BACKGROUND: Microarray analysis and 454 cDNA sequencing were used to investigate a centuries-old problem in regenerative biology: the basis of nerve-dependent limb regeneration in salamanders. Innervated (NR) and denervated (DL) forelimbs of Mexican axolotls were amputated and transcripts were sampled after 0, 5, and 14 days of regeneration.

RESULTS: Considerable similarity was observed between NR and DL transcriptional programs at 5 and 14 days post amputation (dpa). Genes with extracellular functions that are critical to wound healing were upregulated while muscle-specific genes were downregulated. Thus, many processes that are regulated during early limb regeneration do not depend upon nerve-derived factors. …

Extending Grazing And Reducing Stored Feed Needs, Don Ball, Edward N. Ballard, Mark Kennedy, Garry D. Lacefield, Dan Undersander

Forage Symposium at the Kentucky Cattlemen’s Convention

Why extend the grazing season? For most livestock producers, extending the grazing season for their animals, or otherwise filling gaps in pasture forage availability to reduce stored feed needs, should be a high priority objective.

Teff: What Is It? Where Does It Fit In Kentucky, Bret Winsett

Forage Symposium at the Kentucky Cattlemen’s Convention

Teff (Eragrostis tef (zucc)) is an annual, warm season grass native to Ethiopia. Throughout its history, teff has been used more as a gluten-free grain for flour than as forage. However, in recent years, forage agronomists and producers have become increasingly interested in its potential contribution as a hay crop. Teff is characterized by a fairly large crown, many tillers, fine stems, a very shallow root system, rapid growth and high tonnage capability. During the vegetative stage, teff plants look somewhat similar to tall fescue in size and color. Teff tends to germinate quickly with good moisture, regrow quickly after …

Weed Control Options For Pastures, Jon Doran

Forage Symposium at the Kentucky Cattlemen’s Convention

What is a weed? A pasture or hayfield “weed” is any plant that you deem as being out of place and/or a plant that is decreasing your desired forage production. Weeds may be classified in several ways including broadleaf weeds, woody plants, and undesirable grasses. Besides decreasing forage, weeds can also interfere with forage utilization, grazing distribution, etc. There are several methods available to control weeds and increase production of and access to desirable forages. The three main methods are cultural, mechanical, and chemical. The cultural method is quite simple-a thriving grass stand is an excellent form of weed control …

Selecting Clover Varieties Wisely, S. Ray Smith

Forage Symposium at the Kentucky Cattlemen’s Convention

Although there are not a lot of new red clover varieties, several companies and Universities have active red clover breeding programs. In some ways, red clover is the easiest species to make variety recommendations for. Simply put, “only plant certified seed of improved varieties, never plant common seed.” University of Kentucky research has shown that the difference between improved varieties and common seed can be 6000 to 10,000 lb/acre in higher yield and 1 to 1 ½ years longer stand life. Sometimes you may “luck up” and find that the bag of cheap common seed you purchased was actually an …

Age May Be Hazardous To Outcome Following Traumatic Brain Injury: The Mitochondrial Connection, Lesley Knight Gilmer

University of Kentucky Doctoral Dissertations

Older individuals sustaining traumatic brain injury (TBI) experience a much higher incidence of morbidity and mortality. This age-related exacerbated response to neurological insult has been demonstrated experimentally in aged animals, which can serve as a model to combat this devastating clinical problem. The reasons for this worse initial response are unknown but may be related to age-related changes in mitochondrial respiration.

Evidence is shown that mitochondrial dysfunction occurs early following traumatic brain injury (TBI), persists long after the initial insult, and is severitydependent. Synaptic and extrasynaptic mitochondrial fractions display distinct respiration capacities, stressing the importance to analyze these fractions separately. …

Socioeconomic Status, Child Health, And Future Outcomes: Lessons For Appalachia, Janet Currie

University of Kentucky Center for Poverty Research Discussion Paper Series

Appalachians are in poor health relative to other Americans. For example, the ageadjusted all cause mortality rate for Appalachian in 2006 was over 900 per 100,000 compared to a rate of 760 per 100,000 for those outside of Appalachia. This essay shows that health disparities start before birth—the incidence of low birth weight is 90 1,000 in rural Appalachia compared to 83 per 1,000 outside the U.S. These disparities continue through childhood and into adulthood. Moreover, although African Americans are generally in poorer health relative to white Americans, disparities between Appalachia and the rest of the U.S. are much greater …

How Driver Risk Perception Affects Operating Speeds, Nikiforos Stamatiadis, Ted H. Grossardt, Keiron Bailey

Kentucky Transportation Center Faculty and Researcher Publications

Excessive speed is one of the primary safety hazards facing highway users. However, in many cases operating speeds exceed design speeds, and drivers generally ignore posted speed limits. The main objective of this research was to identify roadway elements and roadside features that could influence driver operating speeds in rural two-lane roads without compromising safety.

Virtual Reality video simulations were employed and drivers recorded the influence of these elements on their judgments about the appropriate driving speed. The driver/participants viewed 22 models projected on a large screen in a darkened room, simulating the windshield of a vehicle.

An Exploratory Study Of High School Students. Conceptions Of Atomic And Cellular Structure And Relationships Between Atoms And Cells, Elizabeth Anne Edwards Roland

University of Kentucky Doctoral Dissertations

Constructivist learning theory is based upon the tenets that students come to learning experiences with prior knowledge and experiences that the learner will choose from to make sense of the present situation. This leads to a mixture of understandings among students. This study proposed to reveal students‟ understanding of atomic structure and cell structure as well as the relationships between atoms and cells.

High school students from one private school participated in a paper-and-pencil test to uncover conceptual understanding and content knowledge of atoms and cells. The 120 participants were from grades: 9 (13m, 15f), 10 (9m, 20f), 11 (21m, …

Pyrilamine In The Horse: Detection And Pharmacokinetics Of Pyrilamine And Its Major Urinary Metabolite O-Desmethylpyrilamine, L. Dirikolu, A. F. Lehner, J Daniel Harkins, W. E. Woods, W. Karpiesiuk, R. S. Gates, M. Fisher, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Pyrilamine is an antihistamine used in human and veterinary medicine. As antihistamines produce central nervous system effects in horses, pyrilamine has the potential to affect the performance of racehorses. In the present study, O-desmethylpyrilamine (O-DMP) was observed to be the predominant equine urinary metabolite of pyrilamine. After intravenous (i.v.) administration of pyrilamine (300 mg/horse), serum pyrilamine concentrations declined from about 280 ng/mL at 5 min postdose to about 2.5 ng/mL at 8 h postdose. After oral administration of pyrilamine (300 mg/horse), serum concentrations peaked at about 33 ng/mL at 30 min, falling to <2 ng/mL at 8 h postdose. Pyrilamine was not detected in serum samples at 24 h postdosing by either route. After i.v. injection of pyrilamine (300 mg/horse) O-DMP was recovered at a level of about 20 ̄g/mL at 2 h postdose thereafter declining to about 2 ng/mL at 168 h postdose. After oral administration, the O-DMP recovery peaked at about 12 ̄g/mL at 8 h postdose and declined to <2 ng/mL at 168 h postdose. These results show that pyrilamine is poorly bioavailable orally (18%), and can be detected by sensitive enzyme-linked immunosorbent assay tests in urine for up to 1 week after a single administration. Care should be taken as the data suggest that the withdrawal time for pyrilamine after repeated oral administrations is likely to be at least 1 week or longer.

Maternal Antibody Transfer And Meningeal Worm Infection Rates In Kentucky Elk, Willie Elwood Bowling

University of Kentucky Master's Theses

Elk (Cervus elaphus) were historically present throughout Kentucky, but were extirpated by the mid 19th century. Kentucky Department of Fish and Wildlife Resources initiated elk reintroduction efforts in 1997, resulting in a self-sustaining population. I designed this project to study the effects of a parasitic nematode, meningeal worm (Parelaphostrongylus tenuis), on Kentucky’s elk herd. I examined potential maternal transfer of P. tenuis antibodies to elk calves, and investigated the relationship between elk habitat use and meningeal worm infection. I captured neonatal elk in 2004-06, fitted them with VHF transmitters, and collected blood samples for an enzyme-linked …

Integration Of An Extended Octagonal Ring Transducer And Soil Coulterometer For Identifying Soil Compaction, Santosh K. Pitla, Larry G. Wells, Scott A. Shearer

Biosystems and Agricultural Engineering Faculty Publications

The soil coulterometer is an "on-the-go" electro-mechanical system which collects impedance force data at multiple depths using an oscillating coulter. During the initial testing (summer 2006), only vertical soil impedance force data was collected using a pressure sensor. To improve the performance of the coulterometer, an extended octagonal ring transducer was integrated into the system to collect both the horizontal and vertical impedance forces given by the soil. In the summer of 2007, data was collected using the revised sensor from a typical central Kentucky field setting in a 0.8-ha (2-acre) plot. Four passes were made with the coulterometer. Seventy …

Systematics Of Ichneutine Parasitic Wasps (Braconidae: Ichneutinae), John Ray Fischer

Theses and Dissertations--Entomology

Ichneutine wasps have received little attention, despite their hypothesized placement at the base of an economically and ecologically important clade, the Microgastroidia s.s. This study combines previous hypotheses based on morphology with molecular evidence from multiple genes (28S: D1-5, 18S, COI, and CAD) to examine phylogenetic relationships of Ichneutinae using maximum parsimony and Bayesian inference. The three main ichneutine groups (Ichneutini, Muesebeckiini, and Proteropini) are each found to be monophyletic, but evidence exists that Ichneutinae itself is paraphyletic with respect to the rest of Microgastroidea s.l. Lispixys is found to be derived from within Oligoneurus, and Masonbeckia is almost …
