Purification Of Recombinant E. Coli Topoisomerase Iii For Structure-Based Drug Design Using Protein Crystallization, Miguel A. Perez Rodriguez, Yuk-Ching Tse-Dinh

FIU Undergraduate Research Journal

Type IA Topoisomerases are ubiquitous enzymes found throughout all life forms and species. These topoisomerases relieve the topographical constrains formed by DNA during processes like replication and transcription via a cleavage-religation mechanism performed through a catalytically active tyrosine residue in the primary structure of the enzyme. E. coli Topoisomerase III (EtopIII) is a type of Type IA topoisomerase, and its main function in the cell is as a decatenase, which means that it unlinks circular or intertwined pieces of genetic material and creates two unlinked segments of DNA from a singular linked chain. Structure-based determination of the enzyme’s three-dimensional structure …

Validation Of A Forensic Method To Be Used In Food Fraud Investigation, Jennifer Melayes, Nicole Deangelo, Vallarie Ostenson, Fabiana Taglia Dr., Deetta Kay Mills Dr.

FIU Undergraduate Research Journal

Food fraud is the act in which food is purposefully mislabeled, adulterated, or contaminated, often to make up a percentage of a missing substance when the product is being made. It is often done purposefully to mislead consumers into thinking some ingredient is or is not present in the food, which can be hazardous to the consumer. This project aimed to validate a forensic domestic animal species reference ladder and multiplex PCR kit that can be used in animal investigations, with a focus on food fraud. A multiplex PCR protocol targeting mitochondrial DNA (mtDNA) markers and a species reference ladder …

The Evolution Of Tumor Suppressing Genes In Multicellular Organisms: Nature’S Prevention Of Oncogenesis, Melanie Perez

FIU Undergraduate Research Journal

The p53 gene family, a well-known group of genes, is the primary propagator of tumor-suppressing mechanisms in multicellular organisms. Although they are currently critical drug targets in cancer, the p53 family also serves specific functions in the development of multicellular organisms. In this paper, the current function, origin, and evolutionary purpose of the p53 family are reviewed in the evolution of multicellular organisms. The TP53 gene induces cellular responses such as apoptosis as a way to combat detrimental environmental and cellular factors that can damage the integrity of a cell’s DNA. The other two members of the p53 family are …

Constructible Sandwich Cut, Philip A. Son

FIU Undergraduate Research Journal

In mathematical measure theory, the “Ham-Sandwich” theorem states that any n objects in an n-dimensional Euclidean space can be simultaneously divided in half with a single cut by an (n-1)-dimensional hyperplane. While it guarantees its existence, the theorem does not provide a way of finding this halving hyperplane, as it is only an existence result. In this paper, we look at the problem in dimension 2, more in the style of Euclid and the antique Greeks, that is from a constructible point of view, with straight edge and compass. For two arbitrary regions in the plane, there is certainly no …

The Effect Of Saltwater Stress On The Performance Of Cherry Tomatoes, Samarah R. Martin, Ivan Oyege, Kateel G. Shetty, Krish Jayachandran, Maruthi Sridhar Balaji Bhaskar

FIU Undergraduate Research Journal

Rising sea levels and saltwater intrusion in aquifers pose significant challenges for South Florida agriculture, leading to increased groundwater salinity and potential crop losses. Utilizing salttolerant crop species presents a potential solution for saline soils and regions with active saltwater intrusion. However, the effects of soil salinization through groundwater alone remains less studied. This research investigates the impact of short-term, below-ground saltwater stress on the growth, survival, and overall health of commonly grown cherry tomatoes (Solanum lycopersicum). The objectives of the study are to: 1) determine the impact of saline groundwater on tomato plant health and 2) compare the nutrient …

Exploring The Evolution Of Gender-Based Violence In India And Its Contributing Actors, Angel E. Reji

FIU Undergraduate Research Journal

Violence against women is an issue worldwide; however, this paper focuses on India, where women are at greater risk of becoming victims of violence from a range of perpetrators - including their own families, to a certain extent. Although there are various forms of violence, dowry-related domestic violence and rape are comparatively abundant, especially in coverage in the Indian news media. Despite the first feminist efforts against the violence and degradation of women nearly 50 years ago, there have yet to be any substantial changes. Throughout the history of the subcontinent — first as the Indus Valley civilization and later …

The Impacts Of The Low-Fodmap Diet On The Management Of Irritable Bowel Syndrome Symptoms: Possibilities, Feasibility, And Alternatives, Nicolas J. Jo, Carmen Ortega-Santos

FIU Undergraduate Research Journal

Irritable bowel syndrome (IBS) is a common gastrointestinal (GI) condition characterized by a myriad of GI symptoms (e.g., diarrhea, nutrient malabsorption) that vary in severity. Due to its complex and individual nature, there is no known cure for IBS, but many diets have been assessed for their viability in managing symptoms. The low-FODMAP diet has recently been investigated for its potential benefits for IBS patients. FODMAPs, or Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols are short- and medium-chain carbohydrates that are poorly absorbed in the small intestine and are prone to absorb water and ferment in the colon. Consumption of these …

An Examination Of The Ways In Which Transdisciplinary Research Could Be Used To Incentivize Local Communities To Combat The Illegal Wildlife Trade, Jessica Rios

FIU Undergraduate Research Journal

The illegal wildlife trade (IWT) is currently one of the most critical conservation concerns, given its direct impact on biodiversity loss, endangering local ecosystems, and adding pressure to all species at a point when they face dangers like deforestation and mass extinctions. This industry also significantly impacts local communities, many of which are compelled to engage in it as a result of their precarious socioeconomic conditions. While effective countermeasures to this global issue have been identified, successful implementation of these countermeasures require diverse disciplines and collaborators. This paper argues that a transdisciplinary approach that converges knowledge and skills from social …

Assay Replicability In Β-Glucosidase Enzyme Kinetics Across Laboratories, Nicole-Tia Najam, Jaime Mayoral

FIU Undergraduate Research Journal

Replicability is the foundation of research in any scientific discipline. Despite this fact, few studies address experimental variability within and across multiple institutions that operate under the same protocol. While consistency is usually well documented within the same lab, multi-institutional experiments may introduce new variables and, therefore, variability that may lead to inconsistent results. This study seeks to explore intra- and interinstitutional variability among enzyme catalytic efficiency values (K_M and K_cat/K_M) for the wild type of β-Glucosidase derived from Paenibacillus polymyxa. A standardized protocol for the assay was provided to all institutions that participated in …

Sustainability In Action: Green Infrastructure As A Marker Of Sustainable Urban Development, Brianna Nadine Santiago

FIU Undergraduate Research Journal

The current form and pace of urbanization is an ongoing threat to sustainable urban development. As these problems span social, environmental, and economic realms, it is imperative that any proposed solution is able to address these problems holistically. Although a number of silver-bullet solutions such as electric vehicle adoption have been introduced, they do not respond to the problems with an integrated approach. Tackling this problem will require a solution that can be changed and applied on a case-by-case basis. Therefore, the development of green infrastructure is the most efficient solution when responding to the problems threatening urban sustainability. The …

The State Of Knowledge Of Cca Diversity In The Caribbean Coral Reefs, Danielle Macias, Alain Duran, Fabio Nauer

FIU Undergraduate Research Journal

Crustose coralline algae (CCA) are a diverse and ecologically important species found in most of the world’s oceans. The current lack of taxonomic knowledge and relative abundance compromises our ability to predict species diversity numbers and, thus, their ecological roles and impacts on coral reefs. To gather a better understanding of the state of knowledge of crustose coralline algae taxonomy in the Caribbean, 107 different research papers, and other primary and secondary literature were studied; any source with taxonomical information, species identification, or genetic markers for identification was recorded. All Genebank codes were collected and sorted by supposed species marker …

Benefits Of Time Spent Outdoors In Early Childhood Education: A Systematic Review, Crismely Fermin, Monica Perez, Averill F. Obee, Katie C. Hart

FIU Undergraduate Research Journal

Several studies have provided evidence that time spent in nature (i.e., in natural environments or the outdoors) plays a beneficial role in child development by positively influencing children’s cognitive processes and states (Bowler et al., 2010; Bratman et al., 2012; 2014; Cameron-Faulkner et al., 2018; Kaplan, 1995; Mitchell et al.). However, to date, no study has looked systematically at the overall literature addressing the benefits nature plays in early childhood education, primarily through outdoor learning or time spent outside in natural environments. The purpose of the current study is to provide a systematic review of the empirical literature evaluating outcomes …

Understanding The Health Impacts Of Vehicular Emissions In South Florida: A Comprehensive Analysis, Janelle Ducheine, Noah Horesh, Jason C. Quinn

FIU Undergraduate Research Journal

South Florida is famous for its diverse cultural scene and year-round sunshine. This success, however, has not been without its consequences. While the region enjoys economic prosperity, the hidden cost of deteriorating air quality and adverse health effects from vehicle emissions necessitates urgent attention. Electric vehicles (EVs) have emerged as a potential solution, promising reduced emissions, and increased energy efficiency. However, the intricate life cycle emissions associated with EV energy production raise questions about their net benefits. Using predictive modeling and historical data, the study forecasts emissions trajectories and assesses their health implications. Results indicate a substantial reduction in pollutants …

Using Geochemical Tracers To Determine Seasonal Inputs Of Freshwater To A Coastal Estuary: Biscayne Bay, Fl, Melaney Lara, Rene M. Price

FIU Undergraduate Research Journal

Biscayne Bay is a coastal estuary that historically relied on rainfall and groundwater inputs from the karst Biscayne aquifer. The construction of major canals along the coastline has released point-source freshwater inputs into the bay, detrimentally affecting the Bay’s ecosystem balance. This project investigates the proportional inputs of freshwater between the wet and dry seasons in Deering Estate, adjacent to Biscayne Bay. The objective of this project was accomplished by analyzing the water chemistry of the bay using naturally occurring geochemical tracers. Water sampling occurred from May to August (wet season 2022) and January to March (dry season 2023); at …

Implications Of Microplastic Pollution For The Conservation Of Marine Protected Areas, Estefany D. Carvajal, Amanda Di Perna, Alain Duran

FIU Undergraduate Research Journal

Marine Protected Areas (MPAs) function as a tool for the protection and conservation of marine ecosystems. These designated areas should be free of any environmentally harmful pollutants. Microplastics (MPs) are plastic fragments measuring less than 5 mm (about 0.2 in). These fragments are an emerging threat to our oceans, and we are investigating the effectiveness of MPAs against these pollutants. We analyzed data gathered from research conducted on microplastic concentrations in MPAs and non-MPAs around the world. 53 MPAs and 53 non-MPAs around the world were used and the microplastic concentrations were deemed low, medium, or high by using the …

Marxism And The Left-Right Division In South Korea, Hyun Ok Park

Class, Race and Corporate Power

This paper delves into the dynamics of Korean Marxism and its political implications across three pivotal historical periods: the university student movement from the 1980s to the early 1990s, the era from the 1990s to the 2000s, and finally, the contemporary landscape characterized by the emergence of mass protests, the ascent of the far-right, and the spread of populism. It aims to provide insights into revitalizing Marxism in South Korea.

This paper is based on the authors talk presented in the panel, “Peril and Possibilities: Academic Marxism, Class Struggle, and the Growth of the Right Worldwide,” at the Socialist …

The Right-Wing Attacks On The Academic Left In India, Raju J. Das

Class, Race and Corporate Power

While right-wing attacks on the ideas of democracy and socialism in academia are a worldwide trend, in the remainder of the paper, I will focus on India, considered to be the largest democracy in the world. India has become a hotbed of right-wing politics, led by an authoritarian Hindu-nationalist government of the Bharatiya Janata Party (BJP). There are various reasons why this has happened which this paper will not discuss (Das, 2020a; Jaffrelot, 2021; Vanaik, 2017). Suffice to say that the BJP is the political wing of the fascistic paramilitary organization called RSS (or, National Volunteer Corps) which, in part …

Academic Marxism In The Crosshairs: What Is At Stake In The U.S.?, Robert E. Latham

Class, Race and Corporate Power

This essay considers the nature of attacks on academic Marxism in North America, still the center of capitalist power worldwide. Its main aim is to reflect on what is at stake in the surge of anti-Marxism associated with the right, specifically relating to the academy. While the far left poses little threat to the core of liberal capitalist power in the state and economy (and if anything is helping “do work” for the centre against the far right), the far right has made Marxism, especially academic Marxism, a core target and framing for its battle against liberal power and the …

Preface, Raju J. Das, Robert E. Latham

Class, Race and Corporate Power

The three articles were originally presented as papers on a panel organized by Robert Latham, at the Socialist Studies Conference at York University in 2023. While more or less focused on Marxism in academia, the articles deal with different regional contexts: Hyun Ok Park deals with South Korea, Robert Latham with the US, and Raju Das with India.

Building Global Labor Solidarity: Where We Are Today (Early 2024), Kim Scipes

Class, Race and Corporate Power

Labor activists have long-been encouraging workers to build international labor solidarity to empower each other and to improve all workers’ lives and well-being going back to before the First International. This tradition, while dismembered by the Cold War between the US and the UK on one hand and the Soviet Union on the other, has been resuscitated since the 1970s, with efforts by activists, scholars, and some workers to build cross-national border solidarity across the globe for workers, an effort that is growing.

This paper details these efforts, dividing the work between 1978-2011 and 2011 to today, listing some of …

Of Race, Racism And Racially Motivated Offences: A Review Of The Hate Crime And Public Order (Scotland) Act 2021, Olufemi O. Ilesanmi, Danielle Mckandie

Class, Race and Corporate Power

A relationship of social and legal significance seems to exist between the prohibition of expressions or manifestations of racism and the society’s preservation of racial diversity. To discourage racial prejudice and thereby protect each race, the state must manage its diversity well by legislating against racist hate offences. In Scotland, for example, the government boldly accepted that hate crimes, including racially motivated offences, are a serious problem requiring closer attention. Through its Hate Crime and Public Order (Scotland) Act 2021, the state resolves to tackle related criminality.

Focusing on the Act, this review examines whether or how race within the …

Capitalism, Global Militarism, And Canada’S Investment In The Caribbean, Tamanisha J. John

Class, Race and Corporate Power

At the end of the 1990s, there existed a belief that a growing Canadian military involvement in the Caribbean region was unlikely if it was not associated with Canada’s interest in Latin America (Klepak 1996). This view had such a large impact that today there is a dearth of information on Canada’s military involvement in the Caribbean region. Lacking systematic investigation, two myths have perpetuated: first that Canada has no stake or interest in Caribbean security, insofar as those interests cannot be tied to Canada’s interests in Latin America; and second, that all expressions of Canada’s involvement in Caribbean security …

Indigenous Form, Innovative Harmony, And Ingenious Rhythm In Manuel De Falla’S “Aragonesa”, Richard E. Mueller Ph.D.

Music & Musical Performance

The literature on the music of Manuel de Falla has called ample attention to the striking stylistic developments in Falla’s music of the 1920s. The familiar sound of Spain was replaced by the acerbic neo-classic idiom identified with the music of Stravinsky. The issue is complex. Falla’s new music continued to draw on Spanish resources and technical aspects of harmony and rhythm reflect continuities that can be traced back to the earliest works of Falla’s maturity, namely, the Cuatro piezas españolas (1909). The first of these pieces “Aragonesa” was composed largely in 1906, and before Falla re-located in Paris and …
