ChemInform Abstract: Synthesis of 3-Triazenopyrroles.

2010

Abstract The 3-triazenopyrroles, a new class of pyrrole derivatives, were synthesized in quantitative yield by coupling 3-diazopyrroles with secondary amines.

Interpretation of epicardial mapping by means of computer simulations: Applications to calcium, lidocaine and to BRL 34915

1992

The aim of this work was to compare experimental investigations on effects of lidocaine, calcium and, BRL 34915 on reentries to simulated data obtained by use of a model of propagation based on the Huygens' construction method already described in previous works. Calcium and lidocaine effects are investigated on anisotropic conduction conditions. In both cases, reduction in conduction velocities are observed. In lidocaine case, a refractory area is located along the longitudinal axis. In agreement with experimental electrical mapping, the simulations show that the stabilization of reentrant excitation is mainly due to the existence of this refractory area around which the reentrant circuit …

The relaxant effects of cromakalim (BRL 34915) on human isolated airway smooth muscle

1992

Cromakalim (BRL 34915) is a potassium channel opener with therapeutic potential as a bronchodilator in asthma. Cromakalim (0.1–30 μmol/l) inhibited the spontaneous tone of human isolated bronchi n a concentration-related manner being nearly as effective as isoprenaline or theophylline. The order of relaxant potencies (expressed as -log10 IC50 mol/l; mean ±SEM) was isoprenaline (7.29 ± 0.27; n = 8) > cromakalim (5.89 ± 0.12; n = 7) > theophylline (4.07 ±0.13; n = 10). In human bronchi where tone had been raised by addition of histamine (0.1 mmol/l), acetylcholine (0.1 mmol/l) or leukotriene D4 (LTD4, 0.1 μmol/l), the relaxant effect of cromakalim was substantially reduced. Cromakalim suppres…

Effects of SCA40 on human isolated bronchus and human polymorphonuclear leukocytes: comparison with rolipram, SKF94120 and levcromakalim

1996

1. SCA40 (0.1 nM-0.1 mM) produced concentration-dependent suppression of the spontaneous tone of human isolated bronchus (-log EC50 = 6.85 +/- 0.09; n = 10) and reached a maximal relaxation similar to that of theophylline (3 mM). The potency (-log EC50 values) of SCA40 compared to other relaxants was rolipram (7.44 +/- 0.12; n = 9) > SCA40 > or = levcromakalim (6.49 +/- 0.04; n = 6) > SKF94120 (5.87 +/- 0.10; n = 9). 2. When tested against the activity of the isoenzymes of cyclic nucleotide phosphodiesterase (PDE) isolated from human bronchus, SCA40 proved highly potent against PDE III (-log IC50 = 6.47 +/- 0.16; n = 4). It was markedly less potent against PDE IV (4.82 +/- 0.18; n = 4) and …

Producción de personas, reproducción de representaciones. Reflexiones sobre dos programas de capacitación en liderazgo

2020

The present paper addresses the question of the role Executive Education performs in the strengthening and reproduction of neoliberal ideology. It aims to critically reflect on the way selected contents and teaching activities operate jointly enabling or inhibiting certain perspectives regarding work in organizations. Two Leadership training programs are analyzed in this article, currently delivered by the two most prestigious business schools in Argentina: IAE Business School, and Torcuato Di Tella Business School. I begin with a general description of each one and proceed analyzing their educational proposals. Finally, the critical review reveals their consistency with a set of social rep…

Homework practices: role conflicts concerning parental involvement

2016

ABSTRACTThis article on hand discusses results of an ethnographic study which aims to perform a detailed description of practices of doing homework in a domestic environment. Based on the international state of research, first the question and the methodical approach will be explained, subsequently the role conflicts and stress ratios developed while doing homework in a family environment will be presented on the basis of two contrasting cases. To conclude, the homework-linked intrusion of school into familiar surroundings, regarding the parental involvement in contradictory requirements, will be analysed.

Negotiating the Terminological Borders of ‘Language Mediation’ in English and Italian. A Discussion on the Repercussions of Terminology on the Practi…

2015

Linguistic and cultural mediation has been playing an increasingly important role in contemporary society as a result of the intensification of international exchanges and migration flows; however, the definitions that have been given of it are still rather vague and inconsistent. In some cases linguistic and cultural mediation is seen as a broad superordinate category, comprising a range of different interlinguistic and intercultural activities serving the purpose of facilitating communication across languages, cultures and societies in various areas of civil society: industry, business, trade, law, literature, academia, institutions, public services, etc. In other cases, instead, the defi…

Sexualidad, reproducción y cultura obrera revolucionaria en España: la revista <em>Orto</em> (1932-1934)

2014

Orto. Revista de Documentacion Social, published in Valencia from 1932 to 1934, is a good example of cultural magazines in the Spanish labour movement, particularly in the world of anarcho-syndicalism. Marin Civera, its editor, sought to make Orto (which had a large and diverse range of contributors) a forum for convergence between the different working-class ideologies, united by the ideas of “Syndicalism”. In keeping with its aim to be “social documentation for the proletariat “, the journal took a strong interest in the spread of theory and practice, and debates on, sexual reform, linking these efforts to the international movement for that cause. In addition to the struggle for a new se…

‘Whose were those feelings?’ : Affect and likenessing in Halat hisar live action role-playing game

2021

Halat hisar was a live action role-playing game (larp) organized in Finland in 2016. Halat hisar’s ambition as a larp was to mirror the current situation in Palestine. In larps, participants take on different roles and improvise without the presence of an audience. Larps offer a place where emotions and affectivities are transmitted through the embodiment of characters. Larps offer forms of likenessing, which create new affective states for the players. We conclude that larps can be powerful tools for portraying political alternatives of actual events, and they can serve a role in raising awareness. Larps offer a productive context for studying subjectivities where the focus is on affectiv…
