Covid-19 Vaccination And Alcohol Consumption: Justification Of Risks, 2023 Old Dominion University
Covid-19 Vaccination And Alcohol Consumption: Justification Of Risks, Pavel A. Solopov
Since the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, pharmaceutical companies and research institutions have been actively working to develop vaccines, and the mass roll-out of vaccinations against COVID-19 began in January 2021. At the same time, during lockdowns, the consumption of alcoholic beverages increased. During the peak of vaccination, consumption remained at high levels around the world, despite the gradual relaxation of quarantine restrictions. Two of the popular queries on search engines were whether it is safe to drink alcohol after vaccination and whether this will affect the effectiveness of vaccines. Over the past two …

Daclizumab (Zinbryta®): An Emerging Therapy For The Treatment Of Relapsing-Remitting Multiple Sclerosis, Morgan Homan, Sunitha Jones, Michaela Louden, Molly Wheeler, Anh Dao Le, Lindsey Peters
Pharmacy and Wellness Review
Multiple sclerosis (MS) is an autoimmune disorder of the central nervous system characterized by the deterioration of the myelin sheath, causing axonal damage which leads to debilitating symptoms. Most therapies for the treatment of MS, including daclizumab, primarily target relapsing-remitting multiple sclerosis (RRMS), a form of MS where patients experience periods of exacerbated symptoms as well as intermittent periods of remission. Daclizumab is a humanized monoclonal antibody that is administered as a once monthly subcutaneous injection. The SELECT trilogy of trials have been instrumental in providing safety and efficacy data for daclizumab. The DECIDE study was the first randomized controlled …
May-Thurner Compressive Syndrome Unmasked By Rapid Weight Loss, 2021 Brandon Regional Hospital
May-Thurner Compressive Syndrome Unmasked By Rapid Weight Loss, Hesham A. Hassan, Jan-Paul Sambataro, James C. Abraham
HCA Healthcare Journal of Medicine
May-Thurner Syndrome (MTS) is an anatomical syndrome characterized by a predisposition to clot formation when there is compression of the left iliac vein by the right iliac artery. In this case, we discuss an atypical presentation of MTS in a young male after rapid weight loss. The patient was admitted for an unprovoked massive proximal deep vein thrombosis (DVT) after a two-hundred-pound weight loss during the preceding six-month period. Treatment involved mechanical thrombectomy by interventional radiology, initiation of apixaban and recommended follow up with vascular surgery for angioplasty instead of immediate stent placement.
Bleeding Disorder Referrals To Hematology Clinic: A Single Institution Experience, 2021 Children's Mercy Kansas City
Bleeding Disorder Referrals To Hematology Clinic: A Single Institution Experience, Zuri Hudson
Background: Our center receives hundreds of referrals yearly for bleeding disorder evaluation both due to bleeding symptoms and secondary to routine preoperative laboratory testing. The evaluation for a bleeding disorder can be challenging due to the wide variability of symptoms as well as the need for accurately interpreting lab results. Bhasin et al showed that 4% of patients referred to hematology based on a preoperative coagulation evaluation had a clinically relevant bleeding disorder. Currently there is little published about the referral patterns to pediatric hematology and the outcomes of these referrals.
Objectives/Goal: To characterize our hematology referrals for bleeding disorder …

Extracellular vesicles are thought to facilitate pathogen transmission from arthropods to humans and other animals. Here, we reveal that pathogen spreading from arthropods to the mammalian host is multifaceted. Extracellular vesicles from Ixodes scapularis enable tick feeding and promote infection of the mildly virulent rickettsial agent Anaplasma phagocytophilum through the SNARE proteins Vamp33 and Synaptobrevin 2 and dendritic epidermal T cells. However, extracellular vesicles from the tick Dermacentor andersoni mitigate microbial spreading caused by the lethal pathogen Francisella tularensis. Collectively, we establish that tick extracellular vesicles foster distinct outcomes of bacterial infection and assist in vector feeding by acting …
Effect Of He Plasma Jet Versus Surface Plasma On The Metabolites Of Acute Myeloid Leukemia Cells, 2021 Old Dominion University
Effect Of He Plasma Jet Versus Surface Plasma On The Metabolites Of Acute Myeloid Leukemia Cells, Dehui Xu, Ning Ning, Yujing Xu, Wenjie Xia, Hai-Lan Chen, Michael G. Kong
Cold atmospheric plasma, including plasma jet and surface plasma, can promote the apoptosis of cancer cells without causing significant damage to surrounding normal cells, which was hopeful to be applied to the clinical cancer therapy. However, experimental plasma devices used directly to clinical experiments has challenges in technology and methods, especially the difference in killing tumor cells efficiency of these two common plasma sources. Therefore, it is great necessity to explore the differences in treating tumors between different plasma sources. This paper achieved good killing efficiency by using two kinds of cold atmospheric plasma generating devices, namely plasma jet and …

College of Arts & Sciences Senior Honors Theses
The presence of pathogens in the human body influences the expression of pro-inflammatory cytokines by activated immune cells. These cytokines, and other factors, regulate osteoclastogenesis and osteoclast activity. Through experimental osteoimmunology, interactions between the inflammatory response and bone cell physiology may provide insight into how immune processes can be translated into the lesions or abnormalities observed in the osteological record. In this research, our objective was to determine if the cytokines produced by activated immune cells increase osteoclastogenesis and osteoclast activity. To evaluate this hypothesis, we used two main protocols, one for immune activation and one for osteoclastogenesis, that utilized …

Nuclear Magnetic Resonance Solution Structure And Functional Behavior Of The Human Proton Channel, Monika Bayrhuber, Innokentiy Maslennikov, Witek Kwiatkowski, Alexander Sobol, Christoph Wierschem, Cédric Eichmann, Lukas Frey, Roland Riek
Pharmacy Faculty Articles and Research
The human voltage-gated proton channel [Hv1(1) or VSDO(2)] plays an important role in the human innate immune system. Its structure differs considerably from those of other cation channels. It is built solely of a voltage-sensing domain and thus lacks the central pore domain, which is essential for other cation channels. Here, we determined the solution structure of an N- and C-terminally truncated human Hv1 (Δ-Hv1) in the resting state by nuclear magnetic resonance (NMR) spectroscopy. Δ-Hv1 comprises the typical voltage-sensing antiparallel four-helix bundle (S1–S4) preceded by an amphipathic helix (S0). The solution structure corresponds to an intermediate …
Control Of Antiviral Innate Immune Response By Protein Geranylgeranylation, 2019 Duke University
Control Of Antiviral Innate Immune Response By Protein Geranylgeranylation, Shigao Yang, Zhaozhao Jiang, Katherine A. Fitzgerald, Donghai Wang
Katherine A. Fitzgerald
The mitochondrial antiviral signaling protein (MAVS) orchestrates host antiviral innate immune response to RNA virus infection. However, how MAVS signaling is controlled to eradicate virus while preventing self-destructive inflammation remains obscure. Here, we show that protein geranylgeranylation, a posttranslational lipid modification of proteins, limits MAVS-mediated immune signaling by targeting Rho family small guanosine triphosphatase Rac1 into the mitochondria-associated endoplasmic reticulum (ER) membranes (MAMs) at the mitochondria-ER junction. Protein geranylgeranylation and subsequent palmitoylation promote Rac1 translocation into MAMs upon viral infection. MAM-localized Rac1 limits MAVS' interaction with E3 ligase Trim31 and hence inhibits MAVS ubiquitination, aggregation, and activation. Rac1 also facilitates …

Interferons (IFNs) are critical determinants in immune-competence and autoimmunity, and are endogenously regulated by a low-level constitutive feedback loop. However, little is known about the functions and origins of constitutive IFN. Recently, lipopolysaccharide (LPS)-induced IFN was implicated as a driver of necroptosis, a necrotic form of cell death downstream of receptor-interacting protein (RIP) kinase activation and executed by mixed lineage kinase like-domain (MLKL) protein. We found that the pre-established IFN status of the cell, instead of LPS-induced IFN, is critical for the early initiation of necroptosis in macrophages. This pre-established IFN signature stems from cytosolic DNA sensing via cGAS/STING, and …
Role Of T-Bet In Production Of Immunoglobulin Isotypes In An Influenza Setting, 2019 University of Central Florida
Role Of T-Bet In Production Of Immunoglobulin Isotypes In An Influenza Setting, David Sidhom
Honors Undergraduate Theses
Influenza is one of the most common diseases worldwide, yet the vaccines against influenza are only 35% effective at protecting against infection. Creating a more effective vaccine requires an understanding of the foundation and the factors that contribute to a strong and protective adaptive immune response. T-bet [TBX21] is a transcription factor that plays an instrumental role in the orchestration of the type 1 immune response, which is the specialized response used by the immune system for a cell-mediated response against intracellular pathogens, such as influenza. It has yet to be explored in an influenza setting on the role T-bet …
Immune Checkpoints In Cancer Treatment, 2018 Gettysburg College
Immune Checkpoints In Cancer Treatment, Matthew A. Cherubino
Despite the human immune system, cancer thrives in an extremely hostile environment. Cancer is the second most common cause of death in the U.S. with about 600,000 deaths every year, and cancer is expected to surpass heart disease as the most common cause of death in the U.S. Immune checkpoint inhibitors are a novel and promising therapeutic for treating cancer in its late stages.

The Systemic Quantification Of Immune Cell Populations In Various Murine Models: How Age, Tumor Burden, And Immunotherapy Affect The Immune Response, Kavita Sinha
Honors Scholar Theses
Immunotherapy as a form of cancer treatment has become increasingly popular in the past few decades. Researchers have worked to figure out how to best use the body’s natural defense mechanism, the immune system, to fight off and destroy cancer cells. In particular, the goal has been to manipulate checkpoint blockades such as CTLA-4 and PD-1 in order to take the breaks off of the immune system, allowing for a prolonged immune response to the cancer. This work has led to the development of human versions of anti-CTLA4 antibodies (ipilimumab, tremelimumab) and anti-PD1 antibodies (pembrolizumab and Nivolumab) that are currently …

Immunodeficient R2g2 Mouse Strain Yields Spleens With Unusual Cytoarchitecture And Sympathetic Innervation, Nicholas Mason Britt, Madeleine Kate Miller, Donald B. Hoover Ph.D., John B. Schweitzer M.D.
Appalachian Student Research Forum
The nervous system and immune system contact one another through two-way communication in order to establish and preserve homeostasis. The sympathetic neurotransmitter norepinephrine has an impact on how the immune system responds by affecting regional blood flow and activation of adrenergic receptors on leukocytes. Former studies showed that immune cells are capable of releasing nerve growth factor allowing for the establishment and continuation of sympathetic nerves in targeted tissues. From this gathered information, it was hypothesized that sympathetic nerves would prove to be less frequent in spleens from the immunodeficient R2G2 mouse strain (Envigo) when compared to 129P3/J (129) and …
Wnt Secretion Proteins Modulate Rankl-Induced Expression Of Aire In Thymic Epithelial Cells, 2018 CUNY City College
Wnt Secretion Proteins Modulate Rankl-Induced Expression Of Aire In Thymic Epithelial Cells, Daniel Pollack
Dissertations and Theses
Thymic epithelial cells (TEC) are essential for a proper adaptive immune response by regulating thymocyte development and establishing central tolerance. In the thymus, TECs differentially express Wnt proteins, which activate canonical and non-canonical Wnt signaling pathways. Wnt signaling is thought to regulate cell survival, proliferation, and development although the direct molecular mechanisms in TECs have yet to be elucidated. The inducible inhibition of canonical Wnt signaling with Dkk1 leads to a rapid loss of TEC progenitors as well as a decline in mature Aire-expressing mTECs. Therefore, we explore the role of Wnt ligands potentially responsible for stimulating and/or regulating Wnt …

Improving Type And Screen Specimen Collection Prior To Elective Surgery, Nordx Blood Bank Staff, Haley Pelletier, Suneela Nayak, Stephen Tyzik, Ruth Hanselman
Maine Medical Center
To avoid delays in the availability of compatible blood for elective surgery patients requiring transfusion, a type and screen specimen should be completed at least 24 hours prior to surgery. Baseline metrics in an acute care inpatient blood bank demonstrated a significant number of cases with no type or screen completed.
The objective of this KPI was to prevent any delays in providing compatible blood products to scheduled surgical patients. Several internal and external system issues were identified as a result of a root cause analysis and a number of actions were initiated.
Outcomes have been positive. Data collection post …
