Inhibition Of Injury-Induced Cell Proliferation In The Dentate Gyrus Impairs Cognitive Recovery Following Traumatic Brain Injury, 2012 Virginia Commonwealth University
Inhibition Of Injury-Induced Cell Proliferation In The Dentate Gyrus Impairs Cognitive Recovery Following Traumatic Brain Injury, Teresa Daniels
Theses and Dissertations
Traumatic brain injury (TBI) induces a robust cellular proliferative response among neural stem/progenitor cells (NS/NPCs) in the dentate gyrus of the hippocampus. This proliferative effect is thought to contribute to the innate cognitive recovery observed following TBI. Inhibition of hippocampal neurogenesis impairs cognitive function. Furthermore, enhancement of injury-induced hippocampal neurogenesis via intraventricular administration of basic fibroblast growth factor (bFGF) improves cognitive function in animals following TBI. In this experiment, we investigated the direct association between injury-induced hippocampal neurogenesis and cognitive recovery utilizing an antimitotic agent, arabinofuranosyl cytidine (Ara-C). In this study, adult rats received a moderate lateral fluid percussion injury …
The Effect Of Minocycline Treatment On Cell Proliferation And Neurogenesis In The Hippocampus In Young And Aged Brains Following Traumatic Brain Injury, 2012 Virginia Commonwealth University
The Effect Of Minocycline Treatment On Cell Proliferation And Neurogenesis In The Hippocampus In Young And Aged Brains Following Traumatic Brain Injury, Ashley Harvin
Theses and Dissertations
Following traumatic brain injury, there is an enhanced cell proliferative and neurogenic response in the young adult hippocampus, which may be associated with innate cognitive recovery. However, in the aged brain, an increased level of inflammatory cell responses was observed following injury concomitant to decreased hippocampal neurogenesis and cognitive recovery in the aging population. This suggests that excessive inflammation produced in the injured aging brain has a detrimental effect on neurogenesis and cognitive function. In this study, we examined the effect of anti-inflammatory treatment with minocycline on cell proliferation and generation of new neurons in the dentate gyrus (DG) of …
The Role Of Sulfatide In The Development And Maintenance Of The Nodal And Paranodal Domains In The Peripheral Nervous System, 2012 Virginia Commonwealth University
The Role Of Sulfatide In The Development And Maintenance Of The Nodal And Paranodal Domains In The Peripheral Nervous System, Heather Herman
Theses and Dissertations
Sulfatide is a galactolipid and a major lipid component of the myelin sheath. Its production is catalyzed by the enzyme cerebroside sulfotransferase (CST). To determine the functions of sulfatide, the gene encoding CST was genetically disrupted resulting in mice incapable of sulfatide synthesis. Using these mice, it has been shown in the central nervous system (CNS) that sulfatide is essential for normal myelin synthesis and stability even though the onset of myelination is not impaired. Additionally, proper initial clustering of paranodal proteins and cluster maintenance of nodal proteins is impaired suggesting that paranodal domains are important for long-term node stability. …
Anatomy: The Relationship Between Internal And External Visualizations, 2012 The University of Western Ontario
Anatomy: The Relationship Between Internal And External Visualizations, Ngan T. Nguyen
Electronic Thesis and Dissertation Repository
This dissertation explored the relationship between internal and external visualizations and the implications of this relationship for comprehending visuospatial anatomical information. External visualizations comprised different computer representations of anatomical structures, including: static, animated, non-interactive, interactive, non-stereoscopic, and stereoscopic visualizations. Internal visualizations involved examining participants’ ability to apprehend, encode, and manipulate mental representations (i.e., spatial visualization ability or Vz). Comprehension was measured with a novel spatial anatomy task that involved mental manipulation of anatomical structures in three-dimensions and two-dimensional cross-sections. It was hypothesized that performance on the spatial anatomy task would involve a trade-off between internal and external visualizations available to …
Hearts And Minds: Examining The Evolution Of The Egyptian Excerebration And Evisceration Traditions Through The Impact Mummy Database, 2012 The University of Western Ontario
Hearts And Minds: Examining The Evolution Of The Egyptian Excerebration And Evisceration Traditions Through The Impact Mummy Database, Andrew D. Wade
Electronic Thesis and Dissertation Repository
Egyptian mummification and funerary rituals were a transformative process, making the deceased a pure being; free of disease, injury, and disfigurements, as well as ethical and moral impurities. Consequently, the features of mummification available to specific categories of individuals hold social and ideological significance. This study refutes long-held classical stereotypes, particularly dogmatic class associations; demonstrates the apocryphal nature of universal heart retention; and expands on the purposes of excerebration and evisceration implied by synthetic and radiological analyses.
Features of the embalming traditions, specifically the variable excerebration and evisceration traditions, represented the Egyptian view of death. Fine-grain analyses, through primary imaging …

Anatomy and Cell Biology Publications
Natural reward and drugs of abuse converge upon the mesolimbic system which mediates motivation and reward behaviors. Drugs induce neural adaptations in this system, including transcriptional, morphological, and synaptic changes, which contribute to the development and expression of drug-related memories and addiction. Previously, it has been reported that sexual experience in male rats, a natural reward behavior, induces similar neuroplasticity in the mesolimbic system and affects natural reward and drug-related behavior. The current study determined whether sexual experience causes long-lasting changes in mating, or ionotropic glutamate receptor trafficking or function in the nucleus accumbens (NAc), following 3 different reward abstinence …

T-Scores In African American Women, 2012 Mercy Hospital, Chicago, IL
T-Scores In African American Women, Catherine Meyer, Brooke L. Griffin, Kathy Komperda, Jill Borchert
Journal of Health Disparities Research and Practice
Many older bone densitometer (DXA) machines are programmed to calculate T-scores for African- American patients using peak African-American bone mass as reference standard.
This presents a problem because most data regarding fracture risk has been derived using Caucasian data (Binkley 2002). If the T-score for an African-American woman is calculated using a race-adjusted reference, the same absolute bone density will yield a lower T-score for an African- American than for a Caucasian woman. For this reason, the International Society for Clinical Densitometry has recommended that T-scores for all women, regardless of ethnicity, be calculated from Caucasian reference standards (ISCD 2007).

Physical Therapy Faculty Publications
Bmi-1, a polycomb transcriptional repressor, is implicated in cell cycle regulation and cell senescence. Its absence results in generalized astrogliosis and epilepsy during the postnatal development, but the underlying mechanisms are poorly understood. Here, we demonstrate the occurrence of oxidative stress in the brain of four-week-old Bmi-1 null mice. The mice showed various hallmarks of neurodegeneration including synaptic loss, axonal demyelination, reactive gliosis and brain mitochondrial damage. Moreover, astroglial glutamate transporters and glutamine synthetase decreased in the Bmi-1 null hippocampus, which might contribute to the sporadic epileptic-like seizures in these mice. These results indicate that Bmi-1 is required for maintaining …

Pubspectra - Open Data Access Fluorescence Spectra, George Mcnamara
The Internet is enabling greater access to spectral imaging publications, spectral graphs, and data than that was available a generation ago. The spectral imaging systems discussed in this issue of Cytometry work because reagent and hardware spectra are reproducible, reusable, and provide input to spectral unmixing and spectral components recognition algorithms. These spectra need to be readily available in order to determine what to purchase, how to use it, and what the output means. We refer to several commercially sponsored and academic spectral web sites and discuss our spectral graphing and data sites. Sites include fluorescent dye graph servers from …

The Expression Of Ecotropic Virus Integration Site-1 In Seven Cancer Cell Lines, 2012 Illinois Mathematics and Science Academy
The Expression Of Ecotropic Virus Integration Site-1 In Seven Cancer Cell Lines, Wendy Bindeman '12
Student Publications & Research
The ecotropic virus integration site-1 (EVI1) gene is a transcriptional repressor implicated in the control of cell proliferation and frequently over-expressed in cancerous cells. I investigated the expression of this gene across seven cancer cell lines of varying morphologies. The tested lines included leukemia lines Kasumi-3, U937, MOLT-4, and CEM, breast cancer line MCF7, colorectal cancer line HT-29, and glioblastoma line M059K. Kasumi-3 and HT-29 are documented to have high EVI1 expression. Protein concentrations were normalized with respect to actin using SDS-PAGE and Western blotting. Western blots for EVI1 showed expression of an unidentified protein with a molecular weight of …

The Effect Of Load On Movement Coordination During Sled Towing, 2012 University of New England
The Effect Of Load On Movement Coordination During Sled Towing, Michael Lawrence, Daniel Leib, Cara Masterson, Erin Hartigan
INTRODUCTION Towing sleds while walking is a popular resistance exercise for the healthy athlete. One reason for the popularity of sled towing is that it is widely believed to be a ‘functional’ exercise. Preliminary research suggests towing while walking can increases lower extremity moment impulses; however whether towing a sled utilizes the same coordination patterns as un-resisted walking is unknown. While altered patterns may not be as relevant to a healthy athlete, sled towing is also sometimes used in the rehabilitation of athletes who sustained a lower extremity injury (anterior cruciate ligament rupture) with the goal of regaining movement symmetry. …

Lipomas are common benign mesenchymal tumors. They can develop in virtually all organs throughout the body. Colonic lipomas are uncommon, benign, submucosal adipose tumors that are usually asymptomatic. Large lipomas can cause symptoms such as constipation, abdominal pain, rectal bleeding and intussusception. We report a case series of two colonic submucosal lipomas with different presentations, elaborating the importance of computerised tomography (CT) imaging in the diagnosis.
