To compare macronutrient intakes of Swedish children and adolescents to population goals; to identify the major sources of energy, fat, saturated fat and sucrose; and to simulate the effect adherence to current food-based dietary guidelines (FBDG) would have on saturated fat and sucrose intakes. Cross-sectional study. From 24 h recall data, food groups contributing most to energy, fat, saturated fat and sucrose were identified. Based on the prevailing consumption of foods mentioned in the FBDG, we simulated five scenarios: changes in milk and yoghurt; cheese; energy-dense, nutrient-dilute foods; soft drinks; and burger and sausage consumption. Stockholm and Örebro (Sweden) in …

Exogenous Fms-Like Tyrosine Kinase 3 Ligand Overrides Brain Immune Privilege And Facilitates Recognition Of A Neo-Antigen Without Causing Autoimmune Neuropathology, Daniel Larocque, Nicholas S. R. Sanderson, Josée Bergeron, James Curtin, Joe Girton, Mia Wibowo, Niyati Bondale, Kurt M. Kroeger, Jieping Yang, Liliana M. Lacayo, Kevin C. Reyes, Catherine Farrokhi, Robert N. Pechnick, Maria G. Castro, Pedro R. Lowenstein

Articles

Soluble antigens diffuse out of the brain and can thus stimulate a systemic immune response, whereas particulate antigens (from infectious agents or tumor cells) remain within brain tissue, thus failing to stimulate a systemic immune response. Immune privilege describes how the immune system responds to particulate antigens localized selectively within the brain parenchyma. We believe this immune privilege is caused by the absence of antigen presenting dendritic cells from the brain. We tested the prediction that expression of fms-like tyrosine kinase ligand 3 (Flt3L) in the brain will recruit dendritic cells and induce a systemic immune response against exogenous influenza …

From Chevron To Massachusetts: Justice Stevens's Approach To Securing The Public Interest, Kathryn A. Watts

Articles

During the past three decades, one Supreme Court justice— John Paul Stevens—has authored two of the most significant administrative law decisions that speak to the judiciary’s role in checking agency interpretations of the statutes that they administer. In Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc., Justice Stevens’s landmark 1984 decision unanimously upheld the EPA’s construction of a term found in the Clean Air Act. Subsequently, in Massachusetts v. EPA, Justice Stevens’s 2007 opinion for a five-justice majority handed a major win to global environmental security by ordering the EPA to reconsider its refusal to regulate greenhouse …

Peeping Hals: Making Sense Of Artificial Intelligence And Privacy, Ryan Calo

Articles

The field of artificial intelligence, broadly defined as the study and practice of designing intelligent agents, is at least six decades into its existence as a formal discipline. Sometimes called “computational” or “synthetic” intelligence, AI borrows from and informs a wide variety of subjects, including philosophy, psychology, linguistics, neuroscience, statistics, economics, and law. Techniques of AI underpin all manner of industrial and consumer applications - from the complex neural nets used in data mining, down to the ‘fuzzy logic’ used by commercial washers and driers.

Insofar as “the issues of AI are directly related to [the] self-image of human beings”, …

The Consequence Of Human Differences, Jospeh Vining

Articles

This essay explores the ways in which the recognition of individual and person in the legal form of thought distinguishes it from forms of thought in evolutionary biology and mathematics that are put forward as means to a complete picture of the world. The essay observes that the legal form of thought is in fact deeply involved in our modern understanding of Nature itself.

If I Had A Hammer: Can Shepardizing, Synthesis, And Other Tools Of Legal Writing Help Build Hope For Law Students?, Edward R. Becker

Articles

Are lawyers mechanics? In 1920, photographer Lewis Hines took a striking photo of a powerhouse mechanic sure-handedly wielding a large wrench to tighten bolts on a steam pump. This picture may bring to mind many things, but I suspect that many legal writing professors in our (past or present) incarnations as practicing attorneys would not look at this image and think, "My job is a lot like that." Similarly, I assume that many of our students do not think of a lawyer's role in this way. Indeed, many of our students might have chosen to pursue a career in law …

Mulieris Dignitatem And The Exclusivity Of Marriage Under Law, Howard Bromberg

Articles

Jesus Christ established monogamy, the marriage of one man to one woman, as the canonical norm of his church and the juridical norm for all nations. This was a unique event in the history of the cultures and religions of the world. The Catholic Church has always defended its canonical norm of monogamy, often with great opposition. Through its influence, monogamy has been established as law in the Western world and in almost all cultures influenced by Western law and norms. The emerging jurisprudence of the United States, however, rejects any religious derivation as the basis of our laws. With …

Family Values In The Jewish Tradition, J. David Bleich

Articles

In Family Values in the Jewish Tradition, Professor J. David Bleich presents Judaism as a religion of law. He describes the family unit, "both as a social unit and as a legal institution," and how it helps to provide comfort, companionship, and stability. He discusses the role of reproduction within the family unit, artificial insemination, and the homosexual act (not the homosexual as a person). Professor Bleich concludes with a discussion of the phrase, "be fruitful and multiply." He notes that this phrase is understood as both a commandment and a blessing.

The Basic Law At 60 - Equality And Difference: A Proposal For The Guest List To The Birthday Party, Susanne Baer

Articles

The German constitution, named "Basic Law", has proven to work although many did not believe in it when it was framed. Others emphasize desiderata. Sabine Berghahn commented at the 50th birthday that it has developed "far too slowly and [some] has even gone completely wrong." ' Jutta Limbach, former President of the Federal Constitutional Court, observed that constitutional history was "anything but regal, but very difficult and full of obstacles. '' 2 Former Chancellor Willy Brandt famously called the constitution "a snail on thin ice." So what is missing when we analyze the Basic Law, and what should be finally …

Study Of The Microbial Diversity And Antimicrobial Properties Of Irish Edible Brown Seaweeds, Shilpi Gupta, Gaurav Rajauria, Nissreen Abu-Ghannam

Articles

Brown Irish edible seaweeds, Himanthalia elongata, Laminaria sachharina and Laminaria digitata, were evaluated for the microbiota in raw and heat processed form. Raw seaweeds showed complete absence of aerobic mesophiles, halophiles, yeasts and molds. However, heating at 85 C for 15 min resulted in spore germination. Bacterial counts as high as 107 were observed for aerobic mesophiles and halophiles. Heating above 95 C for 15 min resulted in complete inactivation of surface microflora. Bacteria belonging to Bacillaceae, Paenibacillaceae, Moraxellaceae and Enterobacteriaceae family were identified by 16S rRNA sequencing. In vitro antimicrobial activity of the methanolic extracts of the seaweed on …

Use Of Fourier Transform Infrared Spectroscopy And Chemometric Data Analysis To Evaluate Damage And Age In Mushrooms (Agaricus Bisporus) Grown In Ireland, Aoife O'Gorman, Gerard Downey, Aoife Gowen, Catherine Barry-Ryan, Jesus Maria Frias

Articles

The aim of this research was to investigate whether the chemical changes induced by mechanical damage and aging of mushrooms can be (a) detected in the mid-infrared absorption region and (b) identified using chemometric data analysis. Mushrooms grown under controlled conditions were bruise-damaged by vibration to simulate damage during normal transportation. Damaged and non-damaged mushrooms were stored for up to 7 days post-harvest. Principal component analysis of FTIR spectra showed evidence that physical damage had an effect on tissue structure and the aging process. Random forest classification models were used to predict damage in mushrooms producing models with error rates …

Influence Of Cultivation Conditions On The Production Of A Thermostable Extracellular Lipase From Amycolatopsis Mediterranei Dsm 43304, Dharmdendra Dheeman, Jesus Maria Frias, Gary Henehan

Articles

Among several lipase producing actinomycete strains screened, Amycolatopsis mediterranei DSM 43304 was found to produce a thermostable, extracellular lipase. Culture condition and nutrient source modification studies involving carbon sources, nitrogen sources, incubation temperature and medium pH were carried out. Lipase activity of 1.37 ± 0.103 IU/ml of culture medium was obtained in 96 h at 28 °C and pH 7.5 using linseed oil and fructose as carbon sources and a combination of phytone peptone and yeast extract (5:1) as nitrogen sources. In optimal culture conditions the lipase activity was enhanced 12-fold with a 2-fold increase in lipase specific activity. The …

Visible Near-Infrared Hyperspectral Imaging For The Identification And Discrimination Of Brown Blotch Disease On Mushroom (Agaricus Bisporus) Caps, Edurne Gaston, Jesus Maria Frias, Patrick J. Cullen, Colm O’Donnell, Aoife Gowen

Articles

Brown blotch, caused by pathogenic Pseudomonas tolaasii (P. tolaasii), is the most problematic bacterial disease in Agaricus bisporus mushrooms. Although it does not cause any health problems, it reduces the consumer appeal of mushrooms in the market place, generating important economical losses worldwide. Hyperspectral imaging (HSI) is a non-destructive technique that combines imaging and spectroscopy to obtain information from a sample. The objective of this study was to investigate the use of HSI for brown blotch identification and discrimination from mechanical damage on mushrooms. Hyperspectral images of mushrooms subjected to i) no treatment, ii) mechanical damage or iii) …

Postharvest Hardness And Color Evolution Of White Button Mushrooms (Agaricus Bisporus)., Debabandya Mohapatra, Zuberi M. Bira, Joseph Kerry, Jesus Maria Frias, Fernanda A.R. Oliveira

Articles

The quality evaluation of mushrooms was studied by storing fresh white button mushroom (Agaricus bisporus) for 6-8 days, at various controlled temperature conditions (3.5 -15°C) and measuring the instrumental textural hardness and color of the mushroom cap for different product batches. A non linear mixed effect weibull model was used to describe mushroom cap texture and color kinetics during storage considering the batch variability into account. Storage temperature was found to play a significant role in controlling texture and colour degradation. On lowering storage temperature i) the extent of the final browning extent in the mushroom after storage …

Substrate Profiling And Aldehyde Dismutase Activity Of The Kvβ2 Subunit Of The Mammalian Kv1 Potassium Channel, A. Kumari, Barry Ryan, J. Dolly, Gary Henehan

Articles

Voltage-dependent potassium channels (Kv) are involved in various cellular signalling processes by governing the membrane potential of excitable cells. The cytosolic face of these α subunit-containing channels is associated with β subunits that can modulate channel responses. Surprisingly, the β subunit of the mammalian Kv1 channels, Kvβ2, has a high level of sequence homology with the aldo-keto reductase (AKR) superfamily of proteins. Recent studies have shown that Kvβ2 can catalyze the reduction of aldehydes and, most significantly, that channel function is modulated when Kvβ2-bound NADPH is concomitantly oxidized. As a result, the redox chemistry of this subunit is crucial to …

Quality And Safety Assessment During The Ozonation Of Cloudy Apple Juice, Sonal Patil, B. Torres, Brijesh Tiwari, Hilda Wingaard, Paula Bourke, Patrick J. Cullen, C. O'Donnell, Vasilis Valdramidis

Articles

Traditionally, ozone processing within the food industry has focused on solid foods by either gaseous treatment or washing with ozonated water. However, with the FDA’s approval of ozone as a direct additive to food, the potential for liquid applications has emerged. This study investigates the effect of ozone processing on microbial inactivation (E. coli ATCC 25922 and NCTC 12900), and quality parameters (colour, phenolic content) of apple juice. Apple juice samples were ozonated at room temperature (20±1.5^oC) with an ozone concentration of 0.048 mg O₃ min^-1 ml^-1 and treatment time of 0 to 10 …

Untreated And Enzyme-Modified Bovine Whey Products Reduce Association Of Salmonella Typhimurium, Escherichia Coli O157:H7 And Cronobacter Malonaticus (Formerly Enterobacter Sakazakii) To Caco-2 Cells, Rachel Halpin, D.B. Brady, E.D. O’Riordan, M. O’Sullivan

Articles

Adhesion of a micro-organism to a cell surface is often considered to be the first step in pathogenesis. Inhibiting this process may have therapeutic effects in vivo. This study investigates the inhibitory effects of various bovine whey products on the association of Salm. Typhimurium, E. coli O157:H7 and C. malonaticus (formerly Enterobacter sakazakii) to the human CaCo-2 cell line. Invasion of CaCo-2 cells by Salm. Typhimurium and C. malonaticus was also examined.

Assessment Of The Accuracy Of An Ultrasound Elastography Liver Scanning System Using A Pva-Cryogel Phantom With Optimal Acoustic And Mechanical Properties, S. Cournane, Louise Cannon, Jacinta Browne, Andrew Fagan

Articles

The accuracy of a transient elastography liver-scanning ultrasound system was assessed using a novel application of PVA-cryogel as a tissue-mimicking material with acoustic and shear elasticity properties optimized to best represent those of liver tissue. Although the liver scanning system has been shown to offer a safer alternative for diagnosing liver cirrhosis through stiffness measurement, as compared to the liver needle biopsy exam, the scanner’s accuracy has not been fully established. The Young’s elastic modulus values of 5-6wt% PVA cryogel phantoms, also containing glycerol and 0.3μm Al2O3 and 3μm Al2O3, were measured using a ‘gold standard’ mechanical testing technique and …

Studies Of Chemical Fixation Effects In Human Cell Lines Using Raman Microspectroscopy, Aidan Meade, Colin Clarke, Florence Draux, Ganesh Sockalingum, Michel Manfait, Fiona Lyng, Hugh Byrne

Articles

The in vitro study of cellular species using Raman spectroscopy has proven a powerful non-invasive modality for the analysis of cell constituents and processes. This work uses micro-Raman spectroscopy to study the chemical fixation mechanism in three human cell lines (normal skin, normal bronchial epithelium, and lung adenocarcinoma) employing fixatives that preferentially preserve proteins (formalin), and nucleic acids (Carnoy’s fixative and methanol–acetic acid). Spectral differences between the mean live cell spectra and fixed cell spectra together with principal components analysis (PCA), and clustering techniques were used to analyse and interpret the spectral changes. The results indicate that fixation in formalin …

Functional And Pathological Analysis Of Biological Systems Using Vibrational Spectroscopy With Chemometric And Heuristic Approaches, Aidan Meade, Colin Clarke, Franck Bonnier, Kelvin W. Poon, Amaya Garcia, Peter Knief, Kamila Ostrowska, Lorenzo Salford, Haq Nawaz, Fiona Lyng, Hugh Byrne

Articles

Vibrational spectroscopy (Raman and FTIR microspectroscopy) is an attractive modality for the analysis of biological samples since it provides a complete non-invasive acquisition of the biochemical fingerprint of the sample. Studies in our laboratory have applied vibrational spectroscopy to the analysis of biological function in response to external agents (chemotherapeutic drugs, ionising radiation, nanoparticles), together with studies of the pathology of tissue (skin and cervix) in health and disease. Genetic algorithms have been used to optimize spectral treatments in tandem with the analysis of the data (using generalized regression neural networks (GRNN), artificial neural networks (ANN), partial least squares modelling …

Growth kinetics of lactic acid bacteria (LAB; Lactobacillus plantarum) was studied using three species of edible Irish brown seaweeds Himanthalia elongata, Laminaria digitata and Laminaria saccharina. As part of the screening process, growth of the LAB was carried out on raw and heat treated forms of seaweeds. The seaweed species in their raw state could not support the growth of L. plantarum. Heat treatment resulted in almost 4 times increase in …

Figurational Dynamics And Parliamentary Discourses Of Living Standards In Ireland, Paddy Dolan

Articles

While the concept of living standards remains central to political debate, it has become marginal in sociological research compared to the burgeoning attention given to the topic of consumer culture in recent decades. However, they both concern how one does and should consume, and, indeed, behave at particular times. I use the theories of Norbert Elias to explain the unplanned but structured (ordered) changes in expected standards of living over time. This figurational approach is compared to other alternative explanations, particularly those advanced by Bourdieu, Veblen and Baudrillard. Though these offer some parallels with Elias’s theories, I argue that consumption …
