Unstable equilibrium: young adult women in family and career formation in Southern Europe

The paper examines the relationship between family formation (i.e., living with a partner and having children) and women’s occupational career in southern Europe (i.e., Greece, Italy, Portugal and Spain). The relationship is explored by analysing the impact that different family structures and male [nvolvement in caring activities have on women’s early occupational trajectories (i.e., remaining in the same occupational status, experiencing downward or upward mobility, or withdrawing from paid work). This research shows that male involvement in caring activities does not really push women ahead in their career, but the absolute lack of male support seems to negatively affect women’s permanence in paid work. These results apply to all southern European countries except Portugal, where the absolute absence of the partners’ support in caring activities does not seem to alter women’s determination to remain in paid work. The methodology applied consists of the estimation of multinomial logit regression models and the analysis is based on eight waves (1994-2001) of the European Community Household Panel (ECHP).

The Generational contract in the family : explaining regime differences in financial transfers from parents to children in Europe

The exchange of social and economic support between the generationsis one of the main pillars of both family life and welfare systems. Thedebate on how to reform the generational contract is still truncated, however, by focusing on its public dimension only, especially on pensions and health care provisions. For a full account, the transfer of resources between adult generations in the family needs to be included as well. In our previous research we have shown that intergenerationalexchange is more likely to take place but less intense in the Nordicwelfare regime than in the Continental and Southern ones. In thepresent paper we analyze the social mechanisms that create and explain this nexus between patterns of intergenerational transfers and welfare regimes. The notion that Southern European family support networksare stronger and more effective than those of Continental and Northern European countries is only partially confirmed. In Southern (and partly in Continental) countries, children are mostly supported by means of co-residence with their parents till their complete economicindependence. However, once they have left the parental home thereare fewer transfers; support tends to be restricted to children who have special needs (such as for the formation of their own family), and depends more on their parents’ resources. In the Nordic countries, in contrast, transfers are less driven by children’s needs and parentalresources.

A novel family of dehydrin-like proteins is involved in stress response in the human fungal pathogen Aspergillus fumigatus.

 During a search for genes controlling conidial dormancy in Aspergillus fumigatus, two dehydrin-like genes, DprA and DprB, were identified. The deduced proteins had repeated stretches of 23 amino acids that contained a conserved dehydrin-like protein (DPR) motif. Disrupted DprAΔ mutants were hypersensitive to oxidative stress and to phagocytic killing, whereas DprBΔ mutants were impaired in osmotic and pH stress responses. However, no effect was observed on their pathogenicity in our experimental models of invasive aspergillosis. Molecular dissection of the signaling pathways acting upstream showed that expression of DprA was dependent on the stress-activated kinase SakA and the cyclic AMP-protein kinase A (cAMP-PKA) pathways, which activate the bZIP transcription factor AtfA, while expression of DprB was dependent on the SakA mitogen-activated protein kinase (MAPK) pathway, and the zinc finger transcription factor PacC. Fluorescent protein fusions showed that both proteins were associated with peroxisomes and the cytosol. Accordingly, DprA and DprB were important for peroxisome function. Our findings reveal a novel family of stress-protective proteins in A. fumigatus and, potentially, in filamentous ascomycetes.

Implication of TNF family members in the immune response to the infection with the intracellular protozoan parasite "Leishmania major"

Suite à une infection avec le protozoaire Leishmania major (L. major), les souris sensibles de souche BALB/c développent des lésions progressives associées à une maturation des cellules CD4+ TH2 sécrétant de l'IL-4. A l'inverse, les souris résistantes de souche C57BL/6 guérissent à terme, sous l'influence de l'expansion des cellules CD4+ TH1 produisant de l'IFNy qui a un effet synergique avec le TNF ("tumor necrosis factor") sur l'activation des macrophages et leur fonction leishmanicide. Lors de notre étude nous avons montré que des souris C57BL/6 doublement déficientes en TNF et FasL ("Fas ligand") infectées par L. major ne guérissaient ni leur lésions ni ne contrôlaient la réplication de parasites malgré une réponse de type TH1. Bien que l'activité de synthétase inductible de l'oxyde nitrique ("iNOs") soit comparable chez les souris doublement ou simplement déficientes, seules celles déficientes en FasL ont démontré une incapacité à contrôler la réplication parasitaire. De surcroît il est apparu que le FasL a un effet synergique avec l'IFNy. L'adjonction de FasL à une culture cellulaire de macrophages stimulés par l'IFNy conduit à une activation de ces cellules. Celle-ci est démontrée par l'augmentation de la production de TNF et de NO par les macrophages ainsi que par l'élimination des parasites intracellulaires par ces mêmes cellules. Alors que le FasL et l'IFNy semblent essentiels au contrôle de la réplication des pathogènes intracellulaires, la contribution de TNF s'oriente davantage vers le contrôle de l'inflammation. L'activation macrophagique via Fas précède la mort cellulaire qui survient quelques jours plus tard. Cette mort cellulaire programmée était indépendante de la cascade enzymatique des caspases, au vu de l'absence d'effet de l'inhibiteur non-spécifique ZVAD-fmk des caspases. Ces résultats suggèrent que l'interaction Fas-FasL agit comme une costimulation nécessaire à une activation efficace des macrophages, la mort cellulaire survenant consécutivement à l'activation des macrophages.¦-¦Upon infection with the protozoan parasite Leishmania major (L. major), susceptible BALB/c mice develop non healing lesions associated with the maturation of CD4+ TH2 cells secreting IL-4. In contrast, resistant C57BL/6 mice are able to heal their lesions, because of CD4+ TH1 cell expansion and production of high levels of IFNy, which synergizes with tumour necrosis factor (TNF) in activating macrophages to their microbicidal state. In our study we showed that C57BL/6 mice lacking both TNF and Fas ligand (FasL) infected with L. major neither resolved their lesions nor controlled L. major replication despite a strong TH1 response. Although comparable inducible nitric oxide synthase (iNOs) was measured in single or double deficient mice, only mice deficient in FasL failed to control the parasite replication. Moreover FasL synergized with IFNy for the induction of leishmanicidal activity within macrophages infected with L. major in vitro. Addition of FasL to IFNy stimulated macrophages led to their activation, as reflected by the secretion of tumour necrosis factor and nitrite oxide, as well as the induction of their microbicidal activity, resulting in the killing of intracellular L. major. While FasL along with IFNy and iNOs appeared to be essential for the complete control of intracellular pathogen replication, the contribution of TNF appeared more important in controlling the inflammation on the site of infection. Macrophage activation via Fas pathway preceded cell death, which occurred a few days after Fas mediated activation. This program cell death was independent of caspase enzymatic activities as revealed by the lack of effect of ZVAD-fmk, a pan-caspase inhibitor. These results suggested that the Fas-FasL pathway, as part of the classical activation pathway of the macrophages, is essential in the stimulation of macrophage leading to a microbicidal state and to AICD, and may thus contribute to the pathogenesis of L. major infection.

Le corps à l'ouvrage : les représentations du corps dans les récits de voyage d'Ella Maillart, d'Annemarie Schwarzenbach, de Nicolas Bouvier et de Lorenzo Pestelli

Dans les années trente, Ella Maillart et Annemarie Schwarzenbach quittent la Suisse pour l'Afghanistan. Deux décennies plus tard, L. Pestelli et N. Bouvier s'embarquent à leur tour sur les routes d'Orient. Filles et fils de grands industriels, d'universitaires ou de diplomates, ces quatre écrivains-voyageurs mettent un point d'honneur à s'éloigner d'une conception bourgeoise du voyage en présentant leur départ comme un moyen de se définir dans l'ailleurs, c'est-à-dire en dehors de leur héritage social, familial, national et occidental. L'Orient leur semble le lieu des possibles. Or, malgré leur désir de table rase, ils s'aperçoivent vite que, quoi qu'ils fassent, leur corps porte les stigmates de l'Occident. Ils vont donc tenter de le modifier. Si le but du voyage n'est pas de faire totalement disparaître le corps, ce n'est qu'en le risquant, en l'offrant au monde, pour le meilleur et souvent pour le pire, que les voyageurs croient pouvoir goûter aux délices du dehors. Mais ce bonheur charnel, physique, sensuel voire érotique, comment le dire ? Et quelle langue adopter pour rendre compte de sa présence physique au monde ? La réunion de ces quatre auteurs d'époques, de genres et de plumes différents, nous permet d'observer l'évolution des représentations du corps dans le récit de voyage au vingtième siècle tout en questionnant nos habitudes de lecture. Quelle représentation attendons-nous du corps dans un récit de voyage ? Celui-ci est-il vraiment le lieu privilégié pour remettre le corps à l'ouvrage ? The Boby at work. Body representations ìn the narratives of Eila Maillart, Annemarie Schwarzenbach, Nicolas Bouvier and Lorenzo Pestelli. In the 1930s, Ella Maillart and Annemarie Schwarzenbach left Switzerland for Afghanistan. Two decades later, Lorenzo Pestelli and Nicolas Bouvier set out on the routes to the East. Daughters and sons of prominent industrialists, academics or diplomats, these four writer-travellers made a point of straying away from the bourgeois conception of travel by presenting their departure as a way of defining the self away from social, family, national and Western inheritance. The East appears to them as the location of many possibilities. Yet, in spite of their desire for a clean slate, they soon realise that, no matter what they do, their body carries the stigma of the West. They will thus try to modify it. If the aim of their travelling is not to make the body disappear completely, it is only by putting it at risk and by offering it to the world, for better and often for worse, that the travellers believe they can taste the delights from the outside. But how to put in words this carnal, physical, sensual and even erotic pleasure? And what language can be chosen to account for one's presence in the world? Working jointly on four writers, from different eras, genres and styles, helps us to observe the evolution of the representations of the body in travel literature in the 20`h century and at the same time it questions our reading habits. What representations of the body do we expect in travel literature? Is travel literature really the privileged location to put the body back to work?

Impact of family structure on long-term survivors of osteosarcoma

Rapport de synthèse : But du travail : le pronostic des patients atteints d'ostéosarcome s'est considérablement amélioré grâce à l'utilisation de thérapies combinées performantes. Cependant, ces traitements agressifs sont grevés de complications chroniques. Notre travail a consisté à l'évaluation du status fonctionnel, psychologique et familial chez des patients survivants au long cours d'ostéosarcome traités au centre pluridisciplinaire d'oncologie. Patients et méthodes: 15 survivants au long cours d'ostéosarcome ont été évalués à la recherche de séquelles physiques et psychologiques. Pour l'évaluation fonctionnelle, nous avons utilisé la méthode de Enneking. L'évaluation psychologique a été basée sur un test d'évaluation globale (GHQ-28), sur un test de cohésion familiale (FAST test) et sur une échelle d'évaluation de symptômes post-traumatiques. Résultats: sur le plan fonctionnel, seuls 5 patients présentaient des séquelles graves et 10 des handicaps modérés. 4 patients souffraient de symptômes dépressifs. 6 patients ont décrit uns structure familiale déséquilibrée dont 3 des 4 patients avec des symptômes dépressifs, les 4 patients avec symptômes post-traumatiques et 5 des 7 patients avec une mauvaise acceptation émotionnelle. Conclusions: la plupart des patients souffrant d'ostéosarcome présentent une bonne récupération fonctionnelle. Seule une minorité reste sévèrement handicapée. Un tiers des patients souffre de symptômes dépressifs et de stress post-traumatique. Une mauvaise acceptation émotionnelle est fortement liée à une structure familiale déséquilibrée. La situation psychologique et familiale des patients atteints d'ostéosarcome doit donc être rapidement prise en compte afin d'améliorer leur évolution au long cours.

Que faire d'un stagiaire dans votre consultation [Tips for hosting a medical student in a PC consultation].

Hosting a medical student in one's primary care consultation challenges the practitioner to be a clinical teacher as well as providing high-quality patient care. A few tips can make this double task easier. Before the consultation it is possible to define the student's learning objectives and to plan the consultation. During the consultation itself some teaching models exist (One minute preceptor, SNAPP) that facilitate the teaching by maximising the teaching moments for each student-patient encounter. And finally after the consultation a time of reflection where both student and clinical teacher can think about what went well and what could be done better.

A novel protein family mediates Casparian strip formation in the endodermis.

Polarized epithelia are fundamental to multicellular life. In animal epithelia, conserved junctional complexes establish membrane diffusion barriers, cellular adherence and sealing of the extracellular space. Plant cellular barriers are of independent evolutionary origin. The root endodermis strongly resembles a polarized epithelium and functions in nutrient uptake and stress resistance. Its defining features are the Casparian strips, belts of specialized cell wall material that generate an extracellular diffusion barrier. The mechanisms localizing Casparian strips are unknown. Here we identify and characterize a family of transmembrane proteins of previously unknown function. These 'CASPs' (Casparian strip membrane domain proteins) specifically mark a membrane domain that predicts the formation of Casparian strips. CASP1 displays numerous features required for a constituent of a plant junctional complex: it forms complexes with other CASPs; it becomes immobile upon localization; and it sediments like a large polymer. CASP double mutants display disorganized Casparian strips, demonstrating a role for CASPs in structuring and localizing this cell wall modification. To our knowledge, CASPs are the first molecular factors that are shown to establish a plasma membrane and extracellular diffusion barrier in plants, and represent a novel way of epithelial barrier formation in eukaryotes.
