Benefits of soy-based feeds for fetal estrogen levels and obesity in adulthood
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
We examined the effect of maternal exposure to naturally occurring estrogenic chemicals in diets on circulating levels of estradiol in mouse fetuses. An animal's specific response to estrogen can vary according to the time ...
Mitochondrial DNA insertion into nuclear chromosomes of maize
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Every mitochondrion contains its own DNA separate from the nucleus. Over evolutionary time, most of the mitochondrial genes have moved to the nucleus so that now mitochondria require nuclear DNA to function. This type of ...
The influence of increased contact rate among raccoons on a nematode of public, and wildlife health concern, Baylisascar [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Natural and anthropogenic fluctuations in resource availability can alter the behavioral ecology and population dynamics of wildlife. This may have unintended consequences to wildlife disease ecology, as theoretical models ...
A comparative study of the feral horses of Shackleford Banks and Assateague Island [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Feral horses (Equus caballus) can be found today in isolated barrier island populations along the eastern coast of the United States. Assateague Island stretches for 37 miles along the coasts of Maryland and Virginia and ...
Genetic variation associated with adaptive traits in the African forest (Loxodonta cyclotis) and savanna elephant (L. africana) [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
There are two species of African elephant, the forest (Loxodonta cyclotis) and savanna elephant (L. africana). The savanna elephant is believed to have diverged from the forest species approximately 2.6 million years ago. ...
Cerebellar white matter abnormalities in phenylketonuria (PKU) [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Phenylketonuria (PKU) is a recessive genetic disorder that is characterized by an individual's body being unable to utilize the amino acid phenylalanine because of a dysfunction with the enzyme phenylalanine hydroxylase. ...
Pathogen susceptibility to Pseudomonas syringae in Arabidopsis thaliana [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Peptides may act as regulatory molecules that coordinate cellular responses needed for growth, differentiation and development. A novel family of small peptides, encoded by the DEVIL (DVL) gene family, was identified in a ...
Water flow sensor for eldercare [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Changes in hygiene habits can be an early indicator of mental and/or physical decline in elders. Since personal hygiene activity accounts for much of the water use in a home, and since much of this activity happens in ...
The effect of aldosterone on fatty acid oxidation in HepG2 cells [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The HepG2 cell line is an immorilized cell line harvested from a human hepatocellular carcinoma. This study is designed to investigate the affect of aldosterone on the mitochondrial function, specifically fatty acid ...
Processing brainwaves for hand-free control of devices [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
We have built a system to observe and analyze brainwaves for use in controlling devices such as wheelchairs and electronic prosthetics bypassing a need for the user to have use of their hands and/or other limbs. The system ...
Genetic mapping of QTL conditioning resistance to soybean cyst nematode in PI464925B
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Soybean cyst nematode (SCN) (Heterodera glycines Ichinohe) is estimated to cause the greatest yield losses to soybean [Glycine max (L.) Merr.] of any pest worldwide. It has been determined that host plant resistance is the ...
Desiccation rates of Rana sylvatica, Rana clamitans, and Bufo americanus in a fragmented forest
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Habitat loss and fragmentation are the primary causes in the declines of amphibian populations. Farming, urban sprawl, and logging have created a mosaic of developed and undeveloped land that may create barriers between ...
Brain natriuretic peptide decreases pulmonary artery pressure in rats with pulmonary hypertension
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
INTRODUCTION: B-type or Brain natriuretic peptide (BNP) was first isolated from the porcine brain, but it is primarily secreted from the cardiac ventricles in humans. As a cardiac hormone it has a physiologic regulatory ...
A study of academic self- concept, academic motivation, and self- esteem: Their relationship to academic achievement in college students
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
This study examined the reliability of the Academic Motivation Scale in a group of 263 undergraduate students enrolled in undergraduate psychology classes at a large Midwestern public university. Ethnicity, sex, age, and ...
Diversity of progeny from a single colony of Salmonella typhimurium after 19 months in sealed agar stabs
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Recent studies at the Cancer Research Center revealed numerous mutations in Salmonella typhimurium that had been sealed in agar stab vials and stored for over forty years. The bacteria that were conserved in over 20,000 ...
The effects of arousing video on attention and memory for attack vs. non-attack political advertisements
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
During the election season, it may appear that television viewers are bombarded with political advertisements. Furthermore, it may also appear that the majority of these advertisements are routinely negative. It has been ...
Pharmacokinetic modeling of cortisol binding to dietary fiber in the gastrointestinal tract
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Cortisol is a glucocorticoid hormone produced in the adrenal cortex during stressful situations. The purpose of this project was to determine whether cortisol binds to dietary fiber and to design a pharmacokinetic model ...
Investigation of type I collagen deposition in the glomeruli of COL1A2 deficient mice
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Type I collagen is the most abundant structural protein in the body, playing a major role in the strength and integrity of connective tissues. Alterations in the synthesis and structure of type I collagen result in a number ...
