Manganese Superoxide Dismutase: Guardian Of The Powerhouse, Aaron K. Holley, Vasudevan Bakthavatchalu, Joyce M. Velez-Roman, Daret K. St. Clair

Toxicology and Cancer Biology Faculty Publications

The mitochondrion is vital for many metabolic pathways in the cell, contributing all or important constituent enzymes for diverse functions such as β-oxidation of fatty acids, the urea cycle, the citric acid cycle, and ATP synthesis. The mitochondrion is also a major site of reactive oxygen species (ROS) production in the cell. Aberrant production of mitochondrial ROS can have dramatic effects on cellular function, in part, due to oxidative modification of key metabolic proteins localized in the mitochondrion. The cell is equipped with myriad antioxidant enzyme systems to combat deleterious ROS production in mitochondria, with the mitochondrial antioxidant enzyme manganese …

Anatomical Correlates To Nectar Feeding Among The Strepsirrhines Of Madagascar: Implications For Interpreting The Fossil Record, Magdalena N. Muchlinski, Jonathan M. G. Perry

Neuroscience Faculty Publications

One possible ecological scenario for the origin of primates is the archaic pollination and coevolution hypothesis. Its proponents contend that the consumption of nectar by some early primates and the resulting cross-pollination is an example of coevolution that drove adaptive radiations in some primates. This hypothesis is perhaps ecologically sound, but it lacks the morphology-behavior links that would allow us to test it using the fossil record. Here we attempt to identify cranial adaptations to nectar feeding among the strepsirrhines of Madagascar in order to provide such links. Many Malagasy strepsirrhines are considered effective cross-pollinators of the flowers they feed …

Benefits Of "Improved" Grazing--More Important Now Than Ever!, Garry D. Lacefield

Kentucky Grazing Conference

At this Conference twelve years ago I talked about the “Benefits of Improved Grazing”. We have had aspects of that theme at every Kentucky Grazing Conference since and also emphasized that message at 10 Heart of America Grazing Conferences and three National Grazing Conferences. With all that emphasis, why do I bring this up again and even have the nerve to say “More Important Now than Ever”? Well, the short answer is “things are different now!”

Pre- And Post-Bronchodilator Lung Function As Predictors Of Mortality In The Lung Health Study, David M. Mannino, Enrique Diaz-Guzman, Sonia Buist

Preventive Medicine and Environmental Health Faculty Publications

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is supposed to be classified on the basis of post-bronchodilator lung function. Most longitudinal studies of COPD, though, do not have post-bronchodilator lung function available. We used pre-and post bronchodilator lung function data from the Lung Health Study to determine whether these measures differ in their ability to predict mortality.

METHODS: We limited our analysis to subjects who were of black or white race, on whom we had complete data, and who participated at either the 1 year or the 5 year follow-up visit. We classified subjects based on their baseline lung function, according …

Wolbachia Infections That Reduce Immature Insect Survival: Predicted Impacts On Population Replacement, Philip R. Crain, James W. Mains, Eunho Suh, Yunxin Huang, Philip H. Crowley, Stephen L. Dobson

Entomology Faculty Publications

BACKGROUND: The evolutionary success of Wolbachia bacteria, infections of which are widespread in invertebrates, is largely attributed to an ability to manipulate host reproduction without imposing substantial fitness costs. Here, we describe a stage-structured model with deterministic immature lifestages and a stochastic adult female lifestage. Simulations were conducted to better understand Wolbachia invasions into uninfected host populations. The model includes conventional Wolbachia parameters (the level of cytoplasmic incompatibility, maternal inheritance, the relative fecundity of infected females, and the initial Wolbachia infection frequency) and a new parameter termed relative larval viability (RLV), which is the survival of infected larvae relative to …

Pathology and Laboratory Medicine Faculty Publications

MicroRNAs (miRNAs) target mRNAs in human cells via complex mechanisms that are still incompletely understood. Using anti-Argonaute (anti-AGO) antibody co-immunoprecipitation, followed by microarray analyses and downstream bioinformatics, 'RIP-Chip' experiments enable direct analyses of miRNA targets. RIP-Chip studies (and parallel assessments of total input mRNA) were performed in cultured H4 cells after transfection with miRNAs corresponding to the miR-15/107 gene group (miR-103, miR-107, miR-16 and miR-195), and five control miRNAs. Three biological replicates were run for each condition with a total of 54 separate human Affymetrix Human Gene 1.0 ST array replicates. Computational analyses queried for determinants of miRNA:mRNA binding. The …

An Overview Of The U.S. Retirement Income Security System And The Principles And Values It Reflects, Kathryn L. Moore

Law Faculty Scholarly Articles

This article is designed to provide an overview of the U.S. retirement income security system from a comparative law perspective. Like many countries, the U.S. has a three tier pension or retirement income system, with the three tiers consisting of (1) Social Security, (2) employment-based pensions, and (3) individual savings. Thus, superficially, the U.S. retirement income security system resembles that of many around the world. Yet, in other ways, such as its focus on individual rights and responsibility, the U.S. system is unique.

The article begins by discussing the nine guiding principles of the U.S. Social Security system as identified …

Functional Plasticity Of Central Trpv1 Receptors In Brainstem Dorsal Vagal Complex Circuits Of Streptozotocin-Treated Hyperglycemic Mice, Andrea Zsombok, Muthu D. Bhaskaran, Hong Gao, Andrei V. Derbenev, Bret N. Smith

Physiology Faculty Publications

Emerging data indicate that central neurons participate in diabetic processes by modulating autonomic output from neurons in the dorsal motor nucleus of the vagus (DMV). We tested the hypothesis that synaptic modulation by transient receptor potential vanilloid type 1 (TRPV1) receptors is reduced in the DMV in slices from a murine model of type 1 diabetes. The TRPV1 agonist capsaicin robustly enhanced glutamate release onto DMV neurons by acting at preterminal receptors in slices from intact mice, but failed to do so in slices from diabetic mice. TRPV1 receptor protein expression in the vagal complex was unaltered. Brief insulin preapplication …

Degradable Cross-Linked Nanoassemblies As Drug Carriers For Heat Shock Protein 90 Inhibitor 17-N-Allylamino-17-Demethoxy-Geldanamycin, Andrei G. Ponta, Shanjida Akter, Younsoo Bae

Pharmaceutical Sciences Faculty Publications

Cross-linked nanoassemblies (CNAs) with a degradable core were prepared for sustained release of 17-N-allylamino-17-demethoxygeldanamycin (17-AAG), a potent inhibitor of heat shock protein 90 (HSP90). The particle size of CNAs ranged between 100 and 250 nm, which changed depending on the cross-linking yields and drug entrapment method. CNAs with a 1% cross-linking yield entrapped 17-AAG in aqueous solutions, yet degraded in 3 hrs. CNAs entrapped 5.2 weight% of 17-AAG as the cross-linking yield increased to 10%, retaining more than 80% of particles for 24 hrs. CNAs with drugs entrapped after the cross-linking reactions were 100 nm and remained stable in both …

Atypical Clinical And Diagnostic Features In Ménétrier's Disease In A Child, Michael Chung, Jaime Pittenger, Deborah Flomenhoft, Jeffrey Bennett, Eun Young Lee, Harohalli Shashidhar

Internal Medicine Faculty Publications

Ménétrier's disease is one of the rarest protein-losing gastropathies in childhood. It is characterized clinically by non-specific gastrointestinal symptoms and edema, biochemically by hypoalbuminemia, and pathologically by enlarged gastric folds. In adults, this disease can be devastating with significant morbidity and mortality. In childhood, it is a self-limiting, transient and benign illness. Its treatment is largely supportive with total parenteral nutrition (TPN) while oral intake is encouraged. Acute onset of vomiting in healthy school age children can be initially explained by acute viral gastroenteritis. However, persistent vomiting associated with hematemesis and severe abdominal pain should warrant further work-up. This case …

Rna Oxidation Adducts 8-Ohg And 8-Oha Change With Aβ42 Levels In Late-Stage Alzheimer's Disease, Adam M. Weidner, Melissa A. Bradley, Tina L. Beckett, Dana M. Niedowicz, Amy L.S. Dowling, Sergey V. Matveev, Harry Levine, Mark A. Lovell, M. Paul Murphy

Sanders-Brown Center on Aging Faculty Publications

While research supports amyloid-β (Aβ) as the etiologic agent of Alzheimer's disease (AD), the mechanism of action remains unclear. Evidence indicates that adducts of RNA caused by oxidation also represent an early phenomenon in AD. It is currently unknown what type of influence these two observations have on each other, if any. We quantified five RNA adducts by gas chromatography/mass spectroscopy across five brain regions from AD cases and age-matched controls. We then used a reductive directed analysis to compare the RNA adducts to common indices of AD neuropathology and various pools of Aβ. Using data from four disease-affected brain …

Sequential Alterations In Catabolic And Anabolic Gene Expression Parallel Pathological Changes During Progression Of Monoiodoacetate-Induced Arthritis, Jin Nam, Priyangi Perera, Jie Liu, Bjoern Rath, James Deschner, Robert Gassner, Timothy A. Butterfield, Sudha Agarwal

Physical Therapy Faculty Publications

Chronic inflammation is one of the major causes of cartilage destruction in osteoarthritis. Here, we systematically analyzed the changes in gene expression associated with the progression of cartilage destruction in monoiodoacetate-induced arthritis (MIA) of the rat knee. Sprague Dawley female rats were given intra-articular injection of monoiodoacetate in the knee. The progression of MIA was monitored macroscopically, microscopically and by micro-computed tomography. Grade 1 damage was observed by day 5 post-monoiodoacetate injection, progressively increasing to Grade 2 by day 9, and to Grade 3-3.5 by day 21. Affymetrix GeneChip was utilized to analyze the transcriptome-wide changes in gene expression, and …

Pipkiγ Regulates Focal Adhesion Dynamics And Colon Cancer Cell Invasion, Zhaofei Wu, Xiang Li, Manjula Sunkara, Heather Spearman, Andrew J. Morris, Cai Huang

Markey Cancer Center Faculty Publications

Focal adhesion assembly and disassembly are essential for cell migration and cancer invasion, but the detailed molecular mechanisms regulating these processes remain to be elucidated. Phosphatidylinositol phosphate kinase type Iγ (PIPKIγ) binds talin and is required for focal adhesion formation in EGF-stimulated cells, but its role in regulating focal adhesion dynamics and cancer invasion is poorly understood. We show here that overexpression of PIPKIγ promoted focal adhesion formation, whereas cells expressing either PIPKIγ^K188,200R or PIPKIγ^D316K, two kinase-dead mutants, had much fewer focal adhesions than those expressing WT PIPKIγ in CHO-K1 cells and HCT116 colon cancer cells. Furthermore, …

Activation Of Matrix Metalloproteinases Following Anti-Aβ Immunotherapy; Implications For Microhemorrhage Occurrence, Donna M. Wilcock, Dave Morgan, Marcia N. Gordon, Tiffany L. Taylor, Lisa A. Ridnour, David A. Wink, Carol A. Colton

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Anti-Aβ immunotherapy is a promising approach to the prevention and treatment of Alzheimer's disease (AD) currently in clinical trials. There is extensive evidence, both in mice and humans that a significant adverse event is the occurrence of microhemorrhages. Also, vasogenic edema was reported in phase 2 of a passive immunization clinical trial. In order to overcome these vascular adverse effects it is critical that we understand the mechanism(s) by which they occur.

METHODS: We have examined the matrix metalloproteinase (MMP) protein degradation system in two previously published anti-Aβ immunotherapy studies. The first was a passive immunization study in which …

The Importance Of Region And State Welfare Rules For Disconnected Single Mothers, Andrea Hetling

University of Kentucky Center for Poverty Research Discussion Paper Series

The proportion of low-income, single mothers not receiving public assistance or participating in the formal employment sector has approximately doubled over the past decade. Many of the currently debated policy options to support these families focus on state level programs. However, little is known about the relationships between state welfare program characteristics and disconnectedness. This project assesses the effect of state welfare rules on the likelihood of being disconnected from these two income sources. Using data from the Survey of Income and Program Participation and the Urban Institute‟s Welfare Rules Database, the current research compares the circumstances of these at-risk …
