Cancer is a chronic illness that impacts both patients and family members. Spouses will often take on a caregiver role, meeting psychosocial needs such as health professional needs and information needs. This caregiver role can also create emotional distress. Moreover, spouses might experience perceived inequity characterized by a combination of feelings of overinvestment and of underbenefit. This perception of inequity can also lead to emotional distress. Given the consequences of cancer on spouses, psychological interventions may be one means for helping them to cope. In this study, cognitive and behavioural methods are proposed to spouses in order to support them facing their partner’s cancer and their own issues. The overriding objective of this study is to satisfy the psychosocial needs of cancer patient spouses. In order to reach this objective, it compares the efficacy of two methods of action: 1/ hierarchical organization of psychosocial needs and problem-solving, and 2/ hierarchical organization of psychosocial needs alone. This research also aims to assess the influence of the perception of inequity that spouses might feel on the utilization of the two methods of action. The main hypothesis was that the combination of the two methods of action would have a greater and intensified impact on the assessed dependant variables than the utilization of the hierarchical organization of psychosocial needs alone. Thirty-seven spouses were randomly assigned into two groups: the experimental group (n= 19) and the control group (n= 18). The methodology provided identical protocols to the two groups with one difference in that the training period differed in order to measure the effect of training for problem-solving skills. The average age of participants in the experimental group was 58 (SD = 11) on average, and 57 (SD = 11) in the control group. They were asked to complete several questionnaires at three different time periods with a three-week time interval (T0, T1 and T2) assessing these dependent variables: psychosocial needs and emotional distress (anxiety and depression). Socio-demographic data and the perception of inequity were only evaluated at T0. At T0, all participants realized a hierarchy of psychosocial needs. Between T0 and T1, the experimental group trained in the problem-solving method while control group trained between T1 and T2 for this method. Repeated ANOVA measures were conducted to assess the evolution of the psychosocial needs. Student t-tests were computed to assess the influence of inequity perception on the utilization of the two methods of action. The results confirmed previous findings demonstrating the psychosocial needs in spouses of cancer patients. Indeed, it appears that these participants perceive more psychosocial needs than those of similar samples. This difference might be explained by the period of our intervention which occurred earlier than in experimental designs of similar studies. The overall emotional distress felt by our participants was characterized by anxiety. Therefore, being the caregiver of a cancer patient seems to foster anxiety more than depression. The results confirmed the main hypothesis showing a significant decrease of the number of unsatisfied psychosocial needs when participants have used the two methods of action. This decrease was observed whenever the combination was implemented. In other words, the combination of the two methods of action optimized meeting psychosocial needs. However, the perception of inequity did not seem to influence the utilization of these two methods. This research presents some limitations in the form of a small sample size and of a single assessment of inequity perception at T0. Nevertheless, the results of this preliminary study remain interesting and promising: further research could enhance the employed experimental design in a larger sample in order to obtain more robust results.

Objectives: Our objective is to achieve a phenomenological cross-study of melancholic and manic crises. To do this, we analyze the relationship between these two psychopathological states by means of the concepts of "narrative identity" and "intentionality". Method: From clinical cases and with reference to various theoretical models derived from phenomenological psychopathology, we discuss similarities and differences between mania and melancholia. Results: Narrative identity is based on a double movement: that of the enunciation of a speech focused on his history and that of an act of creation. From different clinical situations, we find that: (1) the melancholic retains the ability to elaborate a narrative about his history but the creative dimension of this narrative is absent, and (2) conversely, the manic experiences only the creative dimension. Discussion: Intentionality, as the tendency of consciousness to move toward something beyond itself, proves to be the center of the manic existence without being able to set itself within the boundaries of factual constraints. The melancholic, conversely, experiences an existence in which consciousness has lost its capacity to aim beyond itself. Conclusions: Melancholia and mania are quite specific forms of being-in-world with particular identity and temporal experiences. These two states share a fundamental psychopathological feature, that we named here “manque chiasmatique”: they are disorders of the intentional movement that constitutes narrative identity, that is, of the dialectics between the rootedness (“enracinenment”) of self in its past and the possibility of creation of a new identity.

Adenosine Triphosphate (ATP) and its metabolite, adenosine, are key regulators of polymorphonuclear neutrophils (PMNs) functions. PMNs have recently been implicated in the initiation of thrombosis. We investigated the role of ATP and adenosine in PMN activation and recruitment at the site of endothelial injury. Following binding to the injured vessel wall, PMNs are activated and release elastase. The recruitment of PMNs and the subsequent fibrin generation and thrombus formation are strongly affected in mice deficient in the P2X1-ATP receptor and in wild-type mice treated with CGS 21680, an agonist of the A2A adenosine receptor or NF449 a P2X1 antagonist. Infusion of wild-type PMNs into P2X1-deficient mice increases fibrin generation but not thrombus formation. Restoration of thrombosis requires infusion of both platelets and PMNs from wild-type mice. In vitro, ATP activates PMNs, whereas CGS 21680 prevents their binding to activated endothelial cells. These data indicate that ATP contributes to PMN activation leading to their adhesion at the site of laser-induced endothelial injury, a necessary step leading to the generation of fibrin and subsequent platelet-dependent thrombus formation. Altogether, our study identifies previously unknown mechanisms by which ATP and adenosine are key molecules involved in thrombosis by regulating the activation state of PMNs. [less ▲]

Gut content examination and trophic markers (fatty acids, stables isotopes of C and N) were combined to delineate the diet of the dominant species of amphipods from Mediterranean Posidonia oceanica seagrass meadows and to highlight trophic diversity among this community. Our results indicate that, although all dominant species heavily relied on macroalgal epiphytes, considerable interspecific dietary differences existed. Carbon stable isotope ratios notably showed that some of the amphipod species favored grazing on epiphytes from leaves or litter fragments (Apherusa chiereghinii, Aora spinicornis, Gammarus aequicauda), while others like Dexamine spiniventris preferred epiphytes from rhizomes. The remaining amphipods (Caprella acanthifera, Ampithoe helleri and Gammarella fucicola) readily consumed both groups. In addition, SIAR modeling suggested that most species had a mixed diet, and relied on several food items. Fatty acid analysis and gut contents revealed that contribution of microepiphytic diatoms and of benthic and suspended particulate organic matter to the diet of amphipods were anecdotal. None of the examined species seemed to graze on their seagrass host (low 18:2(n-6) and 18:3(n-3) fatty acids contents), but G. aequicauda partly relied on seagrass leaf detritus, as demonstrated by the lesser 13C-depletion of their tissues. Overall, our findings suggest that amphipods, because of their importance in transfers of organic matter from primary producers and detritus to higher rank consumers, are key-items in P. oceanica associated food webs.

A stylistic analysis of Corazón de Kaláshnikov (2009) by Alejandro Páez Varela highlights that the novel is extremely elliptic: the focalization of the characters is external, the causal relations are implicit and the style is very much paratactic. This seems to correspond to an ethical choice for not participating in the sensationalist representations of the violence in Ciudad Juárez, an option Páez Varela shares with the Bolaño of 2666, specifically the part about the femicides. At the same time, Corazón de Kaláshnikov seems to be typical of a certain style practiced in the north of Mexico, tense and sober, and related to a peculiar geographic and climatic environment.

The submarine part of the North Anatolian Fault (NAF) in the Marmara Sea is a significant hazard for the city of Istanbul (Turkey). The use of paleoseismological data to provide an accurate seismic risk assessment for the area is constrained by the fact that the NAF system is submarine near Istanbul; thus a history of paleoearthquakes can be inferred only by using sediment cores. Here a record of turbidites was obtained in two cores and used to reconstruct the earthquake history along a main branch of the NAF, the Cinarcik Segment. Kullenberg core Klg04 (4 m long) was collected during Marmarascarps mission from a berm north of the fault and a second core (Klg03, 3.5 m long) was positioned in the Cinarcik Basin, 3 km south of the fault. Sedimentary sequences in the two cores were correlated using variations in Ca/Ti ratio, which reflect the local aquatic productivity compared with more terrigenous input. The turbidites between the two cores were then classified to distinguish the synchronous ones from the other ones. Radionuclide measurements suggest that the most recent turbidite recorded in both cores was triggered by the M=7.3 1894 earthquake. We conclude that the turbidites are earthquake-generated, based on: 1) their distinctive sedimentological and geochemical signatures, previously described and applied in the Marmara Sea; 2) the correlation of turbidites between cores at berm and basin sites; 3) the match of the most recent turbidites with a 19th century historical earthquake; and 4) the elimination of others processes. Because of its specific geomorphological location, core Klg04 likely records only mass wasting events related to the rupture on the Cinarcik Segment. To date older turbidites, we used 14C and paleomagnetic data to build an OxCal age model with a local reservoir correction (ΔR) of 400±50 yr. The Cinarcik Segment is found to have ruptured in AD1894, AD1509, sometime in the 14th century, AD989, AD740 and in the 5th century and have a mean recurrence interval of rupture between 243 and 396 years. Following the age model obtained we finally used the earthquake record history of the Cinarcik Segment to infer the rupture history of adjacent segments of the North Anatolian Fault during six earthquake cycles over the past 1500 years.

Thanks to the precision of Kepler observations, [3] were able to measure the linewidth and amplitude of individual modes (including mixed modes) in several sub- giant power spectra. We perform a forward modelling of a Kepler subgiant based on sur- face properties and observed frequencies. Non-adiabatic computations including a time- dependent treatment of convection give the lifetimes of radial and non-radial modes. Next, combining the lifetimes and inertias with a stochastic excitation model gives the ampli- tudes of the modes. We can now directly compare theoretical and observed linewidths and amplitudes of mixed-modes to obtain new constraints on our theoretical models. [less ▲]

An original experimental set-up combining a FTIR microscope with a high pressure cell has been built in order to analyze in-situ the impregnation of solute into microscopic polymer samples, such as fibers or films, subjected to supercritical CO2. Thanks to this experimental set-up, key factors governing the impregnation process can be simultaneously followed such as the swelling of the polymeric matrix, the CO2 sorption, the kinetic of impregnation and the drug loading into the matrix. Moreover, the solute/polymer interactions and the speciation of the solute can be analyzed. We have monitored in situ the impregnation of aspirin and ketoprofen into PEO (Polyethylene Oxide) platelets at T=40°C and P=5; 10 and 15 MPa. The kinetic of impregnation of aspirin was quicker than the one of ketoprofen and the final drug loading was also higher in case of aspirin. Whereas the CO2 sorption and the PEO swelling remain constant when PEO is just subjected to CO2 under isobaric conditions, we noticed that both parameters can increase while the drug impregnates PEO. Coupling these results with DSC measurements, we underlined the plasticizing effect of the drug that also leads to decrease the crystallinity of PEO in situ thus favoring the sorption of CO2 molecules into the matrix and the swelling of the matrix. The plasticizing effect increases with the drug loading. Finally, the speciation of drug was investigated considering the shift of the carboxyl bands of the drugs. Both drugs were found to be mainly homogeneously dispersed into PEO. [less ▲]

Urban sprawl is transforming our landscapes and rural areas at a spectacular pace. Measuring the strength of the phenomenon and proposing dynamic ways to delineate suburban areas have been the object of much debate amongst scientists. The present article takes the view that, beyond measuring and delineating suburban areas, more efforts should be directed to qualifying the morphology of built settlements within these areas. Therefore it proposes a method based on a semi-automatic classification system of building clusters, designed to describe and interpret the phenomenon from a morphological perspective. This method is based on a combination of field surveys with numerical analyses of digital land cadastre maps. The application of this classification system to the suburban area around Liege reveals that, far from developing in a complete indifference of local conditions, contemporary suburban settlements are influenced by landscape structures inherited from the past.

Virus-like particles (VLPs) of human papillomavirus (HPV) are used as a vaccine against HPV-induced cancer, and recently we have shown that these VLPs are able to activate natural killer (NK) cells. Since NK cells collaborate with dendritic cells (DCs) to induce an immune response against viral infections and tumors, we studied the impact of this crosstalk in the context of HPV vaccination. NK cells in the presence of HPV-VLPs enhanced DC maturation as shown by an upregulation of CD86 and HLA-DR and an increased production of IL-12p70, but not of the immunosuppressive cytokine IL-10. This activation was bi-directional. Indeed, in the presence of HPV-VLPs, DCs further activated NK cells by inducing the upregulation of cell surface activation markers (CD69 and HLA-DR). The function of NK cells was also improved as shown by an increase in IFN-gamma secretion and cytotoxic activity against an HPV+ cell line. This crosstalk between NK cells and DCs needed CD40 interaction and IL-12p70 secretion, whereas NKG2D was not implicated. Our results provide insight into how VLPs interact with innate immune cells and how NK cells and DCs play a role in the immune response induced by this vaccine agent.
