The Molecular Analysis Of Hemoparasite Burdens Of Free-Ranging Lions (Panthera Leo) In The Kruger National Park, South Africa, Jamie R. Sherman
The Molecular Analysis Of Hemoparasite Burdens Of Free-Ranging Lions (Panthera Leo) In The Kruger National Park, South Africa, Jamie R. Sherman

Hemoparasites, or parasites of the blood transmitted by arthropod vectors, are commonly found in domestic animals and wildlife all over the world. Although hemoparasites can cause serious illness in domestic species, they often persist at low levels in wildlife without compromising general health. Current reports on wildlife parasitemia, specifically in lions (Panthera leo) are obtained from zoological parks and managed game reserves. However, few studies have examined parasitic burdens of free ranging lion populations. This study aims to semi quantitatively evaluate the presence of four representative hemoparasites including Babesia sp., Theileria sp., Cytauxzoon sp., and …
Effect Of Inflorescence Size On Female Choice In Wild Radish, Raphanus Raphanistrum, Mylenne H. Salinas

Sexual selection is an important mechanism of speciation. Originally studied in animals, researchers now argue that plants also exhibit characteristics that have been altered by sexual selection. Flower size, nectar production, pollen load, flower scent, and petal color are plant traits that participate in attracting mates through an intermediate pollinator. Although female choice has been demonstrated to enhance offspring quality in animals, a thorough analysis remains to be conducted in plants. In this study, I experimentally altered female choice by manipulating flower number on the hermaphroditic plant, Raphanus raphanistrum. Plants with smaller floral displays had reduced female choice; thus, allowing …
Production And In Vitro Investigation Of Vitamin B12-Based Bioprobes, Amy Rabideau
Production And In Vitro Investigation Of Vitamin B12-Based Bioprobes, Amy Rabideau
Honors Capstone Projects - All
Vitamin B12 (B12)-based bioprobes were produced and investigated in vitro for studying the B12 uptake pathway in certain cancer cell lines and their target-specific capabilities as imaging and/or contrast agents in vivo. An intrinsic factor (IF)-bound B12 conjugate (B12-ReBQBA) was produced containing rhenium(I) for in vitro analysis of the cubilin-expressing placental choriocarcinoma cell line. B12-ReBQBA has millimolar toxicity in vitro and excitation and emission wavelengths in the visible region, 488 nm and 560 nm, respectively. The rhenium metal in this bioprobe can be readily exchanged for the metastable radioactive metal technetium-99m …
Role Of Estrogen Receptor Expression In Estrogen (E-2)-Induced Modulation Of Th1 And Th2 Cytokine Responses, Bertille Gaigbe-Togbe
Role Of Estrogen Receptor Expression In Estrogen (E-2)-Induced Modulation Of Th1 And Th2 Cytokine Responses, Bertille Gaigbe-Togbe

Previous studies have demonstrated that repeated administration of 17β-estradiol (E-2) at a dose of 1mg/kg to both (SWR x NZB)F1 (SNF1) mice and (DBA x BALB/c)F1(DBF1) mice resulted in significantly decreased survival and increased appearance of lupus nephritis pathology. However, the ways in which estrogen modulates immune responses has yet to be fully understood, specifically in regard to modulations in TH1 and TH2 cytokine profile. Various studies have reported the presence of two estrogen receptors (ER), a and b, which have been found to be constitutively expressed in many immune cells. …
A Molecular Basis For Craniofacial Laterality In Fishes, Karen Adams
A Molecular Basis For Craniofacial Laterality In Fishes, Karen Adams
Honors Capstone Projects - All
Laterality, the preference for development on one side of the body, is essential to the vertebrate body plan. While the vertebrate skeleton usually develops symmetrically, the processes underlying craniofacial laterality are not well understood. Using zebrafish and cichlids as model organisms, this study focuses on the molecular basis of symmetric craniofacial development. Fgf8, Retinoic Acid, and wnt11 were examined to analyze their involvement in regulating craniofacial laterality. Fgf8 is known to play a role in proper jaw development. Because fgf8 and Retinoic Acid interact to achieve laterality of the somites during somitogenesis, the role of Retinoic Acid in regulating …

There is little comprehensive information on the distribution of root systems among coexisting species, despite the expected importance of those distributions in determining the composition and diversity of plant communities. This gap in knowledge is particularly acute for grasslands, which possess large numbers of species with morphologically indistinguishable roots. In this study we adapted a molecular method, fluorescent fragment length polymorphism, to identify root fragments and determine species root distributions in two grasslands in Yellowstone National Park. Aboveground biomass was measured and soil cores (2 cm diam) were collected to 40 cm and 90 cm in an upland, dry grassland …
