Constructing Representative Social Networks For Disease Simulation, Tao Yang, Mario Ventresca

The Summer Undergraduate Research Fellowship (SURF) Symposium

Diseases spread mechanisms have been questioned and studied for many years. The ability to make predictions about an epidemic could enable scientists to evaluate inoculation/ isolation plans, control the mortality rate, and prevent the future course of an outbreak. Accurate predictions, however, are extremely hard to make and requires interdisciplinary solutions from epidemiology, sociology, statistics, graph theory, and Computer Science. For making the prediction, currently few network analysis platforms written in C++ are designed and optimized. The research is aimed to address this gap by exploring methods of constructing social contact network, simulating disease spreading, and proposing mitigation strategies for …

Synthesis And Biological Study Of Adenylyl Cyclase Inhibitors, Siyuan Sun, Zhishi Ye, Mingji Dai

The Summer Undergraduate Research Fellowship (SURF) Symposium

Adenylyl cyclases (AC) is a critical family of enzymes which modulates the dynamic cellular level of cAMP, cyclic adenosine monophosphate. The study of cAMP showed that it is indispensable for the signal transduction cascades during many physiological processes, such as immune responses and metabolism which highly relate to cancers. Previous studies of AC inhibitors have been limited due to a lack of isoform-selective small molecule modulators. Selectivity of the molecules is imperative to the activation of only the desired AC inhibitor. The design of the described project was to test the structure activity relationship (SAR) by synthesizing a class of …

Appropriate Development Of The Liver Treg Compartment Is Modulated By The Microbiota And Requires Tgf-Β And Myd88, Ann Maria, Kathryn A. English, James D. Gorham

Dartmouth Scholarship

Neither the early postnatal development of the liver Treg compartment nor the factors that regulate its development has been characterized. We compared the early developmental patterns of Treg cell accumulation in murine liver, thymus, and spleen. A FoxP3EGFP reporter mouse was employed to identify Treg cells. Mononuclear cells were isolated from organs postnatally, stained for CD4, and examined by flow cytometry to enumerate FoxP3+CD4hi cells. To assess roles for TGF-��1, MyD88, and TLR2, gene specific knockout pups were generated from heterozygous breeders. To test the role of commensal bacteria, pregnant dams were administered antibiotics during gestation and after parturition.The pattern …

The Role Of Inflammation In Contrast-Induced Nephropathy, Elijah Kwasa, Sudhir Vinayak, Robert Armstrong

Imaging & Diagnostic Radiology, East Africa

Objective: Global incidence of contrast-induced nephropathy (CIN) is 2-5%, but a recent Kenyan study highlighted a local incidence of 12-14% without offering an explanation for the higher incidence. This study proposes that inflammatory states confer a higher relative risk for development of CIN. Our objective was to determine the risk of developing CIN given the presence of an inflammatory state in patients in Kenya.

Methods: Prospective cohort study of patients undergoing a contrast-enhanced CT (CECT) scan in a private university teaching hospital in Kenya and having no known risk factors for CIN. 423 patients were recruited and grouped into those …

Identification Of Functional Parameters For The Classification Of Older Female Fallers And Prediction Of ‘First-Time’ Fallers, Niklas König Ignasiak

Physical Therapy Faculty Articles and Research

Falls remain a challenge for ageing societies. Strong evidence indicates that a previous fall is the strongest single screening indicator for a subsequent fall and the need for assessing fall risk without accounting for fall history is therefore imperative. Testing in three functional domains (using a total 92 measures) were completed in 84 older women (60–85 years of age), including muscular control, standing balance, and mean and variability of gait. Participants were retrospectively classified as fallers (n = 38) or non-fallers (n = 42) and additionally in a prospective manner to identify first-time fallers (FTFs) (n = 6) within a …

Blau Syndrome, The Prototypic Auto-Inflammatory Granulomatous Disease., Carine H Wouters, Anne Maes, Kevin P Foley, John Bertin, Carlos D Rose

This paper reviews briefly the classical clinical features of the disease, as well as more recently described extra-triad symptoms. From an ongoing prospective multicenter study, we provide new data on the natural history of Blau syndrome, focusing on functional status and visual outcome. We also present an update of the range of different NOD2 mutations found in Blau syndrome as well as recent data on morphologic and immunohistochemical characteristics of the Blau …

Imaging Luciferase-Expressing Viruses, Michael A. Barry, Shannon May, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Optical imaging of luciferage gene expression has become a powerful tool to track cells and viruses in vivo in small animal models. Luciferase imaging has been used to study the location of infection by replication-defective and replication-competent viruses and to track changes in the distribution of viruses in mouse models. This approach has also been used in oncolytic studies as a non-invasive means to monitor the growth and killing of tumor cells modified with luciferase genes. In this chapter, we describe the techniques used for luciferase imaging as have been applied to track replication-defective and replication-competent adenoviruses in mouse and …

Common Genetic Variants In The Hnf1b Gene Contribute To Diabetes And Multiple Cancers, Ke-Sheng Wang, Daniel Owusu, Yue Pan, Chun Xu

Health & Biomedical Sciences Faculty Publications

Diabetes and cancers are major public health problems in the United States and in the world. Epidemiological studies have clearly demonstrated the associations and co morbidity between Type 2 Diabetes (T2D) and multiple cancers such as endometrial and prostate cancers. However, the mechanism of such associations has not been elucidated. Genetic variation is proposed to contribute to these diseases, and common genetic variants may explain part of the associations among these diseases. Single Nucleotide Polymorphisms (SNPs) rs4430796 and rs7501939 within the HNF1B/TCF2 gene (Gene ID: 6928) have been observed to be associated with T2D and endometrial and prostate cancers in …

Clinical And Biochemical Function Of Polymorphic Nr0b1 Ggaa-Microsatellites In Ewing Sarcoma: A Report From The Children's Oncology Group., Michael J. Monument, Kirsten M. Johnson, Elizabeth Mcilvaine, Lisa Abegglen, W. Scott Watkins, Lynn B. Jorde, Richard B. Womer, Natalie Beeler, Laura Monovich, Elizabeth R. Lawlor, Julia A. Bridge, Joshua D. Schiffman, Mark D Krailo, R. Lor Randall, Stephen L. Lessnick

Journal Articles: Pathology and Microbiology

BACKGROUND: The genetics involved in Ewing sarcoma susceptibility and prognosis are poorly understood. EWS/FLI and related EWS/ETS chimeras upregulate numerous gene targets via promoter-based GGAA-microsatellite response elements. These microsatellites are highly polymorphic in humans, and preliminary evidence suggests EWS/FLI-mediated gene expression is highly dependent on the number of GGAA motifs within the microsatellite.

OBJECTIVES: Here we sought to examine the polymorphic spectrum of a GGAA-microsatellite within the NR0B1 promoter (a critical EWS/FLI target) in primary Ewing sarcoma tumors, and characterize how this polymorphism influences gene expression and clinical outcomes.

RESULTS: A complex, bimodal pattern of EWS/FLI-mediated gene expression was observed …

Towards Highly-Integrated Stereovideoscopy For In Vivo Surgical Robots, Jay Carlson

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

When compared to traditional surgery, laparoscopic procedures result in better patient outcomes: shorter recovery, reduced post-operative pain, and less trauma to incisioned tissue. Unfortunately, laparoscopic procedures require specialized training for surgeons, as these minimally-invasive procedures provide an operating environment that has limited dexterity and limited vision. Advanced surgical robotics platforms can make minimally-invasive techniques safer and easier for the surgeon to complete successfully. The most common type of surgical robotics platforms -- the laparoscopic robots -- accomplish this with multi-degree-of-freedom manipulators that are capable of a diversified set of movements when compared to traditional laparoscopic instruments. Also, these laparoscopic robots …

The Effect Of Docosahexaenoic Acid (Dha)-Containing Phosphatidylcholine (Pc) On Liquid-Ordered And Liquid-Disordered Coexistence, Yongwen Gu

Dissertations and Theses

Plasma membranes are essential to both the structure and function of mammalian cells. The first unifying paradigm of membrane structure, the Fluid Mosaic Model, is no longer considered adequate to describe the many non-homogeneous lipid structures that have been observed in both natural and model membranes over the past approximately thirty years. The field of membrane biophysics now appreciates that the complex mixture of different lipid species found in natural membranes produces a range of dynamic, laterally segregated, non-homogeneous structures which exist on time scales ranging from microseconds to minutes.

Palliative Care And Hospice Community Education, Mary Castang

Regis University Student Publications (comprehensive collection)

Executive Summary Palliative Care and Hospice Community Education Problem In the researcher's home hospice practice, a need for community education regarding Palliative Care and Hospice is recognized. Patients and family members need information about End of Life (EOL) care options prior to the urgency of a crisis. According to Szirony, Oopko, Masiulaniec and Binder (2011) many patients and family members learn of hospice and palliative care services only after admission into a program. The decision to sign in to a program reflects their perception of there being no other choice rather than understanding the options and benefits (Szirony, et al, …

Faculty Publications

This book is not just for nurses who care for the dying patient but for all nurses who find themselves at some point in their career feeling burned out, dissatisfied with work life, bullied, or lacking a sense of meaning and purpose in their professional quality of life. Todaro-Franceschi identifies the causes of compassion fatigue and burnout as being multifactorial, yet having a core symptom of the nurse internalizing suffering to the point that it negatively transforms the care a nurse can give. The target audience is wide, with application to current practitioners, students, nurse educators, and anyone working in …

Biphasic Effects Of Fgf2 On Odontoblast Differentiation Involve Changes In The Bmp And Wnt Signaling Pathways, Karen Sagomonyants, Mina Mina

UCHC Articles - Research

Odontoblast differentiation during physiological and reparative dentinogenesis is dependent upon multiple signaling molecules, including Fibroblast Growth Factors (FGFs), Bone Morphogenetic Proteins (BMPs) and Wingless/Integrated (Wnt) ligands. Recent studies in our laboratory showed that continuous exposure of primary dental pulp cultures to FGF2 exerted biphasic effects on the expression of markers of dentinogenesis. In the present study we examined the possible involvement of the BMP and Wnt signaling pathways in mediating the effects of FGF2 on dental pulp cells. Our results showed that stimulatory effects of FGF2 on dentinogenesis during the proliferation phase of growth were associated with increased expression of …

An Investigation Of The Relationship Between Plantar Weight Distribution And The Condition Of Osteoarthritic Knees During Quiet Standing, Brian Joseph Sutterer

Graduate Theses - Biology & Biomedical Engineering

Osteoarthritis (OA) is a damaging disease that commonly affects the knee and can impact function of the lower limb. This study examined how plantar weight distribution is related to the changes in knee alignment and various types of joint damage in patients with OA. A force mat was used to measure plantar weight distribution on 37 patients with knee OA, and the internal condition of the knee was evaluated during surgery. Analysis showed a relationship between medial plantar weight distribution and an increase in knee alignment angle (0.20, p < 0.001). For the damage models, an indirect relationship was found between medial weight distribution and ACL damage (-0.14, p=0.029). No relationship was found for the other types of OA damage. It is reasonable to believe they do exist, however. This study found a connection between weight distribution and alignment, and previous research has shown one between alignment and OA.

Somatic Intronic Microsatellite Loci Differentiate Glioblastoma From Lower-Grade Gliomas, Enusha Karunasena, Lauren J. Mciver, Brian R. Rood, Xiaowei Wu, Hongxiao Zhu, Jasmin H. Bavarva, Harold R. Garner

Pediatrics Faculty Publications

Genomic studies of glioma sub-types have amassed new disease specific mutations, yet these only partially explain how mutations are linked to predisposition or progression. We hypothesized that microsatellite variation could expand the understanding of glioma etiology. Furthermore, germline markers for gliomas are typically undetectable; therefore we also hypothesize that the predictability of cancer-associated microsatellite loci in germline DNA may support the current hypothesis of a glioma cell of origin.

In this study, “normal” germline exome sequenced DNA from the 1000 Genomes Project (n=390) were compared with exome sequences from germlines of subjects with WHO grade II and III lower-grade glioma …
