The relation of childhood depressive symptoms to behavior during a speech task
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
This study examined the relation of child depressive symptoms to their observed behaviors during a speech performance task. Previous work (Mavers & Bell, 2005) has demonstrated that children's anxiety was related to several observed difficulties...
Molecular free volume and viscosity changes in non-Newtonian fluids probed with molecular rotors
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
rotors, a sensitivity towards fluid flow (Haidekker MA et al, Sensor Lett. 2005; 3: 42-8), was exploited to observe shear-thinning behavior by probing flow velocity in a tube. Under application of sufficiently high shear rates to cause shear thinning...
Reduction of rhenium (V) oxo Schiff Base Complexes with triphenyl phosphine ligands
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
One approach to the treatment of cancer is to direct beta-emitting radionuclide to the cancer site where the radiation destroys the cancer cells. This can be achieved by coordinating the radioisotope in a very stable environment and linking it to a...
Death by the pounds: The effects of television on the obesity of African-American children and adolescents
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
. A self-concept theory was implemented to determine whether or not the content of television programs helped develop a child or teenagers concept of obesity. While it has not been possible to provide definite answers to our research questions, we...
Characterizing polymerization dynamics using fluorescent molecular rotors and magnetoelastic sensors
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The dynamics of polymerization are critical in many medical applications; for instance, polymers used to fill aneurysms must be timed accurately. Two distinct methods were examined for their ability to probe the polymerization ...
Aβ toxicity to SHSY-5Y human neuroblastoma cells
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Alzheimer's disease (AD) is a progressive neurodegenerative disorder that results in the loss of memory, language deterioration, confusion, restlessness, and eventually destroyed cognition. It is characterized by an ...
The effect of caloric restriction on the mitotic rates of mice
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Caloric restriction has been shown to cause a number of biological changes in animals including the retardation of the aging process. Calorically- restricted animals show an average increase in life span of 30 - 50 %. In ...
Determining an efficient protocol for production of neural stem cells
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Mouse embryonic stem (ES) cells are pluripotent cells derived from the inner cell mass of the developing blastocyst. When cultured in non-adherent dishes, ES cells form free-floating embryoid bodies (EBs). Cells within the ...
If it won't explode, hit it with a hammer: Facilitating chemical reactions at a liquid surface
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Collisional energy transfer at a gas-liquid interface may play an important role in the initial decomposition of multiphase combustibles. The energy feedback of hot, energetic, gaseous atoms, in this case Ar, striking the ...
L-NAME treatment in pigs
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Nω-nitro-L-arginine-methyl-ester (L-NAME) inhibits the enzyme nitric oxide synthase (NOS) which generates the physiologic messenger gas, nitric oxide (NO). In addition to its role as a vasodilator NO inhibits inflammation ...
Effect of clearcutting on the habitat within the clearcut and the surrounding forest and its relationship to the presence of wood thrush (Hylocichla mustelina) in the Current River Conservation Area
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Wood thrush were one of the few species of forest birds that increased in density on sites that received even-aged management as part of the Missouri Ozark Forest Ecosystem Project (MOFEP). One hypothesis is that this may ...
Parameter estimation and data reduction for cellular biophysical analysis
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Accurate estimation of cellular permeability parameters are an important part of designing and developing optimized cryopreservation protocols. Electronic Particle Counters measure cell volume by detecting changes in ...
Epithelial-mesenchymal transition of brain tumor cells is differentially regulated in response to dexamethasone
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
In the epithelial-mesenchymal transition of tumors, the loss of cohesivity and the migratory capability of cells determine the invasiveness and therefore the malignancy of the cancer. Understanding these biophysical ...
Membrane permeability of Bovine Ooctyes to Propylene Glycol and the application to the improvement of Cryopreservation
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
In this study, the goal was to determine the permeability parameters of bovine oocytes for water (Lp) and Propylene Glycol (PPG) at temperatures of 30, 20, 10, and 5°C. By determining permeability parameters, we can model ...
Construction of a knockout targeting vector to generate an Interleukin-13 Receptor α1 deficient Balb/c mouse
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
A recent publication from our lab has provided evidence for the involvement of the α1 chain of the Interleukin-13 cytokine receptor (IL-13Rα1) in the development of the neonatal immune system. Specifically, we have shown ...
Analysis of PDGF-AB and -BB in serum of intact and ovariectomized (OVX) pigs
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Previous studies in our group demonstrated that terminal microvascular networks in dura mater of ovariectomized (OVX) pigs undergo significant remodeling characterized by a decrease in microvessel density, capillary ...
A century later another surprise: A non-visual behavioral function of the white gene
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Discovery of the white mutation in Drosophila melanogaster has broadly influenced our understanding of the mechanisms of inheritance. We recently discovered a role of the white gene in memory formation. Thus, the white ...
Evaluation of the efficacy of test products to ameliorate the toxic effects of aflatoxin present in broiler chick diets
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
An in vivo study was conducted to evaluate the efficacy of several adsorbent test products to ameliorate the toxic effects of aflatoxin B1 (AFB1) in chicks. Ninety day-old straight run chicks were purchased from a commercial ...
