Studying The Effects Of Electronic Cigarette Exposure On Dna Mutation And Repair In Tetrahymena Thermophila, Tianna Sell, Katie Huisman, Matt F. Kvech

Carroll College Student Undergraduate Research Festival

The purpose of our experiment was to answer the question: Does exposure to aerosols expelled from an electronic cigarette affect the APN2 gene expression in Tetrahymena thermophila? It was hypothesized that the expression of APN2 would increase in Tetrahymena that were exposed to aerosol from a vape and that their growth rate would decrease. The mechanism and function of the APN2 gene is known as base excision repair. To test the hypothesis, Tetrahymena were randomly assigned to either a control group or a test group. A contraption was created to extract 12mL of aerosol from a Smok Baby Beast vape ...

Effect Of Bis (2-Ethylhexyl) Phthalate On Tetrahymena Thermophila Dcl-1 Gene Expression And Conjugation, Talya Vaira, Peyton Twete

Carroll College Student Undergraduate Research Festival

Phthalates, often referred to as plasticizers, are a group of chemicals used in hundreds of products including detergents, food packaging, and nail polish. Bis (2-ethylhexyl) phthalates (DEHP) have recently been shown to disrupt endocrine chemical balances, thereby causing reproductive strain. For this project, we wanted to explore how DEHP influences conjugation in Tetrahymena thermophila and to determine how DEHP exposure affects expression of the DCL-1 gene. The DCL-1 gene encodes the protein DCL-1 which is essential for transmitting genetic information during the process of conjugation in T. thermophila. We hypothesized that DEHP will act as a repressor of conjugation resulting ...

Hexavalent Chromium: Elucidating Its Carcinogenic Mechanism, And Testing Potential Preventative Treatments, Ryan Himes, Timothy Mayotte

Scholar Week 2016 - present

Cr(VI) (hexavalent chromium) has recently been found in the drinking water of over 250 million Americans. It is a powerful oxidizing agent, and is known to cause cancer, although the specific mechanism has yet to be elucidated. There is no known preventative treatment for Cr(VI) exposure, and the US EPA is currently determining what concentration of Cr(VI) in drinking water can be safely tolerated. This study sought to test the hypothesis that Cr(VI) cytotoxicity can be prevented by various antioxidants. We tested this hypothesis by exposing human embryonic kidney and human intestinal epithelial cells to Cr ...

Uncertainties Treatment For Wastewater-Based Epidemiological Estimation Of The Consumption Of Illicit And Prescribed Neuropsychiatric Drugs In Two Urban Communities In Kentucky Using Ammonium Normalized Population And Monte Carlo Simulation, Rhinannon Huffines, Tara Croft, Manoj Pathak, Bikram Subedi

Scholars Week

The conventional estimation of the prevalence of substance use in a community based on self-reported surveys typically underestimates the actual consumption. Drug’s residues in raw wastewater collected from the centralized wastewater treatment plants were utilized – Wastewater-Based Epidemiology (WBE) – to determine the consumption rate of illicit and prescribed neuropsychiatric residues in two urban communities in eastern Kentucky and two rural communities in western Kentucky. The ammonical nitrogen content in raw wastewater samples was used to minimize the uncertainty associated with the population dynamicity. Uncertainties associated with the several WBE parameters to back-calculate the consumption rate of drugs such as flow ...

Relative Importance Of Ions And Particles In Silver Nanoparticle Uptake And Accumulation In Keystone Estuarine Organisms; Prorocentrum Minimum And Crassostrea Virginica, Shelby Victoria Butz

Theses and Dissertations

In marine systems, silver is regarded as being one of the most toxic and readily accumulated metals, and is known to be taken up and accumulate within marine invertebrates, fish, phytoplankton and seaweeds. Reported open ocean concentrations of silver range from 0.1 – 2 ng L-1 while silver concentrations in coastal waters are typically 5 to 10 times higher than open ocean values (0.1 - 50 ng L-1). The determination of silver in marine and coastal waters presents several challenges including low concentrations and matrix complexity of seawater, which creates interferences and other challenges for many instrumental techniques creating a ...

Nutrient Limitation Of Phytoplankton In Lake Wateree, South Carolina: Implications For Future Water Quality Management, Kara M. Clyburn

Theses and Dissertations

Cultural eutrophication is a primary contributor to phytoplankton production in freshwater lakes from excess anthropogenic nutrient inputs, and resulting impacts on water quality, aquatic ecosystems, human and animal health are increasing worldwide. Understanding the factors that limit phytoplankton growth is an important strategy for identifying and managing nutrient sources and successfully controlling the over- enrichment of nitrogen (N) and/or phosphorus (P) in freshwater lakes. The Redfield molecular ratio of carbon (C), N and P maintains that the C:N:P molar ratio is 106:16:1 when nutrients are not limiting, and the ecosystem is balanced. A N:P ...

A Site Characterization And Assessment Of The Bushy Park Reservoir, A Charleston-Area Drinking Water Source, And Its Surrounding Watersheds In Response To Community Concerns, Bradley Joseph Chandler

Theses and Dissertations

Access to clean, safe drinking water is considered a basic human right (WHO 2004). It is vital to maintain adequate monitoring of source waters as well as to investigate claims of degraded source waters. In June of 2017, inaccurate reporting led many community members in Mt. Pleasant, SC to believe that their drinking water might be tainted, leading to elevated cases of brain cancer in children. Though steps were taken to test and ensure the drinking water was safe, fear over the health of the city’s drinking water still persists. This is largely due to the involvement of famed ...

Impact Of Pharmacogenomics On Clinical Outcomes In Major Depressive Disorder In The Guided Trial: A Large, Patient- And Rater-Blinded, Randomized, Controlled Study, John F. Greden, Anthony J. Rothschild

Open Access Articles

Current prescribing practices for major depressive disorder (MDD) produce limited treatment success. Although pharmacogenomics may improve outcomes by identifying genetically inappropriate medications, studies to date were limited in scope. Outpatients (N=1167) diagnosed with MDD and with a patient- or clinician-reported inadequate response to at least one antidepressant were enrolled in the Genomics Used to Improve DEpression Decisions (GUIDED) trial - a rater- and patient-blind randomized controlled trial. Patients were randomized to treatment as usual (TAU) or a pharmacogenomics-guided intervention arm in which clinicians had access to a pharmacogenomic test report to inform medication selections (guided-care). Medications were considered congruent ('use ...

Water And Women’S Participation The Case Of One Million Rural Cisterns Program In Serra Talhada, Pernambuco, Islene Pinheiro Façanha 2019 Universidade Nova de Lisboa, Faculdade de Ciências e Tecnologia and CENSE-Center for Environmental and Sustainability Research

Water And Women’S Participation The Case Of One Million Rural Cisterns Program In Serra Talhada, Pernambuco, Islene Pinheiro Façanha

wH2O: The Journal of Gender and Water

The participation of women is crucial in the domain of water management, given the vital role women play in the collection and maintenance of communal water supplies, and in regulating and controlling its use. Unfortunately, they are seldom considered in the development of water policies, and rarely are they members of bodies regulating water management. Current evidence suggests that the participation of women in rural water supply projects leads to improved outcomes for both women and the wider community. Using interviews, focus groups, questionnaires, and field observation, this paper explores the participation of women in the One Million Rural Cisterns ...

How Important Is Gender In Transboundary Groundwater Governance?: A Question For The Ramotswa Aquifer In Southern Africa, Stephanie Hawkins, Nicole Lefore, Saniso Sakuringwa, Matshidiso Thathana

wH2O: The Journal of Gender and Water

In semi-arid Sub-Saharan Africa, groundwater is a critical resource for rural livelihoods given the pressures on surface water and lack of piped delivery. Socially defined gen- der roles in water management often create disparities and inequalities regarding water access, use, and labour, making consideration of gender issues an important component of groundwater governance. Resources shared across borders raises the question about the relevance of and approach to gender in transboundary ground- water governance. This paper explores this question in light of the lack of gender responsive governance arrangements over transboundary groundwater resources. It uses qualitative methodologies to examine the need ...

Comparison Of Students ́Acceptance Of Conventional And Ecological Sanitation In Rural Schools, Claudia Wendland

wH2O: The Journal of Gender and Water

In rural areas of Eastern Europe, the Caucasus and Central Asia (EECCA) without reliable piped water supply, the conventional school sanitation system – the pit latrine – is leading to hygienic and environmental problems. Urine diverting dry toilets (UDDT) have been demonstrated to be an alternative, ecological sanitation solution for rural schools of the EECCA region. This study compares the acceptance, perception and absenteeism of students at schools served by the two different sanitation systems (ecosan versus pit latrine), comprising 18 schools in six countries of the region. A combination of quantitative and qualitative data collection methods was applied: absenteeism data from ...
