Effects of maternal diet on offspring in terms of behavior and overall health [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Polyunsaturated fatty acids have been touted to affect mammalian health and fecundity. Since stressed rodents tend to produce a surfeit of female pups, we studied the effects of these diets on female offspring behavior. ...
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 ...
Public perceptions of the environment: The role of mass media [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
This project examines the relationship between television news coverage of environmental issues and variations in public concern for the natural environment in the United States. Aggregate-level, time series data (GSS; ...
Effect of experimental forest treatments on gray treefrog (Hyla versicolor) habitat use [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Amphibian use of modified habitats has recently received more attention due to anthropogenic land-use patterns and the continued decline of species. We examined habitat use and abundance of gray treefrogs (Hyla versicolor) ...
Target test tube assembly process and design for the development of molybdenum-99 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Molybdenum-99 (Mo-99) is used to create Tc-99m, a widely used nuclear medicine diagnostic imaging radioisotope. In an attempt to decrease the need for imported Mo-99, development of mechanical systems to efficiently prepare ...
Rapid automated characterization of transposon insertion mutants in Desulfovibrio vulgaris Hildenborough by srnPCR [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Tn5 transposon mutagenesis occurs by a mechanism in which a segment of DNA (transposon) encoded in a plasmid is inserted into genomic DNA (the target) by a conservative (cut-and-paste) mechanism (Fig. 2). When the insertion ...
Juvenile salamander dispersal and use of terrestrial microhabitat cues
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The effects of deforestation are profound on amphibian populations. In order to balance land use practices with amphibian conservation, biologists and land managers must understand the habitat requirements of amphibians ...
Efficacy of turmeric (Curcuma longa) to ameliorate the adverse effects of T-2 toxin in broiler chicks
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
A 3-wk feeding study was conducted to evaluate the efficacy of turmeric (Curcuma longa) powder (TMP), containing a known level of curcumin to ameliorate the adverse effects of T-2 toxin in broiler chicks. Five pen replicates ...
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 ...
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) ...
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 ...
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 ...
Distributed video encoding: Development and implementation of methods to distribute computationally difficult work
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The proliferation of mobile media devices has cultivated the desire to have video on the go. These devices are ultra-compact and have a fraction of the storage space of a modern computer. For these devices to hold onto a ...
Methane adsorption in nanoporous activated carbon [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Natural gas is an economically and environmentally superior fuel to both gasoline and diesel. One challenge of this fuel is to find a high-capacity, low pressure method of storing it. Fractal networks of nanopores in ...
An assessment on resveratrol and its cellular protective properties
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Resveratrol is a polyphenolic compound found abundantly in plants such as knotweed or grapes. Under normal circumstances, it is in plants as a phytoalexin - an antibiotic produced by plants for defense under insults. Based ...
Characterization of a recombinant inbred line population for quantitative trait locus mapping
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Eukaryotes can regulate gene expression by epigenetic mechanisms at the chromatin level. One epigenetically regulated gene in maize is Pl1-Blotched, an allele of purple plant1, which activates anthocyanin pigment production. ...
Axonal regeneration following spinal cord hemi-transection in larval lamprey
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
In higher vertebrates, including humans, axonal regeneration following spinal cord injury (SCI) is very limited and there is little behavioral recovery. In contrast, lower vertebrates, such as lamprey, fish, and certain ...
Determining the structural dynamics of MMP-3/TIMP complex from NMR relaxation
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
MMP-3, or Stromelysin 1, is an proteolytic enzyme of the extracellular matrix that is involved in the repair of wounds. It is implicated in inflammation and cartilage damage and inflammation in rheumatoid arthritis and ...
IPTV: Streaming television over the Internet
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
