Hexavalent Chromium-Induced Cytotoxicity And Mutagenicity: A Study Of Protection By Ascorbic Acid And Epigallocatechin Gallate, Timothy P. Mayotte
Honors Program Projects
Hexavalent chromium, or Cr(VI), is a potent oxidizer and known carcinogen, that is found at varying levels in the water sources of more than 200 million Americans. However, the exact mechanism of carcinogenicity remains unknown, and though the government currently regulates total chromium levels, they have yet to determine a permissible exposure limit for Cr(VI). Moreover, there is currently no preventative treatment for Cr(VI). Because of Cr(VI)’s strong oxidative power, we hypothesized that it causes DNA mutation and cell death via oxidation and that antioxidants could prevent this from occurring. To test this, we first ...

The Wet Bridge Transfer System: An Novel In Vitro Tool For Assessing Exogenous Surfactant As A Pulmonary Drug Delivery Vehicle, Brandon J. Baer
Western Research Forum
Background:
Due to its complex branching structure, direct drug delivery to the remote areas of the lung is a major challenge. Consequently, most therapies, such as those treating pulmonary infection and inflammation, must utilize large systemic dosing, with the potential for adverse side effects. A novel alternative strategy is to use exogenous surfactant, a material capable of distributing throughout the lung, as a pulmonary drug delivery vehicle.
Objective:
Utilize an in vitro transferring system to assess exogenous surfactant (BLES) as a pulmonary delivery vehicle for different therapeutics.
Methods:
An in vitro technique was developed to simultaneously study surfactant delivery and ...

Health Disparities Among South Asians: Is Food Insecurity The Missing Link?, Valentina Chawdhury
Electronic Theses, Projects, and Dissertations
Objective: Food insecurity among South Asians in the US is a public health issue. Food insecure adults face a plethora of adverse outcomes and research shows that individuals with ancestral origins from South Asia have a higher susceptibility rate for cardiovascular disease after migrating to urban environments. As such, the goal of this study was to research possible barriers South Asians face when creating cultural dishes in the US.
Methods: This was a convergent parallel mixed-methods analysis to understand how South Asians feel about food insecurity. Pricing and availability of cultural food items were obtained from South Asian and Western ...

Development And Validation Of A Lc-Ms/Ms Method For Detection And Quantification Of 18 Antidepressants In Whole Blood, Linda Kim
Student Theses
Antidepressants are one of the most commonly prescribed drugs in America, with researchers reporting one in six Americans take some form of psychiatric drugs-mostly antidepressants (NBC News, 2016). Antidepressants are often present in combination with other drugs in suicides and drug-related deaths, so a sensitive and specific method to detect and quantify antidepressants is necessary. We developed a method for the detection and quantification of 18 different antidepressants in whole blood, with a range of 2.5-900 ng/mL and LOQ of 2.5 ng/mL. Three hundred uL of blood was used and the analytes were extracted using solid-phase ...

The popularity of TV shows such as Crime Scene Investigation (CSI) has generated high school students’ interest in forensics. Yet, forensic science is not commonly accessible to students, and especially students of color who often attend under-resourced high schools. This article presents the design, development, and evaluation of an online forensics course created for high school students of color who were a part of an informal science, technology, engineering, and mathematics (STEM) educational development program. Two essential elements guided the course design: the target learners (high school students of color) and integrating online instruction and hands-on laboratory activities involving real-world ...

Extraction, Purification And Evaluation Of Prmt5-Inhibitory Phytochemical Compounds For The Treatment Of Prostate Adenocarcinoma, Oliver H. Richmond Iii
Electronic Theses & Dissertations Collection for Atlanta University & Clark Atlanta University
The development and advancement of prostate cancer is supported by a plethora of genetic and proteomic abnormalities, including events of post-translational modifications. The protein arginine methyltransferase 5 (PRMT5) enzyme regulates epigenetic events of histone modifications and protein post-translational modifications within protein signaling pathways. PRMT5 functions by catalyzing the symmetric dimethylation of terminal arginine residues on target protein substrates. Under abnormal conditions of overexpression and upregulation, PRMT5 methyltransferase activity constitutively drives the growth and proliferation of dysregulated cells. Overexpression or upregulation of PRMT5 correlates with disease progression as observed among numerous cancer types, including breast, colorectal, leukemia, lung, melanoma and prostate ...

Reversal Of P-Glycoprotein And Breast Cancer Resistance Protein Mediated Multidrug Resistance In Vitro Using In Silico Identified Novel Compounds, Amila Nanayakkara
Biological Sciences Theses and Dissertations
Multidrug resistance (MDR) is a major cause of chemotherapy failure. Overexpression of ATP-binding cassette (ABC) transporters, P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) are two well-studied drug transporters which are associated with MDR. These two transporters also act as a major functional unit of the blood brain barrier to protect the brain from xenobiotics and toxins. Lack of clinically approved P-gp and BCRP inhibitors renders chemotherapy treatments of many MDR cancers ineffective and obstructs drug uptake into the brain.
Using computational methods, we have identified new compounds that inhibit P-gp (Brewer et al., Mol. Pharmacol. 2014). Several of these ...

Internal Design Of A Hydroponics Greenhouse For Tri Cycle Farms, Sarah Gould
Biological and Agricultural Engineering Undergraduate Honors Theses
Hydroponics is the agricultural technique of growing plants without soil, using other growing media and added nutrients in a solvent. It is an attractive agricultural method over conventional agriculture because it is more water efficient, is less labor intensive, yields higher quality crops in less time, and is easier to control. According to the Digital Journal, “hydroponics crop value is anticipated to grow to USD 27.29 Billion by 2022 at an estimated CAGR of 6.39% from 2015 to 2020” (Sawant, 2016). Alongside this growing market acceptance for hydroponics, there is also a local demand that requires only a ...

Nanostructure metals and metal oxides can be used for surface functionalization and combined with different materials to increase functionality. Recently, surface functionality has been of interest due to its multi-component and its ability to generate new material properties. One of its main application is the creation of nanomaterials because of its novel physical properties which contribute towards stabilization, strength, and catalytic properties. Nanomaterials makes it possible to fabricate objects in the nanoscale size range which offers beneficial physical properties. The nanomaterial distinctiveness allows for the creation of materials with unique characteristics for different applications such as photocatalytic coatings. Semiconductor and ...

Schistosomiasis is a neglected tropical disease rampant in developing countries. Widespread chemotherapy is reliant on a single drug, praziquantel, which increases the risk of resistance and creates an urgent need for the development of new alternatives for treatment. Fungal biotransformation is a well-documented tool in the pharmaceutical synthesis of new drugs. This study examined the efficacy of four fungal strains, Cunninghamella elegans (ATCC 9245 and ATCC 8688a), Umbelopsis ramanniana, (ATCC 9628) and Yarrowia lipolytica (ATCC 20225), in the biotransformation of praziquantel. Colonies were cultured, dosed with praziquantel, incubated for 5, 10 or 15 days to metabolize, after which the cultures ...

An Analysis Of Citizen Science And Its Effect On Marine Plastic Pollution, Kathryn Munster
Syracuse University Honors Program Capstone Projects
My Honors thesis is an analysis of pollution data to gain more insight about the growing problem of marine plastic pollution. I retrieved online datasets collected by the Clean Swell trash collection mobile application and then analyzed this data using the Python programming language. After my Python analysis, I used Tableau to create data visualizations. This paper analyzes the effect that citizen science has on plastic pollution. Syracuse University’s recycling and trash figures, provided by Syracuse Haulers, are also analyzed. The purpose of including Syracuse University’s data is to bring a local point of view to this project ...
