Proteoglycans In Mechanobiology Of Tissues And Organs: Normal Functions And Mechanopathology, Mary C Farach-Carson, Danielle Wu, Cristiane Miranda França Jan 2024

Proteoglycans In Mechanobiology Of Tissues And Organs: Normal Functions And Mechanopathology, Mary C Farach-Carson, Danielle Wu, Cristiane Miranda França

Faculty, Staff and Student Publications

Proteoglycans (PGs) are a diverse class of glycoconjugates that serve critical functions in normal mechanobiology and mechanopathology. Both the protein cores and attached glycosaminoglycan (GAG) chains function in mechanically-sensitive processes, and loss of either can contribute to development of pathological conditions. PGs function as key components of the extracellular matrix (ECM) where they can serve as mechanosensors in mechanosensitive tissues including bone, cartilage, tendon, blood vessels and soft organs. The mechanical properties of these tissues depend on the presence and function of PGs, which play important roles in tissue elasticity, osmolarity and pressure sensing, and response to physical activity. Tissue …

Is Preexisting Inflamed Jaw Marrow A “Hidden” Co-Morbidity Affecting Outcomes Of Covid-19 Infections? – Clinical Comparative Study, Johann Lechner, Robert E Mcmahon, Jerry E Bouquot, Florian Notter, Fabian Schick

Faculty, Staff and Student Publications

Introduction: Exceedingly high levels of the chemokine CCL5/RANTES have been found in fatty degenerated osteonecrotic alveolar bone cavities (FDOJ) and aseptic ischemic osteolysis of the jaw (AIOJ) from toothless regions. Because CCL5/RANTES seems to have a prominent role in creating the COVID-19 “cytokine storm”, some researchers have used the monoclonal antibody Leronlimab to block the CCR5 on inflammatory cells.

Objective: Is preexisting FDOJ/AIOJ jaw marrow pathology a “hidden” co-morbidity affecting some COVID-19 infections? To what extent does the chronic CCL5/RANTES expression from preexisting FDOJ/AIOJ areas contribute to the progression of the acute cytokine storm in COVID-19 patients?

Methods: Authors report …

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: It is critical for dentists to identify and differentiate primary and permanent teeth, fillings, dental restorations and areas with pathological findings when reviewing dental radiographs to ensure that an accurate diagnosis is made and the optimal treatment can be planned. Unfortunately, dental radiographs are sometimes read incorrectly due to human error or low-quality images. While secondary or group review can help catch errors, many dentists work in practice alone and/or do not have time to review all of their patients' radiographs with another dentist. Artificial intelligence may facilitate the accurate interpretation of radiographs. To help support the review of …

Bayesian Rare Variant Analysis Identifies Novel Schizophrenia Putative Risk Genes, Shengtong Han Jan 2024

Bayesian Rare Variant Analysis Identifies Novel Schizophrenia Putative Risk Genes, Shengtong Han

School of Dentistry Faculty Research and Publications

The genetics of schizophrenia is so complex that it involves both common variants and rare variants. Rare variant association studies of schizophrenia are challenging because statistical methods for rare variant analysis are under-powered due to the rarity of rare variants. The recent Schizophrenia Exome meta-analysis (SCHEMA) consortium, the largest consortium in this field to date, has successfully identified 10 schizophrenia risk genes from ultra-rare variants by burden test, while more risk genes remain to be discovered by more powerful rare variant association test methods. In this study, we use a recently developed Bayesian rare variant association method that is powerful …

Influence Of Scaling And Root Planing With Minocycline Microspheres On Clinical Outcomes Of Patients With Periodontitis, Nupoor Sandeep Kulkarni Jan 2024

Influence Of Scaling And Root Planing With Minocycline Microspheres On Clinical Outcomes Of Patients With Periodontitis, Nupoor Sandeep Kulkarni

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background: Scaling and root planning (SRP) has been established as a “gold-standard” non-surgical initial treatment for periodontitis. Along with SRP, some systemic adjuncts like systemic antibiotics were used in the past to gain maximum benefits of SRP by reducing the need for further periodontal surgeries. Due to some drawbacks of systemic antibiotic use, like “transient antibiotic resistance”, “non-adherence” and “insufficient concentrations in the periodontal pockets to be clinically effective”, there was a shift towards the use of local antibiotic adjuncts to SRP like minocycline, tetracycline, chlorhexidine etc. Minocycline is a semi-synthetic tetracycline derivative which is available in a powder form, …
