Group 11 Metal Compounds With Tripodal Bis(Imidazole) Thioether Ligands. Applications As Catalysts In The Oxidation Of Alkenes And As Antimicrobial Agents, Fangwei Liu, Reema Anis, Eunmi Hwang, Rafael Ovalle, Armando Varela-Ramírez, Renato J. Aguilera, María Contel

Publications and Research

New group 11 metal complexes have been prepared using the previously described tripodal bis(imidazole) thioether ligand (N-methyl-4,5-diphenyl-2- imidazolyl)2C(OMe)C(CH3)2S(tert-Bu) ({BITOMe,StBu}, 2). The pincer ligand offers a N2S donor atom set that can be used to coordinate the group 11 metals in different oxidation states [AuI , AuIII, AgI , CuI and CuII]. Thus the new compounds [Au{BITOMe,StBu}Cl][AuCl4]2 (3), [Au{BITOMe,StBu}Cl] (4), [Ag{BITOMe,StBu}X] (X = OSO2CF3 - 5, PF6 - 6) and [Cu{BITOMe,StBu}Cl2] (7) have been synthesized from reaction of 2 with the appropriate metal precursors, and characterized in solution. While attempting characterization in the solid state of 3, single crystals of the …

Pcr Amplification Of Trypanosoma Cruzi - Specific Dna From Raccoon Blood Samples, Colin Moss

Mahurin Honors College Capstone Experience/Thesis Projects

The parasitic protist Trypanosoma cruzi is the causative agent of Chagas Disease. Chagas Disease causes greater than 15,000 deaths each year, and nearly 28 million people are believed to be at risk of infection in Central and South America. This parasite has been described in many mammalian host species and has also been described in the United States. The purpose of this study was to attempt to use PCR to amplify T. cruzi-specific DNA directly from blood samples obtained from raccoons (Procyon lotor) trapped in Warren and Barren Counties of Kentucky in 2007 and 2008. DNA was …

The Proliferation Of Vascular Smooth Muscle Cells Depends On Thioredoxin 1 Protein In A Model Of Pulmonary Hypertension, Viktoria Nelin

Mahurin Honors College Capstone Experience/Thesis Projects

Pulmonary hypertension (PH) is a disease which manifests itself in the lungs of both adults and children. Vascular proliferation and remodeling are the hallmarks of PH and are found mainly in the pulmonary arterial smooth muscle cells (PASMC). The cause of PASMC proliferation and vascular remodeling in PH is poorly understood. Hypoxia, or low oxygen content, underlies many forms of PH. Hypoxia results in alterations in the redox balance of the PASMC. Therefore, the aim of this study was to examine the role of the thioredoxin system, an antioxidant system in the cell, in hypoxia-induced proliferation in PASMC. Protein was …

Assessing Social Benefits Of Domestic Rainwater Harvesting In Southern Kenya, Lindsey M. Filiatreau

Mahurin Honors College Capstone Experience/Thesis Projects

In the Kasigau location of the Voi District of Kenya, severe rainwater shortages closed fourteen water collection stations in 2008 and 2009, leaving ten water sources to service 15,000 people in the region. Few families in the area have domestic rainwater harvesting systems which are an easily implemented, low-cost means of water collection. I investigated the ability of rainwater catchment systems to modify family time budgets (by reducing water collection time) and lessen the severity of water scarcity (by supplying families a significant amount of water). Forty families participated in the research, 20 of whom received free installation of a …

Dna Sequence Variation In The Wingless Gene Product In Buckeye Butterflies (Genus Junonia), Bonnie Mccullagh

Mahurin Honors College Capstone Experience/Thesis Projects

Wingless is a highly conserved gene important to cell determination in development. In Drosophila, the wingless gene product has been identified as responsible for wing patterning. In Bicyclus anynana and Junonia coenia, wingless gene product is expressed in a fashion that suggests that it is involved in butterfly wing color pattern development. The wingless gene product has been implicated as a potential focal signal for patterning the eyespot of Junonia butterflies. I have shown that extensive DNA sequence variation (26.04% of the sequenced region) exists in 402 bp of wingless coding sequence among 338 specimens of Junonia from …

Screening Rnai Transformants Of Chlamydomonas For Reduced Expression Of The Photoreceptor Cryptochrome, Jeremy Webb

Mahurin Honors College Capstone Experience/Thesis Projects

Chlamydomonas reinhardtii is a unicellular green alga. In C. reinhardtii, three types of photoreceptors are known to be present: rhodopsins, phototropins, and cryptochromes. The single cryptochrome is the most likely photoreceptor for adjusting the circadian clock to the daily light/dark cycles, because cryptochromes are involved in clock entrainment in higher plants and insects. In this segment of the research, C. reinhardtii strains, which were genetically modified through transformation with a RNA interference construct, were screened for reduction in cryptochrome compared to the control strain. After C. reinhardtii cultures were harvested in complete darkness, all soluble proteins were extracted from the …

Assessment Of Prenatal Care And Perinatal Outcomes In Kasigau, Kenya, Allison Smith

Mahurin Honors College Capstone Experience/Thesis Projects

The World Health Organization (WHO) implemented the Millennium Declaration in 2000 to establish global health goals to be achieved by 2015. Two of these Millennium Development Goals (MDG’s) are directly related to maternal, neonatal and child health. Healthcare during the prenatal period can help achieve the WHO MDG’s for maternal health and child mortality. Evidence has shown that women in Kenya have limited access to prenatal care. This study focused on the prenatal care and postnatal outcome trends of the women in Kasigau, Kenya. Participants were surveyed in three villages (Rukanga, Makwasinyi, and Bhuguta) to determine if prenatal care was …

Human-Wildlife Conflict On Small, Subsistence Farms In Kenya, Christopher B. Colonna

Mahurin Honors College Capstone Experience/Thesis Projects

As human populations expand, wildlife suddenly competes with humans for resources and confrontation arises as a result. Rural Africa is typical of this problem. We surveyed local owners of small farms within the five villages surrounding Mount Kasigau in Southeast Kenya to quantify losses due to wildlife depredation on both subsistence and cash crops as well as to discover the patterns and variables influencing farmer-wildlife confrontations in the region. We found no statistically significant correlations among the value of damage per acre, the distance from the bush, or the distance to the nearest water source. We did find statistical significance …

Effective And Affordable Novel Arsenic Removal Technology, Benadin Varajic

Mahurin Honors College Capstone Experience/Thesis Projects

Arsenic contaminated drinking water is a serious worldwide issue faced by millions of people every day. Long term exposure to arsenic levels above the World Health Organization’s (WHO) standard of 10 ppb has been associated with severe detrimental health effects including cardiovascular disease and cancer. Although current water purification technologies exist, their implementation is an unrealistic goal by many third world nations for a variety of reasons, the most common being the cost associated with what are typically complicated procedures. This study strives to discover an effective and affordable novel arsenic removal technology.

The first step of this study was …

Combining Bioinformatics And Chemical Biological Approaches To The Study Of Signaling Pathways In Parasitic Nematodes, William R. De Martini

Theses, Dissertations and Culminating Projects

Lymphatic filariasis (elephantitis) is a disfiguring disease caused by thread-like nematodes. This disease affects the lives of over 120 million people and over one billion people are at risk for infection in endemic regions. Drugs used to treat this disease suffer from toxicity and emerging resistance and new therapies need to be identified. Our laboratory has been studying the filarial parasite, Brugia malayi (B. malayi), one of the causative agents of this disease. The laboratory is focused on the study of critical protein kinase signaling pathways, necessary for parasite protective anti-oxidative responses, as potential therapeutic targets. We have previously determined, …

Impacts Of The Species Elaeagnus Umbellate On The Soil And Water Quality Of The Pierce Cedar Creek Institute Ecosystem, Yacoub Aljobeh, Kristin Engerer

Symposium on Research and Creative Expression (SORCE)

The species Elaeagnus umbellate, more commonly known as autumn olive, is a shrub that is invasive to the United States and indigenous to East Asia. Even though the autumn olive is not native to North America, it was able to thrive and adapt to the new environment by using its ability to fix nitrogen. Nitrogen-fixing is a process where plants intake molecular nitrogen from the atmosphere and convert it into other forms of nitrogen that can be used by the plants. One of the nitrogen-fixing by-products is nitrate. Excessive amounts of nitrate can easily leach from the plant’s root …

Testing The Potential Of Using Fungi To Convert Human Waste Into Protein, Alex Zapata, Elizabeth Phillippi, Blair Mitchell, Jon Schoer, Michael Watters

Symposium on Research and Creative Expression (SORCE)

We report on the results of a pilot experiment designed to test the potential of filamentous fungi (mold) to reduce solid waste (feces) while converting it into a consumable, high protein food product. Feces represent an untapped resource. Filamentous fungi are natural decomposers with the ability to use this resource. Many filamentous fungi are safe to eat. We examined growth in order to determine the conditions which maximized the rate of conversion of solid waste into fungal biomass. For this pilot, we compared the effect of different lengths of incubation, different methods of aeration, and different available surface area. The …

Reduced Activity Of Multiple Endocrine Disrupting Compounds: 17Β-Estradiol And Bisphenol A With A Chemi-Luminescent Assay, Anna C. Ortiz^, Roberto J. De La Torre-Roche, Marc B. Cox, Wen-Yee Lee*

COURI Symposium Abstracts, Spring 2011

The concern about the impacts of endocrine disrupting compounds (EDCs) in the environment has increased recently with their high occurrence in surface waters and sex changes in various aquatic organisms. EDCs include ubiquitously used pharmaceuticals and personal care products, such as soap, detergents, contraceptives, and other medicines, which are released constantly into the environment, in waste water treatment plant effluent. Though toxicological effects of these individual, EDCs have been studied, knowledge on how these chemicals interact together in the environment is very limited. The objective of this project is to study the multi-residue effect of EDCs using a chemi-luminescent yeast …
