Considering Vaccination Status, Govind Persad

UC Law Journal

This Article examines whether policies—sometimes termed “vaccine mandates” or “vaccine requirements”— that consider vaccination status as a condition of employment, receipt of goods and services, or educational or other activity for participation are legally permitted, and whether such policies may even sometimes be legally required. It does so with particular reference to COVID-19 vaccines.

Part I explains the legality of private actors, such as employers or private universities, considering vaccination status, and concludes that such consideration is almost always legally permissible unless foreclosed by specific state legislation. Part II examines the consideration of vaccination status by state or federal policy. …

Engineering A Microbiosphere To Clean Up The Ocean – Inspiration From The Plastisphere, Khulood A. Alnahdi, Laila W. Alali, Mezna K. Suwaidan, M. Kalim Akhtar

All Works

Plastic is a ubiquitous material that has become an essential part of our lives. More than one hundred million tons of plastic has accumulated in the world’s oceans as a result of poor waste management. This plastic waste gradually fragments into smaller pieces known as microplastics and nanoplastics. These small plastic particles can cause significant damage to marine ecosystems, and negatively impact human health. According to a recent review of international patents, the majority of ocean-cleaning inventions are limited to microplastics larger than 20 μm. Furthermore, such technologies are ineffective for nanoplastics, which measure less than 1000 nm, or even …

Adjuvants are essential components of subunit vaccines added to enhance immune responses to antigens through immunomodulation. Very few adjuvants have been approved for human use by regulatory agencies due to safety concerns. Current subunit vaccine adjuvants approved for human use are very effective in promoting humoral immune responses but are less effective at promoting T-cell immunity. In this study, we evaluated a novel pure enantio-specific cationic lipid 1,2-dioleoyl-3-trimethylammonium-propane (R-DOTAP) as an immunomodulator for subunit vaccines capable of inducing both humoral- and cellular-mediated immunity. Using recombinant protein antigens derived from SARS-CoV2 spike or novel computationally optimized broadly reactive influenza antigen (COBRA) …

BACKGROUND: Mammalian cells have developed multiple intracellular mechanisms to defend against viral infections. These include RNA-activated protein kinase (PKR), cyclic GMP-AMP synthase and stimulation of interferon genes (cGAS-STING) and toll-like receptor-myeloid differentiation primary response 88 (TLR-MyD88). Among these, we identified that PKR presents the most formidable barrier to oncolytic herpes simplex virus (oHSV) replication in vitro.

METHODS: To elucidate the impact of PKR on host responses to oncolytic therapy, we generated a novel oncolytic virus (oHSV-shPKR) which disables tumor intrinsic PKR signaling in infected tumor cells.

RESULTS: As anticipated, oHSV-shPKR resulted in suppression of innate antiviral immunity and improves virus …

Immunotherapy efficacy is limited in melanoma, and combinations of immunotherapies with other modalities have yielded limited improvements but also adverse events requiring cessation of treatment. In addition to ineffective patient stratification, efficacy is impaired by paucity of intratumoral immune cells (itICs); thus, effective strategies to safely increase itICs are needed. We report that dietary administration of l-fucose induces fucosylation and cell surface enrichment of the major histocompatibility complex (MHC)-II protein HLA-DRB1 in melanoma cells, triggering CD4+ T cell-mediated increases in itICs and anti-tumor immunity, enhancing immune checkpoint blockade responses. Melanoma fucosylation and fucosylated HLA-DRB1 associate with intratumoral T cell abundance …

Paxlovid-Induced Tacrolimus Toxicity In The Treatment Of Covid-19: A Case Report., Stephanie Michael, Rachel Heilbronner, Christopher M Lloyd, Howard W Levitin

Pharmacy Articles

Paxlovid^TM (nirmaltrelvir/ritonavir) received emergency use authorization from the Food and Drug Administration (FDA) in December 2021 to treat coronavirus disease 2019 (COVID-19). Given the actions of Paxlovid on cytochrome P450-3A4 (CYP3A4) enzymes, it is imperative to check for potential drug-drug interactions before prescribing. We describe a case in which the common emergency department presentation of generalized weakness was found to be caused by interactions between Paxlovid and a patient's home medications resulting in tacrolimus toxicity.

Waterfowl Recently Infected With Low Pathogenic Avian Influenza Exhibit Reduced Local Movement And Delayed Migration, Claire S. Teitelbaum, Michael L. Casazza, Fiona Mcduie, Susan E.W. De La Cruz, Cory T. Overton, Laurie A. Hall, Elliott L. Matchett, Joshua T. Ackerman, Jeffery D. Sullivan, Andrew M. Ramey, Diann J. Prosser

Faculty Research, Scholarly, and Creative Activity

Understanding relationships between infection and wildlife movement patterns is important for predicting pathogen spread, especially for multispecies pathogens and those that can spread to humans and domestic animals, such as avian influenza viruses (AIVs). Although infection with low pathogenic AIVs is generally considered asymptomatic in wild birds, prior work has shown that influenza-infected birds occasionally delay migration and/or reduce local movements relative to their uninfected counterparts. However, most observational research to date has focused on a few species in northern Europe; given that influenza viruses are widespread globally and outbreaks of highly pathogenic strains are increasingly common, it is important …

Synthesis Of Fluoroorganics And Applications Of Novel Fluorinated Building Blocks, Wei Wei

Dissertations, Theses, and Capstone Projects

Diastereoselectivity of fluorination of a carbanion alpha to a sulfone in enantiomerically pure N-Boc protected (R)- and (S)-2,2-dimethyl-4-((arylsulfonyl)methyl)oxazolidines has been studied. Fluorination proceeded with good to excellent diastereoselectivity, which was base-dependent and was highest with lithium diisopropylamide (LDA). Diastereoselectivity also depended on the aryl moiety of the aryl sulfone and was highest with benzothiazole-derived sulfones. Under basic conditions, epimerization at the C–F stereogenic center alpha to the sulfone has been achieved for the first time and proceeded with good to excellent diastereoselectivity, which was highest in the case of a benzothiazole sulfone and with a lithium base. …

Tgf-B Signaling Mechanisms In Caenorhabditis Elegans Response To Bacterial Pathogens, Emma J. Ciccarelli

Dissertations, Theses, and Capstone Projects

When exposed to infection, the nematode C. elegans mounts an innate immune response through secretion of antimicrobial peptides (AMPs). Different signaling pathways in the worm regulate release of these AMPs. One highly conserved pathway is the C. elegans BMP like pathway – regulated by the ligand DBL-1. The DBL-1 pathway is noted for its significant role in development but has also been shown to regulate many post-developmental processes within the worm, including the immune response. We are interested in determining how DBL-1 signaling can mediate a response specific to immunity, separate from its other functions in the worm. Through survival …
