negative pathogen Pseudomonas aeruginosa, and this enzyme orchestrates several physiopathological events during bacteria-host interplays. LasB is considered to be a potential target for the development of an innovative chemotherapeutic approach, especially against multidrug-resistant strains. Recently, our group showed that 1,10-phenanthroline-5,6-dione (phendione), [Ag(phendione)2]ClO4 (Ag-phendione) and [Cu(phendione)3](ClO4)2.4H2O (Cu-phendione) had anti-P. aeruginosa action against both planktonic- and biofilm-growing cells. In the present work, we have evaluated the effects of these compounds on the (i) interaction with the lasB active site using in silico approaches, (ii) lasB proteolytic activity by using a specific fluorogenic peptide substrate, (iii) lasB gene expression by real time-polymerase chain …

Discrimination Of Breast Cancer From Benign Tumours Using Raman Spectroscopy, Fiona Lyng, Damien Traynor, Thi Nguyet Que Nguyen, Aidan Meade, Fazle Rakib, Rafif Al-Saady, Erik Goormaghtigh, Khalid Al-Saad, Mohamed H. Ali

Articles

Breast cancer is the most common cancer among women worldwide, with an estimated 1.7 million cases and 522,000 deaths in 2012. Breast cancer is diagnosed by histopathological examination of breast biopsy material but this is subjective and relies on morphological changes in the tissue. Raman spectroscopy uses incident radiation to induce vibrations in the molecules of a sample and the scattered radiation can be used to characterise the sample. This technique is rapid and non-destructive and is sensitive to subtle biochemical changes occurring at the molecular level. This allows spectral variations corresponding to disease onset to be detected. The aim …

Seasonal Variability Of Sediment Controls Of Carbon Cycling In An Agricultural Stream, Sophie Comer-Warner, Daren Gooddy, Sami Ullah, Luke Glover, Aishling Percival, Nicholas Kettridge, Stefan` Krause

Articles

Streams and rivers are‘active pipelines’where high rates of carbon (C) turnover can lead to globally importantemissions of carbon dioxide (CO2) and methane (CH4) from surface waters to the atmosphere. Streambed sedi-ments are particularly important in affecting stream chemistry, with rates of biogeochemical activity, and CO2and CH4concentrations far exceeding those in surface waters. Despite an increase in research on CO2and CH4instreambed sediments there is a lack of knowledge and insight on seasonal dynamics. In this study the seasonallyvariable effect of sediment type (sand-dominated versus gravel-dominated) on porewater C cycling, includingCO2and CH4concentrations, was investigated. We found high concentrations of CO2and CH4in the …

Predicting Quality Attributes And Waste Of Strawberry Packed Under Modified Atmosphere Throughout The Cold Chain, Kompal Johsi, Brijesh Tiwari, Patrick J. Cullen, Jesus Maria Frias

Articles

Modified Atmosphere Packaging (MAP) is used commercially to extend the shelf life of strawberries. The attainment of desired gas (O2, CO2) concentrations inside MAP relies on the product respiration and the mass transfer through packaging and will affect the quality. The objective of this work is to build a mathematical model for strawberries to assess the effect of the uncertainties on headspace gas concentration and quality: 1) cold chain related temperature and relative humidity variations and 2) variability associated to product respiration and quality based on literature. Weight loss was more influenced by the cold chain storage conditions (temperature and …

Investigation Of Coastal Sea-Fog Formation Using The Wibs (Wide Band Integrated Bioaerosol Sensor) Technique, Shane M. Daly, David O'Connor, David A. Healy, Stig Hellebust, Jovanna Arndt, Eoinj. Mcgillicuddy, Patrick Feeney, Michael Quirke, John C. Wenger, John R. Sodeau

Articles

Abstract. A wideband integrated bioaerosol sensor (WIBS4) was deployed in Haulbowline Island, Cork Harbour, to detect fluorescence particles in real time during July and September 2011. A scanning mobility particle sizer (SMPS) was also installed providing sizing analysis of the particles over the 10–450nm range. During the campaign, multiple fog formation events occurred; they coincided with dramatic increases in the recorded fluorescent particle counts. The WIBS sizing and fluorescence intensity profiles indicated that the origin of the signals was potentially non-biological in nature (i.e. PBAPs, primary biological aerosol particles). Furthermore, the data did not support the presence of known fluorescing …

Articles

Anticancer drugs are prescribed and administrated to an increasing number of patients on a daily basis. As a consequence, a number of concerns have been raised about the patient health and safety in the case that the drugs administered are not at the required concentration or even worse not the correct ones. Quality control of therapeutic solutions has therefore been extensively implemented in hospital environments, in order to avoid any failure in the intense workflow faced by administering pharmacists. In the present study, infrared (IR) and Raman spectroscopy have been employed for the analysis of 3 commercially available therapeutic solutions …

Traversing States: A Reflection On Digital Technology And Simondon's Critique Of Hylomorphism, Michael O'Hara

Articles

In this article, I examine Simondon's concept of the technical object reflecting on its analogous relationship to digital technology. Intrinsic to such an analysis is Simondon's distinction between the abstract and concrete and his specific critique of the hylomorphic model. In a deeply rich example, Simondon, contra Aristotle, mobilises the process of mould-making as an exemplar of the modulated ensemble of forces that prefigure any formations of matter through form. I analyse Simondon's paradigmatic criticism while at the same time carving out the potential intersections that emerge through the kinaesthetic awareness of the body. By doing so I highlight the …

Children As Bargaining Chips, Clare Ryan

Articles

The parent- child relationship is one of the most valued and protected relationships in constitutional and family law. At the same time, the state has custodial power over children: a power that is necessary in some cases to protect vulnerable children from danger, neglect, and abandonment. But because the parent-child bond is so powerful, state actors can be tempted to exploit it for their own purposes. Custodial power over children provides state actors with the means to put pressure on the parent by threatening to remove the child. In these circumstances, the state uses the child as a bargaining chip …

Ripensare La Razionalità: La Crescita Di Significato E I Limiti Del Formalismo, Susan Haack

Articles

Man mano che la nostra conoscenza e la nostra esperienza crescono, i concetti assumono un significato nuovo e più ricco. La filosofia del linguaggio recente (post-Fregeana) hanno prestato poca attenzione a questo fenomeno; e filosofi radicali come Feyerabend e Rorty diedero per scontato che il cambiamento di significato fosse una minaccia alla razionalità. Ma i pensatori nella tradizione pragmatica classica – Peirce nella filosofia della scienza e, più implicitamente, Holmes nella teoria giuridica – riconobbero l’importanza della crescita di significato e capirono come questa potesse contribuire al progresso della scienza e all’adattamento di un sistema giuridico al cambiare delle circostanze. …

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 …
