Pathophysiology Of Migraine, Tina Capers

Nursing Student Class Projects (Formerly MSN)

Migraine is a primary headache disorder and is ranked 19th among all diseases world-wide that cause disability (International Headache Society, 2013). There are more than 37 million Americans who experience migraine. Migraine is most commonly experienced by individuals between the ages of 15 and 55 and 70% to 80% of migraineurs have a family history of migraine (National Headache Foundation, 2014). Migraine is the most common headache disorder for which patients obtain medical care (Minen, Tanev, & Friedman, 2014, p. 1131). Estimated migraine healthcare costs in the United States are $19.6 billion annually (Da Silva & Tepper, 2012, p. 824). …

Diagnosis, Pathophysiology, And Clinical Treatment Of A Patient With A Pheochromocytoma, Tricia L. Hale

Nursing Student Class Projects (Formerly MSN)

Hypertension is an extremely common diagnosis today. This condition can be caused by a multitude of factors, and can inversely cause numerous unfavorable processes in the body. One rare but significant source of hypertension is a tumor known as a pheochromocytoma, or PCC. This usually benign tumor is most often located on an adrenal gland, and can have a grave impact on the cardiovascular system. The tumor intermittently secretes an excess of the catecholamine norepinephrine, and if large enough, also secretes epinephrine [9]. These episodic bursts can cause extreme hypertension and tachycardia, leading to, at times fatal results. By understanding …

Craniocervical Arterial Dissection, Joseph Weisenberger

Nursing Student Class Projects (Formerly MSN)

The annual incidence for spontaneous carotid artery dissection (CAD) ranges from 2 to 3/100,000 patients and is even lower for a spontaneous vertebral artery dissection (VAD). Furthermore, there is only a .08% - .04% chance for the incidence of a traumatic dissection (TD), of the entire trauma population (Mortazvi, Verma, Tubbs, Harrigan, 2011). However, despite these low levels, CAD/VADs pose a serious threat to a patient’s plan of care if not identified and treated early.

The Effects Of Lipoxin A4 (Lxa4) On Neutrophil Biology In Sepsis, Benedict Wu

Graduate School of Biomedical Sciences Theses and Dissertations

During sepsis, neutrophils are inappropriately activated and have prolonged lifespans, thus becoming dysfunctional. Excessive neutrophil activation can lead to tissue injury while neutrophil dysfunction can lead to decreased free radical production and reduced phagocytosis, preventing the host from clearing preexisting infections. Lipoxin A4 (LXA4) is a specialized pro-resolution mediator which reduces neutrophil migration and expression of proinflammatory mediators. Intact neutrophil functions are critical for the host to efficiently clear invading pathogens. The effects of LXA4 on neutrophil function in sepsis have not been established. Using the cecal ligation and puncture (CLP) model of sepsis, LXA4 administered 1 h after sepsis …

An Analysis Of Abnormal Electrocardiograms In First And Second Year Medical School Students, Molly Anne Kalish

PCOM Biomedical Studies Student Scholarship

The high stress level placed upon medical school students, particularly during their first and second didactic years, may have a negative effect on their health. Although surveys and subjective questionnaires have been used to evaluate the effects medical school has upon a student’s cardiovascular health, there has been little clinical data obtained to confirm this notion. The aim of this longitudinal study was to demonstrate whether any abnormal cardiovascular parameters, specifically QTc wave interval, cardiac axis vector and blood pressure abnormalities, could be documented to occur in two different classes of medical students during their first two years. Such information …

Parasitism Of The Zweeloo Woman: Dicrocoeliasis Evidenced In A Roman Period Bog Mummy, Nicole Searcey, Karl Reinhard, Eduard Egarter-Vigl, Frank Maixner, Dario Piombino-Mascali, Albert R. Zink, Wijnand Van Der Sanden, Scott Gardner, Raffaella Bianucci

School of Natural Resources: Faculty Publications

We undertook the analysis of Zweeloo Woman, a bog mummy from the Netherlands, to assess her parasitic state. Evidence of infection came from two areas: (1) liver paraffin sections and (2) microfossils washed from an intestinal section. Although the liver had shrunken considerably, objects consistent with operculated trematode eggs were found. After evaluating the range of trematode species that produce eggs in liver tissue, we arrived at the diagnosis of Dicrocoelium dendriticum. Although only 0.1 ml of sediment was recovered from an intestinal section, eggs of Ascaris lumbricoides and Trichuris trichiura were also identified. No eggs of D. dendriticum were …

Candidatus Syngnamydia Venezia, A Novel Member Of The Phylum Chlamydiae From The Broad Nosed Pipefish, Syngnathustyphle Typhle, Alexander Fehr, Elisabeth Walther, Heike Schmidt-Posthaus, Lisbeth Nufer, Anthony B. Wilson, Miroslav Svercel, Denis Richter, Helmut Segner, Andreas Pospischil, Lloyd Vaughan

Publications and Research

Chlamydia are obligate intracellular bacteria and important pathogens of humans and animals. Chlamydia-related bacteria are also major fish pathogens, infecting epithelial cells of the gills and skin to cause the disease epitheliocystis. Given the wide distribution, ancient origins and spectacular diversity of bony fishes, this group offers a rich resource for the identification and isolation of novel Chlamydia. The broad-nosed pipefish (Syngnathus typhle) is a widely distributed and genetically diverse temperate fish species, susceptible to epitheliocystis across much of its range. We describe here a new bacterial species, Candidatus Syngnamydia venezia; epitheliocystis agent of S. typhle and close relative to …

Development Of Repressible Systems To Control Gene Expression In Vaccinia Virus, Allison Titong

Master's Theses

Two vaccinia virus (VACV) expression systems that contain elements from the lactose (lac) and the tetracycline (tet) operons of E. coli were developed to repress the expression of a reporter gene, enhanced green fluorescent protein (EGFP), in the presence of tet operon inducers. In the first system, lac and tet operon elements were arranged in a gene circuit, and in the presence of increasing concentrations of a lac operon inducer (isopropyl-β-D-thiogalactoside, IPTG), EGFP expression increased in a dose dependent manner and at high IPTG concentrations, expression reached the same levels as a positive control virus. Importantly, in the …

Development Of A Protocol To Measure Gene Expression In The Mouse Tibia, Daniel Hoover

Biomedical Engineering

Numerous molecular factors active in bone tissue direct fracture repair and remodeling which can be altered by disease conditions such as Peripheral Arterial Disease (PAD) and Osteoporosis. Methods of molecular biology are commonly applied to investigate the expression and role of these molecular factors. This project presents a robust three-step protocol for examining gene expression in the mouse tibia. The protocol begins with isolating RNA from a flash frozen tibia sample. The isolated RNA is reverse transcribed into cDNA. Finally, PCR is performed to indentify expressed genes. Establishing this protocol will allow further research into the mechanisms of bone remodeling …

Pulmonary Hyalinising Granuloma: A Rare Pulmonary Disorder, Arsalan Rahatullah, Zeeshan Waheed, Javaid A Khan, Nasir-Ud-Din

Section of Pulmonary & Critical Care

Pulmonary hyalinising granulomas are rare, noninfectious fibrosclerosing lesions of the lung which can mimic metastatic disease. It was first described in literature by Engleman et al in the year 1977. Its etiology is unknown but they may be caused by an exaggerated immune response. The patient typically presents with cough, chest pain. dyspnoea or haemoptysis in association with multiple bilateral parenchymal nodules. We report the case of a 20 years old male who presented with a 12-month history of worsening dry cough. His plain chest radiograph and subsequent CT scan revealed bilateral pulmonary nodules. A CT guided biopsy of the …

Heterotopic Ossification: Cellular Basis, Symptoms, And Treatment, Brian Wolfe

Senior Honors Theses

Heterotopic ossification (HO) is the process by which calcified bone develops in soft tissues. Because of the abnormal calcification, complications such as bone deformation, loss of range of motion, and joint immobility adversely affect patients. There are many genetic types of heterotopic ossification, namely fibrodysplasia ossificans progressiva, progressive osseous heteroplasia, and Albright hereditary osteodystrophy. However, this condition can also arise from surgery, burns, or traumatic injuries, so it is seen as an important area for research in the future. There are various treatments available such as non-steroidal anti-inflammatory drugs and radiation therapy, as well as combinations of the two. The …

Immune Recognition Of Self Nucleic Acids Driven By Endogenous Antimicrobial Peptides: Role In Autoimmunity, Dipyaman Ganguly

Dissertations and Theses (Open Access)

Innate immune recognition of extracellular host-derived self-DNA and self-RNA is prevented by endosomal seclusion of the Toll-like receptors (TLRs) in the dendritic cells (DCs). However, in psoriasis plasmacytoid dendritic cells have been found to be able to sense self-DNA molecules in complex with the endogenous cationic antimicrobial peptide LL37, which are internalized into the endosomal compartments and thus can access TLR9. We investigated whether this endogenous peptide can also interact with extracellular self-RNA and lead to DC activation. We found that LL37 binds self-RNA as well as self-DNA going into an electrostatic interaction; forms micro-aggregates of nano-scale particles protected from …
