Several lines of evidence attest robust relationships between personality dimensions and emotions, including cognitive aspect of emotion. More particularly, many studies reported strong relationships between extraversion, the behavioral activation system (BAS), and the cognitive processing of positive information, on the one hand, and between neuroticism, the behavioral inhibition system (BIS), and the processing of negative information, on the other hand. Recently, DePascalis, Awari, Matteucci, and Mazzocco (2005) reported that personality traits modulated the effect of the emotional visual stimuli on the mismatch negativity (MMN). The aim of the present study was to replicate these data and extend them to other personality dimensions. Auditory MMN was recorded in normal subjects simultaneously to the presentation of emotional pictures selected as neutral, positive, or negative from the International Affective Picture System, and presented in randomized order. The results support the recent finding that personality (namely, BIS and harm avoidance) modulates the influence of emotional (negative) context on auditory information processing. The present findings suggest that the modulation by personality of change detection in the unattended environment as a function of context valence is limited to unpleasant context. [less ▲]

CO2 released from combustion of fossil fuels equilibrates among the various carbon reservoirs of the atmosphere, the ocean, and the terrestrial biosphere on timescales of a few centuries. However, a sizeable fraction of the CO2 remains in the atmosphere, awaiting a return to the solid earth by much slower weathering processes and deposition of CaCO3. Common measures of the atmospheric lifetime of CO2, including the e-folding time scale, disregard the long tail. Its neglect in the calculation of global warming potentials leads many to underestimate the longevity of anthropogenic global warming. Here, we review the past literature on the atmospheric lifetime of fossil fuel CO2 and its impact on climate, and we present initial results from a model intercomparison project on this topic. The models agree that 20–35% of the CO2 remains in the atmosphere after equilibration with the ocean (2–20 centuries). Neutralization by CaCO3 draws the airborne fraction down further on timescales of 3 to 7 kyr. [less ▲]

The distribution of transparent exopolymer particles (TEP) was investigated during a coccolithophorid bloom in the northern Bay of Biscay (North Atlantic Ocean) in early June 2006. MODIS chlorophyll-a (Chl-a) and reflectance images before and during the cruise were used to localize areas of important biological activity and high reflectance (HR). TEP profiles along the continental margin, determined using microscopic (TEPmicro) and colorimetric (TEPcolor) methods, showed abundant (6.1 x 10(6)-4.4 x 10(7) L-1) and relatively small (0.5-20 mu m) particles, leading to a low total volume fraction (0.05-2.2 ppm) of TEPmicro and similar vertical profiles of TEPcolor Estimates of carbon content in TEP (TEP-C) derived from the microscopic approach yielded surface concentration of 1.50 mu mol CL-1. The contribution of TEP-C to particulate organic carbon (POC) was estimated to be 12% (molar C ratio) during this survey. Our results suggest that TEP formation is a probable first step to rapid and efficient export of C during declining coccolithophorid blooms. (C) 2009 Elsevier Ltd. All rights reserved. [less ▲]

When to stop anti-TNF therapy in Crohn's disease (CD)? This is a very important question both for patients and physicians. There is no published evidence to clearly and definitely answer this question. However data on natural history of CD, long term safety of biologics, outcome after immunosuppressors (IS) cessation and some preliminary studies on biologics cessation may help us to discuss this topic. One could argue that there is currently no good reason to stop anti-TNF therapy in a patient who is in stable remission and tolerate this drug very well. The decision to stop an anti-TNF treatment is thus currently based on a compromise between the benefits/risks and cost of such long term treatment. While it appears now clearly that prolonged anti-TNF therapy is associated with favourable outcome with sustained remission, reduced surgeries and hospitalisation as well as absence of significant increase in mortality or cancers, the cost-effectiveness which is probably favourable for short and mid-term treatment (up to one year), may be less optimal for very long term treatment. In this perspective however, prospective studies should be performed to adequately assess long term evolution, disease outcome, safety and global cost of strategies based on treatment reduction with IS maintenance alone or even full treatment cessation.

The emergence of specialized cell types and their organisation into organs and tissues involve the temporal modulation of many genes that are essential for coordinating the correct timing of instructive signals. These transcriptional changes are orchestrated with a precision that reminds that of a classical symphony. Extracellular signals are transmitted to key integrators, which then orchestrate activation or repression of specific genes. In the last decade, class IIa HDACs have emerged as crucial regulators in various developmental and differentiation processes. This review focuses on the latest studies that have provided new insights into the biological functions of class IIa HDACs and discusses important aspects of their regulation. Elucidating cellular and molecular mechanisms by which functions of class IIa HDACs are modulated could potentially lead to new therapeutic opportunities for various diseases. [less ▲]

Decidualization of endometrial stromal cells (ESCs) is critical for a successful pregnancy but the molecular mechanisms of the process are poorly understood. In this study, we investigated whether the insulin-like growth factor (IGF) network is involved in this cellular process. Expression kinetics of members of the IGF system was examined at both mRNA and protein levels during in-vitro decidualization of cultured human ESCs. We found a significant up-regulation of IGF-II as well as of IGF-I receptor and the A and B insulin receptor (InsR) isoforms. In addition, levels of the key adaptor proteins insulin receptor substrate 1 (IRS-1) and IRS-2 increased, suggesting a potential involvement of the IGF signalling pathway in the decidualization process. Expression of two IGF binding proteins, IGFBP-1 and IGFBP-4, which can inhibit IGF action, also increased. In order to determine whether IGF signalling was activated during decidualization, the phosphorylation status of the receptors and the adaptor proteins was estimated. Only IRS-2 was slightly phosphorylated in decidualized cells and was further activated by the addition of exogenous IGF-II. These results suggest that the IGF signalling pathway could play a crucial role in the functions of decidualized endometrial cells [less ▲]
