An analysis of wireless security in Columbia, MO [Harper - abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The current state of wireless security in most areas can be estimated based on trends and collected data, but the complete picture is often unknown. Without collecting the information on most wireless access points in a ...
Biochemical characterization of phosphoproteins involved in defense signaling in the plant Arabidopsis thaliana [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Plants use an innate immune response for protection against pathogens that can be activated by elicitor molecules, such as a peptide from the flagellar tail of bacteria or the oligosaccharide chitin. Receptors reside at ...
Childhood overweight, food intake, and physical activity among Whites, Blacks, and Hispanics [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Childhood overweight has tripled in the last three decades for children 6-11 years of age. Overweight children are at higher risk for health problems and psychosocial issues. Although studies show Black and Hispanic children ...
What role does phosphorylation of cardiac troponin I play in elevating cardiac contractility following adrenergic stimulation?
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Myocardial performance is enhanced when adrenergic receptors are stimulated by catecholamines. The enhanced performance is mediated by cAMP dependent protein kinase A (PKA), which phosphorylates several proteins within the ...
99mTc-DPR-SSS-BBN for diagnosis of human cancers [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Receptor-specific, radiolabeled peptides have become increasingly popular as targeting vectors for the development of new diagnostic radiopharmaceuticals. The over-expression of certain receptors such as the gastrin releasing ...
Resolution of phylogenetic patterns within the angiosperm order Asparagales [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The angiosperm order Asparagales, is an economically important monocot order that includes onions (Allium), asparagus (Asparagus), and agaves (Agave). The core Asparagales includes ten families that form a monophyletic ...
Establishing the status of the American black bear in southern Missouri [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The current status of the black bear population in Missouri is largely unknown, as we have little to no information concerning its size, reproductive status and origin. However, evidence suggests that the bear population ...
What's in a worm; Uncovering polymophisms in soybean cyst nematode parasitism genes that correlate with virulence
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Soybean cyst nematode (SCN) is a parasitic worm that penetrates and infects soybean roots resulting in billions of dollars in crop loss annually. The most cost effective and environmentally friendly SCN management strategy ...
Are age-related differences in associative memory mediated by sensory decline? [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Naveh-Benjamin (2000) suggested an associative deficit hypothesis, explaining that some of the decline in episodic memory in older adults is due to their difficulty in binding unrelated components together into a cohesive ...
Plasma surface modification of silica particles for the increased strength of dental composites [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Many of the problems that exist today with current dental restoration materials can be eliminated through the use of nanofiber fillers such as hydroxyapatite. Materials like this can ultimately provide greater strengths ...
Functional analysis of conserved amino acid residues in the C-terminus of ACC synthase
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Ethylene is an important plant hormone that regulates growth, development, and stress response. Synthesis of Ethylene from its immediate precursor, 1-aminocyclopropane-1-carboxylic acid (ACC), is catalyzed by ACC oxidase. ...
The effect of reduced chromatin gene expression on an epigenetically regulated maize gene
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
In virtually all eukaryotic organisms, not just plants, genes are regulated at the level of chromatin. In a genomics approach to understand how expression of a gene can be regulated by its chromatin configuration, a series ...
Estrogen receptors in TRAMP C2 cells
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
According to a 2005 study done by the American Cancer Society, prostate cancer is the second most common type of cancer among American men. It has been shown that estrogen receptors alpha and beta play significant roles ...
The impairment of the prefrontal cortex due to high levels of dopamine and norepinephrine in relation to ADHD
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Attention- Deficit/ Hyperactivity Disorder (ADHD) affects many people from various backgrounds; however, not much is known about the disorder aside from clinical symptoms. Researchers are just beginning to dissect ADHD and ...
Metro and nonmetro youth: Evaluating differential pathways to delinquency
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Although much research has been conducted on risk factors and behaviors of delinquent youth, little is known about the nonmetro population and how they may differ from their metro counterparts. The purpose of this study ...
Sex and age specific infestation rates of raccoons (Procyon lotor) by American dog ticks (Dermacentor variabilis)
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
American dog ticks (Dermacentor variabilis) can have profound direct and indirect effects on human and wildlife hosts. However, there is little information on their short- or long-term rates of parasitism in free-ranging ...
Resolution of phylogenetic patterns within monocots [abstract]
