Characterization Of Adiposity And Inflammation Genetic Pleiotropy Underlying Cardiovascular Risk Factors In Hispanics., Mohammad Yaser (Anwar)
Characterization Of Adiposity And Inflammation Genetic Pleiotropy Underlying Cardiovascular Risk Factors In Hispanics., Mohammad Yaser (Anwar)
Electronic Theses and Dissertations
The observed overlap between genetic variants associated with both adiposity and inflammatory markers suggests that changes in both adiposity and inflammation could be partially mediated by common pathways. The pervasive but sparsely characterized “pleiotropic” genetic variants associated with both adiposity and inflammation have been hypothesized to provide insight into the shared biology. This study explored and characterized the genetic pleiotropy underpinning adiposity and inflammation using genetic and phenotypic observations from the Cameron County Hispanic Cohort (CCHC). A total of 3,313 samples and >9 million single nucleotide polymorphisms (SNPs) were examined in this study. Mixed model genome-wide association studies (GWAS) were …
Modulation Of Inflammatory Pathway By Inflammatory Inhibitor Jsh-23 Mitigates Diabetic Retinopathy., Rubens Petit Homme
Modulation Of Inflammatory Pathway By Inflammatory Inhibitor Jsh-23 Mitigates Diabetic Retinopathy., Rubens Petit Homme
Electronic Theses and Dissertations
Diabetic retinopathy (DR) is the most common microvascular complication of diabetes mellitus (DM). Its pathology is consisted of the breakdown of the blood-retinal barrier (BRB), particularly the inner blood-retinal barrier (iBRB). The exact mechanism that leads to the iBRB impairment and the development of DR has not been elucidated yet. However, chronic inflammation that is hallmark of the type I DM has recently become a key focus in DR study. Hyperglycemia causes dysregulation of nuclear factor-kappa B (NF-kB); and its constant activation increases the expression of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and intercellular adhesion molecule-1 (ICAM-1) in the …
Plasmodium Impairs Antibacterial Innate Immunity To Systemic Infections In Part Through Hemozoin-Bound Bioactive Molecules., Christopher Lynn Harding
Plasmodium Impairs Antibacterial Innate Immunity To Systemic Infections In Part Through Hemozoin-Bound Bioactive Molecules., Christopher Lynn Harding
Electronic Theses and Dissertations
Despite efforts to decrease the global health burden of malaria, infections with Plasmodium species continue to cause over 200 million episodes of malaria each year which resulted in 405,000 deaths in 2018 [1]. One complication of malaria is increased susceptibility to invasive bacterial infections. Plasmodium infections impair host immunity to non-Typhoid Salmonella (NTS) through activities of heme oxygenase I (HO-I) )-induced release of immature granulocytes and myeloid cell-derived IL-10. Yet, it is not known if these mechanisms are specific to NTS. We show here, that Plasmodium yoelii 17XNL (Py) infected mice had impaired clearance of systemic Listeria monocytogenes (Lm) during …
The Emerging Oral Pathogen, Filifactor Alocis, Disrupts Neutrophil Functions To Enhance Survival And Dysregulate Inflammation., Irina Miralda Molina
The Emerging Oral Pathogen, Filifactor Alocis, Disrupts Neutrophil Functions To Enhance Survival And Dysregulate Inflammation., Irina Miralda Molina
Electronic Theses and Dissertations
Periodontitis is an irreversible, chronic inflammatory disease where pathogenic microbial communities accumulate in the gingival crevice. Advances in culture-independent techniques have facilitated the identification of new bacterial species in periodontal lesions, such as the Gram-positive anaerobe, Filifactor alocis. Neutrophils are a major component of the innate host response, and the outcome of their interaction with F. alocis may be a determinant of oral health status. While neutrophil functions typically protect the host against periodontal disease, oral pathogens have adapted to evade or disarm neutrophil microbicidal functions while promoting mechanisms that drive inflammation, which also provides a source of nutrients …
Volatile Organic Compound Exposure And Cardiometabolic Syndrome Risk In A Nationally Representative Cohort., Stacey Lane Konkle
Volatile Organic Compound Exposure And Cardiometabolic Syndrome Risk In A Nationally Representative Cohort., Stacey Lane Konkle
Electronic Theses and Dissertations
BACKGROUND: The relative importance of environmental exposures such as volatile organic compounds (VOCs) is one of the paramount public health priorities of our time, yet is presently unstudied. VOCs are ubiquitous in the environment and have been associated with numerous adverse health effects, including a number of cardiovascular and metabolic effects that are components of Cardiometabolic Syndrome (CMS). OBJECTIVES: To examine the relationship between CMS and individual-level exposures to VOCs, measured as urinary metabolites of VOCs (UM-VOCs), in a nationally representative sample. METHODS: Associations between urinary biomarkers of exposure to 19 parent VOCs and CMS were assessed using the National …
Tobacco-Derived Aldehydes: Platelet Activation, Thrombosis, And The Role Of Trpa1., Andre Dwayne Richardson
Tobacco-Derived Aldehydes: Platelet Activation, Thrombosis, And The Role Of Trpa1., Andre Dwayne Richardson
Electronic Theses and Dissertations
Cigarette smoking is the single largest risk factor for cardiovascular disease (CVD) pathophysiology. Numerous researchers have shown potential associations between aldehydes in tobacco-derived aerosols from mainstream cigarette smoke (MCS) or electronic cigarettes (e-cigs) and their cardiotoxicity by damaging blood vessel endothelium. The severity of exposure to these toxicants can furthermore lead to adverse cardiovascular outcomes such as myocardial infarctions, stroke, coronary and peripheral artery disease, or atherosclerosis due to blood clots, a pro-thrombotic event. However, the mechanisms by which levels of harmful and potentially harmful constituents (HPHCs) such as aldehydes induce thrombosis are not well-known. Of specific interest, evidence has …
Development Of Rationally Designed Live Attenuated Vaccines For Lassa Fever And Venezuelan Equine Encephalitis., Dylan Macgregor Johnson
Development Of Rationally Designed Live Attenuated Vaccines For Lassa Fever And Venezuelan Equine Encephalitis., Dylan Macgregor Johnson
Electronic Theses and Dissertations
Lassa Virus (LASV) and Venezuelan Equine Encephalitis Virus (VEEV) are two single stranded RNA viruses belonging to the Arenavirus and Alphavirus families, respectively. Both are emerging pathogens without approved vaccines or treatments. VEEV is an important biothreat pathogen because it has been weaponized and is extremely infectious as an aerosol. VEEV causes biphasic febrile illness that can progress to a viral encephalitis with low mortality, but high morbidity. LASV causes a viral hemorrhagic fever, Lassa Fever (LF), which is endemic in West Africa, and responsible for between 100-500k annual infections with a 1-2% overall mortality rate. ML29 and VEEV TC-83 …
Tobacco Product-Derived Aldehydes: Effects On Circulating Angiogenic Cells & Implications For Cardiovascular Disease., Jordan B. Lynch
Tobacco Product-Derived Aldehydes: Effects On Circulating Angiogenic Cells & Implications For Cardiovascular Disease., Jordan B. Lynch
Electronic Theses and Dissertations
Cardiovascular disease (CVD) is the leading cause of death worldwide. Tobacco smoke is the most significant modifiable risk factor in CVD development and contains numerous toxic compounds, including aldehydes, which have been linked to CVD. Formaldehyde, acetaldehyde, acrolein, and crotonaldehyde have been identified as significant contributors to cigarette-induced health effects, but the mechanism of these effects is not well understood. These aldehydes are also found in aerosols produced by e-cigarettes (e-cigs). The goal of this dissertation was to explore the systemic, hematological, and endothelium-related effects of exposure to tobacco products and constituent aldehydes and to identify potential mechanisms of injury. …
Dual Role Of Antimicrobial Peptide Cathelicidin In Alcohol-Associated Liver Disease., Fengyuan Li
Dual Role Of Antimicrobial Peptide Cathelicidin In Alcohol-Associated Liver Disease., Fengyuan Li
Electronic Theses and Dissertations
Patients with alcohol-associated liver disease (ALD) have high morbidity and mortality in its severe forms. One of the major features in different forms of ALD is the altered gut microbiota. Antimicrobial peptides (AMPs) play a crucial role in maintaining gut microbiota homeostasis. LL-37 (known as CRAMP in mouse) is the sole member of the human cathelicidin family and has piqued great research interest for its dual role in modulating microbiota and the immune response in metabolic diseases. Inflammasome activation is an important component of the liver pathophysiology in ALD and requires two signals for its full activation to induce the …
