Membrane tether formation studied with magnetic tweezers
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Membrane tethers are ubiquitous nanometer-diameter cylindrical extensions of biological membranes. They form through either active or passive processes, by locally acting tensional forces. The physical properties of membrane ...
Developments of a pid temperature control system for a PCR chip
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
A Polymerase Chain Reaction on chip needs a precise temperature control for the reaction cycle. It is necessary to create and develop a good temperature control system for the operation of the PCR chip. Thin Pt film will ...
Phosphorylation of EGFR, ERK 1/2 and downstream transcription factors after P2Y2 receptor activation in a human submandibular gland cell line
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
P2 nucleotide receptors mediate a variety of biological responses and are activated by the extracellular nucleotides adenosine triphosphate (ATP), adenosine diphosphate (ADP), uridine triphosphate (UTP), uridine diphosphate ...
Exploring the possibility of new ERR isoforms in primates and humans
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
It is well known that estrogen is a risk factor for breast cancer. Hence, understanding the relationship between estrogen and breast cancer is significant for physiological and disease related pathways. Traditional thought ...
Adaptive controls and anesthesiology: Is there a future?
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
During a patient's surgery, an anesthesiologist has to periodically adjust controls on drug-delivery machines to keep a patient's consciousness at a desired level (a BIS value between 40 and 60). If this physician did not ...
Genotype and phenotype of Nicotiana alata x Nicotina rastroensis
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Gametophytic self-incompability (SI) is a process which enables plants to prevent inbreeding depression by rejecting self-pollen and pollen from closely related individuals. S-specific pollen rejection is controlled on a ...
Genotypic analysis of receptor-like protein kinases with leucine-rich repeat motifs
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Receptor-like protein kinases (RLKs) are transmembrane proteins that transmit extracellular signals across a membrane with the use of an intracellular kinase domain. RLKs play important roles in plant growth and development, ...
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 ...
Effects of diet and exercise on carotid lesions in male pigs
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The objective of this study was to examine the influence of aerobic exercise-training on atherosclerotic lesion appearance and composition in the carotid artery of male, miniature Yucatan pigs fed a high-fat, high-cholesterol ...
Synthesis and stability of rhenium tricarbonyl radiotracers
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Metal tricarbonyl complexes can be employed for cancer diagnosis and therapy using the radioisotopes Tc-99m or Re-188. These radiopharmaceuticals can be designed with specific physical and biological qualities such as low ...
Use of antisense oligonucleotides to enhance exon 7 incorporation in the pre-mRNA splicing of SMN2
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Spinal muscular atrophy (SMA) is a neurodegenerative disorder that is relatively common in humans and is caused by loss of the survival motor neuron 1 (SMN1) gene. SMA is the leading cause of hereditary infant mortality ...
Expression of a putative virulence protein of Haemophilus influenzae in E. coli
(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 system as well as an agent of diseases ranging from otitis media to meningitis. Nonencapsulated (nontypeable, ...
Functional analysis of MPK3 and MPK6, two mitogen-activated protine kinases in Arabidopsis thaliana
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Mitogen-activated protein kinase (MAPK) cascades are major pathways involved in the transduction of extracellular signals into intracellular responses. A MAPK cascade consists of three kinases; MAPK, MAPK kinase (MAPKK or ...
Determining the feasibility of anesthetization with a MS-222 solution in combination with cardiocentesis in male gray treefrogs (hyla versicolor)
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Ethyl 3-aminobenzoate (MS-222) is commonly used to anesthetize fish and amphibians, but few studies have investigated its effects on frogs. We experimented with the effects of combining the use of MS-222 with the extraction ...
Characterization of degeneration in the retina, brain and spinal cord of the Cln1 knockout mouse
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The neuronal-ceroid lipofuscinoses (NCLs; often referred to as Battens Disease) are a group of hereditary disorders of childhood. Symptoms of NCLs are characterized by neurodegeneration with progressive neural cell death ...
Modeling firing patterns of medium spiny neurons
