A Proposed Treatment Of Mixed Connective Tissue Disease By Competitive Inhibition Of Autoantibodies, Thomas Russell

Senior Honors Theses

Mixed Connective Tissue Disease is an autoimmune disease characterized by Raynaud’s phenomenon and arthritis among other symptoms. It is primarily caused by antibodies that target the U1-RNP 70K peptide. The treatment proposed in this paper uses competitive inhibition to prevent the binding of the anti-U1-RNP 70K antibodies with the U1-RNP 70K peptide. A method for testing the designed treatment in silico is proposed using AutoDock Vina docking software.

Choanal atresia is a rare congenital airway malformation that presents a unique surgical challenge for pediatric otolaryngologists. Here we report two classic cases of choanal atresia and examine the surgical approaches to this entity. The first case was a four-day-old female with a history of CHARGE syndrome and bilateral mixed membranous and bony choanal atresia confirmed by a CT scan. After undergoing transnasal endoscopic repair, choanal stents were placed for four weeks, and the patient was seen three months postoperatively and found to be doing well with no respiratory concerns. The second case involved a healthy three-year-old female presenting with …

Classification of myeloid neoplasms with isolated isochromosome i(17q) [17p deletion with inherent monoallelic TP53 loss plus 17q duplication] is controversial. Most cases fall within the WHO unclassifiable myelodysplastic/myeloproliferative neoplasms (MDS/MPN-U) category. The uniformly dismal outcomes warrant better understanding of this entity. We undertook a multi-institutional retrospective study of 92 adult MDS/MPN-U cases from eight institutions. Twenty-nine (32%) patients had isolated i(17q) [MDS/MPN-i(17q)]. Compared to MDS/MPN without i(17q), MDS/MPN-i(17q) patients were significantly younger, had lower platelet and absolute neutrophil counts, and higher frequency of splenomegaly and circulating blasts. MDS/MPN-i(17q) cases showed frequent bilobed neutrophils (75% vs. 23%; P = 0.03), hypolobated …

Antibodies that target immune checkpoint proteins such as programmed cell death protein 1, programmed death ligand 1, and cytotoxic T-lymphocyte-associated antigen 4 in human cancers have achieved impressive clinical success; however, a significant proportion of patients fail to respond to these treatments. Galectin-9 (Gal-9), a β-galactoside-binding protein, has been shown to induce T-cell death and facilitate immunosuppression in the tumor microenvironment by binding to immunomodulatory receptors such as T-cell immunoglobulin and mucin domain-containing molecule 3 and the innate immune receptor dectin-1, suggesting that it may have potential as a target for cancer immunotherapy. Here, we report the development of two …

Targeting Protein Degradation To Uncover Novel Oncoprotein Drivers Of Acute Leukemia, Fatemeh Keramatnia

Theses and Dissertations (ETD)

Acute Lymphoblastic Leukemia (ALL), the most common childhood cancer and the second most common acute leukemia in adults, arises from clonal expansion of undifferentiated lymphoid precursor cells in bone marrow. Despite the extensive knowledge on its cytogenetic and molecular biology, ALL treatment remains highly challenging especially after relapse. Conventional chemotherapy has shown significant improvement in overall survival rates of pediatric patients up to 90%, however, treatment failure due to ALL relapse occurs in 15-20% of the cases. On the other hand, adults and elderly patients with ALL are considered difficult to treat populations with the 5-year overall survival of 30–40%. …

Predictors Of Hyperkalemia And Outcomes Of Dyskalemia In Us Veterans With Advanced Chronic Kidney Disease Transitioning To Dialysis, Ankur Dashputre

Theses and Dissertations (ETD)

Background: The kidneys play a crucial role in maintaining homeostasis of serum potassium levels (K+). Patients with advanced chronic kidney disease (CKD) are at a higher risk of experiencing dyskalemia events (i.e. hyper- and hypokalemia; especially the former) and thus future adverse outcomes. Currently, there is a dearth of literature on prediction models for hyperkalemia and the effects of dyskalemia on outcomes such as incidence of ischemic stroke and short-term hospital/emergency room (ER) utilization in an advanced CKD population transitioning to dialysis. Objectives: Using a nationally representative sample of US veterans with advanced CKD transitioning to dialysis, in the pre-dialysis …

Tatton-Brown-Rahman syndrome (TBRS) is an overgrowth disorder caused by germline heterozygous mutations in the DNA methyltransferase DNMT3A. DNMT3A is a critical regulator of hematopoietic stem cell (HSC) differentiation and somatic DNMT3A mutations are frequent in hematologic malignancies and clonal hematopoiesis. Yet, the impact of constitutive DNMT3A mutation on hematopoiesis in TBRS is undefined. In order to establish how constitutive mutation of DNMT3A impacts blood development in TBRS we gathered clinical data and analyzed blood parameters in 18 individuals with TBRS. We also determined the distribution of major peripheral blood cell lineages by flow cytometric analyses. Our analyses revealed non-anemic macrocytosis, …

The Role Of Palmitoleic Acid In Regulating Hepatic Gluconeogenesis Through Sirt3 In Obese Mice, Xin Guo, Xiaofan Jiang, Keyun Chen, Qijian Liang, Shixiu Zhang, Juan Zheng, Xiaomin Ma, Hongmei Jiang, Hao Wu, Qiang Tong

Faculty, Staff and Students Publications

Hepatic gluconeogenesis is a crucial process to maintain glucose level during starvation. However, unabated glucose production in diabetic patients is a major contributor to hyperglycemia. Palmitoleic acid is a monounsaturated fatty acid (16:1n7) that is available from dietary sources. Palmitoleic acid exhibits health beneficial effects on diabetes, insulin resistance, inflammation, and metabolic syndrome. However, the mechanism by which palmitoleate reduces blood glucose is still unclear. SIRT3 is a key metabolism-regulating NAD+-dependent protein deacetylase. It is known that fasting elevates the expression of SIRT3 in the liver and it regulates many aspects of liver’s response to nutrient deprivation, such as fatty …

Alzheimer's And Patient Caregiver Burnout: A Review Of The Literature, Madeline Hekeler

James Madison Undergraduate Research Journal (JMURJ)

The term “silent epidemic” is fitting for Alzheimer’s disease (AD), as its negative impact is widely felt but rarely discussed. Burnout among AD caregivers has become an epidemic of its own as caregivers experience an increase in health risks, stress, and financial burden. This literature review focuses on caregiver burnout and how imperative it is that caregivers are better supported in their role. Researchers have developed instruments to assess and intervene in caregiver burnout that have shown effectiveness among caregivers and their families.Nevertheless, further longitudinal research is warranted regarding more effective interventions, including stress management and social support mechanisms.

METHODS: Data from a multicenter retrospective cohort study of neonates with sTOF were merged with administrative data to compare total costs and …

What Should Patients Know About Self Blood Pressure Measurement? A Review Article, Sau-Nga Fu

Journal of the Hong Kong College of Cardiology

Many people measure their blood pressure (BP) outside doctors’ offices with a common goal of concerning their health status. Self-BP monitoring devices are widely accessible as health care products or available in different community institutes. Patients often seek their doctors’ advice on their BP readings in our daily practice. Current international guidelines recommend that correct self-BP measurement with validated devices can enhance patients’ self-management and drug compliance, improving overall BP control. While most of the clinicians were supportive of their patients’ efforts, they were also concerned about the validity and reliability of the out-of-office BP readings. How can we effectively …
