Comorbid Metabolic Syndrome And Prodromal Alzheimer's Disease In A Rat Model, Nadezda Ivanova

Electronic Thesis and Dissertation Repository

Metabolic syndrome (MetS), the development of which is associated with high-caloric Western diet intake, represents a risk factor for mild cognitive impairment (MCI) and Alzheimer’s disease (AD) and appears to contribute to AD progression when MetS and AD are comorbid. The interaction between AD and MetS might be through white matter inflammation, since white matter abnormalities and inflammation are important early events in the etiopathogenesis of both diseases. In these investigations, the effect of a high-caloric diet (HCD), to induce metabolic disturbances, on white matter neuroinflammation and cognitive function was investigated in a transgenic (TG) rat model of prodromal AD …

OBJECTIVES: Vitamin D deficiency/insufficiency is a worldwide public health issue that has been linked to numerous inflammatory disorders, including periodontitis. There is increasing support for a role for adequate vitamin D levels in overall health. Populations with darker skin color have a higher prevalence of vitamin D deficiency/insufficiency and periodontitis. The purpose of this small pilot study was to investigate the influence of 12 weeks of 25(OH)D vitamin D supplementation (VDS) on mediators of systemic inflammation in dark-skinned, periodontitis patients.

MATERIALS AND METHODS: A total of 23 patients with moderate to severe periodontitis were randomly assigned to the vitamin D …

The Effect Of Emdogain Periodontal Regenerative Material On Inflammation In Periodontal Maintenance Patients, Jessica M. Gradoville

Theses & Dissertations

The purpose of this double-blinded, randomized, controlled clinical trial was to determine if local application of enamel matrix protein derivative (Emdogain:EMD), combined with minimally-invasive papilla reflection is effective in reducing inflammation in periodontal pockets in patients on periodontal maintenance therapy (PMT).Fifty patients diagnosed with advanced chronic periodontitis presenting with a 6-9mm interproximal probing depth were included in the trial. Experimental (EMD; n=24) and control (saline, n=26) therapies were randomly allocated. Roots were treated with mini-flaps and root planing assisted with endoscope evaluation before EMD or saline application. Inflammation was assessed by bleeding on probing (BOP) at baseline, 6-, and 12-months …

The release of the prototypic DAMP High Mobility Group Box 1 (HMGB1) into extracellular environment and its binding to the Receptor for Advanced Glycation End Products (RAGE) has been described to trigger sterile inflammation and regulate healing outcome. However, their role on host response to Ti-based biomaterials and in the subsequent osseointegration remains unexplored. In this study, HMGB1 and RAGE inhibition in the Ti-mediated osseointegration were investigated in C57Bl/6 mice. C57Bl/6 mice received a Ti-device implantation (Ti-screw in the edentulous alveolar crest and a Ti-disc in the subcutaneous tissue) and were evaluated by microscopic (microCT [bone] and histology [bone and …

Possible Pathologic Effect Of Hmgb1 On P. Gingivalis Induced Inflammatory Response By Macrophages, Michelle Marie Torres Santos

Student Theses, Dissertations and Capstones

BACKGROUND: Periodontitis is an inflammatory disease caused by poly-microbial infection that leads to destruction of connective tissue and alveolar bone. It is well documented that bacteria-derived virulent factors that can act on Toll-like receptors (TLRs), represented by Lipopolysaccharides (LPS), are engaged in the initiation of inflammatory responses. However, while LPS is also produced by the bacteria colonized in the healthy periodontal tissue, inflammation is not induced by LPS in those periodontal healthy subjects, suggesting the requirement of additional factor to upregulate the LPS-mediated inflammatory response in periodontal tissue. Recent studies revealed that novel class of endogenous proinflammatory mediator, high mobility …

Puberty: Is Your Gingiva Having Mood Swings?, Gabrielle R. Salvatore, Kendall A. Connerley

Dental Hygiene Student Scholarship

Objectives/aim: The purpose of this paper is to explore the effects on the different pathological changes in the oral cavity due to puberty, in both males and females. Hormonal changes caused by menstrual cycles, ovulation, the use contraceptives, and increased testosterone and estrogen levels.

Methods: This topic will be analyzed by thoroughly reviewing research on articles that relate to the oral health of individuals specifically between the ages of 12-18 years old.

Results: Research presents significant evidence that supports changes occurring in the oral cavity during an individual’s stage of puberty. These stages include ovulation, pre-menstruation, menstruation and males transitioning …

Background/aim: Multipotent mesenchymal stem cells (MSCs) have been investigated in autoimmune diseases such as rheumatoid arthritis (RA) due to their immunomodulatory and regenerative properties. In this study, their immunosuppressive effects on peripheral blood mononuclear cells (PBMC) of RA patients were studied.Materials and methods: Dental follicle stem cells (DFSCs) were isolated from follicle tissue in the orofacial region. Characterization and multipotency analyses were performed. Lymphocytes were isolated from peripheral venous blood of RA patients (n = 5) and healthy individuals (n = 5). DFSCs were preincubated with IFN-γ for 48 h. PBMCs of RA patients and healthy individuals were separately cultured …
