Feasability Of Preventing Encrustation Of Urinary Catheters, J. M. Bibby, A. J. Cox, D. W. L. Hukins

Cells and Materials

Colonization of urinary catheters by bacteria which produce urease leads to an increase in urine pH, followed by deposition of the minerals struvite and hydroxyapatite. Adhesion of these encrusting deposits can be reduced, but not prevented, by using catheters with a smooth surface finish. Chemical methods for preventing encrustation are not completely satisfactory. A better way of preventing encrustation would be to prevent colonization of the catheter by bacteria. This might be achieved by controlled release of antimicrobial agents directly into the urine from the catheter itself. Preliminary experiments have demonstrated the feasibility of controlled release from solid silicone. However, …

Differential Modulation Of Human Glutamate Transporter Subtypes By Arachidonic Acid, Noa Zerangue, Jeffrey L. Arriza, Susan G. Amara, Michael Kavanaugh

Biomedical and Pharmaceutical Sciences Faculty Publications

Arachidonic acid has been proposed to be a messenger molecule released following synaptic activation of glutamate receptors and during ischemia. Here we demonstrate that micromolar levels of arachidonic acid inhibit glutamate uptake mediated by EAAT1, a human excitatory amino acid transporter widely expressed in brain and cerebellum, by reducing the maximal transport rate approximately 30%. In contrast, arachidonic acid increased transport mediated by EAAT2, a subtype abundantly expressed in forebrain and midbrain, by causing the apparent affinity for glutamate to increase more than 2-fold. The results demonstrate that the response of different glutamate transporter subtypes to arachidonic acid could influence …

A Family Of Putative Receptor-Adenylate Cyclases From Leishmania Donovani, Marco A. Sanchez, David Zeoli, Elizabeth M. Klamo, Michael Kavanaugh, Scott M. Landfear

Biomedical and Pharmaceutical Sciences Faculty Publications

Leishmania parasites are exposed to pronounced changes in their environment during their life cycle as they migrate from the sandfly midgut to the insect proboscis and then into the phagolysosomes of the vertebrate macrophages. The developmental transformations that produce each life cycle stage of the parasite may be signaled in part by binding of environmental ligands to receptors which mediate transduction of extracellular signals. We have identified a family of five clustered genes in Leishmania donovani which may encode signal transduction receptors. The coding regions of two of these genes, designated rac-A and rac-B, have been sequenced and shown …

Constitutive Ion Fluxes And Substrate Binding Domains Of Human Glutamate Transporters, Robert J. Vandenberg, Jeffrey L. Arriza, Susan G. Amara, Michael Kavanaugh

Biomedical and Pharmaceutical Sciences Faculty Publications

Application of L-glutamate activates ionic currents in voltage-clamped Xenopus oocytes expressing cloned human excitatory amino acid transporters (EAATs). However, even in the absence of L-glutamate, the membrane conductance of oocytes expressing EAAT1 was significantly increased relative to oocytes expressing EAAT2 or control oocytes. Whereas transport mediated by EAAT2 is blocked by the non-transported competitive glutamate analog kainate (K = 14 μM), EAAT1 is relatively insensitive (K > 3 mM). Substitution of a block of 76 residues from EAAT2 into EAAT1, in which 18 residues varied from EAAT1, conferred high affinity kainate binding to EAAT1, and application of kainate to …

Dangerous Decisions: An Essay On The Mathematics Of Clinical Violence Prediction And Involuntary Hospitalization, Douglas Mossman Md

Faculty Articles and Other Publications

This Article has two major purposes. First, it provides a mathematical
description of an ideal procedure for making clinical decisions about patients'
future violence, a description that provides a context for evaluating clinicians'
"dangerousness decisions." For purposes of illustration, the Article uses a specific clinical situation-deciding whether to hospitaize involuntarily a patient
based on his risk of harming another. The Article argues that the decision
involves balancing potential risks to third parties (often the patient's family
members) with the "massive deprivation of liberty and other potential
harms to the patient that could result from confinement. The mathematical
description of the …

Morphine Taste Conditioning And Analgesia: Assessing Conditioned And Novelty-Induced Analgesia, Rick A. Bevins, Joanne M. Valone, Melinda C. Bradley, Michael T. Bardo

Department of Psychology: Faculty Publications

In previous work showing a taste-elicited decrease in pain sensitivity (J. S. Miller, K. S. Kelly, J. L. Neisewander, D. F. Mc- Coy, & M. T. Bardo, 1990), the rats (Rattus norvegicus) were always habituated to an inactive hot plate after each drug injection. The present report examined whether the analgesic response was a conditioned response to the taste or a response to the novelty of the hot plate resulting from morphine disrupting the habituation process. In 3 experiments, it was found that hot plate novelty was mainly responsible for the analgesic response. For example, increasing the number …

An Overview Of The Effectiveness And Efficiency Of Hiv Prevention Programs, D. R. Holtgrave, Noreen L. Qualls, J. W. Curran, Ronald O. Valdiserri, Mary Guinan, William C. Parra

School of Public Health Faculty Research

Because of the enormity of the HIV-AIDS epidemic and the urgency for preventing transmission, HIV prevention programs are a high priority for careful and timely evaluations. Information on program effectiveness and efficiency is needed for decision-making about future HIV prevention priorities. General characteristics of successful HIV prevention programs, programs empirically evaluated and found to change (or not change) high-risk behaviors or in need of further empirical study, and economic evaluations of certain programs are described and summarized with attention limited to programs that have a behavioral basis. HIV prevention programs have an impact on averting or reducing risk behaviors, particularly …

A Review Of The Utilization Of Emg Biofeedback, Jeanine Lee Forsgren

Physical Therapy Scholarly Projects

Electromyographic (EMG) biofeedback is gaining popularity as a treatment modality in physical therapy. It is used in the areas of neurological and orthopedic rehabilitation as well as injury prevention and performance improvement. The use of this modality can aid in the rehabilitation process by identifying weak muscles which need to be strengthened. Physical therapy also utilizes EMG biofeedback to identify and change movement patterns which may contribute to injury through the overuse or incorrect use of various muscles. EMG biofeedback is used to assist the patient in learning how to control muscular movement to correct the problems which are identified. …

Rabies--Epidemiology, Prevention, And Future Research, John W. Krebs, Mark L. Wilson, James E. Childs

Zoonotics and Wildlife Disease: Publications

Rabies is caused by a single-stranded, negative-sense RNA virus, maintained in nature by a variety of animal reservoirs. Rabies virus infects the central nervous system, resulting in progressive encephalopathy and ultimately death in an infected human. Globally, the risk of contracting rabies for humans is greatest in regions of the developing world where dog rabies is enzootic. Where rabies in dogs has been eliminated or otherwise controlled through vaccination programs, the disease can be maintained by wildlife. Wildlife primarily involved in maintenance of transmission cycles are carnivores and bats. Persons having frequent contact with wildlife, such as mammalogists, are at …

Rodent-Borne Hemorrhagic Fever Viruses: A Special Risk For Mammalogists?, James E. Childs, James N. Mills, Gregory E. Glass

Zoonotics and Wildlife Disease: Publications

We review two groups of taxonomically unrelated viruses that share similarities in host preference and transmission routes to humans and pose a risk for mammalogists working with rodents. The rodent-borne hemorrhagic fever viruses in the Arenaviridae and Bunyaviridae are widely distributed on most continents where rodents occur. Their geographic distribution usually exceeds the distribution of the recognized human diseases they cause and has resulted from either natural coevolutionary events or the dissemination of viral passengers traveling with introduced mammalian hosts. Diseases of humans caused by these agents are among the most severe and most frequently fatal of zoonotic diseases. These …

Site-Directed Mutagenesis Of Southern Bean Mosaic Virus (Cowpea Strain): In Search Of A Viral Protease, Alan Simmons

Masters Theses & Specialist Projects

The second and largest open reading frame within the southern bean mosaic virus (SBMV) genome encodes a 105 kDa polyprotein. Following translation, the polyprotein is cleaved to liberate various proteins necessary for SBMV replication. The elements within polyproteins of the picornavirus superfamily members have a conserved order: Vpg (viral protein, genome-linked)-protease-replicase. Amino acid sequence homologies indicate that the 105 kDa protein of SBMV contains a replicase very similar to those identified in polyproteins of the picorna-like viruses. The presence of a VPg covalently attached to the 5' end of the SBMV genome further suggests that SBMV may be considered a …

Bone Absorptiometry In Metabolic Bone Disease: Baseline Values And Long-Term Treatment With Calcitriol (Post-Menopausal Osteoporosis Versus Osteomalacia), A. Caniggia, B. Frediani

Cells and Materials

Total body bone absorptiometry reveals low mineral density in both postmenopausal osteoporosis and osteomalacia patients. The method was used to investigate the effect of calcitriol administration on patients suffering from one of these conditions. In osteomalacia, the administration of calcitriol resulted in a dramatic improvement in bone mineral density (sometimes up to 50% in 12 months), indicating the rapid mineralization of previously uncalcified bone tissue as a result of the normalization of the Ca x P product. In osteoporosis a similar treatment was seen to halt the progressive decrease in bone mineral levels and sometimes resulted in minor increases in …

Some Observations On The Structure Of Encrusting Biofilms Of Proteus Mirabilis On Urethral Catheters, C. Winters, D. J. Stickler, N. S. Howe, T. J. Williams, N. Wilkinson, C. J. Buckley

Cells and Materials

A physical model of the bladder has been used to study the process of urinary catheter encrustation. Techniques have been devised for the preparation of sections through these encrustations in situ on the luminal surfaces of catheters and for mapping the distribution of calcium and magnesium in the biofilms. Transmission electron microscopy on these sections showed struvite-like crystals lying in the matrix and in direct contact with the catheter surface. Calcium phosphate ("bioapatite") was distributed throughout the film and many of these amorphous particles appear to have cells at their cores. Freeze-substituted sections of biofilms also showed electron dense materials …
