Machine Learning Classification Of Traumatic Brain Injury Patients Versus Healthy Controls Using Arterial Spin Labeled Perfusion Mri, Vanessa I. Grass 2021 The Graduate Center, City University of New York

Machine Learning Classification Of Traumatic Brain Injury Patients Versus Healthy Controls Using Arterial Spin Labeled Perfusion Mri, Vanessa I. Grass

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) is one of the most common causes of death and disability worldwide, yet accurate in vivo detection of TBI neuropathology remains challenging due to complexities in the structural and functional changes observed post-injury as well as limitations in conventional neuroimaging modalities. Although advanced neuroimaging techniques such as arterial spin labeling (ASL) can noninvasively assess cerebral blood flow (CBF) changes observed post-injury, this technique is underutilized in TBI research partly due to the low signal-to-noise-ratio (SNR) inherent in ASL imaging. The aim of the current study is to examine the use of machine learning, specifically a Support ...


Impaired 26s Proteasome Assembly Precedes Neuronal Loss In Mutant Ubqln2 Rats., Wenjuan Zhang, Bo Huang, Limo Gao, Cao Huang 2021 Department of Pathology, Anatomy & Cell Biology, Thomas Jefferson University, 1020 Locust Street, Philadelphia, PA 19107, USA

Impaired 26s Proteasome Assembly Precedes Neuronal Loss In Mutant Ubqln2 Rats., Wenjuan Zhang, Bo Huang, Limo Gao, Cao Huang

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Proteasomal dysfunction is known to be associated with amyotrophic lateral sclerosis and frontotemporal degeneration (ALS/FTD). Our previous reports have shown that a mutant form of ubiquilin-2 (UBQLN2) linked to ALS/FTD leads to neurodegeneration accompanied by accumulations of the proteasome subunit Rpt1 in transgenic rats, but the precise pathogenic mechanisms of how this mutation impairs the proteasome remains to be elucidated. Here, we reveal that this UBQLN2 mutation in rats disrupted the proteasome integrity prior to neurodegeneration, that it dissociated the 26S proteasome in vitro, and that its depletion did not affect 26S proteasome assembly. During both disease progression ...

Resident Immune Cells Of The Avascular Lens: Mediators Of The Injury And Fibrotic Response Of The Lens., A. Menko, Jodirae Dedreu, Caitlin M. Logan, Heather Paulson, Alex V Levin, Janice L Walker

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Tissues typically harbor subpopulations of resident immune cells that function as rapid responders to injury and whose activation leads to induction of an adaptive immune response, playing important roles in repair and protection. Since the lens is an avascular tissue, it was presumed that it was absent of resident immune cells. Our studies now show that resident immune cells are a shared feature of the human, mouse, and chicken lens epithelium. These resident immune cells function as immediate responders to injury and rapidly populate the wound edge following mock cataract surgery to function as leader cells. Many of these resident ...


Neurophysiology Of Space Medicine: A Literature Review, Jose R. Velasquez 2021 The University of Texas Rio Grande Valley

Neurophysiology Of Space Medicine: A Literature Review, Jose R. Velasquez

MEDI 9331 Scholarly Activities Clinical Years

Space medicine is becoming an essential and expanding clinical discipline. Acquiring a deeper and complete picture understanding of the multi-systemic response due to space on human health and function is essential to ensure the success of future space exploration. A comprehensive review of the literature was performed using PubMed and focused on the current neurophysiologic findings of the central nervous system’s response to space. Ground-based analogues, which mimic the effects of microgravity, and actual spaceflight studies have been used to analyze these physiologic adaptations to space. Overall, cerebellar, sensorimotor and vestibular brain regions seem to be affected the most ...

Esophageal Cancer Complicated By A Distal Acquired Esophagopulmonary Fistula, Alexander D. Lake, Yousef Almuzaini, Aaron Jaffe, Joseph Staffetti, Mukesh Patel

HCA Healthcare Journal of Medicine

Esophageal respiratory fistulas, commonly found as a tracheoesophageal fistula (TEF), are abnormal connections between the esophagus and trachea. These can be congenital (infants) or acquired (malignancy). A more rare form of an esophageal respiratory fistula is an abnormal connection between the esophagus and the lung parenchyma—also known as an esophagopulmonary fistula. In our case, we present a middle-aged male with a history of esophageal cancer undergoing chemotherapy and radiation presenting into the intensive care unit for increasing shortness of breath and vomiting after eating found to have a rare form of a TEF causing his symptoms.

Highly accurate testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the point of care (POC) is an unmet diagnostic need in emergency care and time-sensitive outpatient care settings. Reverse transcription-PCR (RT-PCR) technology is the gold standard for SARS-CoV-2 diagnostics. We performed a multisite U.S. study comparing the clinical performance of the first U.S. Food and Drug Administration (FDA)-authorized POC RT-PCR for detection of SARS-CoV-2 in 20 min, the cobas Liat SARS-CoV-2 and influenza A/B nucleic acid test, to the most widely used RT-PCR laboratory test, the cobas 68/8800 SARS-CoV-2 test.

Journal Articles: Genetics, Cell Biology & Anatomy

BACKGROUND: Single-cell sequencing enables us to better understand genetic diseases, such as cancer or autoimmune disorders, which are often affected by changes in rare cells. Currently, no existing software is aimed at identifying single nucleotide variations or micro (1-50 bp) insertions and deletions in single-cell RNA sequencing (scRNA-seq) data. Generating high-quality variant data is vital to the study of the aforementioned diseases, among others.

RESULTS: In this study, we report the design and implementation of Red Panda, a novel method to accurately identify variants in scRNA-seq data. Variants were called on scRNA-seq data from human articular chondrocytes, mouse embryonic fibroblasts ...


Steered Molecular Dynamic Simulations Reveal Marfan Syndrome Mutations Disrupt Fibrillin-1 Cbegf Domain Mechanosensitive Balcium Binding, Stephen J. Haller, Adrian E. Roitberg, Andrew T. Dudley 2020 University of Nebraska Medical Center

Steered Molecular Dynamic Simulations Reveal Marfan Syndrome Mutations Disrupt Fibrillin-1 Cbegf Domain Mechanosensitive Balcium Binding, Stephen J. Haller, Adrian E. Roitberg, Andrew T. Dudley

Journal Articles: Genetics, Cell Biology & Anatomy

Marfan syndrome (MFS) is a highly variable genetic connective tissue disorder caused by mutations in the calcium binding extracellular matrix glycoprotein fibrillin-1. Patients with the most severe form of MFS (neonatal MFS; nMFS) tend to have mutations that cluster in an internal region of fibrillin-1 called the neonatal region. This region is predominantly composed of eight calcium-binding epidermal growth factor-like (cbEGF) domains, each of which binds one calcium ion and is stabilized by three highly conserved disulfide bonds. Crucially, calcium plays a fundamental role in stabilizing cbEGF domains. Perturbed calcium binding caused by cbEGF domain mutations is thus thought to ...

Exosomes Secreted Under Hypoxia Enhance Stemness In Ewing's Sarcoma Through Mir-210 Delivery, Matthew J. Kling, Nagendra K. Chaturvedi, Varun Kesherwani, Don W. Coulter, Timothy R. Mcguire, J. Graham Sharp, Shantaram S. Joshi

Journal Articles: Genetics, Cell Biology & Anatomy

Intercellular communication between tumor cells within the hypoxic microenvironment promote aggressiveness and poor patient prognoses for reasons that remain unclear. Here we show that hypoxic Ewing's sarcoma (EWS) cells release exosomes that promote sphere formation, a stem-like phenotype, in EWS cells by enhancing survival. Analysis of the hypoxic exosomal miRNA cargo identified a HIF-1α regulated miRNA, miR-210, as a potential mediator of sphere formation in cells exposed to hypoxic exosomes. Knockdown of HIF-1α in hypoxic EWS cells led to decreased exosomal miR-210 levels and reduced the capacity of hypoxic exosomes to form spheres. Inhibition of miR-210 in hypoxic spheres ...

A Fatal Rectus Sheath Hematoma After A Myasthenia Crisis Case Report, Robert G. Michaud, Lesley B. Gordon 2020 Tufts University School of Medicine - Maine Track Program

A Fatal Rectus Sheath Hematoma After A Myasthenia Crisis Case Report, Robert G. Michaud, Lesley B. Gordon

Journal of Maine Medical Center

Introduction: Rectus sheath hematomas (RSH) generally occur due to damage to the inferior epigastric artery. They are rare causes of abdominal pain or acute blood loss anemia, but are an important diagnostic consideration because they can be cryptic and are potentially fatal.

Clinical Findings: An 85-year-old female who had been admitted to the hospital for 10 days with a myasthenia crisis was found to be abruptly hypotensive with a tender abdominal mass in the left lower quadrant subtly crossing midline. She was on prophylactic anticoagulation during her hospitalization.

Main diagnosis, therapeutics, interventions, and outcomes: The patient was initially stabilized with ...

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Genes that establish the circadian clock have differential expression with respect to solar time in central and peripheral tissues. Here, we find circadian-time-induced differential expression in a large number of genes not associated with circadian rhythms in two brain regions lacking overt circadian function: the dorsal vagal complex (DVC) and the central nucleus of the amygdala (CeA). These regions primarily engage in autonomic, homeostatic, and emotional regulation. However, we find striking diurnal shifts in gene expression in these regions of male Sprague Dawley rats with no obvious patterns that could be attributed to function or region. These findings have implications ...

Sleep-Wake Disturbances In Mild Traumatic Brain Injury: Meta Analysis Of Literature And Modeling Of Cerebral Tissue Vulnerability, Xiangfu Zhang, Subhendra Sarkar, Mary A. Browne

Publications and Research

Sleep disturbance is a frequent complaint for patients with mild traumatic brain injury (mTBI), it can prolong recovery, and the oxidative stress from lack of sleep could worsen other secondary damages of mTBI. The common types of sleep disturbance of mTBI include insomnia, daytime sleepiness, and obstructive sleep apnea. Conventional imaging often fails to detect any abnormalities in mTBI, and the etiology of sleep disturbance is still unclear. Based on the analysis of current published neurobiological and imaging literature, multiple factors could play a role leading to sleep disturbance in mTBI, however, we have focused on the diencephalon, melatonin and ...


The Quantified Elf, Umico Niwa 2020 Virginia Commonwealth University

The Quantified Elf, Umico Niwa

Theses and Dissertations

The Quantified Elf is an ongoing collection of scientific, medical, archaeological articles and excerpts from my personal journal. It is a way by which I explore the various ways Western notions of personhood subsume human life into constructs of sexuality and gender, overlooking the various other modes of unbridled existence: plant, microbial. fungal, animal, celestial bodies. The speculative medical papers propose novel forms of body modification to combat gender dysphoria.

Long Non-Coding Rna Profiling Of Pediatric Medulloblastoma, Varun Kesherwani, Mamta Shukla, Don W. Coulter, J. Graham Sharp, Shantaram Joshi, Nagendra K. Chaturvedi

Journal Articles: Genetics, Cell Biology & Anatomy

BACKGROUND: Medulloblastoma (MB) is one of the most common malignant cancers in children. MB is primarily classified into four subgroups based on molecular and clinical characteristics as (1) WNT (2) Sonic-hedgehog (SHH) (3) Group 3 (4) Group 4. Molecular characteristics used for MB classification are based on genomic and mRNAs profiles. MB subgroups share genomic and mRNA profiles and require multiple molecular markers for differentiation from each other. Long non-coding RNAs (lncRNAs) are more than 200 nucleotide long RNAs and primarily involve in gene regulation at epigenetic and post-transcriptional levels. LncRNAs have been recognized as diagnostic and prognostic markers in ...

Undergraduate Arts and Research Showcase

Biology is unique from other science disciplines in that concepts taught in core classes can inform our student’s understanding of sex and gender. A biology major encounters lessons on sex determination, sexual reproduction, and sex characteristics in their courses. The language used in these units matters. It is imperative that educators consider how the language, examples, and content that we use in classrooms drive (or not) inclusivity for gender- and sexuality-diverse (GSD) (aka LGBTQ+) individuals. We chose to analyze four college-level human anatomy/physiology (AP) textbooks for GSD population inclusivity. We adopted a queer theory framework to critically examine ...

Corpus Cavernosum Abscess Secondary To Traumatic Perforation Of Urethral Diverticulum, Thomas C. Gore, Anna Schepcoff, Domenick Sorresso

West Florida Division Virtual Research Day

A corpus cavernosum abscess is a rare condition. Usual etiologies include penile injection of erectile dysfunction medications or illicit drugs, priapism, sexually transmitted infections, and trauma; however, there have been reported cases of idiopathic etiology. The most common causative organisms include Staphylococcus aureus, Streptococci, and Bacteroides [1]. Diagnosis is typically made clinically and through imaging (computed tomography [CT] and ultrasound). The first-line treatment is the use of intravenous (IV) antibiotics and surgical drainage. More conservative treatment, however, includes aspiration in conjunction with IV antibiotics [2-3]. Urethral diverticulum (UD) is the formation of a saccular outpouching of the urethral lumen. Symptoms ...

Capstone Showcase

ABSTRACT

Introduction: Anterior Cruciate Ligament (ACL) injuries are an upsetting setback for many athletes that require a long and costly recovery process. The injury rates are four times greater in women than men. Preventative measures that help to prevent ACL injuries are limited to stretching and strengthening. Therefore, this review aims to investigate if oral contraceptive [I] usage provides a possible new avenue for prevention of ACL injury [O] in young female athletes (ages 18-30) [P] compared to those that do not take oral contraceptives [C].

Methods: A literature review was performed though PubMed, Google Scholar, SCOPUS Database, and ClinicalKey ...
