Effects of beta-blockers on exercise in the geriatric population [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
This study is a retrospective look on the effects that Beta-blockers have on exercise outcome in the very old (those over the age of 80). Subjects for this research project were chosen out of the pool participants in the exercise specificity study...
Intimate opposition: Perceived closeness as a moderator of the impact of third-party opposition on romantic relationships [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Research has examined how third parties (e.g. parent-child relationships and peer relationships) affect the quality of romantic relationships. For instance, a pair of studies investigated the "Romeo & Juliet effect," to see whether parental...
Evaluation of Saint Louis Motorist Assist Program [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
My research evaluated the safety and efficiency impacts of the St. Louis Motorist Assist, a program of the Missouri Department of Transportation. The program's purpose is to improve freeway safety and expedite the flow of high-volume traffic...
Effect of stratification, gibberellic acid, and ethephon on Echinacea purpurea (L.) Moench and E. angustifolia D.C. seeds [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
with the low germination percentage of Echinacea has led researchers to determine what techniques will best help seeds break dormancy in order to improve the seedling germination percentage. The objective of this study was to find the treatment that most...
The development of conversation skills in toddlers [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Although the bulk of the research on children's language development focuses on vocabulary and grammar acquisition, competent language users know how to engage in conversation as well. Despite the fact that producing and comprehending conversations...
Do infants really understand object impermeability? [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Baillargeon et al. (1990) conducted an experiment in which infants viewed two events: a) a possible event (a bear appeared beside a clear cover, the display was hidden by a screen, and an adult hand reached behind the ...
Cloning auxin-responsive genes for future study in Arabidopsis [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Auxin, a plant hormone, serves as a signal for cells to grow, divide, and differentiate. Approximately 25 years ago, auxin was shown to rapidly affect the expression of specific genes. To date, only three families of auxin ...
Genetic mapping of a chromatin-level modifier [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
In many organisms, gene activity can be regulated by packaging of the DNA into chromatin. In general, loose chromatin structure is associated with transcriptionally active genes, while inactive genes have tighter chromatin ...
Identification of genes associated with root architecture under water stress in Zea mays L. [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Drought is the major limiting factor to crop production worldwide. Root architecture can influence drought response. Viviparous mutant (vp) embryos fail to become dormant and several of the vp mutants are also ABA (abscisic ...
Isolation of soybean (glycine max) root preferential promoter [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Soybean root preferential promoter is of great use to soybean genetic engineering. Such a promoter can be used to drive a tissue specific or preferential expression of integrated genes for either disease resistance or ...
Effects of fescue toxicosis on growth and thermoregulation of rats [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Tall fescue (Festuca arundinacia), a cool season forage grass, has been utilized by many farmers for over fifty year to feed livestock. Unfortunately, about half of fescue pastures are infected with an endophytic fungus ...
Development of explosion-resistant steel-stud wall systems [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Assuring the security of the nation's civil infrastructure is a priority. Technologies leading to effective protection of people and structures against bombings are of current interest to federal agencies. The National ...
Epitope tagging of a virulence protein in Haemophilus influenzae [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Haemophilus influenzae, a small, gram negative bacterium, is a commensal organism of the human upper respiratory tract. Before the introduction of the Hib vaccine, encapsulated H. influenzae of serotype b was a major cause ...
Structural characterization of enzyme-ligand complexes of GDP-Mannose hehydrogenase from P. aerguinosa [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The enzyme GDP-mannose dehydrogenase (GMD) from Pseudomonas aeruginosa catalyzes the committed step in the synthesis of the exopolysaccharide alginate. Alginate is a major component of P. aeruginosa biofilms that enable ...
Sex differences in muscle pain: Effects on behaviors and activities [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The current literature concerning sex differences in exercise-induced muscle pain is equivocal. This investigation builds upon our previous work on this issue by considering not only ratings of muscle pain, but also the ...
Intrapulmonary expression of PPAR in a rat model of pulmonary hypertension [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Activation of peroxisome proliferator-activated receptor-gamma (PPARγ) inhibits vascular smooth muscle proliferation and neointimal formation associated with pulmonary hypertension. Recently, our laboratory developed a ...
Understanding the language characteristics of children who stutter to improve assessment and treatment approaches [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Stuttering can significantly handicap a child, both socially and academically. Stuttering usually begins in the preschool years, at the same time as the child is developing language skills. We do not fully understand the ...
The effect of vegetation density on sampling volume by ultrasonic bat detectors (AnabatIIÆ) [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Ultrasonic detectors are becoming more common as a means of sampling bat activity and abundance. Many factors must be taken into consideration when using ultrasonic detectors, however. The sensitivity and range of bat ...
Characterization of cell proliferation and death factors in MMTV-neu tumors [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Apoptosis, or programmed cell death, is a biochemical process that is mediated by a multitude of cellular proteins to have the proper balance of cell growth and cell death. Altered apoptosis can give rise to cancer; tumors ...
