Phenotypic and functional characterization of neutrophils and monocytes from patients with myelodysplastic syndrome by flow cytometry.

2016

Myelodysplastic syndrome (MDS) is a clonal stem cell disorder frequently associated with inefficient granulopoiesis showing dysplastic polymorphonuclear neutrophils (PMNs). To assess PMN functionality in MDS in a clinical routine setting, 30 MDS patients and ten healthy volunteers were analyzed for PMN and monocyte phenotype and function (degranulation, CD62L shedding, oxidative burst and phagocytosis) upon stimulation with lipopolysaccharide by multi-color flow cytometry (MCFC). Our data show a heterogeneous pattern for CD66, CD16 and CD64 expression on PMNs of MDS patients. CD62L shedding rate and CD66 degranulation were reduced. Interestingly, we detected correlations between the WHO ada…

Use of CD64 for the diagnosis of sepsis: a case-control study.

2010

CD64 is the high-affinity receptor of IgG. It is upregulated by inflammatory cytokines on neutrophils. The upregulation of CD64 is linked with PMN activation in SIRS or sepsis. Our aim is to verify these correlations.

"Facta non verba" : an experiment on pledging and giving

2015

International audience; We design an experiment to investigate whether asking people to state how much they will donate to a charity (i.e., to pledge) increases their actual donation. Individuals’ endowment is either certain or a random variable. We study different types of pledges, namely, private, public and irrevocable, which differ in terms of the cost to the individual for not keeping the promise. We show that in absence of endowment uncertainty, private and public pledges are associated with lower donations as compared to donations in the no-pledge case: private pledges slightly reduce donations and public pledges reduce them more significantly. Donations increase with uncertainty (in…

Cooperation and cultural transmission in a coordination game

2009

Abstract The aim of this paper is to analyze if cooperation can be the product of cultural evolution in a two-stage coordination game, consisting of a production stage followed by a negotiation phase. We present an overlapping generations model with cultural transmission of preferences where the distribution of preferences in the population and the strategies are determined endogenously and simultaneously. There are several groups in the society; some of them play cooperatively and others do not. Socialization takes place inside the group, but there is a positive rate of migration among groups which parents anticipate. Our main result shows that all groups converge to the cooperative equili…

Expected Behavior and Strategic Sophistication in the Dictator Game

2012

This paper provides novel results for the extensive literature on dictator games: recipients do not expect dictators to behave selfishly, but instead expect the equal split division. The predictions made by dictators are notably different: 45% predicted the zero contribution and 40% the equal split. These results suggest that dictators and recipients are heterogenous with regard to their degree of strategic sophistication and identify the dictator's decision power in a very different manner.

El sector no lucrativo desde el enfoque de la elección pública: Cuando la oferta no lucrativa de bienes públicos es el resultado de decisiones emanad…

2001

The voluntary supply of collective goods by nonprofit institutions has deserved little attention in the Public Choice literature, and the clasical nonprofits approach does not consider nonprofits supply as a collective decision, although individuals, either as consumers or as donors, are in the center of their theoretical constructs. In this paper we hypothesize that voluntary nonprofits' provision is a collective choice. We present a model in which the members of a community, both those who fund the nonprofits and those who do not (free riders) vote, so choosing between a political program of governmental supply and a political program of non governmental supply. Afterward, they must also …

Economía social y sector no lucrativo: Actualidad científica y perspectivas

2001

In this paper, we intend to analyze some scientific questions of current importance in the Social Economy field and Non-profit sector. In the first place, we show the growing economical importance of this field in Europe, based on the results obtained in the last transnational study. Secondly, we try to think about the concept of non-profit as well as about the position of co-operatives and associations within the Non-profit sector, introducing some criteria of analysis. Immediately after, we study this economical field under a “social” point of view. Finally, the paper analyses the place and content of Social Economy, both business and non-profit sectors, within the limits of European publ…

Neutrophil CD64 as a marker of infection in patients admitted to the emergency department with acute respiratory failure

2014

The aim of our study was to assess the CD64 expression in patients admitted to the emergency department (ED) with a triage diagnosis of acute respiratory failure (ARF) and/or dyspnea and to verify a relationship bet…
