisticated as it examines movement patterns versus discrete points. Therefore, we sought to describe intralimb and interlimb coordination during speed running in elite American football players undergoing a 6-week NFL draft preparation camp. Twelve participants (age, 21.8±0.8 yrs; ht, 1.8±0.05 …

Investigating Differences In Eye-Movement Between Children With Asd And Children With Neurotypical Development, Sruthi Kundur Apr 2021

Investigating Differences In Eye-Movement Between Children With Asd And Children With Neurotypical Development, Sruthi Kundur

Undergraduate Student Symposium

Children with Autism Spectrum Disorders (ASD) have deficits in social skills; nonetheless, research suggests that a pet can help reduce stress and negative outcomes. Evidence from the literature suggests that there is a correlation between the ability to demonstrate emotion and the ability to understand other’s intentions in order to make the correct assumptions. However, children with ASD lack the ability to understand social cues and make better predictions. This study investigates the eye movement of children with ASD in comparison to children with neurotypical development. Eye-tracking data, including heat maps and eye-movement time-lapses were collected from children with ASD …

Mindfulness Training During A Pandemic: Can Online Mindfulness Training Reduce Distress?, Aysha D. Patel, Catherine Weber, Mamiko Swanson, Sharan Sankar Apr 2021

Mindfulness Training During A Pandemic: Can Online Mindfulness Training Reduce Distress?, Aysha D. Patel, Catherine Weber, Mamiko Swanson, Sharan Sankar

Undergraduate Student Symposium

The COVID-19 pandemic has resulted in a number of negative outcomes, including economic, psychological, and physical health concerns (Gruber et al., 2020; Fine, Reichle, & Lord, 2020). Levels of depressive symptoms and anxiety have appeared to be higher during the pandemic than they were prior to the pandemic (O’Connor et al. 2020). Mindfulness meditation training has been shown to reduce the impact of stress on cognitive functioning and anxiety. Reductions in depressive symptomatology have also been shown to occur following mindfulness training. Although mindfulness-based interventions often consist of eight weeks of training with one weekly in-person session, the current study …

Minor Changes With Large Implications: Modeling Amino Acid Mutations In Sars-Cov Monoclonal Antibodies (80r And 362) Towards The Design Of More Universal Antibodies, Christo Manikkuttiyil, Carolina Alzamora, Carol Manikkuttiyil

Undergraduate Student Symposium

SARS-CoV-2, the causative agent of COVID-19, has led to over 100 million cases and over 2 million deaths worldwide. Two anti-SARS-CoV monoclonal antibodies (MAbs) 80R and 362 are known to bind to epitopes on the spike protein receptor-binding domain (RBD), with 80R binding to SARS-CoV-1 and 362 binding to both SARS-CoV-1 and SARS-CoV-2. To investigate this further and hypothesize structures for a potentially more effective antibody, undergraduate students participated in the CREST (Connecting Researchers, Educators, and STudents) Program and studied the binding interactions between the antibodies and their respective spike proteins. At the binding interface between these antibodies and the …

Numerical Representation Of Amino Acid Sequences, Naziba Akther Nuha Apr 2021

Numerical Representation Of Amino Acid Sequences, Naziba Akther Nuha

Undergraduate Student Symposium

Amino acid substitution matrices attempt to quantify the rates at which the different amino acid residues in proteins are functionally substituted by other amino acid residues with similar biochemical properties. Currently, the most widely utilized substitution matrices comprise BLOSUM-62, PAM-120 and PAM250 among others. Percent recognized mutation (PAM) matrices list the probability of transition from one amino acid to another during evolution of homologous protein sequences and are therefore based on monitoring protein evolutionary origins. In comparison, the amino acid substitution matrices of the blocks (BLOSUM) are based on scoring substitutions observed over a number of cycles of evolution. Traditionally, …

Periodically Distrubing The Spatial Structure Of A Microbial Community Composed Of Pseudomonas Aeruginosa And Staphylococcus Aureus Determines Its Composition, Camryn Pajon, Brandon Toscan, Taniya Mariah Apr 2021

Periodically Distrubing The Spatial Structure Of A Microbial Community Composed Of Pseudomonas Aeruginosa And Staphylococcus Aureus Determines Its Composition, Camryn Pajon, Brandon Toscan, Taniya Mariah

Undergraduate Student Symposium

Pseudomonas aeruginosa and Staphylococcus aureus can co-occur in chronic and hard-to-treat infections. They interact through several small diffusible molecules and enzymes which increase their virulence, growth rates, and antibiotic resistance. Previous work has shown that the spatial structure of microbial communities in continuously mixed environments and completely undisturbed environments affects bacterial interactions. These extreme cases fail to fully represent a natural environment where the spatial structures developed by the microbes are periodically disturbed. The objective of this study is to determine how periodic perturbations to spatial structures affects the interaction and co-existence of P. aeruginosa and S. aureus in co-culture. …

Propofol And The Renin-Angiotensin System, Giovanna Gnozzo Apr 2021

Propofol And The Renin-Angiotensin System, Giovanna Gnozzo

Undergraduate Student Symposium

The renin-angiotensin system (RAS) has become a more popular subject of research due to its role in regulating homeostasis within the body as a whole, and regulation of cerebral blood flow, memory consolidation, and etiology of various neurological diseases within the local nervous system RAS. The main effector of the system is Angiotensin (Ang) II, through the activation of the AT1 or AT2 receptor subtypes. Overactivation of the AT1 subtype leads to inflammation and hypertension within the body and an increase in neuronal apoptosis and oxidative stress within the nervous system. Propofol, a commonly used anesthetic in general surgery, has …

The Relationship Between Covid-19 Social Distancing And Feelings Of Anxiety And Depression In The United States, Rahul Gorijavolu Apr 2021

The Relationship Between Covid-19 Social Distancing And Feelings Of Anxiety And Depression In The United States, Rahul Gorijavolu

Undergraduate Student Symposium

Efforts to control the spread of COVID-19 has included mandatory curfews, quarantine, and social distancing policies enacted by government officials across the United States. These changes can result in feelings of loneliness, fear, and isolation. Healthcare workers and individuals with a history of psychiatric illness are more likely to develop anxiety and PTSD during quarantine due to COVID-19 (Brooks, 2020). Research conducted during the Middle East Respiratory Syndrome (MERS) outbreak of 2015 found that people forced to quarantine experienced increased anxiety and feelings of anger, which subsequently decreased four to six months after the period of isolation ended (Jeong, 2016). …

Understanding Metabolic Activity During The Inoculum Effect, Kavish Patel, Vijay Patel, David Singh, Abhishek Venkataramnan Apr 2021

Understanding Metabolic Activity During The Inoculum Effect, Kavish Patel, Vijay Patel, David Singh, Abhishek Venkataramnan

Undergraduate Student Symposium

With the post antibiotic era upon us, new techniques are required to treat bacterial infections. While the mechanisms of acquired resistance to antibiotics are well studied, mechanisms by which bacteria can resist antibiotics in the absence of acquired resistance are less studied. This is called phenotypic resistance. One form of phenotypic resistance is the inoculum effect (IE) where the initial density of a bacterial population determines the minimum inhibitory concentration (MIC) of an antibiotic. Given recent findings showing that the metabolic rate of bacteria determines its susceptibility to antibiotics, we sought to understand how changes to metabolism and growth determined …

Utilitarian Perspective On Genetic Enhancement, Varun Kota Apr 2021

Utilitarian Perspective On Genetic Enhancement, Varun Kota

Undergraduate Student Symposium

The invention of CRISPR-CAS9 allows one to edit the genome easily. As a result, many are excited by the potential breakthroughs in medical applications. Others worry that the development of this technology will lead to genetic enhancement, the modification of a set of genes toward a non-therapeutic end goal. After reviewing the philosophical and ethical literature regarding genetic enhancement it became apparent that there was a lack of specificity. Often, the arguments portrayed genetic enhancement as a fantastical process. In reality, the effects of genetic enhancement are far tamer. The folly in these discussions lies in the notion that traits …

Characterizing The Mechanism Of Inhibition Displayed By Imidocarb Dipropionate On Yersinia Pestis, Sukriti Prashar

Undergraduate Student Symposium

With the growing antibiotic resistance crisis, there is a need for development of new antibiotics. Several antibiotic resistant, gram-negative bacteria employ a type III secretion system (T3SS) making it an attractive target for new drugs. The T3SS is a multi-protein complex organized in a needle-like structure used to inject host cells with effector proteins to cause infection. Imidocarb dipropionate is a known inhibitor of the T3SS of Yersinia pestis, the causative agent of the bubonic plague, however its mechanism of inhibition is unclear. The purpose of this research was to determine which protein of the T3SS of Y. pestis …

Forces Affecting Genital Morphology Of Eastern Mosquitofish In The Everglades, Dyane Oliva, Rose Leeger, Caila Guzman Nunez Apr 2021

Forces Affecting Genital Morphology Of Eastern Mosquitofish In The Everglades, Dyane Oliva, Rose Leeger, Caila Guzman Nunez

Undergraduate Student Symposium

Eastern Mosquitofish are abundant fish in the Everglades. Some of their populations make annual, long distance migrations into temporary wetlands that dry out every year. Past work indicates differences in migration ability among fish from wetlands of different hydroperiod. Eastern Mosquitofish internally fertilize with a modified fin that acts as a penis-like “gonopodium,” which has been shown in other mosquitofish species to respond to the presence or absence of predators via altered size and shape. Data collected in 2019 reveals variation in gonopodium size and shape for Eastern Mosquitofish in Everglades wetlands that dry annually when compared to those from …
