Cardiovascular Tolerance And Safety Of Intravenous Lidocaine In The Broiler Chicken (Gallus Gallus Domesticus), Joao Manuel Lemos Brandao Jan 2014

Cardiovascular Tolerance And Safety Of Intravenous Lidocaine In The Broiler Chicken (Gallus Gallus Domesticus), Joao Manuel Lemos Brandao

LSU Master's Theses

Lidocaine, an amide local anesthetic agent, is commonly used in mammals, including humans. There is a general assumption that birds are more sensitive to lidocaine than mammals. Relatively low doses of lidocaine have been suggested to cause toxic effects in birds. While this information appears to be anecdotal, it has been perpetuated in the literature. The overall objective of this thesis research was to determine the tolerance and safety of intravenous lidocaine in broiler chickens. To assess the cardiovascular effects of lidocaine, relative changes on heart rate and mean blood pressure were calculated. Clinically significant cardiovascular effects were defined as …


Evaluating The Effects Of Dialect On Kindergartners' Use Of Three Grammatical Structures In Narratives, Andromeda Patrice Love Jan 2014

Evaluating The Effects Of Dialect On Kindergartners' Use Of Three Grammatical Structures In Narratives, Andromeda Patrice Love

LSU Master's Theses

The aim of this study was to determine if dialect status has an effect on the frequency at which kindergarteners produce nonmainstream English markings for regular third person, IS and ARE, and regular past tense when producing oral narratives. Specifically, I wished to determine if child speakers of African American English (AAE) and child speakers of Southern White English (SWE) mark these structures with nonmainstream English forms at different rates. The narrative data came from language samples that had been previously collected from twenty kindergarten speakers of AAE and twenty kindergarten speakers of SWE. All of the children were recruited …


The Effects Of Using Morphophonic Faces As A Method For Teaching Sight Words To Low-Performing Kindergartners, Ashley Alexandra Brown Jan 2014

The Effects Of Using Morphophonic Faces As A Method For Teaching Sight Words To Low-Performing Kindergartners, Ashley Alexandra Brown

LSU Master's Theses

Five kindergarten subjects who had no known disabilities, but were identified as low beginning readers received intervention using both Plain Word Cards (PWC) and pictured word cards, termed MorphoPhonic Faces (MPF). A group of eight words were presented as printed word cards and a comparable group of eight words were presented as MPF. Results revealed that MPF did not hold an advantage for learning and retaining sight words compared to the plain print words. Improvements in sight word training corresponded in time with improved skills underlying the alphabetic principle, including phonological awareness skills and letter-sound learning, as well as emerging …


"Mais, You Talk Like Me? /Ju Ra:/": Kindergarteners' Use Of Five Cajun English Phonological Features, Hannah Joy Smitherman Jan 2014

"Mais, You Talk Like Me? /Ju Ra:/": Kindergarteners' Use Of Five Cajun English Phonological Features, Hannah Joy Smitherman

LSU Master's Theses

Cajun English (CE) is an understudied dialect that is spoken in and around the Acadian triangle of Louisiana. Of the studies that exist, almost all have been completed with adults. The purpose of the current study was to determine if children whose parents have identified their family as Cajun use five phonological features of CE (/t, d/ for /θ, ð/, nonaspirated /p, t, k/, heavy vowel nasalization, monophthongization, and glide weakening on vowels) more frequently than those identified as non-Cajun. The participants were 11 kindergarteners who were identified as Cajun or non-Cajun and who resided in Assumption Parish in rural …


Stroke And Aphasia Quality Of Life Scale-39: Investigating Preliminary Content Validity Of Picture Representations By People With Mild To Moderate Aphasia, Lea Jane Heise-Jensen Jan 2014

Stroke And Aphasia Quality Of Life Scale-39: Investigating Preliminary Content Validity Of Picture Representations By People With Mild To Moderate Aphasia, Lea Jane Heise-Jensen

LSU Master's Theses

Speech-language pathologists must consider the clients’ quality of life (QoL) to provide effective and meaningful evidence-based treatment (ASHA, 2005). Quality of life assessment goes beyond language impairments and is often a key part of planning intervention. However, few QoL measures exist for people with aphasia (PWA). The Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39; Hilari, 2003) is one of the few valid and reliable measures used to assess QoL in people with mild to moderate aphasia. However, the validity and reliability of the SAQOL-39 has not been established for individuals with severe aphasia who are unable to read and …


Characterization Of Ige-Mediated Cutaneous Immediate And Late-Phase Reactions In Non-Allergic Horses, Michelle Woodward Jan 2014

Characterization Of Ige-Mediated Cutaneous Immediate And Late-Phase Reactions In Non-Allergic Horses, Michelle Woodward

LSU Master's Theses

ABSTRACT Objectives – To characterize the response of horse skin following intradermal injection of polyclonal rabbit anti-canine IgE (anti-IgE) and rabbit immunoglobulin G (IgG) in an attempt to develop a model of equine allergic skin disease. Study design - In vivo study. Animals – 10 Adult Thoroughbred horses. Methods –Horses were injected intradermally with one of two different concentrations of anti-IgE and rabbit immunoglobulin G (IgG). Wheal measurements and injection site biopsies were obtained before and 20 min, 6 hr, 24 hr, and 48 hr after injection. Tissue sections were stained with Hematoxylin and Eosin, Luna, and Toluidine Blue. Immunohistochemistry …


The Role Of Monocyte Chemoattractant Protein-1 In Innate Immunity Against Methicillin Resistant Staphylococcus Aureus Pneumonia, Mary Katherine Leissinger Jan 2014

The Role Of Monocyte Chemoattractant Protein-1 In Innate Immunity Against Methicillin Resistant Staphylococcus Aureus Pneumonia, Mary Katherine Leissinger

LSU Master's Theses

Monocyte chemoattractant protein-1 is critical for monocyte recruitment to the lungs in response to bacterial infection. MCP-1 is also essential for protective neutrophil recruitment to the lungs during Escherichia coli and Klebsiella pneumoniae infection. Staphylococcus aureus pneumonia, specifically strain USA300, carries a high morbidity and mortality rate and is an important pathogen in hospital/ventilator and community acquired pneumonia. In the current study, we investigated the role of MCP-1 in pulmonary innate immunity to S. aureus in C57Bl/6, MCP-1-/- and MCP-1 AB blocked mice. As compared to C57Bl/6, MCP-1-/- mice showed increased concentrations of neutrophils in the airways and lung parenchyma …


Improving The Reliability Of Caregivers' Responses On The Infant-Toddler Meaningful Auditory Integration Scales (It-Mais) Via Video, Chelsi Meagan Gibbons Jan 2014

Improving The Reliability Of Caregivers' Responses On The Infant-Toddler Meaningful Auditory Integration Scales (It-Mais) Via Video, Chelsi Meagan Gibbons

LSU Master's Theses

The IT-MAIS is a caregiver-report tool used to assess a child’s functional auditory development pre- and post-implantation (Zimmerman-Phillips, et al., 2001) and as a measure of functional auditory behaviors in studies exploring cochlear implant (CI) candidacy (Barker, Kenworthy, & Walker, 2011; Franz 2002; Osberger, Zimmerman-Phillips, & Koch, 2002). However it lacks psychometric analysis of its overall reliability and validity, which are essential in determining the strength of the IT-MAIS’ conclusions in determining the direction of a child’s clinical intervention outcomes. Barker, Donovan, Schubert, and Walker (2013) showed in their longitudinal study that caregivers did not predictably respond to items from …


Autologous Adipose Derived Adult Multipotent Stromal Cells Alter The Porcine Systemic Immune And Bone Biomarkers Response To Cancellous Bone Xenografts, Jonathan Francis Bova Jan 2014

Autologous Adipose Derived Adult Multipotent Stromal Cells Alter The Porcine Systemic Immune And Bone Biomarkers Response To Cancellous Bone Xenografts, Jonathan Francis Bova

LSU Master's Theses

The use of a porcine model in assessing bone grafts in vivo is common when a large animal model is necessary. In this thesis we aimed to improve the porcine model of facial reconstruction through the use of a local anesthesia and novel methods of assessing the immune response to and bone forming ability of adult adipose derived mesenchymal stromal cells (ASC). The goals of the research were: 1) evaluate the effect of a bupivacaine mandibular nerve block on blood pressure (BP) and heart rate (HR) in response to surgical stimulation and the need for systemic analgesics postoperatively, 2) quantify …
