Effect of follicular fluid supplementation on in vitro maturation of porcine oocytes [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The reproductive process that occurs in the female is controlled by a series of critical events. One such event that must occur is the "maturation" of the oocyte prior to its ovulation, so that it is capable of being ...
Mathematical modeling of obsessive compulsive disorder
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
We all at some point become fixated with certain actions or ideas. However, for the two to three percent of the world population with obsessive compulsive disorder (OCD), these fixations become so intense that the individual ...
Modeling friction stir welding of Al 2024-T3 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Friction stir welding (FSW) is a modification of the traditional friction welding. It is a process patented by The Welding Institute in Cambridge, England in 1991. It is a mechanical process whereby solid-state welding ...
Transcription factors leading the pathway to survival
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Asian Soybean Rust, a foliar disease, is caused by the fungal pathogen Phakospora pachyrhizi, which threatens soybean (Glycine max) production in many countries. In the absence of fungicide treatment, yield losses from ASR ...
Investigating the relationship between repeated DNA and gene silencing in the model organism Neurospora crassa
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
In order to maintain genomic integrity, organisms must possess the capability to combat unwanted elements such as retroviruses and transposons. In the filamentous fungus Neurospora crassa, the expression from repeated ...
Temperature-dependent preferences for advertisement-call frequency in females of Hyla versicolor
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Male treefrogs produce loud and persistent acoustic signals called advertisement calls to attract mates. Ectothermic animals like frogs face an interesting challenge, in that temperature can significantly impact characteristics ...
Physiology of vocal images in singing: A preliminary project on “online” singing training [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
This online program will help students understand the art and science of singing. During voice training, students and teachers may not have the same understanding of certain voice production techniques. While the teacher ...
Peer-to-peer networking: A security analysis
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Peer-to-peer (p2p) networks have developed as an alternative to the typical client-server model of networking which has a single point of entry, a server connected to all of the users on the network, with the server handling ...
Rodents gone wild in the southeastern section of Missouri in the Peck Ranch Conservation Area
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Management plans such as clear-cutting could affect the abundance of the species of rodents. The management of the forest can be responsible for the increasing or decreasing of rodent populations. I studied the rodents in ...
Neutron activation analysis of mercury in petroleum distillates
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
In liquefied natural gas (LNG) plants and nitrogen rejections units (NRU) that utilize aluminum heat exchangers, mercury (Hg) contaminates can result in corrosion of equipment, poisoning of catalysts, mechanical failure, ...
High phosphorus rapidly increase squash root magnesium, sodium and calcium concentration
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Previous studies in our laboratory have shown a significant impact of phosphorus nutrition on mineral element dynamics in plant roots and shoots (Reinbott and Blevins 1991, 1994, 1999). We hypothesize that increased P ...
MCP-1 and its role in lyme arthritis [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Lyme disease is caused by infection with the bacteria Borrelia burgdorferi, causing arthritis and carditis in infected animal models. The presence of spirochetes in the joint and other soft tissues induce recruitment of ...
Efficacy of modified constraint-induced movement therapy (mCIMT) protocol with clients with chronic stroke [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Objective: To determine efficacy of a new modified constraint - induced movement therapy protocol in clients with chronic stroke. Method: Each participant will undergo a six week modified constraint-induced movement (mCIMT) ...
Host proteins used in HIV assembly and budding
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Human immunodeficiency virus (HIV), the virus responsible for the AIDS pandemic, uses host cell machinery to assist its replication during the viral life cycle. A recent study randomly screened 21,000 host cell genes using ...
Natural variation in phenotypes associated with phototropins among geographically isolated populations of Arabidopsis thaliana [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
In Arabidopsis thaliana several phenotypes are controlled by blue light including chloroplast relocation movements and bending of the seedling stem in phototropism. These responses are controlled by the phototropins, phot1 ...
Electrohydrodynamic conduction pump - An experimental investigation [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Electrohydrodynamic pumps (EHD) were built and tested to further understand the nature of the technology. Two pumps built used a conductive pumping action to achieve flow within a dielectric fluid. The first pump (pump 11) ...
Properties of soil samples from below prehistoric Lake Agassiz
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Prehistoric Lake Agassiz, located in present day North Dakota, was a large lake (larger than all of the existing great lakes combined) fed by glacial runoff during the last ice age. The lake created a soft clay soil deposit, ...
A hybrid MRI-based hippocampus segmentation algorithm
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
We propose a new hippocampus segmentation method from MRI by integrating region-growing methods such as K-means clustering with PDE-based level set methods. Starting from a single point provided by the user, our algorithm ...
ROS from menadione induces astrocytic damage: protective effects of apocynin
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Oxidative stress is a core cause of neurodegenerative diseases such as Alzheimer's disease. When cells are under oxidative stress, they will produce a high amount of reactive oxygen species (ROS). ROS are small and highly ...
Identification of chloroplast DNA insertions in nuclear chromosomes of maize B73 line using the FISH procedure
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
It is known that chloroplast DNA can incorporate itself into the nuclear genome of plants. However, the sites of chloroplast (ct) DNA integration into chromosomes of maize have not yet been analyzed. This project is the ...
