The Influence Of Interleukin-4 On Ligament Healing, Connie S. Chamberlain, Ellen M. Leiferman, Kayt E. Frisch, Sijian Wang, Xipei Yang, Stacey L. Brickson, Ray Vanderby

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Despite a complex cascade of cellular events to reconstruct the damaged extracellular matrix, ligament healing results in a mechanically inferior scarred ligament. During normal healing, granulation tissue expands into any residual normal ligamentous tissue (creeping substitution), resulting in a larger region of healing, greater mechanical compromise and an inefficient repair process. To control creeping substitution and possibly enhance the repair process, the antiinflammatory cytokine, interleukin-4 (IL-4), was administered to rats before and after rupture of their medial collateral ligaments. In vitro experiments showed a time-dependent effect on fibroblast proliferation after IL-4 treatment. In vivo treatments with IL-4 (100 ng/mL IV) …

Ultrasound Echo Is Related To Stress And Strain In Tendon, Sarah Duenwald, Hirohito Kobayashi, Kayt E. Frisch, Roderic Lakes, Ray Vanderby Jr.

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

The mechanical behavior of tendons has been well studied in vitro. A noninvasive method to acquire mechanical data would be highly beneficial. Elastography has been a promising method of gathering in vivo tissue mechanical behavior, but it has inherent limitations. This study presents acoustoelasticity as an alternative ultrasound-based method of measuring tendon stress and strain by reporting a relationship between ultrasonic echo intensity (B-mode ultrasound image brightness) and mechanical behavior of tendon in vitro. Porcine digital flexor tendons were cyclically loaded in a mechanical testing system while an ultrasonic echo response was recorded. We report that echo intensity …

Management Of Hypertension Among Patients With Coronary Heart Disease, O. Olafiranye, F. Zizi, P. Brimah, G. Jean-Louis, A. N. Makaryus, S. Mcfarlane, G. Ogedegbe

Journal Articles

Evidence suggests that coronary heart disease (CHD) is the most common outcome of hypertension. Hypertension accelerates the development of atherosclerosis, and sustained elevation of blood pressure (BP) can destabilize vascular lesions and precipitate acute coronary events. Hypertension can cause myocardial ischemia in the absence of CHD. These cardiovascular risks attributed to hypertension can be reduced by optimal BP control. Although several antihypertensive agents exist, the choice of agent and the appropriate target BP for patients with CHD remain controversial. In this succinct paper, we examine the evidence and the mechanisms for the linkage between hypertension and CHD and we discuss …

The Nurse's Knowledge Of Blood Conservation As A Part Of Blood Management, Lindsey Putnam Austin

Nursing Theses and Capstone Projects

Medicine has historically regarded blood transfusion as an integral component of major surgery or illness. However, clinical studies have shown that allogeneic blood transfusions are associated with increased morbidity and decreased survival. Knowledge of this research and the concepts of blood conservation so as to avoid unnecessary blood transfusions is needed in order to deliver holistic care and serve as patient advocate. This knowledge reaches every specialty of nursing care.

This study of the nurse's knowledge of blood conservation as a part of blood management utilizes The Conservation Model developed by Myra E. Levine in 1973. Levine's work is a …

The Influence Of Macrophage Depletion On Ligament Healing, Connie S. Chamberlain, Ellen M. Leiferman, Kayt E. Frisch, Sijian Wang, Xipei Yang, Nico Van Rooijen, Geoff S. Baer, Stacey L. Brickson, Ray Vanderby

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Despite a complex cascade of cellular events to reconstruct damaged extracellular matrix (ECM), ligament healing results in a mechanically inferior, scar-like tissue. During normal healing, the number of macrophages significantly increases within the wound site. Then, granulation tissue expands into any residual, normal ligamentous tissue (creeping substitution), resulting in a larger region of healing, greater mechanical compromise, and an inefficient repair process. To study the effects of macrophages on the repair process, bilateral, surgical rupture of their medial collateral ligaments (MCLs) was done on rats. Treatment animals received liposome-encapsulated clodronate, 2 days before rupture to ablate phagocytosing macrophages. Ligaments were …

Identification Of Genes Involved In Hematopoietic Stem Cell Differentiation And Leukemia Differentiation And Leukemia, Jasjeet Bhullar

Theses, Dissertations and Capstones

Hematopoiesis is maintained by a proper balance between self renewal and multipotent differentiation of the hematopoietic stem cells (HSC). Acute myelogenous leukemia (AML) is characterized by the blockage in the differentiation of HSC, while self renewal and proliferation is preserved. It is important to understand the mechanisms involved in the inhibition of hematopoietic differentiation and maintenance of the HSC state in order to develop better therapies for AML. In these studies I have explored the role of Hsp90, omega-3 fatty acids and YB-1 in hematopoietic differentiation. EML, a hematopoietic precursor cell line, was used as a model for the hematopoietic …

The Effects Of Smoking On Pregnant Women, Meir Cohen

The Science Journal of the Lander College of Arts and Sciences

Smoking during pregnancy is accepted as the most significant avoidable risk factor for an unsuccessful pregnancy result. Smoking is linked with fetal growth restriction, and increasing evidence also suggests that smoking can cause stillbirth, preterm birth, placental abruption, and possibly sudden infant death syndrome. Smoking during pregnancy is also associated with enhanced risks of spontaneous abortions, ectopic pregnancies, and placenta previa, and it might increase risks of behavioral disorders in childhood. Studies have shown with randomized controlled trials, that smoking intervention during pregnancy has had limited success. Smoking during pregnancy continues to be an important risk factor for maternal and …

Journal Articles: Pulmonary & Critical Care Med

Fibroblasts are heterogeneous mesenchymal cells that play important roles in the production and maintenance of extracellular matrix. Although their heterogeneity is recognized, progenitor progeny relationships among fibroblasts and the factors that control fibroblast differentiation are poorly defined. The current study was designed to develop a reliable method that would permit in vitro differentiation of fibroblast-like cells from human and murine embryonic stem cells (ESCs). Undifferentiated ESCs were differentiated into embryoid bodies (EBs) with differentiation media. EBs were then cast into type I collagen gels and cultured for 21 d with basal media. The spindle-shaped cells that subsequently grew from the …

THE ROLE OF THE SPARC ACIDIC DOMAIN AND EGF-LIKE MODULE IN GLIOMA MIGRATION, INVASION, AND SIGNALING

HEATHER M. MCCLUNG

Advisor: Sandra A. Rempel, Ph.D.

Major: Pharmacology

Degree: Doctor of Philosophy

We have previously shown that Secreted Protein Acidic and Rich in Cysteine (SPARC) is upregulated in all astrocytoma grades and increases tumor cell migration and invasion. It is thought that different domains within the protein may regulate SPARC functions, suggesting domain-specific targeting to inhibit invasion. To enhance our understanding of SPARC-mediated invasion, we first confirm, at the protein level, our previous cDNA array results, that SPARC increases expression of the …

Estrogen Sulfotransferase (Sult1e1) Expression And Function In Mcf10a-Series Breast Epithelial Cells: Role As A Modifier Of Breast Carcinogenesis And Regulation By Proliferation State, Jiaqi Fu

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 …

Potential For Interdependent Development Of Trna Determinants For Aminoacylation And Ribosome Decoding., Cuiping Liu, Howard Gamper, Hanqing Liu, Barry S Cooperman, Ya-Ming Hou

Department of Biochemistry and Molecular Biology Faculty Papers

Although the nucleotides in tRNA required for aminoacylation are conserved in evolution, bacterial aminoacyl-transfer RNA synthetases are unable to acylate eukaryotic tRNA. The cross-species barrier may be due to the absence of eukaryote-specific domains from bacterial aminoacyl-transfer RNA synthetases. Here we show that whereas Escherichia coli CysRS cannot acylate human tRNA(Cys), the fusion of a eukaryote-specific domain of human CysRS overcomes the cross-species barrier in human tRNA(Cys). In addition to enabling recognition of the sequence differences in the tertiary core of tRNA(Cys), the fused eukaryotic domain redirects the specificity of E. coli CysRS from the A37 present in bacterial tRNA(Cys) …

A Sibling Case-Control Study Of Maternal Prenatal Body Mass Index As A Risk Factor For Autism Spectrum Disorder, Ruth Ann Hendrix

Walden Dissertations and Doctoral Studies

The prevalence of autism spectrum disorder (ASD) is estimated to be one in every 150 births. While both genetic and postpartum environmental exposure have been linked to ASD, prenatal maternal weight has not been investigated. The objective of the study is to assess whether overweight or obesity at pregnancy is an important risk factor for the diagnosis of ASD in offspring. A case-control study was designed to answer this question using the public health ecosocial theory. The study population consisted of 70 mothers, who were recruited via the Internet using the viral expansion loop. Multiple logistic regression analysis was used …

Spirituality And Depression In Parents With Children In Oncology Or Hematology Treatment, Kurt D. Soell

Walden Dissertations and Doctoral Studies

The psychological burden of cancer treatment affects not only child patients but also their parents. There is extensive literature on the positive influence of spirituality on the cancer patient. But there is a gap in the literature on the potential healing influence of spirituality on the parent of the cancer or hematology patient. The purpose of this study was to examine the relationship between spirituality and parents' levels of depression and anxiety during their child's hematological or oncology treatment. Using the transtheoretical model of change, a purposive sample of 48 parents of children undergoing cancer or hematology treatment completed a …

Photodisruption In Ocular Tissue Near And At The Boundary Between The Anterior Chamber And Crystalline Lens, Richard Ty Olmstead

Electronic Theses and Dissertations

Lasers have been involved in Ophthalmology in the treatment of myopia and hyperopia for several years. Laser systems have transformed patients‟ quality of life, freeing them from the need for glasses, as in the case of LASIK. Ultrafast lasers have played an important role in surgery of the eye. In LASIK, they are used to cut the flap that is lifted to expose the stroma for UV Excimer laser treatment of this region. They are now being used for surgery deeper into the eye,for instance, treating the lens as part of treatments for cataract surgery. The use of ultrafast lasers …

Tissue-Specific Regulation Of Mouse Microrna Genes In Endoderm-Derived Tissues., Yan Gao, Jonathan Schug, Lindsay B Mckenna, John Le Lay, Klaus H Kaestner, Linda E Greenbaum

Department of Cancer Biology Faculty Papers

MicroRNAs fine-tune the activity of hundreds of protein-coding genes. The identification of tissue-specific microRNAs and their promoters has been constrained by the limited sensitivity of prior microRNA quantification methods. Here, we determine the entire microRNAome of three endoderm-derived tissues, liver, jejunum and pancreas, using ultra-high throughput sequencing. Although many microRNA genes are expressed at comparable levels, 162 microRNAs exhibited striking tissue-specificity. After mapping the putative promoters for these microRNA genes using H3K4me3 histone occupancy, we analyzed the regulatory modules of 63 microRNAs differentially expressed between liver and jejunum or pancreas. We determined that the same transcriptional regulatory mechanisms govern tissue-specific …

Nonsurgical Treatment Options For Basal Cell Carcinoma, Mary H. Lien, Vernon K. Sondak

Dermatology & Cutaneous Surgery Faculty Publications

Basal cell carcinoma (BCC) remains the most common form of nonmelanoma skin cancer (NMSC) in Caucasians, with perhaps as many as 2 million new cases expected to occur in the United States in 2010. Many treatment options, including surgical interventions and nonsurgical alternatives, have been utilized to treat BCC. In this paper, two non-surgical options, imiquimod therapy and photodynamic therapy (PDT), will be discussed. Both modalities have demonstrated acceptable disease control rates, cosmetically superior outcomes, and short-term cost-effectiveness. Further studies evaluating long-term cure rates and long-term cost effectiveness of imiquimod therapy and PDT are needed.

Requirement Of Argininosuccinate Lyase For Systemic Nitric Oxide Production, Ayelet Erez, Sandesh Cs. Nagamani, Oleg A. Shchelochkov, Muralidhar H. Premkumar, Philippe M.

Department of Emergency Medicine

Nitric oxide (NO) is crucial in diverse physiological and pathological processes. We show that a hypomorphic mouse model of argininosuccinate lyase (encoded by Asl) deficiency has a distinct phenotype of multiorgan dysfunction and NO deficiency. Loss of Asl in both humans and mice leads to reduced NO synthesis, owing to both decreased endogenous arginine synthesis and an impaired ability to use extracellular arginine for NO production. Administration of nitrite, which can be converted into NO in vivo, rescued the manifestations of NO deficiency in hypomorphic Asl mice, and a nitric oxide synthase (NOS)-independent NO donor restored NO-dependent vascular reactivity in …

Targeted Decorin Gene Therapy Delivered With Adeno-Associated Virus Effectively Retards Corneal Neovascularization In Vivo, Rajiv R. Mohan, Jonathan C. K. Tovey, Ajay Sharma, Gregory S. Schultz, John W. Cowden, Ashish Tandon

Pharmacy Faculty Articles and Research

Decorin, small leucine-rich proteoglycan, has been shown to modulate angiogenesis in nonocular tissues. This study tested a hypothesis that tissue-selective targeted decorin gene therapy delivered to the rabbit stroma with adeno-associated virus serotype 5 (AAV5) impedes corneal neovascularization (CNV) in vivo without significant side effects. An established rabbit CNV model was used. Targeted decorin gene therapy in the rabbit stroma was delivered with a single topical AAV5 titer (100 μl; 5x10^12 vg/ml) application onto the stroma for two minutes after removing corneal epithelium. The levels of CNV were examined with stereomicroscopy, H&E staining, lectin, collagen type IV, CD31 immunocytochemistry and …
