Perivascular Waste Metabolites Clearance In Central Nervous System (Cns), Yiming Cheng
Perivascular Waste Metabolites Clearance In Central Nervous System (Cns), Yiming Cheng
Dissertations
Efficient clearance of interstitial waste metabolites is essential for normal brain homeostasis. Such effective clearance is hampered by the lack of a lymphatic system in the brain, and the cerebrospinal fluid (CSF) is unable to clear large size waste metabolites in the brain. Here, a novel idea that brain arterial endothelium and smooth muscle cells reactivity regulates the clearance of these water-insoluble large size waste metabolites through the perivascular dynamic exchange, and that low dose ethanol promotes this perivascular clearance is proposed.
In Aim 1, the biodistribution of a large size waste metabolite (Amyloid-β protein mimic) in rat perivascular space …

Preoperative Smoking Cessation Education Plan For Patients And Health Care Professionals, Amy Anderson
Preoperative Smoking Cessation Education Plan For Patients And Health Care Professionals, Amy Anderson
Nursing Capstones
Surgical site infections are an undesired consequence of surgery. Smoking has been identified as a risk factor for developing a postoperative infection (Anderson, 2019). Patients undergoing elective colorectal surgery should be required to be tobacco-free for at least four weeks before surgery. Health care organizations can implement a preoperative smoking cessation program within their facility to assist patients in achieving this requirement. To do so, an education plan is needed to effectively disseminate the main components of the program to both patients and health care professionals. The efficacy of the education plan can be exponentially increased by selecting learning strategies …

Precarity Beyond Food: How The Closure Of An Independent Grocery Store Shed Light On The Limitations Of Food Access Efforts In Syracuse, New York, Katherine Louisa Ravene Mott
Precarity Beyond Food: How The Closure Of An Independent Grocery Store Shed Light On The Limitations Of Food Access Efforts In Syracuse, New York, Katherine Louisa Ravene Mott
Theses - ALL
On September 11, 2017, the owner of an independent grocery store in Syracuse, New York’s Near Westside neighborhood announced that the store would close within the month. The Near Westside is often characterized by its high levels of concentrated poverty for African American and Hispanic neighborhood residents. Nojaim Brothers Supermarket opened in 1919 and persisted for 97 years amidst an unfavorable political and economic landscape marked by the creation of both chain grocery stores and supermarkets as well as the effects of urban renewal and disinvestment. I argue that Nojaim’s endurance can be attributed to the embeddedness of the grocery …
Charge-Based Optimization Of Neurotensin For Neurotensin-Receptor-1 Targeting Utilizing A One-Bead One-Compound Peptide Library Approach, Trey Neeley
Theses & Dissertations
Neurotensin-receptor-1 (NTSR1) is regularly overexpressed in various cancers and contributes to the proliferation, survival, migration, invasion, and angiogenesis of tumors. NTSR1-targeting vectors have demonstrated promise in both diagnostic and therapeutic aspects. Unfortunately, the relatively poor in vivo metabolic stability and high renal uptake and retention of NTSR1-targeted compounds have hampered the translation to the clinic. In this research, we utilized a one-bead one-compound (OBOC) peptide library approach to make targeted modifications at the naturally charged residues of an NTS (4-13) sequence to discover an NTS derivative with comparable affinity to NTSR1, acceptable in vivo stability, and tolerable renal retention. Subsequent …

Computational Studies And Design Of Pparγ And Glut1 Inhibitors, Suliman Almahmoud
Theses & Dissertations
The peroxisome proliferator-activated receptor gamma (PPARγ) is a ligand-dependent transcription factor of the nuclear receptor superfamily that controls the expression of a variety of genes involved in fatty acid metabolism, adipogenesis, and insulin sensitivity. PPARγ is a target for insulin-sensitizing drugs, and it plays a significant function in prostate cancer. PPARγ antagonists have anti-proliferative effects in a broad range of hematopoietic and epithelial cell lines. The ligand binding domain (LBD) of PPARγ is large and has orthosteric and allosteric binding sites. Several PPARγ-ligand co-crystal structures show two bound molecules, one to the orthosteric pocket and a second to the allosteric …
Hiv-1 Elimination In Humanized Mice, Hang Su
Hiv-1 Elimination In Humanized Mice, Hang Su
Theses & Dissertations
Human immunodeficiency virus type one (HIV-1) exclusively infects humans and chimpanzees. Therefore, animal models are required for all investigations of viral pathogenesis, therapy and cure. Immunodeficient mice transplanted with human hematopoietic stem cells, termed humanized mice, support the development of multiple human cell lineages throughout the cell’s life span. To this end, we used humanized mice to evaluate the dynamic changes of host immunologic and viral profiles during both acute and chronic HIV-1 infection. We identified the temporal and spatial distribution of HIV-1 cell and tissue compartment infections and outlined correlations made between viral progression and host immunity by comparing …

Characterizing The Combination Of Rpa Inhibitors With Parp Inhibitors In High-Grade Serous Ovarian Cancer, Yat Tang
Theses & Dissertations
High-grade serous ovarian cancer (HGSC) is the most common and deadly gynecologic malignancy. HGSC patients with BRCA1/2 mutations have homologous recombination deficiency (HRD), requiring parallel pathways to maintain genome integrity (e.g., PARP1, PARP2). Approximately 50% of ovarian carcinomas are estimated to exhibit HRD. For the remaining 50% and the large percentage of HRD patients with acquired or innate resistance to single-agent PARP inhibitors, there is a need to develop alternative therapeutic strategies.
Replication Protein A (RPA) is a heterotrimeric protein crucial for genome maintenance. Phosphorylation of RPA in DNA damage response (DDR) is a negative regulator of DNA end resection. …
Identification Of More Potent And Efficacious Analogs Of The Novel Host-Derived Immunostimulant Ep67, Abdul Alshammari
Identification Of More Potent And Efficacious Analogs Of The Novel Host-Derived Immunostimulant Ep67, Abdul Alshammari
Theses & Dissertations
EP67 is a human C5a-derived decapeptide agonist of C5a Receptor 1 (C5aR1/CD88) that selectively activates mononuclear phagocytes over neutrophils to stimulate protective innate and adaptive immune responses while potentially minimizing neutrophil-mediated toxicity. Two N-alkyl amino acids Pro7 and N-methyl-Leu8 (nme-Leu8) within EP67 induce structural changes that increase potency and selective activation of mononuclear phagocytes over neutrophils. Cis/trans isomerization at these positions, however, likely limits the activity of EP67 and low coupling efficiency between Pro7 and nme-Leu8 increases scale-up costs for clinical use. Thus, the goals of this study were to …
Defining The Role Of Tyrosine Phosphorylation In The Regulation Of Connexin43 In Cardiac Diseases, Li Zheng
Defining The Role Of Tyrosine Phosphorylation In The Regulation Of Connexin43 In Cardiac Diseases, Li Zheng
Theses & Dissertations
Connexins are integral membrane proteins that oligomerize to form gap junction channels. Ions and small molecules diffuse intercellularly through these channels, allowing individual cellular events to synchronize into the functional response of an entire organ. Gap junction channels composed of Connexin43 (Cx43) mediate electrical coupling and impulse propagation in the normal working myocardium. In the failing heart, Cx43 remodeling (decreased expression, altered phosphorylation state, loss at intercalated discs, and increased presence at lateral membranes) contributes to rhythm disturbances and contractile dysfunction. While there is considerable information regarding key interactions of Cx43 in the regulation of gap junction channels, unfortunately, the …
Enhancing The Identification Of Rheumatoid Arthritis-Associated Lung Disease, Bryant England
Enhancing The Identification Of Rheumatoid Arthritis-Associated Lung Disease, Bryant England
Theses & Dissertations
Rheumatoid arthritis (RA) is a systemic autoimmune disease that predisposes afflicted individuals to reduced quality of life, physical disability, and premature mortality. While joint involvement is the primary manifestation of RA, extra-articular features including lung disease are responsible for a significant portion of the excess mortality. In this dissertation I demonstrate the contribution of chronic lung diseases to premature mortality in RA, contrasting with the more widely recognized comorbidity in RA of cardiovascular disease. Then, I establish that a novel serum biomarker, anti-malondialdehyde-acetaldehyde adduct (MAA) antibody, is associated with the presence of interstitial lung disease (ILD) in RA subjects. Further …
