The Relationship Between Tree Canopy And Social Capital On Physical Activity In Unlv Students, Melissa Bartshe
The Relationship Between Tree Canopy And Social Capital On Physical Activity In Unlv Students, Melissa Bartshe
UNLV Theses, Dissertations, Professional Papers, and Capstones
Despite the numerous health benefits, rates of physical activity are low, especially among the college student population. Neighborhood tree canopy is one aspect of the built environment that has been shown to positively impact physical activity. Social capital has also been correlated with higher rates of physical activity. The sprawling urban design and arid desert climate of Las Vegas pose unique challenges to both tree canopy and social capital. Additionally, the relationship between tree canopy, social capital, and physical activity is understudied in the college student population. The purpose of this study was to assess the relationship of tree canopy …

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 …
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. …

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 …

Antinéoplasiques En Milieu Hospitalier : Étude Pilote Sur L’Exposition Potentielle Du Personnel D’Hygiène Et De Salubrité, France Labrèche, Capucine Ouellet, Brigitte Roberge, Ahmed Yennek, Nicolas Caron
Rapports de recherche scientifique
Certains antinéoplasiques (ANP), utilisés pour le traitement du cancer, sont eux-mêmes classés cancérogènes et peuvent avoir d’autres effets toxiques chez des travailleurs qui les manipulent. L’incidence du cancer et le nombre de personnes vivant avec le cancer ne cessent d’augmenter, ce qui permet d’envisager une augmentation des quantités d’ANP utilisées et du nombre de travailleurs potentiellement exposés. Une étude menée par l’Unité de recherche en pratique pharmaceutique du Centre hospitalier universitaire Ste-Justine a montré que plusieurs prélèvements effectués sur des surfaces touchées par le personnel infirmier et par celui de la pharmacie montraient des résidus d’ANP. Il n’y a cependant …
Antidepressants Versus Music Therapy: Which Treatment Is Better For Treating Depression In Parkinson's Disease?, Emaan Dawood
Antidepressants Versus Music Therapy: Which Treatment Is Better For Treating Depression In Parkinson's Disease?, Emaan Dawood
Virginias Collegiate Honors Council Conference
Music and medicine are merging to treat depression in Parkinson’s disease (PD). Antidepressants, the current standard, demonstrate mixed effects in clinical trials, warranting other treatment options. Here, I compare music therapy to antidepressants in the treatment of depression in PD via literature review. Studies of depressed PD patients undergoing music therapy and/or antidepressants were reviewed with attention to variables including depression (on a patient-reported outcome) that were measured pre- and post- therapy. In the music studies, improvements were seen in depression. Methodological inconsistencies across these studies, a paucity of studies, and small sample sizes, however, necessitate more research to reach …

The Reliability Of Histamine Pharmacodynamic Response Phenotype Classification In Children With Allergic Disease., Shaun S Kumar, Xiaoxi Liu, Catherine M Sherwin, Bridgette Jones
Manuscripts, Articles, Book Chapters and Other Papers
We have identified distinct histamine pharmacodynamic response phenotypes in children with allergic disease utilizing histamine iontophoresis with laser Doppler (HILD). These response phenotypes may be relevant in guiding therapeutic decision making for agents targeting the allergic response pathways. However, the reliability of these response phenotypes has not been assessed. Therefore, we performed HILD in children with allergic rhinitis and/or asthma on two to three separate occasions. HILD response-time data were analyzed in NONMEM using a linked effect PKPD model. Examination of observed vs. classified response phenotypes predicted response plots and the sum of residuals. The intraclass correlation coefficient (ICC) was …

Activation Of The Sonic Hedgehog Effector Smoothened Counteracts L-Dopa Induced Dyskinesia By Restoring Cholinergic Interneuron Function, Lauren Malave
Dissertations, Theses, and Capstone Projects
Many types of neurons act as multimodal signaling centers. Yet, we have only limited insight into the regulation and functional consequences of neuronal co-transmission. For example, dopamine (DA) neurons, whose degeneration causes motor deficits characteristic of Parkinson’s Diseases (PD), communicate with all their targets by DA but only a selective subset of their targets using GABA, Glutamate, and the secreted cell signaling protein Sonic Hedgehog (Shh). It is unknown whether Levo-dopamine (L-Dopa) induced dyskinesia (LIDs), a severely debilitating side effect of DA supplementation in PD, might appear because DA neuron targets are exposed to high DA- but low Shh- signaling …

Parp1-Targeted Radiotherapies, Stephen Jannetti
Dissertations, Theses, and Capstone Projects
Poly-ADP-ribosylation reactions were first reported by Chambon in 1963 as enzymatic activity that increases incorporation of ATP in the presence of nicotinamide mononucleotide. In the decades since that publication, Poly(ADP-ribose)polymerase 1 (PARP1) and the PARP family enzymes have been widely studied. PARP enzymes are currently known to play various roles in mammals, including anti-aging processes, interactions with Breast Cancer Suppressor Protein-1 (BRCA1), and DNA damage repair. A significant focus of PARP1 research has been elucidating its role in DNA damage repair. PARP1 is recruited to repair single strand DNA (ssDNA) breaks, which can become double stranded DNA (dsDNA) breaks if …
Functional Significance Of Endothelial Sigma-1 Receptors In Vascular Reactivity And Barrier Function, Zeinab Y. Motawe
Functional Significance Of Endothelial Sigma-1 Receptors In Vascular Reactivity And Barrier Function, Zeinab Y. Motawe
USF Tampa Graduate Theses and Dissertations
The sigma-1 receptor (σ1) is a single 25 kD polypeptide that acts as a chaperone protein residing primarily in the endoplasmic reticulum Its interaction with mitochondria at the mitochondria-associated ER membrane domain is well-documented. Following activation, σ1 binds to the inositol trisphosphate receptor (Hayashi & Su), and modulates intracellular calcium homeostasis. Also, the activated σ1 modulates plasma membrane receptors and ion channel functions, and may regulate cellular excitability. Further, σ1 affects trafficking of lipids and proteins essential for neurotransmission, cell growth and motility. Activation of σ1 provides neuroprotection and cardio-protection in various models. Examples of neuroprotection include but not limited …

Department of Biological & Biomedical Sciences
Background: Multiple-drug-resistant Gram-negative bacteria (MDR-GNB)-associated neonatal ventriculitis is a life-threatening complication that needs timely diagnosis and effective treatment with broad-spectrum antimicrobials in critical-care settings. Inadequate penetration of antibiotics through the blood-brain barrier also demands an intraventricular (IVT) route of administration. This study reports mortality and neurodevelopmental sequelae of neonates till 18 months of age, who received IVT-colistin for treating MDR-GNB associated ventriculitis.
Methods: In a case series of seven neonates with ventriculitis due to MDR-GNB at NICU of Aga Khan University Hospital, Pakistan, between June 2015 and 2018, we reviewed IVT-colistin therapy in critically ill neonates. Treatment outcomes were assessed …
Mechanisms Of Dopamine-Induced Methamphetamine Neurotoxicity, Melinda L. Asbury
Mechanisms Of Dopamine-Induced Methamphetamine Neurotoxicity, Melinda L. Asbury
Theses, Dissertations and Capstones
Methamphetamine (MA) neurotoxicity is particularly evident in the striatum where it causes extensive dopamine (DA) release and results in neurodegeneration. To identify specific signaling pathways and macromolecules involved in postsynaptic DA-induced striatal toxicity we used a SK-N-MC cell model that mimics postsynaptic D1 receptor-expressing striatal neurons. The cells were treated for 6-24 h with 0-50 µM DA. The concentration was chosen to impart physiological relevance to the study as it mirrors [DA] found within the striatum following MA exposure. We show that 25-50 µM DA resulted in protein changes consistent with nitro(oxidative) stress as well as enhanced cleavage of caspase …
