Cell-Free Dna Release During Programmed Cell Death In Ischemia Reperfusion Injury, Alexander Dionne, Anthony M. Jevnikar, Zhu-Xu Zhang Jun 2019

Cell-Free Dna Release During Programmed Cell Death In Ischemia Reperfusion Injury, Alexander Dionne, Anthony M. Jevnikar, Zhu-Xu Zhang

Western Research Forum

Transplantation is invariably associated with acute allograft injury caused by ischemia reperfusion injury (IRI). This injury causes cells of the allograft to undergo various forms of programmed cell death including apoptosis and necroptosis. During programmed cell death, immunogenic molecules are released from cells, one of which is cell-free DNA (cfDNA). We hypothesize that cfDNA is released by microvascular endothelial cells (MVECs) during programmed cell death of IRI and that cfDNA acts as both a biomarker for cellular injury as well as a biologically active molecule capable of amplifying inflammation and organ injury.

Our results indicate that cfDNA is released by ...

Proteome Of The Central Apparatus Of A Ciliary Axoneme, Lei Zhao, Yuqing Hou, Tyler Picariello, Branch Craige, George B. Witman Jun 2019

Proteome Of The Central Apparatus Of A Ciliary Axoneme, Lei Zhao, Yuqing Hou, Tyler Picariello, Branch Craige, George B. Witman

Radiology Publications and Presentations

Nearly all motile cilia have a "9+2" axoneme containing a central apparatus (CA), consisting of two central microtubules with projections, that is essential for motility. To date, only 22 proteins are known to be CA components. To identify new candidate CA proteins, we used mass spectrometry to compare axonemes of wild-type Chlamydomonas and a CA-less mutant. We identified 44 novel candidate CA proteins, of which 13 are conserved in humans. Five of the latter were studied more closely, and all five localized to the CA; therefore, most of the other candidates are likely to also be CA components. Our ...

Scintillation Event Localization In Novel Hemi-Ellipsoid Detector For Spect, Hanif R. Soysal May 2019

Scintillation Event Localization In Novel Hemi-Ellipsoid Detector For Spect, Hanif R. Soysal

LSU Master's Theses

A high sensitivity Cardiac SPECT system using hemi-ellipsoid crystals with pinhole collimation was previously proposed by Dey et al. To investigate detector resolution for this design, the scintillation light spread on a monolithic hemi-ellipsoidal CsI crystal was simulated using Geant4 Monte Carlo. The expected distribution of scintillation light on the outer surface of the crystal from photoelectric absorption events was obtained from the simulations for selected points inside the crystal. Two sets of simulations were performed. For the first set, a look-up table (LUT) of 12 points was created and each point mapped to its expected light distribution—four points ...

Open Access Articles

BACKGROUND: Breast cancer is the leading cause of cancer related death in women, with metastasis the principle cause of mortality. New non-invasive prognostic markers are needed for the early detection of metastasis, facilitating treatment decision optimisation. MicroRNA (miRNA) are small, non-coding RNAs regulating gene expression and involved in many cellular processes, including metastasis. As biomarkers, circulating miRNAs (in blood) hold great promise for informing diagnosis or monitoring treatment responses.

METHODS: Plasma extracted RNA from age matched local Luminal A (n = 4) or metastatic disease (n = 4) were profiled using Next Generation Sequencing. Selected differentially expressed miRNA were validated on a ...


Differential Estimation Of Audiograms Using Gaussian Process Active Model Selection, Trevor Larsen May 2019

Differential Estimation Of Audiograms Using Gaussian Process Active Model Selection, Trevor Larsen

Engineering and Applied Science Theses & Dissertations

Classical methods for psychometric function estimation either require excessive resources to perform, as in the method of constants, or produce only a low resolution approximation of the target psychometric function, as in adaptive staircase or up-down procedures. This thesis makes two primary contributions to the estimation of the audiogram, a clinically relevant psychometric function estimated by querying a patient’s for audibility of a collection of tones. First, it covers the implementation of a Gaussian process model for learning an audiogram using another audiogram as a prior belief to speed up the learning procedure. Second, it implements a use case ...


Simulating Alternative Tuberculosis Diagnosis Methods In Underdeveloped Countries, Luke Turner May 2019

Simulating Alternative Tuberculosis Diagnosis Methods In Underdeveloped Countries, Luke Turner

Industrial Engineering Undergraduate Honors Theses

Tuberculosis is the deadliest infectious disease in the world; it is especially rampant in underdeveloped countries because they do not have the infrastructure, technology, or funding to properly combat the infection. However, the development of portable point-of-care diagnosis machines can reverse this epidemic as they far surpass conventional laboratory identification. The question now is where to place these machines, which is a difficult decision with a lack of data. Therefore, a flexible simulation model is created to test the implementation of these machines with different countries and configurations. The simulation tests the baseline model and three proposed implementations of the ...

Seeing Eye To Eye: A Machine Learning Approach To Automated Saccade Analysis, Maigh Attre May 2019

Seeing Eye To Eye: A Machine Learning Approach To Automated Saccade Analysis, Maigh Attre

Honors Scholar Theses

Abnormal ocular motility is a common manifestation of many underlying pathologies particularly those that are neurological. Dynamics of saccades, when the eye rapidly changes its point of fixation, have been characterized for many neurological disorders including concussions, traumatic brain injuries (TBI), and Parkinson’s disease. However, widespread saccade analysis for diagnostic and research purposes requires the recognition of certain eye movement parameters. Key information such as velocity and duration must be determined from data based on a wide set of patients’ characteristics that may range in eye shapes and iris, hair and skin pigmentation [36]. Previous work on saccade analysis ...

Acute Promyelocytic Leukemia: A Case Study Correlating Cytogenetic Abnormality With Prognosis, Alyssa Lamond, Theresa Tellier-Castellone

Senior Honors Projects

Advancements in medical technology today have positively impacted the diagnosis, treatment, and prognosis of cancers. Particularly acute promyelocytic leukemia (APL) has completely improved from having the poorest prognosis to one of the best. Acute promyelocytic leukemia is a malignant disease of hematopoietic tissue classified by WHO as leukemia with >20% blasts from the myeloid lineage, specifically promyelocytes. Determined in 1976, FAB classified AML subtypes M1-M7, with APL being M3. Specific characteristics classify the subtype of AML, with each resulting from a different genetic abnormality. The focus of APL diagnosis, treatment, and prognosis occurs around the known PML-RARα fusion gene. Flow ...

Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin

Electronic Theses and Dissertations

Background. Ethanol (EtOH) consumption is known to affect multiple organs; this is unsurprising, as the concentration of EtOH in the blood at relevant doses reaches the millimolar range. The overarching goal of this dissertation was to elucidate mechanisms of alcohol-induced organ injury, specifically the effects of alcohol on the hepatic extracellular matrix (ECM) proteome, the alcoholic hepatitis (AH) plasma peptidome, and the effects of alcohol on the renal cortex proteome and transcriptome. Methods. Mice were pair-fed ethanol-containing liquid diet chronically, and then some mice were administered lipopolysaccharide (LPS). Liver sections from these mice were processed in a series of increasingly ...


Suffering In Silence: Is Gastroparesis Underdiagnosed?, Dennis J. Baumgardner Apr 2019

Suffering In Silence: Is Gastroparesis Underdiagnosed?, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

In this introduction to Volume 6, Issue 2, the editor-in-chief of the Journal of Patient-Centered Research and Reviews offers additional comment to the clinical review of diabetic gastroparesis authored by Farmer and colleagues (p. 148), regarding the problem of undiagnosed disease. Increased awareness of this entity and appropriate questioning regarding symptoms of diabetic gastroparesis in the primary care setting may prevent the “suffering in silence” experienced by many patients with this complication.

BACKGROUND: Cervical cancer is caused by oncogenic human papillomaviruses (HPV) and is one of the most common malignancies in women living in sub-Saharan Africa. Women infected with the human immunodeficiency virus (HIV) have a higher incidence of cervical cancer, but the full impact on HPV detection is not well understood, and associations of biological and behavioral factors with oncogenic HPV detection have not been fully examined. Therefore, a study was initiated to investigate factors that are associated with oncogenic HPV detection in Kenyan women.

METHODS: Women without cervical dysplasia were enrolled in a longitudinal study. Data from enrollment are presented ...


Synthesis Of A Zn(Ii)-Responsive Paracest Mri Agent For Improved Diagnosis Of Prostate Cancer, Megan Martin, Holly Clancy Apr 2019

Synthesis Of A Zn(Ii)-Responsive Paracest Mri Agent For Improved Diagnosis Of Prostate Cancer, Megan Martin, Holly Clancy

Creative Activity and Research Day - CARD

In the United States, prostate cancer is the leading type of cancer diagnosed in men. Prostate cancer is currently diagnosed with the Prostate-Specific Antigen (PSA) test; however, it leads to many false positives and therefore unneeded biopsies. Previous studies have shown that cancerous prostates have a much lower concentration of zinc than healthy prostates. The goal of this project is to create an MRI contrast agent capable of non-invasively quantifying zinc in the human prostate. Five out of the eight synthetic steps have been successfully completed so far, and the identities of these intermediate products have been verified by 1 ...


Inclusion Body Myositis, Sreelakshmi Panginikkod, Rina Musa Apr 2019

Inclusion Body Myositis, Sreelakshmi Panginikkod, Rina Musa

Open Access Articles

Inclusion body myositis (IBM) is the most common subtype of autoimmune myopathy in patients older than the age of 50 years. Several diagnostic criteria have been proposed for IBM based on expert opinion and consensus groups. Their use in clinical practice is however limited due to low sensitivity. The European Neuromuscular Centre (ENMC) 2011 clinically defined diagnostic criteria have a high specificity of greater than 99% to diagnose IBM, but like other criteria, its sensitivity is low at 57%. ENMC 2011 Inclusion Body Myositis Diagnostic Criteria Mandatory Features: 1. Age of onset later than 45 years. 2. Duration of symptoms ...


Uhthoff Phenomenon, Sreelakshmi Panginikkod, Lokesh A.. Rukmangadachar Apr 2019

Uhthoff Phenomenon, Sreelakshmi Panginikkod, Lokesh A.. Rukmangadachar

Open Access Articles

Uhthoff's phenomenon (also known as Uhthoff sign or Uhthoff syndrome) is described as temporary, short-lived (less than 24 hours) and stereotyped worsening of neurological function among multiple sclerosis patients in response to increases in core body temperature. This phenomenon is named after Wilhelm Uhthoff, a German ophthalmologist who described it. In 1890, Uhthoff first described exercise-induced amblyopia in multiple sclerosis patients. In 1961, this phenomenon was given his surname, Uhthoff's Phenomenon (UP), by G. Ricklefs[1]. In four out of 100 MS patients, Uhthoff observed the appearance of reversible optic symptoms induced by an increase in body temperature ...


Aortoduodenal Fistula Forms From Primary Aortic Stump Graft In A Two-Time Multi-Visceral Transplant Patient With Presentation Of Gastrointestinal Bleed And Bowel Perforation: A Case Report, Brielle Corrente Apr 2019

Aortoduodenal Fistula Forms From Primary Aortic Stump Graft In A Two-Time Multi-Visceral Transplant Patient With Presentation Of Gastrointestinal Bleed And Bowel Perforation: A Case Report, Brielle Corrente

Graduate Student Research Symposium

Usually not diagnosed until open laparotomy, aortoduodenalfistulas (ADF) are one of the rarest complications of intestinal transplant surgery. With an incidence rate of only 0.04% at autopsy and only 250 documented cases since the early 1800’s, aortoduodenal fistulas are the most deadly complications of intestinal transplantation with a mortality rate of 100% without surgical intervention. A 39 year old, two-time multi-visceral transplant African American female patient suffered from a primary aortoduodenal fistula formation in a primary modified multi-visceral transplant aortic stump graft site. With emergency open laparotomy repair, revascularization of the secondary multi-visceral transplant was performed, saving the ...

Assessment Of The Potential Use Of Recombinant Baculovirus-Expressed Lassa Virus Nucleoprotein As A Serodiagnostic Antigen, Sahiba Grover

Kansas State University Undergraduate Research Conference

Lassa virus is an arenavirus causing a disseminated systemic primary viral infection. This virus causes Lassa fever which is a viral hemorrhagic fever endemic in West Africa and is responsible for the deaths of thousands of people each year. There is a possibility for the Lassa virus to be introduced into the US and used as a biological weapon with the potential to harm a large-scale population. Because of increasing international travel, a sizeable burden from the disease, and its potential use for biological warfare, it is necessary to develop sensitive diagnostic assays to accurately detect virus infections and mitigate ...

Two Unique Cases Of X-Linked Scid: A Diagnostic Challenge In The Era Of Newborn Screening, Pooja Purswani, Anne Marie Comeau, Jaime E. Hale, Jolan E. Walter

Open Access Articles

In the era of newborn screening (NBS) for severe combined immunodeficiency (SCID) and the possibility of gene therapy (GT), it is important to link SCID phenotype to the underlying genetic disease. In western countries, X-linked interleukin 2 receptor gamma chain (IL2RG) and adenosine deaminase (ADA) deficiency SCID are two of the most common types of SCID and can be treated by GT. As a challenge, both IL2RG and ADA genes are highly polymorphic and a gene-based diagnosis may be difficult if the variant is of unknown significance or if it is located in non-coding areas of the genes that are ...

Role Of Serum Biomarkers In Early Detection Of Diabetic Cardiomyopathy In The West Virginian Population, Adam Shaver, Alexandra Nichols, Ellen A. Thompson, Amrita Mallick, Nandini Manne, Shanmuga Sundaram, Joseph I. Shapiro Md, Komal Sodhi

Joseph I Shapiro MD

Objectives: Diabetic cardiomyopathy (DCM) is an established complication of diabetes mellitus. In West Virginia, the especially high incidence of diabetes and heart failure validate the necessity of developing new strategies for earlier detection of DCM. Since most DCM patients remain asymptomatic until the later stages of the disease when the fibrotic complications become irreversible, we aimed to explore biomarkers that can identify early-stage DCM.

Methods: The patients were grouped into 4 categories based on clinical diabetic and cardiac parameters: Control, Diabetes (DM), Diastolic dysfunction (DD), and Diabetes with diastolic dysfunction (DM+DD), the last group being the preclinical DCM group ...

Role Of Mucosal Protrusion Angle In Discriminating Between True And False Masses Of The Small Bowel On Video Capsule Endoscopy, May Min, Michael Noujaim, Jonathan Green, Christopher R. Schlieve, Aditya Vaze, Mitchell A. Cahan, David R. Cave

Senior Scholars Program

The diagnosis of small-bowel tumors is challenging due to their low incidence, nonspecific presentation, and limitations of traditional endoscopic techniques. In our study, we examined the utility of the mucosal protrusion angle in differentiating between true submucosal masses and bulges of the small bowel on video capsule endoscopy. We retrospectively reviewed video capsule endoscopies of 34 patients who had suspected small-bowel lesions between 2002 and 2017. Mucosal protrusion angles were defined as the angle between the small-bowel protruding lesion and surrounding mucosa and were measured using a protractor placed on a computer screen. We found that 25 patients were found ...
