Predation Of Aegaeobuthus Nigrocinctus (Ehrenberg, 1828) (Scorpiones: Buthidae) By A Middle East Black Tarantula, Chaetopelma Olivaceum (C. L. Koch, 1841) (Araneae: Theraphosidae) In Lebanon, Rami Khashab Sep 2025

Predation Of Aegaeobuthus Nigrocinctus (Ehrenberg, 1828) (Scorpiones: Buthidae) By A Middle East Black Tarantula, Chaetopelma Olivaceum (C. L. Koch, 1841) (Araneae: Theraphosidae) In Lebanon, Rami Khashab

Euscorpius

I report the first documented case of the buthid scorpion Aegaeobuthus nigrocinctus (Ehrenberg, 1828) serving as prey for the tarantula Chaetopelma olivaceum (C. L. Koch, 1841) in Lebanon. The observation was made during a nocturnal survey in the Mount Lebanon region. The case contributes to the limited records of tarantula predation on scorpions and underscores the role of prey-predator size asymmetry in facilitating high-risk predation among arachnids.

The Italian Colony Of São Paulo: Race, Class, And Cultural Capital In Brazil, Giulia Riccò

Race & Ethnic Studies

WINNER, 2024 ALDO AND JEANNE SCAGLIONE PUBLICATION AWARD FOR A MANUSCRIPT IN ITALIAN LITERARY STUDIES, MODERN LANGUAGES ASSOCIATION

Introduces a way to study migration that privileges literary analysis over and against sociological data and insists on the importance of culture in the production of political identities

This book argues that Italians first became racialized as white in São Paulo, Brazil, at the turn of the twentieth century. Whereas Italians in the United States struggled with xenophobia and were often not fully acknowledged as white, in São Paulo, due to a series of social, economic, and cultural fac­tors, Italians became closely …

Psma-1-Dota Potentially For Effective Targeted Radioligand Therapy Of Prostate Cancer, Xinning Wang, Olga Sergeeva, Maxim Sergeev, Lifang Zhang, Zoey Lockwood, Zhenghong Lee, James P. Basilion

Faculty Scholarship

Purpose: While PSMA-targeted radioligand therapy (RLT) has shown remarkable efficacy for treating end-stage prostate cancer, the α-emitting RLT often results in severe salivary gland toxicity, limiting its use. Various strategies to mitigate this side effect have been attempted with limited success. Accordingly, this study introduced a new PSMA-targeting ligand with more favorable binding characteristics than the existing ligands. Procedures: The binding affinity of PSMA-1-DOTA to PSMA was compared with that of PSMA-11 and PSMA I&T. Comparison of uptake in the salivary glands, kidneys and PC3pip tumor cells in the xenograft mouse models between [⁶⁸Ga]Ga-PSMA-1-DOTA, [⁶⁸Ga]Ga-PSMA-11 and [⁶⁸Ga]Ga-PSMA I&T was conducted …

Can Corporate Law Wake Up Disney After Biting The Enchanted Apple Of Wokeness: The Politicization Of Disney And Corporate Law’S Weak Response, Brian M. Mccall Sep 2025

Can Corporate Law Wake Up Disney After Biting The Enchanted Apple Of Wokeness: The Politicization Of Disney And Corporate Law’S Weak Response, Brian M. Mccall

The Business, Entrepreneurship & Tax Law Review

Corporations that are household names for American consumers have been in the news for alienating their customers and segments of the public by embroiling their companies in controversial political issues. Target, Anheuser-Busch, and Disney are three prominent examples of companies in the news for putting their foot on politically sensitive issues. As Ryan Newman has explained, the issues raised by these events demonstrate an extensive political activism by American corporations that not only spend billions of dollars on political causes unrelated to their business, but also take actions and political stances on matters wholly unrelated to their products or markets, …

Faculty Research 2025

PURPOSE: Mutations in the myocilin (MYOC) gene cause elevated intraocular pressure and glaucoma. To better understand the factors influencing susceptibility to glaucoma, we studied the MYOC mutation (MYOCY437H).

METHODS: We characterized ocular phenotypes in Tg-MYOCY437H mice on nine different mouse strain backgrounds.

RESULTS: No glaucoma-related phenotypes were observed. We detected neither elevated intraocular pressure (daytime readings) nor optic nerve degeneration differences between wild type (WT) and Tg-MYOCY437H mice. This included an absence of Tg-MYOCY437H-induced phenotypes on a mixed B6SJL background that best reflected the original publications with this strain. We confirmed that this result was not due to an absence …

The outflow of 'dirty' brain fluids from the glymphatic system drains via the meningeal lymphatic vessels to the lymph nodes in the neck, primarily the deep cervical lymph nodes (dcLN). However, it is unclear whether dcLN drainage is essential for normal cerebral homeostasis. Using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and computational fluid dynamics, we studied the impact of long-term mechanical stress from compromised dcLN drainage on brain solute and fluid outflow in anesthetized rats. We found that in young, but not middle-aged, rats, impairment of dcLN drainage was linked to moderately increased intracranial pressure and the emergence of extracranial …


Wine Unwelcome: The Constitutional Contours Of Wine Regulation, Alexander Fallone Sep 2025

Wine Unwelcome: The Constitutional Contours Of Wine Regulation, Alexander Fallone

Brooklyn Journal of Corporate, Financial & Commercial Law

Wine retail shops face a dizzying labyrinth of state laws that severely restrict their ability to ship wine to out-of-state consumers. While the dormant Commerce Clause would normally strike down laws that impose restrictions on interstate commerce, wine (and alcoholic beverages) must contend with Section Two of the Twenty-first Amendment, which gives the states control over the importation and distribution of wine intending to be consumed within their borders. Court of Appeals cases interpreting Supreme Court precedent on the tension between the dormant Commerce Clause and Section Two have practically stripped the dormant Commerce Clause of any power. This Note …

Department of Communication Faculty Publications

Nicknames in sports can serve a wide range of social and semantic functions. Assigning nicknames to athletes and teams can allow fans to identify with them. Such names can also become symbolic resources that fans and teams turn to when asserting their identity. Nicknames in sports come to convey varied meanings and interpretations understood within a set of contextual properties. This paper fills an empirical gap and investigates nicknames of national sports teams used in Southeast Asia. The investigative focus is on the nicknames of the Philippines men’s and women’s national football teams. Employing Leslie and Skipper’s socio-onomastic framework, this …

School of Nursing and Midwifery

University Of Plymouth, Plymouth, UKPeople living with obesity have a greater chance of developingcomplications during pregnancy and are over-represented inmaternal mortality data relating to both direct and indirect causesduring pregnancy and up to a year after the birth of their child. Inaddition, epigenetic influences result in metabolic changes inoffspring of people living with obesity leading to a greater chanceof them experiencing long-term health consequences. In view ofthese health concerns, people living with obesity are advised to loseweight in the preconception period, before becoming pregnant.Sustained weight loss, however, can be difficult to achieve, andpeople do not always seek preconception advice.

The glycerol-3-phosphate (G-3-P) pathway is central to the synthesis of triacylglycerols (TAGs) and glycerophospholipids, essential for membrane biogenesis and lipid storage. The first and rate-limiting step in this pathway is catalyzed by glycerol-3-phosphate acyltransferases (GPATs), with microsomal GPAT3 and GPAT4 being evolutionarily conserved and predominant in most tissues. While previous studies have implicated Calcineurin B homologous protein 1 (CHP1) as a cofactor for GPAT4, the broader role of CHP1 in regulating microsomal GPATs and TAG biosynthesis remains unclear. Here, we demonstrate that CHP1 is a critical regulator of both GPAT3 and GPAT4, essential for their stability, enzymatic activity, and lipid …

The MAPK pathway can drive resistance in highly aggressive breast cancers. Our previous work showed that the MEK inhibitor (MEKi) AZD6244 (selumetinib) prevented lung metastasis in a breast cancer xenograft model. In clinical studies, MEKis as single agents have had only modest activity against solid tumors due to the onset of resistance. Using synthetic lethality siRNA screening, we identified myeloid cell leukemia-1 (MCL-1) as a potential contributor to AZD6244 resistance. We hypothesized that MCL-1 promotes MEKi resistance in highly aggressive breast cancers and that MCL-1 inhibition overcomes AZD6244 resistance. We established two AZD6244-resistant cell lines: MDA-MB-231-R (triple-negative breast cancer) and …

This pilot study presents a sensor–actuator setup designed to evaluate tissue deformation in Atlantic Salmon (Salmo salar) during needle insertion. The system integrates three types of low-cost, commercially available force sensors to capture force profiles and identify biomechanical events associated with tissue layer transitions. Controlled insertions were performed on a deceased specimen, and the resulting force data were analyzed to quantify insertion dynamics and estimate tissue deformation. A simulation model based on the recorded force values was developed to calculate stress distribution and deformation, which ranged from 0.001 µm to 8.4 µm and from 0.3 N/m2 to 4.9 N/m2, respectively. …

Ferroptosis, an iron-dependent form of cell death, holds promise for cancer therapy. However, the intricate link between ferroptosis and oncogenic mutations remains unclear. Here we show that SMARCA4, a well-established tumour suppressor whose deficiency is associated with poor prognosis and resistance to treatments, sensitizes non-small cell lung cancer (NSCLC) cells to ferroptosis. Mechanistically, SMARCA4 promotes chromatin accessibility and expression of ALDH16A1. Surprisingly, ALDH16A1 lacks ALDH enzymatic activity, but binds to the anti-ferroptotic oxidoreductase thioredoxin (TXN), facilitating its translocation to the lysosome and subsequent degradation. Meanwhile, ALDH16A1 directly inhibits TXN's oxidoreductase function by occluding its active site. We also show that …

The ataxia telangiectasia and RAD3-related (ATR) kinase functions with ataxia telangiectasia-mutated (ATM) kinase as a modulator of DNA damage response (DDR). We assessed the antitumor effects of the ATR inhibitor elimusertib (BAY-1895344) in patient-derived xenograft (PDX) models with DDR alterations. Antitumor activity was assessed by change in tumor volume (TV) from baseline. Responses were categorized as follows: partial response (PR), ≥30% decrease in TV; ≥20% increase in TV, progressive disease; and non-PR/progressive disease, stable disease (SD). Event-free survival was defined as time for tumor doubling (EFS-2). Of 21 PDX models tested, 11 had significant prolongation of EFS-2 with elimusertib monotherapy. …

Biological Sciences Faculty Publications and Presentations

Ipomoeassin F (Ipom-F) is a natural compound that exhibits a potent cytotoxic effect on triple-negative breast cancer (TNBC) cells. The mechanism underlying this selective potency remains unclear. To elucidate this mechanism, we analyzed the proteome profiles of the TNBC MDA-MB-231 cells after exposure to Ipom-F at different time points and increasing doses using a quantitative proteomic method. Our proteomic data demonstrate that the major effect of Ipom-F on MDA-MB-231 cells is the inhibition of membrane and secreted protein expression. These findings align with the recently uncovered molecular mechanism of action of Ipom-F, which binds to Sec61-alpha and inhibits the cotranslational …

Background: Mitis group non-pneumococcal streptococci (MGNPS), specifically Streptococcus mitis, Streptococcus infantis and Streptococcus oralis, have recently been shown to cause pneumonia and/or bacteremia. These organisms often have capsular (cps) operons resembling those in pneumococci, and some express cps-generated polysaccharides that antigenically cross-react with pneumococcal capsular serotypes. But, to date, a series of MGNPS isolates has not been studied by electron microscopy (EM) for the presence of a capsule.

Methods: We studied 21 MGNPS; 11 were isolated from sputum and determined to have caused pneumonia, 3 were isolated from blood, and 7 were commensal isolates cultured …
