Modification of hosts' behavior by a parasite: field evidence for adaptive manipulation.

2007

9 pages; International audience; Parasites relying on trophic transmission to complete their life cycles often induce modifications of their host's behavior in ways that may increase their susceptibility to predation by final hosts. These modifications have often been interpreted as parasite adaptations, but very few studies have demonstrated that host manipulation has fitness benefits for the parasite. The aim of the present study was to address the adaptive significance of parasite manipulation by coupling observations of behavioral manipulation to estimates of trophic transmission to the definitive host in the natural environment. We show that the acanthocephalan parasite Pomphorhynchus …

Phenotyping: Case study of legumes plants

2012

International audience; The activities of the GEAPSI group, belonging to the large research unit Agroecology, is devoted to the genetic improvement of legumes important for European agriculture, and focuses on the cultivated species pea (Pisum sativum) and the field bean (Vicia faba). These studies are supported by basic research on a model legume, Medicago truncatula, used for taking advantage of the extensive genomics information available. Some examples will first illustrate how the combination of analytical, non-destructive phenotypical measurements and modelling can improve our understanding of plant functioning, taking as case studies legumes plants. The presentation will then describ…

Les salauds vont en enfer : pièce en 2 actes

2015

International audience; On connaît Frédéric Dard romancier, on connaît moins Frédéric Dard auteur dramatique, scénariste ou dialoguiste. L'auteur a pourtant écrit de nombreux textes pour le théâtre. Certaines pièces sont parues en livres ou dans des revues, mais la plupart d'entre elles ont été jouées sans que le texte fasse l'objet d'une publication. C'est le cas de la pièce 'Les salauds vont en enfer'. Montée au théâtre du Grand-Guignol à Paris en 1954 et mise en scène par Robert Hossein, cette pièce a connu un destin particulier car elle a fait l'objet de trois transpositions particulièrement intéressantes. Dès 1955, en effet, l'adaptation cinématographique est confiée à Robert Hossein e…

“Mise en Cadre” of the Social Drama in Joe Wright's Pride & Prejudice (2005)

2006

Cet article s'intéresse aux effets très originaux de « mise en cadre » dans cette récente adaptation du roman de Jane Austen, notamment l'emploi de la caméra mobile (Steadycam et caméra à l'épaule), du hors-champ et de l'espace. Cet élément de l'écriture filmique est utilisé pour articuler la thématique de la classe sociale avec l'identité générique et l'origine littéraire du film. Ainsi, la caméra mobile contribue à la théâtralité du film tout en marquant les limites du champ visuel de la caméra qui permet, par contre, d'apercevoir en arrière-plan les serviteurs, le plus souvent hors-texte dans le roman. La gestion de l'espace, elle, permet à la fois d'opposer et de mêler les différentes c…

Soft tissue integration of different abutment surfaces: An experimental study with histological analysis

2021

OBJECTIVE To evaluate whether abutment surface and surface bio-activation have an effect on soft tissue morphogenesis. MATERIALS AND METHODS 36 patients (36 implants) were included. Abutments were randomly divided into 4 groups (n = 9): Smooth Surface-MAChined (MAC), Ultrathin Threaded Microsurface (UTM), MAC Plasma of Argon activated (Plasma-MAC), and UTM Plasma of Argon activated (Plasma-UTM). After 2 months of healing, soft tissue samples were collected and prepared for histological analysis. The margin of the peri-implant mucosa (PM), the apical extension of the barrier epithelium (aJE), and the apical location of the abutment (AM) were identified. Significances of differences among gro…

Taking action or thinking about it? : State orientation and rumination are correlated in athletes

2019

Athletic performance in competitive sports relies heavily on the ability to cope effectively with stressful situations. In contrast, some athletes report that their thoughts revolve around the future or past and not around the actual demands during competitions. In those specific stressful situations, the lack of focus like an unintended fixation on repetitive cognitions can have fatal consequences with regard to the performance. Especially when competitors are close in their athletic capabilities, differences in effectively coping with stress and mental stability may decide about winning and losing. One established factor of performing effectively under pressure is the individual tendency …

Ventilatory chemosensitivity, cerebral and muscle oxygenation, and total hemoglobin mass before and after a 72-day mt. Everest expedition.
