Abstract

Background

In addition to breast imaging, ultrasound offers the potential for characterizing and distinguishing between benign and malignant breast tissues due to their different microstructures and material properties. The aim of this study was to determine if high-frequency ultrasound (20-80 MHz) can provide pathology sensitive measurements for the ex vivo detection of cancer in margins during breast conservation surgery.

Methods

Ultrasonic tests were performed on resected margins and other tissues obtained from 17 patients, resulting in 34 specimens that were classified into 15 pathology categories. Pulse-echo and through-transmission measurements were acquired from a total of 57 sites on the …

Rhodococcus Equi Venous Catheter Infection: A Case Report And Review Of The Literature, Rosalinda Guerrero, Ashish Bhargava, Zeina Nahleh

Wayne State University Associated BioMed Central Scholarship

Abstract

Introduction

Rhodococcus equi is an animal pathogen that was initially isolated from horses and is being increasingly reported as a cause of infection in humans with impaired cellular immunity. However, this pathogen is underestimated as a challenging antagonist and is frequently considered to be a mere contaminant despite the potential for life-threatening infections. Most case reports have occurred in immunocompromised patients who have received organ transplants (for example kidney, heart, bone marrow) or those with human immunodeficiency virus infection. Infections often manifest as pulmonary involvement or soft tissue abscesses. Bacteremia related to R. equi infections of tunneled central venous …

Spatial-Temporal Analysis Of Non-Hodgkin Lymphoma In The Nci-Seer Nhl Case-Control Study, David C. Wheeler, Anneclaire J. De Roos, James R. Cerhan, Lindsay M. Morton, Richard Severson, Wendy Cozen, Mary H. Ward

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Exploring spatial-temporal patterns of disease incidence through cluster analysis identifies areas of significantly elevated or decreased risk, providing potential clues about disease risk factors. Little is known about the etiology of non-Hodgkin lymphoma (NHL), or the latency period that might be relevant for environmental exposures, and there are no published spatial-temporal cluster studies of NHL.

Methods

We conducted a population-based case-control study of NHL in four National Cancer Institute (NCI)-Surveillance, Epidemiology, and End Results (SEER) centers: Detroit, Iowa, Los Angeles, and Seattle during 1998-2000. Using 20-year residential histories, we used generalized additive models adjusted for known risk factors …

Rad6b Acts Downstream Of Wnt Signaling To Stabilize Β-Catenin: Implications For A Novel Wnt/Β-Catenin Target, Brigitte Gerard, Larry Tait, Pratima Nangia-Makker, Malathy Pv Shekhar

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Aberrant Wnt/β-catenin signaling is associated with breast cancer even though genetic mutations in Wnt signaling components are rare. We have previously demonstrated that Rad6B, an ubiquitin conjugating enzyme, stabilizes β-catenin via polyubiqutin modifications that render β-catenin insensitive to proteasomal degradation. Rad6B is a transcriptional target of β-catenin, creating a positive feedback loop between Rad6B expression and β-catenin activation.

Methods

To isolate subpopulations expressing high or low Rad6B levels, we transfected MDA-MB-231 or WS-15 human breast cancer cells with ZsGreen fluorescent reporter vector in which the expression of ZsGreen was placed under the control of Rad6B promoter. ZsGreen^{high …}

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Preeclampsia affects 3-8% of pregnancies and is a major cause of maternal and perinatal morbidity and mortality worldwide. This complex disorder is characterized by alterations in the immune and vascular systems and involves multiple organs. There is strong evidence for a genetic contribution to preeclampsia. Two different single nucleotide polymorphisms (SNPs) in the endoplasmic reticulum aminopeptidase 2 (ERAP2) gene were recently reported to be associated with increased risk for preeclampsia in two different populations. ERAP2 is expressed in placental tissue and it is involved in immune responses, inflammation, and blood pressure regulation; making it is an attractive preeclampsia …

Gray, Robert P. Garvin, David J. Carey, Wayne D. Lancaster, Gerard Tromp, Helena Kuivaniemi

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

The infrarenal abdominal aorta exhibits increased disease susceptibility relative to other aortic regions. Allograft studies exchanging thoracic and abdominal segments showed that regional susceptibility is maintained regardless of location, suggesting substantial roles for embryological origin, tissue composition and site-specific gene expression.

Results

We analyzed gene expression with microarrays in baboon aortas, and found that members of the HOX gene family exhibited spatial expression differences. HOXA4 was chosen for further study, since it had decreased expression in the abdominal compared to the thoracic aorta. Western blot analysis from 24 human aortas demonstrated significantly higher HOXA4 protein levels in thoracic …

Histone Deacetylases (Hdacs) In Xpc Gene Silencing And Bladder Cancer, Xiaoxin S. Xu, Le Wang, Judith Abrams, Gan Wang

Wayne State University Associated BioMed Central Scholarship

Abstract

Bladder cancer is one of the most common malignancies and causes hundreds of thousands of deaths worldwide each year. Bladder cancer is strongly associated with exposure to environmental carcinogens. It is believed that DNA damage generated by environmental carcinogens and their metabolites causes development of bladder cancer. Nucleotide excision repair (NER) is the major DNA repair pathway for repairing bulk DNA damage generated by most environmental carcinogens, and XPC is a DNA damage recognition protein required for initiation of the NER process. Recent studies demonstrate reduced levels of XPC protein in tumors for a majority of bladder cancer patients. …

A Protein Network-Guided Screen For Cell Cycle Regulators In Drosophila, Stephen T. Guest, Jingkai Yu, Dongmei Liu, Julie A. Hines, Maria A. Kashat, Russell L. Finley Jr

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Large-scale RNAi-based screens are playing a critical role in defining sets of genes that regulate specific cellular processes. Numerous screens have been completed and in some cases more than one screen has examined the same cellular process, enabling a direct comparison of the genes identified in separate screens. Surprisingly, the overlap observed between the results of similar screens is low, suggesting that RNAi screens have relatively high levels of false positives, false negatives, or both.

Results

We re-examined genes that were identified in two previous RNAi-based cell cycle screens to identify potential false positives and false negatives. We …

Phylogeny And Adaptive Evolution Of The Brain-Development Gene Microcephalin (Mcph1) In Cetaceans, Michael R. Mcgowen, Stephen H. Montgomery, Clay Clark, John Gatesy

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Representatives of Cetacea have the greatest absolute brain size among animals, and the largest relative brain size aside from humans. Despite this, genes implicated in the evolution of large brain size in primates have yet to be surveyed in cetaceans.

Results

We sequenced ~1240 basepairs of the brain development gene microcephalin (MCPH1) in 38 cetacean species. Alignments of these data and a published complete sequence from Tursiops truncatus with primate MCPH1 were utilized in phylogenetic analyses and to estimate ω (rate of nonsynonymous substitution/rate of synonymous substitution) using site and branch models of molecular evolution. We also tested …

The Pax Gene Eyegone Facilitates Repression Of Eye Development In Tribolium, Nazanin Zarinkamar, Xiaoyun Yang, Riyue Bao, Frank Friedrich, Rolf Beutel, Markus Friedrich

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

The Pax transcription factor gene eyegone (eyg) participates in many developmental processes in Drosophila, including the Notch signaling activated postembryonic growth of the eye primordium, global development of the adult head and the development of the antenna. In contrast to other Pax genes, the functional conservation of eyg in species other than Drosophila has not yet been explored.

Results

We investigated the role of eyg during the postembryonic development of the red flour beetle Tribolium castaneum. Our results indicate conserved roles in antennal but not in eye development. Besides segmentation defects in the antenna, Tribolium eyg knockdown animals …

Bio::Phylo-Phyloinformatic Analysis Using Perl, Rutger A. Vos, Jason Caravas, Klaas Hartmann, Mark A. Jensen, Chase Miller

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Phyloinformatic analyses involve large amounts of data and metadata of complex structure. Collecting, processing, analyzing, visualizing and summarizing these data and metadata should be done in steps that can be automated and reproduced. This requires flexible, modular toolkits that can represent, manipulate and persist phylogenetic data and metadata as objects with programmable interfaces.

Results

This paper presents Bio::Phylo, a Perl5 toolkit for phyloinformatic analysis. It implements classes and methods that are compatible with the well-known BioPerl toolkit, but is independent from it (making it easy to install) and features a richer API and a data model that is …

The Cns Microvascular Pericyte: Pericyte-Astrocyte Crosstalk In The Regulation Of Tissue Survival, Drew Bonkowski, Vladimir Katyshev, Roumen D. Balabanov, Andre Borisov, Paula Dore-Duffy

Wayne State University Associated BioMed Central Scholarship

Abstract

The French scientist Charles Benjamin Rouget identified the pericyte nearly 140 years ago. Since that time the role of the pericyte in vascular function has been difficult to elucidate. It was not until the development of techniques to isolate and culture pericytes that scientists have begun to understand the true impact of this unique cell in the maintenance of tissue homeostasis. In the brain the pericyte is an integral cellular component of the blood-brain barrier and, together with other cells of the neurovascular unit (endothelial cells, astrocytes and neurons) the pericyte makes fine-tuned regulatory adjustments and adaptations to promote …

Cathepsin B: A Potential Prognostic Marker For Inflammatory Breast Cancer, Mohamed A. Nouh, Mona M. Mohamed, Mohamed El-Shinawi, Mohamed A. Shaalan, Dora Cavallo-Medved, Hussein M. Khaled, Bonnie F. Sloane

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Inflammatory breast cancer (IBC) is the most aggressive form of breast cancer. In non-IBC, the cysteine protease cathepsin B (CTSB) is known to be involved in cancer progression and invasion; however, very little is known about its role in IBC.

Methods

In this study, we enrolled 23 IBC and 27 non-IBC patients. All patient tissues used for analysis were from untreated patients. Using immunohistochemistry and immunoblotting, we assessed the levels of expression of CTSB in IBC versus non-IBC patient tissues. Previously, we found that CTSB is localized to caveolar membrane microdomains in cancer cell lines including IBC, and …

Abstract

Background

Abdominal aortic aneurysm (AAA) is a complex disorder with multiple genetic risk factors. Using affected relative pair linkage analysis, we previously identified an AAA susceptibility locus on chromosome 19q13. This locus has been designated as the AAA1 susceptibility locus in the Online Mendelian Inheritance in Man (OMIM) database.

Methods

Nine candidate genes were selected from the AAA1 locus based on their function, as well as mRNA expression levels in the aorta. A sample of 394 cases and 419 controls was genotyped for 41 SNPs located in or around the selected nine candidate genes using the Illumina GoldenGate platform. …

The Impact Of Folate Deficiency On The Base Excision Repair Pathway: Analysis Of Enzyme Coordination In Response To Dna Damage And Imbalanced Repair, Amanda Pilling

Wayne State University Dissertations

The condition of folate deficiency has been implicated in carcinogenesis, with the strongest evidence formulated in colon cancer. The role of folate in DNA repair, DNA synthesis and methylation reactions renders this nutrient an valuable target for studying the onset and progression of cancer. Using molecular techniques to determine gene and protein expression, enzyme activity and methylation status elucidates the mechanism of DNA repair and damage in folic acid deficient animals in response to carcinogen. The findings presented in this study indicate failure to remove and repair damage in the condition of folate deficiency and suggest that the accumulation of …

Wayne State University Dissertations

Estrogen sulfotransferase (SULT1E1) catalyzes the sulfonation of estrogens, which limits estrogen mitogenicity. TaqMan Gene Expression assays were used to profile the mRNA expression of estrogen receptor (ERα and ERβ) and estrogen metabolism enzymes including cytosolic sulfotransferases (SULT1E1, SULT1A1, SULT2A1, and SULT2B1), steroid sulfatase (STS), aromatase (CYP19), 17β-hydroxysteroid dehydrogenases (17βHSD1 and 2), CYP1B1, and catechol-O-methyltransferase (COMT) in an MCF10A-derived lineage cell culture model for basal-like human breast cancer progression and in ERα-positive luminal MCF7 breast cancer cells. Low levels of ERα and ERβ mRNA were present in MCF10A-derived cell lines. SULT1E1 mRNA was more abundant in confluent relative to subconfluent MCF10A …

Hedgehog Signaling: A Potential Therapeutic Target For Non-Small Cell Lung Cancer, Ma'in Yehya Maitah

Wayne State University Dissertations

The American Cancer Society estimated that 222,520 Americans were diagnosed with lung cancer and 157,300 died of lung cancer in 2010 (Jemal et al. 2009, 225-249;Jemal et al. 2011, 69-90). The clinical outcome of patients diagnosed with non-small cell lung cancer (NSCLC), the major lung cancer sub-types, is very poor, which calls for innovative research for finding novel therapeutic targets and agents for better treatment outcome.

Emerging evidences have suggested that a phenomenon called Epithelial-to-Mesenchymal Transition (EMT), which shares similar molecular characteristics with cancer stem-like cells, contributes to lung cancer treatment failure. In view of the fact that EMT process …

Perceived Familial Socialization And Ethnic Identity: Factors Associated With Physical Activity, Eating Behavior Patterns, And Social Physique Anxiety In African American Middle Adolescents, Nutrena H. Tate

Wayne State University Dissertations

Purpose: African American adolescents experience higher rates of obesity and have an increased risk of obesity related diseases than Caucasian American adolescents. Despite culturally sensitive obesity preventive interventions, obesity rates are increasing within the African American adolescent population. Current obesity interventions claim to be culturally sensitive, but do not address how ethnic identity and parental influences on body image and body change may affect the efficacy of the interventions. The purpose of this study was to examine the sociocultural factors related to weight behaviors and cognitions in African American adolescents. Differences based on socioeconomic status (SES), gender, and residential status …

Expression Of Microbial Rhodopsins In Retinal Neurons With Subcellular Targeting Motifs: For The Study Of The Structure/Function Of Aii Amacrine Cells And For Vision Restoration, Chaowen Wu

Wayne State University Dissertations

Protein-targeting motifs serve as addresses for subcellular protein localization. This feature of targeting-motifs was used to study the retina. The first part of the dissertation reports in the axonless spiking AII amacrine cell of the mammalian retina a dendritic process sharing organizational and functional similarities with the axon initial segment, the typical site of action potential initiation. This process was revealed through viral-mediated expression of channelrhodopsin-2-GFP (ChR2-GFP) with the AIS-targeting motif of sodium channels (NavII-III) and was shown to be the site of spike initiation. The second part of the dissertation aimed to improve microbial rhodopsin-mediated gene therapy for vision …

Examining The Relationship Among Physical And Psychological Health, Parent And Peer Attachment, And Cyberbullying In Adolescents In Urban And Suburban Environments, Jemica Monique Carter

Wayne State University Dissertations

Cyberbullying is a new phenomenon that has received substantial attention via media. An extensive review of the literature revealed limited nursing research on this topic. The purpose of this study was to examine the impact of cyberbullying on adolescents' physical (e.g., headache, stomachache, etc.) and psychosocial (e.g., self-esteem, depression, post traumatic stress syndrome, etc.) outcomes. Individuals who experience repeated traditional bullying are at increased risk for experiencing repeated incidents of cyberbullying. Research has shown that effects of cyberbullying may be more traumatic than traditional bullying because victims can be bullied 24 hours and 7 days a week, on and off …

The Effects Of Racially-Motivated Emotional Arousal On The Eating Behaviors Of African American Women, Lenwood W. Hayman

Wayne State University Dissertations

Disparities between African Americans and Caucasians remain vast across a wide variety of health indicators. Chronic stress has been identified as a risk factor for a variety of chronic illnesses and poor health outcomes. One type of chronic stress that has been linked to health disparities is the stress associated with experiences of racial discrimination. The stress African Americans encounter as a result of their racist experiences contributes to a chronic elevation of their physiological stress response. In addition to stress, a major risk factor for coronary heart disease and diabetes is obesity, which has been established as a major …

Hospital Quality And Medicare Payment: A Theoretical And Empirical Investigation, Jinghua Huang

Wayne State University Dissertations

Does Medicare's payment rate for a hospital stay influence the quality of care received by a patient? We examine this question, theoretically and empirically. First, a model is developed which generates the key hypothesis -- that Medicare's payment rate per admission should be positively related to care quality. We then test this hypothesis by estimating the relationship between Medicare's DRG payment for pneumonia, heart failure and heart attacks and care quality, using clinically-recognized measures of the quality of pneumonia care, heart failure care and heart attack care. Newly available data on acute hospitals in 2007 from "Hospital Compare" (maintained by …

Social Workers' Knowledge And Attitudes About Treating Children With Attention Deficit Hyperactivity Disorder, Angelah Dawn Gomez

Wayne State University Theses

The current research seeks to understand how social work students and social work professionals increase their knowledge about AD/HD and how they formulate their attitudes about the disorder. The literature provided illustrates the many components of AD/HD risks, etiology, treatments, and professional opinions about the disorder. AD/HD is one of the most studied childhood mental health disorders in the nation. However, there is little research providing insight to social workers' knowledge and attitudes about the disorder. This is especially alarming because social workers are one of the largest professional populations to provide mental health services to children and their families. …
