Study of Toner Penetration in Papers by Laser Induced Plasma Spectroscopy and Optical Profilometry
2023
Four major toners are used in the printing industry, cyan, magenta, yellow and black (Key) for making color images on paper. Paper brands suitable for printing have thin mineral/latex coatings, and toners are applied on top of the coating in the printing process. Chemical compositions from toner to toner, as well as from coating to coating, vary according to the needs of the end user. Interactions between the toner and the coating define the final color formation of the images in printing. Hence, it is important to study characteristics and dynamics of toners on coated papers. In this paper, we have used laser-induced plasma spectroscopy (LIBS) to provide information on elemental distributi…
Liver X Receptor ligand cytotoxicity in colon cancer cells and not in normal colon epithelial cells depends on LXRβ subcellular localization
2015
Increasing evidence indicates that Liver X Receptors (LXRs) have some anticancer properties. We recently demonstrated that LXR ligands induce colon cancer cell pyroptosis through an LXRβ-dependent pathway. In the present study, we showed that human colon cancer cell lines presented differential cytoplasmic localizations of LXRβ. This localization correlated with caspase-1 activation and cell death induction under treatment with LXR ligand. The association of LXRβ with the truncated form of RXRα (t-RXRα) was responsible for the sequestration of LXRβ in the cytoplasm in colon cancer cells. Moreover t-RXRα was not expressed in normal colon epithelial cells. These cells presented a predominantl…
La réception de la culture italienne dans La Ilustración Española y Americana
2013
This study analyzes the various references to Italy in several sections of La Ilustración Española y Americana in order to assess the contribution of the magazine in the configuration of the reception of Italian culture in Spain in the late nineteenth century, through the newspaper and through network of textual features associated therewith. Este estudio analiza las diferentes referencias a Italia en varias de las secciones de La Ilustración Española y Americana con el fin de evaluar la contribución de revista en la configuración de la recepción de la cultura italiana en España a finales del siglo xix, a través del medio periodístico y de la red de rasgos textuales con él relacionada.
3D laparoscopic surgery: a prospective clinical trial
2018
Since it's introduction, laparoscopic surgery represented a real revolution in clinical practice. The use of a new generation three-dimensional (3D) HD laparoscopic system can be considered a favorable "hybrid" made by combining two different elements: feasibility and diffusion of laparoscopy and improved quality of vision. In this study we report our clinical experience with use of three-dimensional (3D) HD vision system for laparoscopic surgery. Between 2013 and 2017 a prospective cohort study was conducted at the University Hospital of Palermo. We considered 163 patients underwent to laparoscopic three-dimensional (3D) HD surgery for various indications. This 3D-group was compared to a r…
Evaluation of Permeate Quality in Pilot Scale Membrane Distillation Systems
2019
In this work, the salinity of permeate obtained with membrane distillation (MD) in pilot scale systems was analyzed. Experiments were performed with three different spiral-wound commercial modules, one from Solar Spring with 10 m2 surface membrane area and two from Aquastill with 7.2 and 24 m2. Intermittent operation meant that high permeate conductivity was measured in the beginning of each experiment, which was gradually decreasing until reaching a constant value (3&ndash
Utilizing games in the co-production of mental health services
2020
This study analyses the application of a co-production approach in utilizing digital games and game-related methods in mental health services. The goal is to offer a real-world experiment on co-production, focusing on mental health service users, active gamers and mental health practitioners who worked together in equal ways and valued each other’s unique contributions during the experiment. The implications of a co-production approach for applying digital games in the field of mental healthcare are somewhat limited and under-explored. In this case study, seven workshop sessions were held involving service users, gamers and professionals. Participants were interviewed concerning their exper…
Valodas elementu lietojuma variācijas Anglijas un Skotijas dienas laikrakstu tekstos
2019
Laikraksti ir pastāvējuši jau gadsimtiem ilgi un vēsturiski tie ir attīstījuši dažādus veidus, kas attiecināmi uz laikrakstu izmēru, mērķauditoriju, aprakstītajiem notikumiem; tomēr visiem laikrakstiem ir noteikti struktūras un satura pamatprincipi, pēc kuriem tie vadās, lai saglabātu rakstīta teksta tipiskās pazīmes visā pasaulē. Šī darba mērķis ir izpētīt valodas lietojuma variācijas dienas laikrakstu tekstos, kas parādītu, kā atšķiras tematiski atbilstošās nodaļas un valodas reģistra variācijas dažādu tipu laikrakstos dažādos publicēšanas apgabalos. Metodes: Trīs britu un skotu laikraksti ar plašāko lasītāju publiku tika izvēlēti, lai tajos noteiktu leksisko blīvumu un dažādību divās tem…
The British Press Responds to the Liberation of the Concentration Camps
2011
Following the liberation of Western concentration camps, especially Buchenwald (11 April) and Bergen-Belsen (15 April), newspapers in Europe reported a story of cruelty that seemed to surpass every other atrocity story they had told before. This chapter will examine how the liberation news was published in the mainstream British papers. It is now well known that the liberation of the camps hardly helped the British public to comprehend the true nature of the Nazi genocide.1 However, what concerns us here is to go beyond the argument according to which the dominant liberal discourse in Britain was principally responsible for influencing British understanding of the Holocaust. Instead, this c…
Severe metabolic alterations in liver cancer lead to ERK pathway activation and drug resistance
2020
Background: The extracellular signal-regulated kinase (ERK) pathway regulates cell growth, and is hyper-activated and associated with drug resistance in hepatocellular carcinoma (HCC). Metabolic pathways are profoundly dysregulated in HCC. Whether an altered metabolic state is linked to activated ERK pathway and drug response in HCC is unaddressed. Methods: We deprived HCC cells of glutamine to induce metabolic alterations and performed various assays, including metabolomics (with 13C-glucose isotope tracing), microarray analysis, and cell proliferation assays. Glutamine-deprived cells were also treated with kinase inhibitors (e.g. Sorafenib, Erlotinib, U0126 amongst other MEK inhibitors). …
Double intercultural dialogue in the Hispanic press in the United States: the case of New York newspapers
2015
Taking as a starting point research carried out in 2000 into the concept of Hispanic identity in Spanish-language newspapers in the city of New York, this article provides a diachronic analysis of these media over the period 2000–2012. In the first study, it was established that Spanish-language newspapers reflected an intercultural dialogue among different Latino groups, thus creating a pan-Hispanic identity. In this article we wish to go a step further and explore whether the Spanish-language newspapers may also reflect, and foster, a second level of intercultural dialogue between the Hispanic and the non-Hispanic communities. In order to carry out this research, a qualitative content ana…
