It's A Hard Nacht Life: Understanding How Nlrp12 Ticks, Abbigale Julia Brown

MSU Graduate Theses

The protein NOD- like receptor pyrin domain containing 12 (NLRP12) comes from a family of protein receptors with a wide range of functions including fertility as well as anti-inflammatory properties. The biological role of NLRP12 is poorly understood: research on the mechanisms behind its function and/or activation remains contradictory between different cell models. Current research suggests its involvement in a multi-protein complex named the inflammasome. The alternative hypothesis that has also been proposed is that NLRP12 is not a part of the inflammasome, rather it negatively regulates a transcription factor known as NF-��B down stream of Toll-like receptors. NLRP12 is …

Individual Free Fatty Acids Have Unique Associations With Inflammatory Biomarkers, Insulin Resistance And Insulin Secretion In Healthy And Gestational Diabetic Pregnant Women., Xinhua Chen, T Peter Stein, Robert A Steer, Theresa O Scholl

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

Objective: We investigated the relationships of maternal circulating individual free fatty acids (FFA) with insulin resistance, insulin secretion and inflammatory biomarkers during mid-pregnancy.

Research design and methods: The data were drawn from a prospective cohort of generally healthy pregnant women (n=1368, African-American 36%, Hispanic 48%, Caucasian 16%) in Camden, NJ. We quantitatively determined 11 FFAs, seven cytokine/adipokine, homeostatic model assessment of insulin resistance (HOMA-IR) and C-peptide levels from the fasting blood samples that were collected at 16 weeks of gestation. Multivariate analyses were performed along with separate analyses for each individual FFA.

Results: High HOMA-IR (p

Conclusion: Our results suggest …

Does Acute Preprandial Exercise Modify Postprandial Inflammation After A High Fat Meal In Young And Older Adults?, William Wisseman

Masters Theses, 2010-2019

A single high-fat meal (HFM) can increase systemic inflammation (postprandial inflammation; PPI) and may be attenuated by recent exercise. However, the effect of preprandial exercise on PPI in older adults (OA) is not clear. Purpose: To determine if preprandial exercise attenuates PPI in YA and OA. Methods: 12 YA (23.3±3.9 years n= 5 M/7 F) and 12 OA (67.7±6 years, n= 8 M/4 F) completed two HFM challenges in a randomized order. During HFM alone, participants abstained from exercise 48 hours prior to the HFM session (except for the exercise session) and adhered to a 12 hour overnight …

Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin

Electronic Theses and Dissertations

Background. Ethanol (EtOH) consumption is known to affect multiple organs; this is unsurprising, as the concentration of EtOH in the blood at relevant doses reaches the millimolar range. The overarching goal of this dissertation was to elucidate mechanisms of alcohol-induced organ injury, specifically the effects of alcohol on the hepatic extracellular matrix (ECM) proteome, the alcoholic hepatitis (AH) plasma peptidome, and the effects of alcohol on the renal cortex proteome and transcriptome. Methods. Mice were pair-fed ethanol-containing liquid diet chronically, and then some mice were administered lipopolysaccharide (LPS). Liver sections from these mice were processed in a series of increasingly …

Direct Lung Sampling Indicates That Established Pathogens Dominate Early Infections In Children With Cystic Fibrosis., Peter Jorth, Zarmina Ehsan Md, Amir Rezayat, Ellen Caldwell, Christopher Pope, John J. Brewington, Christopher H. Goss, Dan Benscoter, John P. Clancy, Pradeep K. Singh

Manuscripts, Articles, Book Chapters and Other Papers

Culture and sequencing have produced divergent hypotheses about cystic fibrosis (CF) lung infections. Culturing suggests that CF lungs are uninfected before colonization by a limited group of CF pathogens. Sequencing suggests diverse communities of mostly oral bacteria inhabit lungs early on and diversity decreases as disease progresses. We studied the lung microbiota of CF children using bronchoscopy and sequencing, with measures to reduce contamination. We found no evidence for oral bacterial communities in lung lavages that lacked CF pathogens. Lavage microbial diversity varied widely, but decreases in diversity appeared to be driven by increased CF pathogen abundance, which reduced the …

Lipids, Reactive Oxygen Species, And Health, Heather Bowen

DNP Research Projects

Cardiovascular disease (CVD) is the leading cause of death in the United States. Coronary artery disease (CAD), where plaque builds up to create atherosclerosis, puts patients at risk for heart attack or stroke. Mitochondrial Reactive Oxygen Species (ROS) have been implicated as a source of oxidative stress that can lead to the development of CAD, and diets high in fat potentiate this occurrence. As certain fats are heated and experience chemical and physical degradation, they cause an increased risk of obesity, diabetes, various forms of cancer, and CVD. This research study, based on CREATION Health ideals, aimed to evaluate the …

Critical Physicochemical Properties For Nanoparticle Toxicity: Impact Of Surface Coating And Size On Particle-Induced Cell Transformation And Inflammatory Response, Tiffany Kornberg

Graduate Theses, Dissertations, and Problem Reports

Nanoparticles, which measure 100 nm in at least one dimension, have surged in development, production, and use for a wide range of applications. However, the rapid pace of development for these emerging materials with unclear/unknown toxicity profiles makes it difficult to adequately assess health risk associated with exposure. One critical obstacle which limits scientific research to fill these critical knowledge gaps is the lack of accurate and predictive models for nanotoxicology studies, particularly those which involve occupationally relevant exposure scenarios (pulmonary exposure to low dose of particles in the circulating air). Typically, animal models are used to assess potential systemic …

Are Chronic Inflammatory Diseases Associated With Trauma Exposure And Gender? An Empirical Analysis Of Self-Reported Trauma And Health Histories Of Men And Women, Meghan Lacienski

Electronic Theses and Dissertations

A growing body of research indicates an association between trauma, inflammation, and chronic inflammatory disease; however, the mechanisms of this relationship are not fully understood, and the salience of potential risk factors, such as cumulative effects of trauma, trauma type, and gender, remain unclear. Trauma is associated with poor mental and physical health, such as PTSD, depression, and chronic inflammatory conditions, and this association may be stronger when certain risk factors are considered (Brody, Pratt, & Hughes, 2018; Groer, Kane, Williams, & Duffy, 2014; Husky, Mazure, & Kovess-Masfety, 2018; Kilpatrick et al., 2013). For example, sexual trauma and multiple traumatic …

Effect Of Propionic Acid-Derivative Ibuprofen On Neural Stem Call Differentiation; A Potential Link To Autism Spectrum Disorder, Aseelia Samsam

Honors Undergraduate Theses

Propionic acid (PPA) is a short chain fatty acid that is produced by the human gut microbiome. Propionate, butyrate and acetates are the end products of the fermentation of the complex carbohydrates by human gut friendly microbiome and are being used as sources of energy in our body. PPA is used as a food preservative against molds in various daily products and has been implicated in the pathogenesis of autism. In a recent study we showed that PPA in human neuronal stem cell (NSC) culture increases the astrocyte population and decreases the neuronal number and increases the inflammatory cytokines. In …
