Gut Feeling: A Holistic Digital Tool For Managing Irritable Bowel Syndrome And Food Sensitivities, Hailey M. Olberding

Honors Program: Senior Projects (Public)

Irritable Bowel Syndrome (IBS) and food intolerances are increasingly prevalent chronic gastrointestinal (GI) conditions that significantly impair quality of life. While the low-Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols (FODMAP) diet has demonstrated success in symptom management, current digital tools fail to offer integrated, user-friendly platforms that holistically track contributing health factors. Gut Feeling is a mobile app (Appendix 1) and complementary website (Appendix 2) developed to fill this gap. By incorporating symptom logging, food intake tracking and complementary database, stress and sleep monitoring, and trend analysis, this platform empowers users to better understand their bodies and manage GI symptoms proactively. …

Effects Of Local Blood Flow On Muscle Stiffness, Megan E. White, Aaron J. Engel, Greg Bashford

UCARE: Research Products

Muscle injuries, in the form of strains or even tears, affect millions of people each year through undue tension on muscles during everyday activities, work tasks, or physical activity including sports or working out. These injuries can take from a few weeks to even months to heal, with patients having to deal with inflammation, swelling, and pain throughout the healing process. Scar tissue also forms when the muscle is injured, which regenerates throughout the healing process, but never fully recovers to its state prior to injury. This scar tissue is thought to make the muscle more prone to subsequent injury, …

A New Method For Shear Wave Speed Estimation In Shear Wave Elastography, Aaron J. Engel, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Visualization of mechanical properties of tissue can aid in noninvasive pathology diagnosis. Shear wave elastography (SWE) measures the elastic properties of soft tissues by estimation of local shear wave propagation speed. In this paper, a new robust method for estimation of shear wave speed is introduced which has the potential for simplifying continuous filtering and real-time elasticity processing. Shear waves were generated by external mechanical excitation and imaged at a high frame rate. Three homogeneous phantoms of varying elastic moduli and one inclusion phantom were imaged. Waves propagating in separate directions were filtered and shear wave speed was estimated by …

Enabling Real-Time Ultrasound Imaging Of Soft Tissue Mechanical Properties By Simplification Of The Shear Wave Motion Equation, Aaron J. Engel, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Ultrasound based shear wave elastography (SWE) is a technique used for non-invasive characterization and imaging of soft tissue mechanical properties. Robust estimation of shear wave propagation speed is essential for imaging of soft tissue mechanical properties. In this study we propose to estimate shear wave speed by inversion of the firstorder wave equation following directional filtering. This approach relies on estimation of first-order derivatives which allows for accurate estimations using smaller smoothing filters than when estimating second-order derivatives. The performance was compared to three current methods used to estimate shear wave propagation speed: direct inversion of the wave equation (DIWE), …

Functional Transcranial Doppler Ultrasound For High Temporal Resolution Measurement Of Lateralization In Visual Memory And Visual Search Cognitive Tasks, B. Hage, M. Alwatban, E. Barney, M. Mills, M. Dodd, E. Truemper, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Functional transcranial Doppler ultrasound (fTCD) is a noninvasive sensing modality that measures blood flow velocities in cerebral arteries (CBFV) with high temporal resolution. Few studies have examined the relationship of CBFV change during visual search and visual memory cognitive tasks. Here a protocol to compare lateralization between these two similar tasks using fTCD is demonstrated. Thirteen healthy volunteers were shown visual scenes on a computer and performed visual search and visual memory tasks while CBFV in the bilateral middle cerebral arteries was monitored with fTCD. Each subject completed 40 trials, consisting of baseline, calibration, instruction, and task periods. Lateralization was …

‘‘We Can Wipe An Entire Culture’’: Fears And Promises Of Dna Biobanking Among Native Americans, Roberto Abadie, Kathleen Heaney

Department of Sociology: Faculty Publications

This paper explores Native American perceptions on DNA biobanking. A qualitative study was conducted among self-declared Native Americans living off reservation in two Midwest cities. Findings demonstrate a paradox: Informants maintain strong hopes for the transformative power of gene-based research while voicing very particular social anxieties. Emerging genomic technologies elicit concerns over the potential for genetic stigmatization or discrimination based on race, preventing access to health insurance or employment. Frequently, social anxieties adopt the narrative form of conspiracy theories which portray powerful agents exploiting or abusing a disenfranchised population. We argue that while Native Americans do not have a monopoly …

Review Of Manon Parry, Broadcasting Birth Control: Mass Media And Family Planning, Rose Holz

Women's and Gender Studies Program: Faculty Publications

As Manon Parry explains in her interesting new book, ‘Many of the women who wrote [to the Birth Control Review] noted that they had read about [Margaret] Sanger’s work in the press, confirming the important role of the mass media in publicizing and building support for the movement’ (p. 13). Therein lies the crux of Parry’s project: the use of publicity was central to the family planning movement and a sustained analysis of its use over time is long overdue. To that end, she challenges several long-standing historiographic assumptions and unearths more than a few fascinating stories. For example, …

Data Mining The Functional Characterizations Of Proteins To Predict Their Cancer-Relatedness, Peter Revesz, Christopher Assi

School of Computing: Faculty Publications

This paper considers two types of protein data. First, data about protein function described in a number of ways, such as, GO terms and PFAM families. Second, data about whether individual proteins are experimentally associated with cancer by an anomalous elevation or lowering of their expressions within cancerous cells. We combine these two types of protein data and test whether the first type of data, that is, the functional descriptors, can predict the second type of data, that is, cancer-relatedness. By using data mining and machine learning, we derive a classifier algorithm that using only GO term and PFAM family …

Data Mining Of Pancreatic Cancer Protein Databases, Peter Revesz, Christopher Assi

School of Computing: Conference and Workshop Papers

Data mining of protein databases poses special challenges because many protein databases are non- relational whereas most data mining and machine learning algorithms assume the input data to be a type of rela- tional database that is also representable as an ARFF file. We developed a method to restructure protein databases so that they become amenable for various data mining and machine learning tools. Our restructuring method en- abled us to apply both decision tree and support vector machine classifiers to a pancreatic protein database. The SVM classifier that used both GO term and PFAM families to characterize proteins gave …

The present invention provides compounds, methods and systems for sequencing nucleic acid using single molecule detection. Using labeled NPs that exhibit charge-switching behavior, single-molecule DNA sequencing in a microchannel sorting system is realized. In operation, sequencing products are detected enabling real-time sequencing as successive detectable moieties flow through a detection channel. By electrically sorting charged molecules, the cleaved product molecules are detected in isolation without interference from unincorporated NPs and without illuminating the polymerase-DNA complex.

Two-Dimensional Blood Flow Velocity Estimation Using Apparent Speckle Pattern Angle Dependence On Scan Velocity, Tiantian Xu, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

An algorithm which measures the lateral component of blood flow velocity was developed in our previous studies based on the increase in speckle size due to relative motion between moving scatterers and spatial rate of scanner A-line acquisition (scan velocity). In this paper, the apparent dominant angle of the speckle pattern in a straight vessel was investigated and a new method of two-dimensional blood flow velocity estimation is introduced. Different scan velocities were used for data acquisition from blood flow traveling at an angle relative to the ultrasound beam. The apparent angle of the speckle pattern changes with different scan …

Monitoring Cerebral Hemodynamics With Transcranial Doppler Ultrasound During Cognitive And Exercise Testing In Adults Following Unilateral Stroke, Brian P. Watt, Judith M. Burnfield, Edward J. Truemper, Thad W. Buster, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

An observational study was performed as a preliminary investigation into the use of transcranial Doppler ultrasound (TCD) for recording cerebral hemodynamic changes during multiple tasks. TCD is a method of measuring cerebral blood flow (CBF) using ultrasound transducers in contact with the surface of the head. Using the maximum flow envelope of the Doppler spectrum returning from the middle cerebral artery (MCA), standard clinical flow indices can be calculated and displayed in real time providing information concerning perturbations in CBF and their potential cause. These indices as well as flow velocity measurements have been recognized as useful in measuring changes …

Trust In Government And Support For Governmental Regulation: The Case Of Electronic Health Records, Mitchel Herian, Nancy C. Shank, Tarik Abdel-Monem

University of Nebraska Public Policy Center: Publications

Background — This paper presents results from a public engagement effort in Nebraska, USA, which measured public opinions about governmental involvement in encouraging the use of electronic health records (EHRs).

Objective — We examine the role of trust in government in contributing to public support for government involvement in the development of EHR technologies. We hypothesize that trust in government will lead to support for federal and state governmental encouragement of the use of EHRs among doctors and insurance companies. Further, because individual experiences with health-care professionals will reduce perceptions of risk, we expect that support for governmental involvement will …

Lateral Blood Flow Velocity Estimation Based On Ultrasound Speckle Size Change With Scan Velocity, Tiantian Xu, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Conventional (Doppler-based) blood flow velocity measurement methods using ultrasound are capable of resolving the axial component (i.e., that aligned with the ultrasound propagation direction) of the blood flow velocity vector. However, these methods are incapable of detecting blood flow in the direction normal to the ultrasound beam. In addition, these methods require repeated pulse-echo interrogation at the same spatial location. A new method has been introduced which estimates the lateral component of blood flow within a single image frame using the observation that the speckle pattern corresponding to blood reflectors (typically red blood cells) stretches (i.e., is smeared) if the …
