Articles

The U.S. regulatory environment is changing rapidly, at the same time that visible and profound impacts of climate change are already being felt throughout the world, and enormous, potentially existential threats loom in the not-so-distant future. What does it mean to think about and practice environmental law in this setting? In this latest in a biannual series of postings and essays, the authors, members of the Environmental Law Collaborative (ELC), have taken on the question of whether environmental law as we currently know it is up to the job of addressing these threats; and, if not, what the path forward …

How Neuroscience Technology Is Changing Our Understanding Of Brain Injury, Vegetative States And The Law, Glenn R. Butterton

Articles

The author examines clinical studies that use neuroscience technology to study patients in Vegetative States. The studies indicate that some of the patients are, in fact, conscious. The author suggests that this finding is a matter of considerable practical importance for the drafting and execution of end-of-life protocols such as Advance Directives and Living Wills. He recommends that statutes, and other guidance used by patients, caregivers, medical institutions, family members and others to draft and interpret such Directives and Wills, be revised or amended to take account of these results.

The Case Against Expanding Defamation Law, Yonathan A. Arbel, Murat Mungan

Articles

It is axiomatic that defamation law protects reputation This proposition"”common sensical pervasive and influential"”is wrong But it is wrong in a very instructive way and a careful examination of its mistaken assumptions carries deep lessons for First Amendment jurisprudence defamation law and the regulation of falsehoods across legal fields brbrThe key fallacy is the failure to recognize that laws not only affect how individuals behave but also how they think Whenever an allegation is made individuals decide whether and how much to trust it based on myriad factors One such factor is the strictness of defamation laws To the extent …

Antebellum And Postbellum Testamentary Transfers In Three Kentucky Counties Symposium: Empirical Analysis Of Wealth Transfer Law, Alberto B. Lopez

Articles

This Article analyzes wills and inventories probated in three Kentucky counties, Boone, Woodford, and Wayne Counties, between 186 and 187. The results of the study show that married women in the three counties generally did not execute wills during the sample period, which is an expected result given the testamentary limitations imposed upon married women by Kentucky law. Despite dual encumbrances imposed by common and statutory law during the sample period, legislative and judicial action before, during, and after the sampled decade illustrates the advance of women's property rights in Kentucky. The Kentucky General Assembly passed a number of private …

The Orphan Drug Act At 35: Observations And An Outlook For The Twenty-First Century, Nicholas Bagley, Benjamin Berger, Amitabh Chandra, Craig Garthwaite

Articles

On the thirty-fifth anniversary of the adoption of the Orphan Drug Act (ODA), we describe the enormous changes in the markets for therapies for rare diseases that have emerged over recent decades. The most prominent example is the fact that the profit-maximizing price of new orphan drugs appears to be greater today than it was in 1983. All else equal, this should reduce the threshold for research and development (R&D) investment in an economically viable product. Further, the small size of patient populations for orphan drugs, together with the increasing prevalence of biologics among orphan drugs, have created a set …

Reputation And Accountability: Another Look At The United Nations’ Response To The Cholera Epidemic In Haiti, Kristina Daugirdas

Articles

The cholera outbreak in Haiti offers a useful case study of reputation as a disciplinarian of international organizations. On the one hand, UN officials and member states alike have emphasized the need to repair the organization’s damaged reputation. On the other hand, the UN secretariat declined to take certain steps that might have averted—or at least mitigated—that reputational damage in the first place. This contribution argues that the United Nations’ response to cholera in Haiti showcases some important limitations and complications of reputation as a disciplinarian. Reputation will function as a less effective disciplinarian of organizations in the context of …

Shadow Health Records Meet New Data Privacy Laws, W. Nicholson Price Ii, Margot E. Kaminski, Timo Minssen, Kayte Spector-Bagdady

Articles

Large sets of health data can enable innovation and quality measurement but can also create technical challenges and privacy risks. When entities such as health plans and health care providers handle personal health information, they are often subject to data privacy regulation. But amid a flood of new forms of health data, some third parties have figured out ways to avoid some data privacy laws, developing what we call “shadow health records”—collections of health data outside the health system that provide detailed pictures of individual health—that allow both innovative research and commercial targeting despite data privacy rules. Now that space …

Class Actions, Indivisibility, And Rule 23(B)(2), Maureen Carroll

Articles

The federal class-action rule contains a provision, Rule 23(b)(2), that authorizes class-wide injunctive or declaratory relief for class-wide wrongs. The procedural needs of civil rights litigation motivated the adoption of the provision in 1966, and in the intervening years, it has played an important role in managing efforts to bring about systemic change. At the same time, courts have sometimes struggled to articulate what plaintiffs must show in order to invoke Rule 23(b)(2). A few years ago, the Supreme Court weighed in, stating that the key to this type of class action is the “indivisible” nature of the remedy the …

Targeting Poverty In The Courts: Improving The Measurement Of Ability To Pay Fines, Meghan M. O'Neil, J.J. Prescott

Articles

Ability-to-pay determinations are essential when governments use money-based alternative sanctions, like fines, to enforce laws. One longstanding difficulty in the U.S. has been the extreme lack of guidance on how courts are to determine a litigant’s ability to pay. The result has been a seat-of-the-pants approach that is inefficient and inaccurate, and, as a consequence, very socially costly. Fortunately, online platform technology presents a promising avenue for reform. In particular, platform technology offers the potential to increase litigant access, reduce costs, and ensure consistent and fair treatment—all of which should lead to more accurate sanctions. We use interviews, surveys, and …

A Review Of The Putative Causal Mechanisms Associated With Lower Macular Pigment In Diabetes Mellitus, Grainne Scanlon, James Loughman, Donal Farrell, Daniel Mccartney

Articles

Macular pigment (MP) confers potent antioxidant and anti-inflammatory effects at the macula, and may therefore protect retinal tissue from the oxidative stress and inflammation associated with ocular disease and ageing. There is a body of evidence implicating oxidative damage and inflammation as underlying pathological processes in diabetic retinopathy. MP has therefore become a focus of research in diabetes, with recent evidence suggesting that individuals with diabetes, particularly type 2 diabetes, have lower MP relative to healthy controls. The present review explores the currently available evidence to illuminate the metabolic perturbations that may possibly be involved in MP’s depletion. Metabolic co-morbidities …

Degradation Kinetics Of Cold Plasma-Treated Antibiotics And Their Antimicrobial Activity, Chaitanya Sarangapani, Dana Ziuzina, Patrice Behan, Daniela Boehm, Brendan F. Gilmore, Patrick J. Cullen, Paula Bourke

Articles

Antibiotics, such as ofloxacin (OFX) and ciprofloxacin (CFX), are often detected in considerable concentrations in both wastewater effluents and surface water. This poses a risk to non-target organisms and to human health. The aim of this work was to study atmospheric cold plasma (ACP) degradation of antibiotics in water and meat effluent and to explore any residual antimicrobial activity of samples submitted to the plasma process. The results revealed that ACP successfully degraded the studied antibiotics and that the reaction mechanism is principally related to attack by hydroxyl radicals and ozone. According to the disk diffusion assay, the activity of …

Forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and diffusion capacity …

The Effect Of Atmospheric Cold Plasma On Bacterial Stress Responses And Virulence Using Listeria Monocytogenes Knockout Mutants, Apurva Patange, Conor O'Byrne, Daniela Boehm, Patrick J. Cullen, Kevin Keener, Paula Bourke

Articles

Listeria monocytogenes is an opportunistic intracellular pathogen commonly associated with serious 16 infections and multiple food-borne outbreaks. In this study, we investigated the influence of 17 atmospheric cold plasma (80 kV, 50 Hz) on L. monocytogenes (EGD-e) and its knockout mutants of 18 sigB, rsbR, prfA, gadD and lmo0799 genes at different treatment time intervals. Further, to ascertain if 19 sub-lethal environmental stress conditions could influence L. monocytogenes survival and growth 20 responses, atmospheric cold plasma (ACP) resistance was evaluated for the cultures exposed to cold 21 (4°C) or acid (pH 4) stress for 1 h. The results demonstrate that …

The Abundance Of Akkermansia Muciniphila And Its Relationship With Sulphated Colonic Mucins In Health And Ulcerative Colitis, Helen Earley, Grainne Earley, Aine Balfe, J. Calvin Coffey, Desmond C. Winter, Ronan O'Connell

Articles

Akkermansia muciniphila utilises colonic mucin as its substrate. Abundance is reduced in ulcerative colitis (UC), as is the relative proportion of sulphated mucin in the mucus gel layer (MGL). It is unknown if these phenomena are related, however reduced sulphated mucins could contribute to reduced abundance, owing to a lack of substrate. The aim of this study was to quantify A. muciniphila within the MGL and to relate these findings with markers of inflammation and the relative proportion of sulphomucin present. Colonic biopsies and mucus brushings were obtained from 20 patients with active UC (AC), 14 with quiescent UC (QUC) …

Dough Properties And Baking Characteristics Of White Bread, As Affected By Addition Of Raw, Germinated And Toasted Pea Flour, Kim A. Millar, Catherine Barry-Ryan, Roisin Burke, Sinead Mccarthy, Eimear Gallagher

Articles

Thermal and non-thermal processing may alter the structure and improve the techno-functional properties of pulses and pulse flours, increasing their range of applications in protein-enhanced foods. The effects of germination and toasting of yellow peas (Pisum sativum) on flour and dough characteristics were investigated. Wheat flour was substituted with raw, germinated and toasted pea flour (30%). The resulting bread-baking properties were assessed. Toasting increased dough water absorption and improved dough stability compared with germinated and raw pea flour (p < 0.05). This resulted in bread loaves with comparable specific volume and loaf density to that of a wheat flour control. Significant correlations between dough rheological properties and loaf characteristics were observed. Addition of pea flours increased the protein content of the breads from 8.4% in the control white bread, to 10.1–10.8% (p < 0.001). Toasting demonstrated the potential to improve the techno-functional properties of pea flour. Results highlight the potential application of pea flour in bread-making to increase the protein content.

A U-Net Deep Learning Framework For High Performance Vessel Segmentation In Patients With Cerebrovascular Disease, Michelle Livne, Jana Rieger, Orhun Utku Aydin, Abdel Aziz Taha, Ela Marie Akay, Tabea Kossen, Jan Sobesky, John D. Kelleher, Kristian Hildebrand, Dietmar Frey, Vince I. Madai

Articles

Brain vessel status is a promising biomarker for better prevention and treatment in cerebrovascular disease. However, classic rule-based vessel segmentation algorithms need to be hand-crafted and are insufficiently validated. A specialized deep learning method—the U-net—is a promising alternative. Using labeled data from 66 patients with cerebrovascular disease, the U-net framework was optimized and evaluated with three metrics: Dice coefficient, 95% Hausdorff distance (95HD) and average Hausdorff distance (AVD). The model performance was compared with the traditional segmentation method of graph-cuts. Training and reconstruction was performed using 2D patches. A full and a reduced architecture with less parameters were trained. We …

The Case Against Expanding Defamation Law, Yonathan A. Arbel, Murat Mungan

Articles

It is considered axiomatic that defamation law protects reputation. This proposition--commonsensical, pervasive, and influential-- is faulty. Underlying this fallacy is the failure to appreciate audience effects: the interaction between defamation law and members of the audience.

Defamation law seeks to affect the behavior of speakers by making them bear a cost for spreading untruthful information. Invariably, however, the law will also affect members of the audience, as statements made in a highly regulated environment tend to appear more reliable than statements made without accountability. Strict defamation law would tend to increase the perceived reliability of statements, which in some cases …

Plasma-Treated Air And Water—Assessment Of Synergistic Antimicrobial Effects For Sanitation Of Food Processing Surfaces And Environment, Uta Schnabel, Oliver Handorf, Kateryna Yarova, Björn Zessin, Susann Zechlin, Diana Sydow, Elke Zellmer, Jörg Stachowiak, Mathias Andrasch, Harald Below, Jörg Ehlbeck

Articles

The synergistic antimicrobial effects of plasma-processed air (PPA) and plasma-treated water (PTW), which are indirectly generated by a microwave-induced non-atmospheric pressure plasma, were investigated with the aid of proliferation assays. For this purpose, microorganisms (Listeriamonocytogenes, Escherichiacoli, Pectobacteriumcarotovorum, sporulatedBacillusatrophaeus) were cultivated as monocultures on specimens with polymeric surface structures. Both the distinct and synergistic antimicrobial potential of PPA and PTW were governed by the plasma-on time (5–50 s) and the treatment time of the specimens with PPA/PTW (1–5 min). In single PTW treatment of the bacteria, an elevation of the reduction factor with increasing treatment time could be observed (e.g., reduction …

High Voltage Atmospheric Cold Air Plasma Control Of Bacterial Biofilms On Fresh Produce, Apurva Patange, D. Boehm, Dana Ziuzina, Patrick J. Cullen, Brendan Gilmore, Paula Bourke

Articles

Atmospheric cold plasma (ACP) offers great potential for decontamination of food borne pathogens. This study examined the antimicrobial efficacy of ACP against a range of pathogens of concern to fresh produce comparing planktonic cultures, monoculture biofilms (Escherichia coli, Salmonella enterica, Listeria monocytogenes, Pseudomonas fluorescens) and mixed culture biofilms (Listeria monocytogenes and Pseudomonas fluorescens). Biotic and abiotic surfaces commonly occurring in the fresh food industry were investigated. Microorganisms showed varying susceptibility to ACP treatment depending on target and process factors. Bacterial biofilm populations treated with high voltage (80 kV) ACP were reduced significantly (p <  0.05) in both mono- and mixed species biofilms after 60 s of treatment and yielded non-detectable levels after extending treatment time to 120 s. However, an extended time was required to reduce the challenge mixed culture biofilm of L. monocytogenes and P. fluorescens inoculated on lettuce, which was dependent on biofilm formation conditions and substrate. Contained treatment for 120 s reduced L. monocytogenes and P. fluorescens inoculated as mixed cultures on lettuce (p <  0.05) by 2.2 and 4.2 Log10 CFU/ml respectively. When biofilms were grown at 4 °C on lettuce, there was an increased resistance to ACP treatment by comparison with biofilm grown at temperature abuse conditions of 15 °C. Similarly, L. monocytogenes and P. fluorescens exposed to cold stress (4 °C) for 1 h demonstrated increased tolerance to ACP treatment compared to non-stressed cells. These finding demonstrates that bacterial form, mono versus mixed challenges as well as environmental stress conditions play an important role in ACP inactivation efficacy.

Using Drawings To Understand Perceptions Of Civic Engagement Across Disciplines: ‘Seeing Is Understanding’, Sharon Feeney, John Hogan

Articles

In this article, we wish to investigate if disciplinary differences exist among students when considering the topic of civic engagement. We use freehand drawing to create a learning environment in the classroom wherein students can seek to develop meaningful associations with civic engagement. The drawings examined here, produced by three different class groups, provide insights into how young adults perceive their society and their place in it, and thus communicate their understanding of civic engagement. Freehand drawing, in bypassing cognitive verbal processing routes, leads students to produce clearer and more holistic images. It allows them to put into visuals a …

Targeting Lipoprotein Biogenesis: Considerations Towards Antimicrobials, Toufic El Arnaout, Tewfic Soulimane

Articles

Decades have passed without approval of a new antibiotic class. Several companies have recently halted related discovery efforts because of multiple obstacles. One promising route under research is to target the lipoprotein maturation pathway in light of major recent findings and the virulence roles of lipoproteins. To support the future design of selective drugs, considerations and priority-setting are established for the main lipoprotein processing enzymes (Lgt, LspA, and Lnt) based on microbiology, biochemistry, structural biology, chemical design, and pharmacology. Although not all bacterial species will be similarly impacted by drug candidates, several advantages make LspA a top target to pursue …

The New Agriculture: From Food Farms To Solar Farms, Jessica Owley, Amy Wilson Morris

Articles

Across the United States, government agencies and energy developers are looking to agricultural land for development of renewable energy. One attraction of agricultural lands is that they are already relatively ecologically impaired compared with the previous solar development sites in the California and Arizona desert that have been a major source of concern for many environmental groups-and subject to expensive mitigation requirements under the Endangered Species Act. Renewable energy development pressures are accelerating the existing loss of agricultural land, heightening concerns about food security and the economic viability of agricultural communities. California farmland is at the center of this conflict. …
