Gene Order Data From A Model Amphibian (Ambystoma): New Perspectives On Vertebrate Genome Structure And Evolution, Jeramiah J. Smith, S. Randal Voss Aug 2006

Gene Order Data From A Model Amphibian (Ambystoma): New Perspectives On Vertebrate Genome Structure And Evolution, Jeramiah J. Smith, S. Randal Voss

Biology Faculty Publications

BACKGROUND: Because amphibians arise from a branch of the vertebrate evolutionary tree that is juxtaposed between fishes and amniotes, they provide important comparative perspective for reconstructing character changes that have occurred during vertebrate evolution. Here, we report the first comparative study of vertebrate genome structure that includes a representative amphibian. We used 491 transcribed sequences from a salamander (Ambystoma) genetic map and whole genome assemblies for human, mouse, rat, dog, chicken, zebrafish, and the freshwater pufferfish Tetraodon nigroviridis to compare gene orders and rearrangement rates.

RESULTS: Ambystoma has experienced a rate of genome rearrangement that is substantially lower than mammalian …

Development And Testing Of A Low-Cost Condensation Detection System, Michael D. Montross, George A. Duncan, Richard S. Gates Jul 2006

Development And Testing Of A Low-Cost Condensation Detection System, Michael D. Montross, George A. Duncan, Richard S. Gates

Biosystems and Agricultural Engineering Faculty Publications

A condensation sensing and control system was designed to detect condensation using a commercially available leaf wetness sensor (LWS). The leaf wetness sensor was a variable resistance grid-type that responded to moisture on the surface. A circuit was developed to compare the LWS voltage output to a user specified reference voltage, and operate a relay for possible switching of a humidity control device (for example a fan and/or heater). The condensation detection system operation was validated in an environmental chamber in the laboratory using a heat exchanger and water bath. Condensate was immediately detected when the plate was cooled below …


Dissociation Of Automatic And Strategic Lexical-Semantics: Functional Magnetic Resonance Imaging Evidence For Differing Roles Of Multiple Frontotemporal Regions, Brian T. Gold, David A. Balota, Sara J. Jones, David K. Powell, Charles D. Smith, Anders H. Andersen Jun 2006

Dissociation Of Automatic And Strategic Lexical-Semantics: Functional Magnetic Resonance Imaging Evidence For Differing Roles Of Multiple Frontotemporal Regions, Brian T. Gold, David A. Balota, Sara J. Jones, David K. Powell, Charles D. Smith, Anders H. Andersen

Neuroscience Faculty Publications

Behavioral research has demonstrated three major components of the lexical-semantic processing system: automatic activation of semantic representations, strategic retrieval of semantic representations, and inhibition of competitors. However, these component processes are inherently conflated in explicit lexical-semantic decision tasks typically used in functional magnetic resonance imaging (fMRI) research. Here, we combine the logic of behavioral priming studies and the neurophysiological phenomenon of fMRI priming to dissociate the neural bases of automatic and strategic lexical-semantic processes across a series of three studies. A single lexical decision task was used in all studies, with stimulus onset asynchrony or linguistic relationship between prime and …

Prenatal Cocaine Exposure Alters Alpha2 Receptor Expression In Adolescent Rats, Rosemarie M. Booze, David R. Wallace, Janelle M. Silvers, Barbara J. Strupp, Diane M. Snow, Charles F. Mactutus Apr 2006

Prenatal Cocaine Exposure Alters Alpha2 Receptor Expression In Adolescent Rats, Rosemarie M. Booze, David R. Wallace, Janelle M. Silvers, Barbara J. Strupp, Diane M. Snow, Charles F. Mactutus

Neuroscience Faculty Publications

BACKGROUND: Prenatal cocaine exposure produces attentional deficits which to persist through early childhood. Given the role of norepinephrine (NE) in attentional processes, we examined the forebrain NE systems from prenatal cocaine exposed rats. Cocaine was administered during pregnancy via the clinically relevant intravenous route of administration. Specifically, we measured alpha2-adrenergic receptor (alpha2-AR) density in adolescent (35-days-old) rats, using [3H]RX821002 (5 nM).

RESULTS: Sex-specific alterations of alpha2-AR were found in the hippocampus and amygdala of the cocaine-exposed animals, as well as an upregulation of alpha2-AR in parietal cortex.

CONCLUSION: These data suggest that prenatal cocaine exposure results in a persistent alteration …

Cyclooxygenase-2 Mediates Microglial Activation And Secondary Dopaminergic Cell Death In The Mouse Mptp Model Of Parkinson's Disease, Rattanavijit Vijitruth, Mei Liu, Dong-Young Choi, Xuan V. Nguyen, Randy L. Hunter, Guoying Bing

Neuroscience Faculty Publications

BACKGROUND: Accumulating evidence suggests that inflammation plays an important role in the progression of Parkinson's disease (PD). Among many inflammatory factors found in the PD brain, cyclooxygenase (COX), specifically the inducible isoform, COX-2, is believed to be a critical enzyme in the inflammatory response. Induction of COX-2 is also found in an experimental model of PD produced by administration of 1-methy-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP).

METHOD: COX-2-deficient mice or C57BL/6 mice were treated with MPTP to investigate the effects of COX-2 deficiency or by using various doses of valdecoxib, a specific COX-2 inhibitor, which induces inhibition of COX-2 on dopaminergic neuronal toxicity and …

Why Dairy Farmers Need And Want High Quality Alfalfa Hay: Quality Of Hay = Performance And Profitability, Donna M. Amaral-Phillips Feb 2006

Why Dairy Farmers Need And Want High Quality Alfalfa Hay: Quality Of Hay = Performance And Profitability, Donna M. Amaral-Phillips

Kentucky Alfalfa and Stored Forage Conference

Why do dairy farmers want high quality forages, including alfalfa hay, to feed to their milking herds? Feeding high-quality forages results in greater feed intake and as a result, dairy cows produce more milk, and they often times can produce this milk more economically. With advancing stage of plant maturity, fiber digestibility and protein content of the alfalfa plant decreases while the amount of fiber increases. Consequently, less energy is available to the cow when it consumes more mature alfalfa. Energy is the nutrient that most often limits performance in dairy or beef cattle - not protein. The take home …


Alfalfa Hay For Horses, Robert Coleman Feb 2006

Alfalfa Hay For Horses, Robert Coleman

Kentucky Alfalfa and Stored Forage Conference

When horse owners consider hay for their animals a number of criteria are generally considered. Of major importance is the hay must be free of mold and dust, it needs to contain nutrients needed by the horse and it must be palatable. If these criteria are met, the type of hay should not matter. However, that is not the case with many horse owners. When discussing hay, many owners first consider the type of hay. Can it be alfalfa or should it be a grass or how about a mix of grass and a legume. If a group of horse …


Interpreting Forage Quality Test Reports, Donna M. Amaral-Phillips Feb 2006

Interpreting Forage Quality Test Reports, Donna M. Amaral-Phillips

Kentucky Alfalfa and Stored Forage Conference

Forages are the foundation for building diets for beef and dairy cattle, horses, sheep and goats. The quality of these forages directly impacts forage intake, animal performance, and, ultimately, the profitability to their owners. As the quality of forages decline, consumption of that forage decreases and the amount of grain or byproducts which must be fed increases. The cost for a unit of performance increases and/or the animal can not perform (i.e. milk or gain) to the optimum level thus lowering profitability to the animal owner. These relationships are especially true with young and high performance ruminants, such as high …


Moisture Management In Hay Making And Storage, Tom Keene, Doug Overhults Feb 2006

Moisture Management In Hay Making And Storage, Tom Keene, Doug Overhults

Kentucky Alfalfa and Stored Forage Conference

Making hay in central Kentucky can be one of the most trying on farm endeavors a producer can undertake. Our plentiful moisture, rolling topography, and climate make Kentucky ideal for producing high quality forage for either grazing or hay making. However, that same moisture, either in the form of rain or high humidity, can sometimes make it devilishly hard to make hay here in Kentucky.


Storing Alfalfa As Round Bale Silage, David C. Ditsch Feb 2006

Storing Alfalfa As Round Bale Silage, David C. Ditsch

Kentucky Alfalfa and Stored Forage Conference

Hay is the most popular method for storing alfalfa because it stores well for long periods and is better suited to cash sale and transportation than silage. However, silage may be a suitable option when and/or where hay curing is difficult. Due to numerous improvements in baling and wrapping equipment, it is possible to make high quality round bale silage using long (unchopped) alfalfa crops.
