The Development Of A Temporomandibular Force Simulator To Study Craniofacial Strain In-Vitro, Kenneth KC Ip 2018 The University of Western Ontario

The Development Of A Temporomandibular Force Simulator To Study Craniofacial Strain In-Vitro, Kenneth Kc Ip

Electronic Thesis and Dissertation Repository

An in-vitro musculoskeletal loading simulator was developed to replicate the internal forces of mastication, and then employed in a comparison of clinically relevant facial fracture repairs. Muscle forces are simulated by pneumatic pistons via 3D printed mounts that are reverse-engineered from CT scan to match muscle attachment sites, which are adhered to bone in order to simulate native stress distributions. Bite force and bone strain pattern of the craniofacial structure under load were measured using a force sensor and strain gauges respectively. In a series of five fresh-frozen cadaveric heads, it was found that strain patterns of the craniofacial structure ...

Identification Of Epigenetic Regulators Of Dux4-Fl For Targeted Therapy Of Facioscapulohumeral Muscular Dystrophy, Charis L. Himeda, Takako I. Jones, Ching-Man A. Virbasius, Lihua Julie Zhu, Michael R. Green, Peter L. Jones 2018 University of Massachusetts Medical School

Identification Of Epigenetic Regulators Of Dux4-Fl For Targeted Therapy Of Facioscapulohumeral Muscular Dystrophy, Charis L. Himeda, Takako I. Jones, Ching-Man A. Virbasius, Lihua Julie Zhu, Michael R. Green, Peter L. Jones

Open Access Articles

Facioscapulohumeral muscular dystrophy (FSHD) is caused by epigenetic de-repression of the disease locus, leading to pathogenic misexpression of the DUX4 gene in skeletal muscle. While the factors and pathways involved in normal repression of the FSHD locus in healthy cells have been well characterized, very little is known about those responsible for the aberrant activation of DUX4-fl in FSHD myocytes. Reasoning that DUX4-fl activators might represent useful targets for small molecule inhibition, we performed a highly targeted, candidate-based screen of epigenetic regulators in primary FSHD myocytes. We confirmed several of the strongest and most specific candidates (ASH1L, BRD2, KDM4C, and ...

Towards An Arthritis Flare-Responsive Drug Delivery System, Nitin Joshi, Ellen M. Gravallese, Joerg Ermann, Jeffrey M. Karp

Open Access Articles

Local delivery of therapeutics for the treatment of inflammatory arthritis (IA) is limited by short intra-articular half-lives. Since IA severity often fluctuates over time, a local drug delivery method that titrates drug release to arthritis activity would represent an attractive paradigm in IA therapy. Here we report the development of a hydrogel platform that exhibits disassembly and drug release controlled by the concentration of enzymes expressed during arthritis flares. In vitro, hydrogel loaded with triamcinolone acetonide (TA) releases drug on-demand upon exposure to enzymes or synovial fluid from patients with rheumatoid arthritis. In arthritic mice, hydrogel loaded with a fluorescent ...

Urinary Tract Infection In Children With Spina Bifida And Spinal Cord Injury., Obumneke Amadi, Harolyn Belcher

GW Research Days 2016 - Present

Introduction: Urinary tract infections (UTI) are one of the most common bacterial infections (Schappert & Rechtsteiner, 2008; Litwin et al., 2005). Data from the National Ambulatory Medical Care Survey estimated that UTI caused 8.1 million physicians visits (Schappert & Rechtsteiner, 2008). Children with spina bifida (SB) and spinal cord injury (SCI) are at high risk for UTI (Ouyang et al., 2010; Nair et al., 2005). The purpose of this study was to examine the organisms associated with UTI in the population of children with SB and SCI who were treated in out-patient and in-patient settings at the Kennedy Krieger Institute (KKI).

Objective: To examine the organisms and antibiotic resistance patterns that cause UTI in SB and SCI in the population of children who are treated ...

Analysis Of Subchondral Bone And Microvessels Using A Novel Vascular Perfusion Contrast Agent And Optimized Dual-Energy Computed Tomography, Justin J. Tse

Electronic Thesis and Dissertation Repository

Osteoarthritis (OA), is a chronic debilitating disease that affects millions of individuals and is characterized by the degeneration of joint subchondral bone and cartilage. These tissue degenerations manifest as joint pain, limited range of joint motion, and overall diminished quality of life. Currently, the exact mechanism(s) and cause(s) by which OA initiates and progresses remain unknown. The multi-factorial complex nature of OA (i.e. age, diabetes, obesity, and prior injuries have all been shown to play a role in OA) contributes to the current lack of a cure or effective long-term treatment for OA.

One re-emerging and interesting ...

Open Access Articles

Background: Tumor necrosis factor alpha (TNFalpha) is a key cytokine in both the pathogenesis of inflammatory bowel disease (IBD) and rheumatoid arthritis (RA) and the host defense against tuberculosis (TB). Consequently, anti-TNFalpha medications result in an increased risk of latent TB infection (LTBI) reactivation. Here, we sought to evaluate the factors affecting the results of QuantiFERON-TB Gold In-Tube (QFT-GIT) assay as a screening tool for LTBI.

Methods: We conducted an observational, retrospective study in patients with IBD and RA who underwent LTBI screening using QFT-GIT at UMass Memorial Medical Center between 2008 and 2016 prior to initiation of anti-TNF medications ...

A Cre-Inducible Dux4 Transgenic Mouse Model For Investigating Facioscapulohumeral Muscular Dystrophy, Takako I. Jones, Peter L. Jones

Open Access Articles

The Double homeobox 4 (DUX4) gene is an important regulator of early human development and its aberrant expression is causal for facioscapulohumeral muscular dystrophy (FSHD). The DUX4-full length (DUX4-fl) mRNA splice isoform encodes a transcriptional activator; however, DUX4 and its unique DNA binding preferences are specific to old-world primates. Regardless, the somatic cytotoxicity caused by DUX4 expression is conserved when expressed in cells and animals ranging from fly to mouse. Thus, viable animal models based on DUX4-fl expression have been difficult to generate due in large part to overt developmental toxicity of low DUX4-fl expression from leaky transgenes. We have ...

BACKGROUND: Registry studies provide a valuable source of comparative safety data for tumor necrosis factor inhibitors (TNFi) used in rheumatoid arthritis (RA), but they are subject to channeling bias. Comparing safety outcomes without accounting for channeling bias can lead to inaccurate comparisons between TNFi prescribed at different stages of the disease. In the present study, we examined the incidence of serious infection and other adverse events during certolizumab pegol (CZP) use vs other TNFi in a U.S. RA cohort before and after using a methodological approach to minimize channeling bias.

METHODS: Patients with RA enrolled in the Corrona registry ...
