High-level secretion of tumor necrosis factor-alpha contributes to hematopoietic failure in hairy cell leukemia [see comments]
1989
Hairy cell leukemia (HCL) is frequently associated with severe pancytopenia. The authors detected high levels of tumor necrosis factor (TNF)-alpha in the bone marrow serum of patients with HCL and found anti-TNF-alpha neutralizing monoclonal antibodies (MoAbs) to be able to enhance hematopoiesis of HCL patients in in vitro colony assays. As potent producers of TNF-alpha, hairy cells could be identified, thus implicating the malignant population in the pathogenesis of hematopoietic failure due to inappropriate secretion of this cytokine.

An Initial Security Analysis of the Personal Transaction Protocol
2003
Our society is becoming increasingly dependent on the rapid access and processing of information. The number of handheld mobile devices with access to the Internet and network-based software and services is exploding. Research indicates [1] that by the end of 2002 there will be over 1 billion mobile phone owners globally with Internet access, and that this number is going to grow exponentially in the nearest future. By 2006 the number of interconnected mobile device users is expected exceed the worldwide Internet subscriber population. It is estimated that in a few years there will be three times as many of these devices worldwide as personal computers.
L'idée de région et le fait urbain The idea of region and the urban fact
2009
Bien que la region soit un concept multiforme, voire omniforme, le decoupage regional est le cadre privilegie de la pensee spatiale et de l'action territoriale. Or la moitie des etre humains du monde, et plus des trois quarts des europeens, habitent dans une ville. Les villes produisent plus que proportionnellement a leur poids demographique, et concentrent les activites economiques de haut niveau, particulierement la production de haute technologie, les sieges sociaux, la finance et les services aux entreprises. Dans l'economie globalisee, les performances regionales semblent etre soumises a celles des villes, et les interactions economiques regionales, nationales et mondiales sont princip…
The joint emergence of group competition and within-group cooperation
2015
Abstract Between-group conflict and within-group cooperation can be seen as two sides of the same coin, coevolving in a group-structured population. There is strong support for between-group competition facilitating the evolution of human cooperative tendencies, yet our understanding of how competition arises is less clear. We show that groups of randomly assembled individuals spontaneously engage in costly group competition, and that decisions promoting between-group conflict are associated with high levels of within-group cooperation. Remarkably, when groups were given the possibility to compete against other groups, net earnings for individuals were higher than when groups were not allow…
Ethically ethnic: the ethno-culturalization of the moral conduct of the Sámi and the Roma in the governance in Finland between the 1850s and 1930s
2015
Although there was not a focused administration on ethnic minorities in Finland until the last decades of the 20th century, there was variety of rationalities, techniques and practices of governance used for their conduct. In this article I analyze how the governance of the Roma and the Sámi – two biggest minorities at the time – changed after mid-1800s, when the new understanding, the ethno-cultural one, on population diffused among administration and governing bodies. This Foucauldian analysis concentrates on the descent of this ‘event’, the social and political conditions of its mergence, and the actual changes it meant in the governance of these minorities. peerReviewed
PCOS Phenotypes: Impact on Fertility
2018
Polycystic ovary syndrome (PCOS) is characterised by an extreme heterogeneity and at least four main phenotypes may be distinguished. In referred population, anovulatory hyperandrogenic phenotype (classic PCOS or phenotypes A and B) is by far the most common phenotype and presents the most severe endocrine and metabolic alterations. Ovulatory PCOS and normoandrogenic phenotype represent a mild form of PCOS that is more common in general population and/or (normoandrogenic) in some particular ethnic group. During their life, because of changes in lifestyle or because of spontaneous changes in ovarian and adrenal androgen secretion that occur during late reproductive age, patients may move fro…
MOOCEP: Un método para construir cursos masivos para Adultos Mayores: Usando una creación MOOCEP
2018
Hoy en día, la población de adultos mayores se ha incrementado significativamente en relación al total de la población mundial, así también este segmento en los últimos años ha mostrado una mayor adherencia e interés a los avances tecnológicos, entre ellos el Internet y sus servicios con la finalidad de desarrollar diferentes actividades tales como entretenimiento, información de actualidad, aprendizaje de diferentes tópicos, entre otros. Sin embargo, las aplicaciones y sitios web no tienen en cuenta los requisitos específicos de las personas de la tercera edad. De ahí, es necesario contar con metodologías, procesos y herramientas, las mismas que tengan en cuenta formas apropiadas de intera…
The Fluid City Experience: An Update
2016
This chapter describes the actual status of thirteen European cities that become fluid cities through their strategies for urban regeneration. These cities are divided into three groups: the large port-cities, the medium rank “city-port” cities, the riverfront cities. For every city, we define the status of urban environment and population, the trend for port and airport traffic and the strategies for urban regeneration.
Population size estimation of larval coregonids in large lakes: Stratified sampling design with a simple prediction model for vertical distribution
2009
Abstract The lake-specific vertical distribution of larval coregonids was assessed annually in Finnish lakes by bongo net sampling. The effect of inter-annual and inter-lake variation in vertical distributions on population estimates of larval coregonids were analysed in 1999–2008. The vertical distribution of newly hatched vendace ( Coregonus albula (L.)) and European whitefish ( Coregonus lavaretus L. s.l.) larvae was analysed and high inter-annual and lake-specific variation in the larval vertical distribution was found. Generally, in both littoral and pelagic areas, larvae were aggregated near the water surface, mostly in the top 30 cm layer. We compared observed and predicted density e…
