Cynthia del Carmen Penaflor Diaz and Dr. Keith A. Crandall, Integrative Biology Introduction: Freshwater crayfishes are taxonomically distributed among three families; two Northern Hemisphere families, Astacidae and Cambaridae and one Southern Hemisphere family, Parastacidae,which includes the Astacoides species. The phylogenetic relationships among the freshwater crayfish families and their relationships to lobster-like ancestors has generated considerable […]
The Phylogeny of the Ephemerellidae (Ephemeroptera) Based on Molecular and Morphological Data
Jonathan Osborne and Dr. Michael Whiting, Integrative Biology A prior analysis of the families of Ephemerelloidea, based on 49 morphological characters, supported Ephemerellidae diverging basal to all other Ephemerelloid families (McCafferty and Wang, 2000). The family Ephemerellidae contains twenty genera in two subfamilies (McCafferty and Wang, 2000) and comprises the largest family among the pannote […]
A Systematic Classification of Fungus Gnats (Diptera: Mycetophilidae) of the Grand Staircase Escalante National Monument (GSENM), Utah
Mark Robert Nelson and Dr. C. Riley Nelson, Integrative Biology Mycetophilidae (fungus gnat) is a species-rich family of flies, existing on every continent but Antarctica, which has received little documentation on a global basis and no documentation in Utah (Vockeroth, 1981). In the most recent and comprehensive catalog of flies in North America only about […]
ORCA: DNA Repair
Clinton Morgan and Derek Mitchell Receiving an ORCA allowed me the time and means to learn how to do research. I personally only receive a portion of the award, so I will report what I personally have done. The most that I accomplished can be seen less in the results of my research and more […]
Understanding the Pathway of Steroidogenic Acute Regulatory Protein Using Bioluminescence
Andrew Miner and Dr. Allan Judd, Physiology and Developmental Biology Steroidogenic Acute Regulatory Protein (StAR) is a protein involved in the genesis of cortisol, testosterone, estrogen and other steroids. In fact, it is the rate-limiting step in the process of steroidogenesis. StAR is responsible for transporting cholesterol from the outside of the mitochondrial matrix to […]
Discovering Ancient Human Activities in Rural Maya Settlements: Soil Chemical Analysis of Ruins in Yucatán, México
Carmen Lopez and Dr. Richard E. Terry, Plant and Animal Sciences For many decades, scientists have been amazed by the magnificence of the Ancient Maya culture. Mayapan is a Postclassic (900-1500 A.D.) Maya city in the Yucatán Península that covers an area of 4 square km. It was the capital of the Postclassic Maya kingdom […]
A Novel Approach to Assessing the Metastatic Potential of Cancer Cells
Nyall Robert London, Jr. and Dr. Kim O’Neill, Microbiology and Molecular Biology Cancer remains a major cause of death around the world today. A major problem with cancer is metastasis or the spread of cancerous cells from the tumor to a secondary location. This occurs when cancer cells break away from a primary tumor, invade […]
Conservation Implications of Chukars (Alectoris chukar) in the United States
Randy T. Larsen and Dr. Jerran T. Flinders, Integrative Biology The Chukar (Alectoris chukar) is a medium-sized gallinaceous bird native to the Middle East and Asia first released in North America in 1893 in Illinois (Cottam et al. 1940). The sheer scale of subsequent releases is astonishing. Between 1931 and 1970 over 800,000 birds were […]
The Effect of Celecoxib on 17-Estradiol (E2) Treated MCF-7 Cells Using the Enzyme Linked Immunoabsorbent Assay (ELISA)
Jason Kinyon Abstract There has been evidence that shows inhibiting Cyclo-oxygense 2 (COX-2) enzymes may decrease angiogenic factors such as Vascular Endothelial Growth Factor (VEGF), which may prove beneficial in halting angiogenesis and metastasis, stopping cancer progression. It has been shown that there is a significant positive correlation between COX-2 and VEGF mRNA expression in […]
The Final Report on the Effect of Iodoacetate on Plasmodium Falciparum
The first part of my experiment was to find the lowest concentration of iodoacetate that would kill the parasite. First, I made a stock solution of .1 molar. From the stock solution six different dilutions were made: 10mM, .1mM, .05mM, .01mM, .005mM, and .001mM. These different dilutions were placed in 96 well plates with the […]
