Anatomy And Three-Dimensional Reconstructions Of The Brain Of A Bottlenose Dolphin (Tursiops Truncatus) From Magnetic Resonance Images, Lori Marino, Keith D. Sudheimer, Timothy L. Murphy, Kristina K. Davis, D. Ann Pabst, William A. Mclellan, James K. Rilling, John I. Johnson

Veterinary Science and Medicine Collection

Cetacean (dolphin, whale, and porpoise) brains are among the least studied mammalian brains because of the formidability of collecting and histologically preparing such relatively rare and large specimens. Magnetic resonance imaging offers a means of observing the internal structure of the brain when traditional histological procedures are not practical. Furthermore, internal structures can be analyzed in their precise anatomic positions, which is difficult to accomplish after the spatial distortions often accompanying histological processing. In this study, images of the brain of an adult bottlenose dolphin, Tursiops truncatus, were scanned in the coronal plane at 148 antero-posterior levels. From these scans …

Ultrasound Based Quantitative Motion Measurement Using Speckle Size Estimation, James D. Hamilton, Larry Y. L. Mo, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

An ultrasound system determines the relative movement in a first direction (F1) of first matter, such as blood flow, and second matter, such as an artery wall, in a subject under study (S). A beam (B1) of ultrasound waves defining a plurality of beam positions (BP1 and BP2) and beam axes (A1 and A2) are moved in scan direction having components parallel to direction F1. First and second blocks of data representing the first and second matter, respectively, are generated. A processor (20) performs an estimation of speckle size on first data to obtain a first result, and performs analysis …

A Disengaging Metal Spike And Putting Green Quality, C. Jayne Brahler, Joe Macgowan, Marjorie Kapper, Katie Murphy, Mike Pequignot, Cristi Seidelson, Vicki Denlinger, Carrie Crites

Health and Sport Science Faculty Publications

Over the past few years, some disadvantages to alternative spikes have surfaced. The amount of damage to putting surfaces is in question, but the damage may not be noticed immediately, as it is with the conventional 8-mm length metal spike. The present study questions the effect of alternative spikes on putting green quality and ball roll.

Results Awareness of the role of folate in the prevention of birth defects rose by 8% in the first 6 months of the campaign (without health claims) and by 15% in the second half (when health claims were incorporated). Awareness of the recommendation to take folate before pregnancy rose from 21% …

The Standardized Fish Bioassay Procedure For Detecting And Culturing Actively Toxic Pfiesteria, Used By Two Reference Laboratories For Atlantic And Gulf Coast States, Joann M. Burkholder, Harold G. Marshall, David W. Seaborn, Nora J. Deamer-Melia

Biological Sciences Faculty Publications

In the absence of purified standards of toxins from Pfiesteria species, appropriately conducted fish bioassays are the "gold standard" that must be used to detect toxic strains of Pfiesteria slop. from natural estuarine water or sediment samples and to culture actively toxic Pfiesteria. In this article, we describe the standardized steps of our fish bioassay as an abbreviated term for a procedure that includes two sets of trials with fish, following the Henle-Koch postulates modified for toxic rather than infectious agents. This procedure was developed in 1991, and has been refined over more than 12 years of experience in …

Ipsilesional Biases In Saccades But Not Perception After Lesions Of The Human Inferior Parietal Lobule, Tony Ro, Chris Rorden, Jon Driver, Robert Rafal

Publications and Research

We examined the effects of chronic unilateral lesions to either the inferior parietal lobe, or to the dorsolateral prefrontal cortex including the frontal eye fields (FEFs), upon human visual perception and saccades in temporal-order-judgment (TOJ) tasks. Two visual events were presented on each trial, one in each hemifield at various stimulus onset asynchronies (SOAs). In the saccade task, patients moved their eyes to whichever stimulus attracted gaze first. In the perceptual-manual task, they pressed a button to indicate which stimulus was perceived first. Frontal patients showed appropriate TOJs for visual targets in both tasks. Parietal patients showed appropriate TOJs in …

The Toxoplasma Gondii Protein Rop2 Mediates Host Organelle Association With The Parasitophorous Vacuole Membrane, Anthony P. Sinai, Keith A. Joiner

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Toxoplasma gondii replicates within a specialized vacuole surrounded by the parasitophorous vacuole membrane (PVM). The PVM forms intimate interactions with host mitochondria and endoplasmic reticulum (ER) in a process termed PVM–organelle association. In this study we identify a likely mediator of this process, the parasite protein ROP2. ROP2, which is localized to the PVM, is secreted from anterior organelles termed rhoptries during parasite invasion into host cells. The NH₂-terminal domain of ROP2 (ROP2hc) within the PVM is exposed to the host cell cytosol, and has characteristics of a mitochondrial targeting signal. In in vitro assays, ROP2hc is …

Marek's Disease Virus (Mdv) Encodes An Interleukin-8 Homolog (Vil-8): Characterization Of The Vil-8 Protein And A Vil-8 Deletion Mutant Mdv, Mark S. Parcells, Su-Fang Lin, Robert L. Dienglewicz, Vladimir Majerciak, Dan R. Robinson, Hua-Chien Chen, Zining Wu, George R. Dubyak, Peter Brunovskis, Henry D. Hunt

Dartmouth Scholarship

Chemokines induce chemotaxis, cell migration, and inflammatory responses. We report the identification of an interleukin-8 (IL-8) homolog, termed vIL-8, encoded within the genome of Marek's disease virus (MDV). The 134-amino-acid vIL-8 shares closest homology to mammalian and avian IL-8, molecules representing the prototype CXC chemokine. The gene for vIL-8 consists of three exons which map to the BamHI-L fragment within the repeats flanking the unique long region of the MDV genome. A 0.7-kb transcript encoding vIL-8 was detected in an n-butyrate-treated, MDV-transformed T-lymphoblastoid cell line, MSB-1. This induction is essentially abolished by cycloheximide and herpesvirus DNA polymerase inhibitor phosphonoacetate, indicating …

Comparison Of The Quantification Of Caffeine In Human Plasma By Gas Chromatography And Elisa, A. B. Carregaro, W. E. Woods, Thomas Tobin, A. Queiroz-Neto

Veterinary Science Faculty Publications

In the present study we evaluated the precision of the ELISA method to quantify caffeine in human plasma and compared the results with those obtained by gas chromatography. A total of 58 samples were analyzed by gas chromatography using a nitrogen-phosphorus detector and routine techniques. For the ELISA test, the samples were diluted to obtain a concentration corresponding to 50% of the absorbance of the standard curve. To determine whether the proximity between the I₅₀ of the standard curve and that of the sample would bring about a more precise result, the samples were divided into three blocks according …

Effect Of A Single Amino Acid Change In Mhc Class I Molecules On The Rate Of Progression To Aids, Xiaojiang Gao, George W. Nelson, Peter Karacki, Maureen P. Martin, John Phair, Richard A. Kaslow, James J. Goedert, Susan Buchbinder, Keith Hoots, David Vlahov, Stephen J. O'Brien, Mary Carrington

Biology Faculty Articles

Background From studies of genetic polymorphisms and the rate of progression from human immunodeficiency virus type 1 (HIV-1) infection to the acquired immunodeficiency syndrome (AIDS), it appears that the strongest susceptibility is conferred by the major-histocompatibility-complex (MHC) class I type HLA-B*35,Cw*04 allele. However, cytotoxic T-lymphocyte responses have been observed against HIV-1 epitopes presented by HLA-B*3501, the most common HLA-B*35 subtype. We examined subtypes of HLA-B*35 in five cohorts and analyzed the relation of structural differences between HLA-B*35 subtypes to the risk of progression to AIDS. Methods Genotyping of HLA class I loci was performed for 850 patients who seroconverted and …

Studies On The Formation Of Dna-Cationic Lipid Composite Films And Dna Hybridization In The Composites, Murali Sastry, Vidya Ramakrishnan, Mrunalini Pattarkine, Krishna N. Ganesh

Faculty Works

The formation of composite films of double-stranded DNA and cationic lipid molecules (octadecylamine, ODA) and the hybridization of complementary single-stranded DNA molecules in such composite films are demonstrated. The immobilization of DNA is accomplished by simple immersion of a thermally evaporated ODA film in the DNA solution at close to physiological pH. The entrapment of the DNA molecules in the cationic lipid film is dominated by attractive electrostatic interaction between the negatively charged phosphate backbone of the DNA molecules and the protonated amine molecules in the thermally evaporated film and has been quantified using quartz crystal microgravimetry (QCM). Fluorescence studies …

Perceptions Of The Family Mealtime Environment And Adolescent Mealtime Behavior: Do Adults And Adolescents Agree?, Kerri N. Boutelle, Leslie A. Lytle, David M. Murray, Amanda Birnbaum, Mary Story

Department of Public Health Scholarship and Creative Works

The family mealtime environment has great potential to affect the eating behaviors of youth in the family. It is difficult to determine the important elements of a healthy mealtime environment because a valid assessment of the family environment is so difficult to obtain. The objective of this study is to examine the level of agreement between adult and adolescent perceptions of the family mealtime environment and adolescent mealtime behavior. A telephone survey was used to query adult and adolescent family members about how they perceive the family mealtime environment and the adolescent's mealtime behavior. A convenience sample of 282 adult/adolescent …

Magnetic Resonance Imaging And Three-Dimensional Reconstructions Of The Brain Of A Fetal Common Dolphin, Delphinus Delphis, Lori Marino, Timothy L. Murphy, Lyad Gozal, John I. Johnson

Veterinary Science and Medicine Collection

To demonstrate the kinds of data that can be obtained non-destructively and non-invasively from preserved museum specimens using modern imaging technology the head region of a whole body fetal specimen of the common dolphin, Delphinus delphis, aged 8–9 months post-conception, was scanned using Magnetic Resonance Imaging (MRI). Series of scans were obtained in coronal, sagittal and horizontal planes. A digital three-dimensional reconstruction of the whole brain was prepared from the coronal series of scans. Sectional areas and three-dimensional volumes were obtained of the cerebral hemispheres and of the brainstemplus-cerebellum. Neuroanatomical features identified in the scans include the major sulci of …

Evidence For Two Mechanisms Of Amino Acid Osmolyte Release From Hippocampal Slices, R. Franco, M. E. Torres-Marquez, H. Pasantes-Morales

School of Veterinary and Biomedical Sciences: Faculty Publications

A 30% decrease in osmolarity stimulated ³H-taurine, ³H-GABA and glutamate (followed as ³H-D-aspartate) efflux from rat hippocampal slices. ³H-taurine efflux was activated rapidly but inactivated slowly. It was decreased markedly by 100 μM 5-nitro-(3-phenylpropylamino) benzoic acid (NPPB) and 600 μM niflumic acid and inhibited strongly by tyrphostins AG18, AG879 and AG112 (25–100 μM), suggesting a tyrosine kinase-mediated mechanism. Hyposmolarity activated the mitogen-activated protein kinases (MAPK) extracellular-signal-related kinase-1/2 (ERK1/ERK2) and p38, but blockade of this reaction did not affect ³H-taurine efflux. Hyposmosis also activated phosphatidyl-inositide 3-kinase (PI3K) and its prevention by wortmannin (100 nM) essentially abolished …

Determinants Of Teachers' Intentions To Teach Physically Active Physical Education Classes, Jeffrey J. Martin, Pamela Hodges Kulinna, Robert C. Eklund, Brett Reed

Kinesiology, Health and Sport Studies

The purpose of the present investigation was to examine determinants of teachers' intentions to teach physically active physical education classes (i.e., spend at least 50% of class time with the students engaged in moderate to vigorous physical activity). Based on the theories of reasoned action, planned behavior, and self-efficacy, a model was examined hypothesizing that teachers' intentions were determined by subjective norm, attitude, perceived behavioral control, and self-efficacy. Using hierarchical regression analyses, the theories of reasoned action and planned behavior were supported by accounting for 65% of the variance in intention due to the main effects of attitude and subjective …

Developmental Coordination Disorder: A Discrete Disability, Beth P. Hands, Dawne Larkin

Health Sciences Papers and Journal Articles

Children with Developmental Coordination Disorder (DCD) have a motor learning disability that reduces their ability to interact with the environment and compromises their social and emotional development. Accordingly, these children should be given the extra assistance and consideration given to children with other learning difficulties. Even though many countries have well developed policies to support students at educational risk, children with movement difficulties are not widely considered to be members of this category. This paper argues for a change in education policy and practice in order to better support children with DCD or Motor Learning Disability (MLD). Improved teacher education …

Submerged And Solid-State Phytase Fermentation By Aspergillus Niger: Effects Of Agitation And Medium Viscosity On Phytase Production, Fungal Morphology And Inoculum Performance, Maria Papagianni, Sue E. Nokes, Keith Filer

Biosystems and Agricultural Engineering Faculty Publications

Qualitative relationships between agitation levels and medium viscosity, Aspergillus niger morphology and phytase production were investigated in submerged and solid-state fermentations. Overall phytase production increased with increasing shaker speeds from 150 to 300 rpm, although specific growth rates and phytase production rates were higher at 150 rpm for 72 h from inoculation. Fungal morphology was greatly influenced by agitation with the morphological forms of small pellets and entangled mycelia predominating at 150 rpm, while the free filamentous form was obtained at 300 rpm. Upon inoculation of SSF, increased productivities were obtained from inocula grown at 150 rpm. A shift towards …

Escherichia Coli O157:H7 In Free-Ranging Deer In Nebraska, David G. Renter, Jan M. Sargeant, Scott E. Hygnstrom, Jeff D. Hoffmann, Jerry R. Gillespie

School of Natural Resources: Faculty Publications

In order to determine the prevalence and distribution of the human pathogen, Escherichia coli O157:H7, in free-ranging deer, hunters were asked to collect and submit fecal samples from deer harvested during a regular firearm season (14–22 November 1998). Prior to the season, 47% of the hunters with permits in the southeastern Nebraska (USA) study area indicated a willingness to participate in the study. Approximately 25% of successful hunters in the area submitted deer fecal samples. Escherichia coli O157:H7 was cultured from four (0.25%) of 1,608 total samples submitted. All of the fecal samples that were properly identified (1,426) and all …

Dissection: The Scientific Case For Alternatives, Jonathan Balcombe

Experimentation Collection

This article presents the scientific argument that learning methods that replace traditional nonhuman animal-consumptive methods in life science education—so-called alternatives to dissection—are pedagogically sound and probably superior to dissection. This article focuses on the pedagogy, a learning method’s effectiveness for conveying knowledge.

Animal Research: A Review Of Developments, 1950–2000, Andrew N. Rowan, Franklin M. Loew

State of the Animals 2001

The third phase of the animal research debate started around 1950. After World War II the government became a major sponsor of scientific research, including biomedical research. The budget of the National Institutes of Health (NIH) grew dramatically and has continued to grow, with a few minor retrenchment periods, up to the present time (see Figure 1). This growth led to an enormous expansion in publicly funded research. In the private sector, the discovery of penicillin and streptomycin led to a tremendous expansion in pharmaceutical research and in the size of the prescription drug industry. These expansions in government funding …

Public Health Faculty Publications

To date, four of the eight cases of infection by Staphylococcus aureus with reduced susceptibility to vancomycin (vancomycin-intermediate S. aureus [VISA] or glycopeptideintermediate S. aureus [GISA]) have been reported in the United States (1-3). We report a fifth case of VISA infection in the United States, and the first to occur during home health-care therapy. While all previous VISA strains have been oxacillin resistant, one of the two VISA strains identified in this investigation was oxacillin susceptible.

Believability Of Anti-Drug Advertising As A Function Of Marijuana Usage Experience, Sandra C. Jones, John R. Rossiter

Faculty of Health and Behavioural Sciences - Papers (Archive)

Marijuana use is on the increase in Australia, particularly among teenagers. Information dissemination is likely to become the main vehicle for minimizing the harms associated with marijuana use, so there is a clear need to develop informative and convincing communication strategies to target young (potential and incipient) marijuana users. However, the Federal Government’s “zero tolerance” approach to drug use is accompanied by anti-drug messages that may lack credibility with young people who already use, or have used, marijuana. Cognitive dissonance theory, as well as research with warning labels on other products such as cigarettes, suggests that young people who currently …
