Novel Implications Of The Kallikrein-Kinin System In Diabetic Vasculopathy: A Proposed Role Of Prekallikrein In The Causation And Development Of Vascular Pathology In Diabetics, Rany Abdallah

MUSC Theses and Dissertations

Despite the clear association between diabetes and atherosclerotic vascular disease, the factors and mechanisms underlying the association between the two diseases are not well understood. Our preliminary studies, based on data obtained from the national Diabetes Control and Complication Trial/Epidemiology of Diabetes and Complications (DCCT/EDIC) cohort of type 1 diabetes subjects, suggest that diabetic atherosclerosis is linked to defects in the Kallikrein-Kinin System (KKS). Our research also found that apoliporotein E (ApoE) knockout mice, which have marked increase in total plasma cholesterol levels and a higher number of atherosclerotic lesions compared to wild type mice, have markedly higher plasma prekallikrein …

Characterization Of Calpain 10 Activity, Expression, And Inhibition, Christopher Joseph Giguere

MUSC Theses and Dissertations

Calpains are a family of Ca^2+-activated, non-lysosomal, cysteine proteases that have been implicated in a variety of physiological and pathological processes. Currently, the family consists of 14 members, of which eight are typical (calpains 1, 2, 3, 8, 9, 11, 12, and 14) and six are atypical (calpains 5, 6, 7, 10, 13, 15), based on the presence or absence of the Ca^2+-binding domain (domain IV), respectively. The atypical calpain have recently gained attention due to studies that have linked human diseases to mutations in specific calpain genes (Type 2 diabetes linked to calpain 10 and Limb Girdle Muscular Dystrophy …

An Assessment Of Noninvasive Measurements Of Arterial Compliance, Andrea D. Boan

MUSC Theses and Dissertations

Arterial stiffness is considered both a risk factor and indicator of cardiovascular disease. The purpose of this study was to examine the associations of cardiovascular risk indicators of arterial compliance among 226 black and white individuals enrolled in an outpatient clinical setting. Data were collected by survey and examination with a computerized arterial pulse waveform analyzer. Arterial stiffness was estimated by indirect estimates of small artery and large artery compliance, as well as pulse pressure. After adjustments for age, race, and gender, logistic regression identified hypertension, end organ damage, and overweight as the strongest predictors for the three arterial stiffness …

Pdgf-Driven Proliferation, Migration, And Il8 Chemokine Secretion In Human Corneal Fibroblasts Involve Jak2-Stat3 Signaling Pathway, Neeraj Vij, Ajay Sharma, Mahesh Thakkar, Sunilima Sinha, Rajiv R. Mohan

Pharmacy Faculty Articles and Research

Purpose: Platelet-derived growth factor (PDGF) is associated with corneal fibroblast migration and proliferation and plays an important role in corneal wound healing. However, the intracellular mechanisms of PDGF-mediated functions in corneal fibroblasts are poorly understood. We tested the hypothesis that PDGF functional activities in the cornea involve the Janus kinase-2/signal transducers and activators of transcription-3 (JAK2-STAT3) signaling pathway and whether PDGF induces the expression of suppressors of cytokine signaling 3 (SOCS3), belonging to the novel family of feedback regulators of cytokine and growth factor activities.

Methods: Human corneal fibroblast (HSF) cultures were used as an in vitro model for functional …

A Versatile Assay For The Identification Of Rna Silencing Suppressors Based On Complementation Of Viral Movement, Jason G. Powers, Tim L. Sit, Feng Qu, T. Jack Morris, Kook-Hyung Kim, Steven A. Lommel

Nebraska Center for Virology: Faculty Publications

The cell-to-cell movement of Turnip crinkle virus (TCV) in Nicotiana benthamiana requires the presence of its coat protein (CP), a known suppressor of RNA silencing. RNA transcripts of a TCV construct containing a reporter gene (green fluorescent protein) (TCV-sGFP) in place of the CP open reading frame generated foci of three to five cells. TCV CP delivered in trans by Agrobacterium tumefaciens infiltration potentiated movement of TCV-sGFP and increased foci diameter, on average, by a factor of four. Deletion of the TCV movement proteins in TCV-sGFP (construct TCVΔ92-sGFP) abolished the movement complementation ability of TCV CP. Other known suppressors of …

Devices In Heart Failure: Potential Methods For Device-Based Monitoring Of Congestive Heart Failure, Shahzeb M Munir, Roberta C Bogaev, Ed Sobash, K J Shankar, Sreedevi Gondi, Igor V Stupin, Jillian Robertson, M Alan Brewer, S Ward Casscells, Reynolds M Delgado, Amany Ahmed

Faculty, Staff and Student Publications

Congestive heart failure has long been one of the most serious medical conditions in the United States; in fact, in the United States alone, heart failure accounts for 6.5 million days of hospitalization each year. One important goal of heart-failure therapy is to inhibit the progression of congestive heart failure through pharmacologic and device-based therapies. Therefore, there have been efforts to develop device-based therapies aimed at improving cardiac reserve and optimizing pump function to meet metabolic requirements. The course of congestive heart failure is often worsened by other conditions, including new-onset arrhythmias, ischemia and infarction, valvulopathy, decompensation, end-organ damage, and …

Foreign Accent Syndrome Mimicked By Garcin Syndrome With Spontaneous Resolution, Michael Hoffmann

Neurology Faculty Publications

An English speaking women developed a French accent, without any aphasic syndromes, in conjunction with multiple left sided cranial nerve deficits, temporally related to cranial trauma. Extensive testing with multimodality magnetic resonance imaging, cerebrospinal fluid and laboratory analysis was unremarkable. She was followed over a 3 year period during which her French accent resolved as did the majority of her multiple unilateral cranial neuropathies. The neurological diagnoses included a foreign accent syndrome attributed to a reversible Garcin syndrome.

Analytical Approaches To Detect Maternal/Fetal Genotype Incompatibilities That Increase Risk Of Pre-Eclampsia, Neeta Parimi, Gerard Tromp, Helena Kuivaniemi, Jyh Nien, Ricardo Gomez, Roberto Romero, Katrina Ab Goddard

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

In utero interactions between incompatible maternal and fetal genotypes are a potential mechanism for the onset or progression of pregnancy related diseases such as pre-eclampsia (PE). However, the optimal analytical approach and study design for evaluating incompatible maternal/offspring genotype combinations is unclear.

Methods

Using simulation, we estimated the type I error and power of incompatible maternal/offspring genotype models for two analytical approaches: logistic regression used with case-control mother/offspring pairs and the log-linear regression used with case-parent triads. We evaluated a real dataset consisting of maternal/offspring pairs with and without PE for incompatibility effects using the optimal analysis based …

Waiting For Child Developmental And Rehabilitation Services: An Overview Of Issues And Needs, Anton R. Miller, Robert Armstrong, Louise C. Mâsse, Anne F. Klassen, Jane Shen, Maureen E. O’Donnell

Paediatrics and Child Health, East Africa

Concern about the length of time that children, young people, and families may have to wait to access assessment, diagnostic, interventional, therapeutic, and supportive child developmental and rehabilitation (CDR) services is widespread, but adequate data collection and research on this issue remain limited. We review key concepts and issues relevant to waiting for CDR services from the published literature, a national workshop devoted to this topic, and international experience. We conclude that gaps in data, evidence, and consensus challenge our ability to address the issue of waiting for CDR services in a systematic way. A program of research coupled with …

Distinguishing Post-Treatment Changes From Recurrent Disease In Cholangiocarcinoma: A Case Report., Timothy N Showalter, A Omer Nawaz, Frederick M Fellin, Pramila R Anne, Ernest L Rosato, Adam P Dicker

Department of Radiation Oncology Faculty Papers

INTRODUCTION: Three-dimensional techniques for radiotherapy have expanded possibilities for partial volume liver radiotherapy. Characteristic, transient radiographic changes can occur in the absence of clinical radiation-induced liver disease after hepatic radiotherapy and must be distinguished from local recurrence. CASE PRESENTATION: In this report, we describe computed tomography changes after chemoradiotherapy for cholangiocarcinoma as an example of collaboration to determine the clinical significance of the radiographic finding. CONCLUSION: Because of improved three-dimensional, conformal radiotherapy techniques, consultation across disciplines may be necessary to interpret post-treatment imaging findings.

Section of Urology

Background: The importance of immuno-histological detection of neuroendocrine differentiation in prostatic adenocarcinoma with respect to disease at presentation and Gleason grade is gaining acceptance. There is limited literature on the relative significance of three commonly used markers of NE differentiation i.e. Chromogranin A (CgA), Neuron specific enolase (NSE) and Synaptophysin (Syn). In the current work we have assessed the correlation of immuno-histological detection of neuroendocrine differentiation in prostatic adenocarcinoma with respect to disease at presentation and Gleason grade and to determine the relative value of various markers.
Materials and Methods: Consecutive samples of malignant prostatic specimens (Transurethral resection of prostate …
