Allura Red Ac Is A Xenobiotic. Is It Also A Carcinogen?, Lorne J. Hofseth Ph.D., James Hébert Scd, Elizabeth Angela Murphy, Erica Trauner, Athul Vikas, Quinn Harris, Alexander A. Chumanevich

Faculty Publications

Merriam-Webster and Oxford define a xenobiotic as any substance foreign to living systems. Allura Red AC (a.k.a., E129; FD&C Red No. 40), a synthetic food dye extensively used in manufacturing ultra-processed foods and therefore highly prevalent in our food supply, falls under this category. The surge in synthetic food dye consumption during the 70s and 80s was followed by an epidemic of metabolic diseases and the emergence of early-onset colorectal cancer in the 1990s. This temporal association raises significant concerns, particularly given the widespread inclusion of synthetic food dyes in ultra-processed products, notably those marketed toward children. Given its interactions …

Surviving The Rule Of Reason: An Antitrust Analysis Of Employment Noncompetes, Erin Lee Oct 2024

Surviving The Rule Of Reason: An Antitrust Analysis Of Employment Noncompetes, Erin Lee

Fordham Law Review

When the Federal Trade Commission (FTC) issued a rule banning noncompete agreements as unfair methods of competition, it reinvigorated debates regarding the purpose of federal antitrust law. At its core, federal antitrust law seeks to preserve a competitive economy and promote new entry into the marketplace, primarily to protect consumer interest. Under President Biden’s administration, the FTC has increased its efforts to expand the scope of antitrust protection beyond consumer welfare by applying it to other public policy concerns, such as employee mobility. The FTC points to noncompete agreements as detrimental constraints to employees’ economic freedoms. In practice, employment noncompetes …


Bridging The False Certification Gap: Why “Resulting From” In The 2010 Aks Amendment Requires But-For Causation, Alexandra Wildman Oct 2024

Bridging The False Certification Gap: Why “Resulting From” In The 2010 Aks Amendment Requires But-For Causation, Alexandra Wildman

Fordham Law Review

Before 2010, violators of the Anti-Kickback Statute (AKS) could avoid False Claims Act (FCA) liability if claims for items or services borne of their kickback scheme were submitted to federal healthcare programs by a third party. In 2010, as part of the Affordable Care Act (ACA), Congress attempted to close this loophole in the FCA by amending the AKS. Under the amendment’s terms, claims submitted to federal healthcare programs for items or services “resulting from” an AKS scheme are false for the purposes of establishing FCA liability, regardless of who submitted the claims.

Although the amendment widened the FCA liability …

Linkage Between Fuz And Gpr161 Genes Regulates Sonic Hedgehog Signaling During Mouse Neural Tube Development, Sung-Eun Kim, Hyun-Yi Kim, Bogdan J Wlodarczyk, Richard H Finnell

Faculty, Staff and Students Publications

Sonic hedgehog (Shh) signaling regulates embryonic morphogenesis utilizing the primary cilium, the cell's antenna, which acts as a signaling hub. Fuz, an effector of planar cell polarity signaling, regulates Shh signaling by facilitating cilia formation, and the G protein-coupled receptor 161 (Gpr161) is a negative regulator of Shh signaling. The range of phenotypic malformations observed in mice bearing mutations in either of the genes encoding these proteins is similar; however, their functional relationship has not been previously explored. This study identified the genetic and biochemical linkage between Fuz and Gpr161 in mouse neural tube development. Fuz was found to be …

Viability Discrimination Of Bacterial Microbiomes In Home Kitchen Dish Sponges Using Propidium Monoazide Treatment, Christina K Carstens, Joelle K Salazar, Shreela Sharma, Wenyaw Chan, Charles Darkoh

Faculty, Staff and Student Publications

Dish sponges are known to support the proliferation of human bacterial pathogens, yet they are commonly used by consumers. Exposure to foodborne pathogens via sponge use may lead to illness, a serious concern among susceptible populations. The extent of exposure risks from sponge use has been limited by constraints associated with culture-independent or dependent methods for bacterial community characterization. Therefore, five used dish sponges were characterized to evaluate the presence of viable bacterial foodborne pathogens using the novel application of propidium monoazide (PMA) treatment and targeted 16S rRNA gene amplicon sequencing. Select pathogen viability was confirmed using targeted selective enrichment. …

Regulation Of Fibrinogen Synthesis, Dre'von A Dobson, Richard J Fish, Paul S De Vries, Alanna C Morrison, Marguerite Neerman-Arbez, Alisa S Wolberg

Faculty, Staff and Student Publications

The plasma protein fibrinogen is encoded by 3 structural genes (FGA, FGB, and FGG) that are transcribed to mRNA, spliced, and translated to 3 polypeptide chains (Aα, Bβ, and γ, respectively). These chains are targeted for secretion, decorated with post-translational modifications, and assembled into a hexameric “dimer of trimers” (AαBβγ)2. Fully assembled fibrinogen is secreted into the blood as a 340 kDa glycoprotein. Fibrinogen is one of the most prevalent coagulation proteins in blood, and its expression is induced by inflammatory cytokines, wherein circulating fibrinogen levels may increase up to 3-fold during acute inflammatory events. Abnormal …

Faculty, Staff and Student Publications

Spatial transcriptomics (ST) technologies have advanced to enable transcriptome-wide gene expression analysis at submicron resolution over large areas. However, analysis of high-resolution ST is often challenged by complex tissue structure, where existing cell segmentation methods struggle due to the irregular cell sizes and shapes, and by the absence of segmentation-free methods scalable to whole-transcriptome analysis. Here we present FICTURE (Factor Inference of Cartographic Transcriptome at Ultra-high REsolution), a segmentation-free spatial factorization method that can handle transcriptome-wide data labeled with billions of submicron-resolution spatial coordinates and is compatible with both sequencing-based and imaging-based ST data. FICTURE uses the multilayered Dirichlet model …

Sentiment Analysis Of Harry Potter: Exploring Ai Versus Human Interpretation, Xander Newman, Katherine Elkins Oct 2024

Sentiment Analysis Of Harry Potter: Exploring Ai Versus Human Interpretation, Xander Newman, Katherine Elkins

IPHS 200: Programming Humanity

The project starts by examining whether a smaller window size of 5% allows the algorithm to determine cruxes and their sentiment more accurately than the standard 10% window size, using the passages identified by the crux report to assist me. I find that the smaller window size seems to be more accurate for the most part, but this is not always the case. Moreover, regardless of window size, the algorithm struggled with definitively assessing ambivalent sentiment, much like how a reader has their own interpretation of emotionally charged moments. Moreover, using the results of the 5% and 10% window size …
