Target test tube assembly process and design for the development of molybdenum-99 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Molybdenum-99 (Mo-99) is used to create Tc-99m, a widely used nuclear medicine diagnostic imaging radioisotope. In an attempt to decrease the need for imported Mo-99, development of mechanical systems to efficiently prepare ...
Sigma receptor binding in normal mouse lung membranes [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The brain and many peripheral tissues (e.g., heart, spleen and liver) express sigma receptors that have been characterized by radioligand binding studies in vitro. In vivo studies indicate that sigma receptors are expressed ...
QTL mapping of suppressor of plant blotching1, modifiers of an epiallele [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Pl1-Blotched is an epigenetically regulated allele (an epiallele) of the purple plant1 gene, which activates synthesis of purple anthocyanin pigments. We identified a modifier called Suppressor of plant blotching 1 (Spb1), ...
Analysis of genetic drift within the highly repetitive KSP repeat domain and neurofilament medium [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Axonal diameter is one key component utilized to determine conduction velocity. However, the mechanism that influences axonal diameter must be stable within a given species, but flexible enough to adjust to the evolution ...
Do type I collagen defects that cause Osteogenesis Imperfecta result in an inherent muscle pathology? [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Osteogenesis imperfecta (OI) is a congenital connective tissue disorder characterized by decreased bone mineral density and increased bone fragility and susceptibility to fracture. In addition to skeletal fragility, patients ...
Rapid automated characterization of transposon insertion mutants in Desulfovibrio vulgaris Hildenborough by srnPCR [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Tn5 transposon mutagenesis occurs by a mechanism in which a segment of DNA (transposon) encoded in a plasmid is inserted into genomic DNA (the target) by a conservative (cut-and-paste) mechanism (Fig. 2). When the insertion ...
Photoacoustic detection of circulating melanoma cells in the plasma layer of the blood [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
When a melanoma patient is diagnosed, aggressive treatment is advised in an effort to contain the disease. Although the initial malignant cells are destroyed, it is impossible to determine whether or not the cancer has ...
Impact of prior/concurrent exposure to infectious diseases on variability in the 1918-19 flu epidemic on Newfoundland [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Between 1918 and 1920 nearly 2000 people on the island of Newfoundland died from influenza, pneumonia, and related illnesses. Deaths were recorded from all parts of the island, but there is substantial regional variability ...
Empowerment through journalism: social change through youth media production in northeast Brazil [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Journalism is a process in which people can begin to understand their realities and can be used as a powerful force in democratic societies for or against change. Specifically, youth journalism engages students in identifying ...
The manifestation of death in Nathaniel Hawthorne's gothic fiction [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Nathaniel Hawthorne is one of the most popular authors of American literature during the 19th century. My research then investigates how Nathaniel Hawthorne's “Alice Doane's Appeal” as well as “The House of Seven Gables” ...
Exploring the obstacles hindering the academic attainment of Latino/a students [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
There are many obstacles that work to hinder the academic attainment of Latino/a students; not only are these students a minority population on most university campuses, but the ratio of Latino/a students to actual state ...
Race relationships in Aphra Behn's Oroonoko [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
A number of scholars classify Aphra Behn's Oroonoko as one of the first anti-slavery or abolitionist narratives. However, my research discusses the seemingly problematic nature of Behn's text because of her decision to ...
Growth of orthographic representations in children with LLD [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
One aspect of word learning from reading is knowledge of the orthographic representation of a word. Children with language-learning disabilities (LLD) might be expected to have greater difficulties than peers acquiring ...
Effects of maternal diet on offspring in terms of behavior and overall health [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Polyunsaturated fatty acids have been touted to affect mammalian health and fecundity. Since stressed rodents tend to produce a surfeit of female pups, we studied the effects of these diets on female offspring behavior. ...
Prediction of superhelical proteins using machine learning methods [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The main objective is to use three state of the art machine learning methods to find the most efficient way for predicting and characterizing the superhelical proteins based solely on their sequence information. To achieve ...
Parent-adolescent relationships, sibling ordinal status, and adolescent adjustment [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Investigating the possible moderating affects of sibling ordinal status, researchers tested how differences in parent-child communication and trust between first-born and later-born children influence adolescent depressed ...
The Maelstrom: A play against genocide [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
