We describe a recently recognized disease entity, limbic-predominant age-related TDP-43 encephalopathy (LATE). LATE neuropathological change (LATE-NC) is defined by a stereotypical TDP-43 proteinopathy in older adults, with or without coexisting hippocampal sclerosis pathology. LATE-NC is a common TDP-43 proteinopathy, associated with an amnestic dementia syndrome that mimicked Alzheimer’s-type dementia in retrospective autopsy studies. LATE is distinguished from frontotemporal lobar degeneration with TDP-43 pathology based on its epidemiology (LATE generally affects older subjects), and relatively restricted neuroanatomical distribution of TDP-43 proteinopathy. In community-based autopsy cohorts, ∼25% of brains had sufficient burden of LATE-NC to be associated with discernible cognitive impairment ...


The Generation Of Novel Metal-Folate- Phenanthroline Complexes And Phenanthroline-Folate Conjugates With Potential As Chemotherapeutic Agents, Aisling Crowley [Thesis] 2019 Technological University Dublin

The Generation Of Novel Metal-Folate- Phenanthroline Complexes And Phenanthroline-Folate Conjugates With Potential As Chemotherapeutic Agents, Aisling Crowley [Thesis]

Doctoral

The folate receptor (FR) was identified in 1986 and has been established as a ‘molecular Trojan Horse’ target for the uptake of folate-conjugated organic molecules into cells. The FR is overexpressed in many malignancies, including those of the ovary, uterus, breast, cervix, and prostate, yet it is reportedly under-expressed in normal healthy cells. This difference in expression and the high affinity/specificity of folate towards the folate receptor presents a promising drug delivery system. The aim of this research was to utilise folic acid as a targeting moiety and generate simple metal folate and novel folate-phenanthroline complexes with cytotoxic properties ...


Selenomethionine Protects Mutant Tau N27a Cell From Oxidative Stress And Decreases Phosphorylation Of Tau, Madelin LoCicero 2019 Augustana College, Rock Island Illinois

Selenomethionine Protects Mutant Tau N27a Cell From Oxidative Stress And Decreases Phosphorylation Of Tau, Madelin Locicero

Celebration of Learning

Alzheimer’s Disease (AD) is neurodegenerative disease characterized by loss of cells and aggregated tau in the hippocampus. Hyperphosphorylated tau causes the misfolding of tau proteins (aggregated tau), which are responsible for proper neuronal activity. Selenium-methionine has been known to decrease the amount of phosphorylated tau within mutant and wild type 3xTg- AD mice. However, selenium can be toxic to cell depending on the type of cells and the concentration of selenium. The purpose of this study is to determine the effect selenium-methionine has on decreasing hyperphosphorylation of tau, protecting cells from oxidative stress, and decreasing the amount of aggregated ...


A Multimodal Approach To Investigate Brain Reorganization After Spinal Cord Injury Using Functional Magnetic Resonance Imaging And Functional Near-Infrared Spectroscopy, Keerthana Deepti Karunakaran 2019 New Jersey Institute of Technology

A Multimodal Approach To Investigate Brain Reorganization After Spinal Cord Injury Using Functional Magnetic Resonance Imaging And Functional Near-Infrared Spectroscopy, Keerthana Deepti Karunakaran

Dissertations

Traumatic Spinal Cord Injury (SCI) results in structural and functional neurological changes at both the brain and the level of the spinal cord. Anatomical studies indicate decreased grey matter volume in sensorimotor and non-sensorimotor regions of the cortex following SCI; whereas, neurophysiological findings mostly report altered functional activity in the sensorimotor nodes of the cortex, subcortex, and cerebellum. Therefore, it is currently unknown whether tissue atrophy observed in non-motor related areas has any concomitant functional consequences. Furthermore, the neural underpinnings of adaptive neuroplasticity after SCI is not well-defined in the current literature. Hence, this dissertation is a pioneer study investigating ...


High-Performance Learning Systems Using Low-Precision Nanoscale Devices, Nandakumar Sasidharan Rajalekshmi 2019 New Jersey Institute of Technology

High-Performance Learning Systems Using Low-Precision Nanoscale Devices, Nandakumar Sasidharan Rajalekshmi

Dissertations

Brain-inspired computation promises a paradigm shift in information processing, both in terms of its parallel processing architecture and the ability to learn to tackle problems deemed unsolvable by traditional algorithmic approaches. The computational capability of the human brain is believed to stem from an interconnected network of 100 billion compute nodes (neurons) that interact with each other through approximately 1015 adjustable memory junctions (synapses). The conductance of synapses is modifiable allowing the network to learn and perform various cognitive functions. Artificial neural networks inspired by this architecture have demonstrated even super-human performance in many complex tasks.

Computational systems based ...


Technical Freediving: An Emerging Breath-Hold Diving Technique, Derek Covington, Robert H. Lee, Steven Toffel, Alberto Bursian, Kirk Krack, Chris Giordano 2019 University of Florida

Technical Freediving: An Emerging Breath-Hold Diving Technique, Derek Covington, Robert H. Lee, Steven Toffel, Alberto Bursian, Kirk Krack, Chris Giordano

Journal of Human Performance in Extreme Environments

Technical freediving can be defined as freediving augmented by the use of oxygen-enriched gases or oxygen before, during, or after a freedive. As a result of these techniques, breath-hold divers can visit and enjoy underwater wrecks, reefs, and other diving locations previously located at depths unreachable to apnea divers. By pre-breathing oxygen-enriched gases in conjunction with hyperventilation—which decreases the partial pressure of carbon dioxide (PCO2)—the technical freediver now has additional oxygen to facilitate aerobic respiration during the dive. In addition, pre-breathing oxygen decreases tissue nitrogen tensions, which limits inert gas loading and decreases the risk of decompression sickness ...


Control Of Antiviral Innate Immune Response By Protein Geranylgeranylation, Shigao Yang, Zhaozhao Jiang, Katherine A. Fitzgerald, Donghai Wang 2019 Duke University

Control Of Antiviral Innate Immune Response By Protein Geranylgeranylation, Shigao Yang, Zhaozhao Jiang, Katherine A. Fitzgerald, Donghai Wang

Open Access Articles

The mitochondrial antiviral signaling protein (MAVS) orchestrates host antiviral innate immune response to RNA virus infection. However, how MAVS signaling is controlled to eradicate virus while preventing self-destructive inflammation remains obscure. Here, we show that protein geranylgeranylation, a posttranslational lipid modification of proteins, limits MAVS-mediated immune signaling by targeting Rho family small guanosine triphosphatase Rac1 into the mitochondria-associated endoplasmic reticulum (ER) membranes (MAMs) at the mitochondria-ER junction. Protein geranylgeranylation and subsequent palmitoylation promote Rac1 translocation into MAMs upon viral infection. MAM-localized Rac1 limits MAVS' interaction with E3 ligase Trim31 and hence inhibits MAVS ubiquitination, aggregation, and activation. Rac1 also facilitates ...

Sugars and refined carbohydrates are major components of the modern diet. ATP-citrate lyase (ACLY) is upregulated in adipocytes in response to carbohydrate consumption and generates acetyl-coenzyme A (CoA) for both lipid synthesis and acetylation reactions. Here, we investigate the role of ACLY in the metabolic and transcriptional responses to carbohydrates in adipocytes and unexpectedly uncover a sexually dimorphic function in maintaining systemic metabolic homeostasis. When fed a high-sucrose diet, Acly(FAT-/-) females exhibit a lipodystrophy-like phenotype, with minimal fat accumulation, insulin resistance, and hepatic lipid accumulation, whereas Acly(FAT-/-) males have only mild metabolic phenotypes. We find that ACLY is ...


Scintillation Event Localization In Novel Hemi-Ellipsoid Detector For Spect, Hanif R. Soysal 2019 Louisiana State University and Agricultural and Mechanical College

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 ...

Novel Amphiphilic Cyclobutene And Cyclobutane Cis-C18 Fatty Acid Derivatives Inhibit Mycobacterium Avium Subsp. Paratuberculosis Growth, Denise K. Zinniel, Wantanee Sittiwong, Darrell D. Marshall, Govardhan Rathnaiah, Isin Sakallioglu, Robert Powers, Patrick H. Dussault, Raul G. Barletta

Papers in Veterinary and Biomedical Science

Mycobacterium avium subspecies paratuberculosis (Map) is the etiologic agent of Johne’s disease in ruminants and has been associated with Crohn’s disease in humans. An ective control of Map by either vaccines or chemoprophylaxis is a paramount need for veterinary and possibly human medicine. Given the importance of fatty acids in the biosynthesis of mycolic acids and the mycobacterial cell wall, we tested novel amphiphilic C10 and C18 cyclobutene and cyclobutane fatty acid derivatives for Map inhibition. Microdilution minimal inhibitory concentrations (MIC) with 5 or 7 week endpoints were measured in Middlebrook 7H9 base broth media. We compared the ...

Background: Evaluating clinical outcome prior to concurrent chemoradiotherapy remains challenging for oesophageal squamous cell carcinoma (OSCC) as traditional prognostic markers are assessed at the completion of treatment. Herein, we investigated the potential of using sub-region radiomics as a novel tumour biomarker in predicting overall survival of OSCC patients treated by concurrent chemoradiotherapy. Methods: Independent patient cohorts from two hospitals were included for training (n = 87) and validation (n = 46). Radiomics features were extracted from sub-regions clustered from patients' tumour regions using K-means method. The LASSO regression for ‘Cox’ method was used for feature selection. The survival prediction model was constructed ...

BACKGROUND: Accelerated knee osteoarthritis (AKOA) is characterized by more pain, impaired physical function, and greater likelihood to receive a joint replacement compared to individuals who develop the typical gradual onset of disease. Prognostic tools are needed to determine which structural pathologies precede the development of AKOA compared to individuals without AKOA. Therefore, the purpose of this manuscript was to determine which pre-radiographic structural features precede the development of AKOA.

METHODS: The sample comprised participants in the Osteoarthritis Initiative (OAI) who had at least one radiographically normal knee at baseline (Kellgren-Lawrence [KL] grade < 1). Participants were classified into 2 groups based on radiographic progression from baseline to 48 months: AKOA (KL grade change from < 1 to > 3) and No AKOA. The index visit was ...

Dysfunction In Serotonergic And Noradrenergic Systems And Somatic Symptoms In Psychiatric Disorders, Yi Liu, Jingping Zhao, Xiaoduo Fan, Wenbin Guo

Open Access Articles

Somatic symptoms include a range of physical experiences, such as pain, muscle tension, body shaking, difficulty in breathing, heart palpitation, blushing, fatigue, and sweating. Somatic symptoms are common in major depressive disorder (MDD), anxiety disorders, and some other psychiatric disorders. However, the etiology of somatic symptoms remains unclear. Somatic symptoms could be a response to emotional distress in patients with those psychiatric conditions. Increasing evidence supports the role of aberrant serotoninergic and noradrenergic neurotransmission in somatic symptoms. The physiological alterations underlying diminished serotonin (5-HT) and norepinephrine (NE) signaling may contribute to impaired signal transduction, reduced 5-HT, or NE release from ...

Assessment Of Motor Function, Motor Learning, & Olivary Climbing Fiber Distribution Within Developmental Hyperserotonemia Rat Model For Autism Spectrum Disorder, Elizabeth Diane Holland 2019 Missouri State University

Assessment Of Motor Function, Motor Learning, & Olivary Climbing Fiber Distribution Within Developmental Hyperserotonemia Rat Model For Autism Spectrum Disorder, Elizabeth Diane Holland

MSU Graduate Theses

While Autism Spectrum Disorder (ASD) is defined by deficits in social communication, compromised motor function and motor learning have been increasingly reported. Motor deficits could compound social impairment through delayed language acquisition, reduced opportunity for social interaction, and affected nonverbal communication. One area of interest in the investigation of motor dysfunction is the cerebellum, where altered cerebellar structure and connectivity have been reported in those diagnosed with ASD. Morphological and functional changes in cerebellar circuitry could disrupt motor skill development and may be associated with developmental alterations of the serotonergic system. Elevated blood serotonin in perinatal development, developmental hyperserotonemia (DHS ...

Decomposition Of Pig Carcasses At Varying Room Temperature, Jacqueline Abad Santos 2019 San Jose State University

Decomposition Of Pig Carcasses At Varying Room Temperature, Jacqueline Abad Santos

Themis: Research Journal of Justice Studies and Forensic Science

The goal of this study is to assess the qualitative scoring of decomposition scales with statistical analysis while also determining which indoor environment will decompose the fastest. When comparing the three indoor environments, water decomposition appears to be the fastest, but the method of analysis for this study determines that using decomposition scales to analyze such environments may produce statistically insignificant results. For this study, piglets were put in a dry steel tub, a water filled steel tub, and a suitcase. These were recorded using photographs for 25 days and then scored using decomposition scales. The total score was divided ...
