Articles

Lateral flow immunochromatographic assays are a powerful diagnostic tool for point-of-care tests, based on their simplicity, specificity, and sensitivity. In this study, a rapid and sensitive gold nanoparticle (AuNP) immunochromatographic strip is produced for detecting aflatoxin B1 (AFB1) in suspicious fungi-contaminated food samples. The 10 nm AuNPs were encompassed by bovine serum albumin (BSA) and AFB1 antibody. Thin-layer chromatography, gel electrophoresis and nuclear magnetic resonance spectroscopy were employed for analysing the chemical complexes. Various concentrations of AFB1 antigen (0–16 ng/mL) were tested with AFB1 antibody–BSA–AuNPs (conjugated AuNPs) and then analysed by scanning electron microscopy, ultraviolet–visible spectroscopy, and Zetasizer. The results …

Paracrine and endocrine roles have increasingly been ascribed to extracellular vesicles (EVs) generated by multicellular organisms. Central to the biogenesis, content, and function of EVs are their delimiting lipid bilayer membranes. To evaluate research progress on membranes and EVs, the International Society for Extracellular Vesicles (ISEV) conducted a workshop in March 2018 in Baltimore, Maryland, USA, bringing together key opinion leaders and hands-on researchers who were selected on the basis of submitted applications. The workshop was accompanied by two scientific surveys and covered four broad topics: EV biogenesis and release; EV uptake and fusion; technologies and strategies used to study …

Articles

Background: Oesophagectomy remains the only curative intervention for oesophageal cancer, with defined nutritional and health-related quality of life (HR-QOL) consequences. It follows therefore that there is a significant risk of decline in physical wellbeing with oesophagectomy however this has been inadequately quantified. This study prospectively examines change in physical functioning and habitual physical activity participation, from presurgery through 6-months post-oesophagectomy. Methods: Patients scheduled for oesophagectomy with curative intent were recruited. Key domains of physical functioning including exercise tolerance (six-minute walk test (6MWT)) and muscle strength (hand-grip strength), and habitual physical activity participation, including sedentary behaviour (accelerometry) were measured presurgery (T0) …

Nanostructured Materials For Food Applications: Spectroscopy, Microscopy And Physical Properties, Shubham Sharma, Swana Jaiswal, Brendan Duffy, Amit Jaiswal

Articles

Nanotechnology deals with the matter of atomic or molecular scale. Other factors that define the character of a nanoparticle are its physical and chemical properties, such as surface area, surface charge, hydrophobicity of the surface, the thermal stability of the nanoparticle, and its antimicrobial activity. A nanoparticle is usually characterized by using microscopic and spectroscopic techniques. Microscopic techniques are used to characterize the size, shape, and location of the nanoparticle by producing an image of the individual nanoparticle. Several techniques, such as scanning electron microscopy (SEM), transmission electron microscopy/high resolution transmission electron microscopy (TEM/HRTEM), atomic force microscopy (AFM) and scanning …

Metamorphosis: A Minority Professor's Life, Richard Delgado

Articles

This article is a dark semiautobiographical takeoff on a famous novel by Franz Kafka I use the predicament of Gregor the central character in The Metamorphosis as a thematic metaphor to explain a series of events in the life of an outwardly successful man of color teaching law It proceeds in a series of 37 short vignettes told in the course of a bedside conversation in which my young firebrand Rodrigo turns tables on his usual foil and straight man "the Professor" and asks him a few questions about his life and career Until now the two had focused on …

Race, Racism, And American Law': A Seminar From The Indigenous, Black, And Immigrant Legal Perspectives, Monte Mills, Eduardo R.C. Capulong, Andrew King-Ries

Articles

Flagrant racism has characterized the Trump era from the onset. Beginning with the 2016 presidential campaign, Trump has inflamed long-festering racial wounds and unleashed white supremacist reaction to the nation’s first black President, in the process destabilizing our sense of the nation’s racial progress and upending core principles of legality, equality, and justice. As law professors, we sought to rise to these challenges and prepare the next generation of lawyers to succeed in a different and more polarized future. Our shared commitment resulted in a new course, “Race, Racism, and American Law,” in which we sought to explore the roots …

Attacking Innovation, Xuan-Thao Nguyen, Jeffrey A. Maine

Articles

Economists generally agree that innovation is important to economic growth and that government support for innovation is necessary. Historically, the U.S. government has supported innovation in a variety of ways: (1) a strong legal system for patents; (2) direct support through research performed by government agencies, grants, loans, and loan guarantees; and (3) indirect support through various tax incentives for private firms. In recent years, however, we have seen a weakening of the U.S. patent system, a decline in direct funding of research, and a weakening of tax policy tools used to encourage new innovation. These disruptive changes threaten the …

The Surprising Reach Of Fda Regulation Of Cannabis Even After Rescheduling, Sean M. O'Connor, Erika Lietzan

Articles

As more states legalize cannabis, the push to “deschedule” it from the Controlled Substances Act is gaining momentum. At the same time, the Food and Drug Administration (FDA) recently approved the first conventional drug containing a cannabinoid derived from cannabis—cannabidiol (CBD) for two rare seizure disorders. This would all seem to bode well for proponents of full federal legalization of medical cannabis. But some traditional providers are wary of drug companies pulling medical cannabis into the regular small molecule drug development system. The FDA’s focus on precise analytical characterization and on individual active and inactive ingredients may be fundamentally inconsistent …

Graphene Nanoflake Uptake Mediated By Scavenger Receptors, Fatima Alnasser, Valentina Castagnola, Luca Boselli, Margarita Esquivel-Gaon, Esen Efeoglu, Jennifer Mcintyre, Hugh Byrne, Kenneth A. Dawson

Articles

The biological interactions of graphene have been extensively investigated over the last 10 years. However, very little is known about graphene interactions with the cell surface and how the graphene internalization process is driven and mediated by specific recognition sites at the interface with the cell. In this work, we propose a methodology to investigate direct molecular correlations between the biomolecular corona of graphene and specific cell receptors, showing that key protein recognition motifs, presented on the nanomaterial surface, can engage selectively with specific cell receptors. We consider the case of apolipoprotein A-I, found to be very abundant in the …

Vibrational Characterization Of Granulosa Cells From Patients Affected By Unilaterial Ovarian Endometriosis: New Insights From Infrared And Raman Microspectroscopy, Valentina Notarstefano, Giorgia Gioacchini, Hugh Byrne, Carlotta Zaca, Eleni Sereni, Lisa Vaccari, Andrea Borini, Oliana Carnevali

Articles

Endometriosis is a chronic gynaecological disease characterised by the presence of endometrial cells in extra-uterine regions. One of the main factors impacting on the fertility of women affected by endometriosis is the poor oocyte quality. Granulosa Cells (GCs) regulate oocyte development and maintain the appropriate microenvironment for the acquisition of its competence; hence, the dysregulation of these functions in GCs can lead to severe cellular damages also in oocytes. In this study, luteinized GCs samples were separately collected from both ovaries of women affected by Unilateral Ovarian Endometriosis and analysed by infrared and Raman microspectroscopy. The spectral data were compared …

Analysis Of Bodily Fluids Using Vibrational Spectroscopy: A Direct Comparison Of Raman Scattering And Infrared Absorption Techniques For The Case Of Glucose In Blood Serum, Drishya Prachalil, Clément Bruno, Franck Bonnier, Helen Blasco, Igor Chourpa, Matthew Baker, Jennifer Mcintyre, Hugh Byrne

Articles

Analysis of biomarkers present in the blood stream can potentially deliver crucial information on patient health and indicate the presence of numerous pathologies. The potential of vibrational spectroscopic analysis of human serum for diagnostic purposes has been widely investigated and, in recent times, infrared absorption spectroscopy, coupled with ultra-filtration and multivariate analysis techniques, has attracted increasing attention, both clinical and commercial. However, such methods commonly employ a drying step, which may hinder the clinical work flow and thus hamper their clinical deployment. As an alternative, this study explores the use of Raman spectroscopy, similarly coupled with ultra-filtration and multivariate analysis …

Raman Spectroscopy As A Potential Tool For Label Free Therapeutic Drug Monitoring In Human Serum: The Case Of Busulfan And Methotrexate, Drishya Parachalil, Franck Bonnier, Deirdre Commerford, Igor Chourpa, Jennifer Mcintyre, Hugh Byrne

Articles

A methodology is proposed, based on Raman spectroscopy coupled with multivariate analysis, to determine the Limit of Detection (LOD) and Limit of Quantification (LOQ) for therapeutic drug monitoring in human serum, using the examples of Busulfan, a cell cycle non-specific alkylating antineoplastic agent, and, Methotrexate, a chemotherapeutic agent and immune system suppressant. In this study, ultrafiltration is employed to fractionate spiked human pooled serum to efficiently recover the drug in the filtrate prior to performing Raman analysis. The drug concentration ranges were chosen to encompass the recommended therapeutic ranges and toxic levels in patients. Raman spectra were collected from the …

Improved Performance Of Near Infrared Excitation Raman Spectroscopy Using Reflective Thin-Film Gold On Glass Substrates For Cytology Samples, Sinead Barton, Kevin O'Dwyer, Marion Butler, Hugh Byrne, Luke O'Neill, Bryan M. Hennelly

Articles

Confocal near-infrared Raman spectroscopy has been shown to have applications in the area of clinical biology. A source wavelength in the near infrared is preferred over visible wavelengths for inspecting biological samples due to superior wave number resolution and reduced photo damage. However, these excitation sources have a number of drawbacks when compared to lasers in the visible wavelength region, including the requirement to use expensive highly pure crystal substrates such as Raman grade calcium fluoride as well as long acquisition times due to the lower Raman scattering efficiency. This paper investigates the use of a reflective substrate comprising a …

Numerically Modelling Time And Dose Dependent Cytotoxicity, Hugh Byrne, Marcus A. Maher

Articles

Dose-response curves are fundamental tools of in vitro toxicology, extensively employed in toxicant or drug screening. They are expressed by a variety of end-points and assays, measured at different time-points in a choice of cell-lines, but are typically quantified only using the mean concentration for 50% response (e.g. drug efficacy or pathway inhibition) as an indicator of overall effect. However, the response is the result of a complex and dynamic cascade of events which occur between the initial exposure and the measured end-point, and the characteristic rates of the contributing stages govern the dose response and ultimately the measured characteristic …

Effect Of Cold Plasma On The Techno-Functional Properties Of Animal Protein Food Ingredients, Juan M. Pérez-Andrés, Carlos Álvarez, Patrick J. Cullen, Brijesh K. Tiwari

Articles

Proteins, as food ingredients, are employed in the food industry, not only for their high nutritional value, but also because of their techno-functional properties. Modifications of their native structure due to the action of external factors such as pH, temperature or processing by emerging technologies, can lead to changes in their functionality; and consequently, their applicability. The present study investigates the effects of cold atmospheric air plasma on the techno-functional properties of two common food ingredients (haemoglobin and gelatine from pork), and a novel source of functional proteins extracted from a meat co-product (bovine lung protein). Significant effects were found …

Towards An Ontology For Soft Robots: What Is Soft?, Kevin Chubb, Damon Berry, Ted Burke

Articles

The advent of soft robotics represents a profound change in the forms robots will take in the future. However, this revolutionary change has already yielded such a diverse collection of robots that attempts at defining this group do not reflect many existing ‘soft’ robots. This paper aims to address this issue by scrutinising a number of descriptions of soft robots arising from a literature review with the intention of determining a coherent meaning for soft. We also present a classification of existing soft robots to initiate the development of a soft robotic ontology. Finally, discrepancies in prescribed ranges of Young’s …

Visceral Adipose Tissue Modulates Radiosensitivity In Oesophageal Adenocarcinoma, Ann Marie Mongan, Niamh Lynam-Lennon, Suzanne Doyle, Rory Casey, Eibhlin Carr, Aoife Cannon, Melissa J Conroy, Graham P Pidgeon, Lorraine Brennan, Joanne Lysaght, John V. Reynolds, Jacintha O’Sullivan

Articles

Oesophageal adenocarcinoma (OAC) is an exemplar model of obesity-associated cancer. Response to neoadjuvant chemoradiotherapy (NA CRT) is a clinical challenge. We examined if visceral adipose tissue and obesity status alter radiosensitivity in OAC. The radioresistant (OE33R) and radioresponsive (OE33P) OAC isogenic model was cultured with adipose tissue conditioned media from three patient cohorts: non-cancer patients, surgery only OAC patients and NA CRT OAC patients. Cell survival was characterised by clonogenic assay, metabolomic profiling by nuclear magnetic resonance spectroscopy and adipokine receptor gene expression by qPCR. A retrospective in vivo study compared tumour response to NA CRT in normal weight (n=53) …

Peace And Subjectivity, Louis E. Wolcher

Articles

So long as there is law there can be no universal human right to peace. This is because legalized violence, whether in threat or in deed, constitutes the very antithesis of peaceful relations from the point of view of those whom law represses. Law cannot define peace as the absence of all violence—and still less as the absence of all legalized suffering—without gainsaying justice, for as Pascal says, “Justice without might is helpless; might without justice is tyrannical.” Although legal outcomes, like falling boulders and pouncing lions, can always be imputed to historical causes, experience teaches that legal actors generally …

Clown Eggs, Dave Fagundes, Aaron Perzanowski

Articles

Since 1946, many clowns have recorded their makeup by having it painted on eggs that are kept in a central registry in Wookey Hole, England. This tradition, which continues today, has been referred to alternately as a form of informal copyright registration and a means of protecting clowns’ property in their personae. This Article explores the Clown Egg Register and its surrounding practices from the perspective of law and social norms. In so doing, it makes several contributions. First, it contributes another chapter to the growing literature on the norms-based governance of intellectual property, showing how clowns—like comedians, roller derby …

Privacy In The Age Of Medical Big Data, W. Nicholson Price Ii, I. Glenn Cohen

Articles

Big data has become the ubiquitous watch word of medical innovation. The rapid development of machine-learning techniques and artificial intelligence in particular has promised to revolutionize medical practice from the allocation of resources to the diagnosis of complex diseases. But with big data comes big risks and challenges, among them significant questions about patient privacy. Here, we outline the legal and ethical challenges big data brings to patient privacy. We discuss, among other topics, how best to conceive of health privacy; the importance of equity, consent, and patient governance in data collection; discrimination in data uses; and how to handle …

How U.S. Family Law Might Deal With Spousal Relationships Of Three (Or More) People, Edward D. Stein

Articles

For much of this nation's history, the vast majority of people have believed that being married to more than one person at the same time is deeply problematic. Further, polygamous marriage has never been legal in the United States. Despite this, some people have been in plural or group relationships and some of these people have wished to gain legal recognition for these relationships. The arguments for recognizing such relationships are persuasive, but the prospects for legalization of polygamous marriage seem slim in the near future. This Article offers a suggestion of how the law of domestic relations might deal …

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 …

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 …

Investigation Of Mechanisms Involved In Germination Enhancement Of Wheat (Triticum Aestivum) By Cold Plasma: Effects On Seed Surface Chemistry And Characteristics, Agata Los, Dana Ziuzina, Daniela Boehm, Patrick J. Cullen, Paula Bourke

Articles

Recent reports indicate that atmospheric cold plasma (ACP) treatment of seeds can enhance their germination, however, the mechanisms of action are not yet entirely clear. In the present work, we report on the effects of plasma treatment on wheat seed germination and seedling growth. Additionally, changes in the surface chemistry and characteristics of the wheat seeds exposed to plasma were investigated. Treatments of 30–60 s significantly enhanced the germination rate and showed positive effects on seedling growth. ACP resulted in changes of seed surface and chemical characteristics including water uptake and contact angle values. Changes in seed pH and total …
