4812 - A0028 Gangliosides in the retina: a comparative inventory with brain and other ocular structures
2016
Purpose: Gangliosides (GG) make an extremely diverse family of glycosphingolipids particularly abundant in the brain and neural tissues. While it is known that alterations in GG metabolism are associated with visual defects, the precise biological roles of these compounds in the retina are still largely unknown. In this context, we performed an exhaustive inventory and thorough characterization of the human eye GG aiming to reveal specificities and common features of the retina compared to other ocular tissues and brain.Methods: Retina, RPE/Choroid, ciliary body, optic nerve and brain samples were collected from deceased human donors (N=7). GG were extracted and analysed by a comprehensive …
A meta-analysis of the effect size of rheumatoid arthritis on left ventricular mass: comment on the article by Rudominer et al
2009
We appreciate the work of Rudominer et al, who recently published a report describing the association of rheumatoid arthritis (RA) with increased left ventricular mass.
Are Brands Postmodern Relics? Taking a Closer Look at New Sacred Objects
2011
Summary : Ever since the Church lost its monopoly on the sacred, no longer able to solely determine its form or contents, the social sphere has gradually taken over this value, applying it to new human and social objects. As a result, the modes of expression of the sacred have multiplied, along with the subjective and intimate experiences of modern individualism. Among the vast number of potential manifestations of this value, to which almost everything now seems to aspire, this paper will concentrate on commercial brands as vectors of meaning, with the hypothesis that some of them seek to position themselves, in postmodern society, as new figures of the sacred. This area of study is close …
Carbon stocks in a 50‑year‑oldEucalyptus camaldulensisstand in Sicily, Italy
2015
Eucalyptus stands in semi-arid areas may contribute to enhance carbon (C) stocks in both biomass and soil. However, the limited information available is mainly focused on short-rotation plantations. In this study, the above- and below-ground C pools in five 50-year-old Eucalyptus camaldulensis Dehnh. stands planted on Miocenic evaporitic deposits in Sicily, Italy, with a xeric and thermic pedoclimate, were measured. Above-ground biomass was determined by partitioning and weighing branches, stem and leaves. Below-ground C pools included the determination of litter, root biomass, and soil organic and inorganic C. In terms of the above-ground biomass, the E. camaldulensis stand accumulated on …
Cardiorespiratory Fitness and the Risk of Serious Ventricular Arrhythmias: A Prospective Cohort Study.
2019
Cardiorespiratory fitness (CRF) is an established risk factor for cardiovascular disease outcomes. However, the relationship of CRF with risk of ventricular arrhythmias (VAs) is unknown. We aimed to assess the prospective association of CRF with the risk of serious VAs. Cardiorespiratory fitness, as measured by maximal oxygen uptake, was assessed using a respiratory gas exchange analyzer in 2299 middle-aged men in the Kuopio Ischemic Heart Disease prospective cohort. We corrected for within-person variability in CRF levels using data from repeated measurements 11 years apart. During median follow-up of 25.3 years (interquartile range, 18.7-27.2 years), 73 serious VAs were recorded. The age-…

Tutkin pro gradu-tutkielmassani lyhenteiden käyttöä ja muodostumista massamedian teksteissä. Tarkoituksenani on selvittää, miten lyhenteitä käytetään sekä miten ne muodostuvat uutisteksteissä ja keskustelufoorumeilla. Tutkielmassani keskityn tarkastelemaan nimenomaan lyhenteiden muodostumisen eroja median eri ympäristöissä. Selvitän, onko lyhenteiden käytössä eroja uutisteksteissä ja keskustelufoorumeilla, ja jos on, niin millaisia. Olen asettanut työlleni seuraavanlaiset tutkimuskysymykset: 1) Miten lyhenteet muodostuvat, sekä miten niitä käytetään uutisteksteissä ja keskustelufoorumeilla? Millaisia eroja lyhenteiden käytössä on? 2) Millaisia ovat lyhenteiden käytön ja muodostumisen eritys…
LA IMPORTANCIA DEL DINERO EN LA ELECCIÓN LABORAL
2014
Resumen: El objetivo fundamental del presente articulo es identificar los factores motivadores del trabajo entre los futuros directivos y trabajadores y reflexionar desde un punto de vista tanto academico como profesional sobre la importancia del dinero como factor motivador. Para ello, hemos tomado a estudiantes universitarios, en su faceta de futuros trabajadores; se concluye que el dinero por si solo no motiva y que es necesario encontrar aquel grupo de factores que motivan a los trabajadores con el objetivo de conseguir el maximo rendimiento. Los resultados nos permiten concluir que no debemos motivar tan solo con el dinero o admitiendolo como principal elemento motivacional. Palabras c…
