Microbiology, Immunology, and Molecular Genetics Faculty Publications

The pathogenic spirochete Leptospira interrogans disseminates throughout its hosts via the bloodstream, then invades and colonizes a variety of host tissues. Infectious leptospires are resistant to killing by their hosts' alternative pathway of complement-mediated killing, and interact with various host extracellular matrix (ECM) components. The LenA outer surface protein (formerly called LfhA and Lsa24) was previously shown to bind the host ECM component laminin and the complement regulators factor H and factor H-related protein-1. We now demonstrate that infectious L. interrogans contain five additional paralogs of lenA, which we designated lenB, lenC, lenD, lenE and lenF …

Transcriptional Control Of Vascular Smooth Muscle Cell Proliferation By Peroxisome Proliferator-Activated Receptor-Γ: Therapeutic Implications For Cardiovascular Diseases, Florence Gizard, Dennis Bruemmer

Internal Medicine Faculty Publications

Proliferation of vascular smooth muscle cells (SMCs) is a critical process for the development of atherosclerosis and complications of procedures used to treat atherosclerotic diseases, including postangioplasty restenosis, vein graft failure, and transplant vasculopathy. Peroxisome proliferator-activated receptor (PPAR) gamma is a member of the nuclear hormone receptor superfamily and the molecular target for the thiazolidinediones (TZD), used clinically to treat insulin resistance in patients with type 2 diabetes. In addition to their efficacy to improve insulin sensitivity, TZD exert a broad spectrum of pleiotropic beneficial effects on vascular gene expression programs. In SMCs, PPARgamma is prominently upregulated during neointima formation …

Induction Of Insulin Secretion In Engineered Liver Cells By Nitric Oxide, Latha Muniappan, Sabire Özcan

Molecular and Cellular Biochemistry Faculty Publications

BACKGROUND: Type 1 Diabetes Mellitus results from an autoimmune destruction of the pancreatic beta cells, which produce insulin. The lack of insulin leads to chronic hyperglycemia and secondary complications, such as cardiovascular disease. The currently approved clinical treatments for diabetes mellitus often fail to achieve sustained and optimal glycemic control. Therefore, there is a great interest in the development of surrogate beta cells as a treatment for type 1 diabetes. Normally, pancreatic beta cells produce and secrete insulin only in response to increased blood glucose levels. However in many cases, insulin secretion from non-beta cells engineered to produce insulin occurs …

Osteopontin Mediates Obesity-Induced Adipose Tissue Macrophage Infiltration And Insulin Resistance In Mice, Takashi Nomiyama, Diego Perez-Tilve, Daisuke Ogawa, Florence Gizard, Yue Zhao, Elizabeth B. Heywood, Karrie L. Jones, Ryuzo Kawamori, Lisa A. Cassis, Matthias H. Tschöp, Dennis Bruemmer

Internal Medicine Faculty Publications

Obesity is associated with a state of chronic, low-grade inflammation characterized by abnormal cytokine production and macrophage infiltration into adipose tissue, which may contribute to the development of insulin resistance. During immune responses, tissue infiltration by macrophages is dependent on the expression of osteopontin, an extracellular matrix protein and proinflammatory cytokine that promotes monocyte chemotaxis and cell motility. In the present study, we used a murine model of diet-induced obesity to examine the role of osteopontin in the accumulation of adipose tissue macrophages and the development of insulin resistance during obesity. Mice exposed to a high-fat diet exhibited increased plasma …

Characterization Of The Equine 2'-5' Oligoadenylate Synthetase 1 (Oas1) And Ribonuclease L (Rnasel) Innate Immunity Genes, Jonathan J. Rios, Andrey A. Perelygin, Maureen T. Long, Teri L. Lear, Andrey A. Zharkikh, Margo A. Brinton, David L. Adelson

Veterinary Science Faculty Publications

BACKGROUND: The mammalian OAS/RNASEL pathway plays an important role in antiviral host defense. A premature stop-codon within the murine Oas1b gene results in the increased susceptibility of mice to a number of flaviviruses, including West Nile virus (WNV). Mutations in either the OAS1 or RNASEL genes may also modulate the outcome of WNV-induced disease or other viral infections in horses. Polymorphisms in the human OAS gene cluster have been previously utilized for case-control analysis of virus-induced disease in humans. No polymorphisms have yet been identified in either the equine OAS1 or RNASEL genes for use in similar case-control studies.

Azithromycin In The Extremely Low Birth Weight Infant For The Prevention Of Bronchopulmonary Dysplasia: A Pilot Study, Hubert O. Ballard, Michael I. Anstead, Lori A. Shook

Pediatrics Faculty Publications

BACKGROUND: Azithromycin reduces the severity of illness in patients with inflammatory lung disease such as cystic fibrosis and diffuse panbronchiolitis. Bronchopulmonary dysplasia (BPD) is a pulmonary disorder which causes significant morbidity and mortality in premature infants. BPD is pathologically characterized by inflammation, fibrosis and impaired alveolar development. The purpose of this study was to obtain pilot data on the effectiveness and safety of prophylactic azithromycin in reducing the incidence and severity of BPD in an extremely low birth weight (< or = 1000 grams) population.

METHODS: Infants < or = 1000 g birth weight admitted to the University of Kentucky Neonatal Intensive Care Unit (level III, regional referral center) from 9/1/02-6/30/03 were eligible for this pilot study. The pilot study was double-blinded, randomized, and placebo-controlled. Infants were randomized to treatment or placebo within 12 hours of beginning mechanical ventilation (IMV) and within 72 hours of birth. The treatment group received azithromycin 10 mg/kg/day for 7 days followed by 5 mg/kg/day for the duration of the study. Azithromycin or placebo was continued until the infant no longer required IMV or supplemental oxygen, to a maximum of 6 weeks. Primary endpoints were incidence of BPD as defined by oxygen requirement at 36 weeks gestation, post-natal steroid use, days of IMV, and mortality. Data was analyzed by intention to treat using Chi-square and ANOVA.

RESULTS: A total of 43 extremely premature infants were enrolled in this pilot study. Mean gestational age and …

Improve Safety Of Workers During Highway Construction And Maintenance, Donn E. Hancher, Kenneth Bussey, Robin Meagher, Jonathan Ross, Kristin Smith

Kentucky Transportation Center Research Report

There is an inherent risk of injury or fatality in all occupations. Even secretarial occupations face jobsite hazards such as carpal tunnel and back injury. The nature of the construction industry combined with the required physical demand and rigorous work processes, make it an industry with higher risk of injury or fatality. In an effort to decrease that inbuilt jobsite risk that construction workers face, this study will analyze the current best safety practices, examine new safety technologies, and collaborate with construction workers themselves to gain a better perspective of what jobsite hazards they face.

Specifically, this study will focus …

Physics and Astronomy Faculty Publications

Aims. We present a comparison between independent computer codes, modeling the physics and chemistry of interstellar photon dominated regions (PDRs). Our goal was to understand the mutual differences in the PDR codes and their effects on the physical and chemical structure of the model clouds, and to converge the output of different codes to a common solution.

Methods. A number of benchmark models have been created, covering low and high gas densities n = 10³,10^5.5 cm^-3 and far ultraviolet intensities χ = 10, 10⁵ in units of the Draine field (FUV: 6 < h_ν < 13.6 eV). The benchmark models were computed in two ways: one set assuming constant temperatures, thus testing the consistency of the chemical network and photo-processes, and a second set determining the temperature self consistently by solving the thermal balance, thus testing the modeling of the heating and cooling mechanisms accounting for the detailed energy balance throughout the clouds.

Physiology Faculty Publications

Protease inhibitors, as part of highly active anti-retroviral therapy (HAART), have significantly increased the lifespan of human immunodeficiency virus (HIV) infected patients. Several deleterious side effects including dyslipidemia and lipodystrophy, however, have been observed with HAART. Women are at a higher risk of developing adipose tissue alterations and these alterations have different characteristics as compared to men. We have previously demonstrated that in mice the HIV protease inhibitor, ritonavir, caused a reduction in weight gain in females, but had no effect on male mice. In the present study, we examined the potential causes of this difference in weight gain. Low-density …

Conspiracy Theories: Is There A Place For Civil Conspiracy In Products Liability Litigation?, Richard C. Ausness

Law Faculty Scholarly Articles

A civil conspiracy is a group of two or more persons acting together to achieve an unlawful objective or to achieve a lawful objective by unlawful or criminal means. During the past two decades, plaintiffs have brought numerous civil conspiracy claims against product manufacturers. The defendants in these cases have included manufacturers or producers of tobacco products, asbestos, pharmaceuticals, lead-based paint, multi-rim truck wheels, and gasoline additives. Surprisingly, less than half of the civil conspiracy claims have made it to trial. This unimpressive success rate suggests that courts are not very receptive to civil conspiracy claims even when there is …

Phase I And Phase Ii Ocular Metabolic Activities And The Role Of Metabolism In Ophthalmic Prodrug And Codrug Design And Delivery, Abeer M. Al-Ghananeem, Peter A. Crooks

Pharmaceutical Sciences Faculty Publications

While the mammalian eye is seldom considered an organ of drug metabolism, the capacity for biotransformation is present. Compared to the liver, the metabolic capabilities of the eye are minuscule; however, phase I and phase II metabolic activities have been detected in various ocular structures. The careful consideration of ocular tissue metabolic processes within the eye has important implications for controlling the detoxification of therapeutic agents and for providing the potential for site-specific bio-activation of certain drug molecules, thus enabling significant improvements in drug efficacy and the minimization of side-effect from either local or systemic drug delivery to the eye. …

Loline Alkaloid Gene Clusters Of The Fungal Endophyte Neotyphodium Uncinatum, Christopher L. Schardl, Heather H. Wilkinson, Martin J. Spiering

Plant Pathology Faculty Patents

Loline alkaloids (LA), which are 1-aminopyrrolizidines with an oxygen bridge, are produced by Epichloë (anamorph=Neotyphodium) species, endophytes of grasses. LA are insecticidal, thus helping protect host plants from insect herbivory. Suppression subtractive hybridization PCR was used to isolate transcripts up-regulated during loline alkaloid production in cultures of Neotyphodium uncinatum. Subtracted cDNAs were cloned, and a λ-phage cDNA library from an LA-expressing N. uncinatum culture was screened with subtracted cDNA. In BLAST searches, several cDNAs identified had sequence similarities to aspartate kinases, and another with O-acetylhomoserine-(thiol)lyase. Differential expression of these two genes in LA-producing cultures of N. uncinatum …
