Effects Of Uvb-Induced Oxidative Stress On Protein Expression And Specific Protein Oxidation In Normal Human Epithelial Keratinocytes: A Proteomic Approach, Marzia Perluigi, Fabio Di Domenico, Carla Blarzino, Cesira Foppoli, Chiara Cini, Alessandra Giorgi, Caterina Grillo, Federico De Marco, D. Allan Butterfield, Maria E. Schininà, Raffaella Coccia

Chemistry Faculty Publications

BACKGROUND: The UVB component of solar ultraviolet irradiation is one of the major risk factors for the development of skin cancer in humans. UVB exposure elicits an increased generation of reactive oxygen species (ROS), which are responsible for oxidative damage to proteins, DNA, RNA and lipids. In order to examine the biological impact of UVB irradiation on skin cells, we used a parallel proteomics approach to analyze the protein expression profile and to identify oxidatively modified proteins in normal human epithelial keratinocytes.

RESULTS: The expression levels of fifteen proteins - involved in maintaining the cytoskeleton integrity, removal of damaged proteins …

Growing Alfalfa For Wildlife, Don Ball

Kentucky Alfalfa and Stored Forage Conference

Alfalfa has long been recognized as a superb forage crop, which is why it is widely grown for dairy cattle, horses, sheep, and many other types of domesticated forage-consuming animals. Reasons for its popularity include wide adaptation, excellent nutritive value, good yield potential, perennial growth habit, a long growing season, and the fact that (in association with Rhizobium bacteria) it is a nitrogen-fixing legume that does not require periodic applications of nitrogen fertilizer.

Alfalfa Varieties For The Future, Joe Bouton

Kentucky Alfalfa and Stored Forage Conference

When breeding tomorrow’s alfalfa varieties, most groups employ a model of combining traditional plant breeding with biotechnology tools in order to incorporate useful traits. In this model, the conventional variety development process will be the method of choice for most traits where breeders have traditionally made progress such as adaptation, heading date, disease and insect resistance, general persistence conditions such as grazing and traffic tolerance, and even yield. It has been very successful in adding economic value to the forage and livestock operations of many producers (Bouton 2007). These traditionally developed varieties will also be used as the germplasm platform …

Do's And Don'ts In Grazing Alfalfa, Ken Johnson

Kentucky Alfalfa and Stored Forage Conference

I want to discuss some of the issues in a talk I presented nearly twenty years ago. At that point we had been grazing Alfalfa about eight years and made some general remarks about the concerns I had at the time. I will look at these as presented then and how the thoughts may have changed.

Is There A Benefit To Alfalfa Balage?, Gary Bates

Kentucky Alfalfa and Stored Forage Conference

Making hay in the mid-South has always been a difficult process. High humidity and rainfall often make drying a long, tedious, if not impossible proposition. Over the last few years there has been an increased interest in making round bale silage, or balage, from forage crops. Fermenting alfalfa for storage has several advantages and disadvantages over regular haymaking systems.

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 the selection of 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 …

Value Of Alfalfa In Rotation, S. Ray Smith

Kentucky Alfalfa and Stored Forage Conference

There are about 23 million acres of alfalfa in the US. Alfalfa plus other hay is the most valuable crop in the US, behind only corn and soybeans. In Kentucky alfalfa is planted on over 300,000 acres and is an economically important crop for beef and dairy farmers, cash hay producers, and provides tremendous benefits for subsequent crops. There are also many non-agricultural benefits to alfalfa.

Advances In Alfalfa Seed Coatings, Bill Talley

Kentucky Alfalfa and Stored Forage Conference

The volume of alfalfa being sold as coated seed has been in the growth mode for several years. This growth is being fueled by greater acceptance from the producer, as well as the many value added components that are now labeled and being offered as seed treatments. Originally seed coatings were looked at as a better way to deliver rhizobia to insure plant nodulation. This is still one goal, but many more value added components are now labeled that offer better plant protection, increased water absorption, enhanced germination, and micro-nutrient availability, as well as insect and parasite control. Another area …

High-Excitation Emission Lines Near Eta Carinae, And Its Likely Companion Star, Andrea Mehner, Kris Davidson, Gary J. Ferland, Roberta M. Humphreys

Physics and Astronomy Faculty Publications

In order to study the distribution of gas and ionizing radiation around η Car and their implications for its likely companion star, we have examined high-excitation emission lines of [Ne III], [Fe III], etc., in spectra obtained with the Hubble Space Telescope/Space Telescope Imaging Spectrograph instrument during 1998-2004. Our principal results, some of them unexpected, are as follows. (1) The high-excitation fluxes varied systematically and non-trivially throughout η Car's 5.5 year spectroscopic cycle. Instead of rising to a plateau after the 1998 ''event,'' they changed continuously with a maximum in mid-cycle. (2) At one significant location a brief, strong …

Methods And Kit For Determination Of Prostacyclin In Plasma, Sylvia Daunert, Michael Poon, Urvee Desai, Sapna K. Deo

Chemistry Faculty Patents

A solid-phase immunoassay for 6-keto-Prostaglandin F_1α, the stable hydrolysis product of prostacyclin (Prostaglandin I₂) is disclosed. Prostacyclin, a potent vasodilator with anti-platelet and anti-proliferative properties is an effective treatment for primary pulmonary hypertension and pulmonary arterial hypertension associated with scleroderma and scleroderma-like syndrome. Levels of 6-keto-Prostaglandin F_1α can be directly correlated with levels of prostacyclin. Therefore, 6-keto-Prostaglandin F_1α has become the indicator of choice to measure prostacyclin levels. The single step immunoassay for 6-keto-Prostaglandin F_1α uses the bioluminescent protein, aequorin as a label. Analyte-label conjugates were constructed by linking the carboxyl group of …

Biochemical Characterization Of Human Mismatch Recognition Proteins Mutsα And Mutsβ, Lei Tian

University of Kentucky Doctoral Dissertations

The integrity of an organism's genome depends on the fidelity of DNA replication and the efficiency of DNA repair. The DNA mismatch repair (MMR) system, which is highly conserved from prokaryotes to eukaryotes, plays an important role in maintaining genome stability by correcting base-base mismatches and insertion/deletion (ID) mispairs generated during DNA replication and other DNA transactions. Mismatch recognition is a critical step in MMR. Two mismatch recognition proteins, MutSα (MSH2-MSH6 heterodimer) and MutSβ (MSH2-MSH3 heterodimer), have been identified in eukaryotic cells. MutSα and MutSβ have partially overlapping functions, with MutSα recognizing primarily base-base mismatches and 1-2 nt ID mispairs …

LP Bounded Point Evaluations For Polynomials And Uniform Rational Approximation, Erin Militzer

University of Kentucky Doctoral Dissertations

A connection is established between uniform rational approximation, and approximation in the mean by polynomials on compact nowhere dense subsets of the complex plane C. Peak points for R(X) and bounded point evaluations for H^p(X, dA), 1 ≤ p < ∞, play a fundamental role.

Palinspastic Reconstruction Around A Thrust Belt Recess: An Example From The Appalachian Thrust Belt In Northwestern Georgia, Brian Stephen Cook

University of Kentucky Doctoral Dissertations

In a well-defined subrecess in the Appalachian thrust belt in northwestern Georgia, two distinct regional strike directions intersect at approximately 50°. Fault intersections and interference folds enable tracing of both structural strikes. Around the subrecess, tectonically thickened weak stratigraphic layers—shales of the Cambrian Conasauga Formation—accommodated ductile deformation associated with the folding and faulting of the overlying Cambrian–Ordovician regional competent layer. The structures in the competent layer are analogous to those over ductile duplexes (mushwads) documented along strike to the southwest in Alabama.

The intersection and fold interference exemplify a long-standing problem in volume balancing of palinspastic reconstructions of sinuous thrust …

Measurement Of Single-Target Spin Asymmetries In The Electroproduction Of Negative Pions In The Semi-Inclusive Deep Inelastic Reaction N↑(E,Éπ¯)X On A Transversely Polarized 3he Target, Chiranjib Dutta

University of Kentucky Doctoral Dissertations

The experiment E06010 measured the target single spin asymmetry (SSA) in the semiinclusive deep inelastic (SIDIS) n↑(e,éπ¯)X reaction with a transversely polarized ³He target as an effective neutron target. This is the very first independent measurement of the neutron SSA, following the measurements at HERMES and COMPASS on the proton and the deuteron. The experiment acquired data in Hall A at Jefferson Laboratory with a continuous electron beam of energy 5.9 GeV, probing the valence quark region, with x = 0.13→0.41, at Q² = 1.31→3.1 GeV². The two contributing mechanisms to the measured asymmetry, viz, the …

A Markov Transition Model To Dementia With Death As A Competing Event, Liou Xu

University of Kentucky Doctoral Dissertations

The research on multi-state Markov transition model is motivated by the nature of the longitudinal data from the Nun Study (Snowdon, 1997), and similar information on the BRAiNS cohort (Salazar, 2004). Our goal is to develop a flexible methodology for handling the categorical longitudinal responses and competing risks time-to-event that characterizes the features of the data for research on dementia. To do so, we treat the survival from death as a continuous variable rather than defining death as a competing absorbing state to dementia. We assume that within each subject the survival component and the Markov process are linked by …

High Accuracy Multiscale Multigrid Computation For Partial Differential Equations, Yin Wang

University of Kentucky Doctoral Dissertations

Scientific computing and computer simulation play an increasingly important role in scientific investigation and engineering designs, supplementing traditional experiments, such as in automotive crash studies, global climate change, ocean modeling, medical imaging, and nuclear weapons. The numerical simulation is much cheaper than experimentation for these application areas and it can be used as the third way of science discovery beyond the experimental and theoretical analysis. However, the increasing demand of high resolution solutions of the Partial Differential Equations (PDEs) with less computational time has increased the importance for researchers and engineers to come up with efficient and scalable computational techniques …
