Nondelegation And The Legislative Versus Administrative Exactions Divide: Why Legislatively Imposed Exactions Do Not Require A More Searching Standard Of Review, Hunter Dominick

Fordham Law Review

As the United States continues to grow and urbanize, local governments have tried to manage this growth to mitigate the external impacts that new developments can cause. One method by which state and local governments seek to control growth within their borders is by imposing conditions on the issuance of building permits—otherwise known as exactions. Exactions, however, face federal constitutional limits under the Takings Clause of the Fifth Amendment, which applies to state and local governments through the Fourteenth Amendment.

In Nollan v. California Coastal Commission and Dolan v. City of Tigard, the U.S. Supreme Court restricted exactions in …

Background

Observing medication ingestion through self-recorded videos (video directly observed therapy [VDOT]) has been shown to be a cost-effective alternative to in-person directly observed therapy (DOT) for monitoring adherence to treatment for tuberculosis disease. VDOT could be a useful tool to monitor short-course latent tuberculosis infection (LTBI) treatment.

Methods

We conducted a prospective randomized controlled trial comparing VDOT (intervention) and clinic-based DOT (control) among patients newly diagnosed with LTBI who agreed to a once-weekly 3-month treatment regimen of isoniazid and rifapentine. Study outcomes were treatment completion and patient satisfaction. We also assessed costs. Pre- and posttreatment interviews were conducted.

Accurate Characterization Of Binding Kinetics And Allosteric Mechanisms For The Hsp90 Chaperone Inhibitors Using Ai-Augmented Integrative Biophysical Studies, Chao Xu, Xianglei Zhang, Lianghao Zhao, Gennady M. Verkhivker, Fang Bai

Mathematics, Physics, and Computer Science Faculty Articles and Research

The binding kinetics of drugs to their targets are gradually being recognized as a crucial indicator of the efficacy of drugs in vivo, leading to the development of various computational methods for predicting the binding kinetics in recent years. However, compared with the prediction of binding affinity, the underlying structure and dynamic determinants of binding kinetics are more complicated. Efficient and accurate methods for predicting binding kinetics are still lacking. In this study, quantitative structure–kinetics relationship (QSKR) models were developed using 132 inhibitors targeting the ATP binding domain of heat shock protein 90α (HSP90α) to predict the dissociation rate …

Fluorescence Microscopy With Deep Uv, Near Uv, And Visible Excitation For In Situ Detection Of Microorganisms, Noel Case, Nikki Johnston, Jay Nadeau

Physics Faculty Publications and Presentations

We report a simple, inexpensive design of a fluorescence microscope with light-emitting diode (LED) excitation for detection of labeled and unlabeled microorganisms in mineral substrates. The use of deep UV (DUV) excitation with visible emission requires no specialized optics or slides and can be implemented easily and inexpensively using an oblique illumination geometry. DUV excitation (<280 >nm) is preferable to near UV (365 nm) for avoidance of mineral autofluorescence. When excited with DUV, unpigmented bacteria show two emission peaks: one in the near UV ∼320 nm, corresponding to proteins, and another peak in the blue to green range, corresponding to …

Autophagy Is Required For Stem-Cell-Mediated Endometrial Programming And The Establishment Of Pregnancy, Pooja Popli, Ramakrishna Kommagani

Faculty, Staff and Students Publications

Autophagy plays an important role in the normal growth and morphogenesis of a variety of tissues. Its role in uterine maturation, however, is not fully characterized. Recently, we reported that BECN1 (Beclin1)-dependent autophagy, but not apoptosis, is crucial for stem cell-mediated endometrial programming and the establishment of pregnancy in mice. Upon genetic and pharmacological inhibition of BECN1-mediated autophagy, female mice displayed severe endometrial structural and functional defects leading to infertility. Specifically, conditional loss of Becn1 in the uterus induces apoptosis and results in the gradual loss of endometrial progenitor stem cells. Importantly, the restoration of BECN1-driven autophagy, but not apoptosis …

Relevance Of Lymphocyte Proliferation To Pha In Severe Combined Immunodeficiency (Scid) And T Cell Lymphopenia, Roshini S Abraham, Amrita Basu, Jennifer R Heimall, Elizabeth Dunn, Alison Yip, Malika Kapadia, Neena Kapoor, Lisa Forbes Satter, Rebecca Buckley, Richard O'Reilly, Geoffrey D E Cuvelier, Sharat Chandra, Jeffrey Bednarski, Sonali Chaudhury, Theodore B Moore, Hilary Haines, Blachy J Dávila Saldaña, Deepakbabu Chellapandian, Ahmad Rayes, Karin Chen, Emi Caywood, Shanmuganathan Chandrakasan, Mark Thomas Vander Lugt, Christen Ebens, Pierre Teira, Evan Shereck, Holly Miller, Victor Aquino, Hesham Eissa, Lolie C Yu, Alfred Gillio, Lisa Madden, Alan Knutsen, Ami J Shah, Kenneth Desantes, Jessie Barnum, Larisa Broglie, Avni Y Joshi, Gary Kleiner, Jasmeen Dara, Susan Prockop, Caridad Martinez, Talal Mousallem, Joseph Oved, Lauri Burroughs, Rebecca Marsh, Troy R Torgerson, Jennifer W Leiding, Sung Yun Pai, Donald B Kohn, Michael A Pulsipher, Linda M Griffith, Luigi D Notarangelo, Morton J Cowan, Jennifer Puck, Christopher C Dvorak, Elie Haddad

Severe combined immunodeficiency (SCID) is characterized by a severe deficiency in T cell numbers. We analyzed data collected (n = 307) for PHA-based T cell proliferation from the PIDTC SCID protocol 6901, using either a radioactive or flow cytometry method. In comparing the two groups, a smaller number of the patients tested by flow cytometry had < 10% of the lower limit of normal proliferation as compared to the radioactive method (p = 0.02). Further, in patients with CD3+ T cell counts between 51 and 300 cells/μL, there was a higher proliferative response with the PHA flow assay compared to the 3H-T assay (p < 0.0001), suggesting that the method of analysis influences the resolution and interpretation of PHA results. Importantly, we observed many SCID patients with profound T cell lymphopenia having normal T cell proliferation when assessed by flow cytometry. We recommend this test be considered only as supportive in the diagnosis of typical SCID.

Current And Future Perspectives On The Consensus Guideline For Food Protein-Induced Enterocolitis Syndrome (Fpies), Sara Anvari, Melanie A Ruffner, Anna Nowak-Wegrzyn

Faculty, Staff and Students Publications

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE mediated food allergy presenting with delayed onset of projectile vomiting in the absence of cutaneous and respiratory symptoms. The pathophysiology of FPIES remains poorly characterized. The first international consensus guidelines for FPIES were published in 2017 and provided clinicians with parameters on the diagnosis and treatment of FPIES. The guidelines have served as a resource in the recognition and management of FPIES, contributing to an increased awareness of FPIES. Since then, new evidence has emerged, shedding light on adult-onset FPIES, the different phenotypes of FPIES, the recognition of new food triggers, center-specific …

Current anticancer therapies cannot eliminate all cancer cells, which hijack normal arginine methylation as a means to promote their maintenance via unknown mechanisms. Here we show that targeting protein arginine N-methyltransferase 9 (PRMT9), whose activities are elevated in blasts and leukemia stem cells (LSCs) from patients with acute myeloid leukemia (AML), eliminates disease via cancer-intrinsic mechanisms and cancer-extrinsic type I interferon (IFN)-associated immunity. PRMT9 ablation in AML cells decreased the arginine methylation of regulators of RNA translation and the DNA damage response, suppressing cell survival. Notably, PRMT9 inhibition promoted DNA damage and activated cyclic GMP-AMP synthase, which underlies the type …
