A Nonrigid Registration Method For Correcting Brain Deformation Induced By Tumor Resection, Yixun Liu, Chengjun Yao, Fotis Drakopoulos, Jinsong Wu, Liangfu Zhou, Nikos Chrisochoides

Computer Science Faculty Publications

Purpose: This paper presents a nonrigid registration method to align preoperative MRI with intraoperative MRI to compensate for brain deformation during tumor resection. This method extends traditional point-based nonrigid registration in two aspects: (1) allow the input data to be incomplete and (2) simulate the underlying deformation with a heterogeneous biomechanical model.

Methods: The method formulates the registration as a three-variable (point correspondence, deformation field, and resection region) functional minimization problem, in which point correspondence is represented by a fuzzy assign matrix; Deformation field is represented by a piecewise linear function regularized by the strain energy of a heterogeneous biomechanical …

Hypothesis Testing In Normal Admixture Models To Detect Heterogeneous Genetic Signals, Qian Fan, Richard Charnigo, Zohreh Talebizadeh, Hongying Dai

Manuscripts, Articles, Book Chapters and Other Papers

In this work we consider a three-component normal mixture model in which one component is known to have mean zero and the other two contaminating components have a nonnegative and a nonpositive mean respectively, while all three components share a common unknown variance parameter. One potential application of this model may be in prioritizing statistical scores obtained in biological experiments, including genetics data. Such a mixture model may be useful in describing the distribution of numerous Z test statistics corresponding to different genes or SNPs, such that a “significant” Z test statistic for a particular gene suggests its connection to …

Glutaredoxin-2 (Grx2) modulates the activity of several mitochondrial proteins in cardiac tissue by catalyzing deglutathionylation reactions. However, it remains uncertain whether Grx2 is required to control mitochondrial ATP output in heart. Here, we report that Grx2 plays a vital role modulating mitochondrial energetics and heart physiology by mediating the deglutathionylation of mitochondrial proteins. Deletion of Grx2 (Grx2−/−) decreased ATP production by complex I-linked substrates to half that in wild type (WT) mitochondria. Decreased respiration was associated with increased complex I glutathionylation diminishing its activity. Tissue glucose uptake was concomitantly increased. Mitochondrial ATP output and complex I activity could be recovered …

Background: Elevated levels of CRP have been shown to be associated with an increase in risk of cardiovascular disease (CVD). Studies analyzing the relationship between physical activity (PA) and CRP by gender have produced mixed results.

Methods: The sample (n=9,135) included participants in the 1999-2004 National Health and Nutrition Examination Survey (NHANES). Three categories of reported MSA participation were created: no MSA (referent group), some MSA (≥1 to/wk), and meeting the …


Nonnutritive Sweetener And Weight Management: A Potential Paradox In Modern Dieting, Katharine Mary Wright Jan 2014

Nonnutritive Sweetener And Weight Management: A Potential Paradox In Modern Dieting, Katharine Mary Wright

UNF Graduate Theses and Dissertations

Obesity is a serious health concern in modern society. One way to reduce caloric intake is with nonnutritive sweeteners (NNS). However, recent research suggests they may be compounding the obesity problem. Nonnutritive sweeteners have been linked to increased body mass in a few studies and may be a barrier to effective weight management for some individuals.

Under the framework of the health belief model, the research question was: Does this pattern of NNS-BMI covariance exist in young adults at the University of North Florida and, if so, are there other dietary or activity differences that might partially explain this relationship? …

Prevalence And Prevention Of The Female Athlete Triad, Elizabeth Dachenhaus

Honors Projects

A study was composed to analyze the three components of the female athlete triad: disordered eating, amenorrhea, and osteoporosis. The cyclic behavior of these three components and determination of which of the pillars of the triad is the most dangerous was also focused on. In order to test the prevalence of disordered eating among women’s collegiate teams, a brief survey was distributed and analyzed among athletes at Bowling Green State University. In addition to confirming that women in aesthetic sports experience a greater amount of disordered eating on the team, the survey also identified women that participated in sports perceived …


The Toxoplasma Gondii Cyst Wall Protein Cst1 Is Critical For Cyst Wall Integrity And Promotes Bradyzoite Persistence, Tadakimi Tomita, David J. Bzik, Yan Fen Ma, Barbara A. Fox Dec 2013

The Toxoplasma Gondii Cyst Wall Protein Cst1 Is Critical For Cyst Wall Integrity And Promotes Bradyzoite Persistence, Tadakimi Tomita, David J. Bzik, Yan Fen Ma, Barbara A. Fox

Dartmouth Scholarship

Toxoplasma gondii infects up to one third of the world's population. A key to the success of T. gondii as a parasite is its ability to persist for the life of its host as bradyzoites within tissue cysts. The glycosylated cyst wall is the key structural feature that facilitates persistence and oral transmission of this parasite. Because most of the antibodies and reagents that recognize the cyst wall recognize carbohydrates, identification of the components of the cyst wall has been technically challenging. We have identified CST1 (TGME49_064660) as a 250 kDa SRS (SAG1 related sequence) domain protein with a large …


A Mechanism Linking Id2-Tgfβ Crosstalk To Reversible Adaptive Plasticity In Neuroblastoma, Lina Chakrabarti, Bi-Dar Wang, Norman H. Lee, Anthony D. Sandler Dec 2013

A Mechanism Linking Id2-Tgfβ Crosstalk To Reversible Adaptive Plasticity In Neuroblastoma, Lina Chakrabarti, Bi-Dar Wang, Norman H. Lee, Anthony D. Sandler

Pharmacology and Physiology Faculty Publications

The ability of high-risk neuroblastoma to survive unfavorable growth conditions and multimodal therapy has produced an elusive childhood cancer with remarkably poor prognosis. A novel phenomenon enabling neuroblastoma to survive selection pressure is its capacity for reversible adaptive plasticity. This plasticity allows cells to transition between highly proliferative anchorage dependent (AD) and slow growing, anoikis-resistant anchorage independent (AI) phenotypes. Both phenotypes are present in established mouse and human tumors. The differential gene expression profile of the two cellular phenotypes in the mouse Neuro2a cell line delineated pathways of proliferation in AD cells or tyrosine kinase activation/ apoptosis inhibition in AI …

Licht, Anne-Sophie Dugast, Todd Suscovich, Ickwon Choi, Chris Bailey-Kellogg, Galit Alter, Margaret E. Ackerman Dec 2013

Divergent Antibody Subclass And Specificity Profiles But Not Protective Hla-B Alleles Are Associated With Variable Antibody Effector Function Among Hiv-1 Controllers, Jennifer I. Lai, Anna F. Licht, Anne-Sophie Dugast, Todd Suscovich, Ickwon Choi, Chris Bailey-Kellogg, Galit Alter, Margaret E. Ackerman

Dartmouth Scholarship

Understanding the coordination between humoral and cellular immune responses may be the key to developing protective vaccines, and because genetic studies of long-term HIV-1 nonprogressors have associated specific HLA-B alleles with spontaneous control of viral replication, this subject group presents an opportunity to investigate relationships between arms of the adaptive immune system. Given evidence suggesting that cellular immunity may play a role in viral suppression, we sought to determine whether and how the humoral immune response might vary among controllers. Significantly, Fc-mediated antibody effector functions have likewise been associated with durable viral control. In this study, we compared the effector …


Impact Of Oxidative Stress On Female Fertility., Tasha Harris Dec 2013

Impact Of Oxidative Stress On Female Fertility., Tasha Harris

Undergraduate Honors Theses

This study examined nutritional status and fecundity of women and was approved for patient enrollment by the ETSU Institutional Review Board (IRB). Once enrolled, participants filled out two food frequency questionnaires (FFQ, fruit/vegetable intake, fat intake), self-reported anthropometric data, and had one 5 mL vacutainer of whole blood (EDTA) collected for measures of oxidative stress (OS), coenzyme Q10 level, and fatty acid profile of the red blood cell (RBC) membrane. Participants were either designated to the case group (13 women experiencing fertility problems and an anti-mullerian hormone level of 1 ng/ml or less (AMH, <1 ng/mL)) or the control group (13 women experiencing normal ovulation cycles and no evidence of polycystic disease). This study hypothesized that the case group would have poorer plasma antioxidant status, consume more dietary saturated fat and have lower levels of omega-3 and higher levels of omega-6 fatty acids in the RBC membrane. Results showed that case participants had significantly higher body mass index (BMI) when graduating from high school, BMI upon enrollment in the study, and trended to gain more weight since high school. Antioxidant status of the plasma tended to be higher for the case group. This result was surprising as case participants consumed significantly fewer servings of fruits and vegetables (sources of antioxidants) than control subjects. FFQ results indicated that case participants consumed significantly higher amounts of total fat (g), saturated fat (g), unsaturated fat (g), and their diets had a higher dietary fat percent. No significant differences were noted in the individual fatty acids isolated from the RBC membrane or in calculated ratios of fatty acid between case and control groups. The fatty acid profile from RBC membranes are in agreement with self-reported fat intake from FFQ data and may provide a rationale for no differences observed between the two groups.


Biochemical Assay Optimization And Computational Screening Efforts To Identify Potential Luxs Inhibitors, Keeshia Q. Wang Dec 2013

Biochemical Assay Optimization And Computational Screening Efforts To Identify Potential Luxs Inhibitors, Keeshia Q. Wang

Master's Theses

Quorum sensing (QS) is a process of coordination of bacterial gene expression in response to cell population. System two QS is regulated by the small signaling molecule autoinducer-2 (AI-2) and is implicated in the infectious behaviors of various bacterial species. AI-2 is biosynthesized from S-ribosylhomocysteine (SRH) by the enzyme LuxS and induces interspecies cell-to-cell communication. Inhibition of LuxS would therefore inhibit interspecies QS. Herein, a search for novel molecular species that will competitively bind with SRH in the LuxS binding site is performed in silico. Computational screening results are then validated in vitro using an optimized LuxS inhibition …


Impact Of Noise On Molecular Network Inference, Radhakrishnan Nagarajan, Marco Scutari Dec 2013

Impact Of Noise On Molecular Network Inference, Radhakrishnan Nagarajan, Marco Scutari

Biostatistics Faculty Publications

Molecular entities work in concert as a system and mediate phenotypic outcomes and disease states. There has been recent interest in modelling the associations between molecular entities from their observed expression profiles as networks using a battery of algorithms. These networks have proven to be useful abstractions of the underlying pathways and signalling mechanisms. Noise is ubiquitous in molecular data and can have a pronounced effect on the inferred network. Noise can be an outcome of several factors including: inherent stochastic mechanisms at the molecular level, variation in the abundance of molecules, heterogeneity, sensitivity of the biological assay or measurement …

Surface-Enhanced Raman Spectroscopy (Sers) Tracking Of Chelerythrine, A Na+ K+ Pump Inhibitor, Into Cytosol And Plasma Membrane Fractions Of Human Lens Epithelial Cell Cultures, Kevin M. Dorney, Ioana E.P. Sizemore, Tariq Alqahtani, Norma C. Adragna, Peter K. Lauf

Pharmacology and Toxicology Faculty Publications

Background/aims: The quaternary benzo-phenanthridine alkaloid (QBA) chelerythrine (CET) is a pro-apoptotic drug and Na(+)/K(+) pump (NKP) inhibitor in human lens epithelial cells (HLECs). In order to obtain further insight into the mechanism of NKP inhibition by CET, its sub-cellular distribution was quantified in cytosolic and membrane fractions of HLEC cultures by surface-enhanced Raman spectroscopy (SERS). Methods: Silver nanoparticles (AgNPs) prepared by the Creighton method were concentrated, and size-selected using a one-step tangential flow filtration approach. HLECs cultures were exposed to 50 μM CET in 300 mOsM phosphate-buffered NaCl for 30 min. A variety of cytosolic extracts, crude and purified membranes, …


Enhanced Pancreatic Beta-Cells Proliferation And Functionality, Hanan Abdulaziz Alismail Dec 2013

Enhanced Pancreatic Beta-Cells Proliferation And Functionality, Hanan Abdulaziz Alismail

Graduate Theses and Dissertations

Biologically functional beta-cells proliferate at an extremely low rate with limited turnover capacity. This cellular property hinders cell-based therapy for clinical applications. Many attempts have been made to develop techniques that allow large quantities of production of clinically relevant islet β-cells in vitro. A line of studies demonstrates that functional beta-cells can proliferate under certain circumstances, providing hope for generating and expanding these cells in vitro and transplanting them into the recipient. In this study, we showed that a membrane substrate offers a better niche for beta cell proliferation and insulin secretion. Mouse beta cells were grown on a tissue …

Intrahypothalamic Pituitary Adenylate Cyclase-Activating Polypeptide Regulates Energy Balance Via Site-Specific Actions On Feeding And Metabolism, Jon Resch, Brian Maunze, Adriana K. Gerhardt, Samuel K. Magnuson, Kailynn A. Phillips, Sujean Choi

Biomedical Sciences Faculty Research and Publications

Numerous studies have demonstrated that both the hypothalamic paraventricular nuclei (PVN) and ventromedial nuclei (VMN) regulate energy homeostasis through behavioral and metabolic mechanisms. Receptors for pituitary adenylate cyclase-activating polypeptide (PACAP) are abundantly expressed in these nuclei suggesting PACAP may be critical for the regulation of feeding behavior and body weight. To characterize the unique behavioral and physiological responses attributed to select hypothalamic cell groups, PACAP was site-specifically injected into the PVN or VMN. Overall food intake was significantly reduced by PACAP at both sites, however meal pattern analysis revealed only injections into the PVN produced significant reductions in meal size, …

Staphylococcus Aureus Sara Regulates Inflammation And Colonization During Central Nervous System Biofilm Formation, Jessica N. Snowden, Matthew K. Beaver, Karen Beenken, Alexander R. Horswill, Tammy L. Kielian

Journal Articles: Pediatrics

Infection is a frequent and serious complication following the treatment of hydrocephalus with CSF shunts, with limited therapeutic options because of biofilm formation along the catheter surface. Here we evaluated the possibility that the sarA regulatory locus engenders S. aureus more resistant to immune recognition in the central nervous system (CNS) based on its reported ability to regulate biofilm formation. We utilized our established model of CNS catheter-associated infection, similar to CSF shunt infections seen in humans, to compare the kinetics of bacterial titers, cytokine production and inflammatory cell influx elicited by wild type S. aureus versus an isogenic sarA …

Seventy percent of patient care is based on decisions made from laboratory results, yet there is a growing shortage of medical technologists. Although some baby boomers are delaying retirement, worsening of the shortage crisis is inevitable. Retention of medical technologists has become more important than recruitment. The purpose of this study was to identify and evaluate innovative retention strategies used by clinical laboratory managers throughout the United States.

A significant finding of this study was the lack of qualified medical technologists entering the ranks of laboratory managers. This study identified …


Scanned Ion Beam Therapy For Thoracic Tumors, John Gordon Eley Dec 2013

Scanned Ion Beam Therapy For Thoracic Tumors, John Gordon Eley

Dissertations and Theses (Open Access)

Although frequently cured of Hodgkin lymphoma, adolescents and young adults can develop radiation induced second cancers. These patients could potentially benefit from scanned ion radiotherapy yet likely would require motion mitigation strategies. In theory, four-dimensional (4D) optimization of ion beam fields for individual motion states of respiration can enable superior sparing of healthy tissue near moving targets, compared to other motion mitigation strategies. Furthermore, carbon-ion therapy can sometimes provide greater relative biological effectiveness (RBE) for cell sterilization in a target but nearly equivalent RBE in tissue upstream of the target, compared to proton therapy. Thus, we expected that for some …

Erg11-Mediated Azole Resistance In Candida Albicans, Stephanie Ann Flowers Dec 2013

Erg11-Mediated Azole Resistance In Candida Albicans, Stephanie Ann Flowers

Theses and Dissertations (ETD)

Although many medically important Candida species are commensal to the gut or colonizers of the skin, these organisms have the propensity to cause disease in the event of a waning immune system. Clinical manifestations of infections with Candida species can range from superficial mucosal infections to deep organ involvement usually resulting from haematogenous spread of infection. Despite significant progress made in the management of patients with fungal infections, the emergence of antifungal resistant clinical isolates creates significant problem in regards to antifungal prophylaxis and empirical treatment strategies. Antifungal resistance is associated with high mortality rates and hefty medical costs. The …
