Recent findings suggest that dispositional traits can influence personal affective forecasting. In the present study, we investigated the relationship between dispositional happiness and affective prediction about academic performance among undergraduate students. Participants were asked to predict their emotional reactions on a 7-point Likert scale, ranging from 1 (very bad) to 7 (very good), two months before they will obtain their results for one examination. All the participants were contacted by SMS the day when the results were available, and were requested to rate their present affective state on the same scale. According to their scores on the Subjective Happiness Scale, participants were assigned into “happy” and “unhappy” groups. Results show no emotional prediction differences between the two groups for extreme (i.e., very good and bad) results (upper than 8/10, and below 4/10). In contrast, happy participants predict less negative emotional state that unhappy ones for middle results (between 5/10 and 7/10). Moreover, no differences appear for the emotional state assessed the day when they received their performances. These findings confirm that dispositional happiness is related to emotional prediction, and more particularly indicate that happiness induces more positive feelings concerning moderate future achievements, but not for extreme ones. This study suggests that happiness induces a positive view about emotional coping of future intermediate accomplishments only and not a general positive view of future. [less ▲]

The authors propose that correction of dispositional inferences involves the examination of situational constraints and the suppression of dispositional inferences. They hypothesized that suppression would result in dispositional rebound. In Study 1, participants saw a video of either a free or a forced speaker. Participants shown a forced speaker later made stronger dispositional inferences about a 2nd, free speaker than control participants did. Study 2 provided evidence for higher rebound among participants who reported trying harder to suppress dispositional inferences during the Ist video. In Study 3, participants were asked to focus on situational constraints or to avoid thinking about the speaker's characteristics. Only the latter instructions led to a dispositional rebound. These data support the view that the correction of dispositional inferences involves 2 processes that lead to distinct consequences in subsequent attribution work. [less ▲]

Given a worldwide preference for suffixes over prefixes, why do some languages nonetheless have a macro-preference for prefixes? In this talk, we show that Ancient Egyptian-Coptic (Afroasiatic) shows a long-term diachronic macro-change from mixed suffixing-prefixing to an overwhel¬ming preference for prefixing. We argue that each of the micro-changes implicated in this macro-change are better understood in terms of regular changes at the level of individual constructions, via, e.g., grammaticalization, rather than in terms of a broad Sapirian ‘drift.’ Crucially, it is the particular constellation of structural features of the language at a particular moment in time, together with regular mechanisms of language change, that give rise to the cross-linguistically unusual ‘macro-preference’ of the language.

In order to investigate the physiological properties of the melanin-concentrating hormone (MCH) we have generated and used mice from which the MCH receptor 1 gene was deleted (MCHR1(Neo/Neo) mice). Complementary experimental approaches were used to investigate alterations in the learning and memory processes of our transgenic model. The ability of the knockout strain to carry out the inhibitory passive avoidance test was found to be considerably impaired although no significant differences were observed in anxiety levels. This impaired cognitive property prompted us to explore modifications in N-methyl D-aspartate (NMDA) responses in the hippocampus. Intracellular recordings of CA1 pyramidal neurons in hippocampal slices from the MCHR1(Neo/Neo) mice revealed significantly decreased NMDA responses. Finally, using in situ hybridization we found a 15% reduction in NMDAR1 subunit in the CA1 region. These results show for the first time a possible role for MCH in the control of the function of the NMDA receptor. [less ▲]

Many self-propelled microorganisms are attracted to surfaces. This makes their dynamics in restricted geometries very di erent from that observed in the bulk. Swimming along walls is bene cial for directing and sorting cells, but may be detrimental if homogeneous populations are desired, such as in counting microchambers. In this work, we characterize the motion of human sperm cells 60 um long, strongly confi ned to 25u m shallow chambers. We investigate the nature of the cell trajectories between the con fining surfaces and their accumulation near the borders. Observed cell trajectories are composed of a succession of quasi-circular and quasi-linear segments. This suggests that the cells follow a path of intermittent trappings near the top and bottom surfaces separated by stretches of quasi-free motion in between the two surfaces, as confi rmed by depth resolved confocal microscopy studies. We show that the introduction of arti cial petal-shaped corrugation in the lateral boundaries removes the tendency of cells to accumulate near the borders, an e ffect which we hypothesize may be valuable for micro fluidic applications in biomedicine.

Sepsis is a very complex clinical condition characterized by stimulation of a systemic inflammatory response due to an infection. It has a profound deleterious effect on kidney functions leading to sepsis-induced acute kidney injury (AKI). This failure seems to occur through complex mechanisms involving the immune system response, inflammatory pathways, cellular dysfunction and hemodynamic instability. To study the role of cellular energetic metabolism dysfunction and mitochondrial impairment in the occurrence of AKI during sepsis, we developed an inflammation-induced in vitro model using proximal tubular epithelial cells (HK-2) exposed to a bacterial endotoxin (lipopolysaccharide, LPS). This investigation has provided key features on the relationship between endotoxic stress and mitochondrial respiratory chain assembly defects. Firstly, we have shown that renal cells subjected to LPS are no longer capable to use adequately the available oxygen to maintain their metabolic functions. One hypothesis of this down-regulation suggests that impairment in mitochondria oxidative phosphorylation could prevent cells from using oxygen for adenosine triphosphate (ATP) production and potentially could cause sepsis-induced organ failure. Our study has then investigated this possible mitochondrial impairment to explain the decreased O2 consumption rate observed in LPS-treated HK-2 cells. After exposure to LPS, functionality of mitochondria was affected without any disturbance in their spatial organization. LPS seemed rather to interrupt mitochondrial oxidative phosphorylation by blocking cytochrome c oxidase activity. As a consequence, disruptions in the electron transport and the proton pumping across the system occurred, leading to a decrease of the mitochondrial membrane potential, an electron leakage as the form of superoxide anion, a release of cytochrome c in the cytosol and a decrease in ATP production. This irreversible defect in the production of cellular energy would support the concept that kidney failure in sepsis may occur on the basis of cytopathic hypoxia. [less ▲]
