Objective: Since dentures can serve as a reservoir for halitosis-causing oral bacteria, halitosis development is a concern for denture wearers. In this study, we surveyed the prevalence of four selected halitosis-related species (Fusobacterium nucleatum, Tannerella forsythia, Veillonella atypica and Klebsiella pneumoniae) in clinical denture plaque samples, and developed denture biofilm models for these species in vitro to facilitate assessment of antimicrobial treatment efficacy. Design: Denture plaque from ten healthy and ten denture stomatitis patients was screened for the presence of aforementioned four species by PCR. Biofilm formation by these halitosis-associated species on the surfaces of denture …

Ideology Masquerading As Science: The Case Of Endocrine Disrupter Screening Programmes, Troy Seidle
Troy Seidle, PhD
The global move to develop novel testing methods and strategies to identify suspected endocrine disrupting chemicals offers a unique opportunity to move away from traditional animal testing paradigms in this new area of regulatory concern. Regrettably, the programmes under development, both in the USA and internationally through the OECD, have thus far failed to consider in vitro and other nonanimal test methods as more than “pre-screening” or “priority-setting” tools in a larger, animal-based testing strategy. Validation efforts to date have focused almost exclusively on the modification of existing animal tests to detect “endocrine effects”, with no demonstrable effort to promote …

Hemozoin (Hz) is the crystalline detoxification product of hemoglobin in Plasmodium-infected erythrocytes. We previously proposed that Hz can carry plasmodial DNA into a subcellular compartment that is accessible to Toll-like receptor 9 (TLR9), inducing an inflammatory signal. Hz also activates the NLRP3 inflammasome in primed cells. We found that Hz appears to colocalize with DNA in infected erythrocytes, even before RBC rupture or phagolysosomal digestion. Using synthetic Hz coated in vitro with plasmodial genomic DNA (gDNA) or CpG oligodeoxynucleotides, we observed that DNA-complexed Hz induced TLR9 translocation, providing a priming and an activation signal for inflammasomes. After phagocytosis, Hz and …

Cyclic paroxysm and high fever are hallmarks of malaria and are associated with high levels of pyrogenic cytokines, including IL-1beta. In this report, we describe a signature for the expression of inflammasome-related genes and caspase-1 activation in malaria. Indeed, when we infected mice, Plasmodium infection was sufficient to promote MyD88-mediated caspase-1 activation, dependent on IFN-gamma-priming and the expression of inflammasome components ASC, P2X7R, NLRP3 and/or NLRP12. Pro-IL-1beta expression required a second stimulation with LPS and was also dependent on IFN-gamma-priming and functional TNFR1. As a consequence of Plasmodium-induced caspase-1 activation, mice produced extremely high levels of IL-1beta upon a second …

Web Tool For Estimating The Cancer Hazard Rates In Aging., Tengiz Mdzinarishvili, Alexander Sherman, Oleg Shats, Simon Sherman
Journal Articles: Eppley Institute
A computational approach for estimating the overall, population, and individual cancer hazard rates was developed. The population rates characterize a risk of getting cancer of a specific site/type, occurring within an age-specific group of individuals from a specified population during a distinct time period. The individual rates characterize an analogous risk but only for the individuals susceptible to cancer. The approach uses a novel regularization and anchoring technique to solve an identifiability problem that occurs while determining the age, period, and cohort (APC) effects. These effects are used to estimate the overall rate, and to estimate the population and individual …
Increased Risk For Vitamin D Deficiency In Obese Children With Both Celiac Disease And Type 1 Diabetes, Nithya Setty-Shah, Louise S. Maranda, Benjamin U. Nwosu
Increased Risk For Vitamin D Deficiency In Obese Children With Both Celiac Disease And Type 1 Diabetes, Nithya Setty-Shah, Louise S. Maranda, Benjamin U. Nwosu
Benjamin U. Nwosu
Background. It is unknown whether the coexistence of type 1 diabetes (T1D) and celiac disease (CD) increases the risk for vitamin D deficiency.
Aims. To determine the vitamin D status and the risk for vitamin D deficiency in prepubertal children with both T1D and CD compared to controls, TID, and CD.
Subjects and Methods. Characteristics of 62 prepubertal children of age 2–13 y with either CD + T1D (� = 22, 9.9 ± 3.1 y), CD only (� = 18, 8.9 ± 3.3 y), or T1D only (� = 22, 10.1 ± 2.8 y) were compared to 49 controls of …
Overcoming Barriers To Screening For Anal Intraepithelial Neoplasia For Persons Living With Hiv, Brandon Hastings
Overcoming Barriers To Screening For Anal Intraepithelial Neoplasia For Persons Living With Hiv, Brandon Hastings
Doctor of Nursing Practice (DNP) Projects
Screening has proven an effective strategy in the management of diseases that plague the population. This technique has proven to be most effective when screening is conducted with those who are most at risk for developing the targeted illness and when the frequency of screening follows set guidelines. Currently there are no nationally recognized screening guidelines for anal intraepithelial neoplasia (AIN). Screening for AIN stands to reduce overall incidence of anal squamous cell carcinoma through destruction of the dysplastic cells before they become cancerous. The goals of this project were to identify the patient population that stands to benefit the …
Combating Hiv/Aids In Marginalized Communities: Papua And West Papua Provinces, Indonesia, Bani Cheema
Combating Hiv/Aids In Marginalized Communities: Papua And West Papua Provinces, Indonesia, Bani Cheema
Master's Theses
My study focuses on foreign aid and local initiatives for HIV/AIDS prevention in eastern Indonesia using the provinces of Papua and West Papua as a case study. The two provinces are home to indigenous tribal groups that are socioeconomically marginalized and most affected by the epidemic. My research investigates behavior change communication as a principal strategy undertaken by multiple organizations for HIV/AIDS prevention in this region. I take a qualitative approach by examining the effectiveness of this strategy in local communities and by revealing social and cultural barriers that impede success. Obstacles that negatively impact prevention efforts include structural violence, …
A Comparison Of Clinical Trial And Model-Based Cost Estimates In Glaucoma – The Case Of Repeat Laser Trabeculoplasty In Ontario, Omar Akhtar
Electronic Thesis and Dissertation Repository
Background and objective: For cost-effectiveness analyses (CEA) of glaucoma interventions to be of use they require valid and accurate cost and effectiveness data. Costs remain understudied relative to effectiveness. The impact of cost estimation methods on resultant estimates is unknown in glaucoma. Direct measurement of costs is labour-intensive and expensive. Decision-analytic modelling of costs using literature sources, expert opinion, institutional experience and assumptions provides a quicker, less laborious alternative to empirical costing. A lack of long-term effectiveness data in chronic diseases like glaucoma means that modelling is widespread and inevitable, both for CEAs and budget impact projections. The same problem …
Prostate Cancer Microparticles As A Next Generation Screening Tool For Prostate Cancer, Khurram M. Siddiqui
Prostate Cancer Microparticles As A Next Generation Screening Tool For Prostate Cancer, Khurram M. Siddiqui
Electronic Thesis and Dissertation Repository
Currently available screening tests for prostate cancer (PCa) are neither very sensitive nor specific. Microparticles (MP) are submicron tumor cell fragments released by PCa cells into the circulation and offer a possible means of sampling the tumor. We evaluated the utility of a MP blood test using nanoscale flow cytometry to distinguish patients with PCa from patients with benign prostatic hyperplasia (BPH). We used monoclonal antibodies against prostate specific membrane antigen, gastrin releasing peptide receptor and ghrelin peptide ligand.
We found higher but statistically insignificant, PSMA and Ghrelin dual +ve MP counts in the BPH group. Our results show that …

Brindley, Carlos Lopes, Lucio L. Santos
Microbiology, Immunology, and Tropical Medicine Faculty Publications
Background
Bladder cancer is a significant health problem in rural areas of Africa and the Middle East where Schistosoma haematobium is prevalent, supporting an association between malignant transformation and infection by this blood fluke. Nevertheless, the molecular mechanisms linking these events are poorly understood. Bladder cancers in infected populations are generally diagnosed at a late stage since there is a lack of non-invasive diagnostic tools, hence enforcing the need for early carcinogenesis markers.
Methodology/Principal Findings
Forty-three formalin-fixed paraffin-embedded bladder biopsies of S. haematobium-infected patients, consisting of bladder tumours, tumour adjacent mucosa and pre-malignant/malignant urothelial lesions, were screened for bladder …

Post-menopausal osteoporosis is a common syndrome in the United States. The cessation of estrogen signaling coupled with the production of pro-inflammatory cytokines from sleep deprivation leads to an even greater risk of post-menopausal osteoporosis by creating an imbalance between osteoblasts and osteoclasts. With estrogen no longer present to regulate the concentration of osteoclasts and pro-inflammatory cytokines increasing production of osteoclasts, bone is degraded at a faster rate than it is formed. One of the most common treatments for osteoporosis is Zolendronate (a nitrogenous bisphosphonate), which decreases the number of osteoclasts in bone. This preliminary study looked at the effects on …

Cloned Microglias With Novel Delivery System In Multiple Sclerosis, Abdul Mannan Baig Dr.
Department of Biological & Biomedical Sciences
Multiple Sclerosis (MS) is a chronic inflammatory neurological disease of the Central Nervous System (CNS), characterized by demyelination and activation of microglia. Mitochondrial mutations and dysfunctions in microglial cells are thought to contribute to the detrimental effects of neuroinflammation seen in MS. The Somatic Nuclear Transfer (SCNT) technology offers a more practical mode of therapy in MS, this method would attempt to dilute and/or progressively replace the mutated and activated microglia with cloned Olfactory Ensheathing Cells (OEC) with remyelinating and scavenging properties which would attempt to limit the progression of MS. Applying SCNTderived Embryonic Stem (ES) cells based therapy by …

Understanding Ten-Eleven Translocation-2 In Hematological And Nervous Systems, Feng Pan
Understanding Ten-Eleven Translocation-2 In Hematological And Nervous Systems, Feng Pan
FIU Electronic Theses and Dissertations
I proposed the study of two distinct aspects of Ten-Eleven Translocation 2 (TET2) protein for understanding specific functions in different body systems.
In Part I, I characterized the molecular mechanisms of Tet2 in the hematological system. As the second member of Ten-Eleven Translocation protein family, TET2 is frequently mutated in leukemic patients. Previous studies have shown that the TET2 mutations frequently occur in 20% myelodysplastic syndrome/myeloproliferative neoplasm (MDS/MPN), 10% T-cell lymphoma leukemia and 2% B-cell lymphoma leukemia. Genetic mouse models also display distinct phenotypes of various types of hematological malignancies. I performed 5-hydroxymethylcytosine (5hmC) chromatin immunoprecipitation sequencing (ChIP-Seq) and RNA …
Investigating Cortical Changes In Cervical Spondylotic Myelopathy Using Functional Magnetic Resonance Imaging, Proton Magnetic Resonance Spectroscopy And Diffusion Tensor Imaging, Izabela Kowalczyk
Electronic Thesis and Dissertation Repository
Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord dysfunction in older adults. CSM can present abruptly with severe symptoms of neurological impairment or insidiously with a slow stepwise deterioration. There is no current imaging modality or biomarker that can help predict which patient will successfully respond to conservative versus surgical treatment. The goal of this thesis was to follow CSM patients longitudinally to assess how brain function, metabolism, and structure correlate to clinical outcomes in the context of recovering neurological function following surgery.
Chapter 1 of this thesis will provide a detailed literature review of the …

Are Patients At The Centre Of Care?: A Qualitative Exploration Of Myotonic Dystrophy Type 1 (Dm1), Kori A. Ladonna
Electronic Thesis and Dissertation Repository
Health care for individuals living with myotonic dystrophy (DM1)—an uncommon, life-limiting neurological condition for which there are few treatments—may be challenged by patients’ symptoms including cognitive and behavioral impairments. Is patient-centered care—which incorporates the values, experiences and expertise of patients and their caregivers—feasible or achievable? Uncovering patients’ and their caregivers’ experiences of living with DM1, their health care expectations, and their health care providers’ (HCP) perspectives about care is essential for examining patient-centered care in this population. Therefore, the purpose of this research is to: (1) add patients’ and caregivers’ voices to the literature, (2) explore on-going care provision for …

Michael Greger, MD, FACLM
What we eat is rapidly becoming an issue of global concern. With food shortages, the rise in chronic disease, and global warming, the impact of our dietary choices seems more relevant today than ever. Globally, a transition is taking place toward greater consumption of foods of animal origin, in lieu of plantbased diets. With this transition comes intensification of animal agriculture that in turn is associated with the emergence of zoonotic infectious diseases, environmental degradation, and the epidemics of chronic disease and obesity. Health professionals should be aware of these trends and consider them as they promote healthier and more …

Syndecan 4 Is Required For Endothelial Alignment In Flow And Atheroprotective Signaling, Nicolas Baeyens, Mary Jo Mulligan-Kehoe, Federico Corti, David D. Simon, Tyler D. Ross, John M. Rhodes, Thomas Z. Wang
Dartmouth Scholarship
Atherosclerotic plaque localization correlates with regions of disturbed flow in which endothelial cells (ECs) align poorly, whereas sustained laminar flow correlates with cell alignment in the direction of flow and resistance to atherosclerosis. We now report that in hypercholesterolemic mice, deletion of syndecan 4 (S4−/−) drastically increased atherosclerotic plaque burden with the appearance of plaque in normally resistant locations. Strikingly, ECs from the thoracic aortas of S4−/− mice were poorly aligned in the direction of the flow. Depletion of S4 in human umbilical vein endothelial cells (HUVECs) using shRNA also inhibited flow-induced alignment in vitro, which was rescued by re-expression …

Genetic and molecular signatures have been incorporated into cancer prognosis prediction and treatment decisions with good success over the past decade. Clinically, these signatures are usually used in early-stage cancers to evaluate whether they require adjuvant therapy following surgical resection. A molecular signature that is prognostic across more clinical contexts would be a useful addition to current signatures. We defined a signature for the ubiquitous tissue factor, E2F4, based on its shared target genes in multiple tissues. These target genes were identified by chromatin immunoprecipitation sequencing (ChIP-seq) experiments using a probabilistic method. We then computationally calculated the regulatory activity score …
An Examination Of Factors That Influence Health Behaviors Among Low Income African American Women With Type 2 Diabetes In Memphis, Tn: A Qualitative Inquiry Using Mixed Methods, Adole Muruako

Community Health Worker Interventions For Latinos With Type 2 Diabetes: A Systematic Review Of Randomized Controlled Trials, Tariana V. Little, Monica L. Wang, Eida M. Castro, Julio Jiménez, Milagros C. Rosal
Tariana V. Little
This systematic review aimed to synthesize glucose (HbA1c) outcomes of community health worker (CHW)-delivered interventions for Latinos with type 2 diabetes that were tested in randomized controlled trials and to summarize characteristics of the targeted populations and interventions, including the background, training, and supervision of the CHWs. Searches of PubMed and Google Scholar databases and references from selected articles identified 12 studies that met the inclusion criteria. Of these, seven reported statistically significant improvements in HbA1c. Study participants were largely low-income, female, and Spanish-speaking and had uncontrolled diabetes. The CHWs led the interventions alone, in pairs, or as part of …

Repeated Transradial Catheterization: Feasibility, Efficacy, And Safety, Marinos A Charalambous, Savvas S Constantinides, Michael A Talias, Elpidoforos S Soteriades, Christos P Christou
The Texas Heart Institute Journal
Transradial access is an alternative to the transfemoral approach in coronary interventions. It results in less access-site bleeding, shorter hospital stays, lower costs, and less pain for the patient. However, some authors have suggested that the transradial approach might lead to radial artery occlusion, which precludes repeated same-artery catheterizations. Using data from our center, we evaluated the feasibility, safety, and efficacy of repeated transradial catheterization.
We reviewed the 3,006 transradial catheterizations performed at our center from 2006 through 2009. Patients who had undergone at least one repeated transradial catheterization were identified, their cases monitored through 2012, and their baseline characteristics …

Brachiocephalic Artery Cannulation In Proximal Aortic Surgery That Requires Circulatory Arrest, Mehmet Unal, Oguz Yilmaz, Ilker Akar, Ilker Ince, Cemal Aslan, Fatih Koc, Haluk Kafali
The Texas Heart Institute Journal
The brachiocephalic artery is an alternative cannulation site in the repair of ascending aortic lesions that require circulatory arrest. We evaluate the effectiveness and safety of this technique.
Proximal aortic surgery was performed in 32 patients from 2006 through 2012 via brachiocephalic artery cannulation and circulatory arrest. Twenty-four (75%) of the patients were men. The mean age was 48.69 ± 9.43 years (range, 30–68 yr). Twelve had type I dissection, 2 had type II dissection, and 18 had true aneurysms of the ascending aorta. All operations were performed through a median sternotomy. The arterial cannula was inserted through an 8-mm …

Aortic Valve Reconstruction With Use Of Pericardial Leaflets In Adults With Bicuspid Aortic Valve Disease: Early And Midterm Outcomes, Meong Gun Song, Hyun Suk Yang, Jong Bum Choi, Je Kyoun Shin, Hyun Keun Chee, Jun Seok Kim
The Texas Heart Institute Journal
In this study, we retrospectively analyzed the outcomes of adults with bicuspid aortic valve (BAV) disease who underwent aortic valve reconstructive surgery (AVRS), consisting of replacement of the diseased BAV with 2 or 3 pericardial leaflets plus fixation of the sinotubular junction for accurate and constant leaflet coaptation. From December 2007 through April 2013, 135 consecutive patients (mean age, 49.2 ± 13.1 yr; 73.3% men) with symptomatic BAV disease underwent AVRS. Raphe was observed in 84 patients (62.2%), and the remaining 51 patients had pure BAV without raphe. A total of 122 patients (90.4%) underwent 3-leaflet reconstruction, and 13 (9.6%) …

Percutaneous Repair Of Post-Myocardial Infarction Ventricular Septal Defect: Current Approaches And Future Perspectives, Maria D Baldasare, Mark Polyakov, Glenn W Laub, Joseph T Costic, Daniel J Mccormick, Sheldon Goldberg
The Texas Heart Institute Journal
Post-myocardial infarction ventricular septal defect is a devastating complication of ST-elevation myocardial infarction. Although surgical intervention is considered the gold standard for treatment, it carries high morbidity and mortality rates. We present 2 cases that illustrate the application of percutaneous closure of a post-myocardial infarction ventricular septal defect: the first in a patient who had undergone prior surgical closure and then developed a new shunt, and the second as a bridge to definitive surgery in a critically ill patient.
