Life Drawing With Gross Anatomy Medical Students And Implications For Art Therapy, Elliott Addesso

EVMS School of Health Professions Theses & Dissertations

It is important to incorporate humanities training into medical education in order to enhance the potential for humane and ethical interactions among physicians. In this study, a life drawing studio course was led by an art therapy graduate student to explore the effects of a life drawing course on medical students concurrently enrolled in Gross Anatomy. Based on students’ perceptions of their experience in the life drawing class, theoretical implications for the practice of art therapy in studio applications were discussed.

Five medical students participated in the course on a voluntary, non-credit basis. The course consisted of seven meetings and …

Multisensory Input To The Lateral Rostral Suprasylvian Sulcus (Lrss) In Ferret, Elizabeth Hagood

Theses and Dissertations

For the brain to construct a comprehensive percept of the sensory world, information from the different senses must converge onto individual neurons within the central nervous system. As a consequence, how these neurons convert convergent sensory input into multisensory information is an important question facing neuroscience today. Recent physiological studies have demonstrated the presence of a robust population of multisensory neurons in the lateral bank of the rostral suprasylvian sulcus (LRSS) in adult ferret (Keniston et al, 2008). The LRSS is a region situated between somatosensory and auditory cortices, where bimodal (somatosensory-auditory) neurons occupy the greatest percentage of the sensory-responsive …

Universal Screening For Extracardiac Abnormalities In Neonates With Congenital Heart Disease., Javier H. Gonzalez, Girish S. Shirali, Andrew M. Atz, Sarah N. Taylor, Geoffrey A. Forbus, Sinai C. Zyblewski, Anthony M. Hlavacek

Manuscripts, Articles, Book Chapters and Other Papers

Extracardiac or genetic abnormalities (EGA) represent a factor in the morbidity of patients with congenital heart disease. We evaluated the way neonates with CHD are screened at our institution and determined the yield for the screening tests. We reviewed the charts of 223 neonates with structural CHD. Subjects were categorized into 6 groups: univentricular, left-sided obstructive lesions, right-sided obstructive lesions, septal defects, conotruncal defects (CTD), and other. We reviewed which patients underwent cranial ultrasonogram (CUS), abdominal ultrasonogram (AUS), and/or genetic studies (GS) as well as their results. There was a high prevalence of EGA in each group by CUS (32% …

Smoking Enhances Risk For New External Genital Warts In Men, Dorothy J. Wiley, David Elashoff, Emmanuel V. Masongsong, Diane M. Harper

Dartmouth Scholarship

Repeat episodes of HPV-related external genital warts reflect recurring or new infections. No study before has been sufficiently powered to delineate how tobacco use, prior history of EGWs and HIV infection affect the risk for new EGWs. Behavioral, laboratory and examination data for 2,835 Multicenter AIDS Cohort Study participants examined at 21,519 semi-annual visits were evaluated. Fourteen percent (391/2835) of men reported or were diagnosed with EGWs at 3% (675/21,519) of study visits. Multivariate analyses showed smoking, prior episodes of EGWs, HIV infection and CD4+ T-lymphocyte count among the infected, each differentially influenced the risk for new EGWs.

Paracrine Sonic Hedgehog Signalling By Prostate Cancer Cells Induces Osteoblast Differentiation, Samantha M Zunich, Taneka Douglas, Maria Valdovinos, Tiffany Chang

Dartmouth Scholarship

Sonic hedgehog (Shh) and components of its signalling pathway have been identified in human prostate carcinoma and increased levels of their expression appear to correlate with disease progression and metastasis. The mechanism through which Shh signalling could promote metastasis in bone, the most common site for prostate carcinoma metastasis, has not yet been investigated. The present study determined the effect of Shh signalling between prostate cancer cells and pre-osteoblasts on osteoblast differentiation, a requisite process for new bone formation that characterizes prostate carcinoma metastasis.

Assessment Of Asthma Control Using The Asthma Control Test At A Tertiary Care Centre In Karachi, Pakistan, Sana Shoukat, Saqib Ali Gowani, Ameer Ali Khowaja, Javaid Khan

Section of Pulmonary & Critical Care

The aim of our study was to assess asthma control among asthmatics at a tertiary care setting in Karachi using ACT questionnaire. The ACT questionnaire was filled by known asthmatics in January 2007. A total of 150 questionnaires were filled of which, 61 (40%) were males and 89 (60%) females. Mean ACT score was 17.71 +/- 4.41. Association between sex and asthma control was not statistically significant. Significant association was seen with asthma control and Ipratropium bromide inhaler. Asthma control among patients at a tertiary care centre is moderate. ACT can be used to follow patients in the hospital.

Microscopic Analysis Of Sympathetic And Parasympathetic Distribution, Terminal Morphology, And Interaction In Whole-Mount Atria, Scott Harden

Electronic Theses and Dissertations

The sympathetic (SNS) and parasympathetic (PSNS) branches of the autonomic nervous system (ANS) innervate the heart, exerting excitatory and inhibitory influences (respectively) over cardiac functions (heart rate, AV conduction velocity, and contractility). However, the distribution and structure of SNS and PSNS innervation has not yet been well studied. Detailed characterization of the distributional organization and structural morphology of the SNS and PSNS in normal states is essential to the study of pathological autonomic remodeling. The present study utilized double immunohistochemical labeling techniques to examine tyrosine hydroxylase (TH) immunoreactive (IR) SNS and vesicular acetylcholine transporter (VAChT) IR PSNS axons and terminal …

Loss Of Ski Expression In Testicular Cancer Leads To An Enhanced Invasive Phenotype Through Both Bmp-Dependent And Bmp-Independent Pathways, Amy N. Nash

Theses, Dissertations and Capstones

The proto-oncogene SKI is a transcription factor and a co-repressor of the TGFβ superfamily, including TGF

β and BMP. However, additional data suggests that SKI may function as a tumor suppressor in some cell types. The TGFβ superfamily has been implicated in cancer progression and germ cell migration. Testicular cancer afflicts men during their peak reproductive years and is the most common cancer among men of this age group. Cisplatin-based chemotherapy is the standard treatment for testicular cancer. This treatment can lead to undesirable side effects, including infertility. We have shown that SKI expression is decreased in testicular germ cell …

Enumeration Of Endothelial Progenitor Cells In Hind Limb Suspended Rats And The Mechanics Of Endothelial Wound Healing, Jarrod Matthew Pennington

Theses, Dissertations and Capstones

The endothelium repairs itself through two methods. One is by the activity of circulating endothelial progenitor cells (EPCs). EPCs are immature endothelial cells that circulate the bloodstream that are capable of proliferation and differentiation into mature endothelium. It is thought that EPCs contribute to the repair and replacement of damaged endothelial cells in the process of reendothelialization. Physical inactivity and bed rest are known to be deleterious to the endothelium. It is possible that this inactivity is also deleterious to the number of viable EPCs, which would reduce the ability of the endothelium to repair itself. We used hind limb …

Impairments In Attention In Occasionally Snoring Children: An Event-Related Potential Study, Maria E. Barnes, Elizabeth A. Huss, Krista N. Garrod, Eric Van Raay, Ehab Dayyat, Dennis L. Molfese

Center for Brain, Biology, and Behavior: Faculty Publications

Objective—To determine whether minimal snoring is benign in children.

Procedure—22 rarely snoring children (mean age=6.9 years, 11 females) and age- and sexmatched controls participated in an auditory oddball task wearing 128-electrode nets. Parents completed Conner’s Parent Rating Scales-Revised Long (CPRS-R:L).

Results—Snorers scored significantly higher on 4 CPRS-R:L subscales. Stepwise regression indicated that two ERP variables from a region of the ERP that peaked at 844 ms post-stimulus onset predicted CPRS-R:L ADHD Index scores.

Conclusions—Occasional snorers according to parental report do exhibit ADHD-like behaviors. Basic sensory processing is longer than in controls, suggesting that delayed frontal activation requires more effort in …

Lymphomatoid Granulomatosis Masquerading As Interstitial Pneumonia In A 66-Year-Old Man: A Case Report And Review Of Literature, Ashima Makol, Kalyan Kosuri, Deimante Tamkus, Wanderley De M Calaca, Howard T. Chang

Wayne State University Associated BioMed Central Scholarship

Abstract

Lymphomatoid granulomatosis (LG) is a rare, Epstein-Barr virus (EBV)-associated systemic angiodestructive lymphoproliferative disorder that may progress to a diffuse large B cell lymphoma. Pulmonary involvement may mimic other more common lung pathologies including pneumonias. Therapeutic standards have not been established for LG, but rituximab, interferon-α2b (INF-α2b), and chemotherapy have shown to improve symptoms and long term prognosis.

We report a case of rapid respiratory deterioration in a 66-year-old man with clinical presentation, chest radiography, pulmonary function testing and high resolution computed tomography (HRCT) findings consistent with idiopathic interstitial pneumonia, but very poor response to antibiotics and low dose steroids. …

Human Cytomegalovirus Us28: A Functionally Selective Chemokine Binding Receptor, Jennifer Totonchy, Jay A. Nelson, Daniel N. Streblow

Pharmacy Faculty Articles and Research

The Human Cytomegalovirus (HCMV)-encoded chemokine receptor US28 is the most well-characterized of the four chemokine receptor-like molecules found in the HCMV genome. US28 been studied as an important virulence factor for HCMV-mediated vascular disease and, more recently, in models of HCMV-associated malignancy. US28 is a rare multi-chemokine family binding receptor with the ability to bind ligands from two distinct chemokine classes. Ligand binding to US28 activates cell-type and ligand-specific signaling pathways leading to cellular migration, an example receptor functional selectivity. Additionally, US28 has been demonstrated to constitutively activate PLC and NFkB. Understanding the structure/function relationships between US28, its ligands and …

Journal Articles: Pulmonary & Critical Care Med

There is considerable variability in the susceptibility of smokers to develop chronic obstructive pulmonary disease (COPD). The only known genetic risk factor is severe deficiency of alpha(1)-antitrypsin, which is present in 1-2% of individuals with COPD. We conducted a genome-wide association study (GWAS) in a homogenous case-control cohort from Bergen, Norway (823 COPD cases and 810 smoking controls) and evaluated the top 100 single nucleotide polymorphisms (SNPs) in the family-based International COPD Genetics Network (ICGN; 1891 Caucasian individuals from 606 pedigrees) study. The polymorphisms that showed replication were further evaluated in 389 subjects from the US National Emphysema Treatment Trial …

Primary Cilia: Highly Sophisticated Biological Sensors, Wissam A. Aboualaiwi, Shao T. Lo, Surya M. Nauli

Pharmacy Faculty Articles and Research

Primary cilia, thin hair-like structures protruding from the apical surface of most mammalian cells, have gained the attention of many researchers over the past decade. Primary cilia are microtubule-filled sensory organelles that are enclosed within the ciliary membrane. They originate at the cell surface from the mother centriole that becomes the mature basal body. In this review, we will discuss recent literatures on the roles of cilia as sophisticated sensory organelles. With particular emphasis on vascular endothelia and renal epithelia, the mechanosensory role of cilia in sensing fluid shear stress will be discussed. Also highlighted is the ciliary involvement in …

Rat Cytomegalovirus Infection Depletes Mhc Ii In Bone Marrow Derived Dendritic Cells, Carmen C. Baca Jones, Craig N. Kreklywich, Ilhem Messaoudi, Jennifer Totonchy, Erin Mccartney, Susan L. Orloff, Jay A. Nelson, Daniel N. Streblow

Pharmacy Faculty Articles and Research

While cytomegalovirus (CMV) infects and replicates in a multitude of cell types, the ability of the virus to replicate in antigen presenting cells (APCs) is believed to play a critical role in the viral dissemination and latency. CMV infection of APCs and manipulation of their function is an important area of investigation. CMV down regulation of MHC II is reportedly mediated by the HCMV proteins US2, US3, UL83, UL111a (vIL10) or through the induction of cellular IL10. In this study, we demonstrate that rat CMV (RCMV) significantly reduces MHC II expression by mechanisms that do not involve orthologues of the …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

A resistance training program, where the exercise was uninterrupted (UT, i.e. continuous repetitions) was compared against another resistance training program where the exercise was interrupted (IT, i.e. 2 exercise sessions during a training day) for enhancing bone modeling and bone mineral density (BMD) in maturating animals. The total volume of work performed between the two resistance training programs was equivalent by design. Young male rats (similar to 8 weeks old) were randomly divided into Control (Con, n = 8), UT (n = 8) and IT (n = 7) resistance trained groups. The UT and IT groups were conditioned to climb …

Differential Ligand Binding To A Human Cytomegalovirus Chemokine Receptor Determines Cell Type-Specific Motility, Jennifer Totonchy, Ryan Melnychuk, Patricia P. Smith, Joshua Powell, Laurel Hall, Victor R. Defilippis, Klaus Fruh, Martine Smit, David D. Schlaepfer, Jay A. Nelson, Daniel N. Streblow

Pharmacy Faculty Articles and Research

While most chemokine receptors fail to cross the chemokine class boundary with respect to the ligands that they bind, the human cytomegalovirus (HCMV)-encoded chemokine receptor US28 binds multiple CC-chemokines and the CX3Cchemokine Fractalkine. US28 binding to CC-chemokines is both necessary and sufficient to induce vascular smooth muscle cell (SMC) migration in response to HCMV infection. However, the function of Fractalkine binding to US28 is unknown. In this report, we demonstrate that Fractalkine binding to US28 not only induces migration of macrophages but also acts to inhibit RANTES-mediated SMC migration. Similarly, RANTES inhibits Fractalkine-mediated US28 migration in macrophages. While US28 binding …

Pharmacy Faculty Articles and Research

A specific and sensitive liquid chromatography (LC)-tandem mass spectrometric method for quantitative determination of methylprednisolone (MP) in rat plasma and liver was developed and validated using triamcinolone acetonide as an internal standard. Liquid-liquid extraction using tert-butyl methyl ether was used to extract the drug and the internal standard from plasma and liver. The separation of MP was performed on a C(18) column with a mobile phase of acetonitrile:0.5% formic acid aqueous solution (85:15, v/v) over 4 min. The assay was based on the selected reaction monitoring transitions at m/z 375 -> 161 for MP in plasma, 375 -> 357 for …

Control Of Myosin Motor Activity And Actin Filament Translation By Alteration Of Assay Reducing Potential, Siva Krishna Nalabotu

Theses, Dissertations and Capstones

The use of biomolecular motors for nanotechnological applications has been impaired by an inability to control biomolecular motor activity in a temporal fashion. Previous data has suggested that myosin activity can be modulated by inducing changes in the degree of myosin oxidation. The hypothesis of this study is that myosin motor activity can be regulated by altering the amount of antioxidants and reducing agents present in assay solution. To test this hypothesis we systematically altered the concentration of reducing agents and examined the effects of these changes on myosin-dependent actin filament translation. Our findings indicate that myosin activity can be …

The Presynaptic Regulation Of Isolated Neonatal Rat Carotid Body Type I Cells By Histamine, Drew C. Burlon

Browse all Theses and Dissertations

It has been previously shown that Carotid Body Type I cells have the ability to synthesize, package and release histamine in response to hypoxia, thereby contributing to the modulation of respiration within the rat. Here, isolated neonatal rat carotid body type I cells were used to identify the presynaptic effects of histamine and the specific receptor subtypes that modulate them. Although all four histamine receptor subtypes are expressed on the type I cells, and preliminary data showed promising results, further data proved that the activation of these receptors with histamine or selective agonists caused no rise in intracellular calcium ([Ca2+]i) …

Reorganization Of Ia Afferent Synapses On Motoneurons After Peripheral Nerve Injuries, Haley E. Titus

Browse all Theses and Dissertations

After peripheral nerve injuries patients lose and do not recover the stretch reflex which leads to altered locomotor function. The focus of this thesis is to investigate the structural integrity of the central connection between Ia afferents and alpha motoneurons that mediate the stretch reflex. The overall hypothesis is that the density and distribution of Ia synapses on motoneurons is altered after peripheral nerve injuries. Analysis of Ia afferent-motoneuron contacts, revealed by vesicular glutamate transporter 1 (VGLUT1) immunoreactivity, on the soma and dendritic arbor of motoneurons after peripheral nerve injuries revealed major reorganizations in the distribution and density of Ia …

Inhibition Of Pro-Inflammatory Processes Reduces Sensitization Of The Behavioral Response To Maternal Separation, Kristopher Doojin Paik

Browse all Theses and Dissertations

The current study examined the behavioral sensitization of guinea pig pups in response to consecutive days of maternal separation. In the first experiment, guinea pigs that received centrally administered artificial cerebrospinal fluid or IL-10 exhibited sensitization of passive behaviors from Day 1 to Day 2. IL-10 decreased the levels of passive behaviors on Day 1, as well as the increase on Day 2. The second experiment used unoperated pups, which also showed sensitization of the passive response from Day 1 to Day 2, though the effect appeared reduced relative to control pups of Experiment 1. Collectively, this investigation confirms previous …

Role Of Cyclophilin D In Secondary Spinal Cord And Brain Injury, Jordan Mills Clark

University of Kentucky Doctoral Dissertations

In the hours and days following acute CNS injury, a secondary wave of events is initiated that exacerbate spinal tissue damage and neuronal cell death. A potential mechanism driving these secondary events is opening of the mitochondrial permeability transition pore (mPTP) and subsequent release of several cell death proteins. Previous studies have shown that inhibition of cyclophilin D(CypD), the key regulating component in mPTP opening, was protective against insults that induce necrotic cell death. We therefore hypothesized that CypD-null mice would show improved functional and pathological outcomes following spinal cord injury (SCI) and traumatic brain injury (TBI). Moderate and severe …
