Using Vesicular Stomatitis Virus Glycoprotein To Pseudotype Bacmam Viruses For Enhancement Of Transduction Efficiency, Lydia Sanchez

PCOM Biomedical Studies Student Scholarship

Baculovirus has been a common tool for protein production since the mid 1980s. The virus has an exclusive tropism only capable of infecting the larval stages of insects. Originally, baculovirus recombinant gene expression used Spodoptera frugiperda (Sf9) insect cells as the host cells for protein production. However, in 1995, it was discovered that baculoviruses could be modified to transduce mammalian cells with the insertion of a mammalian promoter and gene of interest. Due to its ease of generation and low biology safety hazards, this technology, known as BacMam (Baculovirus Mammalian) is popular in the research field for protein production and …

Crosstalk Between Wnt And Rho Pathways In Ameloblast-Lineage Cells, Kate Shusterman

PCOM Biomedical Studies Student Scholarship

Exposure to high levels of fluoride during tooth development will lead to mineralization defects and a decrease in enamel strength, known as enamel fluorosis. It has been proposed that fluoride may alter the cytoskeleton of ameloblasts, cells that secrete enamel during tooth development. This change is carried out through the Rho pathway, more specifically through RhoA. RhoA is stimulated by Wnt3a, a part of the Wnt pathway involved in regulation of cell proliferation and differentiation. The main component of the Wnt pathway, β-catenin, is expressed in dental epithelium and acts by linking cadherins to the actin cytoskeleton in cell adhesion. …

The Role Of Protein Kinase C Epsilon In Hydrogen Peroxide And Nitric Oxide Release During Oxidative Stress Caused By Extracorporeal Shockwave Lithotripsy, Edward S. Iames

PCOM Biomedical Studies Student Scholarship

Clinical extracorporeal shock wave lithotripsy (ESWL) treatment to ablate kidney stones can cause acute damage to the renal microvasculature. Accumulation of continued treatment with shockwave therapy can lead to chronic damage to the kidney, and lead to clinical hypertension. Shockwaves have been shown to stimulate endothelial cells to release superoxide (SO), which is converted to hydrogen peroxide (H₂O₂), and reacts with nitric oxide (NO) to produce peroxynitrite anion (OONO^-), creating a powerful oxidant that increases oxidative stress while simultaneously reducing NO bioavailability. Increased oxidative stress during events such as ESWL, also uncouples NO production …

Effect Of Prior Anterior Superior Iliac Spine Compression Testing On Second Assessor Findings: Implications For Inter-Examiner Reliability Testing, Frank Casella Ms, Michael L. Kuchera Do, Faao, Jeffrey A. Nelson, Veronica Ferencz Mba, Nicole E. Myers

Research Day

BACKGROUND: Osteopathic physicians use palpation to diagnose sacroiliac joint somatic dysfunction (SD) -- including the Anterior Superior Iliac Spine (ASIS) Compression Test for dysfunctional side lateralization. (Literature suggests right-sided lateralization in 80% of asymptomatic individuals). Accurate, reliable tests are crucial however to diagnose SD and kappa (κ) analysis is a gold-standard to determine the degree of interexaminer reliability for tests. Few studies have examined the effect the palpatory examination has on subsequent diagnostic findings and therefore on κ-values.

Inter-Examiner Reliability Of An Anterior Superior Iliac Spine Compression Test Used To Lateralize Pelvic Somatic Dysfunction To The Right Side Or Not, Frank Casella Ms, Michael L. Kuchera Do, Faao, Nicole E. Myers, Jeffrey A. Nelson, Veronica Ferencz Mba

Research Day

BACKGROUND: Osteopathic physicians use a number of palpatory structural examinations to diagnose pelvic somatic dysfunction (SD). They may elect to use the Anterior Superior Iliac Spine (ASIS) Compression Test to lateralize the dysfunctional side. Accurate, reliable tests are crucial to neuromusculoskeletal diagnosis and this study employs the kappa (κ) analysis protocol recommended for assessing interexaminer reliability of manual medicine tests (published by the Fédération Internationale de Médecine Manuelle [FIMM]). κ-values ≥0.40 (moderate agreement) are considered to be acceptable for use in the clinical setting.

The Use Of Objective Data To Improve Interexaminer Reliability, Veronica Ferencz Mba, Frank Casella Ms, Jeffrey A. Nelson, Nicole E. Myers, Michael L. Kuchera Do, Faao

Research Day

BACKGROUND: In Osteopathic Manipulative Medicine (OMM) and Manual/Musculoskeletal Medicine (MMM), palpatory diagnosis is performed on a regular basis to diagnose somatic dysfunction (SD). This examination requires careful and precise touch coupled with subjective interpretation by individual examiners who may have been trained to evaluate SD through different methods. Interexaminer reliability studies aim to minimize variance by providing quantifiable scientific data to evaluate specific test protocols which can then be taught to practitioners. In a previous PCOM study, two examiners independently diagnosed innominate bone dysfunction lateralized using the ASIS compression test on a large group of subjects. A pressure monitoring system …

Comparing Inter-Examiner Reliability Levels When Diagnosing Male & Female Innominate Dysfunctions Using A Hemi-Pelvise Compression Lateralization Test And Pelvic Landmark Levels., Nicole E. Myers, Michael L. Kuchera Do, Faao, Veronica Ferencz Mba, Jeffrey A. Nelson, Frank Casella Ms

Research Day

BACKGROUND: When diagnosing innominate somatic dysfunctions it may be relevant to recognize that structural, functional, and hormonal differences exist between male and female pelvises. The female pelvis is less massive, ilia are less sloped, and female hormones influence ligamentous tension. Despite these differences, few studies have analyzed gender effects on inter-examiner reliability when using palpatory diagnosis to diagnose innominate dysfunctions. In this study, we hypothesized that interexaminer reliability would be higher in male subjects than in female subjects due cyclic variability of hormonal influence of ligamentous tension in the female pelvis. The kappa (κ) statistic was selected to evaluate …

Infection Of Neuronal Cells By Chlamydia Pneumoniae And Herpes Simplex Virus Type 1 Alters Expression Of Genes Associated With Alzheimer’S Disease, Morgan M. Devins, Fiora D. Zoga, Brian J. Balin, Denah M. Appelt, Susan T. Hingley

Scholarly Posters

Several studies have suggested an infectious etiology for Alzheimer’s disease (AD). We have been investigating a potential role for both Chlamydia pneumoniae and Herpes simplex virus type 1 (HSV1) in the initiation of sporadic late-onset AD. Our current study focuses on investigation of gene expression using Alzheimer-specific Real-Time PCR microarrays on RNA derived from SKNMC human neuronal cells infected with C. pneumoniae and/or HSV1. There are distinct differences in the patterns of gene regulation by the two pathogens. For example, C. pneumoniae induces expression of genes involved in amyloid production and processing, such as β-amyloid precursor protein (APP), β-site APP-cleaving …

Analysis Of Chlamydia Pneumoniae-Infected Monocytes Following Incubation With A Novel Peptide, Acaly18, Implicates The Inflammasome In Clearance Of Infection, Brian J. Balin, James D. Thacker, Charles Lim, Corey M. Caruthers, Susan T. Hingley, Juliana Zoga, Denah M. Appelt

Scholarly Posters

Chlamydia pneumoniae infection may be a trigger for the pathology observed in sporadic lateonset Alzheimer’s disease as a function of initiating neuroinflammation following entry of the organism into the brain. We have hypothesized that one entry mechanism may be by bloodborne infected monocytes trafficking the infection into the brain. This study focuses on infection of monocytes in vitro followed by analysis using immunofluorescence labeling and RT-PCR-microarray techniques. The microarrays utilized consisted of an Alzheimer’s disease pathway array and an innate and adaptive immunity array from SAbiosciences. Analysis by real time PCR for both gene arrays was performed on uninfected and …

Androgen Receptor-Dependent Effects Of Resveratrol On Tnsin Mrna Levels In Prostate Cancer Cells, Courtney Pisano

PCOM Biomedical Studies Student Scholarship

The chemopreventive effects of resveratrol (RSV) on cancers, including prostate cancer, have been well documented; but the mechanisms are not well known. It has been reported recently that tensin, a matrix-adhesion protein, which is greatly down-regulated in prostate cancer, has been induced by RSV in several cancer cell lines. In order to know if RSV up-regulates tensin in prostate cells, we first treated LNCaP cells with RSV and demonstrated that tensin mRNA levels were upregulated by RSV in a time and dose dependent manner. Since LNCaP cells are androgen receptor (AR) positive and previous findings have shown that RSV down-regulates …

The Role Of Endothelial Nitric Oxide Synthase (Enos) Uncoupling On Leukocyte-Endothelial Interactions In Rat Mesenteric Postcapillary Venules, Maria Kern

PCOM Biomedical Studies Student Scholarship

Endothelial derived nitric oxide (NO) is essential in the regulation of blood pressure and attenuates leukocyte-endothelial interactions associated with vascular injury. However, when endothelial-derived NO is decreased, endothelial dysfunction results and promotes inflammation characterized by increased leukocyte-endothelial interactions. Under normal conditions, eNOS produces NO in the presence of an essential cofactor, tetrahydrobiopetrin (BH4) by facilitating the reduction of molecular oxygen to L-arginine oxidation and generation of L-citrulline. Whereas uncoupled eNOS refers to the electron transfer that becomes uncoupled to L-arginine oxidation and therefore superoxide (SO) is generated when the dihydrobiopetrin (BH2) to BH4 ratio is increased. SO is subsequently converted …

Carbon Monoxide And Nitric Oxide Induced-Heme-Based Modification Of Alpha-2-Antiplasmin And Plasmin Activity, Matthew R. Arkebauer

PCOM Biomedical Studies Student Scholarship

Objectives: Carbon monoxide (CO) derived from cigarette smoke or released from carbon monoxide releasing-molecule 2 (CORM-2), diminishes fibrinolysis. The primary purpose of this study was to determine if CO diminished fibrinolysis by means of enhancing α2-antiplasmin via an alleged heme group. Methods: Plasma, isolated α2-antiplasmin and isolated plasmin were exposed to CO released from CORM-2 (tricarbonyldichlororuthenium (II) dimer) and nitric oxide (NO) via a NO donor to induce carboxyheme and metheme states. Exposed, isolated enzymes were placed in either α2-antiplasmin deficient or normal plasma. Effects of CO and NO on tissue-type plasminogen activator initiated fibrinolysis were determined by thrombelastography. Liquid …

Infection With Chlamydia Pneumoniae In Neuronal Cells Alters The Expression Of Genes Involved In Apoptosis And Autophagy Pathways, Annette K. Slutter

PCOM Biomedical Studies Student Scholarship

Dysfunctions in cellular mechanisms such as apoptosis and autophagy have been implicated in the neurodegeneration associated with Alzheimer’s disease (AD). Autophagy in AD pathogenesis has been linked to the endosomal-lysosomal system, which has been shown to play a role in amyloid processing. Studies have suggested that apoptosis may contribute to the neuronal cell loss observed in AD; however, there is no evidence of the apoptotic process leading to terminal completion. Aβ1-42 has been shown to induce apoptosis in neurons and may be an initiating factor in AD. Our previous studies demonstrated that neurons infected with C. pneumoniae are resistant to …

The Effects Of Protein Kinase C Inhibitors On Blood Nitric Oxide And Hydrogen Peroxide Release In Ischemia And Reperfusion Injury, Kyle D. Bartol

PCOM Biomedical Studies Student Scholarship

Vascular endothelial dysfunction is a key component initiating oxidative stress in ischemia/reperfusion (I/R). Endothelial dysfunction is characterized by an increase in hydrogen peroxide (H2O2) and a decrease in the bioavailability of nitric oxide (NO). Previous studies using protein kinase C (PKC) inhibitor Gö 6983 or PKC Beta (β) II inhibitor improved cardiac function in myocardial I/R, decreased leukocyte-endothelial interactions and leukocyte superoxide (SO) release and increased endothelial-derived NO release in vitro. This study examined the effects of Gö 6983 or PKC β II inhibitor on realtime H2O2 and NO release in femoral vein I/R in vivo. NO or H2O2 microsensors …

Small Intestine Submucosa Effects On Long Term Viability Of Transplanted Pancreatic Cells, Joshua P. Pregnar

PCOM Biomedical Studies Student Scholarship

The biologic functions carried out by the pancreas are, without a doubt, essential to life. This can be demonstrated by the fact that some diabetics require insulin supplementation and those suffering from other diseases of the pancreas, such as pancreatitis, or who have undergone pancreatectomy require supplementation with exocrine enzymes. As would be expected, we are constantly searching for more longterm, patient oriented solutions to chronic health conditions. As such, there has been a gradual transition from daily insulin injections to insulin pumps which allow for easier and more closely controlled glucose levels. Work has also been done regarding various …

Alzheimer's Disease Association With Chlamydia Pneumoniae, Andrew Short

PCOM Biomedical Studies Student Scholarship

Exogenous bacteria, such as Chlamydia pneumoniae, may be a cause of inflammation that contributes to the progression of Alzheimer's disease (AD). Inflammation has been previously established as a contributor to AD progression. Balin et al. first reported C. pneumoniae in the brains of post-mortem late onset AD patients. PCR analysis showed that 17/19 AD patients were positive for the organism in areas of the brain with typical AD-related neuropathology while 18/19 control patients were PCR-negative. Gerard et al. determined, using real-time PCR, that C. pneumoniae-infected cells colocalize with both neuritic senile plaques and neurofibrillary tangles, the defining pathologies of AD. …
