Manganese Toxicokinetics At The Blood-Brain Barrier, Robert A. Yokel, Janelle S. Crossgrove

Pharmaceutical Sciences Reports

Increased manganese (Mn) use in manufacturing and in gasoline has raised concern about Mn-induced parkinsonism. Previous research indicated carrier-mediated brain entry but did not assess brain efflux.

Using in situ rat brain perfusion, we studied influx across the blood-brain barrier (BBB) of three predominant plasma Mn species available to enter the brain: Mn²⁺, Mn citrate, and Mn transferrin. Our results suggested transporter-mediated uptake of these species. The uptake rate was greatest for Mn citrate. Our results using the brain efflux index method suggested that diffusion mediates distribution from rat brain to blood.

To characterize the carriers mediating brain …

We have investigated the detection, confirmation, and metabolism of the beta-adrenergic agonist ractopamine administered as Paylean to the horse. A Testing Components Corporation enzyme-linked imunosorbent assay (ELISA) kit for ractopamine displayed linear response between 1.0 and 100 ng/ml, with an 1-50 of 10 ng/ml, and an effective screening limit of detection of 50 ng/mL. The kit was readily able to detect ractopamine equivalents in unhydrolyzed urine up to 24 h following a 300-mg oral dose. Gas chromatography-mass spectrometry (GC-MS) confirmation comprised glucuronidase treatment, solid-phase extraction, and trimethylsilyl derivatization, with selected-ion monitoring of ractopamine-tris(trimethylsilane) (TMS) m/z 267, 250, 179, and 502 …

Development Of A Method For The Detection And Confirmation Of The Alpha-2 Agonist Amitraz And Its Major Metabolite In Horse Urine, A. F. Lehner, C. G. Hughes, W. Karpiesiuk, J Daniel Harkins, L. Dirikolu, Jeffrey M Bosken, Fernanda Camargo, J. Boyles, A. Troppmann, W. E. Woods, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Amitraz (N′-(2,4-dimethylphenyl)-N-[[(2,4-dimethylphenyl)imino] methyl]-N-methyl-methanimidamide) is an alpha-2 adrenergic agonist used in veterinary medicine primarily as a scabicide- or acaricide-type insecticide. As an alpha-2 adrenergic agonist, it also has sedative/tranquilizing properties and is, therefore, listed as an Association of Racing Commissioners International Class 3 Foreign Substance, indicating its potential to influence the outcome of horse races. We identified the principal equine metabolite of amitraz as N-2,4-dimethylphenyl-N′-methylformamidine by electrospray ionization(+)-mass spectrometry and developed a gas chromatographic-mass spectrometric (GC-MS) method for its detection, quantitation, and confirmation in performance horse regulation. The GC-MS method involves derivatization with t-butyldimethylsilyl groups; selected ion monitoring (SIM) of m/z …

A Gc-Ms Method For The Determination Of Isoxsuprine In Biological Fluids Of The Horse Utilizing Electron Impact Ionization, Jeffrey M Bosken, A. F. Lehner, C. G. Hughes, W. E. Woods, F. C. Camargo, J. D. Harkins, J. Boyles, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Isoxsuprine is used to treat navicular disease and other lower-limb problems in the horse. Isoxsuprine is regulated as a class 4 compound by the Association of Racing Commissioners, International (ARCI) and, thus, requires regulatory monitoring. A gas chromatography-mass spectrometry method utilizing electron impact ionization was developed and validated for the quantitation of isoxsuprine in equine plasma or equine urine. The method utilized robotic solid-phase extraction and tri-methyl silyl ether products of derivatization. Products were bis-trimethylsilyl (TMS) isoxsuprine and tris-TMS ritodrine, which released intense quantifier ions m/z 178 for isoxsuprine and m/z 236 for ritodrine that were products of C-C cleavage. …

The Mare Reproductive Loss Syndrome And The Eastern Tent Caterpillar Ii: A Toxicokinetic/Clinical Evaluation And A Proposed Pathogenesis: Septic Penetrating Setae, Thomas Tobin, J. Daniel Harkins, John Ford Roberts, Patricia W. Vanmeter, Tara A. Fuller

Maxwell H. Gluck Equine Research Center Faculty Publications

Reviewing the mare reproductive loss syndrome (MRLS), it is proposed that the fundamental mechanism of this syndrome, which includes early fetal loss, late fetal loss, uveitis, pericarditis, and encephalitis, is tissue penetration by septic barbed setal fragments (septic penetrating setae) from Eastern tent caterpillars (Malacosoma americanum). Once ingested, these barbed setal fragments migrate through moving tissues, followed by rapid hematogenous spread of bacteria, bacterial emboli, and/or septic fragments of setae (septic penetrating setal emboli), collectively referred to as septic materials. Pathogenic bacteria, therefore, enter the horse as hitchhikers on or in the caterpillar setal fragments, and MRLS is caused by …

Co-Regulation Of Expression Of Phase Ii Metabolizing Enzymes And Multidrug Resistance-Associated Protein 2, Viviana A. Catania, Enrique J. Sánchez Pozzi, Marcelo G. Luquita, María L. Ruiz, Silvina S. M. Villanueva, Brett Jones, Aldo D. Mottino

Toxicology and Cancer Biology Faculty Publications

Treatment of experimental animals with prototypical enzyme inducers represents a useful tool to characterize the role of different isozymes in drug metabolism and to improve our knowledge on factors regulating their synthesis at the transcriptional level. The effect of model enzyme inducers on phase II (conjugating) enzyme families, including UDP-glucuronosyltransferase’s and glutathione-S-transferase’s, has been well characterized in rodent liver. More recently, the effect of inducers on the expression of canalicular multidrug resistance-associated protein 2 (Mrp2) has been focused upon. The identification of a number of conjugated drugs as Mrp2 substrates suggests that both the conjugation and transport systems act coordinately …

The results revealed three substantially overlapping subgroups for both alcohol and marijuana: early onset, late onset, and nonuser. Although the general patterns of which dependent variables were related to group were similar for alcohol and marijuana, a closer examination revealed …

When The Safety Net Fails: An Analysis Of Alternative Long-Term Care Services In Kentucky, Suzanne Dale

MPA/MPP/MPFM Capstone Projects

The Problem

In early 2003, the Kentucky Cabinet for Health Services, faced with a $450 million Medicaid shortfall, implemented several cost-cutting measures to the Medicaid program. The most visible measure included new stricter medical eligibility requirements for long-term care programs. As a result of these new requirements, approximately 2,813 elderly and disabled Kentuckians were denied services in Kentucky’s Aged/Disabled Home and Community-Based Waiver Program, a Medicaid program that provides long-term care services in people’s homes and in community-settings. The Cabinet for Health Services claimed that those who lost home and community-based Medicaid services could receive care through alternative state programs. …

Transgenic Mice Expressing Lipoprotein Lipase In Adipose Tissue: Absence Of The Proximal 3′-Untranslated Region Causes Translational Upregulation, Lori L. Hensley, Gouri Ranganathan, Elke M. Wagner, Brian D. Wells, Joseph C. Daniel, Diane Vu, Clay F. Semenkovich, Rudolf Zechner, Philip A. Kern

Clinical and Translational Science Faculty Publications

Lipoprotein lipase (LPL) is a key enzyme in lipoprotein and adipocyte metabolism. Defects in LPL can lead to hypertriglyceridemia and the subsequent development of atherosclerosis. The mechanisms of regulation of this enzyme are complex and may occur at multiple levels of gene expression. Because the 3′-untranslated region (UTR) is involved in LPL translational regulation, transgenic mice were generated with adipose tissue expression of an LPL construct either with or without the proximal 3′-UTR and driven by the aP2 promoter. Both transgenic mouse colonies were viable and expressed the transgene, resulting in a 2-fold increase in LPL activity in white adipose …

Hypoxia-induced VEGF governs both physiological retinal vascular development and pathological retinal neovascularization. In the current paper, the mechanisms of physiological and pathological neovascularization are compared and contrasted. During pathological neovascularization, both the absolute and relative expression levels for VEGF₁₆₄ increased to a greater degree than during physiological neovascularization. Furthermore, extensive leukocyte adhesion was observed at the leading edge of pathological, but not physiological, neovascularization. When a VEGF₁₆₄-specific neutralizing aptamer was administered, it potently suppressed the leukocyte adhesion and pathological neovascularization, whereas it had little or no effect on physiological neovascularization. In parallel experiments, genetically altered VEGF_{164 …}
