Improving Healthcare Workers’ Biohazardous Spill Safe Handling Skills, Zeina Mhanna, Ahmad Tassi

BAU Journal - Health and Wellbeing

All healthcare workers (HCWs) are exposed to biohazardous material. Biohazardous material may come in the form of spills, posing a risk of infection to (HCWs) who are not trained on how to safely handle them. While international guidelines recommend training HCWs on how to safely handle biohazardous spills in order to improve their skills, there are no studies that tackled this recommendation. The aim of this study is to improve HCWs’ biohazardous spill safe handling skills through training, and to evaluate the association between the HCWs’ improvement level and demographical characteristics. The study was conducted in a Southern Lebanese hospital …

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 …

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 (KM and Kcat/KM) 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 2024 Florida International University

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 …

Designing Sustainable Systems Using Nature’S Toolbox, Matthew J. Hasenjager 2024 University of Tennessee, Knoxville

Designing Sustainable Systems Using Nature’S Toolbox, Matthew J. Hasenjager

Faculty Publications and Other Works -- Ecology and Evolutionary Biology

Supporting the Earth’s human population without destabilizing planetary processes is the central challenge of sustainability science. Key to achieving this goal is designing systems that are robust and resilient to dynamic and unpredictable conditions. Bioinspiration leverages naturally evolved solutions to address such challenges, yet a solution derived from one-to-one correspondence between a natural and artificial challenge can be limited in its broader application. Here we advocate for an approach to nature-inspired design that forgoes mimicking specific solutions in favor of identifying general design features that enable natural systems to function. These features are not specific to any naturally evolved solution …

Synthesis Of Disubstituted Β-Hydroxy Acids For The Enzymatic Synthesis Of Chiral Β-Lactones, Laura Charlotte Underwood, James Christenson 2024 Bethel University

Synthesis Of Disubstituted Β-Hydroxy Acids For The Enzymatic Synthesis Of Chiral Β-Lactones, Laura Charlotte Underwood, James Christenson

Science Symposium

Beta-lactone synthetases are a class of enzymes which produce chiral beta-lactones, four-membered cyclic esters, from racemic beta-hydroxy acid substrates. Chiral beta-lactones are used as chemical synthons and as bioactive compounds, such as the FDA-approved drug, Orlistat. However, substrate specificity of stand-alone beta-lactone synthetases are poorly understood, and their use in chemoenzymatic synthesis of chiral bioactive compounds remains unexplored. This research focused on the organic synthesis of beta-hydroxy acids to probe the substrate specificity of this class of enzymes and to generate potentially bioactive compounds against essential tuberculosis enzymes. The beta-hydroxy acid 2-[(5-chlorofuran-2-yl)(hydroxy) methyl]hexanoic acid was synthesized from lithiated hexanoate and …

Screen For Beneficial Genetic And Chemical Modifiers In Drosophila Models Of Als And Traumatic Brain Injury, Will Bonderer

Biological Sciences Theses and Dissertations

The underlying molecular processes of aberrant protein expression in neurodegeneration are intricate and multifaceted, with ribosome-associated quality control (RQC) emerging as a promising avenue of exploration. Ribosome-associated quality control is integral to cellular function. Its evolutionarily conserved pathway encompasses a network of mechanisms designed to ensure the fidelity of protein synthesis, folding, and degradation within the cells of all eukaryotes. The ribosome, central to protein synthesis, plays a pivotal role in this quality control network, and its malfunction can lead to the accumulation of misfolded or aberrant proteins. In the context of neurodegenerative disorders, this dysfunction can have dire consequences. …


The Effects Of Light Cycle Disruption On The Reactive Oxygen Species Production In Zebrafish, Talia Sanders 2024 Georgia Southern University

The Effects Of Light Cycle Disruption On The Reactive Oxygen Species Production In Zebrafish, Talia Sanders

Honors College Theses

It has been proven that maintaining homeostasis is linked to regulation of circadian rhythms and the light cycles associated with them. Through investigation of zebrafish mitochondria subject to stress via unpredictable light cycle exposure, we previously studied the level of GSK3β protein as it relates to the health of the brain. The data has shown that when a brain undergoes stress, it results in the increased activation of GSK3β which leads to disruptions in circadian rhythm, inflammation, and cell death. Moreso, this overexpression results in reduced ATP production and lowered Complex 1 activity in the mitochondria. However, GSK3β activation is …
